Description

[Technical Field]

[0001] The present invention relates to a technology for supporting the interior design of a building property. [Background technology]

[0002] When building a new office or relocating, it is common to commission an interior design firm to handle the interior design and construction of the new or relocated office. At this time, before officially placing an order, the interior design firm will listen to the client's requests, create a rough layout plan that meets those requests, and issue a quote accordingly. The client will then consider the quote and decide which interior design firm to officially place an order with. For this reason, interior design firms have to spend a lot of time and effort preparing estimates before receiving an order, and on the other hand, clients also have to wait a certain amount of time from when they communicate their needs to the interior design firm until they receive an estimate, and it also takes a long time from there for the detailed interior design to be completed.

[0003] Therefore, a technology for supporting the design of office layouts has been proposed, as disclosed in Patent Document 1 below. The following Patent Document 1 discloses a layout support device, method, and program that can appropriately support the design of a layout according to a user's intended behavior by using an activity card that links visible information, which is information including an activity indicating the user's intended behavior and an image or video corresponding to the activity, and invisible information, which is information including zoning requirements corresponding to the activity.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following embodiments of the present invention will be described with reference to the accompanying drawings. The following embodiments are merely examples, and the present invention is not limited to the configurations of the following embodiments.

[0013] Before going into detail about the interior design support device (hereinafter sometimes abbreviated as this support device) and interior design support method (hereinafter sometimes abbreviated as this support method) according to this embodiment, we will first provide an overview of the features of this support device and this support method. The present support method is a method executed by one or more computers having a memory and a processor, and the present support device is a device capable of executing the present support method. However, the hardware configuration of the one or more computers capable of executing the present support method and the present support device is not limited in any way. These hardware configurations will be described later.

[0014] This support method includes acquiring floor plan data of a building property (referred to as process A), acquiring client request information regarding the interior design of the building property (referred to as process B), acquiring multiple sets of layout plan data and estimate information corresponding to the client's requests that are output from the trained model by applying the floor plan data and the request information (referred to as process C), and processing the multiple sets of layout plan data and estimate information to be output (referred to as process D). Each of these steps is executed by one or more computers that are the executing entities of this support method.

[0015] The floor plan data acquired in step A shows at least a diagram of the building property to be the subject of interior design, sliced ​​horizontally and viewed from above. If the building property is a skeleton property with no interior work done, the floor plan data may show only the building's framework, or may show the layout of toilets, stairs, elevators, etc. for areas other than the subject area of ​​interior design (for example, common areas). Furthermore, if the building property is a vacant property, the floor plan data may show the existing interior. The floor plan data may consist of only image data or CAD (Computer Aided Design) data showing the floor plan, or may include metadata showing additional information in addition to the image data or CAD data. The format of the image data showing the floor plan is not limited, and may be a raster format such as BMP, JPEG, PNG, GIF, or TIFF, or a vector format such as PDF or SVG. There is no limitation on the method for acquiring the floor plan data in step A. The floor plan data may be generated by one or more computers that execute this support method, may be acquired from another computer via communication, or may be read from a portable storage medium.

[0016] The request information acquired in step B indicates at least the number of people or furniture that the client desires to accommodate, the type of room desired, and the budget. The number of fixtures is the number of fixtures that the client wants for the interior. "Fixtures" refers to the equipment, machinery, furniture, etc. that are placed as interior decoration, such as desks, chairs, tables, sofas, cabinets, bookshelves, partitions, copiers, multifunction printers, shredders, refrigerators, etc. The number of fixtures indicated in the request information is preferably the number of fixtures corresponding to the number of people expected to be accommodated, but it may also be the total number of all fixtures, the number of predetermined specific fixtures such as desks and chairs, or a set of the numbers of each type of fixture. The desired room type means the type of room that the client wants, such as a president's office, a conference room, an office, a break room, a bedroom, a children's room, a living room, and the like. The budget indicates the planned amount to be spent on interior design and construction. There is no limitation on the method of acquiring the request information in step B. The request information may be acquired by being input by the user, may be acquired from another computer via communication, or may be read from a portable storage medium.

