Description

Technical Field

[0001] This invention relates to displaying recommendation information for wearable items on a computer system of a terminal device, etc. Background Technology

[0002] Previously, techniques have been proposed for providing information about clothing that corresponds to changes in the wearer's body shape. For example, Patent Document 1 discloses a technique for determining information to purchase children's clothing. Specifically, in the technique of Patent Document 1, permissible sizes for children's clothing are pre-stored, and based on the permissible sizes and the growth pattern of the wearer (child user), the technique predicts the date when the wearer will become unable to wear the clothing. Therefore, the user can consider purchasing the clothing after knowing its wearability period.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2007-265077 Summary of the Invention

[0006] The technical problem that the invention aims to solve

[0007] However, the technology in Patent Document 1 prompts the user by considering the period until the child user becomes unable to wear the clothing as the wearable period, rather than by prompting the user based on whether the clothing is comfortable to wear. Furthermore, while clothing has been described in relation to wearable items, the same technical problem exists for other wearable items such as shoes or hats.

[0008] The technical problem to be solved by the present invention is to provide a technology that can indicate the size of an item that a user can comfortably wear.

[0009] Technical solutions for solving technical problems

[0010] The first invention for solving the above-mentioned technical problem is a computer system for controlling the provision of recommended information about an item to a user. The computer system includes: an estimation unit that estimates a recommended size of the item that meets predetermined comfort conditions over a predetermined comfort period consisting of multiple days, based on size information about the size of the item, body size information about body dimensions related to the part of the user wearing the item, and growth change information about the growth changes of the wearing part; and a control unit that controls the provision of the recommended size estimated by the estimation unit as the recommended information.

[0011] Furthermore, the second invention is an online shopping system comprising a server and a terminal. The online shopping system controls the display of recommended information about items to a user. The system includes: a functional unit that performs information processing related to the provision of online shopping services; an estimation unit that estimates a recommended size of the item that meets predetermined comfort conditions over a predetermined comfort period consisting of multiple days, based on size information about the item's dimensions, body size information about the body dimensions of the user wearing the item, and growth change information about the growth changes of the wearing body; and a control unit that controls the display of the recommended size estimated by the estimation unit as the recommended information.

[0012] Furthermore, the third invention is a computer system that controls the display of recommended information for wearable items on a terminal device. The system comprises: an acquisition unit that acquires measurement information about the wearing parts of the item worn by a target user; an estimation unit that, if the target user is wearing the item, estimates a first recommended size based on the measurement information to satisfy predetermined comfort conditions during a first comfort period; and a recommendation display control unit that performs recommendation display control to display a first recommended size indicating the first recommended size on the terminal device.

[0035] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It is important to note that the invention is not intended to be limited by the embodiments described below, and the forms in which the invention can be applied are not limited to the following embodiments. Furthermore, in the accompanying drawings, the same reference numerals are used to denote the same parts.

[0036] [Overall Composition]

[0037] Figure 1This is a diagram illustrating an example of the overall configuration of the online shopping system 1000 in this embodiment. (See diagram for details.) Figure 1 As shown, the online shopping system 1000 includes a server system 1100 and a terminal device 1500, which are connected to each other via a network 9 to enable data communication. The online shopping system 1000 provides an online shopping service for selling wearable items. Hereinafter, shoes, as a type of footwear, will be used as an example, but the same principle applies when selling footwear including boots (thigh boots), and when selling other items such as clothing or hats.

[0038] Network 9 refers to a communication path capable of data communication. That is, Network 9 means not only LANs (Local Area Networks) based on dedicated lines (dedicated cables) and Ethernet (registered trademark) for direct connection, but also telephone communication networks or wired networks, the Internet, and other communication networks. Furthermore, regarding the communication method, wired or wireless is not distinguished.

[0039] Server system 1100 is a computer system comprising: a main unit 1101, a keyboard 1106, a touch panel 1108, and a storage device 1140. The main unit 1101 is a control board 1150 that integrates various microprocessors such as a CPU (Central Processing Unit) 1151 or GPU (Graphics Processing Unit), DSP (Digital Signal Processor), various IC memories such as VRAM, RAM, and ROM 1152, and communication devices 1153. Part or all of the control board 1150 can also be implemented using an ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), or SoC (System on a Chip).

[0040] The server system 1100 processes data and performs calculations based on predetermined programs using a CPU 1151 and other components, thereby enabling: user management functions such as user registration and account linking for data management; and online shopping functions related to the provision of online shopping services. This includes providing programs for the terminal device 1500 used to implement these functions, or providing various data required for executing those programs. Registered users access the server system 1100 using their own terminal device 1500 and log in using their issued registered user ID to enjoy online shopping.

[0041] Among them, Figure 1 The text only describes one terminal device 1500, but in actual system applications, multiple terminal devices 1500 can access the server system 1100 simultaneously.

[0042] Furthermore, although the server system 1100 is described as a single server device, it can also be configured as multiple devices. For example, the server system 1100 could be configured to house multiple blade servers that perform various functions and are interconnected via an internal bus for data communication. Moreover, the location of the hardware constituting the server system 1100 is not important. It could also be configured so that multiple independent servers located in remote locations communicate via a network 9, thereby functioning as a whole as the server system 1100.

[0043] Terminal device 1500 is a computer system responsible for human-computer interface functions. It can be connected to network 9 through communication base stations, etc., and can communicate with server system 1100 for data. Figure 2 The terminal device 1500 shown is classified as a smartphone, but if it is a computer, it could also be a wearable computer such as a smartwatch, a portable gaming device, a tablet computer, a personal computer, etc. When multiple electronic devices, such as a smartphone and a smartwatch that communicates with the smartphone, are organically combined to perform a single function, these multiple electronic devices can be regarded as a single terminal device 1500.

[0044] Figure 2 This is a diagram illustrating an example of the device configuration of a smartphone, which is one example of a terminal device 1500. (See diagram below.) Figure 2 As shown, the terminal device 1500 includes: directional input keys 1502, a Home button 1504, a touch panel 1506 that functions as both an image display element and a touch position input element, a built-in battery 1509, a speaker 1510, a microphone 1512, a camera 1520, a control board 1550, and a memory card reader 1542 that can read and write data to a memory card 1540, which is a computer-readable storage medium. Additionally, it includes a power button, volume control buttons, etc. (not shown).

[0045] The control board 1550 is equipped with various microprocessors such as CPU 1551, GPU, and DSP; various IC memories such as VRAM, RAM, and ROM 1552; a wireless communication module 1553 for wireless communication with mobile phone base stations or wireless communication base stations connected to network 9; and interface circuit 1557. The interface circuit 1557 includes: a circuit for receiving signals from the directional input key 1502 or the Home key 1504; a driving circuit for the touch panel 1506; an output amplification circuit for outputting sound signals to the speaker 1510; a sound signal generation circuit for generating sound signals collected by the microphone 1512; a circuit for inputting image signals captured by the camera 1520; and a signal input / output circuit for the memory card reader 1542.

[0046] The various elements mounted on these control boards 1550 are electrically connected via bus circuits or the like, and are connected in a manner that allows for data reading and writing or signal transmission and reception. The control board 1550 may also be composed of an ASIC, FPGA, or SoC, or may be entirely composed of such components. Next, the control board 1550 stores programs or various data used to implement the functions of the terminal device in the IC memory 1552.

[0047] In this embodiment, the terminal device 1500 is configured to download programs or various setting data from the server system 1100, but it can also be configured to read from a storage medium such as a separately acquired memory card 1540.

[0048] [detailed]

[0049] 1. Regarding user management functions

[0050] Server system 1100 is designed to implement user management functions, including processing related to user registration (user registration processing) and managing data of registered users who have gone through the registration process, or data of users associated with those registered users (data management processing).

