Description

The present invention relates to an information processing device, an information processing method, and a program.

In recent years, there has been an increasing demand for upcycling activities, which involve creating works of art using unused items. Patent Document 1 discloses technology for managing electronic commerce between sellers who offer items and buyers.

JP 2007-323619 A

By using the system described in Patent Document 1, users can search for items to use in an artwork from among multiple items that have been put up for sale. Since various types of items can be candidates for items to be used in an artwork, users may search for items to use in an artwork without having decided on the items to be used in the artwork. In this case, since the number of items put up for sale in the system described in Patent Document 1 is enormous, it is a heavy burden for users to search for items to use in an artwork.

The present invention has been made in consideration of these points, and aims to provide an information processing device, information processing method, and program that can reduce the burden of searching for items to use in a work.

The information processing device according to the first aspect of the present invention has a storage unit that stores a database that stores, for each work created using materials including waste materials as components, the work in association with a plurality of components used to create the work, an acquisition unit that acquires item information indicating each of a plurality of items that each of a plurality of providers can provide as materials for creating the work, a reception unit that receives from a requester a selection of the type of work desired to be created, and a presentation unit that refers to the database and presents to the requester the plurality of items including each of the plurality of components used to create works of the work type.

The database may further store the creator of the work in association with the work, and the presentation unit may refer to the database and further present information regarding the creator who created the work of the work type accepted by the acceptance unit, among the multiple creators.

The reception unit may receive a selection of the items to be used in a work of the work type after the presentation unit presents the multiple items to the client, and the presentation unit may present information about the creator who created a work of the work type using the items selected by the reception unit from among the multiple creators.

The presentation unit may present to the requester a plurality of item objects corresponding to the plurality of items in a virtual space, and the reception unit may receive a selection of the item corresponding to the item object selected by the requester by the requester selecting the item object from among the plurality of item objects.

The presentation unit may present the item object in the virtual space at a position closer to a virtual reference position serving as a reference in the virtual space when the real distance from a real reference position serving as a reference in the real world to a location where the item corresponding to the item object is stored is shorter, and may present the item object in a position farther from the virtual reference position when the real distance is longer.

The presentation unit may present to the client, as information about the creator, an estimated price that would be expected if a work were requested from the creator, a transaction price for the item selected by the client, and a production cost including a transportation cost for transporting the item selected by the client from a storage location of the item to the creator's work location.

The reception unit may receive a selection of the creator from among the multiple creators from the requester, and the information processing device may further include a notification unit that notifies the creator selected by the requester of a request to create a work of the work type selected by the requester based on the item selected by the requester.

The information processing method according to the second aspect of the present invention includes the steps of: acquiring item information indicating each of a plurality of items that each of a plurality of providers can provide as materials for the creation of a work, executed by a computer; receiving from a client a selection of the type of work the client wishes to create; and, for each work created using materials including waste materials as components, referring to a database that stores the work in association with a plurality of components used to create the work, and presenting to the client the plurality of items including each of the plurality of components used to create works of the work type.

The program according to the third aspect of the present invention causes a computer to function as an acquisition unit that acquires item information indicating each of a plurality of items that each of a plurality of providers can provide as materials for the creation of a work, a reception unit that receives a selection of the type of work desired to be created from a client, and a presentation unit that refers to a database that stores, for each work created using materials including scrap materials as components, the work in association with a plurality of components used to create the work, and presents the plurality of items including each of the components used to create works of the type of work to the client.

The present invention has the effect of reducing the burden of searching for items to use in a project.

[Outline of information processing system S as a premise of the present embodiment]
First, an overview of an information processing system S that is the premise of this embodiment will be described. Fig. 1 is a diagram showing the configuration of the information processing system S. The information processing system S is a system for providing a client with a work that a creator has created using multiple items.

In private transactions such as auctions, items with commercial value (e.g., unbroken, usable items, etc.) can be circulated, but items without commercial value (e.g., broken, unusable items, food waste such as coffee grounds, soybean pulp, and egg shells, etc.) cannot be circulated. Therefore, there is a problem in that items without commercial value are discarded even though they could be used in upcycling activities.

