Abstract: A designation unit designates a checkpoint of sporting equipment on which a swing motion is performed. A first calculation unit calculates a movement path of the sporting equipment, which is being swung, using an output of an inertial sensor. A second calculation unit calculates a posture of an interest part of the sporting equipment at the checkpoint using the output of the inertial sensor up to the checkpoint on the movement path of the sporting equipment. The display unit displays the posture of the interest part of the sporting equipment at the checkpoint.

Abstract: A motion analysis method includes: specifying plural operations included in a motion operation using an output from an inertial sensor; calculating an operating time of each of the plural operations; adjusting a time axis of each operating time; and outputting operation information of the operation based on the adjusted time axis.

Abstract: A motion detection device specifies a movement of at least one of a subject and a sporting gear as an indicator of a trigger signal, using an output from an inertial sensor. The movement of at least one of the subject and the sporting gear is specified in the output from the inertial sensor. The trigger signal is generated according to the specified movement. The subject causes the trigger signal to be generated at proper timing through his or her own movement.

Abstract: In a motion analysis device, a first detection section detects a first state of a shaft portion of sporting equipment using an output of an inertial sensor. The first state corresponds to, for example, a resting state. A second detection section detects a second state of the shaft portion of the sporting equipment using the output of the inertial sensor. The second state corresponds to, for example, an impact. The second detection section detects a relative rotational angle of the shaft portion having varied around an axis of the shaft portion from the first state.

Abstract: In a motion analysis method, an impact point analysis section identifies a posture of a hitting area of sporting equipment at impact using an output of an inertial sensor. A determination section determines a type of a course of a hit ball using information of the posture of the hitting area thus identified. The course of the hit ball is estimated with the posture of the hitting area at impact. The type of the course of the hit ball is determined in accordance with the posture of the hitting area.

Abstract: A motion analysis method includes calculating a change in an amount of inertia of a region attached with an inertial sensor during a swing using an output of the inertial sensor, and identifying a maximum value of the amount of inertia during the swing to compare the maximum value and the amount of inertia at an impact with each other. A deceleration timing during the swing of the region (the grip of the sporting equipment) attached with the inertial sensor is identified, and the quality of the swing can be evaluated.

Abstract: A blank oscillator 300? is prepared for each office, and control data is written into this blank oscillator 300?, thereby manufacturing an oscillator 300. Upon receiving an order from a user terminal 10, a business center server 100 selects the most suitable office for the delivery of the oscillator and sends the data to the office. A data writing apparatus 200 installed in this office generates control data based on the data, and writes the control data into the blank oscillator 300?, thereby manufacturing the oscillator 300.
