NOTIFICATION SIGNAL CONTROL APPARATUS AND METHOD

Abstract

A first notification signal generation apparatus (first music playback apparatus) is attached to an upper arm of a first exercising person. The first notification signal generation apparatus includes a display, an operation button 4a, and a sensor that detects an exercise condition of the first exercising person 1a, such as repetition tempo. The sensor is either built in, or connected external to, the first notification signal generation apparatus. A second notification signal generation apparatus (second music playback apparatus) also includes the same elements as the first notification signal generation apparatus. A second exercising person performs repetitive exercise in synchronization with a repetition notification tempo (music tempo) of a notification signal (music), and therefore shares a value of certain exercise information, obtained during his or her repetitive exercise, with the first exercising person. Thus, the first and second exercising person can share a value of certain exercise information.

Description

BACKGROUND

The present invention relates to a notification signal control apparatus suitable for sharing exercise information, such as repetition tempo, between plural exercising persons while the exercising persons perform repetitive exercise.

Conventionally, while an exercising person performs repetitive exercise, such as walking, jogging, and dancing, the exercising person plays and listens to the music suitable for the exercise with a portable music player.

For example, there is a known technique that an exercise tempo (repetition tempo) of an exercising person is detected to reproduce music data with a music tempo corresponding to the detected exercise tempo (see US 2007/0169614A1 which corresponds to JP 2007-193907A). As for running or the like, a value of the repetition tempo indicates how many steps, including both right-foot steps and left-foot steps, the exercising person has taken per unit time (e.g. one minute).

There is another known technique that a heart rate of an exercising person is detected to specify a music tempo value such that a difference between the detected heart rate and a target heart rate is reduced, and to reproduce music data with a music tempo value corresponding to the specified music tempo value, thereby to control the heart rate (see US 200710169614A1 which corresponds to JP 2007-193908A).

An apparatus provided with the aforementioned techniques called “free workout mode” and “fitness mode” as well as with a “training mode” has been commercially available. In the “training mode,” target values (pace [minute: second/km], exercise tempo [bpm], heart rate [bpm], and exercise intensity [%]) are preset for each of plural intervals (time or distance) to create an exercise program and perform repetitive exercise according to the program (see “BF-11 Manual,” [online], Yamaha Corporation, the Internet<URL:http://www2.yamaha.co.jp/manual/pdf/emi/japan/others/bf11_ja_om_v10b.pdf).

There is a still another known technique that each time an exercising person walks a certain distance, the elapsed time, exercise intensity, heart rate, and walking tempo are transmitted from the portable terminal to the distribution site on the Internet. Song data having a music tempo that approximately matches the walking tempo to provide the optimum load to the exercising person is searched on the distribution site, and is then distributed to the portable terminal to reproduce the song data (see JP 2003-108154A).

However, the aforementioned techniques are all designed to play music that fits the exercise information on the exercising person him or herself, such as repetition tempo and exercise intensity. Thus, even when the exercising person exercises with another exercising person, the exercising person cannot feel togetherness with the other exercising person during the exercise.

In contrast, there is a known technique that plural exercising persons can share values of their exercise information on the network (see paragraphs 0110, 0117, and 0120 in US 2008/0200312A1 which corresponds to paragraphs 0082, 0089, and 0092 in JP 2010-517725A).

In this technique, exercise information on plural exercising persons is collected through a music player (portable terminal) for each of the exercising persons based on an output from an acceleration sensor located on his or her shoe. The collected exercise information is transferred to an exercise information display configuration device (center) on the network and is then stored in a storage device.

The exercise information on each exercising person is displayed with the bar graph on the display screen to show his or her progress toward the challenging goal. Also, in the exercise history of the other exercising persons, the exercise information on the other exercising persons and the exercise information on the exercising person him or herself are displayed by ranking.

However, the exercising person cannot know the exercise information on the other exercising persons in real time during the exercise. This prevents the exercising person from feeling togetherness or feeling as if he or she is running with someone during the exercise.

SUMMARY OF THE INVENTION

The present invention has been achieved to solve the above problems and an object of the present invention is to provide a notification signal control apparatus that outputs a notification signal to allow a first exercising person and a second exercising person to share a value of certain exercise information and perform repetitive exercise.

In view of the foregoing, it is an object of the present invention to provide a notification signal control apparatus (27b) for providing a notification synchronized with repetitive exercise performed by a first exercising person (1a) to a second exercising person (1b), which comprises: an exercise information obtaining section (22b) that obtains exercise information related to exercise performed by the first exercising person (1a) in order for the second exercising person (1b) to utilize the exercise information; a repetition-notification-tempo specifying section (25b) that specifies, based on the obtained exercise information, a repetition notification tempo synchronized with repetitive exercise performed by the first exercising person in order for the second exercising person to perform repetitive exercise; and a notification signal generation controller (26b) that controls a notification signal generator (28b) to generate a notification signal with a tempo corresponding to the repetition notification tempo specified by the repetition-notification-tempo specifying section.

According to the invention, the second exercising person senses the repetition notification tempo of the notification signal, and performs repetitive exercise in synchronization with the repetition notification tempo. This allows the second exercising person to share a value of certain exercise information with the first exercising person and perform the repetitive exercise.

Specific examples of the exercise information are a repetition tempo (i.e. a tempo of repetitive exercise), an exercise speed (exercise pace), an exercise distance, exercise intensity, and a calorie consumption. The exercise information may include at least either one of these examples. It should be understood that the notification signal generation controller may not necessarily output a notification signal with a tempo value equal to the specified repetition notification tempo value. More specifically, to output a notification signal with a tempo corresponding to the specified repetition notification tempo indicates to output a notification signal with a tempo that may be approximately equal to or similar to or in harmony with the specified repetition notification tempo. This is because when the notification signal is music, it is not always possible to output music with a tempo value equal to the specified tempo value. Alternatively, the notification signal with a tempo value approximately equal to an integral submultiple or an integral multiple of (i.e. in harmony with) the specified repetition notification tempo value may be output. As described above, when there is a multiple relation between the tempo value and the repetition notification tempo value, the second exercising person can also perform the repetitive exercise in synchronization with the repetition notification tempo easily. Particularly, a half of the specified repetition notification tempo value is referred to as “half tempo.”

There is a case when the notification signal is music, and there is not any music available with a music tempo value that coincides with, or is approximately equal to, the specified value among a limited number of pieces of music stored in the storage device. In this case, music with a music tempo value that is an integral submultiple or an integral multiple of the specified tempo value, particularly music with the “half tempo” may be selected exceptionally. Whether or not a notification signal (music) with an exceptional music tempo, such as “half tempo,” is permitted to be output may be preset through the exercising person's operation.

According to an embodiment of the invention, the exercise information indicates a repetition tempo of the repetitive exercise performed by the first exercising person. Also, the repetition-notification-tempo specifying section (25b) specifies a repetition notification tempo corresponding to the repetition tempo of the first exercising person (1a), the repetition tempo being indicated by the exercise information.

The second exercising person senses a repetition notification tempo of a notification signal, and then performs repetitive exercise in synchronization with the repetition notification tempo. This allows the second exercising person to perform the repetitive exercise with the repetition tempo of the first exercising person. The repetition-notification-tempo specifying section can be easily achieved.

According to an embodiment of the invention, the repetition-notification-tempo specifying section (25b) calculates a repetition tempo for the second exercising person (1b) based on the obtained exercise information, and specifies a repetition notification tempo corresponding to the calculated repetition tempo. The repetition-notification-tempo specifying section can thus be easily achieved.

