1. Field of the Invention

The present invention relates to a shoe purchase recommendation device that predicts a change in a foot size of a prediction target person and recommends purchase of shoes.

2. Description of the Related Art

It is desired to wear shoes having an appropriate volume suited to the foot size of a wearer, such as a foot length, a foot circumference, and an arch height, and wearing shoes having an inappropriate volume may cause hallux valgus or may cause a shoe blister. In particular, when the wearer is a child, wearing shoes having an inappropriate volume sometimes adversely affect the growth of the foot.

Since the foot size changes with growth and aging, even a shoe having an optimum volume for the current foot size will not have an optimum volume for the foot size in the future in some cases.

WO 2021/130889 A discloses an invention that predicts a change in a foot length and notifies a customer of a replacement purchase of shoes.

WO 2021/130889 A discloses that a change in a foot length is predicted and a customer is notified of a replacement purchase of shoes, but does not disclose a specific method for notifying of a replacement purchase opportunity. Therefore, in the invention disclosed in WO 2021/130889 A, a user is not allowed to know a purchase-recommended date, which is an appropriate timing for purchasing shoes.

The present invention has been made in view of the above, and an object of the present invention is to obtain a shoe purchase recommendation device capable of notifying a user of a purchase-recommended date, which is an appropriate timing for purchasing shoes.

SUMMARY OF THE INVENTION

In order to solve the above-described problem and achieve the object, a shoe purchase recommendation device according to the present invention includes a user data storage unit that stores user data including at least an age and a foot size measurement value of a user, a foot size change prediction unit that calculates a change prediction value of a foot size of the user on a basis of the user data; a product information storage unit that stores product information including a shoe size; a purchase recommendation processing unit that determines a purchase-recommended date and a purchase-recommended product of shoes on a basis of the change prediction value and the product information; and a screen display processing unit that performs processing of displaying the purchase-recommended date, the purchase-recommended product, and a measurement-recommended date for the foot size. The screen display processing unit emphasizes and displays the purchase-recommended date and the purchase-recommended product when a number of days until the purchase-recommended date becomes equal to or less than a predetermined number of days.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Hereinafter, embodiments of a shoe purchase recommendation device according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by these embodiments. In addition, in the embodiments to be described below, the same or common parts are denoted by the same reference signs, and the description thereof will not be repeated.

In the following description, a case where the foot size is the foot length will be taken as an example. However, the foot size only has to be dimensions of a measurable portion, such as a foot circumference and an arch height, and is not limited to dimensions of a specific portion. In addition, the foot size may be a combination of dimensions of different portions of the foot, such as the foot length, the foot circumference, and the arch height, or may be three-dimensional scan data of the user's foot. Furthermore, not only the whole size of the foot but also the dimensions of a part of the shoe corresponding to the foot length, the foot circumference, the arch height, or the like may be regarded as the foot size.

First Embodiment

FIG. 1 is a diagram illustrating a configuration of a shoe purchase recommendation device according to a first embodiment of the present invention. A shoe purchase recommendation device 10A includes: a user data storage unit 11 that stores user data 111 including at least an age 111A, a foot size measurement value 111B, and a foot size measurement date 111C of a user; a foot size change prediction unit 12 that calculates a change prediction value of a foot size of the user on the basis of the user data 111; a product information storage unit 13 that stores product information 131 including a shoe size 131A and a product image 131B; a purchase recommendation processing unit 14 that determines a purchase-recommended date and a purchase-recommended product of shoes on the basis of the change prediction value and the product information 131; and a screen display processing unit 15 that performs processing of displaying a normal notification screen, to be described later, containing the purchase-recommended date, the purchase-recommended product, and a measurement-recommended date for the foot size, and an emphasis notification screen, to be described later, that emphasizes and displays the purchase-recommended date and the purchase-recommended product. The foot size measurement value 111B is a measurement value of the foot size of the user measured in the past. The foot size measurement date 111C is a date on which the foot size was measured in the past. The age 111A is data representing elapsed time from birth. The age 111A may be in “month old” representing the elapsed time from birth in units of months, instead of units of years.

