[0026] FIG. 4 is a flow chart for explaining the process of the nail evaluation device 1 shown in FIG. STEP ST11: The communication unit 55 of the nail evaluation device 1 receives image data and text data of the nails of the person to be evaluated from the terminal device 3 of the person to be evaluated, and stores them in the memory 59 in association with the identification information of the person to be evaluated.

[0027] STEP ST12: The communication unit 55 displays on the display 51 an image and text corresponding to the nail image data and text data acquired in step ST11. The evaluator looks at the nail image and text displayed on the display 51 and operates the operation unit 53 to input the evaluation of the evaluation subitems of each category. The processing unit 61 stores the input evaluation of the evaluation subitem in the memory 59 in association with the identification information of the person being evaluated.

[0028] STEP ST13: The processing unit 61 reads out the evaluations (data) of the evaluation sub-items from the memory 59, and for each item under evaluation, generates an evaluation of the item under evaluation based on the evaluations of the evaluation sub-items belonging to the item under evaluation, and stores the evaluation in the memory 59.

[0029] STEP ST14: The processing unit 61 reads out the evaluations (data) of the items being evaluated from the memory 59 , and for each evaluation category, generates an evaluation of the evaluation category based on the evaluations of the items being evaluated that belong to the evaluation category, and stores the evaluation in the memory 59 .

[0030] STEP ST15: The processing unit 61 reads out the evaluations (data) of the items being evaluated from the memory 59 , generates an overall evaluation based on the evaluations of each evaluation category, and stores the generated evaluation in the memory 59 .

[0031] STEP ST16: The processing unit 61 reads out from the memory 59 the sub-evaluation items stored in the memory 59 in step ST12, the intermediate evaluation items generated in step ST13, the evaluation categories generated in step ST14, and the overall evaluation generated in step ST15, and generates evaluation screen data to be displayed on the terminal device 3 of the person to be evaluated.

[0032] FIG. 5 is a diagram for explaining an example of a display on evaluation display screen 31 showing the evaluation results of a nail. As shown in FIG. 5, the evaluation display screen 31 has, for example, a sub-evaluation item display field 33, an item currently being evaluated display field 35, and an overall evaluation display field 37.

[0033] Figure 5 shows an example of care, but other evaluation categories can also be displayed in a similar way.

[0034] In the evaluation subitem display field 33, a plurality of evaluation subitems are arranged vertically in order, and the evaluation of each evaluation subitem is shown by a bar graph extending horizontally. The currently evaluated item display column 35 is located to the left of the sub-evaluation item display column 33 . In the currently evaluated item display field 35, the multiple currently evaluated items are arranged in order in the horizontal direction, and the evaluation of each currently evaluated item is shown by a bar graph extending vertically.

[0035] Furthermore, in the currently evaluated item display field 35, the previous evaluation is displayed in a line graph. In the sub-assessment item display field 33 and the ongoing evaluation item display field 35, the target evaluation value (passing value) is indicated, for example, by a red line.

[0036] Other evaluation methods using the nail evaluation device 1 will be described below. FIG. 6 is a flowchart for explaining another evaluation method in the nail evaluation device 1.

[0037] STEP ST21: When a required evaluation item does not reach a certain standard, the processing unit 61 of the nail evaluation device 1 performs a first evaluation in which the evaluation of the intermediate evaluation items and evaluation categories higher than the required evaluation item that does not reach the certain standard is given a failing evaluation (e.g., "1 point"), regardless of the evaluation of the other sub-evaluation items.

[0038] Furthermore, in the first evaluation, the processing unit 61 assigns, to each of the intermediate evaluation items, an evaluation that is equal to or lower than the lowest (minimum) evaluation of the mandatory evaluation sub-items subordinate to the intermediate evaluation item.

[0039] STEP ST22: In addition, the processing unit 61 performs a second evaluation in which the average of the evaluations of multiple evaluation sub-items subordinate to the evaluation item is used as the evaluation of the evaluation item in question, and the average of the evaluations of multiple evaluation sub-items subordinate to the evaluation category is used as the evaluation of the evaluation category in question.

[0040] STEP ST23: Then, the processing unit 61 identifies the smaller (lower) of the first evaluation and the second evaluation of the heavy machine.

[0041] STEP ST24: The processing unit 61 stores the evaluation identified in step ST23 in the memory 59 as an evaluation category and an evaluation of the item under evaluation.

[0042] In the above-described embodiment, images and text corresponding to the nail image data and text data were displayed on the display 51, and the evaluator visually viewed them and input an evaluation of the evaluation sub-items, but the processing unit 61 may also perform image analysis of the nail image to automatically generate some or all of the evaluation sub-items. That is, for the human evaluation items among the multiple evaluation sub-items that are evaluated by a person based on an image, the human evaluation input according to the operation of the person is used. Also, for the image analysis evaluation items among the multiple evaluation sub-items, the image analysis evaluation generated by the processing unit 61 by performing image analysis on the image acquired based on a predetermined criterion is used.

[0043] When the evaluation sub-items are associated with lesson materials (videos, etc.) or lesson plans, the processing unit 61 may provide or recommend materials or lesson plans to each person to be evaluated according to the evaluation content of the evaluation sub-items.

[0044] The processing unit 61 may provide or recommend the above-mentioned information in the following manner, for example. 1: Sell lesson videos for assignments. → Providing know-how and self-practice. 2nd: Propose online one-on-one lessons with a teacher who is good at solving problems (a teacher who has been judged to have a proven track record) or face-to-face one-on-one lessons with a PNA certified teacher closest to the user's home → Identify the habits that are the cause of the user's unique weaknesses in the problem items directly 3. Sales of 6-month intensive school (choice of online or face-to-face) We propose the instructors and curriculum best suited to solving your problems.

[0045] The processing unit 61 may analyze how the evaluation has changed after the person being evaluated has adopted the teaching materials (videos, etc.) or lesson plans, and may perform processing to make further suggestions. Additionally, the changes in each evaluation item of the person to be evaluated may be fed back to the lesson instructor. In addition, the instructors may be given incentives such as money for the improvement in the skills of the subjects after taking lessons from each instructor.

As shown in FIG. 10, the nail evaluation device 1 displays the overall evaluation on the display of the evaluation subject terminal device 3 in step ST16 shown in FIG. Based on the overall evaluation, the person being evaluated can know their own skill level as a nail artist. In addition, they can understand their strengths and weaknesses in each evaluation category.

[0050] The nail evaluation device 1 may also analyze the evaluations of the evaluation categories, intermediate evaluation items, and sub-items of the multiple registered evaluation subjects, and identify the strengths and weaknesses of each item, the progress of improvement according to the contents of the teaching materials and educational programs, etc. This provides information that can be used as a reference for improving the teaching materials and educational programs.

[0051] As described above, the nail evaluation device 1 makes it possible to objectively evaluate each item included in the nail technique (medium evaluation item, minor evaluation item, etc.). This makes it easy for the person being evaluated to further improve their nail skills based on the evaluation they received.

[0052] In addition, the nail evaluation device 1 can objectively prove the skill evaluation of each manicurist, which can be useful for nail salons when recruiting staff. Also, manicurists can advertise their own skill level.
