[1-2. processing]
[1-2-1. Data transmission processing]
Next, a data transmission process executed by the control unit 28 of the eating utensil 2 will be described with reference to the flowchart of FIG. The data transmission process is periodically executed while the power of the eating utensil 2 is on.

  First, in S101, the control unit 28 acquires sensor information from the acceleration sensor 23 and the touch sensor 24. The sensor information referred to here is information including the measurement results of the sensors 23 and 24 and the measurement time.

  Subsequently, in S102, the control unit 28 transmits the sensor information acquired in S101 to the information device 3 via the communication unit 25. The sensor information transmitted from the eating utensil 2 and received by the information device 3 is stored in the storage unit 34 of the information device 3. After executing S102, the control unit 28 ends the data transmission process of FIG.

[1-2-2. Content output processing]
Next, content output processing executed by the control unit 37 of the information device 3 will be described with reference to the flowchart of FIG. The content output process is periodically executed while the eating determination application is running. During the execution of the content output process, the information device 3 is on the side of the user who is eating with the meal utensil 2 (at least the content such as sound or image output from the information device 3 reaches the user or It is assumed that it exists within the range that can be confirmed.

  First, in S201, the control unit 37 acquires from the storage unit 34 the sensor information received and stored from the eating utensil 2. Here, the control unit 37 acquires the sensor information over the past fixed time from the storage unit 34. The certain time period in the past is set based on the time from when the user holds the food using the eating utensil 2 until the user puts the food in the mouth.

  Subsequently, in S202, the control unit 37 determines whether or not the user has eaten using the eating utensil 2 based on the sensor information acquired in S201. Here, based on the acquired sensor information, the control unit 37 changes the state of the eating utensil 2 from a state in which acceleration acts downward in the vertical direction (that is, the direction of gravity) (hereinafter, a downward state). The tip of the eating utensil 2 is switched by the touch sensor 24 within a predetermined time after switching to a state in which acceleration is acting above (hereinafter, ascending state) and detecting switching from the descending state to the ascending state. When the contact with the user 22 is detected, it is determined that the user has eaten using the eating utensil 2.

  The reason why the criterion is set in this way is as follows. When the user eats, first, the user brings the food utensil 2 close to the food from above in order to hold the food with the food utensil 2 (that is, the vertical acceleration is applied to the food utensil 2). When the user holds the food with the food utensil 2, the user carries the food to the user's mouth (that is, the food utensil 2 rises, and the vertical acceleration is applied to the food utensil 2). That is, when this action is performed, the state of the eating utensil 2 switches from the descending state to the ascending state. When the user includes food in his / her mouth, contact with the tip 22 of the eating utensil 2 is detected. For this reason, in the present embodiment, the above-described determination criterion is set as a criterion for determining whether or not the user ate with the meal utensil 2.

  When the distal end portion 22 of the eating utensil 2 is included in the user's mouth, liquid (saliva) in the mouth adheres to the touch sensor 24, and the capacitance detected by the touch sensor 24 changes. The touch sensor 24 detects contact with the tip 22 by detecting the change in the capacitance.

  The predetermined amount of change in the capacitance, which is the threshold value when the touch sensor 24 determines that there is a contact, depends on the moisture attached to the touch sensor 24 when the tip portion 22 comes into contact with food such as vegetables. The capacitance is set to be larger than the standard change amount. Further, the predetermined amount of change is set to be smaller than a standard amount of change in capacitance due to moisture adhering to the touch sensor 24 when the tip 22 is included in the mouth of the user. This means that when the tip portion 22 is brought into contact with food such as vegetables, it is determined by the touch sensor 24 that there is a contact, and at that point, it is erroneously determined that there was eating (the act of the user including food in the mouth). This is for suppressing.

When it is determined that the user has eaten in S202 (S202: YES), the control unit 37 shifts to S203 and outputs the content via the speaker 33.
Specifically, in the present embodiment, when the user's eating is detected, a sound selected in advance is reproduced in accordance with the user's eating behavior. The sounds reproduced here include, for example, sounds related to foods and ingredients eaten by the user, sound effects that do not make the user tired, and the like. Such sounds include, for example, sounds of onomatopoeia of food or food ingredients (for example, “garlic” if food is carrot), and rhythmical sounds of quizzes on food or food ingredients. (For example, "What color are you eating? Green? Orange?"). Further, for example, onomatopoeia (for example, a sound such as "Pakupaku") related to eating behavior, and other interesting sound effects may be mentioned.