[0017] The trained model used in process C can also be called a generative AI (Artificial Intelligence) model, and is composed of, for example, a combination of a computer program and parameters or a combination of multiple functions and parameters. The trained model here may be a generative AI model, and there are no restrictions on the structure or learning algorithm of the AI ​​model. For example, the trained model may be realized as a neural network (NN), deep neural network (DNN), or convolutional neural network (CNN), which has a structure in which multiple nodes are connected by edges in each of multiple layers and in which the value of each node is calculated using an activation function from the values ​​of other nodes connected to that node and the edge weights (parameters). In addition, the trained model may be composed of multiple types of AI models, such as deep generative models such as GANs (Generative Adversarial Networks) and VAEs (Variational Autoencoders), and classification models that perform natural language processing and image recognition.

[0018] The trained model used in process C receives at least floor plan data and request information as input, and outputs multiple sets of layout plan data and estimate information corresponding to the client's requests indicated by the request information. The layout drawing data output by the trained model is data showing a floor plan in which an interior design has been applied in accordance with the input request information to the floor plan shown by the input floor plan data, and shows at least the arrangement of fixtures and the floor plan. The estimate information output by the trained model indicates at least the estimated cost corresponding to the budget indicated by the input request information and the interior design indicated by the layout drawing data. This estimated cost is the total cost required to realize the interior design indicated by the layout drawing data.

[0019] The trained model outputs multiple sets of such layout drawing data and estimate information. The plurality of sets of layout plan data each correspond to the budget indicated by the input request information, and each have a different interior design. Each of the multiple sets of estimate information includes an estimated price corresponding to the budget indicated by the input request information and the interior design indicated by the corresponding layout drawing data. In other words, the trained model can generate multiple interior design patterns that correspond to the client's requests and provide layout drawing data and estimate information for the multiple interior design patterns.

[0020] The trained model may be stored in one or more computers that execute the assistance method or the assistance device itself, or in another computer. In the latter case, the execution entity of the assistance method or the assistance device can access the trained model through communication with the other computer. In step C, multiple sets of layout drawing data and estimate information corresponding to the client's requests output from such a trained model are obtained.

[0021] In step D, an output process is performed for multiple sets of layout drawing data and estimate information acquired in step C. This output process is not limited to any particular output form, as long as the multiple sets are output in a predetermined form. The output form may be display on a display device, printing using a printing device, storage in an electronic file, or transmission to another computer.

[0022] The present support device may include means for executing the above step A (first acquisition means), means for executing the above step B (second acquisition means), means for executing the above step C (model processing means), and means for executing the above step D (output processing means). These means are realized, for example, by executing a computer program stored in the memory of the present support device by the processor of the present support device.

[0023] According to this embodiment, by acquiring the floor plan data of the building property and the client's request information, it is possible to present multiple interior design layout plans that meet the client's requests, including the client's budget, along with estimate information. As a result, not only can the estimate work of the interior design contractor be significantly reduced, but it is also possible to present interior design layout plans that satisfy the client and significantly reduce the time it takes to present an estimate to the client.

[0024] The present support device and support method will be described in detail below with specific examples. <Interior design support equipment> FIG. 1 is a diagram conceptually illustrating an example of the hardware configuration of an interior design support device (the support device) 10 according to this embodiment. 1 illustrates an example in which an interior design support service is provided as a cloud service. That is, the support device 10 is communicably connected to a communication network 2 as a server device, and provides the interior design support service to a group of user terminals 5 connected to the communication network 2. However, the support device 10 may also be realized as a standalone device.

[0025] 1, the communication network 2 may be a public network such as the Internet, a Wide Area Network (WAN), a Local Area Network (LAN), a wireless communication network, etc., and may be formed by a plurality of such communication networks, or may be formed by a single communication network. However, there are no limitations on the communication form, communication protocol, etc. of the communication network 2.

[0026] The user terminal 5 may be a general computer such as a notebook or desktop PC (Personal Computer), a tablet terminal, etc. The user terminal 5 has a CPU (Central Processing Unit), memory, a display unit, a communication unit, etc., and can be connected to the communication network 2 by wired or wireless communication, and is connected to the support device 10 via the communication network 2 so as to be able to communicate with it.

[0027] The assistance device 10 is realized by a single computer in the example of Fig. 1. As shown in Fig. 1, the assistance device 10 has a CPU 11, a memory 12, a communication unit 13, an input / output interface (I / F) 14, etc., which are interconnected by a bus. The CPU 11 is a so-called processor, and may include an application specific integrated circuit (ASIC), a digital signal processor (DSP), a graphics processing unit (GPU), and the like in addition to a general CPU. The memory 12 is a RAM (Random Access Memory), a ROM (Read Only Memory), or an auxiliary storage device (such as a hard disk).