Particularly, in the case when the exercise information is an exercise speed for running (including walking and jogging), the repetition-notification-tempo specifying section can convert the exercise speed value into a repetition tempo value of the second exercising person by dividing the exercise speed value of the first exercising person by a stride of the second exercising person. The second exercising person senses a repetition notification tempo of a notification signal, and then performs repetitive exercise in synchronization with the repetition notification tempo. This allows the second exercising person to perform the repetitive exercise at the exercise speed of the first exercising person. Generally, exercising persons have different stride lengths. Therefore, when the first exercising person and the second exercising person share an exercise speed value, they perform repetitive exercise with different repetition tempos.

According to an embodiment of the invention, the exercise information obtaining section (22b) further obtains second exercise information related to repetitive exercise performed by the second exercising person in real time during the exercise performed by the second exercising person. Also, the repetition-notification-tempo specifying section (25b) compares a value indicated by first exercise information and a value indicated by the second exercise information, and increases or decreases a current value of the repetition notification tempo to reduce a difference between the compared values. Thus, even when a value of certain exercise information on the second exercising person is significantly different from a value of the certain exercise information on the first exercising person, these values can coincide with each other as the time elapses.

According to an embodiment of the invention, the notification signal is music, while the repetition notification tempo is a music tempo. Also, the notification signal generation controller (26b) controls the notification signal generator (28b) to produce music with a music tempo corresponding to the music tempo specified by the repetition-notification-tempo specifying section (25b). The notification signal is music, which means that the exercising person can sense the repetition notification tempo while listening to the lively music. This helps the exercising person continue repetitive exercise without getting bored of the exercise.

There is a case when plural pieces of music together with their respective music tempo values are stored in a storage device. In this case, the notification signal generation controller may select music with a music tempo corresponding to the repetition notification tempo from the plural pieces of music stored in the storage device, and may cause the notification signal generation section to output the selected music. The aforementioned music is generally existing music song data. However, the music may not necessarily be complete music song data, but may be an extracted part of the existing music song data. Preferably the music data may be stored in a wave format (such as WAV file and MP3 file) in the storage device. However, the music data may also be stored in a performance data format (mid file), such as MIDI sequence data, that records the song performance data containing information on the pitch and duration of the note. The aforementioned music may not be necessarily stored in advance in the storage device, but may be automatically produced by an automatic music production apparatus or a program section.

The aforementioned inventions may also be applied to the case when there are three or more exercising persons. Each of the exercising persons may designate the first exercising person (1a), while the other exercising persons may act as the second exercising persons (1b). Thus, in the notification signal control apparatus of the inventions, the exercise information obtaining section (22b) for the second exercising person obtains exercise information on the second exercising person (1b) in real time during the repetitive exercise performed by the second exercising person (1b), and supplies the exercise information to other exercise information obtaining sections (22a and so forth) for other exercising persons (1a and so forth). Such notification signal control apparatus achieves not only the function of the notification signal control apparatus for the second exercising person, but also the function of the notification signal control apparatus for the first exercising person when the second exercising person is designated as a first exercising person by the other exercising person. It should be understood that even when there are only two exercising persons, they can designate their partner each other as a first exercising person so that they can set a value of their partner's exercise information as a target to perform repetitive exercise.

The first exercising person (1a) and the second exercising person (1b) are real human beings. However, the first exercising person (1a) may be a virtual exercising person who behaves like a real human being. In this case, the first exercising person (1a) may not be allowed to perform repetitive exercise accurately in accordance with the preset sequence data of the exercise information (time-versus-exercise information data). For example, repetitive exercise with natural “fluctuations” may be simulated for the virtual first exercising person (1a), so that his or her exercise information may be generated based on the simulated exercise.

It should be understood that reference numerals in parentheses, which are assigned to the aforementioned respective components, are used in the drawings to represent the corresponding elements to those respective components, which are described in an embodiment of the invention. The embodiment of the invention will be described later. The reference numerals in parentheses are provided for illustration purpose only, and not for the purpose of limiting the claimed inventions.

According to the invention, the second exercising person senses a repetition notification tempo of a notification signal, and performs repetitive exercise in synchronization with the repetition notification tempo. The invention thus provides the effect that the second exercising person can share a common value of certain exercise information with the first exercising person. To share certain exercise information is not merely to understand a value of the exercise information in the brain, but to share the information by sensing a repetition notification tempo of a notification signal, and further to experience a sense of sharing through performing repetitive exercise by the exercising person him or herself.

For example, even when plural exercising persons are distanced from each other while exercising, the exercising persons can experience motions of the repetitive exercise performed by one or both of the exercising persons through the medium of the notification signal. This allows the exercising person who is exercising even alone to have a feel of bonding together with the other exercising person. This motivates the exercising person to continue exercising. When the exercise information is an exercise speed, for example, the exercising person can feel as if he or she is running together with the other exercising person at the same speed.

When the first exercising person is a coach, while the second exercising person is an athlete, for example, the athlete can perform repetitive exercise in synchronization with the exercise information on the coach who is actually exercising, such as an ideal pace value. This allows the athlete to receive effective guidance from the coach, not through the words from the mouth, but through the athlete's own experience. In addition, the coach can adjust his or her own exercise conditions (e.g. speed up or slow down the repetition tempo), while directly visually checking the exercise conditions of the athlete or monitoring the image of the athlete, which is captured by the TV camera, or checking a value of the exercise information on the athlete. This helps the coach provide more effective guidance to the athlete.

The present invention may be constructed and implemented not only as the apparatus invention as discussed above but also as a method invention. Also, the present invention may be arranged and implemented as a software program for execution by a processor such as a computer or DSP, as well as a non-transitory storage medium storing such a software program. In this case, the program may be provided to a user in the storage medium and then installed into a computer of the user, or delivered from a server apparatus to a computer of a client via a communication network and then installed into the client's computer. Further, the processor used in the present invention may comprise a dedicated processor with dedicated logic built in hardware, not to mention a computer or other general-purpose type processor capable of running a desired software program.

DETAILED DESCRIPTION

FIG. 1 is an overall configuration diagram of a notification signal generation system to illustrate one embodiment of the present invention. In FIG. 1, reference numerals 1a and 1b respectively denote a first exercising person and a second exercising person. They are real individuals who perform repetitive exercise. The first exercising person 1a and the second exercising person 1b may reside in different areas away from each other.

A first notification signal generation apparatus 2a (first terminal) is attached to a part of the body (e.g., upper arm) of the first exercising person 1a. The first notification signal generation apparatus 2a includes a display 3a, an operation button 4a, and a sensor 5a that detects an exercise condition (or motion) of the first exercising person 1a. The sensor 5a is either built in, or connected externally to, the first notification signal generation apparatus 2a. A second notification signal generation apparatus 2b (second terminal) also includes the same elements as the first notification signal generation apparatus 2a.

The notification signal generation system allows the second exercising person 1b to perform repetitive exercise in synchronization with a repetition notification tempo of a notification signal, so that the second exercising person 1b can share a value of certain exercise information with the first exercising person 1a, obtained during his or her repetitive exercise and perform the repetitive exercise. The repetitive exercise is typically athletics, such as running, jogging, and walking. However, the repetitive exercise may also be gymnastics such as push-ups or dance such as aerobics or swimming, or may also be exercises using training machines such as bicycle ergo meter, treadmill, and strength machine. The exercising person may also be referred to as athlete or player. Any kind of exercises that involve repetitive motions is defined as the repetitive exercise. The certain exercise information includes, for example, a repetition tempo, an exercise speed (exercise pace), an exercise distance, exercise intensity, and a calorie consumption. The “repetition tempo” indicates a tempo of the repetitive exercise. The second exercising person 1b can select any of the exercise information through operating the second notification signal generation apparatus 2b.

