Description

Cooking skill determination method and program

This disclosure uses information such as operation history and operation history of household appliances such as rice cookers and microwave ovens, and AV (Audio Visual) appliances such as television receivers and recorders to determine the cooking skill of the user The present invention relates to a skill determination method and its program.

In recent years, AV home appliances such as television receivers (hereinafter referred to as “TVs”) or recorders that can be connected to the Internet have increased, and video distribution services such as movies or sports have been provided. In addition, household appliances called household appliances such as weight scales, activity meters, rice cookers, microwave ovens, refrigerators, etc. are also connected to the Internet. Thus, operation information or operation information of home appliances is transmitted to a server through the Internet, and the information is accumulated and analyzed by the server. In addition, various services are provided to users by using the analysis result of the server.

On the other hand, recipe search services provided by cooking equipment manufacturers, food manufacturers, or individuals are widespread. These recipe search services include a large number of recipes. For this reason, as one method of narrowing down recipes, recipes can be searched from various keywords or purposes. For example, ingredients, dish names, popularity rankings, seasons, cooking times, calories, or savings.

However, after searching for a target recipe, it is necessary to determine whether the user can cook with the user's cooking skill by checking the cooking content. When the cooking difficulty level of the recipe is higher than the user's cooking skill, there is a possibility that a situation in which cooking is not possible may occur. In this case, the recipe must be searched again. If the cooking difficulty level is set in the recipe, it is possible to search for a recipe that matches the user's cooking skill. For example, in patent document 1, when cooking by several persons, the content which shares a cooking process based on a user's age is described. Japanese Patent Laid-Open No. 2004-228561 describes contents for determining a user's cooking skill based on a cooking difficulty history of a previously cooked recipe and searching for a recipe that matches the cooking skill.

However, further improvements were necessary in the conventional configuration.

(Knowledge that became the basis of this disclosure)
Consider recipe search when multiple people with different cooking skills cook together. In the following, it is defined that a user whose cooking skill is “N” can cook a recipe or cooking process whose cooking difficulty level is “N”.

When searching for a recipe that can be cooked together by a user with a cooking skill of “N” and a user with a cooking skill of “less than N”, searching for a recipe with a cooking difficulty of “N” results in a cooking difficulty of Recipes configured by cooking steps of “N” or less are searched. However, it cannot be determined whether the cooking difficulty level includes less than “N”. That is, when a recipe with a high cooking difficulty level is searched for a person with a high cooking skill, a recipe that does not include any cooking process that can be cooked by a user with a low cooking skill may be searched. On the other hand, when a recipe with a low cooking difficulty level is searched according to a user with a low cooking skill, the recipes with a low cooking difficulty level are narrowed down. For this reason, the variation of the recipe obtained as a search result decreases. Thus, when one cooking difficulty level is set to a recipe, it is not suitable for a recipe search in the case of cooking by a plurality of people having different cooking skills.

On the other hand, the user's cooking skills vary among individuals even at the same age. For this reason, it is difficult to determine cooking skills based on age. Moreover, as described in Patent Document 2, it is conceivable to make a determination based on the cooking difficulty level of a recipe cooked in the past. However, in this case, if a user with high cooking skill intentionally continues to cook a recipe with a low cooking difficulty level, it is determined that the cooking skill is low. Furthermore, even if users with different cooking skills cook the same recipe, there is a possibility that a difference will occur in the way the cooking proceeds or the quality of the cooking. Therefore, it is difficult to determine the cooking skill only by the cooking difficulty level of the recipe.

Generally speaking, a person with high cooking skills is said to have a good setup and skill. For example, when a cook with different cooking skills cooks the same cooking process, a person with high cooking skills can “promote efficiently without wasting time”, “quickly cut, mix or measure,” “ Shorten the cooking process or improve the efficiency of cooking by a number of methods such as “I rarely see recipes”, “I can pull out my hands”, “Use cooking equipment or utensils, have ingenuity and skill” Can be made. Thus, a person with high cooking skills is characterized by a short time required for each cooking step as compared with a low person, and can be said to be one standard for measuring cooking skills.

Therefore, in the present disclosure, the cooking skill is more appropriately determined based on the cooking time. Moreover, in this indication, the cooking recipe suitable for a cook's skill is searched. In the present disclosure, the cooking time used for cooking skill determination uses operation log information such as operation history and operation history of household appliances owned by the user and AV appliances without using a dedicated camera or measurement device. It is calculated.

Furthermore, in the present disclosure, by setting the cooking difficulty level for each cooking process, a recipe suitable for cooking together by a plurality of people having different cooking skills is searched.

One aspect of the present disclosure is:
A cooking skill determination method in a cooking skill determination system for determining a cooking skill of a cook,
An acquisition step of acquiring operation log information of the device operated by the cook during cooking and storing it in an operation log database;
An analysis step of analyzing the operation log information accumulated in the operation log database;
Based on the analysis result of the analysis step, a determination step of determining a cooking skill that is an ability when cooking by the cook;
Is provided.

According to this aspect, the cooking skill of the cook can be suitably determined based on the operation log information of the equipment operated by the cook during cooking.

In the above embodiment, for example,
In the analysis step, the cooking time of the cook may be calculated from the operation log information,
In the determination step, the cooking skill of the cook may be determined based on the cooking time.

According to this aspect, the cooking skill of the cook is determined based on the cooking time of the cook calculated from the operation log information. Therefore, the cooking skill can be suitably determined based on the cooking action actually performed by the cook. For example, when the cooking time is shorter than a preset threshold, the cooking skill of the cook may be improved.

In the above embodiment, for example,
In the acquisition step, operation log information of the first device operated by the cook during cooking and operation log information of the second device operated by the cook following the first device are acquired and the acquisition is performed. It may be accumulated in the operation log database,
In the analysis step, a time from an operation end time of the first device to an operation start time of the second device may be calculated as the cooking time.

According to this aspect, the time from the operation end time of the first device to the operation start time of the second device operated following the first device is calculated as the cooking time. Therefore, the cooking skill of the cook is determined based on the cooking time. Generally, a cook with high cooking skills who is familiar with the operation of the device is considered to have a short transition time from the operation of the first device to the operation of the second device. For this reason, a cooking skill can be determined suitably based on the said cooking time.

In the above embodiment, for example,
In the acquisition step, the first operation log information that is operation log information of the cooking appliance operated by the first cooker and the second operation that is operation log information of the cooking appliance operated by the second cooker. Log information may be acquired and accumulated in the operation log database;
In the analysis step, the cooking time of the first cook may be calculated from the first operation log information, and the cooking time of the second cook may be calculated from the second operation log information.
In the determination step, the cooking skill of the first cooker may be determined from the cooking time of the first cooker and accumulated in the operation log database,
In the determination step, based on the cooking skill of the first cook, the cooking time of the first cook, and the cooking time of the second cook stored in the operation log database, the second cooking The cooking skill of the cook may be determined.

