Abstract

A system for providing information about whether or not a commodity fits the body of the user is characterized by comprising means for comparing commodity data with body data and means for providing the results of the comparison to the user. The difference between the form of commodity and the form of the body is quantitatively determined by using control grid points (22) based on the FFD method for the commodity data and the body data.

Description

Product compatibility information provision system

The present invention relates to a system for determining a product suitable for a body, and also relates to sales and distribution of a product using a network.

Technology

Until now, when users select products that are suited to them, they use some size as a guide. For example, when choosing shoes, it is foot size. However, it was not clear whether the product would fit the user's body without actually trying it on. It is the same; there are various differences, such as the width of the foot and the height of the instep, even if it is the size of £. It cannot be said.

Also, when requesting to modify the shoes, the servants were telling the insults in a sensational way, saying, "Inflate a little more." As a result, the extent of the correction could not be sufficiently communicated.

In recent years, products have been sold over the Internet. However, sales of shoes, glasses, clothes, helmets, etc., where the fit with products is important, are not actively pursued. This is because the size of shoes and clothes alone is This is because the judgment cannot be made.

On the other hand, there is an FFD method as a method for deforming a three-dimensional form.

(T.W.Sederbergr Free Form Deformation of Solid Geometric Models.procedinge of ACM SINGGRAPH'86 in Computer & Graphics, 20-4,151-160 (1986)) o This FTD method transforms the target form by the following method.

• Partition the space around the target form into a grid

-Set the control grid point 22 at the intersection of this grid.

-Displace the space by moving this control grid point 2 2

• Deform the shape to match the distortion

Examples of the invention relating to the FFD method include Japanese Patent Application Laid-Open No. H8-115533 and Japanese Patent Application Laid-Open No. H10-240964. However, these inventions are used academically There is no example of using it for selling products.

Therefore, the present invention seeks to easily determine the suitability of a product and a body. In addition, it enables a more appropriate correction request, and also enables the purchase of products that require a sense of fit using a network such as the Internet with confidence. DISCLOSURE OF THE INVENTION (Desirable embodiment)

(Embodiment 1a)

Thus, the present disclosure is a system that provides information on whether or not a product is suitable for the user's body, and includes the following means.

-Means to compare product data (including wood pattern) with physical data

-Means to provide users with contrast results

Here, “product” refers to a product that the user desires to purchase and that requires a fit with the user's body. This product includes helmets, hats, glasses, masks (including dust masks, gas masks, etc.), clothing, lower garments, ommuk, gloves, accessories, shoes, etc.

"User" means anything that benefits from this system. This user includes not only general customers who purchase products, but also those engaged in manufacturing and sales replenishment, which investigate the conformity of products with customers.

The “system” in the present invention refers to an aggregate of various devices for providing information to a user. Even if the entire system is united, it may be distributed using a communication line or the like. It may be. For example, the device S for measuring the body of the user and the device s having the product data are separated.

The system is mainly composed of a computer, which is used to measure the user's body, record physical data and product data, and provide control results for each day. For example, the display area and the output section of the data to be used are increased. Next, in the present invention, product data is used as a product type. Here, “product data” is a force that refers to the data of the three-dimensional form of the product. It is not the data of the outer shape of the product, but the data of the part that comes into contact with the body. Inside In the case of a helmet, it refers to the inner form of the helmet.

Considering the case where the insole is put in the shoe, the product that comes into contact with the foot is a form of the shoe that takes the insole into account. Therefore, in such cases, the form including the insole is the product data of the shoes.

Furthermore, this product data includes not only data on the form of the product that is actually sold, but also wooden data. Here, the “wooden pattern” refers to the lumber used to make the product, which is the minus part of the part where the product is used. For example, if the product is shoes, it has a foot-shaped wooden shape, and if the product is gloves, it has a hand-shaped wooden shape. The reason why the tree pattern is also included in the product data is as follows.