Therefore, the information processing system S provides a service of distributing items, including items that have no commercial value, and providing works created using the items. The information processing system S has a provider terminal 1, a creator terminal 2, a requester terminal 3, and an information processing device 4.

The provider terminal 1 is a terminal used by the provider, such as a smartphone, tablet, or personal computer. The provider is a user who provides an item. The item is an item that can be provided as a material for the production of a work, such as unwanted items or waste that are no longer needed by the provider. The item may be an item that is still usable but is no longer needed by the provider (for example, an item that is not broken), or an item that cannot be used (for example, an item that is broken). The item is, for example, furniture, electrical appliances, tableware, toys, and food waste.

The creator terminal 2 is a terminal used by the creator, such as a smartphone, tablet, or personal computer. The creator is an artist who creates works using materials including waste materials, and creates the works in response to requests from clients to create the works.

The client terminal 3 is a terminal used by the client, and is, for example, a smartphone, a tablet, or a personal computer. The client terminal 3 may be a headset capable of VR (Virtual Reality) display. The client is a user who requests the creation of a work.

The information processing device 4 is a device that manages a service that provides works to requesters, and is, for example, a server. The information processing device 4 stores information about works that creators have created in the past, information about items, and information about creators who can be requested to create works.

The process in which the information processing system S provides the work W to the client C will be described below. Figure 2 is a diagram showing the flow of the process in which the information processing system S provides the work W to the client C.

First, provider P offers up item G ((1) in FIG. 2). Specifically, provider P first inputs item information indicating item G that can be provided as a material for creating work W into provider terminal 1, and provider terminal 1 transmits the item information entered by provider P to information processing device 4. Then, information processing device 4 acquires the item information from provider terminal 1 and registers item G indicated by the item information. In the example shown in FIG. 2, provider P1 offers up item G1 (a chair), and provider P2 offers item G2 (a table).

Next, client C requests the production of work W ((2) in FIG. 2). Specifically, first, the information processing device 4 presents to client C the types of works W that creator D has produced in the past, multiple items G, and multiple creators D. Then, client C performs an operation on client terminal 3 to select the type of work W that client C wishes to produce, the item G to be used in the work W, and the creator D who wishes to produce the work. Then, client terminal 3 notifies the creator terminal 2 used by the selected creator D of a request to produce work W of the selected type using the selected item G via information processing device 4. In the example shown in FIG. 2, client C requests the selected creator D to produce a work type "chair" using items G1 and G2.

Next, producer D produces work W in response to the request from client C, and provides the produced work W to client C ((3) and (4) in FIG. 2). Specifically, first, when producer D performs an operation on producer terminal 2 to accept the notified request from client C, producer terminal 2 notifies information processing device 4 of acceptance information indicating that producer D has accepted the request from client C. Note that, between client C requesting the production of work W and producer D accepting the request, negotiations for the production of work W may take place between client C and producer D. The negotiations may cover, for example, the costs associated with the production of work W, the period for the production of work W, etc.

When the information processing device 4 acquires the acceptance information from the creator terminal 2, it notifies the donor terminal 1a and the donor terminal 2b of information indicating the production location where the creator D will produce the work W, thereby causing the donor P1 and the donor P2 to deliver the items G1 and G2, respectively, to the production location. Then, when the creator D receives the items G1 and G2, he creates the work W and delivers the produced work W to the requester C.

In this way, the information processing system S can provide new uses for items G with no commercial value that have been discarded up until now. This allows the information processing system S to promote the circulation of items G with no commercial value. As a result, the information processing system S can reduce the amount of items G with no commercial value that are discarded.

[Overview of information processing system S1 according to this embodiment]
Next, an overview of the information processing system S1 in this embodiment will be described. Fig. 3 is a diagram for explaining the overview of the information processing system S1 in this embodiment. The information processing device 4 stores a work management database that stores, for each work W produced using materials including waste materials as components, the work W and a plurality of components used to produce the work W in association with each other.

In this case, first, the provider P inputs item information indicating the item G into the provider terminal 1, and the provider terminal 1 transmits the item information input by the provider P to the information processing device 4 ((1) in FIG. 3). The information processing device 4 registers the item information in the item management database ((2) in FIG. 3).