The foot size change prediction unit 12 holds a foot size change table 121, which is statistical data of changes in the foot size, and calculates a change prediction value of the foot size by adding an average change amount of the foot size based on the age 111A to the foot size measurement value 111B. The foot size change prediction unit 12 can calculate not only the prediction value of the foot size at a future time point dependent on the current foot size measurement value 111B as a basis, but also the prediction value of the foot size at a past time point dependent on the past foot size measurement value 111B as a basis. Note that the foot size change prediction unit 12 may calculate the change prediction value of the foot size by adding the change amount of the foot size based on data of the foot size of an older family member of the user included in the user data 111 stored in the user data storage unit 11, to the foot size measurement value 111B.

In addition to the age 111A, the foot size measurement value 111B, and the foot size measurement date 111C, the user data 111 may include the height, weight, gender, residential region, current foot size data of the family member, and past foot size data of the family member. The foot size change prediction unit 12 calculates the change prediction value of the foot size using these pieces of information, whereby the change prediction value can be calculated by more accurately predicting the change in the foot size. In the shoe purchase recommendation device 10A according to the first embodiment, the user data 111 includes a height 111G and a weight 111H of the user. Therefore, by calculating the change prediction value of the foot size using the age 111A, the height 111G, and the weight 111H of the user and the foot size measurement value 111B at the time point of the input age, the foot size change prediction unit 12 can calculate the foot size prediction value in consideration of the physique of the user.

A display input device 20 including a display unit 21 and an input unit 22 is connected to the shoe purchase recommendation device 10A. A liquid crystal display or an organic electroluminescence display can be applied as the display unit 21, but a display device other than these displays may be adopted. Input devices such as a keyboard and a pointing device can be applied as the input unit 22, but an input device other than these input devices may be adopted. Note that a touch screen monitor having both of a display function and an input function together can also be applied as the display unit 21 and the input unit 22. The display input device 20 is connected to the shoe purchase recommendation device 10A via the Internet. Note that the display input device 20 may be directly connected to the shoe purchase recommendation device 10A not via the Internet. In addition, the shoe purchase recommendation device 10A may include the display unit 21 and the input unit 22. In this case, the display input device 20 does not have to be connected to the shoe purchase recommendation device 10A.

A foot size measuring device 30 is connected to the shoe purchase recommendation device 10A. The foot size measuring device 30 outputs the foot size measurement value 111B and the foot size measurement date 111C obtained by measuring the foot size of the user. The foot size measurement value 111B and the foot size measurement date 111C are accumulated in the user data storage unit 11. Note that the shoe purchase recommendation device 10A may be provided with a user interface for input such that the foot size measurement value 111B and the foot size measurement date 111C are input by operating the user interface. In addition, the shoe purchase recommendation device 10A may acquire the foot size measurement value 111B and the foot size measurement date 111C by communicating with another device that stores the foot size measurement value 111B and the foot size measurement date 111C. Furthermore, the foot size measurement date 111C does not have to be data separated from the foot size measurement value 111B and may be data of creation date and time or update date and time included in the file property of the foot size measurement value 111B.

To give an example, a server of a shoe manufacturer can be applied as the shoe purchase recommendation device 10A. In addition, a smartphone terminal of the user can be applied as the display input device 20. Furthermore, a three-dimensional foot last automatic measuring instrument or an information terminal such as a smartphone terminal and a tablet terminal of the user can be applied as the foot size measuring device 30.

The shoes are set with a foot size fitting range for each size. To give an example, for a certain shoe having a size of 20 cm, a foot length of 19.15 cm to 19.56 cm is set as the foot size fitting range. Accordingly, the day on which the foot length of the user reaches 19.15 cm is the purchase-recommended date on which the purchase of the shoes having a size of 20 cm is recommended. In this manner, the purchase recommendation processing unit 14 determines the day on which the change prediction value of the foot size of the user reaches the foot size fitting range of shoes that are the purchase target recommended product, as the purchase-recommended date.

The screen display processing unit 15 sets the day on which a preset period elapses from the previous foot size measurement date 111C, as the measurement-recommended date.

FIG. 2 is a diagram illustrating an example of the normal notification screen displayed by the screen display processing unit of the shoe purchase recommendation device according to the first embodiment. A normal notification screen 200 contains a measurement-recommended date display area 201 in which the measurement-recommended date is displayed, a purchase recommendation display area 202 in which the purchase-recommended date and the purchase-recommended product are displayed, a message display area 203 in which a message for the user is displayed, and a previous measurement information display area 204 in which the most recent foot size measurement date 111C and foot size measurement value 111B are displayed.