  The type of sound to be reproduced can be selected with the eating judgment application. For example, when playing a sound in which the name of an ingredient is converted to onomatopoeia, the parent of the user selects the ingredient in advance in the eating determination application, and the selected sound is output when the eating of the user is detected.

  Specifically, in this embodiment, when the eating determination application is activated and a predetermined software button displayed on the display unit 31 is selected, a food list is displayed on the display unit 31. Then, when the parent of the user selects one or a plurality of ingredients that the user eats, a sound corresponding to the selected ingredients is output. When a plurality of ingredients are selected, sounds corresponding to the selected ingredients are output at random. In the present embodiment, a plurality of patterns of sounds having different timbres and / or voice qualities can be selected, and the parent of the user selects a sound to be reproduced from the plurality of patterns of sounds.

  Subsequently, in S204, the control unit 37 increases the number of times of eating stored in the storage unit 34 by one. Here, the storage unit 34 stores the number of eating times since the user's meal started, and the control unit 37 increases the number of eating times by one. It should be noted that various determination methods are conceivable for determining whether or not the user's meal has started. For example, it may be simply determined that the user's meal is started when the eating determination application is activated.

After executing S204, the control unit 37 proceeds to S205 described later.
On the other hand, when it is determined in S202 that the user is not eating with the eating utensil 2 (S202: NO), the control unit 37 skips S203 and S204 and proceeds to S205.

In S205, the control unit 37 acquires the number of times of eating since the start of the meal from the storage unit 34.
Subsequently, in S206, the control unit 37 outputs the content based on the number of times of eating acquired in S205 via the display unit 31. Specifically, the control unit 37 changes the content displayed on the display unit 31 in real time according to the number of times of eating by the user. For example, as shown in FIG. 8, the control unit 37 causes the display unit 31 to display the number of times of eating, and changes the number of times of eating in real time according to the user's eating. Further, for example, the control unit 37 causes the display unit 31 to output contents such that plants such as grass increase in accordance with the number of times of eating by the user, and animals such as panda eat in accordance with the change in the number of times of eating.

Subsequently, in S207, the control unit 37 determines whether or not the number of times of eating acquired in S205 is a certain number or more.
When the control unit 37 determines in S207 that the number of times of eating is equal to or more than the predetermined number (S207: YES), the process proceeds to S208, and causes the content to be output via the display unit 31 and the speaker 33. For example, the control unit 37 outputs content that motivates the user. Such content includes, for example, sound or image output such as “I ate five times, amazing!”. After executing S208, the control unit 37 proceeds to S209 described below.

  On the other hand, if it is determined in S207 that the number of times of eating is not equal to or more than the certain number of times (that is, less than the certain number of times) (S207: NO), the control unit 37 skips S208 described above and proceeds to S209.

In S209, the control unit 37 determines how to eat by the user based on the sensor information acquired in S201.
Specifically, in S209, the control unit 37 determines whether or not the user is eating food or food using the eating tool 2 correctly. When performing this determination, the control unit 37 performs the following two determinations (determination A and determination B).
(Determination A) Based on the measurement result of the acceleration sensor 23, the control unit 37 determines whether the eating utensil 2 is kept horizontal between the time when the user holds the food using the eating utensil 2 and brings the food to the mouth. Determine whether or not. Specifically, the control unit 37 determines the vertical direction (based on the measurement result of the acceleration sensor 23 from when the state of the eating utensil 2 is switched from the down state to the up state until the contact is detected by the touch sensor 24). That is, the inclination angle of the eating utensil 2 with respect to the direction of gravity is determined. Then, the control unit 37 determines whether or not the eating utensil 2 is kept horizontal based on the determined inclination angle.
(Determination B) The controller 37 determines whether the user is swinging or throwing the eating utensil 2 based on the measurement result of the acceleration sensor 23. For example, when the controller 37 detects an irregular acceleration vertically upward or vertically downward (for example, the descending state and the ascending state are switched a plurality of times in a short period of time) or a sudden horizontal acceleration is detected. Then, it is determined that the user is throwing or swinging the eating utensil 2. On the other hand, when such irregular acceleration or the like is not detected, the control unit 37 determines that the user has not thrown or swung the eating utensil 2.