When client C performs an operation on client terminal 3 to select one type of work from among multiple types of works W previously created by creator D, client terminal 3 transmits information indicating the type of work selected by client C to information processing device 4 ((3) in FIG. 3). Then, information processing device 4 refers to the work management database and presents to client C, from among multiple items G, multiple items G each including multiple parts used to create the work W of the type of work selected by client C ((4) in FIG. 3).

In this way, the information processing system S1 can reduce the burden of searching for items G to be used in the work W.
The configuration of the information processing device 4 will be described below.

[Configuration of information processing device 4]
4 is a diagram showing the configuration of the information processing device 4. The information processing device 4 has a communication unit 41, a storage unit 42, and a control unit 43. The control unit 43 has an acquisition unit 431, a registration unit 432, a presentation unit 433, a reception unit 434, and a notification unit 435.

The communication unit 41 is an interface for connecting to a network, and is configured to include, for example, a communication controller. The storage unit 42 is a storage medium such as a ROM (Read Only Memory), a RAM (Random Access Memory), or a hard disk. The storage unit 42 stores a program executed by the control unit 43. The storage unit 42 stores an item management database that manages information about an item G, a work management database that manages information about a work W that was created by a creator D in the past, and a creator management database that manages information about the creator D.

Figure 5 is a diagram showing an example of the configuration of a database stored in the memory unit 42. The item management database shown in Figure 5 (a) stores item identification information, item type, provider identification information, offered price, and storage location in association with each other.

The item identification information is information for identifying the item G. The provider identification information is information for identifying the provider P who provides the item G. The item name may be the name of the item G or the type of item G. The offering price is the price at which the item G is offered, for example, a price set by the provider P. The storage location is the place where the item G is stored, for example, indicated by an address or location coordinates. The item management database is not limited to the example shown in FIG. 5(a), and may further store comments about the item G made by the provider P, the manufacturer of the item G, the model number of the item G, an image of the item G, a three-dimensional model of the item G, etc.

The work management database shown in FIG. 5(b) stores the type of work, the materials used, and the creator identification information in association with each other. The materials used are the materials used to create the work W, and are indicated, for example, by the item name. The creator identification information is information for identifying the creator D who created the work. The work management database is not limited to the example shown in FIG. 5(b), and may further store the title of the work given by the creator D, an image of the work W, a three-dimensional model of the work W, etc.

The creator management database shown in FIG. 5(c) stores creator identification information, creator name, and production location in association with each other. The production location is the place where creator D creates works. The creator management database is not limited to the example shown in FIG. 5(c), and may further store creator D's career history and creator D's representative works (work titles, images of works, etc.).

Returning to FIG. 4, the control unit 43 is, for example, a CPU (Central Processing Unit). The control unit 43 executes the programs stored in the memory unit 42, thereby functioning as an acquisition unit 431, a registration unit 432, a presentation unit 433, a reception unit 434, and a notification unit 435.

The acquisition unit 431 acquires, via the communication unit 41, item information indicating each of the multiple items G that each of the multiple providers P can provide as materials for the production of the work W. For example, first, each provider P inputs item information into each provider terminal 1, and each provider terminal 1 transmits the item information input by each provider P to the information processing device 4. Then, the acquisition unit 431 acquires the item information transmitted by each provider terminal 1 and the provider identification information corresponding to each provider P using each provider terminal 1.

For each item information acquired by the acquisition unit 431, the registration unit 432 registers the item information in the item management database. For example, when the acquisition unit 431 acquires item information, the registration unit 432 first generates item identification information corresponding to the item G indicated by the item information. Then, the registration unit 432 associates the generated item identification information, the donor identification information acquired by the acquisition unit 431, and the item information acquired by the acquisition unit 431, and stores them in the item management database.

Here, the information processing device 4 may attach a tag capable of acquiring location information to the auctioned item G. The tag may be, for example, a GPS (Global Positioning System) tag, a Beacon tag, or the like. For example, when the information processing device 4 registers the item G, it sets item identification information corresponding to the item G in the tag and delivers the set tag to the provider P. Then, when the provider P receives the tag, it attaches the tag to the item G. In this way, the information processing device 4 can grasp the location of the auctioned item G.