[0051] In this embodiment, such as Figure 3As shown, the user IDs of one or more wearing users can be associated with the registered user IDs of registered users. Registered users log in with their registered user IDs and make online purchases of various items such as short shoes. On the other hand, wearing users are those wearing the short shoes purchased by the registered user. Wearing users can be the registered user, a family member, or a friend. In this embodiment, for ease of explanation, an example is shown where the wearing user is the registered user's child. The registered user registers the child as a wearing user, thereby issuing a wearing user ID to that wearing user. User data (see reference) is stored in each corresponding wearing user ID for the user data acquired during the data acquisition process described later. Figure 19 The user data (520) includes: attribute information such as the wearer's age or gender, measurement information of the wearer at the wearing part (foot) of the item (short shoes in this embodiment), and comfort variation information generated using the wearer's attribute information or measurement information. As described later, the comfort variation information is generated for each wearer and for each item (short shoes sold through an online shopping service in this embodiment).

[0052] 2. Regarding online shopping functionality

[0053] Server system 1100 performs data acquisition processing to obtain user data related to target users in order to realize online shopping functions. Furthermore, if a registered user is logged in, server system 1100 responds to a request for product retrieval from terminal device 1500 and controls the display of product information for matching items on terminal device 1500. Next, before displaying the product information, server system 1100 performs target user setting processing. Afterwards, server system 1100 performs: estimation processing, which estimates the recommended size for each item in the product information, based on the target user; recommendation display control processing, which displays a recommendation indicating the recommended size on terminal device 1500; and remeasurement request display control processing, which prompts terminal device 1500 to remeasure after recommendation display control.

[0054] 2-1. Regarding data acquisition and processing

[0055] In the data acquisition and processing, the server system 1100 acquires user data by using the clothing user specified by the registered user in the terminal device 1500 as the target user. This operation is performed when a new clothing user is registered, or when measurement information is requested for any clothing user, and the clothing user is specified as the target user.

[0056] At this point, the server system 1100 first obtains the attribute information of the target user. This information is obtained based on input operations such as age or gender processed in the terminal device 1500.

[0057] Next, the server system 1100 acquires the measurement information of the target user. This measurement information includes shape data of the wearing part (foot in this embodiment) and data on the growth and changes in the wearing part. For example, this information can be acquired through measurements using a means that can measure foot size. As an example, first, a predetermined mat with many dots (markers) is prepared for measurement, and the terminal device 1500 photographs the target user's foot placed on the mat from multiple directions. Then, based on the photographed data and the dots (markers) on the mat, a 3D model of the foot is created, and various data (shape data) related to the shape of the target user's foot, such as the overall shape of the foot, the shape of the instep, the size of the foot, the width of the foot, and whether it is flatfoot, are measured. Alternatively, other methods can be used if the same data can be acquired. For example, the terminal device 1500 can photograph the target user's foot placed on a flat surface from multiple directions, and the same data can be measured using photogrammetry processing based on the photographed data. The measurement processing can be performed by the terminal device 1500, or by the server system 1100 acquiring the captured data and performing the processing. This results in a difference in the configuration where the measurement method is provided by either the terminal device 1500 or the server system 1100. Alternatively, the same data can be obtained by manually inputting numerical values ​​such as the length of the user's foot into the terminal device 1500. Ultimately, the server system 1100 acquires the measurement data (measurement result). Then, based on the measurement result or the user's attribute information, the server system 1100 predicts the growth changes of the user's foot. For example, it predicts the foot size at each age (e.g., in months) after the measurement time, acquiring the predictive change in size at each age as growth change data. The server system 1100 acquires the obtained shape data and growth change data as measurement information for the user.

[0058] This can be structured as a growth change data system using the average foot size of children of the same sex (the average foot size at each age). Alternatively, growth change data (average foot size at each age) for children with fast growth rates and those with slow growth rates can be prepared in advance, using the growth rate data (average) of the corresponding target user as the growth change data. Furthermore, it can be structured as a system that includes exemplified averages, using measurement results (i.e., measured values) obtained through measurement methods to predict growth changes. Alternatively, growth changes can be predicted based on information entered by registered users about the target user (e.g., attributes such as age or gender, height, weight, etc.) or images of the target user's body (here, feet) taken (e.g., images of feet taken from various angles).

[0059] If measurement information has been obtained, the server system 1100 generates comfort variation information for each pre-defined item (e.g., short shoes sold in an online shopping service), based on the item information, the attribute information, and the measurement information of the target user, indicating the change in comfort level of the target user over a corresponding period of time while wearing the item. The attribute information and measurement information of the target user are not limited to the composition of both users; they can also be the composition of either user.

[0060] Item information includes the item's name, category, dimensions, material or size, weight, and other specifications, as well as information based on the purchaser's assessment of the item. When generating comfort variation information using this assessment information, for example, information from assessments conducted by registered users who have registered as wearers with attribute or measurement information similar to the target user can be extracted and used to generate comfort variation information. Specifically, when generating the comfort chart described later, this assessment information can be used to adjust the shape of the parabola, making it steeper or flatter.

[0061] Figure 4 , Figure 5 , Figure 6 This diagram illustrates an example of comfort variation information generated for each of the items (short shoes) I1, I2, and I3, with user U1 as the target user. In this embodiment, the generation of comfort variation information is performed from the measurement time (i.e., the time before the previous measurement was performed for user U1) to a predetermined target period (the measurement time before the previous measurement was performed for user U1) related to the measurement information of the target user (user U1). Figure 4 In the example, comfort levels at various time points between 14 months and 2020 (e.g., comfort variations represented by values ​​from "0" (very poor) to "100" (very good)) are shown. Figure 4 In the process, for the generated comfort level change information, the portion with a comfort level of 50 or higher is extracted and represented.

[0062] When generating comfort variation information for a single item, for example, server system 1100 expands the data according to the size of the item being generated, and performs the following processing for each size: First, based on the measurement information of the target user (in this case, user U1 wearing the item), a time point considered most suitable in terms of size is set (estimated optimal time point). Next, the comfort level of the estimated optimal time point is set to 100, and a parabolic graph with the estimated optimal time point as its vertex is generated as a graph of comfort for that size. At this point, using item information, the shape of the parabola in the generated graph is adjusted (either to form a gently sloping parabola or a steeply sloping parabola). This process is repeated for each size, generating a comfort graph for each size, thereby obtaining comfort variation information.

[0063] For example, in Figure 4 The examples show examples of generating charts G1-1 (for user U1 wearing 12cm), G1-2 (for user U1 wearing 12.5cm), G1-3 (for user U1 wearing 13cm), and G1-4 (for user U1 wearing 13.5cm) regarding comfort variation information related to item I2. Similarly, in Figure 5 The examples show examples of generating charts G2-1 (for user U1 wearing 12cm), G2-2 (for user U1 wearing 12.5cm), G2-3 (for user U1 wearing 13cm), and G2-4 (for user U1 wearing 13.5cm) regarding comfort variation information related to item I2. Figure 6 The examples show charts G3-1 and G3-2, which generate charts showing the comfort level of user U1 when wearing 12cm and 13cm respectively, in terms of information on the changes in comfort level of item I3.

[0064] Here, when comparing Figure 4 Item I1 and Figure 5 When considering item I2, even if it is the same size, if item I2 is designed to be smaller (e.g., if a non-stretchable material is used as the material for item I2), the period during which item I2 can be comfortably worn is shorter compared to item I1. Therefore, when the server system 1100 generates a comfort chart for each size, it adjusts the shape of the parabola to be steeper for items designed to be tighter (e.g., item I2).