The notification signal is, for example, an audible sound, such as beep with variable repetition period (single-tone electronic beep generated intermittently), metronome sound with a timbre (rhythmic musical instrument sound), and music with scales. In the case when the notification signal is music, the first and the second notification signal generation apparatuses 2a and 2b may be each referred to as music playback apparatus, and more specifically, portable music player. The notification signal may also be a visual notification signal that has variable brightness, tint or the like depending on the repetition notification tempo. The visual notification signal may be output from a light-emitting indicator or be indicated on the display. The repetition notification tempo can be the reciprocal of the repetition period of the beep, a music tempo or a flashing tempo, depending on the cases.

In the illustrated example, the first and second notification signal generation apparatuses 2a and 2b output notification signals respectively to sensory organs (ear) of the first and second exercising persons 1a and 1b through their earphones 6a and 6b. The first and second notification signal generation apparatuses 2a and 2b can be connected to a communication network 8 respectively through arbitrary wireless transmission paths 7a and 7b. The communication network 8 is the Internet, for example. The wireless transmission paths 7a and 7b each are a mobile phone network provided by a mobile phone company, a Wireless Fidelity (Wi-Fi) standard wireless Local Area Network (LAN) or a Worldwide Interoperability for Microwave Access (WiMAX) standard wireless access channel, for example.

Exercise information on the first exercising person 1a is transmitted to the second exercising person 1b via the communication network 8 in real time. The second exercising person 1b senses the exercise information through the repetition notification tempo or variations in the repetition notification tempo. In the illustrated example, an exercise information management center (e.g., server) 9 is connected to the communication network 8. The first notification signal generation apparatus 2a supplies the exercise information on the first exercising person 1a to the second notification signal generation apparatus 2b via the exercise information management center 9 that serves as a relay device. Alternatively, the first notification signal generation apparatus 2a may be a peer-to-peer notification signal generation system that supplies the exercise information on the first exercising person 1a to the second notification signal generation apparatus 2b without passing via the exercise information management center 9.

The exercise information management center 9 not only has the aforementioned function of relaying the exercise information, but also has functions of storing exercise information and/or statistical information on the exercise results, which are transferred from the first and second notification signal generation apparatuses 2a and 2b, in a storage device separately for the first and second exercising persons 1a and 1b, comparing the exercise results between the first and second exercising persons 1a and 1b, and storing the comparison results.

A display screen is created based on the exercise information, the statistical information, and the comparison results, and is displayed on the respective displays 3a and 3b of the first and second notification signal generation apparatuses 2a and 2b through the communication network 8. This allows the first and second exercising persons 1a and 1b to share a numerical value of the exercise information. In the illustrated example, a personal computer 10 is connected to the communication network 8 either directly or via a router 11. The personal computer 10 can also access the exercise information management center 9 to view the aforementioned display screen.

FIG. 2 is a functional block diagram that illustrates the embodiment of the invention. In FIG. 2, the same or like elements are denoted by the same reference numerals. Functions of the individual sections in the first notification signal generation apparatus 2a and the second notification signal generation apparatus 2b, when these apparatuses 2a and 2b serve respectively as the first music playback apparatus and the second music playback apparatus, will be described in brackets.

The first notification signal generation apparatus 2a and the second notification signal generation apparatus 2b have the same configuration. However, it is assumed in the following description that the first notification signal generation apparatus 2a is set in an “independent mode” in which a notification signal (music) is output only based on the exercise information on the first exercising person 1a, while the second notification signal generation apparatus 2b is set in a “dependent mode” in which a notification signal (music) is output based on a value of certain exercise information obtained from another exercising person or in the illustrated example, from the first notification signal generation apparatus 2a.

The second exercising person 1b senses a repetition notification tempo (music tempo) of a notification signal (music), and performs repetitive exercise in synchronization with the repetition notification tempo. This allows the second exercising person 1b to share a value of certain exercise information with the first exercising person 1a and perform the repetitive exercise.

As discussed in the description of BACKGROUND of the present disclosure, specific examples of the “independent mode” are “free workout mode” (music mode 1 that will be described later with reference to FIG. 7A), “fitness mode” (music mode 2 that will be described later with reference to FIG. 7B), and “training mode.” On the other hand, examples of the “dependent mode” are music modes 3A and 3B that will be described later with reference to FIGS. 7C and 7D.

In the first notification signal generation apparatus 2a, an operation mode selection section 21a sets the “independent mode” for a first exercise information obtaining section 22a. A sensor (detector) 23a sequentially outputs a value that is detected in real time during the repetitive exercise performed by the first exercising person 1a to the first exercise information obtaining section 22a. In the “independent mode,” the first exercise information obtaining section 22a functions as an own exercise information generation section that generates one or more kinds of exercise information based on a value that is output from the sensor 23a. The sensor (detector) 23a may be adapted to detect at least one of motion performed by the exercising person and a physical reaction of the exercising person.

In the case when the sensor 23a is provided with an acceleration sensor, the first exercise information obtaining section 22a obtains a repetition tempo value (e.g., the number of times of repetition per minute) based on a detected value of an interval between impacts, which is output from the acceleration sensor. If the repetitive exercise is running, jogging or walking, the “repetition tempo” may be referred to as “walking tempo.”

In the case when the sensor 23a is provided with a global positioning system (GPS), the first exercise information obtaining section 22a obtains an exercise speed (e.g. exercise distance per minute) or an exercise pace (e.g. exercise time (minute) per km) based on a difference between values of position data from the GPS. This exercise speed is integrated with respect to time to obtain an exercise distance. Alternatively, the exercise speed may be obtained by multiplying a stride by a repetition tempo value.

In the case when the sensor 23a is provided with a heart rate sensor (heart rate meter or pulse rate meter), the first exercise information obtaining section 22a obtains a value of the heart rate from a beat timing signal. Additionally, the first exercise information obtaining section 22a can obtain exercise intensity of the first exercising person 1a based on the value of the heart rate.

The exercise intensity is calculated by the following formula:

The exercise intensity n [%]=(heart rate−resting heart rate)/(maximum heart rate−resting heart rate)×100;

where the maximum heart rate can be estimated with the formula: [220−age in years]. The age in years and the resting heart rate are stored in advance in an exercise-related-personal-information storage section 24a. Other than the aforementioned exercise information, a calorie consumption can also be calculated based on the type of exercise (walking, jogging, etc.), exercise speed, weight, and exercise time (see the “BF-11 Manual”).

The first exercise information obtaining section 22a obtains a value of the exercise information and supplies it to a repetition-notification-tempo specifying section (music-tempo specifying section) 25a in real time. When the first notification signal generation apparatus 2a operates in the “free workout mode” discussed in the description of BACKGROUND, the repetition-notification-tempo specifying section (music-tempo specifying section) 25a specifies a repetition notification tempo (music tempo) value that corresponds to a repetition tempo value of the first exercising person 1a to a notification signal generation controller (music production controller) 26a.

When the first notification signal generation apparatus 2a operates in the “fitness mode” discussed in the description of BACKGROUND, the repetition-notification-tempo specifying section 25a specifies a repetition notification tempo (music tempo) value to the notification signal generation controller (e.g., a music generation controller) 26a such that a heart rate value of the first exercising person 1a approximates a target heart rate value stored in the exercise-related-personal-information storage section 24a, in other words, such that the difference in value between the target heart rate and the heart rate of the first exercising person 1a is reduced. The notification signal generation controller 26a causes a notification signal generator (e.g., a music generation section) 28a to output a notification signal (music signal) with a repetition notification tempo (music tempo) value corresponding to the specified repetition notification tempo (music tempo) value to an electric acoustic converter, such as the earphone 6a shown in FIG. 1.

