[0011] As an embodiment of the present disclosure, a technology for supporting a user in simulating the interior and exterior of a living space will be described. The support system of this embodiment accepts a user's specification of the design style and size of the living space, and selects the types and colors of fixtures and building materials to be installed in the living space based on the specification. The support system presents the user with an image of the living space rendered from three-dimensional shape data in which the selected fixtures and building materials are installed. This allows the user to simulate the interior and exterior of a living space with fixtures and building materials coordinated to match their preferred design style and the size of their current or future living space, simply by specifying the style and size of their preferred living space. Furthermore, a service provider offering the support system can increase business opportunities by suggesting fixtures and building materials to the user to create an attractive living space that matches the user's preferences and the size of their living space.

[0012] 1 shows the configuration of a support system according to an embodiment. The support system 1 includes a support device 100, a user terminal 200, and the Internet 2, which is an example of a communication network connecting these devices. In this embodiment, a case will be mainly described in which a simulation of a living-dining-kitchen (LDK), which is a specific area in a living space, is supported.

[0013] The support device 100 receives a design style and a size specification for the living, dining, and kitchen area from the user terminal 200. Based on the information received from the user terminal 200, the support device 100 selects the types and colors of furniture, equipment, and other installations and building materials to be installed in the living, dining, and kitchen area.

[0014] The user terminal 200 receives from the user the design style and size of the living, dining, and kitchen area, and transmits the received information to the support device 100. The user terminal 200 renders an image of the living, dining, and kitchen area in which the objects and building materials of the types and colors selected by the support device 100 are installed, and presents it to the user.

[0015] A user interface for transmitting user instructions to the support device 100 and presenting an image of the LDK to the user may be realized by a web page provided by the support device 100, or by an application executed on the user terminal 200. A function for selecting the types and colors of objects and building materials to be installed in the LDK may be executed by the support device 100 or by the user terminal 200. A function for rendering an image of the LDK in which the selected types and colors of objects and building materials are installed may also be executed by the support device 100 or by the user terminal 200.

[0016] 2 is a sequence diagram showing the procedure of the support method according to the embodiment. The support device 100 presents selection candidates for the design style of the LDK to the user terminal 200 (S10). The user terminal 200 transmits the design style of the LDK specified by the user to the support device 100 (S12). The design style may be, for example, chic, stylish, functional, bright colors, subdued colors, etc. The selection candidates for the design style may be presented only by text, only by images, or both.

[0017] The support device 100 presents selection candidates for the size of the LDK to the user terminal 200 (S14). The user terminal 200 transmits the size of the LDK specified by the user to the support device 100 (S16). The selection candidates for the size of the LDK may be shown numerically, or may be shown as a diagram or a floor plan, or may be shown as both. In addition to the size of the LDK, the support device 100 may also accept the shape, floor plan, positions of walls and windows, and shapes and positions of installed objects such as a kitchen and dining table.

[0018] The support device 100 selects the types and colors of the fixtures and building materials to be installed in the LDK based on the information received from the user terminal 200 (S18). The support device 100 selects the types and colors of the fixtures and building materials to be installed in the LDK by referring to a database that stores the design style of the LDK, the size of the LDK, and the types and colors of the fixtures and building materials that match the design style and size of the LDK. For example, in the case of a large LDK, an island-type kitchen, a large dining table, a spacious sofa, etc. may be selected. In the case of a small LDK, furniture that can efficiently utilize the space, and light-colored flooring and wall materials that can make the LDK appear larger, etc. may be selected.

[0019] The support device 100 transmits data indicating the type, color, and installation location of the selected installations and building materials, as well as three-dimensional shape data of the living, dining, and kitchen area, the installations, and the building materials, to the user terminal 200 (S20). The user terminal 200 uses the data acquired from the support device 100 to generate three-dimensional shape data of the living, dining, and kitchen area in which the selected installations and building materials are installed. The user terminal 200 generates an image of the living, dining, and kitchen area by setting a viewpoint position and a line of sight and rendering the generated three-dimensional shape data (S22). The user terminal 200 displays the generated image on a display device (S24). When the user receives an instruction from the user to change the viewpoint position or line of sight, the user terminal 200 changes the viewpoint position or line of sight and re-renders the three-dimensional shape data of the living, dining, and kitchen area, thereby updating the image of the living, dining, and kitchen area. This allows the user to simulate the proposed image of the living, dining, and kitchen area, tailored to their preferences and the size of the living, dining, and kitchen area, by changing the viewpoint position and line of sight.

