DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
(Device configuration)
First, an information providing apparatus according to the present invention will be described. FIG. 1 is a functional block diagram of an information providing apparatus according to an embodiment of the present invention. In FIG. 1, 1 is an intake nutrient amount storage unit, 2 is an ideal nutrient amount storage unit, 3 is a two-dimensional code reading unit, 4 is a contained nutrient recognition unit, 5 is a nutrient amount comparison unit, 6 is a dish determination unit, and 7 is It is a display means.

  The ingested nutrient amount storage unit 1 is a storage area in which nutrients taken by individuals are stored. The ideal nutrient amount storage unit 2 is a storage unit that stores an ideal nutrient amount that is an ideal intake amount of an individual nutrient. The two-dimensional code reading means 3 has a function of reading information recorded in the two-dimensional code. The contained nutrient recognition means 4 has a function of recognizing information when a dish (meal) and the contained nutrient amount for the meal are recorded in the two-dimensional code. The nutrient amount comparison means 5 has a function of comparing the intake nutrient amount stored in the intake nutrient amount storage unit 1 and the ideal nutrient amount stored in the ideal nutrient amount storage unit 2 to detect a deficient nutrient. ing. The dish determination unit 6 has a function of detecting a dish including the missing nutrient detected by the nutrient amount comparison unit 5 among the dishes recognized by the contained nutrient recognition unit 4. The display means 7 has a function of displaying detected nutrients and cooking information on the screen.

  The apparatus shown in FIG. 1 is realized by mounting a dedicated program on a portable terminal which is a portable terminal apparatus. Recently, mobile phones equipped with a display screen and equipped with a CCD camera and capable of executing a program are commercially available, and this is realized by installing a dedicated program in such a mobile phone. Note that the information providing apparatus according to the present invention is not necessarily realized by a mobile phone, and can be realized by another mobile terminal (for example, a PDA) equipped with these functions. However, recently, each individual has a mobile phone, and each mobile phone can hold the owner's information. Therefore, it is desirable to use the mobile phone.

  When this apparatus is realized using a mobile phone, the intake nutrient amount storage unit 1 and the ideal nutrient amount storage unit 2 can be realized by using a storage memory in the mobile phone. The two-dimensional code reading means 3 is realized by a CCD camera and a program for recognizing information read by the CCD camera as a two-dimensional code. When the information read by the CCD camera is a two-dimensional code, a means for recognizing information recorded in the two-dimensional code has already been realized and used in a mobile phone. The contained nutrient recognition means 4, the nutrient amount comparison means 5, and the dish determination means 6 are realized by executing a dedicated program unique to the present invention. The display means 7 can use a screen display unit of a mobile phone.

(Display)
Subsequently, a display object to which a two-dimensional code used in the present invention is added will be described. The display object is an object displaying various information. Here, a menu table that is a printed object on which a plurality of dishes are printed will be described as an example. FIG. 2 is a diagram showing an example of such a menu table. As shown in FIG. 2, a dish photo, an explanatory note, and a two-dimensional code are printed on the menu table for each dish.

  In FIG. 2, 21 is an overall description, 22 is an overall two-dimensional code, 23 is a dish photo, 24 is an instruction by dish, and 25 is a two-dimensional code by dish. The entire explanatory text 21 is an explanatory text related to the menu table shown in FIG. 2, and the cooking-specific explanatory text 24 is an explanatory text for each cooking. The whole two-dimensional code 22 is a two-dimensional code in which information about all dishes described in the menu table is recorded. The dish photo 23 is a printed photograph of each dish. The dish-specific two-dimensional code 25 is a two-dimensional code in which information about each dish is recorded. In the example of FIG. 2, six menu items are listed in the menu table, and only one overall explanation 21 and one entire two-dimensional code 22 are provided. Six sets of two-dimensional codes 25 for each dish are provided. In the present embodiment, a representative QR code is used as the two-dimensional code.

