Description

[Technical Field]

[0001] The present invention relates to a computer system, a program, and a method for supporting renovation. [Background technology]

[0002] A system has been proposed for matching users considering renovating a home or facility with contractors who will undertake the renovation work. For example, Japanese Patent Application Laid-Open No. 2023-042108 (Patent Document 1) discloses a device that supports matching customers who wish to renovate with contractors. This device discloses public information from the renovation application information to contractors and accepts requests for orders. Contractors who wish to receive the order are provided with the application information and candidate building material information that indicates candidate building materials to be used in the construction, created based on an image of the renovation work.

[0003] Japanese Patent Publication No. 2023-106054 (Patent Document 2) discloses a renovation matching system. This system includes a user-side device 1, a craftsman-side device 4, a product order-receiving device 5, and a management server 2. The management server 2 allows the craftsman-side device 4 to view a request for an estimate. In response to the request for an estimate, the craftsman-side device 4 transmits an estimate required for the construction work to the management server 2. The user-side device 1 selects a craftsman to be commissioned to carry out the construction work from the submitted estimates. The selected craftsman-side device 4 can then order materials to be used in the construction work from the product order-receiving device 5 via the management server 2.

[0004] Japanese Patent Publication No. 2023-102135 (Patent Document 3) discloses a business matching system in which a client places an order directly with an engineer without going through a management company, even when the request requires multiple types of engineers. The management server sends the received request information to a coordinator terminal if it contains multiple pieces of business information, or to an engineer terminal if it contains only one piece of business information. If the request information contains multiple pieces of business information, the management server divides the request information into individual pieces of business information in response to a request from the coordinator terminal, and sends the divided individual pieces of business information to the engineer terminal. When business application information is received from the engineer terminal, it is integrated to generate integrated business application information and sent to the client.

[0005] [Patent Document 1] Japanese Patent Publication No. 2023-042108 [Patent Document 2] Japanese Patent Publication No. 2023-106054 [Patent Document 3] Japanese Patent Publication No. 2023-102135 Summary of the Invention [Problem to be solved by the invention]

[0006] Interior finishing materials, such as flooring, wall coverings, and baseboards, require installation by contractors, builders, craftsmen, and other professionals. Therefore, rather than users purchasing them themselves, it was common for contractors to undertake the entire renovation project, from procurement to installation. For this reason, conventional renovation matching systems typically require users to select a contractor, who then undertakes the entire renovation project, from purchasing the interior finishing materials to installation. In other words, in conventional renovation matching systems, interior finishing materials are selected in conjunction with the contractor, limiting the user's range of choices. Additionally, the appropriateness of the respective costs for the interior finishing materials and the installation costs for installing the interior finishing materials is unclear, causing users to worry about the price when considering renovation work.

[0007] Therefore, the present invention provides a system, program, and method that makes it easy for users who wish to renovate to select the materials and contractor for the renovation separately. [Means for solving the problem]

[0008] The renovation support system in an embodiment of the present invention comprises a material selection receiving unit that presents information on materials indicated in renovation material data stored in a memory unit to a user, accepts a material selection from the user, and stores the material selected by the user in the memory unit; a contractor data receiving unit that accepts input of information on each contractor from multiple contractors who are capable of carrying out the renovation and stores it as contractor data in the memory unit; a contractor information supply unit that extracts information on contractors that meet certain conditions from the contractor data including information on multiple contractors and supplies it to the user; and a contractor selection receiving unit that accepts from the user a selection of at least one contractor from the contractors indicated in the information supplied to the user by the contractor information supply unit, and stores the contractor selected by the user in the memory unit. [Effects of the Invention]

[0009] According to the present invention, a user who wishes to remodel can easily select the materials and contractor for the remodeling separately. [Brief explanation of the drawings]

[0011] (Configuration 1) The renovation support system in an embodiment of the present invention comprises a material selection receiving unit that presents information on materials indicated in renovation material data stored in a memory unit to a user, accepts a material selection from the user, and stores the material selected by the user in the memory unit; a contractor data receiving unit that accepts input of information on each contractor from multiple contractors who are capable of carrying out the renovation and stores it as contractor data in the memory unit; a contractor information supply unit that extracts information on contractors that meet certain conditions from the contractor data including information on multiple contractors and supplies it to the user; and a contractor selection receiving unit that accepts from the user a selection of at least one contractor from the contractors indicated in the information supplied to the user by the contractor information supply unit, and stores the contractor selected by the user in the memory unit.

[0012] According to the renovation support system of the above configuration 1, the user can select the desired materials from among the renovation materials indicated by the material data. In addition, multiple contractors can input their respective information as contractor data. The user can select a contractor from among the multiple contractors who meet the conditions. The materials and contractors selected by the user are each stored in a memory unit. This makes it easy for users who wish to renovate to select renovation materials and contractors separately.

[0013] (Configuration 2) In the above configuration 1, the renovation support system may further include a selected material information providing unit that provides information about the materials selected by the user to a contractor selected by the user. This allows the user to share information about the selected materials with the contractor. Therefore, both the user and the contractor can communicate with each other toward ordering construction, such as explanations, negotiations, and estimates, taking into account the selected materials.

[0014] (Configuration 3) In the above configuration 1 or 2, the renovation support system may further include a construction ordering unit that executes an ordering process to order construction from a contractor selected by the user in response to a construction ordering instruction from the user, and a material delivery ordering unit that executes a process to request or order sample delivery of the selected materials in response to an instruction from the user to order materials or send samples. This makes it easy for the user to separately select the materials and construction for the renovation and request or order sample delivery. The renovation support system may include at least one of the construction ordering unit and the material delivery ordering unit.