[0065] Conversely, when comparing items to each other, even if they are the same size, if one item is designed to be larger (e.g., if one item is made of a stretchable material), it can be worn comfortably for a longer period compared to the other item. Therefore, when the server system 1100 generates a comfort chart for each size, it adjusts the shape of the parabola to be flatter for the larger item.

[0066] Furthermore, when comparing items, there may be cases where the size scale of one item is larger than that of the other item. For example, Figure 6 The dimensions of item I3 are marked in 1cm increments. In contrast, Figure 4 Item I1 or Figure 5 The size of item I2 is marked with a 0.5cm scale. Therefore, when the server system 1100 generates a chart of comfort for each size, items with larger scales are adjusted in a way that makes the parabolic shape flatter compared to smaller items.

[0067] The measurement information or comfort change information is acquired and updated to the latest information whenever relevant measurement information is taken for the target user.

[0068] Furthermore, comfort variation information can be incorporated into the composition generated based on the preferences of the target user regarding the wearing of the item (e.g., preferring a larger or narrower fit). Specifically, for example, information regarding the feeling of wearing shoes for children with similar preferences to the target user can be extracted from the assessment information included in the item information and used in the generation of comfort variation information. Specifically, when generating a comfort chart for each size, this assessment information can be used to adjust the shape of the parabola, making it steeper or gentler.

[0069] 2-2. User setting processing for purchase targets

[0070] In the process of setting up the target user for online shopping, the server system 1100 sets up the target user for online shopping based on the operation input in the terminal device 1500. Registered users select the clothing user (child) associated with them. The server system 1100 then sets the selected clothing user as the target user for online shopping.

[0071] 2-3. Estimation Processing

[0072] In this embodiment, the server system 1100 uses the purchase target user set in the purchase target user setting process as the target user, and performs the estimation processing, the subsequent recommendation display control processing, and the remeasurement request display control processing. The following lists relevant... Figures 4-6 The following example illustrates the processing when the user U1, who is wearing the garment, is the target user (when the parent's registered user selects the user U1 as the target user for purchase).

[0073] In the estimation process, the server system 1100 estimates the recommended size of an item for the target user (e.g., user U1) to wear based on the target user's measurement information. In this embodiment, for each item (hereinafter also referred to as the "estimated target item") displayed on the terminal device 1500 in response to a registered user's product search, a first recommended size is estimated to meet a predetermined comfort condition during a first comfort period, and a second recommended size is estimated to meet the comfort condition during a second comfort period that begins later than the first comfort period. These are used as the recommended size for the target user to wear the estimated target item. Specifically, the server system 1100 estimates the first and second recommended sizes using comfort variation information generated for the estimated target item based on measurement information, etc. At this time, the comfort condition can be set, for example, "in the comfort variation information of the estimated target item for the target user, the comfort level is 80 or higher."

[0074] For example, if the object to be estimated is item I1, use Figure 4 The comfort variation information shown estimates the first and second recommended sizes for the user wearing the U1. As described above, the comfort variation information is obtained from information about the target user ( Figure 4 The value generated when measuring user U1 is provided represents the comfort level at various points in time from the previous measurement time (the time of the previous measurement) to a predetermined period. Therefore, in the estimation process, the current time is used as the baseline time, and comfort changes compared to that baseline time are referenced. For example, if a search for product information based on a registered user is performed immediately after a measurement is taken of the target user, Figure 4 The time point T11, where the elapsed period is 0 (the previous measurement timing), becomes the reference timing. At this time, the reference... Figure 4The charts G1-1 to G1-4 show the comfort level variation information. First, if we look at chart G1-1, the comfort level is 80 or higher during the period from the baseline time T11 to 4 months later. Therefore, the server system 1100 sets this period as the first comfort period for the user U1, and estimates the first recommended size of item I1 during this first comfort period as the size corresponding to chart G1-1 (12cm). Furthermore, if we look at chart G1-2, the comfort level is 80 or higher during the period from 3.5 months to 7.5 months after the baseline time T11. Therefore, the server system 1100 sets this period as the second comfort period for the user U1, and estimates the second recommended size of item I1 during the second comfort period as the size corresponding to chart G1-2 (12.5cm). The same estimation is performed for charts G1-3 and G1-4.

[0075] On the other hand, for example, if a registered user retrieves product information at a time point T13 five months after the previous measurement, that time point T13 five months later is used as the baseline time, and reference is made... Figure 4 The comfort variation information is presented in charts G1-2 to G1-4, which are the portion following the baseline time T13. First, looking at chart G1-2, the comfort level is 80 or higher during the period from baseline time T13 to 2.5 months later (7.5 months later from the previous measurement time). Therefore, server system 1100 sets this period as the first comfort period for the user U1, and estimates the first recommended size of item I1 during this first comfort period as the size corresponding to chart G1-2 (12.5cm). Furthermore, looking at chart G1-3, the comfort level is 80 or higher during the period from 2 months later (7 months later from the previous measurement time) to 6 months later (11 months later from the previous measurement time) after baseline time T13. Therefore, server system 1100 sets this period as the second comfort period for the user U1, and estimates the second recommended size of item I1 during the second comfort period as the size corresponding to chart G1-3 (13cm).

[0076] Similarly, if the estimated object is item I2, use Figure 5 The comfort variation information shown estimates the first and second recommended sizes for the user wearing U1. For example, using the time point T2 of the previous measurement as the reference time, referencing... Figure 5The charts G2-1 to G2-4 show the comfort level variation information. Looking at chart G2-1, the comfort level is 80 or higher during the period from 1 month to 4.25 months after the baseline time T2. Therefore, this period is defined as the first comfort period for wearer U1, and the first recommended size of item I2 during this first comfort period is estimated as the size corresponding to chart G2-1. This example illustrates that item I2, with its size unfolded from 12cm, does not have a size that wearer U1 can comfortably wear at the baseline time T2. The same estimation is performed for charts G2-2 to G2-4.

[0077] In addition, if the estimated object is item I3, then use Figure 6 The comfort variation information shown estimates the first and second recommended sizes for the user wearing the U1. For example, if the time point T3 of the previous measurement is set as the reference time, refer to... Figure 6 The charts G3-1 and G3-2 show the changes in comfort level. Looking at chart G3-1, the comfort level is above 80 during the period from the baseline time T3 to 8 months later. Therefore, this period is defined as the first comfort period for the wearer U1, and the first recommended size for item I3 during this first comfort period is estimated as the size corresponding to chart G3-1. The same estimation is performed for chart G3-2.

[0078] This can also include a structure where a comfort threshold is set for each registered user. For example, if a registered user wants to purchase an item that can be worn for as long as possible even if there is a slight difference between the target user's foot size and the item size, the comfort threshold might be set to 70. For example, if the previous measurement time point T3 is set as the reference time when the estimated target item is item I3, and the user observes... Figure 6 According to Chart G3-1, the comfort level is above 70 during the period from the baseline time T3 to 8.5 months later. Therefore, server system 1100 sets this period as the first comfort period for the wearer U1, and sets the first recommended size of item I3 during this first comfort period as the size corresponding to Chart G3-1.

[0079] Alternatively, for example, if the ease of movement for registered users while wearing the garment is important, the comfort threshold can be set relatively high, such as 90 or 95. For instance, if the estimated object is item I1, and the previous measurement timing point T11 is set as the reference timing, if the viewer... Figure 4Chart G1-1 shows a comfort level of 95 or higher during the period from 1 month to 3 months after the baseline time T11. Therefore, server system 1100 sets this period as the first comfort period for user U1 and sets the first recommended size of item I1 during this first comfort period as the size (12cm) corresponding to chart G1-1. Furthermore, if the estimated object item is item I2 and the previous measurement time point T2 is set as the baseline time, if viewing... Figure 5 According to Chart G2-1, the comfort level is above 90 during the period from 1.75 months to 3.75 months after the baseline time T2. Therefore, server system 1100 sets this period as the first comfort period for user U1, and sets the first recommended size of item I2 during this first comfort period as the size corresponding to Chart G2-1.

