Interactive Doll

Abstract

A baby doll has a head, a body, and a display on the surface of the body. The display controllably displays a plurality of different images. Each image depicts an action to be taken with the baby doll. A plurality of sensors are located in the head or body. The sensors detect when a depicted action is taken with the baby doll, and the subsequent display or sounds of the baby doll depends on whether or not the sensors sense that the action depicted by the image displayed on the display is taken within a period of time after the image is displayed on the display.

Description

RELATED APPLICATION

This application claims the priority benefit of U.S. Provisional Application No. 60/884,840 filed on Jan. 12, 2007, which is hereby incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to dolls. More specifically, the present invention relates to dolls with electronics that provide for human interaction when playing with the doll.

2. Background of the Related Art

Dolls provide enjoyment for boys and girls. The Baby Needs Me doll from Kenner included a watch for the user of a baby doll. When the user pressed the button on the watch, it beeped and showed what the baby doll needed. The user was then to play along, and then provide the baby doll what it needed (e.g., a diaper change, a bottle, etc.). However, the interaction was merely prompted and whether it was performed or not was without consequence and realistic interaction.

It has become popular to include electronics and other parts in dolls that provide or mimic interaction between the doll and a boy or girl playing with the doll. Perhaps the most popular example of such an interactive doll was the Tickle Me Elmo doll. The popular Toddler Tabitha doll from MGA Entertainment had voice interaction, feeding and crawling/walking. The user needed to follow voice cues for the doll, and the user needed to be relatively older than an infant.

But it can be expensive or difficult to provide realistic interaction in dolls. Other more simple methods of interaction would be desirable. The interaction with simple games, such as Tamagotchi, is simple and simulates the nurturing and development of a simulated character. However, Tamagotchi games are encased in pocket sized plastic cases, similar to handheld LCD games, and so do not directly represent or mimic the baby doll or other character being nurtured.

BRIEF SUMMARY

The preferred embodiments of the invention are in the form of a doll as an interactive baby character with a display screen located on the chest. The display screen preferably is depicted as the heart of the baby. The doll includes multiple sensors for light, sound, and basic buttons for interaction. The doll may also include sensors which sense when objects come into contact with the baby doll.

The game play consists of the display screen displaying a desired input action on the display screen heart of the baby doll, and the user providing the displayed input. If the user fails to provide the desired input within a short amount of time, the doll will respond. For example, the doll will cry and then eventually go to sleep. The doll interacts with several matched accessories, such as a bottle, rattle, and blanket.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to several aspects of preferred embodiments of the invention that are illustrated in the accompanying drawings. The words “connect,” “couple,” and similar terms with their inflectional morphemes do not necessarily denote direct and immediate connections, but also include connections through mediate elements or devices.

The preferred embodiments of the invention involve a baby doll 100 that directs a child to various caretaking responsibilities as shown in FIG. 1. However, in other embodiments, the doll may represent other characters such as a teddy bear, dog, cat or other pet.

The various caretaking responsibilities of the preferred embodiments include feeding, burping, playing with a rattle or other toy, changing the baby's diaper, singing a lullaby, etc., although other actions can also be implemented. There may be over a dozen different functions so as to provide a good imitation of a baby. Additional activities may be child games such a Pat A Cake, Itsy bitsy Spider and Peek A Boo.

The baby doll 100 of the preferred embodiments may of any general construction. For example, the head, hands and feet of the baby doll may be made of PVC or other material, while the body of the baby is of an appropriate soft material and includes exterior clothing.