[0020] When the support device 100 receives an instruction from the user to change the type, color, etc. of an installed object or building material (S28), it changes the type and color of the installed object or building material (S30). At this time, the support device 100 also changes the type and color of other installed objects and building materials so that the entire LDK has a layout and color tone that matches the design style and size of the LDK. If the user changes the types and colors of multiple installed objects and building materials separately, the layout and color tone tend to lack unity. However, by having the support device 100 automatically change the types and colors of other installed objects and building materials to match the changed types and colors of the installed objects and building materials, it is possible to simulate a LDK that has a unity that matches the design style and size of the LDK.

[0021] If there are any installed objects or building materials that will serve as the basis for the total coordination of the living, dining, and kitchen area, the user can specify the reference objects in advance to the support device 100 (S26). For example, if the user wants to renovate the living, dining, and kitchen area without changing the flooring material, or if the user wants to coordinate the entire living, dining, and kitchen area based on a favorite system kitchen, the user can specify the flooring material or system kitchen as the reference object. In this case, the support device 100 does not change the type or color of the specified reference object, but changes the types and colors of other installed objects and building materials to match the type and color of the reference object.

[0022] The support device 100 transmits data indicating the types and colors of the changed installed objects and building materials to the user terminal 200 (S32). The user terminal 200 changes the types and colors of the installed objects and building materials in the three-dimensional shape data of the living, dining, and kitchen in accordance with the data acquired from the support device 100, and generates an image of the living, dining, and kitchen by rendering the changed three-dimensional shape data (S34). The user terminal 200 displays the generated image on a display device (S36). This allows the user to seamlessly execute a simulation of the layout of the installed objects and a simulation of the colors of the installed objects and building materials, thereby improving user convenience.

[0023] 3 shows the configuration of an assistance device 100 according to an embodiment. The assistance device 100 includes a communication device 101, a display device 102, an input device 103, a processing device 110, and a storage device 160. The assistance device 100 may be a server device, a device such as a personal computer, or a portable terminal such as a mobile phone terminal, a smartphone, or a tablet terminal.

[0024] The communication device 101 controls communication with other devices. The communication device 101 may perform communication using any wired or wireless communication method. The display device 102 displays a screen generated by the processing device 110. The display device 102 may be a liquid crystal display device, an organic EL display device, or the like. The input device 103 transmits instructions input by a person in charge to the processing device 110. The input device 103 may be a mouse, a keyboard, a touchpad, or the like. The display device 102 and the input device 103 may be implemented as a touch panel.

[0025] The storage device 160 stores programs, data, etc. used by the processing device 110. The storage device 160 may be a semiconductor memory, a hard disk, etc. The storage device 160 includes an installation database 161, a building material database 162, and a performance information storage unit 163.

[0026] The installation object database 161 stores the type, name, color, design, size, price, function, specifications, three-dimensional shape data, etc. of products such as kitchens, tables, chairs, cupboards, sofas, etc. that can be installed in the living, dining, and kitchen area. The installation object database 161 stores information such as the design style and size of the living, dining, and kitchen area, and the type and color of installation objects that match the design style and size of the living, dining, and kitchen area, in association with each other.

[0027] The building material database 162 stores the types, names, colors, patterns, designs, sizes, prices, specifications, three-dimensional shape data, etc. of building materials that can be installed on the floors, walls, ceilings, pillars, etc. of the living, dining, and kitchen area. The building material database 162 stores information such as the design style of the living, dining, and kitchen area, the size of the living, dining, and kitchen area, and the types and colors of building materials that match the design style and size of the living, dining, and kitchen area, in association with each other.

[0028] The performance information storage unit 163 stores information on the objects and building materials installed in the LDK simulated by the user, the design style and size of the LDK set at the time of the simulation, and an ID for uniquely identifying the information. The performance information storage unit 163 may further store information on the objects and building materials selected by the support device 100, a history of changes made by the user, and the like.

[0029] The processing device 110 includes a design style receiving unit 111, a size receiving unit 112, a selection unit 113, a reference object receiving unit 114, a change receiving unit 115, a change unit 116, an estimate processing unit 117, a purchase processing unit 118, a recording unit 119, a performance information reading unit 120, and a learning unit 121. These components are realized in hardware by a CPU, memory, circuits, other LSIs, etc. of any computer, and in software by programs loaded into memory, etc., but the diagram depicts functional blocks realized by the cooperation of these components. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various ways, such as by hardware alone or a combination of hardware and software.