[0080] Prioritizing durability and ease of use even with frequent exchanges is crucial, and this can be achieved, for example, by processing pre-registration based on user questionnaire input.

[0081] Furthermore, it is also possible to set the comfort threshold, which is a condition for comfort, according to the category of the item. For example, if the category of item I1 is "sports shoes", the comfort threshold is set to 95, emphasizing the ease of movement when wearing them.

[0082] Furthermore, it can be configured such that the comfort threshold, which serves as a comfort condition, is set based on the items the target user has previously worn. For example, if an item is exchanged (increased in size) when the comfort level is below 90, the comfort threshold can be set to 90. This can be based on the purchase history data of registered users 531 (see [reference]). Figure 19 This is achieved by obtaining the date and time when the item was bought or exchanged.

[0083] Furthermore, the setting of the comfort threshold (i.e., the setting of comfort conditions) can also be configured to be based on the input operation based on the threshold of the registered user.

[0084] 2-4. Recommended display control processing

[0085] In the recommended display control process, the server system 1100 performs a first recommended display, which together indicates a first recommended size estimated for the target user in the estimation process, and a second recommended display indicating a second recommended size is displayed in the recommended display control of the terminal device 1500.

[0086] Subsequently, the server system 1100 executes recommendation display control processing, setting the purchase target user as the target user in the purchase target user setting processing, and performs recommendation display control to display the first recommendation display and the second recommendation display on the terminal device 1500. In this embodiment, the server system 1100 performs recommendation display control based on control to establish an association with the first recommendation display to display the first comfort period display, and control to establish an association with the second recommendation display to display the second comfort period display.

[0087] Figure 7 This diagram illustrates an example of a recommended display screen displayed on the terminal device 1500 according to recommended display control. For example... Figure 7 As shown, in the recommended display screen W4, according to the recommended display control performed by the server system 1100, for each item that is the estimation object in the estimation process, a first recommended size and a first comfort period, and a second recommended size and a second comfort period are displayed. Figure 7 The image shows an example of a display for an item I4, showing the target user (...). Figure 7 The first recommended size D41 of item I4 is estimated when the wearer (U1) wears item I4, and the first comfort period D43 is when item I4 can be comfortably worn with the first recommended size. In addition, along with the display of the first recommended size and the first comfort period, the second recommended size D45 of item I4 is estimated when the target user (wearer U1) wears item I4, and the second comfort period D47 is when item I4 can be comfortably worn with the second recommended size.

[0088] If the recommended dimensions are estimated for a comfort period that is later than the start date of the second comfort period, a configuration that is also shown for those periods can be formed. For example, if it is... Figure 4 For example, in addition to displaying the first recommended size and first comfort period according to Chart G1-1 and the second recommended size and second comfort period according to Chart G1-2, the recommended size and comfort period according to Chart G1-3 or the recommended size and comfort period according to Chart G1-4 can also be displayed.

[0089] Furthermore, it can also be configured to be an item of the first recommended size, thus displaying the current level of comfort. For example, if it is... Figure 4 For example, if the reference timing is T11, the first recommended size will be displayed as a comfort level of "80". If... Figure 4 When the elapsed period is 2 minutes and the time point T15 is used as the reference timing, the comfort level is displayed as "100" for the first recommended size.

[0090] Furthermore, it can be configured to display only the recommended dimensions (first recommended dimensions and second recommended dimensions, etc.), without displaying the comfort period (first comfort period and second comfort period, etc.). Alternatively, it can be configured to display only the first recommended dimensions (first recommended dimensions and first comfort period) without displaying the second recommended dimensions (second recommended dimensions and second comfort period). Furthermore, it can be configured to display both the first recommended dimensions (first recommended dimensions and first comfort period) and the second recommended dimensions, but not the second comfort period.

[0091] 2-5. Remeasurement Request Display Control Processing

[0092] In the remeasurement request display control process, for the user subject to recommended display control according to the recommended display control process, the measurement timing of the measurement information for that user (the previous measurement timing for the user during the previous measurement) is determined. Then, the server system 1100 performs the following control: if the number of days elapsed from the determined measurement timing meets a first remeasurement request interval condition, a remeasurement request display urging the terminal device 1500 to perform the recommended display control is added. Furthermore, the server system 1100 performs the following emphasis display control: if the number of days elapsed from the determined measurement timing meets a second remeasurement request interval condition that is a later date than the first remeasurement request interval condition, the remeasurement request display is emphasized.

[0093] If the measurement information of the target users has not been measured for a long period of time, and the measurement information becomes outdated, the comfort chart shown in the comfort change information will become inconsistent with the actual foot size of the target users, increasing concerns about the reduced accuracy of the first or second recommended size estimated based on the comfort change information.

[0094] Therefore, in this embodiment, the first remeasurement request interval condition is set to, for example, "more than 3 months". Then, if 3 months have passed since the last measurement for the target user, the server system 1100 controls the display of the remeasurement request body. Furthermore, the second remeasurement request interval condition is set to, for example, "more than 6 months". Then, if 6 months have passed since the last measurement for the target user, the server system 1100 emphasizes the remeasurement request body. Examples of the display and emphasis of the remeasurement request body are shown below.

[0095] (Example 1)

[0096] Figure 8 This is a diagram illustrating an example of the display control for the remeasurement request display body W5 in Example 1. Furthermore, Figure 9This diagram illustrates an example of the emphasis display control for the remeasurement request display body W5. In this example, if more than 3 months have passed since the last measurement and the first remeasurement request interval condition is met, the server system 1100 will... Figure 7 The recommended display screen W4 is shown, and the additional display screen W5 shows the remeasurement request. Figure 8 ).exist Figure 8 The image shown is located at the top of the recommended display screen W4, in conjunction with the content displayed on the recommended display screen W4 (see reference). Figure 7 This is an example of displaying the remeasurement request display body W5 in a non-overlapping manner. The display position of the remeasurement request display body W5 is not limited to the top of the screen.

[0097] The remeasurement request display W5 shows a remeasurement button B along with a message urging remeasurement, serving as an execution instruction for reacquiring measurement information. When a registered user of the terminal device 1500 proceeds to the reacquisition stage, they select the remeasurement button B and input necessary operations for the user's measurement.

[0098] Therefore, if a target user has not been measured for more than 3 months, a remeasurement request display W5 can be added to the recommended display screen W4, which displays the recommended size specifically for the target user, and the target user can be urged to take the measurement.

[0099] Furthermore, if more than six months have passed since the last measurement and the second remeasurement request interval condition is met, the server system 1100 will emphasize the remeasurement request display body W5. In this example, the server system 1100 will increase the display size of the remeasurement request display body W5 as an emphasis display control. For example, if the server system 1100... Figure 9 As shown, a remeasurement request is made to the display unit W5 to maximize the size of the entire screen. If from... Figure 9 When scrolling downwards as shown, the recommended display screen W4 is displayed.

[0100] Therefore, if a target user has not been remeasured for more than 6 months, the remeasurement request display W5 is displayed more prominently on the terminal device 1500, and the registered user is strongly urged to remeasure.

[0101] This can be configured to perform emphasis display control based on the remeasurement request display body that overlaps with the front side of the recommended display screen W4. Figure 10 This diagram illustrates an example of the display control of the W51 display body for a remeasurement request at this time. As shown in this example, it is also possible to... Figure 7 On the recommended display screen W4 shown, the remeasurement request display body W51 is displayed as a pop-up window.

