Description

  The present invention relates to a nutrition management support system for supporting nutrition management of a person who receives meal guidance. In particular, the present invention relates to a nutrition management support system using a communication line (for example, the Internet, LAN, etc.). The present invention also provides a nutrition management ability training system that trains the nutrition management ability and nutrition guidance ability of a nutritional instructor (for example, a dietitian, a doctor, etc.) or a person who aims to be a nutritional instructor (for example, a student at a dietitian vocational school). About.

  Japanese Patent Laid-Open No. 2002-149828 discloses a nutrition management support system in which a nutritional instructor (for example, a dietitian, a doctor, etc.) provides nutritional guidance for a patient (for example, a diabetic patient) by using a communication line. In this nutrition management support system, a terminal device (personal computer, mobile phone, PDA, etc.) operated by a patient is connected to a nutrition consultation center via a communication line. The client photographs the contents of his / her meal with a digital camera or the like and sends it to the nutrition consultation center. When receiving the meal image from the client, the nutrition consultation center transmits the meal image to the nutritional instructor. When the nutritional instructor receives a meal image from the nutrition consultation center, the nutritional instructor calculates a nutrition amount (total calories, protein, etc.) for the meal image, and also creates a comment. The calculated nutrition amount (total calories, protein, etc.) is transmitted to the client's terminal device via the nutrition consultation center together with the comments of the nutritional advisor. The client receives the calculated nutrient amount and the comment transmitted from the nutrition consultation center with his / her terminal device. Therefore, according to this nutritional management support system, the patient can receive nutritional guidance from the nutritional instructor even if the patient and the nutritional instructor do not meet directly.

By the way, the ability of a nutritional instructor (such as a dietitian) to calculate the amount of nutrition varies greatly depending on the years of experience and the content of the work involved. For example, a nutritional instructor who mainly performs menu preparation work is not familiar with nutrition calculation work, and there is a person who is not good at nutrition calculation work. On the other hand, a nutritional instructor who routinely performs nutrition calculation work can calculate nutrition with high accuracy. For this reason, even if a plurality of nutritional leaders calculate the nutritional amount for the same meal content, the nutritional value calculated by each nutritional advisor varies greatly (see FIGS. 28 and 29). In addition, the size of the variation that occurs depends on the nutrient that is calculated. As shown in FIGS. 28 and 29, the calorie amount can be calculated with relatively high accuracy, but the protein amount varies greatly. In addition, when calculating nutrients from meals taken with a digital camera, the calculation accuracy varies depending on the type of menu (especially the difference in cooking method) and the container in which the meal is served. It has been reported that there can be a big difference between nutritional amount (Hatsue Naito: Research on the effectiveness of nutritional surveys using a simple method "Nutritional surveys using digital cameras", Shizuoka Prefectural University Junior College Department of Research Bulletin 15-W (2001) -2).
Therefore, the nutritional amount calculated by the nutritional instructor may be incorrect, and even if dietary improvement or nutritional guidance is performed based on the incorrect nutritional amount, it is not possible to have a nutritionally appropriate dietary life. Can not. The above prior art does not evaluate whether or not the nutritional amount calculated by the dietitian is correct, and nutritional guidance and advice are given based on the incorrect nutritional amount. It can happen that improvements are made.

In addition, you may make it image | photograph the meal of step S10 not only before a meal but after a meal. By performing post-meal photography, the nutritional instructor can grasp how much food has been left, and can more accurately calculate the amount of nutrition (total calories, protein) consumed by the client.

  Next, the requester connects the requester terminal 10 to the nutrition management support homepage, and proceeds from the nutrient calculation requester site to the transmission site (S12). If it progresses to a transmission site, the image data of the meal image | photographed by step S10 will be transmitted to the management server 30 (S14). As a result, the request for calculation of nutrients by the client ends.

(2) Receiving a meal image by the management server 30 When receiving a meal image from the client terminal 10, the management server 30 stores the meal image in the meal image file 32a. At that time, an identification number (image number) is given to the meal image, and the ID of the sender (requester) is associated and stored so that the sender can be specified.
In addition, the management server 30 memorize | stores the meal image received in the reception period as one group in the meal image file 32a for every predetermined reception period (for example, 1 day). The meal image group belonging to the same group stored in the meal image file 32a is not transmitted to the nutritional instructor terminal 20 in the period in which the meal image is received, and is transmitted to the nutritional instructor terminal 20 in the next reception period. The nutritional amount is calculated by the nutritional instructor. The meal image for which the nutrient amount has been calculated is deleted from the meal image file 32a when the next reception period starts.