FIG. 3 is a diagram illustrating an example of the emphasis notification screen displayed by the screen display processing unit of the shoe purchase recommendation device according to the first embodiment. When the number of days until the purchase-recommended date becomes equal to or less than a predetermined number of days, the screen display processing unit 15 performs processing of changing the normal notification screen 200 to an emphasis notification screen 300 in which the purchase recommendation display area 202 is emphasized.

Specifically, the purchase recommendation display area 202 is enlarged after the measurement-recommended date display area 201, the message display area 203, and the previous measurement information display area 204 are displayed in a reduced manner or hidden. The enlarged purchase recommendation display area 202 occupies a larger proportion in the screen and contains a purchase-recommended product image 202A that has not been displayed on the normal notification screen 200. The purchase-recommended product image 202A is an image of a product to be purchased, and when the purchase recommendation processing unit 14 has determined a plurality of purchase-recommended products, the image of the purchase-recommended product having the highest recommendation priority is displayed at the center, while the image of the purchase recommendation target product having a recommendation priority other than the highest priority is displayed such that only a part of the image is accommodated within the purchase recommendation display area 202. For example, the purchase-recommended product image 202A for the purchase-recommended product having a recommendation priority other than the highest priority is displayed such that only the toe or only the heel is accommodated within the purchase recommendation display area 202. In the purchase recommendation display area 202, once the number of days until the purchase-recommended date becomes equal to or less than a predetermined number of days, the area of display is gradually enlarged as the number of days until the purchase-recommended date decreases.

When there is a plurality of purchase-recommended products, switch buttons 301 are displayed on the emphasis notification screen 300. When the switch button 301 is pressed by operating the input unit 22, the screen display processing unit 15 switches the purchase-recommended product image 202A displayed at the center of the purchase recommendation display area 202. Accordingly, by pressing the switch button 301 by operating the input unit 22, the user of the display input device 20 can cause the display input device 20 to display the entire image of the purchase-recommended product having a recommendation priority other than the highest priority at the center of the purchase recommendation display area 202. Note that, if the number of purchase-recommended products is too large, it is difficult for the user to decide which shoes to purchase, and thus the number of purchase-recommended products is preferably five or less. For example, in the shoe purchase recommendation device 10A according to the first embodiment, by taking three as the number of purchase-recommended products, at least a part of the purchase-recommended product image 202A of each purchase-recommended product is displayed in the purchase recommendation display area 202, such that it becomes easy for the user to decide which shoes to purchase.

In addition, an emphasis display cancel button 302 is displayed in the purchase recommendation display area 202 of the emphasis notification screen 300. When the emphasis display cancel button 302 is pressed by operating the input unit 22, the screen display processing unit 15 performs processing of returning the normal notification screen 200 from the emphasis notification screen 300.

Furthermore, a link 303 is displayed in the purchase recommendation display area 202 of the emphasis notification screen 300. By pressing the link 303 by operating the input unit 22, the user of the display input device 20 can purchase the shoes of which the purchase-recommended product image 202A is displayed at the center of the purchase recommendation display area 202, on an electronic commerce site.

To change the normal notification screen 200 to the emphasis notification screen 300, the purchase recommendation display area 202 may be superimposed on the measurement-recommended date display area 201, the message display area 203, and the previous measurement information display area 204 by sliding the purchase recommendation display area 202, or the purchase recommendation display area 202 may be transformed into a modal window and displayed by being superimposed on the measurement-recommended date display area 201, the message display area 203, and the previous measurement information display area 204. In addition, the change from the normal notification screen 200 to the emphasis notification screen 300 may be performed by a method other than the method exemplified here.

FIG. 4 is a flowchart illustrating a flow of action of the shoe purchase recommendation device according to the first embodiment. In step S11, the foot size change prediction unit 12 calculates the change prediction value of the foot size of the user on the basis of the user data 111 stored in the user data storage unit 11. In step S12, the purchase recommendation processing unit 14 determines the purchase-recommended date and the purchase-recommended product of shoes on the basis of the change prediction value calculated by the foot size change prediction unit 12 and the product information 131 stored in the product information storage unit 13.

In step S13, the screen display processing unit 15 performs processing of displaying the normal notification screen 200. In step S14, the screen display processing unit 15 verifies whether or not the number of days until the purchase-recommended date is equal to or less than a predetermined number of days. When the number of days until the purchase-recommended date is not equal to or less than the predetermined number of days, No is taken in step S14, and the process ends. When the number of days until the purchase-recommended date is equal to or less than the predetermined number of days, Yes is taken in step S14, and the process proceeds to step S15.