[0102] (Example 2)

[0103] Figure 11 This diagram illustrates an example of the emphasis display control for the remeasurement request display W6 in Example 2. In this example, if the number of days elapsed since the last measurement timing meets the second remeasurement request interval condition, the server system 1100 controls the display content (in this case, the recommended display screen) that is further inward than the remeasurement request display W6 to be non-displayed. Figure 11 The diagram shows an example where the recommended display screen is replaced by the remeasurement request display W6, which is displayed on the entire screen (i.e., the screen that transitions from the original screen to the remeasurement request display W6), thus making the recommended display screen invisible. When a registered user selects the remeasurement button B and the measurement is completed for that user, the recommended display screen can be viewed.

[0104] This example illustrates how the display content on the inner side of the remeasurement request display body W6 can be made non-displayable, but it can also be configured to control the display for visual confirmation purposes. For example, as in Example 1, if from... Figure 9 In the scenario where the recommended display screen W4 is displayed when scrolling downwards, it is also possible to control the display of the recommended display screen W4 to be blurred or to be displayed in a mixed color with the background color.

[0105] (Example 3)

[0106] Figure 12 This is a diagram illustrating an example of the display control for the remeasurement request display body W7 in Example 3. Furthermore, Figure 13 This is a diagram illustrating an example of the emphasis display control of the remeasurement request display body W7 in Example 3. In this example, if the number of days since the last measurement timing meets the first remeasurement request interval condition, the server system 1100 displays the remeasurement request display body W7 at its maximum size. Figure 12 (a)

[0107] Next, if a scrolling operation is performed on the terminal device 1500, the server system 1100, as follows: Figure 12 As shown in (b), the remeasurement request display W7 is configured as a floating window and displayed above the recommended display screen W4. In this example, after one scrolling operation, the remeasurement request display W7 is always displayed at the top of the screen, urging the registered user to perform a remeasurement. However, the display position of the remeasurement request display W7 is not limited to the top of the screen.

[0108] Furthermore, if the number of days since the last measurement timing meets the second remeasurement request interval condition, the server system 1100 will emphasize the remeasurement request display body W7. In this example, if... Figure 13 As shown, to make with Figure 12 (a) The same principle applies, but the maximum size is requested for remeasurement and display on the W7 display. However, server system 1100 and Figure 12 In different situations, scrolling is not processed; the remeasurement request display W7 remains on, thus emphasizing the remeasurement request display W7. Registered users who select the remeasurement button B and complete the measurement for the target user can view the recommended display screen.

[0109] (Example 4)

[0110] Figure 14 This is a diagram illustrating an example of the display control for the remeasurement request display body W8 in Example 4. Furthermore, Figure 15 This is a diagram illustrating an example of the emphasis display control of the remeasurement request display body W8 in Example 4. In this example, if the number of days elapsed since the last measurement meets the first remeasurement request interval condition, the server system 1100 causes the remeasurement request display body W8 to be formed into a pop-up window of maximized size and displayed on the recommended display screen W4. Figure 14 (a)

[0111] Next, if a swipe operation is performed on the terminal device 1500, the server system 1100 will... Figure 14 As shown in (b), the remeasurement request display W8 is configured as a floating window and displayed in the lower right corner of the recommended display screen W4. In this example, after a swipe operation, the remeasurement request display W8 is always displayed in the lower right corner of the screen, prompting the registered user to perform a remeasurement. However, the display position of the remeasurement request display W8 is not limited to the lower right corner of the screen.

[0112] Furthermore, if the number of days elapsed since the last measurement meets the second remeasurement request interval condition, the server system 1100 will emphasize the remeasurement request display body W8. In this example, if... Figure 15 As shown, the remeasurement request display body W8 is formed to be consistent with... Figure 14 (a) The same principle applies to displaying a pop-up window at its maximum size. However, server system 1100 and Figure 14 In different situations, the swipe operation is not processed, and the remeasurement request display W8 remains on, thus emphasizing the remeasurement request display W8. If a registered user selects the remeasurement button B and the measurement is completed for the target user, the recommended display screen W4 can be viewed.

[0113] (Example 5)

[0114] Figure 16 This is a diagram illustrating an example of the display control of the remeasurement request display body W9 in Example 5. Furthermore, Figure 17 This is a diagram illustrating an example of the emphasis display control of the remeasurement request display body W9 in Example 5. In this example, the server system 1100, if the number of days elapsed since the last measurement timing meets the first remeasurement request interval condition, such as... Figure 16 As shown, the remeasurement request display body W9 is formed into a pop-up window of maximized size and displayed on the recommended display screen W4.

[0115] Here, the remeasurement request display W9, which is displayed when the number of days elapsed since the last measurement meets the first remeasurement request interval condition, includes a remeasurement button B as an execution indicator and a display cancellation button CB as a display cancellation indicator. If the registered user wants to obtain measurement information again, they select the remeasurement button B. On the other hand, if no measurement information is being obtained again, the display cancellation button CB makes the remeasurement request display W9 disappear (closing the pop-up window of the remeasurement request display W9). This allows the user to view the recommended display screen W4.

[0116] Furthermore, server system 1100 will emphasize the remeasurement request display body W9 if the number of days elapsed since the last measurement meets the second remeasurement request interval condition. In this example, if... Figure 17 As shown, the remeasurement request display body W9 is formed to be consistent with... Figure 16 The same principle applies, but the pop-up window is displayed in its maximum size. However, server system 1100 is... Figure 16 Unlike other situations, the CB button was not displayed, but the W9 display was activated instead of the Cancel button. Therefore, registered users cannot... Figure 16 This avoids delaying the acquisition of measurement information. If a registered user selects the remeasurement button B and the measurement is completed for the target user, a recommended display screen W4 can be viewed. However, this is not limited to disabling the display cancellation button CB; the display cancellation button CB can also be disabled while still being displayed, creating a state where selection is impossible.

[0117] [Functional Composition]

[0118] 1. Server System

[0119] Figure 18 This is a block diagram illustrating an example of the functional configuration of server system 1100. For example... Figure 18As shown, the server system 1100 of this embodiment includes: an operation input unit 110s, a display unit 120s, a communication unit 130s, a server processing unit 200s, and a server storage unit 500s.

[0120] The operation input unit 110s is implemented using an input device such as a keyboard, mouse, or touch panel, and outputs the operation signal corresponding to the operation input to the server processing unit 200s. Figure 1 In this context, keyboard 1106 or touch panel 1108 is equivalent to this.

[0121] The display unit 120s is implemented using a display device such as an LCD (Liquid Crystal Display) or a touch panel, and performs various displays corresponding to the display signals received from the server processing unit 200s. Figure 1 In this context, the touch panel 1108 is equivalent to this.

[0122] The communication unit 130s is implemented using a wired or wireless communication device, and connects to the network 9 to communicate with external devices (such as terminal device 1500). For example, it can be implemented using a wireless communication device, modem, TA (terminal adapter), a wired communication cable connector, or control circuitry. Figure 1 In this context, communication device 1153 corresponds to this.

[0123] The server processing unit 200s can be implemented using electronic components such as a processor, GPU, ASIC, FPGA, or IC memory as its arithmetic circuit, and performs data input / output control between itself and other parts of the device, including the operation input unit 110s and the server storage unit 500s. Then, based on a predetermined program or data, operation input signals from the operation input unit 110s, and data received from the terminal device 1500, it performs various computational processes, comprehensively controlling the operation of the server system 1100. Figure 1 In this context, the control board 1150 or the CPU 1151 corresponds to this.