A display device 110 is provided in the body of the baby doll as shown in FIGS. 1 and 2. It includes a display element 111, such as a liquid crystal display, built into the body of the baby doll. The display device 110 preferably includes a heart shaped display or presents a heart shaped visual effect, such as by providing a heart-shaped plate 112 surrounding a rectangular display element 111. The display element 111 need not be a liquid crystal display and may be any suitable type of display element. There may also be two tactile switches SW1 and SW2 (which may take the forms of rubber buttons, pin, or other user input) on display device 110 which may be easily pressed by a child. Switch SW1 turns the power, for the display and other parts of the doll, on and off. It may also be operated to awaken the baby doll from a standby or “sleep” mode. Switch SW2 may also be operated to awaken the baby doll from the standby or “sleep” mode, to bypass a depicted action, or to play music. Display device 110 also includes a microphone M1 which is used with a sound sensor to detect sounds such as the child reading, singing or playing patty cake with the baby doll. Although shown as simple buttons in FIG. 2, switches SW1 and SW2 may be incorporated into, or be part of, displate plate 112. There may be a further button, pin or other device (not shown), which when pressed, changes the volume or performs some other function of the baby doll. Preferably, the display device 110 is configured so that the display element 111, switch SW1 and switch SW2 extend above the clothing of the baby doll 100. The clothing preferably fits under the plate 112 and covers the remainder of the display device 110, including microphone M1, so that they are hidden from view.

As shown in FIGS. 2 and 3, the inward side of the display device 110 supports the electronics used for controlling the operations of the baby doll 100. These electronics are connected by wires to a plurality of sensors. In the case of the preferred embodiment shown in FIGS. 1-3, there are three sensors. A contact sensor SW3 is located near the mouth and is used to detect a feeding action. A contact sensor SW4 is located near the baby doll's bottom and is used to detect when a diaper is placed in the proper location on the baby doll 100. A contact sensor SW5 is located in one of the hands and is used to detect when a toy is in the hand, or when the other hand is near so as to detect if playing patty cake or taking other action which requires the hands to be near each other.

The electronics may have a microprocessor, but preferably include a very simple processing element or controller that causes the display element 111 and other parts of the baby doll 100 to operate in the manner described herein. The processing element may be responsive to different software programs or firmware recorded on a tangible medium, such as non-volatile memory, that is executed by the baby doll to provide different functions or other aspects of operation when the power is turned on. Indeed, although not shown in FIG. 3, the tangible medium may be a removable memory, such as flash memory, that can be easily inserted or removed in the same manner as batteries. The different flash memory include respectively different software or firmware that may result in a change in the game play routine of the baby doll, the images displayed on the display, the actions to be sensed by the baby doll, or the consequences depending on whether or not the depicted action is taken in sufficient time.

The display device 110 is connected to a rear element 120 by rigid posts or other supports. Rear element 120 includes a speaker 121 as well as a battery enclosure (not shown). Preferably, the rear element 120 also includes a light sensor LS1 which detects if a blanket covers the back of the baby doll 100, or if someone is holding or burping the baby. The light sensor LS1 is preferably an inexpensive and sturdy CdS light sensor, but may be any appropriate type of light sensor that merely detects variations in light and which need not be detailed in its measurements. Although shown out of the doll in FIG. 3 for the sake of illustration, the rear element is situated entirely within the doll, but is accessible for the replacement of batteries or other elements.

The contact sensors SW3, SW4, and SW5 are preferably electrical switches operated by an applied magnetic field. For detection of an action and contact according to the invention, the other item to be detected thus must merely include a small magnet. For example, the tip of a feeding bottle may have a magnet detected by contact sensor SW3, the diaper may have a magnet detected by contact sensor SW4, and the toy may have a magnet detected by contact sensor SW5. Preferably, the other hand also has a magnet that can be detected by contact sensor SW5 when holding hands or playing patty cake. The contact sensors may be the exact same switch requiring the same magnet, or may be different switches with different sensitivities requiring different respective magnets. The electrical switches are preferably reed switches, consisting of a pair of contacts on ferrous metal reeds in a hermetically sealed package. The contacts may either be normally open, closing when a magnetic field is present, or normally closed and opening when a magnetic field is applied. The reeds are preferably in a ceramic package or any other durable package, rather than glass or similarly fragile envelope.

Of course, various embodiments of the invention may utilize a different number and type of sensors. However, the sensors are very closely correlated to the depicted actions to be taken and may vary in dependence on the action. For example, for an embodiment involving a dog, it may be required to brush the dog and an appropriate sensor would be needed to detect the presence of a hairbrush near the area of the dog to be brushed, etc. There may be magnetic sensors, sound sensors, and other kinds of sensors appropriate to the activity being detected.