  Here, an example of information recorded in the two-dimensional code 25 for each dish is shown in FIG. In the present embodiment, the dish name and the amount of nutrients included in the dish are recorded in the two-dimensional code 25 for each dish. In the example of FIG. 3, the dish name “katsudon” and 12 types of nutrients from “calorie” to “salt” are recorded. As for other dishes, the dish name and nutrient amount of the corresponding dish are recorded in the two-dimensional code 25 for each dish. In addition, in the overall two-dimensional code 22, the names and nutrient amounts of all dishes posted on the page are recorded in association with each dish. For example, in the example of the menu table in FIG. 2, six pieces of recording information as shown in FIG. 3 are recorded in the entire two-dimensional code 22.

  Here, data recorded in the dish-specific two-dimensional code 25 will be described. The dish-specific two-dimensional code 25 may record the information shown in FIG. 3 directly converted into the two-dimensional code. However, the following method for reducing the data amount may be used. it can. Specifically, it is performed by recording only numerical values for the number of digits each numerical value can take. For example, it is converted into a format in which only numerical values are assigned and recorded, such as 4 digits for calories and 3 digits for salt. As a result, the recording information shown in FIG. 3 is converted as shown in FIG. In FIG. 11A, for convenience of explanation, an interval is provided for each digit number corresponding to each nutrient, but in reality, all are arranged continuously. In addition, in the recorded information shown in FIG. 11A, a one-digit code “4” is added to the end portion. This is because the information shown in FIG. This is an encryption number for specifying the encryption method to be converted. Since the encryption number can take 10 values from 0 to 9, up to 10 encryption methods can be prepared. As an encryption method, a method of replacing the first character every other character, a method of replacing the second character every other character, a method of replacing the first character every other character, and a method of inverting the order of arrangement from the beginning to the end Various things can be prepared.

  For example, in the example of FIG. 11A, the encryption number is “4”, which indicates a method of inverting the order of arrangement from the beginning to the end. Therefore, the recorded information after encryption by this method is as shown in FIG. Note that the cipher numbers are not changed in order in consideration of the time of decryption, and are still arranged at the end in FIG. 11B. Thus, it becomes difficult to decipher data by performing encryption.

  Further, instead of the recording information as shown in FIG. 11A, it is possible to use less data. In the data shown in FIG. 11A, since it is recorded with a character code, 8 bits are required for one digit. Therefore, numerical values are recorded as binary data. For example, if the number “1000” is input as a character code, 4 characters × 8 bits = 32 bits are required, but if it is recorded as binary data, only 10 bits are required. Furthermore, if the values that can be input are limited, the amount of data can be reduced. For example, if calories are set so that only one meal can be input from 0 kcal to 2047 kcal, the number of bits can be further saved.

(Preparation)
The user downloads a dedicated program to his / her mobile terminal (such as a mobile phone) to make it operable as a device as shown in FIG. 1, and then stores his / her ideal nutrient amount into the ideal nutrient amount storage. Record in Part 2. The ideal nutrient amount can be created by, for example, a dietitian based on age, sex, and physical characteristics (height, weight, etc.). An example of an ideal nutrient is shown in FIG. FIG. 9 shows an example of an ideal amount of nutrients (nutrient requirement) in the case of a male, 25 years old, a height of 170 cm, a weight of 63 kg, and a living activity intensity of 2. Life activity intensity is divided into four levels of daily life. Life activity intensity 2 is “walking, riding, customer service, housekeeping, etc. for about 2 hours by commuting, work, etc. In addition to the relatively large number of tasks, most of them are in the state of office work or talking in a sitting position. FIG. 10 shows a table for the daily activity intensity.

  For recording the ideal nutrient amount in the ideal nutrient amount storage unit 2, various methods such as direct input by key input can be used. However, in this embodiment, the compression of the data amount and the data are In order to make it difficult to decipher even if it leaks, the following method is used. First, the ideal nutrient amount is coded. For example, FIG. 12A shows data obtained by coding the ideal nutrient amount shown in FIG.