[0124] In addition, the server processing unit 200s includes: a user management unit 211, an online shopping function unit 213, an acquisition unit 215, a purchase target user setting unit 217, an estimation unit 219, a recommendation display control unit 221, and a remeasurement request display control unit 223.

[0125] User Management Unit 211 performs user registration processing and data management processing, and manages the data linked to the registered user ID. In this embodiment, User Management Unit 211 manages user data such as establishing associations with each registered user, and managing attribute information, measurement information, and comfort change information obtained from the user at any time.

[0126] The online shopping function unit 213 processes the provision of online shopping services. Registered users can use the online shopping function implemented according to this process to purchase wearable items (in this embodiment, short shoes worn by the user). In this embodiment, the online shopping function unit 213 responds to a product search request made by a registered user, retrieves product information specific to the user who is the intended purchaser, and displays the items to the registered user. Next, the online shopping function unit 213 displays the product information of the matching items on the terminal device 1500.

[0127] The acquisition unit 215 is a functional unit that performs data acquisition processing. It identifies the wearer associated with the registered user as the target user and acquires the target user's user data. While acquiring user data, it also uses measurement methods to measure the wearing part (foot) of the item (short shoes in this embodiment). Next, based on the measurement results obtained from the measurement methods, the acquisition unit 215 acquires measurement information and generates comfort variation information.

[0128] The purchase target user setting unit 217 is a functional unit that performs purchase target user setting processing. Based on the operation input in the terminal device 1500, it sets the purchase target user. When a registered user purchases an item worn by a user associated with them, a selection operation is performed to set that user as the purchase target user.

[0129] The estimation unit 219 is a functional unit that performs estimation processing. In this embodiment, the estimation unit 219 sets the target user as the target user according to the target user setting processing. Then, before the product information provided by the online shopping function unit 213 is displayed, the estimation unit 219 sets the item related to the product information as the estimated target item, estimates a first recommended size that meets the predetermined comfort conditions during the first comfort period, and a second recommended size that meets the comfort conditions during the second comfort period, which is later than the first comfort period, and uses these as the recommended size for the target user to wear.

[0130] The recommendation display control unit 221 is a functional unit that performs recommendation display control processing. In this embodiment, the recommendation display control unit 221 sets the target user as the target user based on the target user setting processing. Next, when displaying product information based on the online shopping function unit 213, the recommendation display control unit 221 performs recommendation display control on the terminal device 1500 for items related to the product information, displaying a first recommendation display indicating a first recommended size estimated by the estimation unit 219 and a second recommendation display indicating a second recommended size.

[0131] The remeasurement request display control unit 223 is a functional unit that performs remeasurement request display control processing. In this embodiment, the remeasurement request display control unit 223 determines the measurement timing (previous measurement timing) of the completed measurement information for the target user according to the recommendation display control unit 221. Then, the remeasurement request display control unit 223 performs the following control: if the number of days elapsed since the previous measurement timing meets the first remeasurement request interval condition, it adds a remeasurement request display to the terminal device 1500 that has undergone the recommendation display control, urging a remeasurement. In addition, the remeasurement request display control unit 223 performs the following emphasis display control: if the number of days elapsed since the determined measurement timing meets the second remeasurement request interval condition, which is a later date than the first remeasurement request interval condition, it emphasizes the remeasurement request display.

[0132] The server storage unit pre-stores, or temporarily stores, either in the 500s or during each processing session, programs used to enable the server system 1100 to operate and perform various functions, or data used during program execution. For example, this can be implemented using IC memory such as RAM or ROM, disks such as hard disks, or optical discs such as CD-ROMs or DVDs. Figure 1 In this context, IC memory 1152 or storage 1140 corresponds to this.

[0133] In addition, the server storage unit 500s stores server program 501, user management data 510, and item information 540.

[0134] Server program 501 is a program for enabling the server processing unit 200s to function as a user management unit 211, an online shopping function unit 213, an acquisition unit 215, a purchase target user setting unit 217, an estimation unit 219, a recommendation display control unit 221, and a remeasurement request display control unit 223.

[0135] User management data 510 is prepared for each registered user and stored as a corresponding account with the registered user ID to manage various data related to the provision of online shopping services. Specifically, one user management data 510 is as follows: Figure 19 As shown, it includes: the registered user ID 511, registered user name 513, user data of clothing 520, and purchase history data 531 of items such as short shoes that the registered user has purchased.

[0136] Wearing user data 520 is prepared for each wearing user associated with the registered user. In one set of wearing user data 520, a corresponding wearing user ID 521 is established to set the wearing user name 522, attribute information 523, measurement information 525, the measurement date and time (previous measurement timing) 527 related to the measurement information 525, and comfort variation information 529 for each item (short shoes in this embodiment) (see reference). Figures 4-6 ).

[0137] The item information 540 is prepared for each item and stores various data about that item. For example, in addition to various specification information or evaluation information used to generate comfort variation information 529 for that item, it includes information that is formed as item information such as price, product image, and availability and is displayed on the terminal device 1500.

[0138] 2. Terminal device

[0139] Figure 20 This is a block diagram illustrating an example of the functional configuration of the terminal device 1500. For example... Figure 20 As shown, the terminal device 1500 includes: an operation input unit 110, a display unit 120, a communication unit 130, a terminal processing unit 200, and a terminal storage unit 500.

[0140] The operation input unit 110 outputs operation input signals corresponding to various operations performed by the user to the terminal processing unit 200. For example, this can be achieved using a keyboard or mouse, push switch, joystick, touchpad, trackball, accelerometer, gyroscope, etc. Figure 2 In the middle, the directional input key 1502 or Home key 1504 and touch panel 1506 are equivalent to this.

[0141] The display unit 120 is implemented using a display device such as an LCD (Liquid Crystal Display) or a touch panel, and performs various displays corresponding to the display signals received from the terminal processing unit 200. Figure 2 In this context, the touch panel 1506 is equivalent to this.

[0142] The communication unit 130 is implemented using a wired or wireless communication device and connects to the network 9 to communicate with external devices (such as the server system 1100). It is implemented using a wireless communication device, modem, TA, a connector for wired communication cables, or control circuitry. Figure 2 In this context, the wireless communication module 1553 is equivalent to this.

[0143] The terminal processing unit 200 can be implemented using electronic components such as a processor (CPU, GPU, ASIC, FPGA, etc.) or an IC memory as its arithmetic circuit, and performs data input / output control between itself and other parts of the device, including the operation input unit 110 and the terminal storage unit 500. Next, the terminal processing unit 200 performs various arithmetic processes based on a predetermined program or data, operation input signals from the operation input unit 110, and data received from the server system 1100, and comprehensively controls the operation of the terminal device 1500. Figure 2 In this context, the control board 1550 or the CPU 1551 corresponds to this.

[0144] Furthermore, the terminal processing unit 200 includes a client control unit 260. The client control unit 260 performs various controls to enable the terminal device 1500 to function as an MMIF (Human Machine Interface). The client control unit 260 includes an operation signal transmission control unit 261 and a display control unit 263.

[0145] The operation signal transmission control unit 261 processes various data or request information to be sent to the server system 1100 according to the operation input to the operation input unit 110.

[0146] The display control unit 263 performs functions for making the reference based on the data received from the server system 1100. Figures 7-17 The recommended display screen or remeasurement request display is shown on the control of the display unit 120.

[0147] The terminal storage unit 500 may pre-store, or temporarily store, programs that enable the terminal device 1500 to operate and perform its functions, or data used during program execution. For example, this can be implemented using IC memory such as RAM or ROM, disks such as hard disks, or optical discs such as CD-ROMs or DVDs. Figure 2 In the example, the IC memory 1552 mounted on the control board 1550 is equivalent to this.