In step S15, the screen display processing unit 15 performs processing of changing the normal notification screen 200 to the emphasis notification screen 300.

The shoe purchase recommendation device 10A according to the first embodiment determines the purchase-recommended date and the purchase-recommended product on the basis of the change prediction value of the foot size of the user and the product information 131 including the shoe size 131A and displays the determined purchase-recommended date and purchase-recommended product on the normal notification screen 200. Accordingly, the shoe purchase recommendation device 10A according to the first embodiment is capable of notifying the user of the purchase-recommended date, which is an appropriate timing for purchasing shoes.

Moreover, when the number of days until the purchase-recommended date becomes equal to or less than a predetermined number of days, the shoe purchase recommendation device 10A according to the first embodiment performs processing of changing the normal notification screen 200 to the emphasis notification screen 300 in which the purchase recommendation display area 202 is displayed in an enlarged manner and thus can prompt the user not to miss the purchase-recommended date due to still overlooking the purchase-recommended date displayed in the purchase recommendation display area 202.

Second Embodiment

FIG. 5 is a diagram illustrating a configuration of a shoe purchase recommendation device according to a second embodiment of the present invention. A shoe purchase recommendation device 10B according to the second embodiment is different from the shoe purchase recommendation device 10A according to the first embodiment in that a designated genre 111D, which is a sports genre designated by a user, is included in user data 111, and an application genre 131C, which is a sports genre in which the shoes are used, is included in product information 131.

When there are shoes of which the application genre 131C matches the designated genre 111D among candidates for the purchase-recommended product selected on the basis of the change prediction value of the foot size, a purchase recommendation processing unit 14 determines the purchase-recommended product by prioritizing the shoes of which the application genre 131C matches the designated genre 111D.

FIG. 6 is a flowchart illustrating a flow of processing of the shoe purchase recommendation device according to the second embodiment to determine the purchase-recommended product. In step S21, the purchase recommendation processing unit 14 selects candidates for the shoes recommended to purchase on the basis of the change prediction value of the foot size. In step S22, the purchase recommendation processing unit 14 verifies whether or not there are shoes of which the application genre 131C matches the designated genre 111D among the selected candidates. When there are shoes of which the application genre 131C matches the designated genre 111D, Yes is taken in step S22, and the processing proceeds to step S23. When there are no shoes of which the application genre 131C matches the designated genre 111D, No is taken in step S22, and the processing proceeds to step S24.

In step S23, the purchase recommendation processing unit 14 determines the purchase-recommended product from among the candidates selected in step S21, by prioritizing the shoes of which the application genre 131C matches the designated genre 111D.

In step S24, the purchase recommendation processing unit 14 determines the purchase-recommended product from among the candidates selected in step S21, by prioritizing shoes having a high degree of fitting in the foot size. Note that it is assumed that the shoes of which a median value of the foot size fitting range is closer to the foot size prediction value has a higher degree of fitting in the foot size.

The shoe purchase recommendation device 10B according to the second embodiment can determine the purchase-recommended product by prioritizing shoes suitable for the genre designated in advance by the user, from among the shoes fitting to the change prediction value of the foot size of the user, and thus can recommend the purchase of the shoes suited to the preference of the user.

Note that approximate genres may be set in advance for sports genres that can be designated as the designated genre 111D such that, when there are no shoes of which the application genre 131C matches the designated genre 111D, a product to be purchased is determined by prioritizing the shoes for the approximate genre. For example, competition groups such as an indoor court category including basketball, volleyball, and badminton, an outdoor limited contact category including soccer, rugby, and baseball, and an outdoor non-contact category including tennis, lacrosse, and track and field events may be set such that, when there are no shoes of which the application genre 131C matches the designated genre 111D among the candidates for the purchase-recommended product, the purchase recommendation processing unit 14 determines the purchase-recommended product by prioritizing the shoes for a competition belonging to the competition group including the designated genre 111D. Note that the case where “there are no shoes of which the application genre matches the designated genre” includes both of a case where the commodity itself does not exist and a case where the commodity exists but there is no stock.