The presentation unit 433 presents various information to the client C for requesting the production of the work W. Specifically, the presentation unit 433 first transmits the various information to the client terminal 3 via the communication unit 41. The client terminal 3 then displays the various information acquired from the information processing device 4 on the display.

The reception unit 434 receives from the client C a selection of the type of work W that the client wishes to create. Specifically, first, the presentation unit 433 refers to the work management database and presents to the client C the work types of multiple works W that have been created in the past. When the client C selects a work type from the multiple work types of works W presented on the client terminal 3, the client terminal 3 transmits information indicating the selected work type to the information processing device 4. The reception unit 434 then receives the selection of the type of work W that the client wishes to create by acquiring information indicating the work type selected by the client C from the client terminal 3 via the communication unit 41.

When the reception unit 434 receives the work type, the presentation unit 433 refers to the work management database and presents to the client C a plurality of items G including each of a plurality of components used to create the work W of the work type. Specifically, the presentation unit 433 identifies a plurality of items G that can be used to create the work W of the work type selected by the client C from among the items G stored in the work management database, and presents the item information of each of the identified plurality of items G to the client C.

For example, if client C selects the work type "chair", the presentation unit 433 first refers to the work management database shown in FIG. 5(b) and identifies the used materials "chair", "table", and "shopping cart" associated with the work type "chair" as materials used to create the work type work W. The presentation unit 433 then refers to the item management database shown in FIG. 5(a) and presents client C with the item information for each of the item identification information "G0001", "G0002", and "G0005" corresponding to the identified used materials.

After the presentation unit 433 presents the item information to the client C, the reception unit 434 may accept a selection of items G to be used as components of the work W. Specifically, when the client C first selects one or more items G from the multiple items G presented on the client terminal 3, the reception unit 434 transmits item identification information corresponding to the selected items G to the information processing device 4. The reception unit 434 then acquires the item identification information from the client terminal 3 via the communication unit 41, thereby accepting the selection of items G to be used as components of the work W. The reception unit 434 may accept the selection of items G until the multiple components necessary to create the work W of the work type selected by the client C are collected, or may accept the selection of some of the items G.

The reception unit 434 may receive a selection of an item G in a virtual space in which multiple item objects corresponding to the multiple items G exist. Specifically, the presentation unit 433 first presents multiple item objects corresponding to the multiple items G to the requester C in the virtual space. Then, the reception unit 434 receives a selection of an item G corresponding to the item object O selected by the requester C by the requester C selecting an item object from the multiple item objects.

FIG. 6 is a schematic diagram of a virtual space V in which multiple item objects O exist. In the virtual space V shown in FIG. 6, a storage area for multiple item objects O and an avatar A operated by a client C are displayed. In the virtual space V, the client C can search for a desired item object O from among the multiple item objects O placed in the storage area via the avatar A. In this case, when the client C selects one or more item objects O from among the multiple item objects O via the avatar A, the reception unit 434 receives the selection of an item G corresponding to the selected item object O. In this way, the information processing device 4 allows the user to select an item G to be used in the work with a feeling of searching blindly for a desired item G in a storage area for multiple items G in the real world.

The presentation unit 433 may arrange the item object O displayed in the virtual space V according to the real distance from the real reference position to the storage location of the item G corresponding to the item object O. The real reference position is a reference position in the real world, for example, the production location of the creator D, but may be the current location of the requester C or the address of the requester C. For example, the presentation unit 433 displays the item object O at a position closer to the virtual reference position as the real distance is shorter, and displays the item object O at a position farther from the virtual reference position in the virtual space V as the real distance is longer. The virtual reference position is a reference position in the virtual space V, for example, the position in the virtual space V where the avatar A is first displayed, or the entrance to the storage location of the item object O. For example, the requester C can reduce the delivery cost of delivering the item G corresponding to the selected item object O to the production location of the creator D by selecting an item object O displayed nearby.