  The control unit 37 determines that the eating utensil 2 is kept horizontal between the time when the user holds the food using the eating utensil 2 and carries it to the mouth in the determination A (determination A: YES), and If it is determined in determination B that the user is not swinging or throwing the eating utensil 2 (determination B: NO), it is determined that the user is properly using the eating utensil 2 and eating food. On the other hand, when the control unit 37 determines that the eating utensil 2 is not kept horizontal between the time when the user holds the food with the eating utensil 2 and brings it to the mouth in the determination A (determination A: NO), Alternatively, when it is determined that the user is swinging or throwing the eating utensil 2 (determination B: YES), it is determined that the user does not use the eating utensil 2 correctly and eats food.

  Subsequently, in S210, the control unit 37 outputs the content via the speaker 33 based on the determination result in S209. Specifically, if the control unit 37 determines in S209 that the user is eating food with the correct use of the eating utensil 2, the control unit 37 uses the speaker 33 to give a compliment (“I was able to eat good food. Etc.). On the other hand, if it is determined in step S209 that the user does not eat the food by using the meal utensil 2 correctly, the control unit 37 uses the speaker 33 to provide feedback according to the user's eating style ("No, let's handle it properly"). Etc.) is output.

  Subsequently, in S211, the control unit 37 determines the eating speed of the user based on the sensor information acquired in S201. More specifically, the control unit 37 controls the touch sensor 24 from when the user holds the food using the eating utensil 2 until the user includes the food in the mouth (after the state of the eating utensil 2 switches from the down state to the ascending state). If the time (until contact is detected) is less than the predetermined time, it is determined that the user's eating speed is fast. On the other hand, the control unit 37 determines that the eating speed of the user is not fast when the time from when the user holds the food using the meal utensil 2 to when the user includes the food in the mouth is a predetermined time or more.

  Subsequently, in S212, the control unit 37 outputs the content based on the determination result in S211 via the speaker 33. Specifically, when it is determined in S211 that the user's eating speed is fast, the control unit 37 outputs a sound (such as a sound “slowly”) prompting the user to eat slowly through the speaker 33. Output.

  Subsequently, in S213, the control unit 37 determines whether or not the user has stopped eating. Here, the control unit 37 determines that the user's eating has stopped if the user's eating is not detected for a predetermined time or more after the determination in S202 that the user has eaten most recently.

  When it is determined in S213 that the user has stopped eating (S213: YES), the control unit 37 proceeds to S214 and determines whether or not the user is still eating. In the present embodiment, it is determined that the user is still eating when the number of eating times of the user since the start of the meal is less than the predetermined number. On the other hand, when the number of eating times of the user since the start of the meal is equal to or more than the predetermined number, the control unit 37 determines that the user is not eating (that is, the meal is finished).

  When it is determined in S214 that the user is still eating (S214: YES), the control unit 37 shifts to S215 and outputs a content prompting eating via the speaker 33. For example, the control unit 37 outputs a sound such as "I'm almost eating out" as content that encourages eating. After executing S215, the control unit 37 proceeds to S217 described later.

  On the other hand, when it is determined in S214 that the user is not eating (that is, the meal is finished) (S214: NO), the control unit 37 shifts to S216, and the content after eating is completed via the speaker 33. Is output. Specifically, the control unit 37 feeds back the content of the meal and outputs a content praising the eating (such as a voice saying “I ate a lot of vegetables! Amazing!”). After executing S216, the control unit 37 proceeds to S217.

  In S217, the control unit 37 transmits to the server 4 the various types of determination data in S202, S207, S209, S211, S213, and S214, eating data including the eating time, food information, and the like, and the user information, as shown in FIG. Ends the content output process.

[1-3. effect]
According to the first embodiment described in detail above, the following effects can be obtained.
(1) In the present embodiment, the control unit 37 of the information device 3 determines whether or not the user has eaten using the eating utensil 2 based on the sensor information transmitted from the eating utensil 2. Therefore, the eating of the user such as a child can be detected by a novel method.