According to this aspect, the cooking skill of the second cooker is based on the cooking skill of the first cooker accumulated in the operation log database, the cooking time of the first cooker, and the cooking time of the second cooker. Determined. For this reason, when the cooking time of the second cooker is approximately equal to the cooking time of the first cooker (for example, the difference between the cooking time of the second cooker and the cooking time of the first cooker is equal to or less than a preset threshold value. In this case, it is determined that the cooking skill of the second cooker is equal to the cooking skill of the first cooker. Thus, according to this aspect, the cooking skill determination result does not vary excessively between cooks whose cooking times approximate.

In the above embodiment, for example,
In the determination step, the cooking skill of the cook may be determined for each element related to cooking based on the analysis result of the analysis step.

According to this aspect, the cooking skill of the cook is determined for each element related to cooking based on the analysis result of the analysis step. Therefore, the cooking skill of the cook is determined in detail. As elements relating to cooking, for example, “cooking methods” such as “boil” and “bake” may be used. As cooking-related elements, for example, “use a knife” such as “sliced”, “random cut”, or “food” such as “fish”, “meat”, or “Japanese”, “Western”, “Chinese”, etc. “Cooking field” or “cooking field” such as “meal”, “confectionery”, “bread” may be used.

In the above embodiment, for example,
The cooking skill determination system may include a recipe database in which recipe information including recipes is accumulated, and the recipe may be divided into a plurality of cooking processes, each of the plurality of cooking processes being a single operation. The recipe information may include a cooking difficulty level that is set for each cooking step and represents the difficulty of cooking.
The cooking skill determination method is:
Based on the cooking skill of the cook determined in the determination step, a recipe in which a cooking difficulty level at which the cook can cook all the cooking steps is set from the recipe information accumulated in the recipe database. There may be further provided a search step for searching for.

According to this aspect, based on the cooking skill of the cook, a recipe in which the cooking difficulty level that allows the cook to cook all the cooking steps is searched from the recipe information accumulated in the recipe database. Therefore, the cook can select a recipe that can be cooked, regardless of which recipe is searched.

In the above embodiment, for example,
A step of obtaining the number of cooks may be further included,
In the search step, a recipe having a cooking difficulty level that allows the cook with the highest cooking skill to cook all the cooking processes is set from the recipe information accumulated in the recipe database. A recipe including one or more cooking steps in which a cooking difficulty level that can be cooked by a low cook may be searched.

According to this aspect, it is possible to search for a recipe that allows a plurality of cooks having different cooking skills to cook together.

In the above embodiment, for example,
It further includes a notification step of notifying all types of cooking difficulty levels set in the cooking process that constitutes the recipe searched in the search step, and the number of cooking processes in which the cooking difficulty level is set. Good.

According to this aspect, it is possible to notify the cook of the distribution of the cooking difficulty level of the cooking process constituting the recipe.

In the above embodiment, for example,
You may further provide the notification step which notifies the said cooking process which comprises the said recipe searched at the said search step, and the cooking difficulty each set to the said some cooking process.

According to this aspect, it is possible to determine the cooking process that each cook is responsible for based on the notified plurality of cooking processes and the cooking difficulty level set for each cooking process.

In the above embodiment, for example,
In the notification step, the cook having cooking skills that can be cooked for each cooking process may be notified. According to this aspect, the cooking process which each cook takes charge can be determined easily.

Note that each of the embodiments described below shows a specific example of the present disclosure. Numerical values, shapes, components, steps, order of steps, and the like shown in the following embodiments are merely examples, and are not intended to limit the present disclosure. In addition, among the constituent elements in the following embodiments, constituent elements that are not described in the independent claims indicating the highest concept are described as optional constituent elements. In all the embodiments, the contents can be combined.

The operation log information is not limited to these items and refers to all information that can be acquired from any device 101.

The operation log information may be provided directly to the cloud server 111 from a plurality of devices 101 via the Internet. Alternatively, the operation log information may be once accumulated in the home gateway 102 from a plurality of devices 101 and provided to the cloud server 111 from the home gateway 102.

Next, the cloud server 111 of the data center operating company 110 provides the collected operation log information to the service provider 120 in a certain unit. Here, the “certain unit” may be a unit that can organize and provide the information collected by the data center operating company 110 to the service provider 120, or may be a unit requested by the service provider 120. Although described as “a certain unit”, the amount of information may not be constant. For example, the amount of information to be provided may change depending on the situation. The operation log information is stored in the server 121 held by the service provider 120 as necessary (arrow (b) in FIG. 1A).

Then, the service provider 120 organizes the operation log information into information suitable for the service provided to the user and provides it to the user. The user to be provided may be a user 10 using a plurality of devices 101 or an external user 20. The service providing method to the user may be provided directly to the

users

10 and 20 from the service provider 120 (arrows (f) and (e) in FIG. 1A), for example. The service providing method for the user may be provided to the user 10 through the cloud server 111 of the data center operating company 110 again (arrows (c) and (d) in FIG. 1A). In addition, the cloud server 111 of the data center operating company 110 may organize the operation log information into information suitable for the service provided to the user and provide the service provider 120 with the information.

Note that the user 10 and the user 20 may be different or the same.

9A to 9C are diagrams showing examples of cooking information 13000 stored in the recipe DB 728. FIG. The cooking information 13000 includes information on the cooking method and the cooking difficulty level. Specifically, the cooking information 13000 includes a recipe ID 1300, a recipe name 1301, a cooking difficulty level distribution 1302, a representative cooking picture 1303, a cooking step 1304, a cooking difficulty level 1305, a cooking method 1306, and a cooking picture 1307.

Recipe ID 1300 is a unique identifier for managing recipes. The recipe name 1301 is the name of the dish. In the example of FIG. 9A, for example, the name of the dish whose recipe ID 1300 is “0001” is “meat potato”, and the name of the dish whose recipe ID 1300 is “0002” is “boiled hamburger”.

The cooking difficulty level distribution 1302 indicates the distribution of the cooking difficulty level set in each cooking step 1304 in the corresponding recipe. First, the cooking difficulty level 1305 will be described. The cooking difficulty level 1305 is a numerical value of the difficulty of cooking in the cooking step 1304. In this embodiment, the number of steps of the cooking difficulty level 1305 matches the number of steps of the cooking skill 805. The cooking difficulty level 1305 corresponds to the cooking skill 805. For example, a cooking process whose cooking difficulty level 1305 is “3” indicates that a cook whose cooking skill 805 is “3” or more can cook. In the user information 8000 of the user DB 725 in FIG. 4, the cooking skill 805 is set in five stages. For this reason, in the example of the cooking information 13000 in FIGS. 9A to 9C, the cooking difficulty level 1305 is set to five levels.