  Further, the data shown in FIG. 12A is encrypted by a method specified by the encryption number. For example, the method of the encryption number “4” shows a method of inverting the order of arrangement from the beginning to the end as in the case of the recording information to the two-dimensional code described above. The ideal nutrient amount is shown in FIG. Thus, it becomes difficult to decipher data by performing encryption.

  Further, instead of the data as shown in FIG. 12A, it is possible to make the data smaller. In the data shown in FIG. 12A, since a character code is used, 8 bits are required for one number. Therefore, numerical values are recorded as binary data. For example, if the number “1000” is input as a character code, 4 characters × 8 bits = 32 bits are required, but if it is recorded as binary data, only 10 bits are required.

(Processing operation of the device)
Next, the processing operation of the apparatus shown in FIG. 1 will be described. The user prepares the ideal nutrient amount in the ideal nutrient amount storage unit 2 and uses the two-dimensional code reading means 3 of his portable terminal to read the two-dimensional code 25 for each menu in the menu table shown in FIG. Read. Specifically, in a mobile phone, a process of photographing with a built-in CCD camera may be performed. Then, the contained nutrient recognizing means 4 recognizes the information recorded in the two-dimensional code in units of a predetermined number of digits, associates them with nutrients and the like that each numerical value means, and then displays them on the display means 7. At this time, if the information recorded in the two-dimensional code is binary information, it is converted into numerical information and then associated with nutrients and the like that each numerical value means. At this time, information as shown in FIG. 3 is displayed on the screen of the portable terminal. At the first time, since the information on the intake nutrients is not recorded in the intake nutrient amount storage unit 1, the nutrient amount comparison means 5 and the dish determination means 6 do not function. When the user orders and eats the food, the user gives an instruction to record the displayed information as an intake nutrient. Then, the displayed information is recorded in the intake nutrient amount storage unit 1. Since the user eats the ordered food, the user takes in nutrients almost equal to the nutrients read from the two-dimensional code 25 of the menu table as described above, and is recorded in the intake nutrient amount storage unit 1. The amount of nutrients consumed can be estimated as actually consumed by the user.

  After the second time, that is, after the intake nutrient amount is recorded in the intake nutrient amount storage unit 1, similarly to the above, when the user reads the dish-specific two-dimensional code 25 by the two-dimensional code reading means 3, Information recorded in the dimension code is displayed and recorded according to the user's instruction. After the intake nutrient amount is recorded in the intake nutrient amount storage unit 1, when the whole two-dimensional code 22 of the menu table shown in FIG. The intake nutrient amount recorded in the nutrient amount storage unit 1 and the ideal nutrient amount recorded in the ideal nutrient amount storage unit 2 are compared, and the intake nutrient amount is insufficient with respect to the ideal nutrient amount. Furthermore, the dish determination means 6 extracts the dish containing the most deficient nutrients detected by the nutrient amount comparison means 5 from the information read from the overall two-dimensional code 22, and recommends the dish as a recommended dish. Displayed on the display means 7. The state of the screen displayed at this time is shown in FIG. As shown in FIG. 4, the display means 7 lists the deficient nutrients detected by the nutrient amount comparison means 5 and displays the determined dish.

  When the user eats the recommended food displayed on the display means 7, as described above, the user instructs to record the nutrient amount of the displayed food, and the intake nutrient amount storage unit 1 Record as nutrient content.

(Indication of undernutrients only)
In the above example, the function to suggest recommended dishes from multiple dishes listed in the menu table based on undernutrients was explained. However, only recommended nutrients are displayed without suggesting recommended dishes. Is also possible. In this case, a predetermined operation button of the portable terminal is provided with a function for instructing the display of insufficient nutrients, and when the user operates this operation button, the nutrient amount comparison means 5 stores the intake nutrient amount memory. The ingested nutrient amount recorded in the unit 1 and the ideal nutrient amount recorded in the ideal nutrient amount storage unit 2 are compared to extract the ingested nutrient amount that is insufficient relative to the ideal nutrient amount, and the display means 7 Display the extracted nutrient deficiencies. As a display method, for example, as shown in FIG. 5, a comparison graph may be used, or a list may be displayed in order from nutrients with a large deficiency.