[0015] (Configuration 4) In any of the above configurations 1 to 3, the material selection receiving unit may include an image acquisition unit that acquires a renovation location image of the location where the user wishes to renovate, a material area recognition unit that recognizes a material placement area in the renovation location image where renovation materials will be placed, and a sample image display unit that generates a sample image in which an image of the material specified by the user is superimposed on the material placement area of ​​the renovation location image and displays it to the user. This allows the user to select materials while viewing a sample image of how the specified material will look when placed in the renovation location. This makes it easier for the user to select materials that are suitable for the renovation location. Note that a renovation support system that includes a material selection receiving unit that includes a renovation location image acquisition unit, a material area recognition unit, and a sample image display unit, and the material delivery ordering unit, is also included in an embodiment of the present invention.

[0016] In any of the above configurations 1 to 4, the material selection receiving unit may extract one or more materials from the plurality of materials indicated by the material data based on material conditions related to the material specified by the user, and display them in a selectable manner. This allows appropriate materials that meet the conditions specified by the user to be extracted and presented to the user. This makes it easier for the user to select a material that meets their needs. The material conditions specified by the user may be, for example, conditions related to at least one of the location where the material is used, the properties or functions of the material, and the appearance of the material.

[0017] In any of the above configurations 1 to 4, the builder data receiving unit may receive input of information including a fee difference period indicating a period during which the construction fee differs from other periods as information about each builder. The builder information supply unit may supply the builder information including a fee difference period indicating a period during which the construction fee differs from other periods to the user.

[0018] This allows the builder to set different fee structures depending on the time of year. For example, the builder can set fees for off-seasons to be lower than fees for busy periods, making it easier to receive orders during off-seasons. The user can request construction work at a time when fees are lower. As such, the period of different fees may include, as an example, at least one of a busy period when construction fees are higher than other periods and an off-season when construction fees are lower than other periods. Note that a renovation support system equipped with the builder data receiving unit, builder information supply unit, and builder selection receiving unit is also included in an embodiment of the present invention.

[0019] In any of the above configurations 1 to 4, the builder information supply unit may extract information on builders that meet conditions including the user's desired construction time from the builder data and supply it to the user. In this case, information indicating whether the user's desired construction time falls within a builder's fee difference period may be supplied to the user. This allows the user to know whether the user's desired construction time falls within a builder's fee difference period.

[0020] The renovation support program in an embodiment of the present invention causes a computer to execute the following steps: a material selection acceptance process that presents information on materials indicated by renovation material data stored in a memory unit to a user, accepts a material selection from the user, and stores the material selected by the user in the memory unit; a contractor data acceptance process that accepts input of information on each contractor from multiple contractors who are capable of carrying out the renovation and stores the information as contractor data in the memory unit; a contractor information supply process that extracts information on contractors who meet certain conditions from the contractor data containing information on multiple contractors and supplies the information to the user; and a contractor selection acceptance process that accepts from the user a selection of at least one contractor from the contractors indicated by the information supplied to the user in the contractor information supply process and stores the contractor selected by the user in the memory unit.

[0021] A renovation support method according to an embodiment of the present invention includes the following steps executed by a computer: a material selection receiving step of presenting information on materials indicated by renovation material data stored in a storage unit to a user, receiving a material selection from the user, and storing the material selected by the user in the storage unit; a contractor data receiving step of receiving input of information on each contractor from multiple contractors capable of renovating the home and storing the information as contractor data in the storage unit; a contractor information supply step of extracting information on contractors that meet certain conditions from the contractor data containing information on the multiple contractors and supplying the information to the user; and a contractor selection receiving step of receiving from the user a selection of at least one contractor from the contractors indicated by the information supplied to the user in the contractor information supply step and storing the contractor selected by the user in the storage unit.

[0022] For example, the renovation targeted by the renovation support system may be a renovation of interior finishing materials. The materials for the renovation may be interior finishing materials. The interior finishing materials may include, for example, at least one of flooring, wall coverings, baseboards, frames, moldings, and fittings. Examples of flooring materials include carpet, vinyl flooring, and wood-based flooring. Examples of carpet include tile carpet and roll carpet. Vinyl flooring is defined in JIS A5705:2016 and includes floor tiles and floor sheets. Examples of wall coverings include wallpaper, waist-mounted walls, and tuck sheets. Fittings are openable and closable components that separate rooms or rooms from the outside. Examples of fittings include doors, sliding doors, windows, window frames, shoji screens, and sliding doors. Fittings are decorative or finishing materials with an elongated shape. Examples of molding materials include ceiling moldings that cover the boundary between a ceiling and a wall, and trim materials that are provided at the edges or boundaries of flooring, wall coverings, and other interior finishing materials.

[0023] Furthermore, different contractors handle different types of interior finishing materials. Interior builders handle, for example, carpets, vinyl flooring, wall coverings, baseboards, frames, and moldings, while carpenters handle, for example, wood flooring and fixtures. Carpenters are capable of work involving structural changes to the renovation site. In the present invention, materials such as carpets, vinyl flooring, wall coverings, baseboards, frames, and moldings, which are primarily handled by interior builders, are referred to as interior materials. Interior materials can be installed through work that does not involve structural changes to the renovation site. Interior materials are preferably used as interior finishing materials in the renovation support system of the present invention. This allows users to easily carry out simple renovations that do not require major structural changes to the home, such as changing the room layout through carpentry work.

[0024] A builder may be an individual such as a technician or craftsman, or may be a builder who performs construction work as a business, such as a construction company, renovation contractor, house manufacturer, or material or equipment manufacturer. A user is a person who desires renovation, and may be referred to as a customer, builder, or consumer. Note that people who desire renovation also include corporations.