However, the number of steps of the cooking difficulty level 1305 is not necessarily matched with the number of steps of the cooking skill 805. For example, the cooking difficulty level 1305 may be 10 levels and the cooking skill 805 may be 5 levels. In this case, a cook whose cooking skill 805 is “3” can cook the cooking process 1304 whose cooking difficulty level 1305 is “6” or less.

Next, the cooking difficulty level distribution 1302 will be described. For example, the cooking difficulty level 1305 is set in five levels, with the lowest being “1” and the highest being “5”. The cooking difficulty level distribution 1302 is data in which the cooking difficulty level 1305 and the number of cooking steps 1304 corresponding to the cooking difficulty level 1305 are linked and the cooking difficulty levels are linked in descending order from “5” to “1”. It is. In the example of FIGS. 9A and 9B, the cooking difficulty level distribution 1302 with the recipe ID 1300 “0001” is “05020401030002020101”. This is because the number of cooking steps 1305 is “5”, the number of cooking steps 1305 is “4”, the number of cooking steps 1305 is “3”, and the number of cooking steps 1305 is “0”. The number of cooking steps with a cooking difficulty level 1305 of “2” is one, and the number of cooking steps with a cooking difficulty level 1305 of “1” is one. In this embodiment, the cooking difficulty level 1305 matches the cooking skill 805 of the user information 8000 stored in the user DB 725, and is set in the same five levels.

The representative cooking photograph 1303 is a file name of a photograph showing a completed cooking state. For example, the representative cooking photograph 1303 whose recipe ID 1300 is “0001” is “FIG000106”. The cooking step 1304 represents the order in which the recipe is divided into a set of cooking units and the cooking units are cooked. For example, as shown in FIG. 9B, when the cooking process is divided into six, the cooking processes from cooking process 1 to cooking process 6 are set.

The cooking difficulty level 1305 is as described above. For example, as shown in FIG. 9B, when the recipe ID 1300 is “0001”, the cooking difficulty level 1305 of the cooking process 1 is “2”, the cooking difficulty level 1305 of the cooking process 2 is “1”, and the cooking process 3 The cooking difficulty level 1305 is “5”. The cooking method 1306 is text data representing, for example, a preparation method of ingredients, how to cut ingredients, set temperature / set time / operation procedure of the device, and the like.

The cooking photo 1307 is a photo taken when the corresponding cooking method 1306 is performed, a photo specifically showing the cooking method 1306, a photo such as reference material, or a file name of the material. For example, when the recipe ID is “0001”, the cooking photo of the cooking process 1 is “Fig000101”, and the cooking photo of the cooking process 2 is “Fig000102”. Moreover, the cooking photograph of the cooking process 3 is “NULL” and does not exist. Even if the cooking photo 1307 does not exist at present, if the cooking photo 1307 is to be taken in the future, the cooking photo may be additionally registered in the recipe DB 728. In this case, the corresponding file is stored in the cooking information 13000 of the recipe DB 728 as in FIGS. 9B and 9C. And the cook can acquire a photograph by referring to the file name.

FIG. 10 is a flowchart schematically showing the processing of the cooking skill determination system 700 configured as described above.

In step S1501, the cook operates the device 101 and cooks while holding the terminal 707. Alternatively, the cooker may set the device 101 using the terminal 707 and transmit the operation information from the terminal 707 to the device 101 to operate the device 101 and cook.

In step S1502, the cooker's terminal 707 transmits operation log information of the device 101 operated by the cooker in step S1501 to the server 121. Alternatively, the device 101 operated by the cook may transmit operation log information to the server 121 via the data center 203.

In step S1503, the server 121 transmits the cooker's terminal 707 or the cooker's device 101 in step S1502 from the cooker's terminal 707 or the device 101 via the data center 203 of the data center operating company 110. Operation log information is received (an example of an acquisition step).

In step S1504, the server 121 analyzes the operation log information received in step S1503, and determines the cooking skill 805 of the cook (an example of an analysis step and a determination step).

In step S1505, the server 121 includes at least one cooking step 1304 in which a cooking difficulty level 1305 that can be cooked by all the cookers is set according to the cooking skill 805 of the cook determined in step S1504. Is searched (an example of a search step).

In step S1506, the server 121 transmits the recipe information searched in step S1505 to the cooker's terminal 707 or to the device 101 used by the cooker via the data center 203 of the data center operating company 110.

Next, the details of each of the above steps will be described. In the following description, it is assumed that there are two cooks, a cook A and a cook B, as cooks.

FIG. 11 is a flowchart showing details of steps S1501 and S1502 in FIG.

In step S1601, the cook performs operation setting of the device 101 from the input / output unit 710 of the terminal 707 owned by the cook. A cook uses an application program provided by a device manufacturer or a Web page on a browser from the input / output unit 710 of the terminal 707 to set the operation of the device 101 on the terminal 707, and uses the device for cooking. The operation information 101 is input. For example, when the device 101 is a microwave oven, the cook inputs information regarding an operation such as a wattage of “600 W” and a warm-up time of “3 minutes” to the terminal 707.

In step S1602, the communication unit 711 of the cooker's terminal 707 transmits the setting information of the device 101 input by the cook in step S1601 and the cooker's terminal ID 803 to the device 101 used for cooking. At this time, the terminal 707 and the device 101 are communicably connected via short-range wireless communication or the Internet.

In step S1603, the communication unit 702 of the device 101 receives the setting information of the device 101 and the terminal ID 803 transmitted from the terminal 707 in step S1602.

In step S1604, the device 101 reads the operation information of the device 101 received in step S1603, and sets the operation item and state set in the operation information by controlling the input / output unit 701 of the device 101. The cook instructs the device 101 in which the operation information is set to start the operation. For example, the cook starts the operation of the device 101 by giving a start instruction by operating a start button or a switch displayed on the input / output unit 701 of the device 101.

In step S1605, when the communication unit 702 of the device 101 completes the operation started in step S1604 or when the state of the device 101 changes, the operation time 1201, operation information, and operation of the device 101 are recorded as operation log information. The terminal ID 1203 in which the information is set is transmitted to the server 121 via the data center 203 of the data center operating company 110.

In step S1606, the receiving unit 715 of the server 121 receives the operation log information transmitted by the device 101 in step S1605 (an example of an acquisition step).

Thus, steps S1501 and S1502 in FIG. 10 are executed.

FIG. 12 is a flowchart showing details of step S1503 in FIG.

In step S1701, in the server 121, the operation log acquisition unit 719 accumulates the operation log information received in step S1606 in the operation log DB 727 (an example of an acquisition step).

In step S1702, the cooker identifying unit 720 acquires the terminal ID 1203 from the operation log information accumulated in step S1701, and owns the corresponding terminal ID 1203 by referring to the user information 8000 stored in the user DB 725. Identify the cook to use. In the example of the operation log information 12000 in FIG. 8, the history ID 1200 is “0001” and the terminal ID 1203 is “0001”. Therefore, referring to the user information in FIG. 4, a cook whose terminal ID 803 corresponds to “0001” can be identified as a cook whose cooker ID 800 is “0001”.