[0028] The communication unit 13 communicates with other computers via the communication network 2 and exchanges signals with other devices such as printers. In this embodiment, the communication unit 13 communicates with the user terminal 5. A portable recording medium or the like can also be connected to the communication unit 13. The input / output I / F 14 can be connected to user interface devices such as a display device 15 and an input device 16. The display device 15 is a device, such as an LCD (Liquid Crystal Display) or a CRT (Cathode Ray Tube) display, that displays a screen corresponding to drawing data processed by the CPU 11 or the like. The input device 16 is a device, such as a keyboard or mouse, that accepts input of user operations. The display device 15 and the input device 16 may be integrated and realized as a touch panel.

[0029] The hardware configuration of the present support device 10 is not limited to the example in Fig. 1. The monitoring device 10 may include other hardware elements not shown, and may not have the display device 15 or the input device 16. The number of each hardware element is also not limited to the example in Fig. 1. For example, the present support device 10 may have multiple CPUs 11. The present support device 10 may also be realized by multiple computers consisting of multiple housings.

[0030] FIG. 2 is a diagram conceptually illustrating an example of the software configuration of the interior design support device (the support device) 10 according to this embodiment. The assistance device 10 has, as software elements, an AI model 20, an information acquisition unit 21, a model processing unit 23, an output processing unit 25, etc. These software elements are realized by the CPU 11 executing a computer program stored in the memory 12. The computer program may be installed via the communication unit 13 from a portable recording medium such as a CD (Compact Disc) or a memory card, or from another device connected to the communication network 2, and stored in the memory 12.

[0031] The information acquisition unit 21 corresponds to the first acquisition means and the second acquisition means described above, and acquires floor plan data of the building property and request information of the client regarding the interior of the building property. The floor plan data and request information are as described above. For ease of understanding, an example will be given here in which the floor plan data acquired by the information acquisition unit 21 includes CAD data showing the floor plan and metadata showing incidental information about the floor plan, such as dimensions and area.

[0032] FIG. 3 is a diagram showing an example of a floor plan shown by the floor plan data acquired by the information acquisition unit 21. As shown in FIG. The floor plan illustrated in FIG. 3 shows the walls and pillars surrounding the area TA, which is the subject of interior design, as well as the layout of the common areas such as the washroom, water heater room, men's and women's restrooms, etc. In this case, the metadata included in the floor plan data preferably indicates, in addition to dimensional information such as wall length, ceiling height, and window and door size, and area information such as area TA, the type of each room in the common area, and the types and locations of structures and equipment such as windows, columns, beams, pipe spaces, meter boxes, electrical wiring and piping, lighting, and outlets. Furthermore, the metadata may indicate orientation information (north, south, east, west).

[0033] The information acquisition unit 21 may acquire image data (BMP, PDF, etc.) showing a floor plan of the interior design target and convert this image data into CAD data. The information acquisition unit 21 may also acquire CAD data showing the floor plan from another computer, etc. The information acquisition unit 21 may also generate a floor plan based on information measured by a laser rangefinder, etc., and then generate CAD data showing the floor plan from the floor plan. The information acquisition unit 21 may also convert a three-dimensional image obtained by photographing and measuring a floor of a building property with a drone camera or by measuring with a laser scanner into a two-dimensional image, and then finally convert the image into CAD data.

[0034] Fig. 4 is a diagram showing an example of an input screen for request information, etc. In the example of Fig. 4, it is assumed that the building property for which the interior design is to be performed is a property used as an office for a company. 4 on the user terminal 5, and acquires the requested information based on input on the input screen. That is, the information acquiring unit 21 also corresponds to an input processing means that displays the input screen on the display device. In this case, the interior decorator can listen to the client's requests and other matters while looking at the input screen shown in FIG.

[0035] This input screen has input fields such as budget, desired completion date, whether or not a floor plan is available, building regulations and conditions, the number of people to be accommodated, requests regarding interior design, construction information, and problems. The budget input item allows the input of a budget amount. The desired completion date can be entered by the client. For input items such as whether or not a floor plan is available, it is possible to select whether the floor plan for the interior design exists on paper, in electronic data, or not; furthermore, if the floor plan exists in electronic data, the type of data can be entered.

