[Figure 5] FIG. 10 is a diagram showing the overall configuration of a meal simulation system according to a second embodiment. DETAILED DESCRIPTION OF THE INVENTION

[0015] First Embodiment A meal simulation system according to a first embodiment of the present invention will be described below with reference to FIGS.

[0016] (Overall configuration of the meal simulation system) FIG. 1 is a diagram showing the overall configuration of a meal simulation system according to the first embodiment. The meal simulation system 1 shown in FIG. 1 is for user A, who is unable to eat due to, for example, digestive surgery or swallowing disorder, to practice eating while taking in nutrients.

[0017] As shown in FIG. 1, the meal simulation system 1 includes a control device 10, a goggle device 11, an intraoral device (mouthpiece-type device) 12, a plate device 13, and a chopstick-type device .

[0018] The goggle device 11 is worn on the head of the user A and is capable of displaying an image of a virtual body according to the user's movements in real space (so-called AR and MR technologies are applied).

[0019] The oral device 12 is worn in the mouth of user A, and when it receives predetermined identification information from the outside (control device 10), it is capable of releasing a taste or aroma corresponding to the identification information into the user's mouth.

[0020] The plate device 13 has a receiving surface on which virtual food is superimposed and displayed by the goggle device 11. The plate device 13 has a built-in contact sensor that can detect the position on the receiving surface where an eating utensil (a chopstick-type device 14, described later) comes into contact.

[0021] The chopstick-type device 14 is modeled after the shape of real chopsticks and is held by a user. The tip of the chopstick-type device 14 is equipped with a contact-sensing member that enables the contact-sensing sensor of the plate device 13 and the contact-sensing sensor of the oral device 12 to detect contact with the chopstick-type device 14. The chopstick-type device 14 is one aspect of the eating utensils of this embodiment. Note that in other embodiments, instead of the chopstick-type device 14, a fork-type device or a spoon-type device equipped with a contact-sensing member at its tip may be used as the eating utensil.

[0022] (Control device configuration) FIG. 2 is a diagram showing the configuration of the control device according to the first embodiment. The control device 10 is a computer that controls the entire meal simulation system 1. The control device 10 may be a general computer that includes a CPU 100, a memory 101, and a communication interface 102.

[0023] The CPU 100 is a processor that performs various functions according to a program (application) prepared in advance.

[0024] The memory 101 is a storage area that stores instructions and data required for the CPU 100 to operate.

[0025] The communication interface 102 is an interface for wirelessly communicating with the various devices described above.

[0026] As shown in FIG. 2, the CPU 100 of the control device 10 functions as a display processing unit 1000, an identification information acquisition unit 1001, and a transmission unit 1002.

[0027] The display processing unit 1000 displays one or more types of virtual food (for example, a set of steak meat and side dishes in the case of a steak dish made of multiple ingredients) to the user A through the goggle device 11. The display processing unit 1000 displays the virtual food so that it is superimposed on the receiving surface of the plate device 13. This allows the user A to see the food as if it were served on a plate.

[0028] When the identification information acquisition unit 1001 detects that the tip portion (touch-sensing member) of the chopsticks-type device 14 held by user A has contacted any position on the receiving surface of the plate device 13, it acquires identification information indicating the type of virtual food corresponding to the position of contact. For example, when the tip portion of the chopsticks-type device 14 touches the position on the receiving surface of the plate device 13 where "steak meat" is displayed, the identification information acquisition unit 1001 acquires identification information corresponding to "steak meat." When the tip portion of the chopsticks-type device 14 touches the position on the receiving surface of the plate device 13 where "side dish" is displayed, the identification information acquisition unit 1001 acquires identification information corresponding to "side dish."

[0029] When the tip of the chopstick-type device 14 is brought to the mouth of user A, the transmitting unit 1002 transmits the identification information acquired by the identification information acquiring unit 1001 to the oral device 12 worn in the mouth of the user.

[0030] 1, the control device 10 according to the present embodiment is described as a computer separate from the various other devices, but other embodiments are not limited to this. That is, in other embodiments, the control device 10 may be implemented in any one of the goggle device 11, the oral device 12, the plate device 13, or the chopstick-type device 14, or the functions of the control device 10 described above may be implemented across multiple types of other devices.

[0031] (Configuration of oral device) FIG. 3 is a diagram showing the configuration of the intra-oral device according to the first embodiment. As shown in FIG. 3, the intra-oral device 12 includes a mouthpiece portion 120 and a tank portion 121.

[0032] The mouthpiece 120 is worn in a manner that it is contained in the mouth of the user A. The mouthpiece 120 is provided with a mastication sensor 120A for detecting mastication movements.

[0033] The tank section 121 has a contact sensor 121a, a plurality of tanks 121b, and an actuator 121c. The contact sensor 121a is a sensor that detects contact with the tip portion (contact sensing member) of the chopstick-type device .