In step S1703, the cooker specifying unit 720 acquires the cooking skill 805 possessed by the cook specified in step S1702 by referring to the user information 8000 stored in the user DB 725 (acquire number of cookers). Example of step). In the example of the user information 8000 in FIG. 4, it is understood that the cooking skill 805 corresponding to the cooker ID 800 “0001” is “4”.

In the first embodiment, in the server 121, the cooker specifying unit 720 specifies the cooker every time the receiving unit 715 receives the operation log information. Thereby, the cooker specifying unit 720 can determine whether or not cooking is performed by a plurality of cooks. In the example of the operation log information 12000 in FIG. 8, there are two types of terminal IDs having a terminal ID 1203 of “0001” and a terminal ID 1203 of “0002” at a series of operation times 1201 having the same date. Therefore, referring to the user information 8000 in FIG. 4, it can be seen that there are two cooks having a cooker ID 800 of “0001” and a cooker ID 800 of “0002”. As a result, the cooker identifying unit 720 recognizes that two cookers are cooking together.

FIG. 13 is a flowchart showing details of step S1504 in FIG.

In step S1801, the operation log analysis unit 721 acquires operation log information by the same cook from the operation log information that identifies the cook in step S1702 (an example of an analysis step). In the example of the operation log information 12000 illustrated in FIG. 8, a cook whose terminal ID 1203 is “0001” refers to the user information 8000 in FIG. 4, and the cook ID 800 is “0001”. The history ID 1200 of the corresponding cooker is “0001”, “0002”, “0003”, “0006”, “0009”, “0010”, and the operation log analysis unit 721 stores the history ID 1200 as operation log information. Get as.

Similarly, a cook whose terminal ID 1203 is “0002” in FIG. 8 is a cook ID 800 “0002” in FIG. The history ID 1200 of the corresponding cooker is that history ID 1200 is “0004”, “0005”, “0007”, “0008”, “0011”, “0012”, and the operation log analysis unit 721 stores them as operation log information. Get as.

In step S1802, the operation log analysis unit 721 calculates, as the cooking time 1400, for each cook operation acquired in step S1801, a time required for transition from operation of a certain device to operation of a different device ( An example of analysis step). For example, the time required from the operation of the device P to the operation of the device Q includes an operation time corresponding to the start of the operation of the device Q (for example, a heating start time of the microwave oven) and an operation time corresponding to the end of the operation of the device P (for example, a refrigerator It is calculated by the difference from the time when the door is closed. Similarly, the operation log analysis unit 721 calculates all different cooking times 1400 in all operation log information.

The reason for using the required time from the operation of a certain device to the operation of a different device as the cooking time 1400 is as follows. A cook who has high cooking skills is familiar with the order of the devices to be operated, and therefore it is considered that the time required for transition from operation of one device to operation of a different device is short. Conversely, a cook with low cooking skill, when the operation of a certain device is completed, confirms the next device to be operated by the recipe and then starts the operation of the next device. For this reason, it is considered that a cook with low cooking skills takes a long time to change from operation of a certain device to operation of a different device. Therefore, in the first embodiment, as the cooking time 1400, the time required for transition from operation of a certain device to operation of a different device is used.

In step S1803, cooking skill determination unit 722 calculates provisional cooking skill 1401 from the cooking time calculated in step S1802 (the time required for transition to operation of a device that is different from a certain device) (an example of a determination step). ). The provisional cooking skill 1401 is a temporary cooking skill that is determined only from device operation in a certain series of cooking. The provisional cooking skill 1401 is a cooking skill determined from, for example, cooking behavior at a certain day of dinner.

FIG. 14 is a diagram showing an example of skill determination criterion information 14000 stored in the operation log DB 727. The skill determination reference information 14000 represents a reference for the cooking skill determination unit 722 to determine the temporary cooking skill 1401 with respect to the cooking time 1400 calculated by the operation log analysis unit 721. In FIG. 14, the cooking time 1400 calculated by the operation log analysis unit 721 is represented by T. The reference values Ta1 to Ta5 are threshold values for determining the provisional cooking skill. The reference values Ta1 to Ta5 are determined so that Ta5 <Ta4 <Ta3 <Ta2 <Ta1.

In the example of FIG. 14, the provisional cooking skill 1401 is expressed in five stages. When the cooking time T is greater than the reference value Ta1, the cooking skill determination unit 722 determines that the temporary cooking skill is “1”. Similarly, when the cooking time T is equal to or less than the reference value Ta1 and greater than the reference value Ta2, the cooking skill determination unit 722 determines that the temporary cooking skill is “2”. Further, when the cooking time T is equal to or less than the reference value Ta4 and greater than the reference value Ta5, the cooking skill determination unit 722 determines that the temporary cooking skill is “5”. Note that, when the cooking time T is equal to or less than the reference value Ta4 without using the reference value Ta5, the cooking skill determination unit 722 may determine that the provisional cooking skill is “5”.

The cooking skill determination unit 722 determines the provisional cooking skill 1401 using the skill determination reference information 14000 of FIG. 14 for the cooking time 1400 for all operations performed by all the cooks specified in step S1801.

Returning to FIG. 13, in step S1804, the cooking skill determination unit 722 calculates the average value of all the temporary cooking skills 1401 determined in step S1803 for each cook.

In step S1805, the cooking skill determination unit 722 compares the average value of the temporary cooking skill 1401 calculated in step S1804 with the current cooking skill 805 of the corresponding cook acquired from the user DB 725 (an example of a determination step). ). When the average value of the provisional cooking skill 1401 (rounded down after the decimal point) matches the current cooking skill 805, the cooking skill determination unit 722 does not update the cooking skill 805. When the average value of the temporary cooking skill 1401 (rounded down after the decimal point) is different from the current cooking skill 805, the cooking skill determination unit 722 updates the cooking skill 805 to the value of the temporary cooking skill 1401. That is, the cooking skill determination unit 722 rewrites the value of the cooking skill in the user DB 725 to the average value of the temporary cooking skill 1401 (rounded down after the decimal point).

For example, when the average value of the temporary cooking skill 1401 of the cook whose cooker ID 800 is “0001” in FIG. 4 is calculated as “4”, the current cooking skill 805 is “4”. The average value matches the current cooking skill 805. For this reason, the cooking skill determination unit 722 does not update the cooking skill 805. When the average value of the temporary cooking skill 1401 of the cook whose cooker ID 800 is “0002” is calculated as “3”, the current cooking skill 805 is “2”, and the average value of the temporary cooking skill 1401 is The current cooking skill 805 does not match. For this reason, the cooking skill determination unit 722 updates the cooking skill 805. That is, the cooking skill determination unit 722 rewrites the cooking skill 805 of the user DB 725 from “2” to “3”.