[0036] In the input fields for building regulations and conditions, users can freely enter text that indicates the building regulations or building conditions stipulated for the building property. In Figure 4, examples of building regulations are entered that state that fixtures that block the meter box door and fixtures that block the emergency staircase door are prohibited, and an example of a building condition is entered that the elevator load limit is 650 kg. Such information, such as building regulations and building conditions, can be called building restriction information rather than information indicating the client's requests. In this way, the input screen allows the input of building restriction information, and the input screen can be described as including an input area in which character strings indicating the building regulations or building conditions determined for the building property can be freely entered. Therefore, the information acquisition unit 21 also corresponds to a fourth acquisition means for acquiring building restriction information indicating building regulations or building conditions determined for a building property, based on an input on the input screen.

[0037] In the input field for the planned number of people to be accommodated, the initial planned number of people to be accommodated and the maximum number of people expected in the future can be input. The input items for interior design requests allow the client to select whether the building is a skeleton property or a vacant property, and also to input specific interior design requirements. In the example of Figure 4, there are input fields for whether an entrance reception is required, whether a locker room is required, whether a changing room is required, whether a president's office is required, the rank of the president's office furniture, whether a reception room is required, the rank of the reception room furniture, the number of conference rooms, the number of people each conference room can accommodate, the number of desks and chairs in the offices, the rank of the office furniture, whether free space is required, the number of cabinets / bookshelves, the number of multifunction printers, the number of shredders, the rank of the interior materials (floor), the rank of the interior materials (wall), and the rank of the interior materials (ceiling). The input screen includes a plurality of input areas corresponding to such a plurality of requests that may be included in the request information, and the information acquisition unit 21 can acquire the request information including such a plurality of specific requests based on an input to the input screen. Furthermore, as shown in Figure 4, the input screen allows for free input of requests as text. For example, requests such as "Please take soundproofing measures for the president's office, conference room, and reception room," "I want the floor to be an open space with solid floor tiles," "I want a free space large enough for about four people to rest," and "I want the wall and floor materials in the president's office and reception room to be of high quality" can be input. In this way, the request information may include text in a sentence format that indicates the client's requests.

[0038] The construction information input field allows users to input whether or not various types of construction work related to the interior of the building property are being carried out. In the example shown in Figure 4, examples of interior construction work include temporary construction, light steel construction, interior construction, fittings and fixtures, partition construction, electrical wiring construction, air conditioning and ventilation equipment construction, fire protection equipment construction, and sign construction. Temporary construction involves protecting walls and floors and erecting scaffolding, as well as cleaning and disposal of waste materials. Light steel construction involves installing the framework for walls and ceilings. Interior construction involves finishing the walls, ceilings, and floors, such as installing panels on walls made with light steel construction and laying tiles or carpet on the floors. Fittings and fixtures involve installing equipment to be attached to openings such as doors and windows. Partition construction involves assembling partitions. Electrical wiring construction involves installing not only electrical wiring but also outlets, lighting, communication cables, etc. HVAC and ventilation equipment construction involves installing and adjusting equipment such as air conditioners and ventilation fans. Firefighting equipment construction involves the installation of fire hydrants and sprinklers. Sign construction involves the installation of signs, etc. Since it is difficult for the client to decide the input items of such construction information, they may be input by the person in charge of the interior design company. The information acquisition unit 21 can acquire construction information indicating whether or not various types of construction related to such interior decoration have been carried out, based on input to the input screen. Therefore, the information acquisition unit 21 also corresponds to a third acquisition means.

[0039] The problem input field allows the client to input problems with the building property. That is, the input screen includes an input area where a character string indicating a problem with the building property can be freely input. Then, based on the input on the input screen, the information acquisition unit 21 can acquire request information that further indicates the problems with the building property that the client has. The problems here include complaints about the building property, such as "there is no storage space" or "the walls and ceilings are too uneven and it feels uncomfortable," as well as areas that need improvement.

[0040] In this embodiment, based on the user's input on the input screen, the information acquisition unit 21 can acquire at least request information including multiple requests such as the budget, desired completion date, number of people to be accommodated, number of fixtures, desired room type, problems with the building property, etc., as well as building restriction information indicating the building regulations or building conditions set for the building property, and construction information related to the interior of the building property.