[0034] Tank 121b contains a variety of sensation-forming materials, including taste-forming materials (sweeteners, sourness-forming materials, saltiness-forming materials, umami-forming materials, bitterness-forming materials, etc.), smell-forming materials (food smells), etc.

[0035] Actuator 121c is a driving member for delivering the sensation-forming material contained in each tank 121b into the mouth (mouthpiece portion 120) of user A in response to an electrical signal. For example, the sensation-forming material may be contained in tank 121b in a liquid state, and actuator 121c delivers the liquid sensation-forming material into the mouth. Alternatively, the sensation-forming material may be contained in tank 121b in a gaseous state, and actuator 121c delivers the gaseous sensation-forming material into the mouth. Furthermore, actuator 121c may process the sensation-forming material contained in a liquid state into a gas (smoke-like) and deliver it into the mouth.

[0036] (Processing flow of the meal simulation system) FIG. 4 is a diagram showing a processing flow of the meal simulation system according to the first embodiment. The processing flow shown in FIG. 4 is repeatedly executed while the meal simulation system 1 is in operation.

[0037] The display processing unit 1000 of the control device 10 displays a dish (virtual food) on the receiving surface of the plate device 13 through the goggle device 11 (step S1). Then, the user A picks up the virtual food on the plate device 13 with the chopsticks-type device 14 while watching the image displayed on the goggle device 11.

[0038] Next, the identification information acquisition unit 1001 of the control device 10 detects which food item the tip of the chopsticks-type device 14 has touched among the dishes displayed on the receiving surface of the plate device 13 (i.e., which food User A has selected), and acquires identification information indicating the type of food (Step S2). For example, if the tip of the chopsticks-type device 14 touches the position on the receiving surface of the plate device 13 where "steak meat" is displayed, the identification information acquisition unit 1001 acquires identification information corresponding to "steak meat."

[0039] The display processing unit 1000 of the control device 10 updates the image of the food displayed on the goggle device 11 to display an image of the food corresponding to the identification information acquired in step S2 being picked up with chopsticks (step S3). For example, if identification information corresponding to "steak meat" is acquired in step S2, the display processing unit 1000 causes the goggle device 11 to display an image of the "steak meat" being picked up with chopsticks. The display processing unit 1000 also updates the image of the "steak meat" superimposed on the receiving surface of the plate device 13 so that it is replaced with an image of the "steak meat" with a portion of the food being picked up with chopsticks missing. After confirming the image of the food being picked up with chopsticks, user A moves the tip of the chopstick-type device 14 closer to his or her mouth. At this time, the display processing unit 1000 may cause the goggle device 11 to sequentially update and display the image so that the image of the food being picked up with chopsticks moves in accordance with the movement of the chopstick-type device 14.

[0040] The intra-oral device 12 detects that the tip of the chopsticks-type device 14 has come into contact with the tank 121 using the contact sensor 121a (step S4). Then, the intra-oral device 12 notifies the control device 10 of the contact of the chopsticks-type device 14.

[0041] Next, when the transmitter 1002 of the control device 10 senses that the chopsticks-type device 14 has come into contact with the intra-oral device 12, the transmitter 1002 transmits the identification information acquired in step S2 to the intra-oral device 12 (step S5).

[0042] User A then brings the tip of the chopstick-type device 14 close to his mouth and begins to chew. The intraoral device 12 then detects the user's chewing action using the chewing sensor 120A of the mouthpiece 120, and dispenses a sensory-forming material corresponding to the identification information received from the control device 10 into the mouthpiece 120 (step S6). For example, if the device receives identification information corresponding to "steak meat" from the control device 10, it dispenses a sensory-forming material corresponding to "steak meat." This sensory-forming material may contain either a taste-forming material or an olfactory-forming material, or both. This allows user A to experience a realistic sensation similar to that of eating a real meal.

[0043] (Action and effect) As described above, in the meal simulation system 1 according to this embodiment, the control device 10 displays virtual food on the goggle device 11 and transmits identification information corresponding to the type of virtual food to the oral device 12, causing the taste or aroma to be released into the user's mouth.

[0044] With this configuration, meal simulation system 1 can provide user A with a realistic simulated experience of eating a real meal through sight, taste, and smell. As a result, meal simulation system 1 can give user A a sense of satisfaction as if he or she were eating, and can stimulate user A's desire to eat.

[0045] Furthermore, in the meal simulation system 1 according to this embodiment, the oral device 12 senses the chewing action of the user A and releases a sensation-forming material into the user's mouth according to the identification information.

[0046] With this configuration, meal simulation system 1 can give user A the feeling that he or she is eating real food.