Third Embodiment

FIG. 7 is a diagram illustrating a configuration of a shoe purchase recommendation device according to a third embodiment of the present invention. A shoe purchase recommendation device 10C according to the third embodiment is different from the shoe purchase recommendation device 10A according to the first embodiment in that a designated color 111E, which is a color designated by a user, is included in user data 111, and a shoe color 131D, which is information on the color of the shoes, is included in product information 131. The shoe color 131D is not limited to the color of a region occupying a large proportion on the outer surface of the shoe and may be a color of a logo mark provided on the outer surface of the shoe, or may be a color of a conspicuous part although occupying a small proportion on the outer surface of the shoe.

When there are shoes of which the shoe color 131D matches the designated color 111E among the candidates for the purchase-recommended product selected on the basis of the change prediction value of the foot size, a purchase recommendation processing unit 14 determines the purchase-recommended product by prioritizing the shoes of which the shoe color 131D matches the designated color 111E.

In step S51, the purchase recommendation processing unit 14 selects candidates for the shoes recommended to purchase on the basis of the change prediction value of the foot size. In step S52, the purchase recommendation processing unit 14 verifies whether or not there are shoes of which the desired sporting ability value 131E is equal to or less than the sporting ability measurement value 111F among the selected candidates. When there are shoes of which the desired sporting ability value 131E is equal to or less than the sporting ability measurement value 111F, Yes is taken in step S52, and the processing proceeds to step S53. When there are no shoes of which the desired sporting ability value 131E is equal to or less than the sporting ability measurement value 111F, No is taken in step S52, and the processing proceeds to step S54.

In step S53, the purchase recommendation processing unit 14 determines the purchase-recommended product from among the candidates selected in step S51, by prioritizing the shoes of which the desired sporting ability value 131E is equal to or less than the sporting ability measurement value 111F.

In step S54, the purchase recommendation processing unit 14 determines the purchase-recommended product from among the candidates selected in step S51, by prioritizing shoes having a high degree of fitting in the foot size. Note that it is assumed that the shoes of which a median value of the foot size fitting range is closer to the foot size prediction value has a higher degree of fitting in the foot size.

In particular, in sports shoes, a plurality of models is sometimes provided by performance of the wearer. In general, a model for beginners has specifications that give more importance on ease of handling than potential, whereas a model for advanced-level persons has specifications that give more importance on potential than ease of handling. Accordingly, if a person with low sporting ability wears a model for advanced-level persons, the original potential of the shoes will not be allowed to be sufficiently drawn out, and as a result, the wearer will not be able to sufficiently exhibit the own performance of the wearer. In addition, if a person with high sporting ability wears a model for beginners, the wearer will not be able to sufficiently exhibit the own performance of the wearer because the wearer is restricted by the potential of the shoes. By determining shoes recommended to purchase on the basis of the sporting ability of the user, the shoe purchase recommendation device 10E according to the fifth embodiment can recommend the purchase of the shoes that allow the user to easily exhibit performance.

Sixth Embodiment

FIG. 13 is a diagram illustrating a configuration of a shoe purchase recommendation device according to a sixth embodiment of the present invention. A shoe purchase recommendation device 10F according to the sixth embodiment is different from the shoe purchase recommendation device 10A according to the first embodiment in including a purchase recommendation interval determination unit 16 that determines a purchase recommendation interval on the basis of an age 111A of the user.

When the purchase-recommended date based on the change prediction value and product information 131 has not been set until the purchase recommendation interval has elapsed from the previous purchase-recommended date, a purchase recommendation processing unit 14 sets the day on which the purchase recommendation interval elapses, as the purchase-recommended date.

Since, for example, the sole of the shoe is worn out as the shoe is used, it is preferable even for a user at an age with little change in the foot size to periodically purchase shoes for replacement. Even when the purchase-recommended date based on the change prediction value and the product information 131 has not been set until the purchase recommendation interval determined on the basis of the age 111A of the user has elapsed from the previous purchase-recommended date, the shoe purchase recommendation device 10F according to the sixth embodiment sets the day on which the purchase recommendation interval elapses, as the purchase-recommended date, and thus can recommend the purchase of shoes at an appropriate timing even for the user at an age with little change in the foot size. Meanwhile, when a child whose foot size changes in a short period of time, particularly a child in a growth period, is the user, the purchase of shoes at an appropriate timing can be recommended because the purchase-recommended date is set on the basis of the change prediction value of the foot size and the product information 131.