[0025] (System configuration example) Fig. 1 is a functional block diagram showing an example of the configuration of a renovation support system in this embodiment. The renovation support system 10 shown in Fig. 1 (hereinafter sometimes simply referred to as "support system 10") provides a function for a user who wishes to renovate to select materials for renovation, a function for presenting the user with information on the contractor entered by the contractor, and a function for the user to select a contractor. In other words, the user's selection of materials, the contractor's input of information and the presentation of contractor information to the user, and the user's selection of a contractor can all be performed on a single platform provided by the support system 10.

[0026] The support system 10 is capable of communicating with a user terminal 30, a contractor terminal 40, and a material supplier system 50. The support system 10 is capable of accessing a memory unit 20. The memory unit 20 stores material data, contractor data, selected material data, and selected contractor data. The memory unit 20 may be included in the support system 10 as a component of the support system 10. The support system 10 includes a material selection receiving unit 11, a contractor information supply unit 12, a contractor data receiving unit 13, a contractor selection receiving unit 14, a selected material information providing unit 15, a construction ordering unit 16, and a material delivery ordering unit 17.

[0027] The material selection receiving unit 11 presents material information from the material data to the user and accepts the user's material selection. The materials selected by the user are stored in the memory unit 20 as selected material data. The contractor data receiving unit 13 accepts input of contractor information from multiple contractors and stores it in the memory unit 20 as contractor data. The contractor information supply unit 12 extracts information on contractors that meet the conditions from the contractor data and provides it to the user. The contractor selection receiving unit 14 accepts the user's selection of the contractor indicated by the information provided to the user. The contractor selected by the user is stored in the memory unit 20 as selected contractor data. By having the support system 10 equipped with the material selection receiving unit 11, contractor information supply unit 12, contractor data receiving unit 13, and contractor selection receiving unit 14, the user can individually select the materials to be used for renovation and the contractor for the renovation on the same platform.

[0028] The selected material information providing unit 15 supplies the material selected by the user, i.e., information on the selected material, to the selected builder, who is the builder selected by the user. The process of supplying the information on the selected material to the selected builder may be, for example, a process of allowing the selected builder to access the information on the selected material. As an example, data for accessing data indicating the selected material is supplied to the builder terminal 40 of the selected builder. Alternatively, the process of supplying the information on the selected material to the selected builder is executed by sending data indicating the selected material to the builder terminal 40 of the selected builder. The selected material information providing unit 15 may supply the selected material to a builder selected by the user and authorized or instructed by the user to provide information.

[0029] The construction ordering unit 16 executes an ordering process to order construction from a contractor selected by the user in response to a construction ordering instruction from the user. The construction ordering unit 16 accepts a construction ordering instruction from the user via the user terminal 30. The construction ordering instruction includes, for example, information indicating the contractor to be ordered and the construction content. When accepting a construction ordering instruction, the construction ordering unit 16 may present information necessary for ordering to the user. For example, the contents of the construction contract, such as the contractor, construction location, construction date and time, construction content, and contract terms, are presented to the user for confirmation. At least a portion of the presented content, for example, the contract terms, is determined based on the contractor data entered by the contractor. The ordering process is executed, for example, by sending the order information to the contractor terminal 40. As a variant, the construction ordering unit 16 may execute the construction ordering process, for example, conditional on receiving an ordering instruction from both the user and the contractor, i.e., inputting an ordering instruction from the user and consenting to the order from the contractor. In this way, the ordering process is executed conditional on agreement between the user and the contractor.

[0030] The assistance system 10 may provide a means for enabling communication between the user and the selected contractor between the time when the assistance system 10 receives the selection of the contractor from the user and the time when the assistance system 10 receives the order instruction. For example, the assistance system 10 provides an interface that enables at least one of message transmission / reception, file transmission / reception, email, chat, and voice communication between the user terminal 30 and the contractor terminal 40 of the selected contractor. For example, the assistance system 10 may be provided with a communication tool that enables communication between the user and the selected contractor. Alternatively, the assistance system 10 may provide the user with information that enables the user to contact the selected contractor.

[0031] The material delivery ordering unit 17 performs at least one of ordering material in response to an order instruction from a user and requesting the delivery of a sample of material in response to a sample delivery instruction from a user. The material delivery ordering unit 17 receives a material ordering instruction or a material sample delivery request instruction from a user via the user terminal 30. The ordering instruction or sample delivery request instruction includes, for example, information specifying the material and the amount of material to be ordered or the sample delivery request requested. The ordering process is performed, for example, by sending order data to the material supplier system 50. The sample delivery request process is performed, for example, by sending sample delivery request data to the material supplier system 50.

[0032] The construction ordering unit 16 and the material delivery ordering unit 17 may cooperate with each other. For example, the construction ordering unit 16 and the material delivery ordering unit 17 may execute the ordering process for the construction of renovations and the ordering process for the materials for renovations, on the condition that both construction ordering instructions and material ordering instructions are input by the user. In this case, if the user has input either a construction ordering instruction or a material ordering instruction for a single renovation, but not the other, the ordering process for one of them is put on hold, and after the other ordering instruction is received, the ordering process for both of them is executed. This makes it possible to avoid missing out on ordering either the construction or the materials.

[0033] The material delivery and ordering unit 17 may execute the material ordering process on the condition that both the user and the contractor provide an order for construction. By requiring mutual agreement in this way, the user can order the materials of their choice after receiving advice from the professional remodeling contractor. On the other hand, if the material ordering process is conditional on the user's order, the user can proactively participate in the material selection process. The support system 10 may also issue an alert to the user or the contractor to prompt them to place an order if, under specified conditions, there is no material or construction ordering instruction from either the user or the contractor, or both. The specified condition for the alert notification may be, for example, the elapse of a specified period of time since the user or the contractor provided an order for construction or materials. The alert condition may be user-configurable or automatically configured. For example, the user may be able to set or adjust the time elapsed between the order instruction and the alert notification, or it may vary depending on various conditions, such as seasonal factors.