An apparatus that has the functions of the first exercise information obtaining section 22a, the repetition-notification-tempo specifying section 25a, and the notification signal generation controller 26a is equivalent to a notification signal control apparatus 27a. Operation of the first notification signal generation apparatus 2a, when serving as the first music playback apparatus, will be described later with reference to FIGS. 7A and 7B. It should be understood that when the second notification signal generation apparatus 2b operates in the dependent mode, the first exercising person 1a does not necessarily sense a notification signal. Thus, the functions of the repetition-notification-tempo specifying section 25a, the notification signal generation controller 26a, and the notification signal generator 28a may be disabled.

A value of the exercise information is obtained in the first exercise information obtaining section 22a and is then transferred in real time from a communication section 29a to the exercise information management center 9. The value of the exercise information is once stored in an exercise information storage device 30 at an area assigned to the first exercising person 1a.

It is assumed that in the second notification signal generation apparatus (music playback apparatus) 2b, an operation mode selection section 21b sets the “dependent mode” for a second exercise information obtaining section 22b. In the “dependent mode,” the second exercise information obtaining section 22b can also function as means for obtaining exercise information on another exercising person through a communication section 29b. More specifically, the second exercise information obtaining section 22a obtains a value of certain exercise information on the first exercising person 1a, which is acquired during the repetitive exercise performed by the first exercising person 1a and stored in the exercise information storage device 30 in the exercise information management center 9, through the communication section 29b in real time during the repetitive exercise performed by the first exercising person 1a. It should be understood that the second exercise information obtaining section 22b can also function as the aforementioned “own exercise information obtaining section.”

A repetition-notification-tempo specifying section (music-tempo specifying section) 25b specifies a repetition notification tempo value such that a value of certain exercise information on the second exercising person 1b approximates a value of the certain exercise information on the first exercising person 1a, which is obtained by the second exercise information obtaining section 22b for the second exercising person 1b, in other words, such that the difference in value of the certain exercise information between the first and second exercising persons 1a and 1b is reduced.

There are three specific approaches as described below.

(1) In the case when the exercise information is a repetition tempo, a repetition tempo value of the first exercising person 1a is specified directly as a repetition tempo value of the second exercising person 1b.

The repetition-notification-tempo specifying section (music-tempo specifying section) 25b specifies a repetition notification tempo (music tempo) value corresponding to the repetition tempo value of the first exercising person 1a. It is easy for the second exercising person 1b to perform repetitive exercise in synchronization with a repetition tempo that corresponds to the repetition notification tempo (music tempo) of the notification signal (music). The second exercising person 1b senses the notification signal with a repetition notification tempo value corresponding to the repetition tempo value of the first exercising person 1a. This allows the second exercising person 1b to follow the repetition tempo of the repetitive exercise performed by the first exercising person 1a, while performing repetitive exercise. It should be understood that even if the repetition notification tempo value does not coincide with the repetition tempo value of the first exercising person 1a, the music tempo can be sometimes easily synchronized with the repetition tempo in the case of setting a so-called “half tempo.” More specific operation in the approach 1 will be described later with reference to the music mode 3A in FIG. 7C.

(2) A value of exercise information is converted into a repetition notification tempo value.

The repetition-notification-tempo specifying section (music-tempo specifying section) 25b defines a value that coincides with the value of the certain exercise information on the first exercising person 1a as a value of the second exercising person 1b, and converts the value of the second exercising person 1b into a repetition tempo value of the second exercising person 1b to specify a repetition notification tempo (music tempo) value corresponding to the converted repetition tempo value.

(a) In the case when the exercise information is an exercise speed, the exercise speed of the first exercising person 1a is divided by the stride of the second exercising person 1b to be converted into a repetition tempo of the second exercising person 1b.

(b) In the case when the exercise information is an exercise distance, the following approach is taken as appropriate, but not always the case. The exercise distance of the first exercising person 1a is divided by an elapsed exercise time of the first exercising person 1a to obtain an average exercise speed of the first exercising person 1a. This average exercise speed is divided by the stride of the second exercising person 1b to be converted into a repetition tempo of the second exercising person 1b. In this case, the exercise information is substantially the average exercise speed.

(C) In the case when the exercise information is exercise intensity of an exercising person, the repetition-notification-tempo specifying section 25b defines a value that coincides with an exercise intensity value of the first exercising person 1a as an exercise intensity value of the second exercising person 1b, and estimates a repetition tempo value to result in the exercise intensity value of the second exercising person 1b based on his or her exercise-related personal information and past exercise results so that the exercise intensity is converted into a repetition tempo of the second exercising person 1b. The correlation of the repetition tempo value relative to the exercise intensity value may be predetermined in a form of a table.

More specific operation in the case (a) when the exercise information is an exercise speed will be described later with reference to the music mode 3B in FIG. 7D.

(3) Values of certain exercise information are compared between the first and second exercising persons 1a and 1b.

The second exercise information obtaining section 22b for the second exercising person 1b obtains a value of the certain exercise information on the first exercising person 1a in real time during the repetitive exercise performed by the first exercising person 1a, and concurrently obtains a value of the certain exercise information on the second exercising person 1b in real time during the repetitive exercise performed by the second exercising person 1b. The repetition-notification-tempo specifying section 25b compares the values on the certain exercise information between the first and second exercising persons 1a and 1b, and specifies a repetition notification tempo (music tempo) value such that the difference in value between the first and second exercising persons 1a and 1b is reduced.

A more specific case when a value of certain exercise information on an exercising person increases as his or her exercise intensity increases, and vice versa, is described below (although the description of the vice-versa case is omitted for redundancy).

(a) (value of exercise information on second exercising person 1b)<(value of exercise information on first exercising person 1a)

The repetition-notification-tempo specifying section (music-tempo specifying section) 25b specifies a repetition notification tempo value larger than the current repetition notification tempo value of the notification signal (generally equal to the currently-specified repetition notification tempo value). For example, the repetition notification tempo value is increased by 5%, compared to the current repetition notification tempo value of the notification signal.

(b) (value of exercise information on second exercising person 1b)>(value of exercise information on first exercising person 1a)

The repetition-notification-tempo specifying section 25b specifies a repetition notification tempo value smaller than the current repetition notification tempo value of the notification signal. For example, the repetition notification tempo value is decreased by 5%, compared to the current repetition notification tempo value of the notification signal.

In the aforementioned specific examples, the repetition notification tempo value is increased or decreased by a predetermined rate from the current repetition notification tempo value of the notification signal. However, the repetition notification tempo value may be increased or decreased by adding or subtracting a predetermined value to or from the current repetition notification tempo value.

According to the approach (3), the second exercising person 1b senses if the repetition notification tempo (music tempo) is faster or slower than the current tempo value. This helps the second exercising person 1b intuitively understand if the current value of the exercise information exceeds or falls below the value of the exercise information on the first exercising person 1a. Eventually, the repetition notification tempo value is kept approximately constant or kept in a stable state in which the value of the exercise information on the second exercising person 1b coincides with the value of the exercise information on the first exercising person 1a. This approach may also be applied to the case when the exercise information is a repetition tempo, in addition to the case when the exercise information is an exercise speed, an exercise distance, exercise intensity, or a calorie consumption.

In the case of sharing a repetition tempo between exercising persons according to the approach (1), the second exercising person 1b is not always performing repetitive exercise with a repetition tempo value close to the repetition tempo value of the first exercising person 1a at the current point in time. It is conceivable under this condition that even if the second exercising person 1b hears a notification signal with a repetition notification tempo value that coincides with the repetition tempo value of the first exercising person 1a, the difference between the repetition notification tempo value and the repetition tempo value of the second exercising person 1b is so large that the second exercising person 1b has difficulty in continuing the repetitive exercise. In contrast, according to the approach (3), even in the case when the exercise information is a repetition tempo, the first and second exercising persons 1a and 1b can share the repetition tempo through feedback including the information on the conditions of the repetitive exercise performed by the exercising persons.