-Using a wooden mold is more accurate and easier to measure 3D data.-By processing the wooden mold data, it is possible to manufacture and correct the product. It may be analog data overnight or digital data. However, considering transmission and reception using communication lines. Digital data is suitable. In addition, from the viewpoint of reducing the amount of data, it is desirable that this product data be a set of location data.

As in the past, automatic measurement and dynamic measurement may be used as the measurement method for product data. For example, a method of inputting one point at a time using a magnetic three-dimensional position sensor. Also, use the equipment described in `` Shape Measuring Method and Equipment ¾J, '' a joint application filed on April 7, 2000, H.E.A., by Aware Laboratory, Tanaka Electric Works Co., Ltd. The advantage is that the data of the three-dimensional form of the body can be measured accurately, quickly and easily.

There is no limit on the number of product data. However, in order to grasp the form of the product with a small number of data, it is desirable to use the data of the position corresponding to the anatomical feature point of the body described later.

Next, the present invention uses: ^ body data. Here, “Physical data J refers to the data of the three-dimensional form of the whole body and the body part. For example, if the product is a shoe, it means the data of the tertiary π form of the foot of the user. If present, it refers to the three-dimensional form data of the user's head. Also, this body data means the form data of the part in contact with the product. It is not necessarily limited to the part of the body-For example. Consider the case of wearing a bandaged foot and shoes. However, in this case, the form measured with gagging on the feet is the data of the rest. Note that this physical data is not limited to analog data or digital data, just like product data.

Physical data can be measured in the same way as product data. ^ There is no limit on the number of physical data. However, as in the case of the product data, it is desirable to include the data of the position corresponding to the anatomical feature point of the body in order to grasp the shape of the body with a small number of data. For example, if the product is a shoe, the shin metatarsal point 91, the calf metatarsal point 92, the kick point 93, the 1st tip point 94, and the 2nd point shown in Fig.la, Fig-lb, and Fig.lc. The finger tip point is 95, and the Koho point is 96. Here, when emphasizing the form of the width of the foot, it is desirable that this body data includes at least the shin metatarsal point 91 and the fibular metatarsal point 92. When importance is placed on the form of the length of the foot, it is desirable to include at least the heel point 93, the first finger tip point 94, and the second finger tip end point 95.

In addition, it is desirable that the following items shown in Fig. 1 should be clarified in order to efficiently grasp the shape of the feet.

-Foot length direction: 1st toe length 101, 2nd toe length 102. Inner step length 103, outer path length 104,

Inoue β 105 (This instep length is half the length of the toe 101)

• Width: Foot width 201, heel width 202, outer half foot width 203

Height direction: First finger height 301. Cuneiform bone point height (K 峄 sho) 302, Heel point ¾ 303,

End of the tip ¾ 304. End of the tip ¾ 305

-Circumference dimensions: foot circumference pole 401, foot circumference instep 402

-ft degrees: First finger pole angle 501, First finger angle 502. Fifth finger angle 503,

Inside angle 504, Outside angle 505

-Shape: Foot ffl Pol cross section, foot instep cross section

INDUSTRIAL APPLICABILITY The present invention is used to determine whether or not the body of a purchaser of a product is compatible with the product. However, in the case of using a network described later, the person who manufactures and sells the product determines the degree of conformity between the wooden mold of the company and the wooden mold of another company. It can also be used for things. Therefore, this “physical data” includes the form data of the product and the data of the wooden boat that require an appropriate judgment with the product.

Note that “product data” and “body data” in the present invention mean data representing the form, but also include data as one-dimensional daytime, such as length and width.

The present invention compares the above "product data" with "physical data J and provides the user with the result of comparison. It is easy to determine whether or not this product is suitable for oneself. Is to make

The above-mentioned “product data” and “physical data” are not particularly limited as long as they are data that accurately grasp the respective forms. However, it is preferable to provide control grid points 22 based on the FFD method for these two data. It is for the following reasons.

-To compare the difference between the form of product data that should be compared with the form of the user's body described later, it should be understood as the movement of the control grid point 22.