  In the example shown in FIG. 1, the ideal nutrient amount that is the ideal nutrient amount to be ingested and the ingested nutrient amount that is the actual ingested nutrient amount are recorded inside the mobile terminal. It is not necessary to do everything inside the terminal. Either one of the intake nutrient amount storage unit 1 or the ideal nutrient amount storage unit 2 is recorded inside the portable terminal, and the other is recorded on a server computer accessible via the network. It is also possible to record the both on the server computer.

(Example using GPS)
In recent years, mobile phones equipped with a GPS function and capable of detecting the present location have also appeared. By adopting a portable terminal having such a GPS function in this apparatus, it is possible to propose a restaurant dish corresponding to a lack of nutrients. In this case, it is necessary to access a server for providing a separate service via the network. First, the user accesses the server and transmits position information detected by the GPS function. Then, a restaurant category selection screen as shown in FIG. 8A is transmitted from the server. Furthermore, when the user selects, a store selection screen corresponding to the selected category is transmitted from the server. The screen at this time is shown in FIG. Here, when the user selects a store name, the portable terminal transmits the insufficient nutrient calculated by the nutrient amount comparison means 5 to the server. The server refers to the dish information recorded for the selected store, extracts the received dish information containing a large amount of deficient nutrients, and transmits it to the mobile terminal. As a result, a recommended dish as shown in FIG. 8C is displayed on the screen of the mobile terminal.

(Other examples of display items)
In the above-described example, the menu table that is a printed material on which a plurality of dishes are printed has been described as the display object. For example, as shown in FIG. 6, it is possible to adopt a form of a sticker to be attached to food. FIG. 6 is a plan view of the display object in the form of a seal as viewed from the front surface, and the back surface has an adhesive force by a known adhesive. In addition to the food name, content, price, etc., the surface is printed with how to make a dish using this food, and other ingredients necessary for making the dish. In addition, a bar code for food management is printed, and a two-dimensional code 61 is also printed. Information that cannot be displayed on the sticker is recorded in the two-dimensional code. The user can read the two-dimensional code with the two-dimensional code reading means 3 of the portable terminal even for such a seal. Then, as in the case of the menu table described above, the read nutrients are displayed, and are stored in the intake nutrient amount storage unit 1 when a recording instruction is given.

  Furthermore, in the two-dimensional code, information that cannot be displayed on the seal surface other than nutrients can be recorded. For example, in the example shown in the figure, feeds, producers, producer comments, and the like can also be recorded. Therefore, on the information providing side, it is possible to convey to the user information that cannot be displayed on a display object having a limited area.

  In addition, in the display shown in FIG. 2, the recipe is posted in the explanatory text, and the two-dimensional code includes the total calorie content of the recipe, the main nutrient amount (protein, carbohydrate, vitamin A, B, C, D, E, Record minerals, plant fibers, etc.). In this case, when photographing is performed with the mobile terminal, nutrients are displayed on the screen as shown in FIG.

  In addition, in the display shown in FIG. 2, a restaurant menu, a home delivery catalog, and a take-out lunch menu are included in the explanation, and the two-dimensional code includes an introduction of ingredients, an introduction of the cook, a recommendation sentence, and the menu. Record the total calories and main nutrients. In this case, when a picture is taken with a portable terminal, the screen introduces food, introduces a chef, and displays a recommendation sentence as shown in FIG. Further, nutrients are displayed by scrolling the screen.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the above embodiments, and various modifications can be made. For example, in the above-described embodiment, the case where the two-dimensional code is visible to the naked eye has been described. However, the two-dimensional code does not impair the design of the printed material, and thus the two-dimensional code is not visible to the naked eye. good. In other words, a transparent code or a two-dimensional code called print-type steganography, which is not visible to the naked eye but can be read by a two-dimensional code reading means such as a CCD camera, can also be employed.