In the case of sharing an exercise speed (exercise pace) between exercising persons according to the approach (2), the second exercising person 1b is not always performing repetitive exercise at an exercise speed close to the exercise speed of the first exercising person 1a at the current point in time. Otherwise the stride of the second exercising person 1b cannot be kept constant. It is conceivable under this condition that even if the second exercising person 1b hears a notification signal with a repetition notification tempo value that coincides with the repetition tempo value of the first exercising person 1a corresponding to his or her exercise speed value, the difference between the repetition notification tempo value and the repetition tempo value of the second exercising person 1b is so large that the second exercising person 1b has difficulty in continuing the repetitive exercise. In contrast, according to the approach (3), the first and second exercising persons 1a and 1b can share the exercise speed through feedback including the information on the conditions of the repetitive exercise performed by the exercising persons.

It should be understood that in the case when the exercise information to be shared between the exercising persons is other than the repetition tempo, a repetition notification tempo value does not always coincide with a repetition tempo value of the actual repetitive exercise even in the aforementioned stable state. For such a case, the second notification signal generation apparatus 2b may be provided with a “tempo-up switch” and a “tempo-down switch.” The second exercising person 1b operates this switch to control the repetition notification tempo value to coincide with or approximately coincide with the repetition tempo value of the second exercising person 1b in the stable state. This helps the second exercising person 1b easily continue the repetitive exercise.

A notification signal generation controller (e.g., a music generation controller) 26b and a notification signal generator (e.g., a music generation section) 28b are respectively identical to the notification signal generation controller (music generation controller) 26a and the notification signal generation section (music generation section) 28a that are described above. The notification signal generator (music generation section) 28b outputs a notification signal (music signal) with a repetition notification tempo (music tempo) value corresponding to the specified repetition notification tempo (music tempo) value to the earphone 6b shown in FIG. 1.

In the comparison approach (3), the repetition-notification-tempo specifying section 25b compares values of certain exercise information between the first and second exercising persons 1a and 1b. If the value of the second exercising person 1b deviates from the value of the first exercising person 1a by a predetermined amount (predetermined value or predetermined rate relative to the value of the first exercising person 1a) or more, the second exercising person 1b may be notified of the deviation with a special notification signal (warning signal). In this case, it is desirable that the warning signal allows the second exercising person 1b to sense whether the “deviation” results from the slower repetition tempo or the faster repetition tempo of the repetitive exercise. Such a notification signal may be a notification sound or synthetic voice distinguishable from the original notification sound designed to match the repetition tempo or may be a notification light or character display distinguishable from the original notification light designed to match the repetition tempo.

The warning notification may also be provided in the approaches (1) and (2), if the value of the second exercising person 1b deviates from the value of the first exercising person 1a by a predetermined amount (predetermined value or predetermined rate relative to the value of the first exercising person 1a) or more. The warning notification may include whether the deviation results from the faster or slower repetition tempo of the repetitive exercise.

In any of the approaches (1), (2), and (3), if a repetition tempo value of the actual repetitive exercise deviates from the current repetition notification tempo value by a predetermined amount (predetermined value or predetermined rate relative to the current repetition notification tempo value) or more, a warning notification of the deviation, including whether the deviation results from the faster or slower repetition tempo of the repetitive exercise, may be provided in a display mode either the same as or different from the display mode of the aforementioned warning notification.

It should be understood that there may be a plural number of the second exercising persons 1b (plural persons). The exercise information management center 9 may supply a value of exercise information on the first exercising person 1a to the plural second exercising persons 1b (not shown).

In the above description, a value of exercise information on the first exercising person 1a is supplied to the second exercising person 1b. However, a value of the exercise information on the second exercising person 1b may also be supplied to the first exercising person 1a simultaneously. In this case, the first notification signal generation apparatus 2a outputs a notification signal to the first exercising person 1a such that he or she performs repetitive exercise to have the value of his or her exercise information to coincide with the value of the exercise information on the second exercising person 1b. This allows the first and second exercising persons 1a and 1b to share the values of their partner's exercise information with each other as a target value to perform the repetitive exercise.

Therefore, among two or more exercising persons, the second exercising person 1b can select any of the other exercising persons as a target first exercising person 1a. Further, the second exercising person 1b can select any of plural kinds of exercise information, obtain a value of the selected kind of the exercise information, and set the obtained value as a target value. This allows the exercising person to specify a target exercising person that fits his or her program and do training based on his or her preferred exercise information.

FIG. 3 is a hardware configuration diagram to achieve the embodiment of the invention. This hardware apparatus has a function of connecting to the communication network through the wireless channel, a function of producing music, and individual sensors. In FIG. 3, a reference numeral 41 denotes a signal processor (central processing unit (CPU)). Peripheral functional blocks are connected to the CPU 41. A timer 42 is used as the timing reference for the main processing and interrupt processing in the CPU 41, or used as the time reference for a calendar function (year: month: day: hour: minute: second).

A memory 43 includes a Random Access Memory (RAM) and a flash Read Only Memory (ROM). The memory 43 stores an operating system program, various application programs, setting data, music data (Musical Instrument Digital Interface (MIDI) format and/or MPEG-1 Audio Layer-III (MP3) format or other wave formats), a music information database (reference number, music tempo, etc.), performance pattern part data and template data, and a telephone number list, for example.

A sound source section 44 has functions of producing an incoming-call sound of a mobile phone and various informing sounds, automatically playing the performance data in the MIDI format, and automatically creating music. A code/decode (CODEC) 45 encodes and decodes an analog signal. For example, in the case when a sound signal is the data in the MP3 format, the CODEC 45 compresses the data into a MP3 file and also decodes the MP3 file into a WAV file. A speaker or an earphone 46 outputs a sound signal or a music sound signal. A microphone 47 inputs a sound signal. The speaker or earphone 46 and the microphone 47 both are connected to the CPU 41 through the CODEC 45. A reference numeral 48 denotes a display. An operation panel 49 includes a transparent touch panel placed over the display 48 and mechanical contact switches.

A transmission/reception section 50 is designed to connect to the mobile phone network. An antenna 51 is connected to the transmission/reception section 50. A wireless LAN transmission/reception section 52 (its antenna is not shown) operates in accordance with the Wi-Fi, Bluetooth, or other standard. Reference numerals 53 and 54 respectively denote an acceleration sensor and a GPS sensor (its antenna is not shown). The acceleration sensor 53 detects a repetition tempo of repetitive exercise. The GPS sensor 54 detects position information, such as longitude and latitude. A heart rate sensor detects a heart rate (pulse rate) and transmits the detected heart rate waves or heart rate data to the CPU 41 through the Bluetooth in the wireless LAN transmission/reception section 52.

The functions of the notification signal control apparatuses 27a and 27b shown in FIG. 2 are achieved by the CPU 41′ by executing the program stored in the memory 43. The functions of the notification signal generators 28a and 28b shown in FIG. 2 are achieved by the sound source section 44 and the CODEC 45 by using music or other data stored in the memory 43. The notification signal controllers 27a and 27b and the notification signal generators 28a and 28b may be formed into separate, devices that are physically away from each other.

FIG. 4 is a flowchart that principally illustrates an operation for controlling a notification signal as part of the operations to be performed in the CPU 41 in FIG. 3. The power source is switched-ON to start the processing and perform initialization at step S61. The CPU 41 receives user's operation and performs processing of the application program (FIG. 5A) at step S62, and then performs processing for telephone communication at step S63. If there is an incoming call, an incoming call sound is output even during the execution of the application program to allow a user to have a conversation through the user's operation. A phone call is made upon the user's operation. The CPU 41 returns the processing to the step S62 from the step S63 to repeat the processing until the power is turned off.