-Recognition of the movement pattern of the control grid point 2 2 allows an appropriate correction request.

Therefore, Fig. 2 shows the foot grid data with control grid points 22 based on the FTD method. Fig.2a is the shape of the foot to be measured. Fig.2b and Fig.2c are the body data with the control end point 22 set by the FFD method. In this figure, the intersection of the line representing the shape of the foot represents the data point 21 of the body data. On the other hand, the intersection of the grid lines represents the control grid point 22.

The setting condition of the control grid point 22 may be appropriately set according to the product form and the body shape. However, if the number of control grid points 22 is too large for the number of data, it is impossible to carry. Therefore, the number of control grid points 22 can be set within a range of 1.0 to 1.5 times the number of data, and is preferably about 1.3 times.

Also, the setting of the area where the control grid points 22 are provided may be any area that is more human than the product and the body. However, if the size of the control grid point 22 is too large compared to the product, etc., unnecessary control grid points 22 will be generated. * Therefore, the area where the control grid point 22 is provided is X coordinate 橒, Y coordinate. Coating can be applied at a culm degree of 1.0 to 1.3 times, and preferably about 1.1 times. Note that subtle distortion of the space when arranging the control grid points 22 is prevented. To achieve this, it is desirable to use a cubic B-Spline function (H8u, WHHughee, JR, Kauftnan, H.

: Direct Manipulation oi free-Form Deiormanon, Computer Graphics,

26 (2), 177-184 (1992))

Then, in the present invention, the above-mentioned “food data” is compared with “the rest of the day”. The mode of comparison may be any mode in which the user who sees the comparison result can understand the difference between the product and the body shape. Therefore, it is sufficient to determine the mode of comparison appropriately according to the characteristics of the product and the body. The following are examples of the mode of comparison. -Contrast displaying both data overlapping

， Contrast to display both side by side

-Show both data in order, staggered

Here, in the case where both data are superimposed and compared, it is desirable to use some standard (reference point, reference line). If the product is a shoe, the center line may be a line 601 connecting the heel point 93 and the first finger tip point 94, or a line 602 connecting the 蹯 point 93 and the second end point 95. Conceivable. Further, a line in the foot width direction, such as the foot width 201 or the width 202, may be used as the center line. Here, when the two points are compared based on the heel point 93, the user can easily recognize the gap on the toe side. On the other hand, the contrast based on the point on the toe side and the foot width 201 is used. In this case, the user can recognize the gap on the heel side.

Further, in the case of a form in which the product data and the body data are displayed in different colors, it is desirable that the product data and the body data are displayed in different colors. This is because the user can easily understand the difference in the form. Similarly, it is also desirable to change the color of the area where the product data and the body data do not overlap with each other, by blinking.

In the practice of the present invention, physical data and product data that have been subjected to a single comparison are recorded in a database, and when a request is made again, even a boat that reads the data from this data pace may be used. Good.

(Φ mode 1 b)

Also, the control data based on the FFD method is used for “product data” and “physical data” respectively. When the data provided with the child points 22 is used, the difference between the product and the body form can be grasped as the movement S of the control grid point 22. That is, the difference in the form can be fixed as the movement S of the control grid point 22.

The movement S of the control grid point 22 is obtained as follows. First, select the body feature point 23 from the body data. The body feature points 23 may be any points in the body data. However, choosing points that do not show the characteristics of the body shape would unnecessarily increase the amount of data, which is not appropriate. Therefore, it is desirable that these body feature points 23 are also anatomical feature points.

Next, the points of the product data corresponding to the body characteristic points 23 are specified. This specified point is defined as the product feature point. The point corresponding to this body feature point is the point of the product that this body feature point 23 contacts when it is tested.

Then, the control point 22 of the body data is moved so that the body feature point 23 becomes the product feature point. Then, the individual movement S of the control grid point 22 is described. -After obtaining the individual movement S for one point, measure the individual movement for the next point, repeat this, find the sum of the individual transfer §, and calculate this as the movement of the control case 22. I do. Here, when obtaining the movement 計算, all the body data may be calculated as the body feature points 23, or only some desired body data may be calculated as the body feature points.