(3) Transmission of meal image to nutritional instructor by management server 30 and return of calculated nutritional amount to requester Transmission of meal image from management server 30 to nutritional instructor terminal 20 and calculation by nutritional instructor Processing for transmitting the nutrient amount from the management server 30 to the client terminal 10 will be described.
As shown in FIG. 12, first, the management server 30 determines whether or not there is an access from the nutrition leader terminal 20 (S20). That is, in this embodiment, when the nutritional instructor operates the nutritional guidance terminal 20 to connect to the nutritional amount calculation site on the nutritional management support homepage, the management server 30 transmits a meal image to the nutritional guidance terminal 20. It has become. Therefore, the management server 30 first determines whether or not there is an access to the nutrition calculation site from the nutrition leader terminal 20.
If there is no access from the nutritional advisor terminal 20 (NO in step S20), the process waits until there is access, and if there is an access from the nutritional advisor terminal 20 (YES in step S20), the process proceeds to step S22. In the above-described embodiment, the process waits until there is an access from the nutrition instructor terminal 20 in the case of NO in step S20. However, the present invention is not limited to such a form. It may be programmed to start an interrupt process when there is an access from the instructor terminal 20 and proceed to the next process by this interrupt process.

  In step S22, the management server 30 first selects image data to be transmitted to the nutritional advisor terminal 20 (S22). In the present embodiment, a predetermined number of images (for example, seven images) randomly selected from the group of meal images received in the immediately preceding reception period stored in the meal image file 32a and the test image file 36 are stored. A predetermined number of images (for example, three images) randomly selected from the stored test meal image group are mixed and a meal image group to be transmitted to the nutritional instructor terminal 20 is created.

The meal image group created in step S22 is transmitted to the nutritional advisor terminal 20 (S24). FIG. 13 shows an example of an image displayed on the display device 24 of the nutritional advisor terminal 20. As shown in FIG. Ten meal images from 1 to 10 are displayed. As is clear from the figure, the meal image requested by the client and the test meal image are randomly mixed, so the nutritional instructor does not know which meal image is the test meal image. It has become.
When each meal image in the image shown in FIG. 13 is clicked, the clicked meal image is enlarged and displayed as shown in FIG. As a result, the nutritional instructor can easily estimate the size of the food in the meal image, and the calculation accuracy of the nutritional amount can be increased.
Each meal image displays a column in which the nutrition amount (total calories, protein) of the meal image can be input. When the nutritional instructor calculates the nutritional amount (total calories / protein) for the meal image, the nutritional instructor inputs them into each column of the meal image. The processing in the nutrition instructor terminal 20 will be described in detail later.

  When the meal image is transmitted to the nutritional advisor terminal 20, the management server 30 next determines whether or not the calculated nutritional amount is returned from the nutritional advisor terminal 20 (S26). If there is no reply from the nutritional instructor terminal 20 (NO in step S26), the process waits until there is a reply, and if there is a reply from the nutritional instructor terminal 20 (YES in step S26), the process proceeds to step S28. In the above-described embodiment, the system waits until there is a reply from the nutritional instructor terminal 20, but the present invention is not limited to such a form, and access from the requester terminal 10 and the nutritional instructor terminal 20 is performed. It may be programmed to start an interrupt process when there is an error and proceed to the next process by this interrupt process.

In step S28, the nutritional amount calculation accuracy of the nutritional instructor who has returned the calculated nutritional amount is calculated (S28). That is, the meal image group transmitted to the nutritional instructor includes a plurality of test meal images. Accordingly, the nutrition amount returned from the nutrition instructor terminal 20 includes the nutrition amount calculated for the test meal image. Therefore, the calculation accuracy of the nutritional instructor is calculated based on the nutrient amount calculated for the test meal image and the nutrient amount measured in advance for the test meal image.
Specifically, for each test meal image transmitted to the nutrition instructor, the nutrition number of the test meal image stored in the nutrient file 35 is searched using the image number of the test meal image as a key. To do. Then, the calculation accuracy is calculated from the following formula using the searched nutrient amount and the nutrient amount calculated by the nutritional instructor.
Calculation accuracy = (1- | (calculated nutrient amount-searched nutrient amount) | / searched nutrient amount) × 100%
The calculation accuracy described above is calculated for total calories and also for proteins. In addition, the calculation accuracy is calculated for each test meal image. Therefore, if the number of test meal images transmitted to the nutritional instructor is n, the number of calculation accuracy calculated in step S28 is 2 × n.
Various formulas can be used as formulas for calculating the calculation accuracy. For example, calculation error accuracy = | calculated nutrient amount−searched nutrient amount | / searched nutrient amount × 100%, deviation value, etc. can be used.