FIG. 5A is a flowchart of a routine to execute an application program. The application program that embodies the present invention is for example named “combining exercise and music.” At step S71, if the user operates or selects the “combining exercise and music” program, the CPU 41 starts-up the “combining exercise and music” program and advances the processing to step S74. If the “combining exercise and music” program has already started-up, the CPU 41 also advances the processing to the step S74. In other cases, the CPU 41 performs processing for other application programs at steps S76 and S77 in the same manner as described above. The CPU 41 sets the “combining exercise and music” program (FIG. 5B) at the step S74, and executes the “combining exercise and music” program (FIG. 6) at step S75.

FIG. 5B is a flowchart to perform processing for setting the “combining exercise and music” program at the step S74 in FIG. 5A. At step S81, a screen of the current processing is displayed. A screen designed to receive a setting input from the user is first displayed. Subsequently a screen designed to display various information obtained during outputting the music and the repetitive exercise is displayed.

At step S82, the apparatus of the invention (the first notification signal generation apparatus 2a or the second notification signal generation apparatus 2b) is connected to the exercise information management center (hereinafter referred to as server) 9 to receive data transmitted from the server 9 or transmit data to the server 9, if necessary.

The data received from or transmitted to the server 9 includes exercise information, exercise selection information (e.g. running/jogging/walking), music mode, exercise time, exercise conditions such as exercise distance, exercise performance results (ranking and record), and other information.

At step S83, if data is input through the user's operation, the CPU 41 receives the input data, and performs setting of the apparatus of the invention based on the input data. The input data that needs to be transmitted to the server 9 is temporally held, and is then transmitted to the server 9 later when the processing goes through the flowchart and comes back to step S82.

At step S85, if any of the modes is selected through the user's operation, the CPU 41 performs the mode setting. For example, the CPU 41 sets the music mode or sets the selected exercise and exercise conditions. At step S87, if the user provides an instruction to start the program, the CPU 41 sets a start flag for the preset music mode. In the subsequent processing, whether the processing is being performed is determined depending on whether the start flag is set.

At step S89, if the user provides an instruction to stop the program through the user's operation, the CPU 41 clears the start flag for the preset music mode. At step S91, the CPU 41 performs processing in response to any other instruction from the user.

FIG. 6A is a flowchart to perform processing for executing the “combining exercise and music” program at the step S75 in FIG. 5A. If the start flag has been already set for the “combining exercise and music” program in the previous step S88, the CPU 41 advances the processing from step S101 to either one of the steps for the music modes 1, 2, 3A, and 3B according to the music mode that has been preset in the previous step S86.

FIG. 6B is a flowchart of a routine to perform interrupt processing in parallel with the processing according to the main flowchart in FIG. 4. The interrupt processing starts-up with a short time interval. Exercise information on a person him or herself (e.g. second exercising person 1b) and exercise information on another person (e.g. first exercising person 1a) are obtained by the interrupt processing.

If the start flag has been already set for the “combining exercise and music” program in the previous step S88, the CPU 41 advances the processing from the step S111 to its subsequent steps.

At step S112, if the acceleration sensor 53 (FIG. 3) detects any impact, the CPU 41 goes to steps S113 to S115. The CPU 41 obtains an elapsed time from a timer A, and calculates a repetition tempo value based on the moving average of the elapsed time. The CPU 41 then resets the timer A to start counting the elapsed time again.

At step S116, if a heart rate is detected, the CPU 41 calculates a value of the heart rate at steps S117 to S119 in the same manner as at steps S113 to S115. The exercise intensity is calculated based on the heart rate.

At step S120, if there are variations in the latitude-longitude (position) data that is output from the GPS sensor 54, the CPU 41 calculates the travel of the exercising person from the previous position at step S121 based on the difference between the current position data and the previously-obtained position data that has been obtained in the previous processing step S122, and updates the position data that indicates the current position at step S122. The travel of the exercising person from the previous position is divided by the difference between the previous point in time and the current point in time to calculate the exercise speed. In addition, the travels thus obtained during the period from the exercise starting point in time to the current point in time are added together to calculate the exercise distance from the exercise starting point to the current location during the above period. Alternatively, the aforementioned exercise speed may be integrated with respect to time from the exercise starting point in time to the current point in time to calculate the exercise distance as described above.

If either one of the values of the exercise information, including the repetition tempo, heart rate (exercise intensity), and exercise speed (and exercise distance), is calculated at step S123, the calculated value, together with the current point in time or the elapsed time from the previous calculation, are recorded in the internal memory and concurrently transmitted to the server 9, and then transmitted through the server 9 to an exercising person who exercises simultaneously (and/or may be recorded in the storage device 30 in the server 9) at step S124. It should be understood that exercising persons have different heart rate values depending on their athletic abilities and other abilities. Therefore, the heart rate values are converted into exercise intensity, a common indicator among the exercising persons, to be transmitted.

The second notification signal generation apparatus 2b for the second exercising person 1b in the dependent mode, as shown in FIG. 2, needs to obtain exercise information on another exercising person. In such a case of obtaining exercise information on another exercising person in real time, the CPU 41 advances the processing from S125 to S126 to receive the exercise information on the other exercising person via the server 9, and then advances the processing to step S127 to obtain a value of the exercise information on the other exercising person.

In contrast, exercise results (sequence data of variable exercise information relative to the elapsed time or exercise distance) of an exercising person him or herself are saved in the memory 43 of the apparatus of the invention by the recording processing at step S124. In addition, exercise results of another exercising person are saved in the exercise information storage device 30 in the server 9. The past exercise results of another exercising person may be downloaded to the memory 43 (FIG. 3) from the server 9 prior to starting exercise. Thus, an additional function (playback) may be provided to sequentially read the exercise information on the exercising person him or herself or the exercise information on the other exercising person, which are stored in the memory 43. If the playback function is used, the CPU 41 advances the processing from step S128 to step S129 to read the exercise result file saved in the memory 43, and obtains a value of the exercise information on the other exercising person (including the past exercise information on the exercising person him or herself) at step S127.

It should be understood that as a modification example for step S128, the exercise results of the other exercising person may also be received from the exercise information storage device 30 in the server 9 at each time when the exercise information is generated (at event timing), as if the exercising person receives the exercise information in real time.

FIGS. 7A to 7D are flowcharts that illustrate processing in the respective music modes in FIG. 6A. FIG. 7A is a flowchart that illustrates operation in the “music mode 1.” This mode corresponds to the “free workout mode” discussed in the description of BACKGROUND and is designed to output music with a music tempo that matches the repetition tempo of the exercising person's running.

At step S131, if there is new “record/transmit” processing at step S124 in FIG. 6B, the CPU 41 goes to step S132 to perform the following processing. If the “recorded exercise information” is the “repetition tempo value” obtained at step S114 and this “repetition tempo value” is varied by a predetermined amount (predetermined rate or predetermined difference) or more from the current “repetition tempo value,” the CPU 41 advances the processing to step S134.

It should be understood that in the case when the notification information is music and the music is selected from plural pieces of music stored in the storage device, if there is no music stored in the memory 43 with a specified music tempo value, the CPU 41 selects music with a tempo value close to the specified music tempo value at step S135 that will be described later. Thus, at step S136 that will be described later, a music tempo value of the currently-output music does not always coincide with the currently-specified music tempo value at the step S134. Therefore, the “music tempo value” of the currently-output music (however, if the music is output by setting to “half tempo,” the music tempo is twice as fast as the “half tempo”) is more preferably used as the current “repetition tempo value,” instead of using the currently-specified music tempo value.

At the step S134, the CPU 41 additionally specifies the varied repetition tempo value as a music tempo value.

At the step S135, an additional music piece is selected or produced as followings.