[0148] In addition, the terminal storage unit 500 stores a client program 502 (application) for enabling the terminal device 1500 to function as a client control unit 260.

[0149] [Processing flow]

[0150] Figure 21 This is a flowchart illustrating the processing flow in server system 1100. The processing described here is implemented by the server processing unit 200s reading and executing server program 501.

[0151] In this embodiment, the server processing unit 200s accepts an operation from a registered user's terminal device 1500 instructing the acquisition of measurement information. At this time, it also accepts operations specifying a clothing user as the target user. The operations accepted here include the registered user accessing... Figures 8-17 The remeasurement request display shows the selection operation of the remeasurement button (execution indicator). Next, if this operation is detected in the terminal device 1500 (step S1: YES), the acquisition unit 215 performs data acquisition processing and acquires various data, including measurement information, for the target user (step S3). If the remeasurement button selection operation has already been performed, measurement information is acquired again. The acquisition unit 215 sets / updates the clothing user data 520 related to the target user (see reference) based on the acquired data. Figure 19 ) Attribute information 523 or measurement information 525, comfort variation information 529.

[0152] Furthermore, the purchase target user setting unit 217 performs purchase target user setting processing, accepting the selection operation of the purchase target user in the terminal device 1500 of the registered user who has logged in. Next, if the purchase target user setting unit 217 detects this selection operation in the terminal device 1500 (step S5: YES), it sets the purchase target user (step S7). Then, if there is a subsequent request for product search based on the registered user, the estimation unit 219 sets the matching items as estimated target items and performs estimation processing. That is, for each estimated target item, the estimation unit 219 estimates the recommended size for the target user to wear the estimated target item based on the comfort variation information 529 related to the target user for that estimated target item (step S9). In this embodiment, the estimation unit 219 uses reference... Figures 4-6 The key points explained are as follows: a first recommended size for satisfying predetermined comfort conditions during the first comfort period, and a second recommended size for satisfying comfort conditions during the second comfort period, which is later than the first comfort period.

[0153] Next, the online shopping function unit 213 responds to the product search request and displays the product information of the matching items on the terminal device 1500 (step S11). At this time, the recommendation display control unit 221 sets the purchase target user as the target user and performs recommendation display control on the terminal device 1500 for each item related to the product information, displaying a first recommendation display of a first recommendation size for the target user and a second recommendation display of a second recommendation size for the target user, which were estimated in step S5 (step S13).

[0154] Next, the remeasurement request display control unit 223 determines the previous measurement time for the user targeted by the recommended display control in step S13 (step S15). Then, the remeasurement request display control unit 223 performs the following control: if the number of days elapsed since the previous measurement time determined in step S15 meets the first remeasurement request interval condition (step S17: YES), it adds a remeasurement request display to the terminal device 1500 that has undergone the recommended display control (step S19). Furthermore, the remeasurement request display control unit 223 performs the following emphasis display control: if the number of days elapsed since the previous measurement time determined in step S15 meets the second remeasurement request interval condition, which is a later date than the first remeasurement request interval condition (step S21: YES), it emphasizes the remeasurement request display (step S23).

[0155] Next, in step S25, an end determination is made, and until the determination is completed (step S25: NO), the process returns to step S1 and repeats the above process.

[0156] As explained above, according to this embodiment, a first recommended size that satisfies the comfort conditions when the target user wears the item during a first comfort period, and a second recommended size that satisfies the comfort conditions when the target user wears the item during a second comfort period that occurs later than the first comfort period, can be estimated. Next, a first recommended display indicating the first recommended size can be displayed on the terminal device 1500, and a second recommended display indicating the second recommended size can be displayed on the terminal device 1500 together with the first recommended display, to perform recommendation display control. At this time, the first comfort period display indicating the first comfort period can be associated with the first recommended size display, and the second comfort period display indicating the second comfort period can be associated with the second recommended size display. Thus, information indicating the size of the item that the target user can comfortably wear can be provided.

[0157] Furthermore, according to this embodiment, when a number of days has elapsed since the target user acquired the previous measurement information, based on the first remeasurement request interval condition, a remeasurement request display urging remeasurement can be additionally displayed during the recommended display control for that target user. Next, when a number of days has elapsed since the target user acquired the previous measurement information, based on the second remeasurement request interval condition, the remeasurement request display can be emphasized. Thus, when a target user urges the reacquisition of measurement information (regarding the measurement of measurement information), appropriate prompts can be made regarding the target user's recommended dimensions (first recommended dimensions and second recommended dimensions, etc.) or comfort periods (first comfort periods and second comfort periods, etc.).

[0158] The application of this invention is not limited to the above-described embodiments, and the constituent elements may be added, omitted, or changed as appropriate.

[0159] [Variation Example 1]

[0160] For example, in the above implementation, the target user's current wearing size (the size that can be comfortably worn at the current time) is basically set as the first recommended size to estimate the first comfort period. Therefore, at the timing of the recommendation display control, it is possible that the time when the target user's size increases is approaching, and the first comfort period is running out. Therefore, if the estimated first comfort period is running out, it is also possible to configure a system that displays a message recommending the purchase of a second recommended size compared to the first recommended size. This is because the first recommended size becomes unwearable immediately, while the second recommended size can be worn for a longer period. The determination of whether the remaining period is running out can be achieved by considering whether the length of the period from the timing of the recommendation display control to the end of the first comfort period meets a predetermined short period condition for determining that the remaining period is running out. The threshold for the specific length of the short period condition is not particularly limited, and it can be, for example, one month, or longer or shorter.

[0161] Furthermore, if a service is offered where items can be purchased at a predetermined trade-in price, the trade-in price can be displayed next to the first recommended size when the first comfort period is running low. The trade-in price can be used to purchase the item, and the predicted trade-in price at the point when the first comfort period has elapsed can be displayed. Even if the comfort period for the first recommended size is short, the trade-in price at the time of purchase can be shown, encouraging further purchases. Alternatively, if it is determined that the first comfort period is running low, the first recommended size can be set to one size larger to estimate the first comfort period, and the second recommended size can be set to one size larger to estimate the second comfort period.

[0162] [Variation Example 2]

[0163] Furthermore, the configuration may not be limited to displaying (1) information about the first recommended size (display of the first recommended size and the first comfort period) and (2) information about the second recommended size (display of the second recommended size and the second comfort period), but may be configured to display either (1) or (2). For example, examples include the display of the category of the displayed item, the length of the first comfort period, and the purchase history data of the registered user 531 (see reference). Figure 19 ) etc., to select any one of the components.

[0164] In terms of the specific order, for example, firstly, it is determined whether the remaining period from the time when the recommended display control is performed to the end of the first comfort period meets the predetermined long period condition, and if it is determined to be a long period, display (1) is performed. The threshold for the length of the long period condition can be appropriately set, for example, it can be set to 6 months. On the other hand, if it is determined that the remaining period of the first comfort period does not meet the long period condition, display (1) or display (2) is performed according to the category of the item. That is, for example, if the category of the item is "sports shoes" such as sneakers, it is assumed that they are worn frequently and are considered to have a relatively short lifespan, so even if the remaining period is determined to be short, it can be said that there is a sufficient possibility of purchasing the first recommended size. On the other hand, if it is a category such as "fashion shoes" that is assumed to be used less frequently than "sports shoes", it is considered that the purchase of the first recommended size is mostly postponed. Therefore, it can be determined that if the former is met, display (1) is performed, and if the latter is met, display (2) is performed.

[0165] In addition, if based on the purchase history data of registered users 531 (refer to...) Figure 19 When multiple items of the same category in the first recommended size have been purchased, or even if only one item has been purchased, and it was purchased recently (e.g., within a month or other scheduled period), the display can be set up as (2).