  Next, the management server 30 updates the calculation accuracy of the nutritional leader stored in the nutritional advisor file 38 using the calculation accuracy calculated in step S28 (S30). That is, a new calculation accuracy (average value) of the nutritional leader is calculated using the calculation accuracy of the nutritional leader stored in the nutritional advisor file 38 and the calculation accuracy calculated in step S28. For example, if the calculation accuracy of the nutritional instructor stored in the nutritional instructor file 38 has been calculated for m test images, first, the currently stored calculation accuracy is multiplied by m. Next, all the calculation accuracy (for example, 2 × n calculation accuracy) calculated in step S28 is added to the multiplied value, and the added value is divided by the calculated number of test meal images (2n + m). A new calculation accuracy is calculated by such a method. Moreover, based on new calculation accuracy, it classify | categorizes into any of A, B, and C ranks as the nutritional amount calculation ability of the said nutrition leader. In the calculation example described above, one calculation accuracy is used for each test meal image performed in the past, and two calculations of total calorie and protein are used for each test meal image calculated this time. A new calculation accuracy (average value) is calculated using the accuracy. By weighting the current calculation accuracy with respect to the past calculation accuracy in this way, it is possible to more accurately reflect the current nutrition amount calculation ability of the nutritional leader. Various methods can be used for weighting. For example, a simple interior dividing point may be used.

When the nutrition leader file 38 is updated, the nutrient amount (nutrient amount calculated for the meal image other than the test meal image) transmitted from the nutrition leader terminal 20 is stored (S32). At this time, the nutrition amount is stored in association with the image number assigned to each meal image so that it can be specified for which meal image the calculated nutrition amount is calculated.
Next, the management server 30 transmits a ranking table created based on the calculation accuracy of the nutritional advisor and the calculation accuracy of the nutritional advisor to the nutritional advisor terminal 20 (S34). That is, the management server 30 ranks the nutritional leaders in descending order of calculation accuracy, and transmits a ranking table obtained by the ranking to the nutritional leader terminal 20. Note that the information returned to the nutrition instructor terminal 20 is not limited to the above-described example, and can take various forms. For example, the ranking based on the calculation accuracy newly calculated in step S30, the calculation accuracy calculated in step S28 (average of two calculation accuracy of total calorie and protein), calculation accuracy ± error, and the like may be returned.

When the calculation accuracy / ranking table is transmitted to the nutrition leader terminal 20, the management server 30 determines whether or not the current acceptance period has ended (S36). If the current acceptance period has not ended (NO in step S36), there is still a possibility that the meal image for which the nutritional amount has been calculated is transmitted to other nutritional instructors. The processing from S20 is repeated.
If the current acceptance period has ended (NO in step S36), the requester is provided with the nutrition (total calories, protein) calculated for the meal image for each meal image transmitted from the requester terminal 10. It transmits to the terminal 10 (S40). When a plurality of nutritional leaders have calculated the nutritional amount for the same meal image, the nutritional amount calculated by the nutritional advisor with the highest calculation accuracy is transmitted to the client. At that time, the nutritional calculation ability (any of A, B, and C ranks) of the nutritional leader is transmitted, and the comment created by the nutritional advisor is transmitted. Such information can be transmitted by e-mail.
In addition, when a plurality of nutritional leaders having a reliable nutritional amount calculation ability (A rank) are calculating the same meal image, the average value of the nutritional amounts calculated by the plurality of nutritional advisors is transmitted. It may be. At this time, the nutritional amount can be calculated by weighting according to the calculation accuracy of each nutritional instructor.

(4) Calculation of nutritional amount of nutritional leader Next, the nutrition image when the meal image is transmitted from the management server 30 to the nutritional guidance terminal 20 and the calculated nutritional value is returned from the nutritional guidance terminal 20 to the management server 30 Processing in the leader terminal 20 will be described.
As shown in FIG. 15, the nutritional instructor first operates the nutritional instructor terminal 20 to connect to the nutritional amount calculation site on the nutritional management support homepage (S44). When the nutrition leader terminal 20 is connected to the nutrition calculation site, the management server 30 sends a meal image group (a mixture of meal images from the requester and test meal images) to the nutrition leader terminal 20. The meal image group is received by the nutrition instructor terminal 20 (S46). As a result, the image shown in FIG. 13 is displayed on the display device 24 of the nutrition instructor terminal 20. Therefore, the nutritional instructor calculates a nutrition amount (total calories, protein) for each meal image displayed on the display device 24. At that time, when the meal image in the screen is clicked, the clicked meal image is enlarged as shown in FIG. 14, and the size of the food in the image is easily grasped. The calculated nutrient amount (total calories, protein) is input to the column in the screen. Note that the nutrient amount (total calories, protein) may be input by voice.