(1) In the case of selecting an additional music piece, any music with a music tempo value that is the same as or close to the additionally-specified music tempo value is selected from plural pieces of music stored in the memory 43 in FIG. 3. The selected music is loaded to a cache memory (included in the memory 43 in FIG. 3).

(2) In the case of automatically producing an additional music piece (see Japanese Patent Publication No. 4306754 (JP 4306754B), for example).

In the case of automatically producing an additional music piece, the performance pattern part data and template data stored in the memory 43 in FIG. 3 are used to automatically produce a music piece with a music tempo value that is the same as the additionally-specified music tempo value. Data of the produced music piece is loaded to the cache memory.

The music loaded to the cache memory is output at the step S136. If there is no new “record/transmit” processing at the step S131 or the “repetition tempo value” does not meet the predetermined condition at the step S132, the CPU 41 advances the processing to the step S133. In this step, if the current music data output is completed (the music song ends), the CPU 41 advances the processing to the step S134. At this time, at the step S134, the specified music tempo value remains unchanged. In contrast, if the current music data output is not completed yet (in the middle of playing the music song), the CPU 41 advances the processing to the step S136.

It should be understood that when the processing is advanced to the step S134 via the step S133, if the “repetition tempo value” is varied by a smaller predetermined amount (smaller predetermined rate or smaller predetermined difference) or more, compared the “predetermined amount” at the step S132, the CPU 41 may additionally specify this varied “repetition tempo value” as a music tempo value.

FIG. 7B is a flowchart that illustrates operation in the “music mode 2.” This mode corresponds to the “fitness mode” discussed in the description of BACKGROUND and is designed to specify a music tempo value such that the user's heart rate reaches a “target heart rate,” and to output music with the specified tempo value. The “target heart rate” has been preset in the exercise program. It should be understood that the “target heart rate” and the “heart rate” can be converted into “target exercise intensity” and “exercise intensity.”

At step S141, if there is new “record/transmit” processing at the step S124 in FIG. 6B, the CPU 41 goes to step S142 to perform the following processing. If the “recorded exercise information” is the “heart rate value” that is obtained at the step S118 and that falls out of a predetermined range of the current “target heart rate value” (target heart rate value±predetermined ratio or±predetermined difference), the CPU 41 advances the processing to step S144.

At the step S144, if the obtained “heart rate value” is larger than the “target heart rate value,” the CPU 41 additionally specifies a music tempo value that is smaller (e.g. decreased by 5%) than the music tempo value of the currently-output music. In contrast, if the obtained “heart rate value” is smaller than the “target heart rate value,” the CPU 41 additionally specifies a music tempo value that is larger (e.g. increased by 5%) than the music tempo value of the currently-output music.

At step S145, music is additionally selected or produced, and is loaded to the cache memory. The music loaded to the cache memory is output at step S146.

As described for the step S136 in FIG. 7A, at the step S146, a music tempo value of the currently-output music does not always coincide with the currently-specified music tempo value at the step S144. Thus, at the step S144, desirably the determination is made based on the “music tempo value of the currently-output music”.

If there is no new “record/transmit” processing at the step S141 or the “heart rate value” does not meet the predetermined condition at the step S142, the CPU 41 advances the processing to the step S143 to perform the same processing as at the step S133 in FIG. 7A. In other words, the processing is advanced to the following step S144. At this time, at the step S144, the specified music tempo value remains unchanged. In contrast, if the current music data output is not completed yet (in the middle of playing the music song), the CPU 41 advances the processing to the step S146. The music tempo value thus specified allows the heart rate value to be controlled to fall within the range of the target heart rate.

It should be understood that when the processing is advanced to the step S144 via the step S143, the CPU 41 determines whether the “heart rate value” is varied over a smaller “predetermined range” (target heart rate value±smaller predetermined ratio or±smaller predetermined difference) than the “predetermined range” at the step S142. If the determination is affirmative, the CPU 41 may specify a music tempo value in exactly the same manner as when the processing is advanced to the step. S144 via the step S142.

FIG. 7C is a flowchart that illustrates operation in the “music mode 3A.” This mode is designed to output music with a music tempo value that is the same as the repetition tempo value of another exercising person (first exercising person 1a) so that the exercising person can perform the repetitive exercise with the same repetition tempo value as the other exercising person.

In the case when the value of the exercise information on the other exercising person, which is obtained at the step S127 in FIG. 6B, is a repetition tempo value obtained in real time at the step S126, if this repetition tempo value is varied from the current value by a predetermined amount (predetermined ratio or predetermined value) or more at step S152, the CPU 41 advances the processing to step S154. At the step S154, the CPU 41 additionally specifies the varied repetition tempo value as a music tempo value. Similar to the step S132 in FIG. 7A, when music is selected from plural pieces of music stored in the storage device, the “music tempo value of the currently-output music” is used preferably as the “current value” of the repetition tempo. The processing at steps S155, S156, and S153 is performed in the same manner as the processing at the steps S135, S136, and S133 in FIG. 7A, respectively.

FIG. 7D is a flowchart that illustrates operation in the “music mode 3B.” This mode is designed to output music with a music tempo value that is the same as the repetition tempo value converted from the exercise speed, so that the exercising person can perform repetitive exercise at the same exercise speed as the other exercising person.

The processing at steps S161 and S162 is performed in the same manner as the processing at the steps S151 and S152 in FIG. 7C, respectively. At step S164, a value of the varied exercise speed is divided by a stride to obtain a repetition tempo value, and the CPU 41 additionally specifies the obtained repetition tempo value as a music tempo value. The processing at steps S163 to S166 is performed in the same manner as the processing at steps S153 to S156 in FIG. 7C, respectively.

At the step S155 in FIG. 7C when music is selected by specifying the music tempo value, the output music (hereinafter more specifically referred to as music song) can be the same as the music song to be output for the other exercising person. This helps the exercising person feel more togetherness with the other exercising person. Thus, not only the exercise information, but also other information required for identifying the music song to be output for the other exercising person, such an a reference number of the music song, may also be supplied from the other exercising person to the exercising person via the server.

In this case, if the same music song is also stored in the storage device for the exercising person, this same music song is output, or if the same music song is not stored, an alternative music song with a music tempo value that coincides with or approximately coincides with the specified value may be output. It should be understood that the exercising person may select a music song from his or her favorite music songs stored in the storage device for him or her, independently from the music song to be output for the other exercising person.

The approach (3) in which “values of certain exercise information are compared between the first and second exercising persons 1a and 1b” is now additionally described, although it has been already described with reference to FIG. 2. In order to more specifically carry out this approach, the “target heart rate” value at the step S142 in FIG. 7B may be replaced with a value of certain exercise information on another exercising person (first exercising person 1a), while the “heart rate” value may be replaced with a value of the certain exercise information on an exercising person him or herself (second exercising person 1b).

FIG. 8 is a flowchart to perform processing in the server connected to the communication network. After step S171 for initialization, the processing of following steps S172-S179 is repeated.

At step S172, the server 9 is on standby until an individual exercising person (hereinafter referred to as user), a membership of the “combining exercise and music” application program, requests for connection to the server. Upon a connection request from any one of the individual users, the server 9 receives an input of user ID and password to authenticate the user at step S174.

If the user is not authenticated, the server 9 performs processing for canceling the request for connection to the server at step S179. If the user is authenticated, the server 9 creates display screen data associated with the individual user and transmits the display screen data to the notification signal generation apparatus for the authenticated user at step S175. An initial display screen shows the service menu selection available for the authenticated user.

At step S176, the server 9 receives data transmitted from the user. For example, the data transmission includes a real-time request for the exercise information on another user during his or her repetitive exercise, a request transmitted from the user who makes a selection on the display screen, a request input by letters transmitted from the user, a real-time supply of the exercise information on the user during his or her repetitive exercise, a supply of a file containing the exercise results from the exercise performed, and supplies of the exercise history, the output music history, and so forth.