[0034] As an example, the construction ordering unit 16 presents the user with an estimated construction cost before receiving an instruction to order the construction from the user. The estimated construction cost does not include the cost of materials. The material delivery ordering unit 17 may present the user with an estimated material cost before receiving an instruction to order materials from the user. The estimated material cost does not include the cost of construction. In this way, the construction ordering unit 16 and the material delivery ordering unit 17 order materials and construction separately on the same platform. The support system 10 can present the user with separate estimated construction and material costs before the user inputs an instruction to order the construction and materials. This makes the prices of materials and construction clear to the user. As a result, the user's sense of security regarding the appropriateness of the renovation price can be improved.

[0035] (Specific example of material selection receiving unit 11) The material selection receiving unit 11 presents to the user information on materials indicated by the renovation material data stored in the storage unit 20. For example, the material selection receiving unit 11 displays the material information on the user terminal 30. The material data is supplied by the material supplier system 50. The material information presented to the user includes, for example, information identifying the material, such as product number and name, and information indicating the material's characteristics, such as performance, function, appearance image, and price.

[0036] The material selection receiving unit 11 receives a material selection from a user. For example, information on a plurality of materials that can be selected is displayed on the user terminal 30. The material selected by the user is stored in the storage unit 20 as selected material data.

[0037] 1, the material selection receiving unit 11 includes an image acquiring unit 111, a material region recognizing unit 112, and a sample image display unit 113. The image acquiring unit 111 acquires an image of a renovation location where a user desires to renovate. For example, the image acquiring unit 111 acquires a photographed image of the renovation location via the user terminal 30.

[0038] The material area recognition unit 112 recognizes a material placement area in the renovation location image where renovation materials are placed. The material placement area to be recognized may be, for example, at least one of the floor, ceiling, wall, and fixtures. Furthermore, by limiting the material placement area to be recognized to the placement areas of interior materials such as the floor, ceiling, and wall, recognition accuracy can be improved. The recognition process may be, for example, a pattern recognition process or a process using a trained model constructed by deep learning using a neural network. Processing using a trained model not only enables rapid processing without requiring human labor, but may also enable recognition with a precision beyond human imagination, providing stronger support to the user. Furthermore, the recognition process may accept a user's designation of a material area in the image, and the area designated by the user may be determined as the material placement area. Furthermore, the recognition process may recognize the direction of the material placement surface in the material placement area. In this case, for example, the direction of the material placement surface, for example, the normal direction of the material placement surface, can be determined based on the direction of the contour line of the material placement area. Furthermore, the type of material to be placed in the recognized material placement area may be determined, such as flooring, wall covering, or fittings. As another example, the type of interior material to be placed in the material placement area, such as baseboard, frame, or molding, may be determined. The type of material in the material placement area may be determined based on, for example, the position and shape of the material placement area in the image, or a designated input from the user. By being able to determine the type of material in the material placement area based on a designated input from the user in this way, it is possible to further reflect the user's wishes, thereby increasing user convenience.

[0039] The sample image display unit 113 generates a sample image in which an image of a material specified by the user is superimposed on the material placement area of ​​the renovation location image, and displays it on the user terminal 30. As an example, the sample image display unit 113 receives a designation of a material placement area in the renovation location image and a designation of a material from the user via the user terminal 30. In this case, the image of the specified material is deformed to fit the shape of the specified material placement area and superimposed on the material placement area. The image of the material is supplied in advance from the material supplier system 50 and stored in the memory unit 20.

[0040] The image acquisition unit 111, the material area recognition unit 112, and the sample image display unit 113 execute a spatial simulation of the renovation location. This spatial simulation may use, for example, AI and augmented reality technology. The spatial simulation allows the user to combine a photo of their room with the materials they are considering installing, allowing them to check the installation image in advance. This makes it easier to select materials such as flooring and wall coverings that suit their room.

[0041] The material selection receiving unit 11 may receive a material selection by a user's selection operation for the material displayed as a sample image. For example, if the user likes an ingredient in a sample image, the user can select the image by pressing the Add to Favorites button, thereby reflecting the user's preference.

[0042] The material selection receiving unit 11 can determine materials to present to the user based on information input by the user. In this case, the material selection receiving unit 11 receives input of material conditions related to materials from the user. The material conditions include, for example, at least one of the following: characteristics of the renovation location, such as the intended use, the purpose of the renovation, preferred color or design, or desired characteristics or functions of the material. The material selection receiving unit 11 extracts information about materials that meet the material conditions from the material data and displays it on the user terminal 30. This enables, for example, recommendation or narrowing down of materials according to user-specified conditions, such as the intended use of the construction space. As a result, the user can select materials that are more convincing to the user. For example, the material selection receiving unit 11 can receive input of material conditions related to interior materials and extract and present interior materials that meet the material conditions. In particular, if the materials are interior materials, the structure, such as the room layout, does not change, making it easier for the user to imagine the current room and select interior materials that are suitable for that room.