  When the calculated nutrition amount (total calories, protein) is input, the nutrition leader terminal 20 transmits the nutrition amount (total calories, protein) to the management server 30 (S48). Next, the nutrition instructor terminal 20 receives the calculation accuracy and ranking (ranking table) transmitted from the management server 30, and displays the received calculation accuracy and ranking on the display device 24 (S50). As a result, the nutritional instructor can know his / her calculation accuracy and the rank among the registered nutritional instructors.

(5) Others In the nutrition management support system according to the present embodiment, in addition to the management server 30 notifying the client of the calculated nutrition amount by e-mail, the client himself operates the client terminal 10 to operate the nutrition management support homepage. The calculated nutrition can be received directly.
In that case, as shown in FIG. 11, the requester operates the requester terminal 10 to connect to the nutrient calculation requester site (reception site) in the nutrition management support homepage (S16). When connected to the receiving site, the self ID and password are input, and the input ID and password are transmitted to the management server 30. The management server 30 collates the ID transmitted from the client terminal 10 and the password, and if it is correct, transmits the calculated nutrition amount and dietary guidance (comment) of the corresponding client, and the client terminal 10 receives this. (S18). As a result, even when the requester cannot receive e-mail, the client can know the calculated nutrient amount by operating another information terminal.

In this nutrition management support system, a person who wishes to register as a nutritional instructor can apply for registration as a nutritional instructor by operating his / her terminal.
As shown in FIG. 16, the registration applicant first operates his / her terminal to connect to a nutritionist registration site on the nutrition management support homepage (S52). When connecting to the registration site, a predetermined registration form is displayed on the terminal, so that the applicant for registration inputs necessary information (e-mail address, etc.) (S54).
When necessary information is input, the applicant for registration transmits the input information to the management server 30 (S56). Upon receiving these pieces of information, the management server 30 assigns an ID and a password to the person who wants to register, and registers the person who wants to register in the nutritional instructor file 38 as a nutritional instructor. Then, the management server 30 returns the ID and password to the registration applicant, and the registration applicant receives the ID and password (S58). Thereafter, the applicant for registration can input the ID and password to connect to the nutrition calculation site of the nutrition management support homepage, and can calculate the nutrition as a nutritional instructor.

As described above, according to the nutrition management support system of this embodiment, the nutritional ability of the nutritional instructor is evaluated, and the client is notified of the nutritional quantity calculated by the person with the most nutritional ability. . Therefore, it is possible to prevent erroneous nutritional guidance and advice from being given to the client. In addition, when notifying the requester of the nutrition amount, the nutritional ability calculation ability (A, B, C rank) of the nutritional instructor who calculated the nutrition amount is also notified. For this reason, the client can decide by himself whether or not to follow the nutritional guidance of the nutritional advisor.
Further, since the nutritional instructor's ability to calculate the nutritional amount is determined every time the nutritional amount of the meal image is calculated, the nutritional instructor's ability to calculate the nutritional amount is evaluated in real time. Therefore, it is possible to increase the possibility that a correct nutrition amount and nutrition guidance are given to the client.
In addition, nutritional leaders can objectively grasp their own nutritional calculation ability by comparing them with other nutritional advisors, so that they have an incentive to improve their nutritional capacity calculation ability. Can be given.
Furthermore, the nutrition management support system of this embodiment can connect the person who wants to calculate the dietary nutrition and the person who undertakes the nutritional calculation through the Internet, and can provide the dietary nutrition of an unspecified number of people at low cost. Can support efficiently.

  In the above-described embodiment, the nutrition calculation accuracy is calculated by the management server 30. However, the nutrition calculation accuracy may be calculated by the nutrition instructor terminal 20. For example, when the management server 30 transmits the test meal image to the nutrition instructor terminal 20, the management server 30 also transmits the nutrition amount of the test meal image. When the nutrition amount is input for the test meal image, the nutrition leader terminal 20 calculates the calculation accuracy from the input nutrient amount, and transmits the calculated calculation accuracy to the management server 30. Even with such a configuration, it is possible to obtain the same effects as the above-described embodiment.