[0166] [Variation Example 3]

[0167] Furthermore, the above embodiment shows an example of displaying the estimated first and second recommended dimensions of each item on a recommended display screen of the terminal device 1500 (see reference). Figure 7 Alternatively, if there are other users who are associated with the registered user besides the user who is the purchaser (i.e., if multiple users are associated with the registered user), then for the other users, the first recommended size and the second recommended size are also estimated and displayed together in the recommendation display screen.

[0168] Figure 22 This is a diagram illustrating an example of a recommended display screen in this variation. Figure 22 The example shown illustrates a scenario where two users are associated with a registered user (e.g., user U1, the user selected as the purchase target, is the eldest child, and user U2, the second child, is also associated with the user). Figure 22 As shown, the recommended display screen W10 in this modified example is related to... Figure 7The recommended display screen W4 for user U1 includes an additional display area W11 for user U2. Display area W11 displays: a first recommended size D111 and a second recommended size D115 for item I4 estimated for user U2. Furthermore, a first comfort period D113 is displayed in association with the first recommended size D111, and a second comfort period D117 is displayed in association with the second recommended size D115.

[0169] in, Figure 22 The display position of the display area W11 shown is an example and is not particularly limited. For example, it can also be configured to display the information about the wearer U1 (the first recommended size and first comfort period or the second recommended size and second comfort period of the wearer U1) and the information about the wearer U2 (the first recommended size and first comfort period or the second recommended size and second comfort period of the wearer U2) vertically.

[0170] Furthermore, in Modification 3, an example is shown where the display area W11 displays information about both the first recommended size and the second recommended size for the wearer U2. However, it is also possible to configure the display area to display only the first recommended size (and the first comfort period) without displaying information about the second recommended size (and the second comfort period). Alternatively, it is possible to configure the display area to display only the second recommended size (and the second comfort period) without displaying information about the first recommended size (and the first comfort period). Furthermore, it is possible to configure the display area to display only the recommended sizes (first and second recommended sizes, etc.) and not the comfort periods (first and second comfort periods, etc.). Finally, it is possible to configure the display area to display information about the first recommended size (and the first comfort period) and the second recommended size, but not the second comfort period.

[0171] In addition, it is also possible to use the purchase history data of registered users (refer to 531). Figure 19 ), will be displayed in display area W11 (refer to Figure 22 Regarding the display for the second son's wearer U2, it is decided to display any one of the following: (1) the display of the first recommended size (display of the first recommended size and the first comfort period), (2) the display of the second recommended size (display of the second recommended size and the second comfort period), and (3) the display of both the first and second recommended sizes. For example, if the wearer U2 has already purchased an item (short shoes) of the first recommended size, it can be estimated that the likelihood of purchasing another item of the first recommended size is low. In the case described above, display (2) is used to determine the display.

[0172] Furthermore, the category of the item can be added in addition to the principles of Variation Example 2 to determine whether to display any of the above (1) to (3). For example, even if the first recommended size item has been purchased for wearing User U2, the likelihood of purchasing the same first recommended size item again may vary depending on the category of the purchased item. Specifically, if the purchased item is "sports shoes", there may be cases where the first recommended size item is purchased again for wearing User U2 for reasons such as the item has been consumed. On the other hand, if it is a category such as "fashion shoes" with a relatively low assumed frequency of use, the likelihood of purchasing the already purchased first recommended size item again is low. Therefore, it can be determined whether to display (1) or (3) if the former is met, and to display (2) if the latter is met.

[0173] [Variation Example 4]

[0174] Furthermore, if multiple users (e.g., users U1 and U2) are associated with a registered user, instead of displaying in display area W11 as in Modification 3, a configuration can be formed where the displayed object in the recommended display screen can be switched. Specifically, for example, in the relevant Figure 7 The recommended display screen W4 for user U1 is equipped with a switching button and other features, allowing users to switch the display based on their preferences. Then, by selecting the switching button on the terminal device 1500, the display of the recommended display screen W4 is changed to show either the first recommended size and first comfort period or the second recommended size and second comfort period for item I4 estimated for user U2. If the switching button is selected again, the display of the recommended display screen W4 is changed back to show either the first recommended size and first comfort period or the second recommended size and second comfort period for item I4 estimated for user U1. Since multiple user displays can be viewed on the same page, it is easy to connect to a purchase action, for example, if a registered user wants to purchase the same item from multiple users.

[0175] [Variation Example 5]

[0176] Furthermore, in the above embodiment, the first remeasurement request interval condition is set to, for example, "more than 3 months," and the second remeasurement request interval condition is set to, for example, "more than 6 months." Alternatively, the configuration can be such that the first and second remeasurement request interval conditions are set according to the target user's age (in months). For example, the first and second remeasurement request interval conditions applicable to each age in months can be preset, and the configuration can be implemented by using the first and second remeasurement request interval conditions that are appropriate for the target user's age in months.

[0177] [Variation Example 6]

[0178] Furthermore, if the target users are adults who have stopped growing, or children whose feet have stopped growing, there is no second recommended size, and therefore no end period is specified for the first comfort period. In the case described above, the first comfort period can also be structured by displaying the replacement period of the item (short shoes) as the end period. This is because short shoes are consumables and must be replaced. Therefore, no second recommended size or second comfort period is displayed.

[0179] Specifically, for example, from purchase history data 531 (reference) Figure 19 The system obtains the date and time of the item exchange and sets the end of the first comfort period after a predetermined consumption forecast period begins from that date and time. The length of the consumption forecast period can be appropriately set, for example, based on the average lifespan of short shoes. Furthermore, the length of the consumption forecast period can also be set according to the category of the purchased item. For example, a short first consumption forecast period is set for categories considered to be worn frequently (easily consumed and with a relatively short lifespan) (e.g., "sneakers"), while a longer second consumption forecast period is set for categories considered to be worn less frequently than "sneakers" (e.g., "fashion shoes").

[0180] Furthermore, if, as shown in this variation, the second recommended size and second comfort period are not displayed, the current comfort level can be displayed for the first recommended size of the item.

The remeasurement request is displayed in the control system: If the first remeasurement request interval condition is met, control is performed to display the remeasurement request display body together with the display cancellation indicator body. Furthermore, if the number of days elapsed satisfies a second remeasurement request interval condition that is a later day than the first remeasurement request interval condition, then control is performed to prevent the display cancellation indicator from being displayed and to display the remeasurement request display.

[0214] According to this configuration, if a number of days has elapsed since the last acquisition of measurement information for the target user, corresponding to the first remeasurement request interval condition, or a number of days has elapsed since the last acquisition of measurement information for the target user, corresponding to the second remeasurement request interval condition, a remeasurement request display body including an execution instruction for reacquiring measurement information can be displayed. Then, for the remeasurement request display body after the elapsed number of days corresponding to the first remeasurement request interval condition, a display cancellation instruction can be displayed together. Therefore, the remeasurement request display body at this time can be configured to be cancelable. Conversely, if a number of days has elapsed since the second remeasurement request interval condition, the display cancellation instruction can be deactivated while the remeasurement request display body is displayed. Therefore, the remeasurement request display body at this time can be configured to be non-cancellable.

[0215] In the computer system described in any one of the fourteenth to twentieth embodiments, the remeasurement request display body includes an execution instruction body for reacquiring the measurement information. The remeasurement request is displayed in the control system: If the first remeasurement request interval condition is met, control is performed to display the remeasurement request display body together with the display cancellation indicator body. Furthermore, if the number of days elapsed satisfies a second remeasurement request interval condition that is a later day than the first remeasurement request interval condition, then control is performed to invalidate the display cancellation indicator and enable the remeasurement request display to be displayed.