FIGS. 4C-4K show examples of images and associated actions that may be utilized in the preferred embodiments involving baby doll 100. FIG. 4E shows a singing icon prompting the child to sing to the doll and FIG. 4J shows a reading icon prompting the child to read to the doll. The singing and reading actions may be detected by microphone M1. FIG. 4F shows a blanket icon prompting the child to wrap the doll in a blanket. The blanket action may be detected by a light-to-dark change (unless already light) using the light sensor LS1. FIG. 4G is a diaper icon prompting the child to put a diaper on the doll. The diaper includes a magnet detected by reed switch of contact sensor SW4. The diaper must be put on, or must already be on. FIG. 4H shows a icon prompting the child to play with the baby doll using a toy such as a rattle included in a kit with the baby doll. The toy must be in the hand and have a magnet detected by reed switch of contact sensor SW5. FIG. 4K shows an icon prompting the child to hold the baby doll. The light sensor LS1 must detect light then dark (unless already light).

Some actions can require followup. For example, FIG. 4I shows a feeding icon prompting the child to feed the baby doll. The bottle tip must be held to the mouth in order to active electrical switch of contact sensor SW3. However, even if the child performs the feeding action, the baby may randomly have hiccups after feedings, which is shown by images such as those in FIG. 4C. The hiccups may continue for a period of time, until and unless the light sensor LS1 is activated by the child burping the baby doll 100.

Some of the functions may have a timing context, consist of multiple images, and have a series of actions and interactions. For example, FIG. 4D show a sequence of images representing the playing of patty cake. To perform the action acceptably, there must be singing detected by microphone M1, and the doll's two hands must be put together so that the reed switch in contact sensor SW5 detects the magnet in the other hand. This must occur at a timing when the hands are shown put together on the screen. Furthermore, a clap sound may be played at the time(s) when the switch of contact sensor SW5 is activated. Such action as patty cake illustrated by FIG. 4D is thus not a unitary action as in some of the other actions.

Of course, the displayed images and associated actions are not limited to those shown here. There may be other images and actions prompted, such as putting the baby doll to sleep or placing the baby on her stomach or back. Of course, the baby doll may be sold with various accessories related to the displayed functions, such as a rattle or other toy, bottle, diapers, and blanket. These accessories have magnets so as to be detected by contact sensors and operate the baby doll.

Upon startup, a unique series of different images are displayed on display element 111. These images may begin with a title logo or icon, splash images, and then end with a smiley face as shown in FIGS. 4A and 5A. The title logo and splash images may scroll up to position or have some other kind of animation. There may be opening music and then, when the smiley face is displayed, perhaps a giggle sound and/or happy music. The startup routine shown in FIG. 5A begins whenever SW2 is pressed to power on the baby doll or either one of SW1 and SW2 is pressed to take the baby doll out of sleep mode 501.

After startup, the doll is controlled by the electronics so as to go through a game play routine of a sequence of prompting images and corresponding actions depicted by the images. The sequence of prompted actions may be predetermined or may be randomly selected and rotated from among the various available actions. 5B-5K shows an exemplary random game play routine. Preferably, the child can bypass any particular action they choose (if they don't want to do it or have lost an associated object necessary for performing the action) by pressing switch SW1 next to display element 111. After each action is prompted by a displayed image, the electronics detect whether the action is taken with a period of time after the image is displayed and provides a response accordingly. For example, if the child performs an action and takes care of the baby, she may be rewarded with a laughing or sleeping baby. If the baby doll is not cared for, then a crying baby image may be displayed on display element 111 (see FIG. 4B) and/or a crying sound may be played through speaker 121.

Each action may have slightly different responses. See the examples in FIGS. 5C through FI. FIGS. 5D-5G shows typical action responses. When the image is displayed (at step 4 of FIG. 5D, step 5 of FIG. 5E, step 6 of FIG. 5F, step 7 of FIG. 5G and step 9 of FIG. 5I), a fussy sound is played and repeated. If the prompted action is detected within 5 seconds, a cooing sound is played through speaker 121 and a happy image is displayed. If the prompted action is not detected within 5 seconds, then the process goes to step 12 shown in FIG. 5B. At step 12, a crying sound is played and there are alternative crying and happy screens. This is done for 5 seconds and then the doll goes back and repeats the steps shown in the respective one of FIGS. 5D-5G and FIG. 5I. This process repeats in 5 second intervals for a maximum time limit. The time limit may be, for example, 30 seconds for the reading action prompted in FIG. 5D and 20 seconds for the other actions prompted in FIGS. 5E-5G and FIG. 5I. At that point, the process continues on to step 13 in FIG. 5B.