Specific examples of the present invention have been described in detail above, but these are merely examples and do not limit the scope of the claims. The technology described in the claims includes various modifications and changes of the specific examples illustrated above.
(1) When registering a person who wishes to register as a nutritional instructor, the person who wants to register may be tested for nutritional capacity calculation ability and registered according to the test result. For example, when there is an access from a registration applicant to the management server, first, the management server transmits a plurality of test meal images to the terminal of the registration applicant. The registration applicant calculates the nutrient amount (total calories, protein) for the plurality of transmitted meal images, and transmits them to the management server. The management server calculates the nutritional amount calculation accuracy of the registration applicant from the transmitted nutritional amount and the like, and determines the nutritional amount calculation ability of the registration applicant based on the generated calculation accuracy. And the management server can register only those who have a certain nutrition amount calculation capability as nutritional leaders. Thereby, the calculation accuracy of the nutrient amount notified to the client can be ensured.
In addition, when employ | adopting such a structure, it is good also as a structure which deletes the registration as a nutritional instructor, when the nutrition amount calculation ability of a nutritional instructor becomes below a fixed level. As a result, even after registering as a nutritional instructor, the nutritional instructor is required to maintain a high ability to calculate his / her nutrition, and to ensure the accuracy of the nutrition notified to the client. Can do.

(2) In the above-described embodiment, the nutritional instructor's ability to calculate the nutritional amount is determined every time the nutritional amount is calculated with respect to the meal image from the client, but the present invention is limited to such a form. I can't. For example, a plurality of test meal images may be periodically transmitted to the nutritional instructor to evaluate the nutritional capacity calculation ability of the nutritional instructor. As a result, the nutritional instructor's ability to calculate nutrition can be secured.

(3) Nutrition guidance by a nutrition instructor can be performed in various ways. For example, only a comment may be notified as in the above-described embodiment, or an appropriate meal amount may be written (designated) on the received meal image, and the requester may be notified of the meal image. Good. By providing nutrition guidance in such a manner, nutrition guidance to the client becomes more specific, and appropriate nutrition guidance is given.
In this case, the requester may transmit a meal image before meal, specify the amount that the nutritional instructor may eat, and return the specified image to the requester. According to such an aspect, the client can limit the amount of meal by seeing the returned image, and can prevent the client from excessive intake of nutrition.

(4) The meal image and the test meal image transmitted from the requester may be the same food taken from different angles. By photographing the same food from different angles, the amount of food in the photographed image can be grasped more accurately.

(5) In the nutrition management support system described above, prizes, prize money, etc. may be provided to nutritional leaders with high nutritional capacity calculation capabilities. As a result, it is possible to give more incentives to the nutritional instructor to increase the nutritional amount calculation ability.

(6) Although the above-described embodiment is a nutrition management support system for supporting nutrition management of a person who receives dietary guidance, the present invention is a person who aims to be a nutritional instructor or a nutritional instructor (for example, a nutrition specialist) It can be applied to a nutrition management ability training system that trains the nutrition management ability of school students). Hereinafter, an embodiment in which the present invention is applied to a nutrition management ability training system will be described.
FIG. 17 shows the overall configuration of the nutrition management ability training system. As shown in FIG. 17, the nutrition management ability training system of the present embodiment is connected to a user terminal 100 operated by a user who receives training, and the user terminal 100 via a communication line (for example, the Internet, LAN, etc.). The management computer 130 is configured.

  As the user terminal 100, a commercially available personal computer can be used. There is no restriction | limiting in particular about the installation place of the user terminal 100, For example, it can install in a user's home etc. Or when this system is introduced into a nutrition school, it can be installed in a self-study room of a nutrition school. The user terminal 100 is equipped with a display and an input device (keyboard, mouse, etc.). A meal image transmitted from the management computer 130 is displayed on the display, and the user can make various inputs using an input device.

The management computer 130 includes a transmission / reception device 31 that transmits and receives data between the host computer 132 and the user terminal 100, and files 134, 135, 136, and 138 that store various data.
The host computer 132 transmits the meal image to the user terminal 100, receives the calculated nutrient amount returned from the user terminal 100, calculates the calculation accuracy using the received calculated nutrient amount, and uses the calculated calculation accuracy A process such as a reply to the person terminal 100 is performed.

  The result file 134 stores the training results of those who receive training using this system. FIG. 19 shows an example of the result file 134. As shown in FIG. 19, the performance file 134 stores, for each user, its ID, overall ranking, calculation accuracy for each classification (classification in which food is nutritionally classified), and the like. The record file 134 also stores a history of meal images transmitted to each user, and is programmed so that the same meal image is not frequently transmitted to the same user.

The meal image file 136 stores a meal image obtained by photographing a meal (cooking) in which a nutrition amount (total calories, protein) is measured in advance. As shown in FIG. 18, the meal image file 136 stores a single meal image obtained by photographing a single dish and a set meal image obtained by combining a plurality of dishes. Single meal images are classified according to the type of food, such as cereals images, meat, fish, eggs, and soy products images. In addition, the meal image file 136 stores a plurality of images that have been photographed or edited with respect to the same dish while changing the size, angle, brightness, definition, or the like.
The nutrition amount file 135 stores the total calories (kcal) and protein (g) of the meal image for each meal image stored in the meal image file 136.