[0043] The material selection receiving unit 11 can also determine the amount of material selected by the user based on information input by the user and present it to the user. For example, the material selection receiving unit 11 receives input from the user via the user terminal 30 of information indicating the size of the renovation area. The material selection receiving unit 11 calculates the required quantity of material based on the size of the renovation area and presents it to the user via the user terminal 30. For example, if the material is flooring, the user can receive input from the user of information indicating the area of ​​the floor to be renovated. The information indicating the floor area may be the area value itself, or a value indicating the number of tatami mats or other dimensions of the room. If the floor area is a sheet material, the required length, for example, in meters, is presented to the user. If the floor material is tile, the required number of tiles is presented to the user. The material selection receiving unit 11 can also receive information indicating the size of the location where the interior materials will be placed, determine the amount of interior materials selected by the user, and present it to the user. Since the interior materials are placed without making any structural changes to the renovation area, a more accurate required amount can be presented.

[0044] The material selection receiving unit 11 can present the user with an estimated price for the materials selected by the user. For example, the material selection receiving unit 11 presents the user with an estimated price for materials calculated using the amount of material calculated based on information input by the user. Alternatively, the material selection receiving unit 11 may receive input from the user of the amount of material selected in addition to the material selection. In this case, the estimated price for materials calculated based on the amount of material input by the user can be displayed to the user. By presenting the estimated price for materials in this manner, the user can be provided with an estimated price for materials only, separate from the construction cost. In this case, the user can obtain an estimated price for materials and construction from the contractor, excluding material costs. The user can select materials and a contractor after understanding the estimated prices for renovation materials and construction, respectively. The material selection receiving unit 11 can also determine and present to the user an estimated price for interior materials selected by the user. Since the interior materials are placed without requiring structural changes to the renovation site, a more accurate estimate can be presented. As a result, the user's sense of security regarding the appropriateness of the renovation price can be improved.

[0045] The support system 10 may accept a proposal for materials or material quantities from a selected builder selected by the user, and present the user with the materials or material quantities proposed by the builder. For example, when the user inputs a request for a proposal for materials or material quantities from the selected builder, the support system 10 notifies the selected builder of the request for a proposal for materials or material quantities. The proposal request includes, for example, information about the renovation input by the user. The support system 10 transmits proposed data for materials or material quantities input by the selected builder via the builder terminal 40 to the user terminal 30 in response to the proposal request.

[0046] The selected material information providing unit 15 can provide at least one of the information on the materials, the quantity of the selected materials, and the estimated cost of the selected materials presented to the user by the material selection receiving unit 11 to the selected builder selected by the user. The selected material information providing unit 15 can also receive a proposed revision of at least one of the information on the materials, the quantity of the selected materials, and the estimated cost of the selected materials presented to the user from the selected builder to which the information has been provided, and present the proposed revision to the user. The proposed revision thus adjusted is likely to match the user's wishes, which can promote alignment between the user and the builder.

[0047] (Specific example of the contractor data receiving unit 13) The builder data receiving unit 13 receives input of information about each builder from multiple builders via each builder's builder terminal 40. For example, the builder information can be received by displaying an input form including items to be entered on the builder terminal 40. The builder information input by each builder is stored in the storage unit 20 as builder data.

[0048] The information about the builder may include, for example, the builder's available areas, available work periods, available work hours, the type of work they can handle, and their profile or self-introduction. The information about the builder may also include their construction track record, estimated construction fees, business structure, payee account, or information necessary for a construction contract with the user. In this way, builders can provide the platform with information about the areas they can handle and estimated construction fees, enabling them to be matched with users in various regions. Builders can expand the variety of work they do. The construction fee may also be referred to as the contract fee or the construction fee.

[0049] The contractor data receiving unit 13 may receive input from each contractor of a price difference period indicating a period during which construction fees differ from other periods. The price difference period may be, for example, at least one of a low-season and a high-season. Alternatively, the price difference period may be a special period such as a discount campaign period. The price difference period is presented to the user by the contractor information providing unit 12. This allows the contractor to set fees on the platform according to their own convenience. For example, the contractor can set lower prices than normal during the low-season and higher prices than normal during the high-season. This allows the contractor to receive stable orders and increase profits throughout the year. On the other hand, if the user is not in a hurry to complete the renovation, they can keep the fees low by specifying the low-season. The contractor data receiving unit 13 may also receive input from the contractor of an estimated construction fee during the price difference period. This allows the user to understand the estimated construction fee for the contractor during the price difference period. The estimated construction fee may be, for example, information indicating the difference between the construction fee and other periods.

[0050] The builder data receiving unit 13 may receive input from each builder of handled material information indicating the materials that the builder can handle as builder information. The handled material information may include, for example, information indicating whether or not each builder can handle carpentry materials, which are materials that require carpentry work involving structural modifications, and interior materials that do not require carpentry work. In this case, the handled material information may include information indicating at least one of the types of carpentry materials that the builder can handle and the types of interior materials that the builder can handle. As another example, the handled material information may include information indicating whether or not each material indicated by the material data can be handled. For example, the builder may input whether or not each of multiple materials indicated by the material data can be handled. The handling ability may be input by material product number, or by material type, such as flooring, wall covering, baseboard, or fixture. The handled material information may also include information indicating the builder's handling track record. The track record may include experience using the material in actual construction, as well as training or experience in applying the material.

[0051] (Specific example of the builder information supply unit 12) The builder information supply unit 12 can extract information on builders that meet the conditions input by the user from the builder data and present it to the user. The builder information is displayed on the user terminal 30. The conditions accepted as input by the user include, for example, at least one of the time of renovation, the work content, and the location of the renovation site. The time of renovation may be specified, for example, by date and time. The location of the renovation site may be specified, for example, by area. The conditions may also include conditions related to the builder, such as gender, word-of-mouth reviews, business type, track record, case studies, and available materials. The business type may include information such as individual, general contractor, or business scale. The builder information presented to the user may be at least a portion of the builder information accepted by the builder data accepting unit 13 from each builder.