Figures 3a and 3b show the control grid points 22 transferred. In this formula, the moved control grid point is represented by 24. As shown in Fig. 3, in the FFD method, moving the control grid point 22 distorts the shape of the grid, thereby deforming the form in the space.

Regarding the technology for moving the control grid point 22 and the technology for obtaining the average form by deformation, there are the following as references.

(2) Patent application for H home country

③ Japanese patent application for Japanese patent application Heisei 8—1 1 5 3 5 3 And this application is incorporated with these references (incorporated by reference), so that if the mobile is small. The product is suitable for the body. On the other hand, if the amount of movement is large, it can be determined that the product is not on vacation. Also, depending on the magnitude of this movement, the user can not only judge whether the product is suitable or not but also judge how bad it is,

Then, this comparison spinning fruit is provided to the user. There is no particular limitation on the form of provision, and a form in which the form is displayed on a screen using a display device or a form in which the form is printed on paper and provided to the user may be used. Further, a mode in which the comparison result is transmitted using a communication circuit may be employed.

In the past, it was necessary to actually try on a product in order to determine its compatibility with the product. However, using this comparison result, the user can judge the suitability of the product without actually trying it. In addition, it is possible to recognize how much the form of S differs. Furthermore, even after trying on, it is not only possible to grasp the difference as a sentimental party, but also to be able to grasp it visually.

In addition, the present invention displays the difference between the product and the body as a three-dimensional form. Therefore, it is easier to understand the difference in form than simply giving a value.

Furthermore, by using the data with control grid points 22 by the FFD method, it is possible to standardize the difference between the form of the product and the user, and it is not only easy to determine the suitability, but also the difference. Can also be provided.

(Implementation 觼 * ¾1c)

The form of the product and the form of the body that uses it are generally similar. However, some products do not match. This is because, in order to obtain a certain degree of tightening and fitting, the product is made small in consideration of the form of the product, and large in order to obtain a feeling of comfort. Also, the metaphor of the wooden mold is usually made smooth. Therefore, it is sometimes difficult to grasp the anatomical features.

In this way, when the shape of the body is significantly different from that of the product or wooden boat, or when the anatomical feature points cannot be determined from the wooden boat, it is necessary to directly compare the fragile data with the physical data. I can't. This means that the product feature points corresponding to the vacation Because it cannot be set.

Therefore, in such a case, it is desirable to use ideal data instead of product data. This ideal data is the data that is most suitable for using a certain product. The ideal data is only required to be able to set the product feature point, and the content is not particularly limited. Therefore, ideal ideals can be set in a unique way for each product. It is also possible to set a single product for each distributor or manufacturer.

For example, ideal data is created as follows

-Try on a product to many people,

-Select among the try-on people who think this product is right for you. • Ask for the body of the selected person.

-Average this body data.

In this way, even when the form of the product and the body are significantly different, the present invention can be implemented by using the ideal data.

It should be noted that the technology for averaging this physical data can also use the above-mentioned [31-28 Japanese Patent Application No. 10-240964].

(Embodiment 2)

Next, the present invention is a system for selecting an optimum product for a user from a range of a plurality of products, and includes the following means.

-Means to compare 1 product data with control grid points 22 based on the FFD method and physical data of users with control grid points 22 based on the FFD method

-Control completion-Point 22

-This control grid point 2? To select the best product based on the amount of travel

In this embodiment. "Plurality of items" means not only the products that the user has actually selected, but also includes:

'—For goods. Multiple trees

• —for one design item. Multiple products with 5% size

(Graded products) -For a product, multiple trees SH (graded wooden patterns) of different sizes And, in this example, the product data and the body data are compared, and the movement g of the control grid point 22 is determined. The movement of the control grid point 22 is obtained by the method described in the embodiment 1b. Then, when the movement § is determined for one product, the movement S of the next product is determined. This is repeated, and the movement is performed for all of the plurality of products. If the amount of movement is to be increased, the product feature point may be moved so that it matches the rest feature point. You may. In the present invention, the most suitable product is selected based on the movement S of the control grid point 22. The criteria for selecting the product are determined in consideration of the characteristics of each product. For example, if it is desirable to have a product that fits the body and one product as much as possible, determine the product that has the fewest movements. -If the product requires an appropriate amount of space, select a product with a certain range of movement g. Therefore, it is not always necessary to select the product with the least amount of movement.

In addition, a positive / negative may be provided for the movement of the control completion point 22. For example, if the product is shoes, the direction in which the body feature point is away from the center of the body is positive, and the direction toward the center is negative. As a result, it is possible to select a product to be tightened appropriately by diverting a product having a negative movement amount.

Until now, the right or wrong of the size of a product relied on the subjectivity of the profiter. Therefore, users had to try on various products and select products. However, since the present invention selects a product based on the movement g of the control grid point 22, it has the following effects.

-Systematic product selection can be performed without being based on the user's subjectivity. Therefore, a user who has erroneously selected a product can obtain a more appropriate product. -Users can select the appropriate product without trying on the product.

-It will be sufficient to try on only a few ffis determined to be optimal without trying on all products. Condition «3 a)

This investigation is a system that relies on modification of the product form, and includes the following two steps: It is characterized by the following.

-Means to compare product data with control grid points 22 based on the FFD method and ^ body data with control grid points 22 based on the FFD method

-Means for finding the movement pattern of control grid point 22

-Means for requesting correction based on this movement pattern

Means for comparing product data and body data are as described above. Next, the movement pattern of the control grid point 22 is obtained. This “movement pattern” refers to a pattern in which the control grid points 22 are moved in order to match the above-mentioned physical feature points with the product special feature points. In the case of obtaining this movement pattern, a mode may be adopted in which the i product feature points are moved so as to match the: ^ body feature points.

Then, a correction based on this movement pattern is requested. The method of this request is as follows

-The movement pattern of the control grid point 22 is directly used as a correction request.

-Request correction only for a part of the movement pattern (for example, request correction only for the hoof, correct correction only for the little finger)

-Specify the degree of the movement pattern (eg, request correction of half of the movement pattern).

-Specify part and degree and ask. And so on

This makes it possible to clarify or fix the part to be repaired and the extent of the request, instead of relying on corrections such as "a bit wider" and "narrow here". .

(¾Embodiment 3b)

It is also possible to use ideal data instead of product data. In this case, first, the movement pattern of the control grid point 22 between the grudge data and the ^ body data is obtained. Next, based on this movement pattern, a request is made for correction of the ι¾ί product or wooden form. This makes it possible to request an appropriate repair even if the product and the body are significantly different. (Implementation type 3c)

The present invention can be applied in the following manner using “ideal data”.

に A system for selecting the appropriate product from a plurality of products (including wooden molds) to the user, including the following means.

-Means to select representative products from multiple products

-Means for finding ideal data for this representative product

• Ideal data with control grid points 22 based on the FFD method and users with control grid points 22 based on the FFD method:! * Means for comparing body data

* Means for adjusting the movement of control grid point 22

-Based on the movement pattern of the control grid points 2 and 2, the representative | deform the product Φ-stage-Compare the deformed representative product with multiple products and select the appropriate product g In this implementation, first Select a representative product from multiple products. The meaning of “plural products” is the same as that described in the second embodiment. There are no particular restrictions on how to select representative products. In addition to selecting products that are medium-sized, users and third parties may arbitrarily miss.

Then, how to find the ideal data, comparison between the ideal data and the body data. How to find the movement pattern of the control grid point 2 2, and transform the proxy product based on the movement pattern of the control grid point 2 2 As described so far.