  The meal content evaluation file 138 is a file for determining whether or not the change of the meal content performed by the user in the practical training of the system described later is appropriate. An example of the meal content evaluation file 138 is shown in FIG. As shown in FIG. 20, when the combination of ingredients is inappropriate (combination of ingredients a and b), or when the ingredient and cooking method are inappropriate (combination of ingredients c and cooking (that is, cooking ingredient c is cooked). Then, since the nutrient of the food material c will be destroyed)) etc. are memorized. As will be described later, when the meal content is changed and the meal after the change corresponds to any combination stored in the meal content evaluation file 138, it is determined that the change of the meal content is inappropriate. The

  Next, the flow of processing when the user performs training in the above-described nutrition management ability training system will be described. In order to perform training in this system, the user first connects the user terminal 100 to the management computer 130, and from the user terminal 100, the type of training (Introduction, Beginner, Intermediate, Advanced, Practice) ). When the type of training is input from the user terminal 100, the management computer 130 causes the user terminal 100 to display an image corresponding to the input type of training.

(A) Introductory Training FIG. 21 shows the flow of processing when the user performs introductory training. In this system, since the introductory training is the nutritional value calculation of single dishes, as shown in FIG. 21, the user first selects the type of single dishes for training (S60).
When the user operates the user terminal 100 to select a cereal, the management computer 130 transmits a meal image of the cereal to the terminal device 100, and the terminal device 100 performs a nutritional nutrition calculation test (training). (S62). Similarly, when meat, fish, egg, and soy products are selected, a nutrition calculation test is performed for meat, fish, egg, and soy products (S64), and when fruits are selected, the nutrition of fruits A calculation test is performed (S66), and when milk / dairy products are selected, a nutrition calculation test is performed for milk / dairy products (S68). A nutrition calculation test is performed (S70), and when vegetables, seaweed, and konjac are selected, a nutrition calculation test for vegetables, seaweed, and konjac is performed (S72).

FIG. 22 shows the flow of processing of each test in steps S62, 64, 66, 68, 70, 72. Each test is the same except that the meal image displayed on the user terminal 100 is different.
As shown in FIG. 22, when each test is started, the management computer 130 reads past results and trends from the results file 134 based on the user's personal ID, and based on the read past results and trends. Ten meal images are selected, and the selected meal images are transmitted to the user terminal 100 (S80). For example, if the user selects a cereal test, the meal image is selected from the cereal meal image so that a part of the meal image that was incorrect in the past is included, and the selected meal image is used. To the user terminal 100.
When the meal image is transmitted from the management computer 130 to the user terminal 100, the user selects an input format of nutrition (S82). In the introductory training, it is possible to select whether the nutrient input is a numerical value input or an alternative input, and the user can freely select an input format.

When the numeric input format is selected, a single dish image is displayed on the user terminal 100 (S84). The user calculates and inputs the nutrient amount (total calories, protein, etc.) for the displayed single dish image (S86). When the nutrient amount is input to the user terminal 100, the input nutrient amount is transmitted to the management computer 130. The management computer 130 calculates an error rate (calculation accuracy), and the calculated error rate and correct answer are calculated by the user. It transmits to the terminal 100. At this time, the management computer 130 updates the result file 134 of the user using the calculated error rate. The user terminal 100 that has received the error rate and the correct answer transmitted from the management computer 130 displays the received error rate and the correct answer on the screen (S88).
Next, in the user terminal 100, it is determined whether or not the nutrition amount has been answered for all the ten meal images transmitted from the management computer 130 (S90). If no nutritional value has been answered for all 10 meal images (NO in S90), the process returns to step S84 and the processes from step S84 are repeated. If the nutrition amount is answered for all 10 meal images (YES in S90), the test is terminated as it is.

On the other hand, when the alternative format is selected, a single dish image and a plurality of choices showing the nutrition of the single dish are displayed on the user terminal 100 (S92). The user selects one option from the displayed options (S94). When an answer is selected on the user terminal 100, the answer is transmitted to the management computer 130. The management computer 130 determines whether or not the received answer is correct, and transmits the result to the user terminal 100. At this time, the management computer 130 updates the result file 134 of the user using the answer result. The user terminal 100 that has received the answer result transmitted from the management computer 130 displays the received answer result on the screen (S96).
Next, in the user terminal 100, it is determined whether or not the nutrition amount has been answered for all the ten meal images transmitted from the management computer 130 (S99). If the nutrition amount is not answered for all 10 meal images (NO in S98), the process returns to step S92 and the processes from step S92 are repeated. If the nutrition amount is answered for all 10 meal images (YES in S98), the test is terminated as it is.