[0030] The design style receiving unit 111 presents selection candidates for the LDK design style to the user terminal 200 and receives the LDK design style designated by the user.

[0031] The size receiving unit 112 presents selection candidates for the size of the LDK to the user terminal 200 and receives the size of the LDK designated by the user.

[0032] The selection unit 113 selects the types and colors of the objects and building materials to be installed in the living / dining / kitchen kitchen based on the design style and size of the living / dining / kitchen kitchen received from the user terminal 200. The selection unit 113 may select the types and colors of the objects and building materials to be installed in the living / dining / kitchen kitchen by referring to the object database 161 and the building material database 162. The selection unit 113 may select the types and colors of the objects and building materials to be installed in the living / dining / kitchen kitchen using a selection algorithm learned by the learning unit 121 (described later). The selection unit 113 transmits to the user terminal 200 data indicating the types, colors, installation positions, etc. of the selected objects and building materials, as well as three-dimensional shape data of the living / dining / kitchen kitchen, the objects, building materials, etc.

[0033] The reference object receiving unit 114 receives from the user terminal 200 the designation of a reference object that serves as a reference for changing the type and color of an installed object or building material.

[0034] The change receiving unit 115 receives, from the user terminal 200, instructions to change the type and color of the installed objects and building materials.

[0035] The change unit 116 changes the type and color of the installed object or building material in accordance with the change instruction received by the change receiving unit 115. The change unit 116 also changes the type and color of other installed object or building material so that the layout and color tone match the design style and size of the living, dining, and kitchen area as a whole. For example, in an living, dining, and kitchen area where a unified design style is set and a white-based kitchen and light beige flooring are selected, when the kitchen is changed to a black-based kitchen, the change unit 116 may change the color of the flooring to dark brown to match the color of the kitchen. When the reference object receiving unit 114 receives the designation of a reference object, the change unit 116 does not change the type and color of the specified reference object, but changes the type and color of other installed object or building material to match the type and color of the reference object. The change unit 116 transmits data indicating the type and color of the changed installed object or building material to the user terminal 200.

[0036] The estimate processing unit 117 calculates the estimated price of the installation or building material selected by the selection unit 113 or changed by the change unit 116 by referring to the installation database 161 or the building material database 162, and presents it to the user terminal 200.

[0037] When a request is received from the user terminal 200 to purchase an installation or building material selected by the selection unit 113 or changed by the change unit 116, the purchase processing unit 118 executes processing necessary for the purchase, such as settling the price and arranging for delivery of the product. The purchase processing unit 118 may request the sale of the installation or building material by transmitting information about the installation or building material that the user wishes to purchase to a server that sells the installation or building material.

[0038] The recording unit 119 records information on the installations and building materials selected by the selection unit 113 or changed by the change unit 116 as performance information in the performance information holding unit 163. The recording unit 119 assigns an ID to the performance information and notifies the user terminal 200. The recording unit 119 stores information on the installations and building materials selected by the selection unit 113 and information on the installations and building materials changed by the change unit 116 in association with the ID in the performance information holding unit 163.

[0039] When the user terminal 200 requests that the performance information stored in the performance information storage unit 163 be read, the performance information reading unit 120 acquires the performance information ID from the user terminal 200 and reads the performance information corresponding to the performance information ID from the performance information storage unit 163. This allows the user to read the performance information at a later date and resume the simulation, or to read the performance information using another terminal device and execute the simulation.

[0040] The learning unit 121 uses the information stored in the performance information storage unit 163 as learning data to learn a selection algorithm for selecting the types and colors of fixtures and building materials to be installed in the living / dining / kitchen kitchen based on the design style and size of the living / dining / kitchen kitchen. The learning unit 121 may learn the selection algorithm by unsupervised learning, or may learn the selection algorithm by supervised learning using the information stored in the performance information storage unit 163 as training data. This makes it possible to generate a selection algorithm that reflects information about a living / dining / kitchen kitchen actually simulated by the user, thereby making it possible to propose an attractive living / dining / kitchen kitchen that better suits the user's preferences.

[0041] The support device 100 may support simulation of the interior and exterior of not only the living, dining, and kitchen area, but also other areas of the living space, such as living rooms, bedrooms, bathrooms, washrooms, entrances, and exteriors including the exterior. When simulation of multiple areas is possible, the support device 100 may make information received from the user for selecting the type and color of installations and building materials to be installed in a specific area available for selecting the type and color of installations and building materials to be installed in another area of ​​the living space. This allows for seamless simulation of multiple areas of the living space and comprehensive coordination of those areas, thereby improving user convenience.