[0047] Furthermore, the meal simulation system 1 according to this embodiment has a receiving surface on which an image of virtual food is superimposed by the goggle device 11, and is equipped with a plate device 13 that incorporates a sensor that can detect when the chopstick-type device 14 approaches the receiving surface.

[0048] With this configuration, the meal simulation system 1 can detect which food user A has brought the chopsticks device 14 close to (selected) from among the multiple foods included in the virtual food, and can provide user A with a sensation corresponding to the food selected by user A. Furthermore, user A can get the sensation of eating multiple foods in one meal simulation. This allows the meal simulation system 1 to further increase user A's satisfaction and motivation with regard to meals.

[0049] Furthermore, in the meal simulation system 1 according to this embodiment, when the chopstick-type device 14 is brought to the position of the virtual food, the control device 10 superimposes an image showing a part of the virtual food (for example, an image of picking up food with chopsticks) in accordance with the movement of the chopstick-type device 14.

[0050] With this configuration, meal simulation system 1 can provide user A with a realistic experience, as if he or she were eating real food with chopsticks.

[0051] In the above-described embodiment, the various processes of the control device 10 are stored in the form of a program on a computer-readable recording medium, and the computer reads and executes this program to perform the various processes. The computer-readable recording medium may include a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, etc. Alternatively, the computer program may be distributed to a computer via a communication line, and the computer that receives the program may execute the program.

[0052] The program may be for realizing some of the above-described functions. Furthermore, the program may be a so-called differential file (differential program) that can realize the above-described functions in combination with a program already stored in the computer system. Furthermore, the functions of the control device 10 may be realized using cloud computing.

[0053] As described above, several embodiments according to the present disclosure have been described, but all of these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents as defined in the claims, as well as in the scope and spirit of the invention.

[0054] <Variation 1> In the above-described embodiment, an example has been described in which the meal simulation system 1 has only one goggle device 11 worn on the head of user A, but this is not limited to this. For example, if user A is unable to eat a meal by himself, a caregiver may assist user A with eating. To be applicable to such cases, the meal simulation system 1 may have multiple goggle devices 11. In Variation 1, an example will be described in which the meal simulation system 1 has two goggle devices: a first goggle device 11 worn on the head of user A and a second goggle device 11 worn on the head of the caregiver.

[0055] In the first modification, the caregiver operates the chopsticks-type device 14 on behalf of user A to pick up the virtual food on the plate device 13 and bring it to user A's mouth. In addition, in steps S1 and S3 of FIG. 4 , the display processing unit 1000 of the control device 10 synchronizes and displays images of the virtual food on both the first goggle device 11 worn by user A and the second goggle device 11 worn by the caregiver. The images displayed on the first goggle device 11 and the second goggle device 11 are adjusted to display images of the same virtual food from different angles according to the viewpoints of the caregiver and user A, respectively. By displaying images on the first goggle device 11 and the second goggle device 11 in this way, the caregiver and user A can share information about the same virtual food (such as what food is on the plate device 13 and what food has been brought to user A's mouth). This allows user A, who needs a caregiver, to have a simulated experience of eating a real meal.

[0056] <Variation 2> In the above embodiment, the tank 121b of the oral device 12 contains a sensation-forming material corresponding to food, but the present invention is not limited to this. In Modification 2, the tank 121b of the oral device 12 may further contain a deodorizing material that eliminates the smell of food.

[0057] In the second modification, for example, the virtual food displayed through the goggle device 11 includes a palate cleanser drink or food such as "water" or "sherbet." When the user A makes a motion to eat the palate cleanser food, a deodorizing material is sent to the mouthpiece portion 120 of the intraoral device 12, thereby eliminating the smell of the virtual food that the user A has just eaten.

[0058] Here, an example will be described in which "sherbet" is prepared as a palate cleanser. In step S1 of Fig. 4, the display processing unit 1000 of the control device 10 displays an image of "sherbet" as one of the virtual foods.

[0059] In step S2 of Figure 4, the identification information acquisition unit 1001 of the control device 10 detects that the tip of the chopsticks-type device 14 (which may also be a spoon-type device) has touched the display position of "sherbet" and acquires the identification information corresponding to "sherbet."

[0060] Steps S3 to S5 in FIG. 4 are the same as those in the above-described embodiment.

[0061] 4, the intra-oral device 12 causes the deodorizing material corresponding to the identification information of “sherbet” received from the control device 10 to flow into the mouthpiece portion 120. In step S6 of FIG.

[0062] The smell of food can remind user A of the taste of the food. Therefore, meal simulation system 1 can give user A the experience of eating food by delivering an olfactory sense forming material into user A's mouth. On the other hand, meal simulation system 1 can enable user A to better enjoy the next food they will eat by delivering a deodorizing material into user A's mouth to eliminate the smell of the food they just ate. This can prevent the smells of different foods from mixing in user A's mouth, which could cause user A to lose interest in eating.