[0041] FIG. 5 is a diagram conceptually illustrating each operation of learning and generating the AI ​​model 20 (trained model). The AI ​​model 20 corresponds to the trained model described above. As illustrated in Figure 5, the AI ​​model 20 in this embodiment is configured to input the above-mentioned building constraint information and construction information in addition to floor plan data and request information, and to output multiple sets of layout drawing data, feature text data and estimate information, as well as interior construction schedule information.

[0042] FIG. 6 is a diagram showing an example of a layout diagram indicated by the layout diagram data. The output layout data is as described above, and is data showing a floor plan (sometimes called a layout drawing) with an interior design based on the input request information for the floor plan of the input floor plan data, and showing at least the arrangement of fixtures and the floor plan. The layout data may be in any format as long as it can output a floor plan (layout drawing) with an interior design. The layout data may be image data in raster or vector format, or may be CAD data. In the example of Figure 6, an interior design has been applied to the floor plan shown in Figure 3. Specifically, the space is divided into four rooms: conference room R1, free space R2, storage room R3, and office R4. Office R4 is equipped with a storage shelf, two storage boxes, a multifunction printer, and 10 sets of desks and chairs. Free space R2 is equipped with one table and four chairs, and conference room R1 is equipped with one table and six chairs. These interior designs conform to the desired information input into AI model 20.

[0043] In addition, in this embodiment, request information including information on problems that the client has with the building property is input to the AI ​​model 20, and the AI ​​model 20 can output a layout drawing of an interior design that will improve such problems. Furthermore, in this embodiment, the above-mentioned building constraint information is input to the AI ​​model 20, so that the AI ​​model 20 can output a layout drawing of an interior design that conforms not only to the client's requests but also to the building regulations or building conditions indicated by the input building constraint information.

[0044] The characteristic text data is character string data that indicates characteristics of the interior design shown in the layout drawing data that is the same set. For example, the characteristic text data may be character string data that indicates representative characteristics of the interior design shown in the layout drawing data, such as "The interior space is divided into rough zones" or "The interior has an open feel." The characteristic text data may also include character string data that indicates representative characteristics and character string data that indicates details of the characteristics. For example, the character string data may include character string data that indicates details of the characteristics, such as "The floor is divided into zones, such as an office zone, a conference room zone, a president's office zone, and a reception room zone, and the layout is designed to make it easy to work by simulating the employee's movement from the time they arrive at work until they leave," or "The layout is designed to allow the space to be used freely like an office lounge, anticipating a temporary increase in employees. The layout is designed to make it easy to change the floor plan." For example, as a set of layout diagram data illustrated in FIG. 6, characteristic text data is output, which includes character string data indicating a typical characteristic, "We have taken into consideration the storage space," and character string data indicating details of the characteristic, "We have installed storage spaces and shelves in places that do not interfere with the flow of people on the floor, and have created a layout that makes it easy to take items in and out." In this embodiment, not only layout drawing data but also characteristic text data indicating the characteristics of the content design can be output, so that the characteristics of the interior design for each layout drawing can be presented to the client in an easy-to-understand manner.

[0045] The output estimate information is as described above, and indicates at least the estimated amount corresponding to the budget indicated by the input request information and the interior design indicated by the layout drawing data. In this embodiment, since construction information is also input to the AI ​​model 20 as described above, the estimated amount included in the estimate information can also be related to the presence or absence of various construction works indicated by the construction information. In this embodiment, by inputting into the AI ​​model 20 whether or not various interior construction work will be carried out, the cost of such work can also be reflected in the estimated amount, making it possible to provide a highly accurate estimated amount.

[0046] Furthermore, each of the multiple sets of estimate information output includes, in addition to the estimated amount, breakdown information including the estimated amount for each type of fixture included in the interior indicated by the corresponding layout drawing data and the estimated amount for each type of construction indicated by the construction information. Since the AI ​​model 20 can grasp the fixture types and quantities included in the interior design in order to generate it, it is possible to output a breakdown of the estimated amount for each fixture type by learning the unit price (amount) for each fixture type. Similarly, the AI ​​model 20 receives input of construction information and can output a breakdown of the estimated amount for each type of construction by learning the costs for each type of construction. In this way, not only the total estimated amount but also the breakdown information can be presented, making it easier for the client to consider the appropriateness of the estimated amount, etc.