[0052] The information about each contractor presented to the user by the contractor information supply unit 12 may include the period of difference in fees for each contractor. Furthermore, in addition to the period of difference in fees for each contractor, an estimate of the construction fee during the period of difference in fees may be presented to the user. Furthermore, a general period of difference in fees may be presented to the user from the support system 10, separate from the period of difference in fees with each contractor. For example, information indicating busy periods during the year when fees are higher than other periods and slow periods during which fees are lower than other periods may be provided to the user. This information allows the user to have construction work performed at a lower fee, while allowing the contractor to receive more work during the slow periods, thereby facilitating the equalization of workloads during busy and slow periods.

[0053] The information on each builder presented to the user by the builder information supply unit 12 may include handling material information indicating the materials that each builder can handle. For example, information indicating whether each builder can handle the selected material selected by the user in the material selection receiving unit 11 may be presented to the user. This allows the user to know whether each builder can handle the selected material. Alternatively, the builder information supply unit 12 may extract and present information on builders who can handle the selected material from the material data. In other words, the conditions for extracting builders may include the ability to handle the selected material selected by the user. If the user can obtain information on the builders' handling of the selected material, it is possible to prevent mismatches between builders selected by the user and enable the user to select the desired material without error.

[0054] (Specific example of the contractor selection reception unit 14) The contractor selection receiving unit 14 receives from the user a selection of at least one contractor from among the contractors presented by the contractor information supply unit 12. For example, information on contractors satisfying the conditions extracted from the contractor data by the contractor information supply unit 12 may be displayed on the user terminal 30 in a selectable manner. The contractor selection received by the contractor selection receiving unit 14 does not necessarily represent the user's final decision on the contractor. The user's selection of a contractor may trigger the support system 10 to obtain further information on the selected contractor. For example, the user's selection of a contractor may trigger the user to be presented with detailed information on the contractor. Alternatively, the support system 10 may enable communication between the user and the contractor, conditional on the selection of a contractor. The support system 10 may, for example, display a screen for the user to contact the contractor selected by the user. The support system 10 may, for example, enable the user to use communication tools such as an input form, a message exchange application, or a voice call application to contact the selected contractor, such as to make inquiries, schedule adjustments, or request a quote. The communication tool enables communication between the user terminal 30 and the selected contractor's contractor terminal 40. By enabling communication between the user and the selected contractor on the platform, both parties can share and discuss information on material selection and construction details, allowing for a higher level of communication between the two parties.

[0055] The renovation support system 10 is composed of one or more computers. The functions of the material selection reception unit 11, the contractor information supply unit 12, the contractor data reception unit 13, the contractor selection reception unit 14, the selected material information provision unit 15, the construction ordering unit 16, and the material delivery ordering unit 17 are realized by the computer executing a program. A program that causes a computer to operate as the renovation support system 10 and a non-transitory storage medium storing the program are also included in embodiments of the present invention. The storage unit 20 is composed of one or more storage devices accessible by the renovation support system 10. The renovation support system 10 may be implemented, for example, in a server connected to the user terminal 30 and the contractor terminal 40 via a network. The renovation support system 10 may also be composed of multiple computers distributed over a network. For example, at least a portion of the processing of the material selection reception unit 11 may be executed by an application on the user terminal 30. When at least a part of the processing of the material selection receiving unit 11 is executed by an application on the user terminal 30, the material selection processing can be executed in a series of steps, which increases convenience for the user.

[0056] (Example of system operation) FIG. 2 is a sequence diagram showing an example of the operation of the support system 10 shown in FIG. 1. In the example of FIG. 2, material data is supplied from the material supplier system 50 (S1). The material data includes, for example, the product name or product number, size, type or category, function, color, and appearance image of each material. As an example of material data supply, the material database of the material supplier system 50 may be made accessible to the support system 10. The material data may be supplied from multiple material supplier systems. The material data may further include the supplier, price, etc. of each material.

[0057] The contractor data receiving unit 13 of the support system 10 receives input of contractor information from each of the multiple contractors and stores it in the storage unit 20 (S2).

[0058] When a user accesses the support system 10 (S3) and performs a predetermined operation, the material selection receiving unit 11 presents materials to the user (S4). As an example, when a user accesses the website of the support system 10 using a browser on the user terminal 30 and performs an operation to use a space simulator on the site, multiple materials included in the material data may be displayed in a selectable manner. The user can select a material by inputting a material selection screen displayed on the user terminal 30 (S5).

[0059] Before the user accesses the support system 10 and selects materials or a contractor, the support system 10 may provide the user with content related to renovation. For example, the support system 10 may provide content such as a digital catalog of renovation materials, a collection of renovation construction examples, and a simulation of what would happen if an arbitrary image specified by the user were applied to one surface of a room, such as a wall, floor, ceiling, or fixture. This can increase the user's motivation to renovate and make it easier for the user to select materials and a contractor.

[0060] FIG. 3 is a diagram showing an example of a material selection screen that accepts material selection from a user. The material selection screen is displayed, for example, on the user terminal 30. The material selection screen of FIG. 3 includes a renovation location image display area R1 and a material specification area R2. Area R1 displays a renovation location image acquired by the image acquisition unit 111. The renovation location image may be, for example, an image selected by the user from images previously stored in the storage unit 20, or an image uploaded from the user terminal 30. In the example of FIG. 3, a link L1 to a screen on which the user selects the renovation location image and a link L2 to a screen on which the user uploads the renovation location image from the user terminal 30 are provided.

[0061] The renovation location image display area R1 displays the renovation location image and icons B1 and B2 corresponding to each material placement area in the renovation location image. Icons B1 and B2 indicate the type of material, such as flooring, wall covering, and fixtures. When the user clicks on one of the icons B2 to specify it, the type indicated by that icon, for example, the flooring material, is displayed in a specifiable manner in the material specification area R2. In this example, the material specification area R2 is scrollable.