In addition, when one recipe is cooked by a plurality of cookers, the cooking work is shared. For this reason, cooking time 1400 becomes long from a viewpoint unrelated to cooking skill 805. For example, a recipe in which the cooking process is set according to the procedures of 1, 2, and 3 is cooked by two persons, a cook A and a cook B, and the cook A performs the cooking process 1 and the cooking process 3 in the cooking process 2. Consider the case where cook B cooks. The cooking time from the cooking process 1 to the cooking process 3 of the cook A is also added to the time for the cook B to cook the cooking process 2. For this reason, it is determined that the cooking time 1400 is long and the temporary cooking skill 1401 is low. In order to avoid this, the operation log analysis unit 721 considers the operation log of the cook who cooks together when calculating the cooking time 1400, and the cooking process 2 is a time for cooking by a cook other than the cook A. Recognize and calculate the appropriate cooking time 1400 for cook A.

FIG. 15 is a flowchart showing details of step S1505 in FIG.

In step S1901, in the server 121, the recipe search unit 723 acquires the cooking skill 805 of the cooker ID 800 determined in step S1805 from the user information 8000 (FIG. 4) stored in the user DB 725. When there are a plurality of cooks, the recipe search unit 723 acquires the cooking skills 805 of all the cooks in the same manner.

In step S1902, the recipe search unit 723 searches the recipe information stored in the recipe DB 728 for a recipe that can be cooked based on the cooking skill 805 of the cook acquired in step S1901.

First, when there is one cook, the recipe search unit 723 compares the cooking skill 805 of the cook with the cooking difficulty distribution 1302, and finds a recipe ID 1300 that includes only the cooking difficulty 1305 of the cooking skill 805 or less. Search for. For example, when the cooking skill 805 of the cooker is “3” in five stages from “1” to “5”, the recipe search unit 723 includes a recipe including cooking steps 1304 having a cooking difficulty level 1305 of “3” or less. Search for.

Next, when there are two or more cookers, the recipe search unit 723 compares the cooking skill 805 of the cooker with the cooking difficulty distribution 1302, and is configured with a cooking difficulty level 1305 of the highest cooking skill 805 or less. And the recipe ID 1300 including at least one cooking step with the cooking difficulty level 1305 of the lowest cooking skill 805 or less is searched.

For example, there will be described a case where there are two cooks, cook A and cook B, cooking skill 805 of cook A is “4”, and cooking skill 805 of cook B is “2”. In this case, the recipe search unit 723 compares the cooking skill 805 and the cooking difficulty distribution 1302, and the cooking difficulty 1305 corresponding to the highest cooking skill 805 is configured by the cooking process 1304 having “4” or less, and the most. A recipe ID 1300 including at least one cooking step 1304 having a cooking difficulty level 1305 corresponding to the low cooking skill 805 of “2” or less is searched.

Specific examples of the above-described cookers A and B will be described using cooking information 13000 stored in the recipe DB 728 of FIG. 9A. For example, when the recipe ID 1300 is “0001”, the cooking difficulty level distribution 1302 includes two cooking steps 1304 with a cooking difficulty level 1305 of “5”, which is higher than “4”, which is the highest cooking skill 805. A cooking step 1304 of degree 1305 is included. That is, the recipe with the recipe ID 1300 “0001” includes the cooking process 1304 that the cook A cannot cook, and thus does not meet the search condition.

For example, a recipe with a recipe ID 1300 “0003” does not include a cooking step 1304 with a cooking difficulty 1305 higher than “4” that is the highest cooking skill 805 and “2” that is the lowest cooking skill 805. Since the following cooking difficulty level 1305 includes one cooking step 1304 of “2”, the search condition is met.

For example, the recipe with the recipe ID 1300 “0008” does not include the cooking step 1304 with the cooking difficulty level 1305 higher than “4”, which is the highest cooking skill 805, but the lowest cooking skill 805. A cooking step 1304 of “2” and “1” having a cooking difficulty level 1305 of “2” or less is not included at all. That is, the recipe with the recipe ID 1300 “0008” does not meet the search condition because there is no cooking process 1304 in which the cook B can cook.

As described above, in the case of the above-described cookers A and B, in the example of FIG. 9A, the recipe search unit 723 searches for recipes having recipe IDs 1300 “0003”, “0005”, and “0007” that meet the conditions. The

In step S1903, the recipe search unit 723 acquires the recipe ID 1300 searched in step S1902. The recipe search unit 723 notifies the display control unit 724 of the acquired recipe ID 1300.

By the above procedure, the recipe search unit 723 searches the recipe DB 728 for a recipe that matches the cooking skill 805 of the cook.

FIG. 16 is a flowchart showing details of step S1506 in FIG.

In step S2001, in the server 121, the display control unit 724 uses the cooking information 13000 stored in the recipe DB 728, the recipe name 1301, the cooking difficulty distribution 1302, and the representative cooking photo corresponding to the recipe ID 1300 searched in step S1903. 1303 is acquired.

In step S2002, when there are a plurality of recipe IDs 1300 searched in step S1903, the display control unit 724 creates a recipe list by listing the recipe name 1301, the cooking difficulty distribution 1302, and the representative cooking photo 1303 acquired in step S2001. To do.

In step S2003, the display control unit 724 acquires the terminal ID 803 used or held by the cook from the user information 8000 (FIG. 4) stored in the user DB 725. Alternatively, the display control unit 724 may acquire the device ID 1202 used by the cook from the operation log information 12000 (FIG. 8) stored in the operation log DB 727.

In step S2004, the display control unit 724 notifies the transmission unit 716 of the recipe list created in step S2002 and the terminal ID 803 acquired in step S2003. The transmission unit 716 transmits the recipe list to the terminal 707 corresponding to the terminal ID 803. In step S2003, when the device ID 1202 used by the cook is acquired, the display control unit 724 notifies the transmission unit 716 of the acquired device ID 1202. The transmission unit 716 transmits the recipe list to the device 101 corresponding to the device ID 1202.

In step S2005, in the terminal 707 used or owned by the cook, the

communication units

711 and 713 receive the recipe list transmitted by the transmission unit 716 in step S2004. In step S2004, when the recipe list is transmitted to the device 101, the communication units 702 and 704 of the device 101 used by the cook receive the recipe list.

In step S2006, the input /

(Embodiment 2)
In the first embodiment, the cooking skill determination unit 722 determines the temporary cooking skill using the skill determination reference information 14000 in FIG. However, the cooking skill determination method of the cooking skill determination unit 722 is not limited to the method using the skill determination reference information 14000 in FIG.

In Embodiment 2, the cooking skill determination unit 722 determines the cooking skill of the determination target cook using the operation log information of the cook whose cooking skill is higher than the cooking skill determination target cook.

The configuration of the cooking skill determination system 700 of the second embodiment is the same as that of the first embodiment shown in FIG. In the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals. In the following, the second embodiment will be described focusing on the differences from the first embodiment.