[0063] If "water" is prepared as a palate cleanser, the meal simulation system 1 may have, in addition to the chopsticks-type device 14, a cup-type device on which an image of "water" is superimposed. In this case, in step S2 of FIG. 4, when the identification information acquisition unit 1001 of the control device 10 detects the action of user A lifting the cup-type device, it acquires identification information corresponding to "water." The subsequent processing flow is the same as that in the second modification example described above.

[0064] <Second embodiment> Hereinafter, a meal simulation system according to a first embodiment of the present invention will be described with reference to FIG.

[0065] FIG. 5 is a diagram showing the overall configuration of a meal simulation system according to the second embodiment. As shown in FIG. 5, the control device 10 of the meal simulation system 1 according to the second embodiment stores a plurality of types of information in a built-in recording medium. Chewing sounds, tactile information D of chewing (hereinafter also simply referred to as "chewing sound information D"). The oral device 12 of the meal simulation system 1 according to the second embodiment further includes a bone conduction device 122.

[0066] The control device 10 is capable of communicating with the bone conduction device 122 of the intra-oral device 12. The control device 10 and the bone conduction device 122 according to the second embodiment may be connected by wire, or may transmit and receive information via wireless communication. The chewing sound information D is audio data consisting of recorded chewing sounds for various foods (steak, fried chicken, salad, etc.) This audio data is prepared in advance for each food and recorded as audio data in a recording medium built into the control device 10.

[0067] The bone conduction device 122 is one form of audio transmission means. Specifically, the control device 10 converts the chewing sound information D, which is audio data, into vibration information and transmits it to the bone conduction device 122. The bone conduction device 122 receives the vibration information and generates vibrations. User A senses the chewing sounds by sensing these vibrations through his bones. In other words, the bone conduction device 122 functions as a bone conduction speaker that transmits audio through the bones of user A (rather than through the eardrum). As a result, user A senses the chewing sounds of food directly through his bones from the vibrations of the oral device 12.

[0068] The flow of a meal simulation performed by meal simulation system 1 of the second embodiment will be described.

[0069] In the process of step S6 of FIG. 5, the control device 10 of the meal simulation system 1 according to the second embodiment further plays back chewing sound information D (audio data) via the bone conduction device 122. Here, the control device 10 uses the identification information (information indicating the type of food) obtained in step S2 to play back chewing sound information D corresponding to the identification information. For example, if user A selects "fried chicken" on the receiving surface of the plate device 13 in step S2, the control device 10 acquires the identification information indicating "fried chicken." Then, when the control device 10 senses the chewing action of user A in step S6, it plays back chewing sound information D corresponding to "fried chicken" via the bone conduction device 122.

[0070] As described above, according to the meal simulation system 1 of the second embodiment, the chewing action of user A triggers the release of the sensation-forming material and the audio playback of the chewing sounds. The audio playback of the chewing sounds is performed by bone conduction via the intraoral device 12 (bone conduction device 122). In this way, user A not only perceives the chewing sounds with his or her ears, but also senses the vibrations that are the source of the chewing sounds with his or her sense of touch (inside the mouth). This allows user A to virtually experience the sensation of actually chewing food based on both the sound information and the vibration information. Therefore, according to the meal simulation system 1 of this embodiment, user A can experience a sensation that is closer to that of actually eating a meal.

[0071] <Modification of the second embodiment> In the second embodiment described above, the mastication action of the user A is used as a trigger to execute audio playback of mastication sounds, but other embodiments are not limited to this.

[0072] For example, in a modified example of the second embodiment, the meal simulation system 1 plays video data showing a person chewing food in response to an operation (start of playback) by a caregiver on the control device 10. The video information of this video data is transmitted by the goggle device, and the audio information of the video data (chewing sounds) is transmitted via the intra-oral device 12 (bone conduction device 122).

[0073] The caregiver encourages user A to perform chewing movements in accordance with the movements of the video (video and audio of chewing food). When user A performs chewing movements in accordance with the movements of the video, meal simulation system 1 triggers the chewing movement to cause sensation-forming material to flow from intra-oral device 12.

[0074] In this way, for example, dietary training can be more effectively carried out for patients with dementia or patients with significantly reduced swallowing function (patients who have difficulty swallowing food).

[0075] The features of the meal simulation system 1 according to the second embodiment and its modifications are summarized as follows. That is, the oral device 12 in the meal simulation system 1 according to the second embodiment and its modifications further includes a means for transmitting audio and tactile information. One aspect of the means for transmitting audio and tactile information is a bone conduction device 122. The control device 10 in the meal simulation system 1 according to the second embodiment and its modifications transmits the sound of chewing food and sensory information about the chewing of the food as vibration information via the audio transmission means (bone conduction device 122).