Step 13 in FIG. 5B has a giggle sound and music playing, either simultaneously or alternating for 5 seconds, and then the routine returns to step 2 in FIG. 5B. At step 5B, there is a random wait of between 5-15 seconds, then a giggle sound plays after certain period of time. If there is any user activity, then an action is selected at random. If there is no user activity for 2 minutes, the baby doll is put into sleep mode (“standby”) if there is no input within 2 minutes.

Of course, each action in FIGS. 5D-5G and FIG. 5I is detected in different ways as shown and described previously. The process of detecting the diaper changing action (step 8 in FIG. 5H) has an additional variation in the process. Instead of merely detecting a diaper at contact sensor SW4, the process detects whether there is a change in the presence of a diaper within 10 seconds and also whether the contact sensor SW4 remains closed (meaning a diaper is on) for more than 20 seconds. This is because the child could either change the diaper on the baby doll or put a diaper on the baby doll who didn't have a diaper previously. The process either repeats at step 8 if there is no diaper change detected of proceeds to step 13 in FIG. 5B if the diaper changed is detected.

FIG. 5C shows a slightly less simple example for the feeding action associated with FIG. 4I. When the image is displayed at step 3, a fussy sound is played and repeated. If the bottle tip is detected within 5 seconds, a drinking sound is played through speaker 121 and an image is displayed. If the bottle tip is not detected within 5 seconds, then the process goes to step 12 shown in FIG. 5B. At step 12, a crying sound is played and there are alternative crying and happy screens. This is done for 5 seconds and then the doll goes back and repeats the steps shown in FIG. 5C. This process repeats in 5 second intervals for 20 seconds.

However, instead of immediately continuing to step 13 in FIG. 5B, the process continues and alternates between step 13 in FIG. 5B and step 14 in FIG. 5K. Step 13 in FIG. 5B was described above. At step 14 in FIG. 5k, a hiccup sound is played and images depicting hiccups are played. This is repeated, for example, five times. The burping action is detected, such as by sensing whether light sensor L1 detects a change in light 4 times in seconds. If burping is not detected, then the process is repeated. If burping is detected, then the routine goes to step 13 in FIG. 5B.

Finally, FIG. 5J shows the process for the patty cake action. At step 10, the fussy sound is played and repeated. The two images of two hands and clapping hands, respectively, are displayed for 2 seconds each. If the prompted action (singing at microphone M1 and hands together at contact sensor SW5) is detected within 4 seconds, a cooing sound is played through speaker 121 and a happy image is displayed. If the prompted action is not detected within 4 seconds, then the process goes to step 12 shown in FIG. 5B. At step 12, a crying sound is played and there are alternative crying and happy screens. This is done for 5 seconds and then the doll goes back to step 10 in FIG. 5J. This process repeats in 4 second intervals up to the maximum time limit of 30 seconds. At that point, the process continues on to step 13 in FIG. 5B. If the action is detected, then the whole sequence of patty cake images is displayed and repeated. A clapping sound is played each time contact sensor SW5 closes. The patty cake is repeated for up to 30 seconds or for 2 loops of the patty cake sequence, and then the process proceeds to step 13 in FIG. 5B.

Of course, all of the various parameters in the game play routine shown in FIGS. 5B-5K may be different than the values shown. For example, the time periods may be changed. The number of attempts may be change. There may be other sounds besides giggling, crying and laughing. Indeed, some of these parameters may be changed by the user. Having described at least one preferred embodiment with reference to the accompanying drawings, it is to be understood that the invention is not limited to those precise embodiments, and that various changes, modifications, and adaptations may be effected therein by one skilled in the art without departing from the scope or spirit of the invention.