The presentation unit 433 may also arrange the item objects O displayed in the virtual space V in groups for each predetermined area. The predetermined area may be, for example, a prefecture, a city, a ward, a town, or a village. In this case, the presentation unit 433 may arrange the item objects O arranged in groups for each predetermined area according to the distance from the reference position to the predetermined area. In this way, the presentation unit 433 can display a group of item objects O that reflect the local characteristics, such as traditional crafts. Furthermore, the requester C can search for the desired item G in a place that is familiar to him/her (for example, his/her hometown or the location of his/her alma mater).

The avatar A displayed in the virtual space V is not limited to one person, and may be multiple people. In this case, multiple client C who respectively operate multiple avatars A may have a function for communicating through the virtual space V (e.g., chat or voice calls, etc.). In this way, the information processing device 4 allows multiple client C to select desired items G while communicating with each other.

In the above, an example has been described in which the reception unit 434 receives a selection of an item G to be used in the production of the work W from among multiple items G stored in the item management database, but this is not limited to this. For example, the reception unit 434 may receive an item G owned by the client C as the item G to be used in the production of the work W.

For example, first, after the reception unit 434 receives the work type, the presentation unit 433 refers to the work management database and presents the parts to be used to create the work W of the work type to the client C. Then, when the client C performs an operation on the client terminal 3 to input item information of the item G corresponding to the presented parts, the client terminal 3 transmits the item information to the information processing device 4. Then, the reception unit 434 receives the item G to be used to create the work W by acquiring the item information from the client terminal 3.

The reception unit 434 may receive a selection of a creator D to create the work W. Specifically, first, the presentation unit 433 presents to the requester C information on each of the multiple creators D stored in the creator management database. When the requester C selects a creator D from the multiple creators D presented on the requester terminal 3, the requester terminal 3 transmits creator identification information corresponding to the selected creator D to the information processing device 4. Then, the reception unit 434 receives the selection of the creator D to create the work W by acquiring the creator identification information from the requester terminal 3 via the communication unit 41.

The presentation unit 433 may refer to the work management database and present information about the creator D who has created the work of the work type accepted by the acceptance unit 434, among the multiple creators D stored in the creator management database. In the example shown in FIG. 5, it is assumed that the client C selects "chair" as the work type. In this case, the presentation unit 433 presents to the client C information about the creator D with the creator identification information "D0001" and "D0002" associated with the work type "chair" in the work management database, among the creator identification information "D0001", "D0002", and "D0003" stored in the creator management database. In this way, the information processing device 4 can present to the client C creators D who have experience in creating the work W of the work type that the client C wishes to create.

The presentation unit 433 may present, as information about the creator D, an image of a "chair" created by the creator D. In this way, the information processing device 4 can allow the client C to recognize what kind of work the creator D will create.

The presentation unit 433 may present information about a creator D who created a work W of the work type using an item G selected by the client C. Specifically, first, the reception unit 434 accepts a selection of the item G to be used in the work W of the work type after the presentation unit 433 presents multiple items G to the client C. Then, the presentation unit 433 refers to the work management database and presents information about the creator D who created the work W of the work type using the item G selected by the reception unit 434 from among the multiple creators D.

In the example shown in FIG. 5, assume that client C selects "chair" as the type of work and "shopping cart" as the item G. In this case, the presentation unit 433 presents to client C information on creator D with creator identification information "D0002" that is associated in the work management database with the work type "chair" and the used materials including "shopping cart" out of the creator identification information "D0001," "D0002," and "D0003" stored in the creator management database. In this way, the information processing device 4 can allow client C to recognize what type of work W creator D will create.

The presentation unit 433 may present to the requester C information about the creator D identified using the machine learning model. The machine learning model is a model trained with training data including the creator D, the type of work W created by the creator D, and the materials used in the work W. For example, when the type of work and the item G are input, the machine learning model outputs information (e.g., creator identification information) indicating one or more creators D who, among multiple creators D, have a high production frequency of works W of the input work type and a high usage frequency of the input item G as a material in the work W. The machine learning model may further output a predetermined score together with the information indicating the creator D. The predetermined score is, for example, a numerical value indicating the frequency of production and the frequency of use.