In Embodiment 2, the determination target of cooking skill is defined as cook K, and the cooking skill of cook K is defined as “2”. In the second embodiment, the cooking skill determination unit 722 compares the operation log information of the cooks A, B, and C whose cooking skill is “3” with the operation log information of the cook K, and the cook K Determine your cooking skills.

FIG. 22 is a diagram schematically showing the operation log information 2200 when the cook K performs cooking according to the recipe with the recipe ID “0035”. This operation log information 2200 is stored in the operation log DB 727 as in the first embodiment.

As shown in FIG. 22, the cook K has a terminal whose terminal ID 1203 is “0001”. And the cooker K is operating the apparatus in order of a refrigerator, an IH cooker, a microwave oven, a refrigerator, and an IH cooker according to the recipe whose recipe ID is “0035”.

The operation log analysis unit 721 calculates the cooking time of each cooking step from the operation log information 2200, as in the first embodiment. The cooking time is the time required from the operation end time of a certain device to the operation start time of a different device, as in the first embodiment.

When the cooking skill determination unit 722 determines the cooking skill of the cook K, the cooking skill determination unit 722 searches the operation log DB 727 to obtain operation log information when a cook whose cooking skill is higher than the cook K cooks the same recipe. Extract. Specifically, the cooking skill determination unit 722 operates log information when a cook whose cooking skill is “3”, which is one level higher than the cook K, cooks a recipe whose recipe ID is “0035”. To extract.

FIG. 23 is a diagram schematically showing operation log information 2300 when the cook A cooks a recipe with a recipe ID “0035”. FIG. 24 is a diagram schematically showing operation log information 2300 when the cook B cooks the recipe with the recipe ID “0035”. FIG. 25 is a diagram schematically showing operation log information 2300 when the cook C cooks a recipe with a recipe ID “0035”.

In the second embodiment, when the cooking skill determination unit 722 determines the cooking skill, the cooking skill determination unit 722 generates operation log information 2300 of the determined cooker, and accumulates the generated operation log information 2300 in the operation log DB 727.

The operation log information 2300 includes a cooking skill 805, a recipe ID 1300, a cooker ID 800, a cooking process 1304, a device ID 1202, an operation ID 1204, an operation time 1201, and a cooking time 2701 as shown in FIGS.

23 to 25, the cooking skills 805 of the cooks A, B, and C are “3”. As the recipe ID 1300, “0035” is stored, respectively, and it is clearly indicated that the operation log information is when the recipe with the recipe ID “0035” is cooked. “A”, “B”, and “C” are stored as the cook ID 800, respectively. As the cooking process 1304, “2”, “2”, “4”, “5”, “5”, “5”, “7”, and “8” are stored in order.

As the device ID 1202, “0001”, “0003”, “0003”, “0002”, “0002”, “0001”, “0001”, and “0003” are stored, respectively. As the operation ID 1204, “0002”, “0001”, “0001”, “0003”, “0002”, “0001”, “0002”, and “0003” are sequentially stored. The device ID 1202 and the operation ID 1204 in FIGS. 23 to 25 match the device ID 1202 and the operation ID 1204 from “0005” to “0011” of the history ID 1200 in FIG. 22, and are cooking of the same recipe. I understand.

As described above, the cooking time 2701 is the time required from the operation end time of a certain device to the operation start time of a different device. The cooking time 2701 is calculated by the operation log analysis unit 721. For example, “T01_A”, which is the uppermost operation time 1201 in FIG. 23, is the operation end time of the device whose device ID 1202 is “0001”. “T02_A” that is the operation time 1201 in the second row in FIG. 23 is the operation start time of the device whose device ID 1202 is “0003”.

Therefore, “T0102_A” which is the uppermost cooking time 2701 in FIG. 23 is calculated by the following equation.
T0102_A = T02_A-T01_A

Thus, in FIG. 23, cooking times T0102_A, T0203_A, T0405_A, and T0607_A are calculated in order as cooking time 2701 of cook A.

In FIG. 24, cooking times T0102_B, T0203_B, T0405_B, and T0607_B are calculated in order as the cooking time 2701 of the cook B. In FIG. 25, cooking times T0102_C, T0203_C, T0405_C, and T0607_C are calculated in order as the cooking time 2701 of the cook C.

The cooking skill determination unit 722 uses the operation log information 2300 of the cooks A, B, and C shown in FIGS. 23 to 25 and the operation log information 2200 of the cook K shown in FIG. Determine skills.

FIG. 26 is a flowchart illustrating a determination procedure by the cooking skill determination unit 722 according to the second embodiment. FIG. 27 is a diagram schematically illustrating a comparison procedure of cooking times between the cook K and the cooks A, B, and C. The determination process of the cooking skill determination unit 722 according to the second embodiment will be described with reference to FIGS.

26, first, the cooking skill determination unit 722 acquires the cooking skill of the cook K from the user DB 725 (step S2601). In the second embodiment, “2” is acquired as the cooking skill of the cook K. Next, the cooking skill determination unit 722 acquires the recipe ID cooked by the cook K from the recipe DB 728 (step S2602). In the second embodiment, “0035” is acquired as the recipe ID.

Subsequently, the cooking skill determination unit 722 includes the operation log information of the same recipe ID as the recipe ID cooked by the cook K among the operation log information of all the cooks having the cooking skill one level higher than the cook K. Obtained from the operation log DB 727 (step S2603). In the second embodiment, the operation log information 2300 of the cooks A, B, and C whose cooking skill is “3” shown in FIGS. 23 to 25 is acquired.

Next, the operation log analysis unit 721 calculates all cooking times from the operation time 1201 of the operation log information 2200 of the cook K in FIG. 22 (step S2604, an example of an analysis step). In the recipe with the recipe ID “0035”, as shown in FIG. 27, there are four types of cooking times “T0102”, “T0203”, “T0405”, and “T0607”. Therefore, four types of cooking time T0102_K, T0203_K, T0405_K, and T0607_K are calculated as the cooking time of the cook K.

In the second embodiment, as shown in FIGS. 23 to 25, the operation log information 2300 stored in the operation log DB 727 includes a cooking time 2701. Alternatively, the operation log information 2300 may not include the cooking time 2701. In that case, the operation log analysis unit 721 may calculate the cooking times of the cooks A, B, and C from the operation time 1201 of the operation log information 2300 in step S2604.

Next, the cooking skill determination unit 722 extracts the longest cooking time among the cooking times of the cooks A, B, and C as the maximum value of the cooking time in the four types of cooking times (step S2605). In the second embodiment, the following four formulas are used.
T0102_Max = max (T0102_A, T0102_B, T0102_C)
T0203_Max = max (T0203_A, T0203_B, T0203_C)
T0405_Max = max (T0405_A, T0405_B, T0405_C)
T0607_Max = max (T0607_A, T0607_B, T0607_C)

As a result, as shown in FIG. 27, four types of maximum cooking time values T0102_Max, T0203_Max, T0405_Max, and T0607_Max are extracted.