[0047] Furthermore, because the AI ​​model 20 receives request information and construction information, including the desired completion date, it can also output interior construction schedule information that matches the desired completion date. The AI ​​model 20 can identify the type of construction work required based on the input construction information, and can generate interior construction schedule information that matches the desired completion date through learning the necessary work processes related to the interior, the order of implementation and duration for each type of construction work, etc.

[0048] In order for the AI ​​model 20 to be able to produce the output described above, a training (learning) process and an evaluation feedback process are performed on the AI ​​model 20 as shown in FIG. The training process is performed periodically using a teacher data database (DB), thereby periodically updating the AI ​​model 20. The training (learning) algorithm is not limited, and any known algorithm may be used.

[0049] To store data in the training data database, data such as layout plan data, fixture data, component data, legal data, and construction data are periodically collected from online websites and publicly available external information. The collected layout plan data includes image data or CAD data showing the layout plan, as well as metadata indicating the room type, dimensions, area, and interior design details (such as fixture placement and room layout information). The fixture data includes image data for each type of fixture and metadata indicating the dimensions, price, rank, etc. of each fixture type. The component data includes image data for each component, such as wall and ceiling components and partitions, as well as metadata indicating the dimensions, price, rank, etc. of each component. The legal data includes information on legal interior requirements corresponding to laws related to building interiors, such as the Building Standards Act, Fire Service Act, and Industrial Hygiene Act. The construction data includes information on the construction costs, average construction period, and execution order for each type of construction related to building interiors.

[0050] The original data of such teacher data may be input by an administrator or the like in addition to being collected periodically as described above. The collected layout drawing data is annotated to generate training data, which is then stored in the training data DB. For example, the annotation involves labeling or tagging the collected layout drawing data. Furthermore, various types of information, such as the collected metadata, are converted into a format suitable for input to the AI ​​model 20 and stored in the training data DB.

[0051] For example, by assigning labels corresponding to the above-mentioned legal interior conditions to layout drawing data and learning, the AI ​​model 20 can output layout drawing data showing an interior that complies with the law. The above-mentioned legal interior conditions can be incorporated into the AI ​​model 20 as a rule-based algorithm. Information on legal interior conditions can also be input to the AI ​​model 20. By using one or more of these methods, the layout drawing data output from the AI ​​model 20 can be made to comply with the law. Therefore, it can be stated that the trained model is given legal interior conditions that correspond to the laws and regulations related to the interior of buildings. The legal interior conditions include ensuring that passageways along walls are at least 120 cm wide, that passageways not along walls are at least 160 cm wide, that prescribed firefighting equipment is installed when partitions without openings in the transoms are installed in offices, and that the working space per person is 10 cm wide. 3 This includes one or more of the above areas. In this way, it is possible to provide layout drawing data that complies with not only the client's requests but also the law.

[0052] The evaluation feedback process evaluates the output from the AI ​​model 20 and causes the AI ​​model 20 to learn and update based on the evaluation results. The evaluation of the output from the AI ​​model 20 may be performed by a person or by computer processing. For example, when the AI ​​model 20 is realized as a GAN generative AI model, a process in which a classifier evaluates layout diagram data, etc. generated by a generator is repeated.

[0053] As described above, the structure of the AI ​​model 20 is not limited in any way as long as it is a generative AI model, but the AI ​​model 20 has, for example, the following functions. The AI ​​model 20 has an image recognition function, which enables the AI ​​model 20 to detect lines and shapes in the image data of the input floor plan data or the image of the CAD data, and to identify the position and shape of the area (room) to be the subject of interior design, and to identify the positions and shapes of walls, pillars, doors, windows, etc. The AI ​​model 20 also has a feature extraction and data analysis function. For example, in this function, the AI ​​model 20 analyzes image data or CAD data of the layout drawing data to be output, and identifies the type, number, and location of fixtures and equipment shown in the layout drawing, estimates the purpose of each room, etc. Furthermore, the AI ​​model 20 has a natural language generation function. In this function, the AI ​​model 20 analyzes features extracted from the layout drawing data to be output and generates natural language that indicates the analysis results. This allows the AI ​​model 20 to generate feature text data for the layout drawing data.

[0054] The model processing unit 23 corresponds to the above-mentioned model processing means, and provides input to the AI ​​model 20 and acquires output information from the AI ​​model 20. In this embodiment, the model processing unit 23 inputs floor plan data, request information, building constraint information, and construction information to the AI ​​model 20, and acquires layout drawing data, multiple sets of feature text data and estimate information, and interior construction schedule information output from the AI ​​model 20.