In this case, the presentation unit 433 first inputs the work type and item G selected by the client C into the machine learning model, and thereby acquires the creator identification information output by the machine learning model. The presentation unit 433 then presents to the client C information on the creator D corresponding to the acquired creator identification information, which is stored in the creator management database. When the presentation unit 433 acquires information indicating multiple creators D from the machine learning model, it may present to the client C information on all of the acquired creators D, or may present to the client C information on the top few creators D (e.g., three) with a predetermined score.

The presentation unit 433 may present to the client C, as information about the creator D, the estimated price expected when a work is requested from the creator D, the transaction price of the item G selected by the client C, and the production cost including the transportation cost for transporting the item G selected by the client C from the storage location of the item G to the work location of the creator D. The presentation unit 433 calculates, for example, a statistical value (e.g., average, median, mode, etc.) of the production cost of the type of work previously produced by the creator D selected by the client C, or a preset production cost of the creator D selected by the client C, as the estimated price expected when a work is requested from the creator D. In this way, the information processing device 4 can grasp the cost involved in producing the work in advance.

The information processing device 4 notifies the creator D selected by the requester C of a request to create a work. Specifically, when the reception unit 434 receives from the requester C a selection of a creator D from among multiple creators D, the notification unit 435 notifies the creator D selected by the requester C via the communication unit 41 of a request to create a work W of the work type selected by the requester C based on the item G selected by the requester C. More specifically, the notification unit 435 notifies the creator terminal 2 used by the creator D selected by the requester C of a request to create a work of the work type selected by the requester C based on the item G selected by the requester C via the communication unit 41. In this way, the information processing device 4 can save the requester C the trouble of directly requesting the creator D to create the work W.

[Processing flow of the information processing system S1 in this embodiment]
Next, the flow of processing of the information processing system S1 will be described. Fig. 7 is a sequence diagram showing the flow of processing of the information processing system S1. This processing is started when the presenting unit 433 refers to the work management database and transmits information indicating the work types of multiple works W created in the past to the client terminal 3 (S1).

When the client C selects a work type from among the multiple work types of the work W presented on the client terminal 3, the client terminal 3 transmits information indicating the selected work type to the information processing device 4 (S2). When the reception unit 434 acquires the information indicating the work type from the client terminal 3, the presentation unit 433 refers to the work management database and transmits item information for each of the multiple items G, each of which includes multiple components used to create the work W of that work type, to the client terminal 3 (S3).

When the client C selects one or more items G from the multiple items G presented on the client terminal 3, the item identification information corresponding to the selected items G is transmitted to the information processing device 4 (S4). When the reception unit 434 acquires the item identification information from the client terminal 3, the presentation unit 433 refers to the work management database and transmits to the client terminal 3 information on multiple creators D who have created works W of the work type using the items G indicated by the item identification information (S5).

When the client C selects a creator D from among the multiple creators D presented on the client terminal 3, the client terminal 3 transmits creator identification information corresponding to the selected creator D to the information processing device 4 (S6). The information processing device 4 then notifies the creator terminal 2 used by the selected creator D of a request to create the selected work type using the selected item G (S7).

[Modification]
In the above, an example has been described in which the information processing device 4 accepts the selection of the work type, the selection of the item G, and the selection of the creator D in this order, but this is not limiting. For example, the information processing device 4 may accept the selection of the item G, the selection of the work type, and the selection of the creator D in this order.

For example, when the reception unit 434 receives the selection of an item G, the presentation unit 433 refers to the work management database and presents to the client C the type of work W that was created using the item G whose selection was received by the reception unit 434, from among the multiple work types of the works W. After that, when the reception unit 434 receives the selection of the work type, the presentation unit 433 refers to the work management database and presents information about the creator D who created the work of the work type received by the reception unit 434, from among the multiple creators D stored in the creator management database.

[Effects of this embodiment]
As described above, when the information processing device 4 receives a selection of the type of work W desired to be produced from the client C, it refers to the work management database and presents to the client C a plurality of items G including each of a plurality of parts used to produce the work W of the work type. In this way, it is possible to reduce the burden of searching for the items G to be used in the work W.