Next, as shown in FIG. 27, the cooking skill determination unit 722 compares each cooking time of the cook K with the maximum value of each cooking time, and each cooking time of the cook K It is determined whether or not it is equal to or less than the maximum time (step S2606, an example of a determination step). In the second embodiment, it is determined whether or not the following four expressions are satisfied.
T0102_K ≦ T0102_Max
T0203_K ≦ T0203_Max
T0405_K ≦ T0405_Max
T0607_K ≦ T0607_Max

If at least one of the above four expressions is not satisfied, the processing in FIG. 26 ends.

Next, when all the cooking times of the cook K are less than or equal to the maximum value of each cooking time, that is, when all the above four formulas are satisfied, the cooking skill determination unit 722 sets the temporary cooking skill of the cook K. Increase one step (step S2607, an example of a determination step). The cooking skill determination unit 722 executes steps S2601 to S2607 each time the cooker K cooks with a different recipe, and counts the number of times that the temporary cooking skill has increased by one step.

Subsequently, the cooking skill determination unit 722, when the number of times the temporary cooking skill has been increased (that is, the number of times that the temporary cooking skill has been determined to increase by one step in a different recipe) exceeds a preset number, The cooking skill is updated and increased by one level (step S2608, an example of a determination step). In the second embodiment, the cooking skill of the cook K increases from “2” to “3”.

In the second embodiment, in step S2606, the cooking skill determination unit 722 compares the cooking time of the cook K with the maximum cooking time of the cooks A, B, and C whose cooking skill is one step higher. . Alternatively, the cooking skill determination unit 722 may compare the cooking time of the cook K with a preset threshold value.

FIG. 28 is a diagram showing preset threshold values for comparing the cooking time of the recipe ID “0035” with the cooking time of the cooking skill determination target (cooker K in the second embodiment). In FIG. 28, a threshold value to be compared with a cooking skill determination target cooking time is set for each cooking time with a recipe ID “0035” and for each stage of the cooking skill.

For example, for a cooking time T0102 with a recipe ID “0035”, a threshold T0102_S1 with a cooking skill “1”, a threshold T0102_S2 with a cooking skill “2”, a threshold T0102_S3 with a cooking skill “3”, and cooking A threshold value T0102_S4 having a skill “4” and a threshold value T0102_S5 having a cooking skill “5” are set.

Since the cooking skill of the cook K is “2”, the cooking skill determination unit 722 compares the threshold of the cooking skill “3” with the cooking time of the cook K. That is, the cooking skill determination unit 722 determines whether or not the following four expressions are satisfied.
T0102_K ≦ T0102_S3
T0203_K ≦ T0203_S3
T0405_K ≦ T0405_S3
T0607_K ≦ T0607_S3

Also in this case, the cooking skill determination unit 722 may increase the temporary cooking skill of the cook K by one step when all of the above four formulas are satisfied.

(Cooking skill judgment parameters)
In the first and second embodiments, the cooking skill determination unit 722 uses the cooking time 1400, which is a required time from the operation end time of one device to the operation start time of the next device, as a parameter for determining cooking skills. . However, the present disclosure is not limited to this. The cooking skill determination unit 722 may determine the cooking skill using, for example, the following parameters.

(1) As a parameter obtained from the operation log information of the cooking appliance, the cooking skill determination unit 722 uses, for example, the time required for the cooking process, that is, the elapsed time from the use start time to the use end time of a certain cooking appliance. Also good. For example, a cook who has a short time between opening and closing the refrigerator door knows the necessary ingredients clearly and knows where the ingredients are stored, so cooking skills are considered high. . In addition, for example, when a food is heated, a cook whose cooking time is long due to the rough cutting of the food is considered to have low cooking skill even though the time during which the food is cut is equal.

Therefore, the cooking skill determination unit 722 may determine that the cooking skill is high when the time required for the cooking process is shorter than a preset threshold. Similarly, the cooking skill determination unit 722 may determine that the cooking skill is high when the total cooking time, that is, the total time of each cooking step is shorter than a preset threshold value.

(2) As a parameter obtained from cooking device operation log information, the cooking skill determination unit 722 may use, for example, the level of proficiency of cooking device operation. A cook whose operation time of the cooking appliance (for example, a required time from the setting start time of the microwave oven to the setting end time, that is, the heating start time) is shorter than a preset threshold is considered to have high cooking skills. In addition, a cooking skill is considered to be high for a cook who has fewer mistakes in operating the cooking device than a preset threshold value (for example, does not press a cancel button for canceling the setting or a button for returning the setting hierarchy to a higher hierarchy).

(3) As a parameter obtained from the operation log information of the cooking appliance, the cooking skill determination unit 722 may use, for example, the appropriateness of the heating and cooking in the cooking device. For example, if the difference between the temperature when the food is heated in the microwave oven, microwave oven, induction heating (IH) cooker and the temperature described in the recipe is less than a preset threshold, Since it can be estimated that the ingredients are heated in size, the cooking skill of the cook is considered high.

In this case, the comparison target is not limited to the temperature described in the recipe. For example, the operation log information stored in the operation log DB 727 may include a temperature transition during cooking. In this case, you may compare with the temperature in the operation log information of the cook whose cooking skill is higher than the cook whose judgment target is cooking skill.

(4) As a parameter obtained from the operation log information of the cooking device, the cooking skill determination unit 722 may use, for example, the appropriate timing of feeding the ingredients into the pan being heated by the cooking device. It is considered that the cooking skill of the cooker is high when the ingredients are put into the pan at an appropriate temperature that is smaller than a preset threshold value and the difference from the temperature described in the recipe. With regard to the determination of the input of the foodstuff, it can be determined that the foodstuff has been input when the temperature during the heating is remarkably reduced in a short time. Or you may judge that the foodstuff was thrown in when the mass of the pan during heating increased. The recipe describes the amount of ingredients or seasonings to be put into the pot. Therefore, if the increase width of the mass of the pan is used, it is possible to estimate which of the ingredients described in the recipe has been put into the pot.

(5) As a parameter obtained from the operation log information of the activity meter worn by the cook, the cooking skill determination unit 722 may include, for example, the length of the cooking flow line (for example, the length of the movement distance, the calorie consumption) Size, moving speed, etc.) may be used. These parameters can be said to relate to cooking time. For example, it is considered that the cooking skill of the cook whose movement distance is shorter than a preset threshold, calorie consumption is less than a preset threshold, or whose movement speed is higher than a preset threshold is high. As the activity meter, a portable device including an acceleration sensor and a timer may be used. When such a portable device is used, an average speed or a moving distance can be calculated from the detected acceleration and the measured time.