When the above-described test is completed, the process returns to step S74 in FIG. 21, and the management computer 130 transmits the test result of the 10 questions, its evaluation, advice, and the like to the user terminal 100. The scoring result, evaluation, advice, etc. are displayed (S74). For example, if it is incorrect for the same meal image as in the past, the fact is displayed to alert the user. Or, if the user has a tendency to calculate a higher nutritional amount, point out that fact and advise them to accurately determine the size of the food.
In step S78, whether or not to retrain is displayed on the user terminal 100. If the user selects retraining (YES in step S78), the process returns to step S60. If the user does not select retraining (NO in step S78), the process ends.

(B) Beginner level training FIG. 23 shows a flow of processing when a user performs an elementary level training. As is clear from the figure, the beginner level training is performed in the same procedure as the introductory level training. That is, as shown in FIG. 23, the user first selects a single dish for training (S100). When the user chooses a single dish (grain, meat / fish / egg / soy products, fruits, milk / dairy products, oil / fat, vegetables / seaweed / konjac) The selected single dish calculation training is performed (S102, 104, 106, 108, 110, 112).

FIG. 24 shows the flow of each test process in steps S102, 104, 106, 108, 110, and 112. Each test is the same except that the meal image displayed on the user terminal 100 is different.
As is clear from the flowchart shown in FIG. 24, the beginner level test is performed in substantially the same procedure as the introductory level test. However, in the beginner level test, the user terminal 100 displays a plurality of images having different sizes, amounts, orientations, brightness, and the like for the same single dish (S122, S130). In the beginner's edition, by changing the size, amount, orientation, and brightness of a single dish image displayed on the user terminal 100, it is possible to develop the ability to determine the size and amount of ingredients from the image.

When the tests in steps S102, 104, 106, 108, 110, and 112 are completed, the process returns to step S114 in FIG. 23, and the management computer 130 transmits the test scoring result, its evaluation, advice, and the like to the user terminal 100. The user terminal 100 displays the scoring result / evaluation / advice transmitted from the management computer 130 (S114).
In step S116, whether or not to retrain is displayed on the user terminal 100. If the user selects retraining (YES in step S78), the process returns to step S100, and if the user does not select retraining (NO in step S78), the process ends.

(C) Intermediate Level Training FIG. 25 shows the flow of processing when the user performs intermediate level training.
As shown in FIG. 25, in the intermediate training, first, the management computer 130 reads past results and trends from the results file 134 based on the user's personal ID, and based on the read past results and trends. Ten composite meal images are created by combining two or three types of single dish images, and the generated composite meal images are transmitted to the user terminal 100 (S138).
When the composite meal image is transmitted from the management computer 130 to the user terminal 100, the transmitted composite meal image is sequentially displayed on the user terminal 100 (S140). The user calculates and inputs a nutrient amount (total calories, protein, etc.) for the displayed synthetic meal image (S142). When the nutrient amount is input to the user terminal 100, the input nutrient amount is transmitted to the management computer 130. The management computer 130 calculates an error rate (calculation accuracy) from the received nutrient amount, and transmits the calculated error rate and correct answer to the user terminal 100. At this time, the management computer 130 updates the result file 134 of the user using the calculated error rate. The user terminal 100 that has received the error rate and the correct answer transmitted from the management computer 130 displays the received error rate and the correct answer on the screen (S144).
Next, in the user terminal 100, it is determined whether or not all ten composite meal images transmitted from the management computer 130 have been answered (S146). If the nutrient amount is not answered for all the 10 synthetic meal images (NO in S146), the process returns to step S140 and the process from step S140 is repeated. When the nutrition amount is answered for all the 10 synthetic meal images (YES in S146), the process proceeds to step S148.

In step S148, the management computer 130 transmits the test scoring result, its evaluation and advice, etc. to the user terminal 100, and the scoring result / evaluation / advice etc. transmitted from the management computer 130 to the user terminal 100. Is displayed (S148).
In step S150, whether or not to retrain is displayed on the user terminal 100. If the user selects retraining (YES in step S150), the process returns to step S138. If the user does not select retraining (NO in step S150), the process ends.
As is clear from the above explanation, in the intermediate training, the nutritional amount is calculated for the composite meal image in which two or three kinds of single dishes are combined. Get closer and develop more practical nutrition management skills.