[0055] The output processing unit 25 corresponds to the above-mentioned output processing means, and performs output processing of the information acquired by the model processing unit 23. In this embodiment, the output processing unit 25 performs processing so that the layout drawing data, multiple sets of estimate information and feature text data, and interior construction schedule information are displayed on the display device of the user terminal 5. However, the output processing by the output processing unit 25 is not limited to such display processing, but may be a process of printing on a printing device, a file generation process of storing such information in an electronic file, or a process of transmitting the electronic file to another computer.

[0056] The output processing unit 25 can also perform processing so that estimate cover data indicating an estimate cover form and estimate itemized sheet data indicating an estimate itemized sheet form are output as estimate information. FIG. 7 is a diagram showing an example of output of estimate cover sheet data, and FIG. 8 is a diagram showing an example of output of estimate breakdown sheet data. As described above, the estimate information output from the AI ​​model 20 includes, in addition to the estimated amount, breakdown information including the estimated amount for each type of fixture included in the interior indicated by the corresponding layout drawing data and the estimated amount for each type of construction indicated by the construction information. Therefore, based on this information, the output processing unit 25 can process the estimate cover data and estimate breakdown data as illustrated in Figures 7 and 8 to be output.

[0057] The output example of quotation cover data shown in Figure 7 shows the estimated amount (total amount) as well as the construction costs for each type of work and the total cost of fixtures, etc., and the output example of quotation breakdown data shown in Figure 8 shows the breakdown of costs for each type of fixture, such as the desk, chairs, and bookshelves in the president's office, the sofa and sideboard in the reception room, and the table and chairs in the conference room, the breakdown of costs for each piece of equipment, such as the multifunction printer and shredder, and the breakdown of costs for interior materials such as the ceiling, walls, and floors. By outputting such estimate cover sheet data and estimate breakdown data, the interior decorator can save the effort of creating these documents, and the client can recognize the legitimacy and accuracy of the estimated amount.

[0058] <Interior design support method> FIG. 9 is a flowchart showing the interior design support method (the support method) according to this embodiment. This support method is executed by a computer such as the support device described above. For example, each illustrated step is executed by each of the software elements included in the support device 10. Therefore, since each step is similar to the processing content of each of the software elements included in the support device 10, details of each step will be omitted as appropriate.

[0059] First, the support device 10 (information acquisition unit 21) displays an input screen such as that shown in Fig. 4 on the user terminal 5 (S90). As a result, the person in charge of the interior design company interviews the client while looking at the input screen displayed on the user terminal 5, and inputs data into each input item on the input screen.

[0060] The information acquisition unit 21 acquires the request information based on the input on the input screen (S91). Specifically, the information acquisition unit 21 acquires the request information including a plurality of request items such as the budget, desired completion date, number of people to be accommodated, number of fixtures, desired room type, problems with the building property, etc. In the example of Fig. 4, the problems with the building property included in the request information are indicated by character string data entered into input fields that are allowed to be freely entered on the input screen.

[0061] Furthermore, the information acquisition unit 21 acquires building restriction information indicating building regulations or building conditions determined for the building property based on the input on the input screen (S92). In the example of Fig. 4, the building restriction information is indicated by character string data entered into input items that are allowed to be freely entered on the input screen. In addition, the information acquisition unit 21 acquires construction information related to the interior of the building property based on the input on the input screen (S93). On the input screen in the example of Fig. 4, it is possible to input whether or not various construction works related to the interior of the building property have been carried out, and the acquired construction information indicates whether or not various construction works related to the interior have been carried out.

[0062] If it is input that electronic data of the floor plan exists in the input item on the input screen such as whether or not there is a floor plan (S94; YES), the information acquisition unit 21 acquires the floor plan data (S96). The acquired floor plan data includes, for example, image data or CAD data showing the floor plan and metadata showing incidental information about the floor plan such as dimensions and area. On the other hand, if it is input on the input screen of the example of Figure 4 that there is a paper medium of the floor plan or that there is no floor plan (S94; NO), the information acquisition unit 21 generates floor plan data (S95) and acquires the floor plan data (S96). The generation of the floor plan data in step (S95) may be conversion from image data showing the floor plan, or conversion from a floor plan generated based on information measured by a laser rangefinder, drone camera, laser scanner, etc. Furthermore, step (S95) may be executed by a computer different from the present support device 10.