In addition, when a moving speed is used as a parameter, it can be compared with other cooks as it is. On the other hand, when the movement distance or the calorie consumption is used, the distance between the cooking appliances differs depending on the home, so it needs to be normalized. For example, you may measure the distance between main cooking appliances (for example, a refrigerator, IH cooker, a microwave oven, a cutting board, a tableware storage shelf). Alternatively, for example, the distance between the refrigerator and the microwave oven may be estimated from the acceleration and time from when the refrigerator door is closed to when the microwave oven is operated.

(6) As a parameter obtained from the operation log information of the recipe display device (for example, the terminal 707), the cooking skill determination unit 722 may use the length of the recipe viewing time. For example, it can be estimated that the cook whose recipe viewing time is longer than a preset threshold value is cooking while checking the recipe. For this reason, it is considered that such cooking skills are low. In this case, when the recipe is a page turning type, the display time of one page may be counted. When the recipe is a moving image, the viewing time may be counted.

(7) As a parameter obtained from the operation log information of the recipe display device (for example, the terminal 707), the cooking skill determination unit 722 may use a page feed mode of the recipe. For example, a cook whose page feed is slow and the viewing time of one page is longer than a preset threshold, a cook whose number of page returns is greater than a preset threshold, or a recipe that is a video is returned. Thus, it can be estimated that a cook whose number of operations to watch again is greater than a preset threshold value, while cooking while checking the contents of the recipe one by one. For this reason, it is considered that such cooking skills are low.

(8) As a parameter obtained from the operation log information of the recipe display device (for example, the terminal 707), the cooking skill determination unit 722 may use the number of types of cooked recipes. For example, a cook whose cooking recipe type is greater than or equal to a preset threshold value is considered to have high cooking skills. In this case, the cooking skill determination unit 722 may determine that the recipe that was viewed immediately before the operation of the cooking device was started is a cooked recipe. Alternatively, the cooking skill determination unit 722 may determine that the recipe that has been viewed when cooking is completed is a cooked recipe.

output units

710 and 712 of the terminal 707 shown in FIG.

FIG. 32 is a diagram showing an example of a search purpose selection screen 3200 displayed on the selection unit 3303. The search purpose selection screen 3200 of FIG. 32 is divided into four types of “skill improvement”, “mood”, “time margin”, and “visitor”. In “skill improvement”, one of “strengthen the strength” and “overcoming weakness” can be selected. When the cook selects “strengthen his / her strength”, the recipe search unit 723 searches the recipe DB 728 for a recipe including an element having high cooking skill of the cook. When the cook selects “overcoming weakness”, the recipe search unit 723 searches the recipe DB 728 for a recipe that includes an element having low cooking skill of the cook.

In “mood”, one of “fun” and “shindi” can be selected. When the cook selects “fun”, the recipe search unit 723 searches the recipe DB 728 for a recipe that includes an element whose cooking difficulty is higher than the cooking skill of the cook. When the cook selects “Shinjii”, the recipe search unit 723 searches the recipe DB 728 for a recipe that includes only elements whose cooking difficulty is equal to or lower than the cooking skill of the cook. This is because when the cook is not feeling well, it is considered that he / she does not want to perform cooking with a high cooking difficulty level.

In “Time margin”, either “Yes” or “No” can be selected. When the cook selects “Yes”, the recipe search unit 723 searches the recipe DB 728 for a recipe that includes an element whose cooking difficulty is higher than the cooking skill of the cook. When the cook selects “None”, the recipe search unit 723 searches the recipe DB 728 for a recipe that includes only elements whose cooking difficulty is equal to or lower than the cooking skill of the cook. This is because it is considered that cooking may take time when the cook has time.

In “Visitors”, one of “Yes” and “No” can be selected. When the cook selects “Yes”, the recipe search unit 723 searches the recipe DB 728 for a recipe that includes only elements whose cooking difficulty is equal to or lower than the cooking skill of the cook. When the cook selects “none”, the recipe search unit 723 searches the recipe DB 728 for a recipe that includes an element whose cooking difficulty is higher than the cooking skill of the cook. This is because when there are visitors, it is considered that they do not want to fail cooking.

29, the recipe display unit 3304 displays the recipe searched by the recipe search unit 723. As a specific configuration, the recipe display unit 3304 may be the input /

output units

The cooking skill DB 3305 stores the result of subjective evaluation input by the evaluator using the subjective evaluation input unit 3301. When the evaluator selects the completion button 3003 on the subjective evaluation input screen 3000, the result of subjective evaluation is stored in the cooking skill DB 3305. In addition, the cooking skill DB 3305 displays the cooking skills determined for each element by the cooking skill determination unit 722 for each cooker ID 800 (FIG. 4) in a table format such as a cooking skill display screen 3100 shown in FIG. save.

As described above, in Embodiment 3, the cooking skill determination unit 722 determines the cooking skill by element. Using the selection unit 3303, the cook selects a recipe search purpose such as “strengthen his / her strength” or “overcome weakness”. The recipe search unit 723 searches for a recipe suitable for the recipe search purpose selected by the cook based on the difference between the cooking difficulty level of the recipe and the cooking skill of the cook. As a result, according to the third embodiment, the cook can efficiently improve the cooking skill. In addition, the cook can search for a recipe that matches the purpose of each occasion, such as when busy, when free, or whether there is a visitor.

In Embodiment 3, the cooking skill determination unit 722 determines the cooking skill using the analysis result of the operation log analysis unit 721 and the subjective evaluation input by the subjective evaluation input unit 3301. Therefore, for example, even if the temporary cooking skill increases because the cooking time is short, if the subjective evaluation is low, the cooking skill determination unit 722 does not update the cooking skill. As a result, according to the third embodiment, the determination accuracy of cooking skills can be improved.

In the third embodiment, the cooking skill determination unit 722 may use, for example, the cooking skill of the cooker represented in five stages as an average value of cooking skills for each element. Or the cooking skill determination part 722 is good also considering the cooking skill of the cook shown, for example in five steps as the minimum value of the cooking skill according to an element.

Further, an automatic search button may be further displayed on the search purpose selection screen 3200 (FIG. 32) displayed on the selection unit 3303. When the automatic search button is selected, the recipe search unit 723 calculates the average value of the cooking skills for each element, and from the recipe DB 728 based on the five-level evaluation based on the average value, as in the first and second embodiments. You may search for a recipe.

Further, a skill improvement search button may be further displayed on the search purpose selection screen 3200 (FIG. 32) displayed on the selection unit 3303. When the skill improvement search button is selected, the recipe search unit 723 may search the recipe DB 728 for a recipe that has been cooked when another cooker has improved to one level of cooking skill. For example, when the skill improvement search button is selected by the cook K having the cooking skill “2”, the cook X having the cooking skill “3” is now improved from “2” to “3”. The cooked recipe is searched. In this case, for example, the recipe ID of the recipe cooked when the cooking skill is improved may be added to the user information 8000 (FIG. 4). Then, the recipe search unit 723 may search the recipe DB 728 for a recipe corresponding to the recipe ID included in the user information 8000.