[0062] The material specification area R2 may display all materials included in the material data, or may display materials that meet user-specified conditions. The material selection screen of FIG. 3 includes a condition specification area R3 for inputting material conditions to be displayed in the material specification area R2. The condition specification area R3 may include a text input form F1 indicating material conditions and a condition selection tool P1 for selecting conditions for each preset item. The input form F1 may include, for example, keywords or product numbers as text. The condition selection tool P1 is, for example, a pull-down menu. Condition selection items include, for example, category, color, product name, price, thickness, size, function, and NEW (new product). A category further classifies a single type of material. Examples of flooring categories include tile carpet, roll carpet, vinyl floor sheet, vinyl floor tile, moisture-resistant tile carpet, and residential tile carpet. Thus, material categories may classify materials based on at least one of product structure, material, function, and use.

[0063] The material selection screen in FIG. 3 includes an area R4 for specifying multiple materials to be placed in one material placement area, and an area R5 for specifying the placement pattern of the multiple materials to be placed in one material placement area. For example, flooring materials include products that allow multiple materials to be combined and placed in one area or location. When such a product is specified in the material specification area R2, multiple placement patterns are displayed in area R5 in a selectable manner. The number of materials displayed in area R4 is determined depending on the number of materials in the placement pattern selected in area R5. The placement patterns may include, for example, at least one of checkerboard and flush placement.

[0064] In the material specification area R2, an image of a material specified by the user is displayed superimposed on the corresponding material placement area in the renovation location image display area R1. This displays a sample image. That is, when the user specifies a material placement area in the renovation location image and specifies the material to be placed in that area, the sample image display unit 113 displays an image of the specified material superimposed on the specified material placement area. The material image is superimposed after being corrected so that its orientation corresponds to the orientation of the material placement area in the renovation location image display area R1. If the user specifies a combination and placement pattern of multiple materials for one material placement area, a composite image in which images of the specified materials are arranged in the specified placement pattern is superimposed.

[0065] If the renovation location image contains multiple material placement areas, images of materials specified by the user are superimposed on each of the multiple material placement areas. In this case, a combination of multiple materials used in one renovation location is specified.

[0066] The material selection image in FIG. 3 displays a tool B3 that allows the user to select materials specified in each material placement area of ​​the renovation location image. Tool B3 is, for example, a button. When the user clicks tool B3, the materials specified in each material placement area, i.e., the materials displayed superimposed on each material placement area of ​​the renovation location image, are stored in the storage unit 20 as selected materials. When materials are specified in each of multiple material placement areas, the combination of materials specified in the multiple material placement areas is stored as the selected materials.

[0067] The material selection screen in FIG. 3 has a button B4 that allows the user to request a proposal for materials to be used in the renovation. When button B4 is clicked, a material proposal screen is displayed. FIG. 4 is a diagram showing an example of the material proposal screen. The material proposal screen in FIG. 4 includes a condition input area R6 where the user inputs material-related conditions (material conditions), a size input area R7 where the user inputs the size of the renovation location where the materials will be placed, and a proposal display area R8 that displays material proposals.

[0068] The condition input area R6 includes pull-down menus P2 to P4 as tools for accepting user specifications regarding the facility to be renovated, the type of room to be renovated, and the desired atmosphere. The size input area R7 includes a form for accepting input of values ​​related to floor and wall sizes. Note that the values ​​indicating the material conditions and the size of the renovation location accepted by the user are not limited to the examples in FIG. 4.

[0069] The proposal display area R8 displays information about materials determined based on the information entered in areas R6 and R7. The proposal display area R8, for example, includes a renovation location image display area R1 and a proposed material display area R9. Area R1 displays a sample image in which an image of the proposed materials is superimposed on the renovation location image. Area R9 displays information about the proposed materials, such as the type of material, an exterior image, product name, quantity, and price. In the example shown in FIG. 4, a combination of multiple materials is proposed. If a single renovation project includes multiple areas to be renovated, such as floors, walls, ceilings, and fixtures, the support system 10 proposes materials for each area. The areas to be renovated may be specified by the user, or may be determined based on conditions specified by the user.

[0070] The material selection receiving unit 11 determines the materials to be proposed (presented) based on the conditions input by the user. For example, correspondence data indicating proposed (presented) materials corresponding to conditions that can be specified by the user is stored in advance in the storage unit 20. The material selection receiving unit 11 can use the correspondence data to determine proposed materials corresponding to the material conditions input by the user. The correspondence data may be data indicating materials corresponding to the conditions, or may be a trained model or other program that outputs proposed materials corresponding to the input conditions. Furthermore, the correspondence data may be data indicating a combination of materials corresponding to the conditions. For example, if there are multiple parts to be determined based on the conditions input by the user, a combination of materials including materials for each of the multiple parts may be determined as the proposed materials.

[0071] In the example of FIG. 4, the proposed material display area R9 displays the quantity and price of the proposed material in addition to information identifying the proposed material. The price is, for example, an estimated cost of the material. The material selection receiving unit 11 can determine the quantity of the proposed material based on a value indicating the size of the renovation location input by the user, such as floor area or wall dimensions. The material data includes the size of each material and the price per unit amount. For example, the required quantity of the proposed material is calculated based on the size of the renovation location input by the user and the size of the proposed material in the material data. The price of the proposed material is then calculated using the calculated quantity of the proposed material and the price per unit amount in the material data.

[0072] 4 has a button as tool B3 for the user to select the displayed suggested material. When the user clicks on tool B3, the information on the suggested material displayed in suggested material display area R9 is stored in storage unit 20 as information on the selected material selected by the user.