  Further, according to the present embodiment, it is possible to suppress occurrence of erroneous detection of the user's eating as compared with the eating utensils described in Patent Document 1 described above. That is, in the eating utensil described in Patent Literature 1, when the user holds the eating utensil in his hand and includes the tip of the eating utensil in his mouth, the switch conducts through the user's body, and a sound is emitted from the speaker. In other words, in this configuration, the eating judgment is performed by focusing on only a part of the action of holding the food using the eating utensils, carrying the food to the mouth, and including the food in the mouth in a series of eating actions of including the food. Do. Therefore, for example, it is erroneously detected that the user ate even if the user includes the tip of the eating tool in his / her mouth in a state where the eating tool does not hold food. On the other hand, according to the present embodiment, the user's eating is determined by detecting the entire series of eating operations described above. Therefore, it is possible to suppress occurrence of erroneous detection of the user's eating as compared with a configuration in which the eating judgment described in Patent Document 1 focuses on only a part of the series of eating operations and performs the eating determination. I can do it.

  In addition, according to the present embodiment, by detecting the series of eating operations, the user's meal form including the user's eating style is detected, and the content is output based on the result, thereby promoting dietary education. be able to.

  (2) In the present embodiment, when the control unit 37 determines that the user has eaten, the control unit 37 outputs the content to the display unit 31 that can output the image as the content and the speaker 33 that can output the sound as the content. . Therefore, when it is determined that the user has eaten, the content is output, and as a result, children can enjoy eating. As a result, it is possible to spontaneously encourage children to eat even foods and ingredients that they are not good at.

  (3) In the present embodiment, when it is determined that the user has eaten, the content is output from the display unit 31 and the speaker 33 of the information device 3. That is, the content is output via the display unit 31 and the speaker 33 which are usually mounted on the information device 3. Therefore, the content can be output to the user without providing the dining utensil 2 with a speaker or the like capable of outputting the content. Therefore, the manufacturing cost of the meal utensil 2 can be reduced as compared with a configuration in which a speaker or the like is provided on the meal utensil 2 and content is output from the speaker or the like.

(4) In the present embodiment, the control unit 37 counts the number of eating times of the user, and causes the display unit 31 and the speaker 33 to output the content based on the counted number of eating times.
Specifically, the control unit 37 changes the content (image) displayed on the display unit 31 in real time according to the number of times of eating by the user. It is conceivable that the child eats while watching the display unit 31 when eating. The image displayed on the display unit 31 changes in real time in accordance with the number of times of eating, so that the child can enjoy eating. As a result, eating of the child can be promoted. In addition, when the control unit 37 determines that the number of times of eating by the user is equal to or more than the certain number, the control unit 37 outputs the content via the speaker 33. Therefore, it is possible to improve a child's motivation to eat.

  (5) In the present embodiment, when it is determined that the user has stopped eating, the control unit 37 causes the speaker 33 to output the content. Specifically, when it is determined that the user has stopped eating and the user determines that the user is still eating, the control unit 37 outputs a content that prompts the user to eat. Therefore, the user can eat food to the end and reduce the amount of leftover. In addition, when it is determined that the meal has been finished when it is determined that the user has stopped eating, the control unit 37 outputs a content complimenting that the user has finished eating. Therefore, the user's motivation for a complete meal can be improved.

  (6) In the present embodiment, the control unit 37 determines the user's eating speed, and causes the speaker 33 to output the content based on the determined eating speed. Therefore, for example, by outputting a content that prompts the user to eat slowly when the eating speed is high, it is possible to teach the user an appropriate eating speed.

  (7) In the present embodiment, the control unit 37 determines the user's eating style using the meal utensil 2 and causes the speaker 33 to output the content based on the determined user's eating style. Therefore, for example, by outputting content that feeds back the correct way to eat when the user is not eating correctly, it is possible to teach the user how to eat correctly.

  In the present embodiment, the communication unit 25 corresponds to a meal communication unit, the display unit 31 and the speaker 33 correspond to a content output unit, and the communication unit 36 corresponds to a device communication unit. In addition, S102 corresponds to processing as a measurement transmission processing unit, S201 corresponds to processing as a measurement acquisition processing unit, S202 corresponds to processing as a eating determination unit, and S203, S206, S208, S210, S212, S215 and S216 correspond to the processing as the output processing unit.