Then, the transformed representative product is compared with a plurality of iffi products, and an appropriate product is selected. The optimal method for determining the product is determined in consideration of the characteristics of each product and the wishes of the user. According to this embodiment. The difference between the shape of the product (wooden form) and the body is obvious, and the use of FFD Even if it is not possible to make a comparison, it is possible to select a suitable product (wooden shape) from a plurality of ghost products (wooden shape).

In addition, even if the system from ideal data to optimal product selection cannot be changed, it is possible to select various products by changing the method of selecting representative products.

This means that if the selected product is not satisfied with the user, the selected product can be changed simply by changing the way of selecting the substitute S product. In addition, dealers, etc., decide on representative products from their own parent points, which makes it easier to assert the characteristics of each store. That is, it is possible to change the product to be selected without changing the setting of ideal data or the program for selecting the best product. As described above, the ideal data is determined by conducting a test for each product It should not be changed for each customer. Also, changes to the program involve various errors, and it takes a lot of time and money to change and confirm execution. However, a representative product is one of a plurality of products whose data has already been recorded. In addition, the selection can be made arbitrarily by the customer, and the change does not particularly cause im. Therefore, in the case of changing the finally selected merchandise, there is an advantage that the problem associated with the change of the program does not occur.

In this way, in this implementation boat, the user himself / herself can select a favorite representative product. Hesitation is possible.

(Implementation 搽 4a)

In this way, by using the network, the user can judge the appropriateness of the product and the body without going to the shop in particular. Then, even if the product is sold on the Internet, it can be purchased with a sense of conformity with the body. As a result, sales of products on networks such as the Internet become more active.

In addition, users can receive products from multiple sellers without having to go to multiple stores, and then select the most suitable product for themselves.

The present invention may be applied to a boat in which a user stores his / her own physical data and transmits the data to a host convenience user as needed. Alternatively, the host computer may be an id having a database of the user's physical data.

If the host computer uses a desktop, users need only send information identifying themselves to the host computer when using this system, eliminating the need to measure data on vacations. , And you will not lose your physical data,

(Embodiment 4d>

The host computer 5 according to the embodiment using the network 4 is a computer connected to the network 4 having the following features. It compares the physical data and sends information that corresponds to the comparison.

Here, "the request for conformity between the body and the product j is a request from the user who has been using the product so far. This dependency includes at least information for identifying the user and the product: However, these two pieces of information do not need to be sent at the same time, and the information that identifies the user from the user terminal 1 is not available. It may be sent.

“Comparison between product data and physical data” is as described above. Further, the "quotient data" in this embodiment also includes the "ideal data".

"Send information about the comparison.", Changes in the comparison may be determined as appropriate according to the user's request. In addition to the comparison result, the most suitable product and correction request information The information on this comparison need not always be transmitted to the user terminal 1 and may be transmitted to the seller terminal 2 at the request of the user.

The computer used in the network 4 may be a Φ-computer or a group of computers that assigns each process to a plurality of computers. For example, if the network 4 is the Internet, the configuration of this convenience store 5 is composed of a WWW server that sends product information and comparison results to the user terminal 1 and the manufacturer terminal 2. In this mode, the application server that performs data comparison is independent. Also, a database that records physical data and product data.

—The application server that compares the server 5 with the application server may be independent, and the www server, the application server, and the database server may be independent Si. You may.

Further, the physical data and the product data may be stored in separate data servers, and may be read out as necessary. By dividing servers according to their functions in this way, the burden on each server is reduced and the security of the entire network is improved.

In addition, the host computer 3 does not need to be one for a plurality of user terminals 1, and even if a plurality of host computers 3 are connected to a plurality of user terminals 1. Good. In this form, users are rare! ! The service can be obtained by accessing the host computer 3 that performs the service.

With the computer described above, the system of the present invention described in the fourth embodiment can be utilized.

Industrial applicability

The present invention is intended to make it easy to judge the suitability of a product and a body. It also allows for more appropriate modification dependencies. Also, products that require a good fit can be purchased with peace of mind using a network such as the Internet.