At step S177, the server 9 performs various processing. Upon receipt of a request from the user, the server 9 performs processing in response to the request. Upon a request for suggested music, the server 9 selects music with a music tempo that matches the user's personal information and exercise history, creates a music list to be presented to the user, and prepares for downloading the music. The exercise information on the user during his or her repetitive exercise is stored in the exercise information storage device 30.

The exercise information on the other user during his or her repetitive exercise, the music list, and the music can be provided to the user at the step S175 of the subsequent processing, if necessary.

The server 9 can distribute the exercise information on a single user (e.g. first exercising person 1a) in real time to the second notification signal generation apparatuses 2b for plural users (e.g. second exercising persons 1b).

The first exercising person 1a can decide who can utilize his or her exercise information. For example, the first exercising person 1a can perform setting to permit anyone to utilize his or her exercise information, or permit only a user in a specific group or a specific user to utilize his or her exercise information, or not to permit anyone to utilize his or her exercise information.

Upon receipt of the exercise history or the music playback history, the server 9 analyzes which music the user preferably listens to under which physical conditions (exercise-related personal information). Moreover, the server 9 compiles the exercise history and the music playback history of the user with the exercise history and the music playback history of the other user to find the user's relative statistical values and preferences, and stores this information as user's personal data. This helps the server 9 provide services that match the user's statistical values and preferences.

If the user transmits “termination request” data at step S178, the server 9 performs processing for canceling the connection to the server at step S179. The server 9 returns the processing to the step S172 to wait for another request from the user for connection to the server.

FIGS. 9A and 9B illustrate specific examples to which the embodiment of the invention is applied. The embodiment of the invention is provided as services to mobile terminals, such as smart phones. A repetition tempo value is detected based on an output from the acceleration sensor built in the mobile terminal. The “combining exercise and music” program is an application program to be executed by using one of the functions of the application program “GAME CENTER (trademark)” preinstalled in the “iPhone (registered trademark) 4G”, one of the smart phones. Sharing a repetition tempo value between plural exercising persons and communication are achieved by the function “Multi Player Game” of the “Game Center (trademark).”

FIG. 9A illustrates a screen for the user on which the user's nickname “TORU” is displayed. On this screen, reference numerals 181, 182, 183, and 184 respectively denote a smart-phone housing, a touch panel screen, a switch, and a speaker. On the illustrated touch panel screen 182, a “combining exercise and music” display 185 is provided. Tapping the display 185 allows the “combining exercise and music” application program to start.

On a setting start screen (not shown), the user enters the “combining exercise and music” program via the server 9 on the communication network 8, and selects friends whom the user desires to exercise together (group members who exercise together) as well as specifies a target person (named a “pace maker”), from whom the user obtains target exercise information, among the group members. In other words, the target person is a member (exercising person) or a coach (exercising person) whom the user desires to follow the example for the repetitive exercise.

If one of the exercising persons, who is selected by the user as a member, has already started exercising, the member selection screen displays values of one or more kinds of the current exercise information on the selected member, such as repetition tempo value and exercise distance (running distance) value, in real time. If one of the exercising persons, who is selected by the user as a member, has not yet started exercising, the member selection screen displays values of one or more kinds of the past exercise information on the selected member, which are read from his or her history. Desirably, the user's own exercise information is also displayed in the same manner. This allows the user to select a partner that fits the user's exercise goal and athletic level and to share the exercise information with the selected partner. The user can select target exercise information among plural kinds of exercise information.

While viewing the display screen described above, the user can cancel the selection of the member who has been selected once or can make the user him or herself outside the group. Even after the user starts exercising by selecting the member, the user can switch the display screen to the member selection screen to know the exercise conditions of the other members in real time.

FIG. 9B illustrates a screen to start executing the “combining exercise and music” program. A reference numeral 191 denotes a display of a timer that measures time (hour: minute: second). Reference numerals 192, 193a, 193b, 194a, and 194b respectively denote a start button, a pace-maker member's repetition-tempo display, a user's (own) repetition-tempo display, a user's (own) running distance (exercise distance), and a user's (own) calorie consumption. In the illustrated example, the repetition tempo is selected as a target. An additional area may be provided to display values of common exercise information on the pace-maker member and the user.

The user taps the start button 192 to start executing the program. On a touch panel screen 182 in FIG. 9B, a displayed numerical value is varied. Simultaneously, a repetition tempo value of the pace-maker exercising person is obtained through the server 9 to output music with a music tempo value corresponding to the obtained repetition tempo value. The software sound source (software synthesizer) installed in the “combining exercise and music” application program is used to automatically produce music with the corresponding music tempo. This music is output from the speaker 184 or the external earphone.

As described above, when a certain exercising person (e.g. second exercising person 1b) finishes exercising, the sequence data of the exercise information (values of the exercise information relative to the elapsed time or elapsed travel distance) on the second exercising person 1b is saved in the memory 43 in the second notification signal generation apparatus 2b (the step S124 in FIG. 68) or is stored in the exercise information storage device in the exercise information management center (server) 9 (the step S177 in FIG. 8) as the exercise results.

After finishing exercising, the second exercising person 1b views the aforementioned exercise results on the display screen or the like to compare the exercise results among the plural exercising persons or with the other exercising person and review the exercise. At this time, the exercise information management center (server) 9 automatically performs the comparison processing so that the second notification signal generation apparatus 2b can make evaluations on the exercise results (with score or ranking). The exercise results recorded in the memory 43 in the second notification signal generation apparatus 2b may be uploaded to the exercise information management center (server) 9 after the exercise is finished. The exercise results stored in the exercise information management center (server) 9 are compared with the exercise results of the other exercising persons for ranking. The exercise results thus stored may also be utilized by the other exercising persons.

In the case when the second notification signal generation apparatus (music playback apparatus) 2b reads music with a specified repetition notification tempo (music tempo) from plural pieces of music stored in a storage device to output the music in FIG. 2, the storage device is built in the notification signal generator (music generation section) 28b. In this case, the first notification signal generation apparatus (music playback apparatus) 2a may supply a reference number to identify the music together with the exercise information.

There is a case when a “repetition tempo” value is shared as the exercise information, and a repetition notification tempo (music tempo) is specified corresponding to the “repetition tempo” value. In this case, if music data associated with the supplied reference number is stored in the storage device built in the notification signal generator (music generation section) 28b, the second notification signal generation apparatus (music playback apparatus) 2b can output the music data. This allows the first and second exercising persons 1a and 1b to share the music data as well. However, if any music data associated with the supplied reference number is not stored in the storage device built in the notification signal generator (music generation section) 28b, music data with a music tempo value according to the specified music tempo value may be selected from plural pieces of music data stored in a repetition notification tempo storage device, so that the second notification signal generation apparatus 2b may output the selected music data.

Alternatively, the streaming reproduction technology or other technology may be used to supply the music data from the first notification signal generation apparatus (music playback apparatus) 2a via the exercise information management center 9 and the communication network 8 to the second notification signal generation apparatus (music playback apparatus) 2b to output the music data. Further alternatively, plural pieces of music data may be shared in advance between the first notification signal generation apparatus (music playback apparatus) 2a and the second notification signal generation apparatus (music playback apparatus) 2b. It should be understood that the communication network 8 is not limited to the Internet, but may be any wireless or wired network. In addition, the server 9 may be omitted so that the exercise information on the first exercising person 1a can be directly supplied to the second notification signal generation apparatus (music playback apparatus) 2b for the second exercising person 1b.

This application is based on, and claims priority to, JP PA 2011-035606 filed on 22 Feb. 2011. The disclosure of the priority application, in its entirety, including the drawings, claims, and the specification thereof, are incorporated herein by reference.