(D) Advanced Level Training FIG. 26 shows the flow of processing when the user performs advanced level training. As shown in FIG. 26, the training for the advanced edition is performed in substantially the same processing procedure as the training for the intermediate edition (see FIG. 25). However, the advanced training is different in that the meal image transmitted from the management computer 130 to the user terminal 100 is a set meal image in which various nutrients are known in advance (see S152). For this reason, in step S156 of the advanced training, the user calculates and inputs various nutrients. In advanced training, users have to calculate various nutrients, so they can acquire more practical skills.

(E) Practical training FIG. 27 shows the flow of processing when a user performs practical training.
As shown in FIG. 27, in the practical training, first, the management computer 130 reads past results and trends from the result file 134 based on the user's personal ID, and nutrition balance based on the read past results and trends. Ten set meal images (however, various nutrients are known in advance) are selected, and the selected set meal images are transmitted to the user terminal 100 (S166).
When the set meal image is transmitted from the management computer 130 to the user terminal 100, the transmitted set meal image is sequentially displayed on the user terminal 100 (S168). The user changes the displayed meal image so that the nutritional balance is appropriate (S170). That is, the user designs the meal so that the nutritional balance is appropriate by changing the size of the displayed meal image or changing the ingredients so as to supplement the missing nutrients. In addition, the cooking method can be changed along with the change of the ingredients. The changed meal content is transmitted to the management computer 130.
When the management computer 130 receives a meal content change from the user terminal 100, the management computer 130 synthesizes a meal image based on the meal content change, and scores and evaluates the meal content change (S174). That is, the management computer 130 evaluates whether or not the nutrition content and nutrition balance of the changed meal content are appropriate, and the combination of the ingredients is an inappropriate combination stored in the meal content evaluation file 138. Judge whether it is applicable. For example, if the combination of ingredients used for the meal after the change corresponds to an inappropriate combination stored in the meal content evaluation file 138, the change of the meal content made by the user is inappropriate. Judge that there is.
Next, in the user terminal 100, it is determined whether or not the user has changed the meal contents for all the ten set meal images transmitted from the management computer 130 (S173). If the user has not changed the meal contents for all the set meal images (NO in S173), the process returns to step S168 and the processes from step S168 are repeated. If the meal content has been changed for all 10 set meal images (YES in S173), the process proceeds to step S174.

In step S174, the management computer 130 transmits the combined meal image after the change, the test scoring result, its evaluation, advice, and the like to the user terminal 100. The scoring result / evaluation / advice transmitted from 130 is displayed (S148). For this reason, the user can determine whether or not the changed meal is visually appropriate (that is, whether or not he / she wants to eat) from the changed meal image, and also from the viewpoint of nutrition amount and nutrition balance It can be determined whether or not it is appropriate, and further it can be determined whether or not the combination of ingredients is appropriate.
In step S176, whether or not to retrain is displayed on the user terminal 100. If the user selects retraining (YES in step S176), the process returns to step S166, and if the user does not select retraining (NO in step S176), the process ends.

In the above nutrition management ability training system, the size of ingredients is judged from meal images and the amount of nutrients is calculated, so the relationship between the size (amount) of ingredients and the amount of nutrition can be acquired, and more practical Can develop basic nutritional management ability.
Moreover, in the said nutrition management capability training system, the change of the meal content with respect to a meal with a bad nutrition balance can be performed virtually, and evaluation can be obtained about whether the change of the meal content was appropriate. As a result, it is possible to train a meal guidance ability (instructions such as changing meal contents) necessary for nutrition counseling or the like.

  In the above-described embodiment, the management computer 130 determines whether or not the calculated nutrient amount input from the user terminal 100 is correct (or calculation of the error rate), but these processes are performed by the user. You may make it perform with the terminal 100. FIG. For example, when the management computer 130 transmits a meal image to the user terminal 100, the management computer 130 also transmits the nutrition amount and the like of the meal image. When the nutrient amount is input for the meal image, the user terminal 20 determines whether the input nutrient amount is correct or calculates an error rate, and the management server 30 determines the determination accuracy or the calculated calculation accuracy. Send to. Even with such a configuration, it is possible to obtain the same effects as the above-described embodiment.

In the practical training described above, meals may be designed according to the type of illness or sick person. For example, the meal content may be changed (meal design) according to the type of infant, elderly person, diabetic patient, kidney disease patient, or the like.
Furthermore, in the method for changing the content of a meal, it is possible to add a supplement that supplements nutrients, and to determine whether or not the supplement is appropriate.

(7) Moreover, in the above-described nutrition management support system and nutrition management ability training system, the calorie content and the protein content are calculated from the meal image. However, the nutrients to be calculated are not limited to the calorie content and the protein content, but may be calculated for lipids and carbohydrates, and may be calculated for other nutrients as necessary.