[0063] The support device 10 (model processing unit 23) inputs (applies) the request information acquired in step (S91), the building constraint information acquired in step (S92), the construction information acquired in step (S93), and the floor plan data acquired in step (S96) to the AI ​​model 20 (S97).

[0064] Then, the model processing unit 23 acquires the layout drawing data, the estimate information, the characteristic text data sets, and the interior construction schedule information output from the AI ​​model 20 in response to the above input (S98). Each of the multiple sets of layout plan data represents a layout plan with a different interior design that meets multiple requirements, such as the budget, expected occupancy, number of fixtures, desired room type, and problems with the building, as indicated by the input request information. Each of the multiple sets of estimate information includes the budget indicated by the input request information, whether or not construction is required for each type of construction indicated by the input construction information, and an estimated cost corresponding to the interior design indicated by the corresponding layout plan data, as well as breakdown information including the estimated cost for each type of fixture and the estimated cost for each type of construction indicated by the construction information. Each of the multiple sets of feature text data represents a feature of the interior design indicated by the corresponding layout plan data. The interior construction schedule information indicates a schedule that conforms to the desired completion time included in the input request information and the input construction information.

[0065] The support device 10 (output processing unit 25) performs output processing (S99) of the layout drawing data, multiple sets of estimate information and feature text data, and interior construction schedule information acquired in step (S98). In this embodiment, this information is displayed on the display device of the user terminal 5. Furthermore, as the estimate information, the output processing unit 25 performs output processing of estimate cover data indicating an estimate cover form and estimate breakdown data indicating an estimate breakdown form.

[0066] According to this support method, the interior design contractor's staff acquires request information, building constraint information, and construction information by inputting the information into an input screen displayed on the user terminal 5 while interviewing the client. Then, by inputting this information into the AI ​​model 20 together with separately acquired floor plan data, layout plan data, multiple sets of estimate information and feature text data, as well as interior construction schedule information, are acquired from the AI ​​model 20 and displayed on the display device of the user terminal 5. As a result, clients can instantly view multiple interior layout plans designed to suit their needs. Furthermore, clients can view not only the estimate cover sheet data and estimate breakdown data corresponding to each different interior layout plan, but also the interior construction schedule information. This allows clients to instantly view estimates, which previously required waiting, and quickly decide on an interior contractor. For interior contractors, too, this significantly reduces the effort and cost of creating estimates before receiving an order, and furthermore, it allows them to easily present multiple interior design plans, improving customer (client) satisfaction.

[0067] The order of execution of the steps of this support method is not limited to the example shown in FIG. The order of execution of each step can be changed as long as it does not cause any problems in terms of content. For example, step (S94) does not have to be executed by the support device 10, and steps (S95) and (S96) may be executed before step (S90), or may be executed in parallel with steps (S91) to (S93). The order of execution of steps (S91) to (S93) can also be changed, and they may be executed in parallel.

[0068] [Variations] The above is an example of an interior design support device and an interior design support method according to an embodiment of the present invention. The support device 10 and the support method described above may be partially modified as appropriate. As described in the overview of the features, at least the request information and floor plan data are input to the AI ​​model 20, and at least multiple sets of layout plan data and estimate information corresponding to the client's requests are output. For example, the AI ​​model 20 may be configured such that building constraint information and construction information are not used, and the AI ​​model 20 does not output feature text data or interior construction schedule information.

[0069] FIG. 10 is a diagram showing an example of a perspective drawing indicated by layout drawing data. Furthermore, the AI ​​model 20 can also output a perspective drawing such as that shown in FIG. 10 as layout drawing data in addition to a floor plan (layout drawing) with an interior design. A perspective drawing is a three-dimensional representation of the interior of a building property. By periodically collecting perspective drawings as layout drawing data in the training process, annotating the perspective drawings, storing them in the training data DB, and using them, the AI ​​model 20 can output perspective drawings along with layout drawings. By outputting such a perspective drawing, the interior design can be presented to the client in a way that makes it easier for them to understand. Furthermore, virtual reality (VR) data can also be output from the AI ​​model 20 and displayed on a VR device such as VR goggles, allowing the client to virtually experience the interior design in a virtual space.