[0073] FIG. 5 is a diagram showing an example of a selected material display screen that displays selected materials selected by a user. In the example of FIG. 5, a list of selected materials previously selected by the user is displayed. The display of one selected material includes information T1 about the selected material and a sample image G1. Information T1 includes, for example, the type of selected material, an exterior image, product name, quantity, and price. The price is the estimated cost of the material. In the example of FIG. 5, multiple combinations of materials selected by the user are associated and stored as a single selection. As a result, for example, the combination of selected materials for each part in a renovation that includes multiple parts is stored as selected material data. Note that, as in the second example of FIG. 5, the data indicating the selected materials may also include an arrangement pattern when multiple materials are arranged in one part, such as a floor, wall, or fixture.

[0074] In the example of FIG. 5, a button B5, which is an example of a tool for requesting a sample of the selected material, and a button B6, which is an example of a tool for ordering the selected material, are provided for each selected material. When the user clicks the sample request button B5, the material delivery ordering unit 17 executes a process for requesting the delivery of the selected material (see S6 and S7 in FIG. 2). In the process for requesting the delivery, the material delivery ordering unit 17 transmits, for example, to the material supplier system 50, information indicating the delivery request, information specifying the selected material and its quantity, and information indicating the delivery destination. When the user clicks the order button B6, the material delivery ordering unit 17 executes a process for ordering the selected material. In the order process, the material delivery ordering unit 17 transmits, for example, to the material supplier system 50, information indicating the order, information specifying the selected material and its quantity, and information indicating the order source (see S15 and S16 in FIG. 2). The order process may be suspended until an order for construction is placed.

[0075] In S8 of Fig. 2, the user inputs renovation information. In accordance with the input renovation information, the contractor information supply unit 12 presents the user with information on contractors that meet the conditions (S9). For example, the contractor information is displayed in a selectable manner on the user terminal 30. The user can select a contractor by inputting information into the contractor selection screen displayed on the user terminal 30 (S10).

[0076] FIG. 6 is a diagram showing an example of a contractor selection screen. The contractor selection screen in FIG. 6 includes a contractor condition input area R10 where the user can input conditions related to the contractor for the renovation, and a contractor display area R11 that displays a list of contractors. Area R10 accepts input of conditions such as the area to which the renovation location belongs, the planned date and time for the renovation, the details of the renovation work, the gender of the contractor, word-of-mouth reviews of the contractor, and the contractor's business type. The input format for these conditions is not particularly limited, but can accept input of conditions using at least one of a selection tool such as a pull-down menu or checkbox, and text input.

[0077] Area R11 displays a list of contractors who meet the conditions entered in area R10. In the example of FIG. 6, the contractor information displayed includes the contractor's name, message, location, whether the selected material can be handled, estimated cost, and off-season. The off-season is an example of a period during which fees differ. The availability of the selected material is not limited to the example of FIG. 6; for example, the number of times the contractor has handled the material selected by the user in S5 in the past may be displayed as information indicating whether the selected material can be handled. Area R11 also includes a button B7 for contacting each contractor as a tool for the user to select a contractor.

[0078] In the example of FIG. 6, when the user clicks on the button B7 for one contractor, that contractor is stored in the storage unit 20 as a selected contractor. That is, selected contractor data indicating the selected contractor selected by the user is stored. In addition, a screen for selecting, for example, a communication tool with the selected contractor to contact the selected contractor is displayed. The communication tool may be, for example, at least one of an inquiry form for the selected contractor, a quote request form, a date and time adjustment form, a voice or video communication application, and information indicating the contact information of the selected contractor. Note that the storage of the selected contractor in the storage unit 20 may be performed on the condition that the user and the contractor communicate using the communication tool.

[0079] When the user selects a contractor, the contractor terminal 40 of the selected contractor is notified of the user's selection (S11 in FIG. 2). The selected contractor also has access to selected material data indicating the materials selected by the user (S12). The selected material data provided to the selected contractor includes information identifying the user's selected materials as well as information about the renovation location where the selected materials will be placed, such as an image of the renovation location, facilities, rooms, floor area, wall dimensions, etc.

[0080] The support system 10 may also accept input of an estimated construction fee from the selected contractor. In this case, the estimated construction fee does not include the cost of materials. The support system 10 may also accept proposals regarding materials from the selected contractor. The proposals regarding materials may be, for example, materials other than the selected materials, the quantity of materials, or the estimated cost of materials. For example, the communication tool may include a function that allows the selected contractor to input at least one of an estimated cost or a proposal regarding materials. The estimated cost or proposal regarding materials input by the selected contractor is presented to the user by the support system 10.

[0081] FIG. 7 is an example of a screen displaying a list of selected contractors that the user has selected and contacted individually. In the example of FIG. 7, the scheduled work date and time, scheduled work time, construction details, and estimated construction cost for each selected contractor are displayed. The estimated cost is, for example, entered by the selected contractor contacted by the user. By communicating with the user and the contractor, the contractor can determine a more accurate construction cost estimate. Note that when the user clicks on the display area of ​​one selected contractor, more detailed information about that selected contractor may be displayed. Corresponding to each selected contractor, there is provided a button B8 for contacting the selected contractor and a button B9 for instructing the user to place an order for construction with the selected contractor. When the button B8 for contacting the selected contractor is clicked, a screen for selecting a communication tool with the selected contractor, for example, is displayed.

[0082] The user can consider and decide which contractor to place an order with by looking at the screen shown in Fig. 7. When the button B9 for instructing the user to place an order with the selected contractor is clicked, the construction ordering unit 16 executes an ordering process for placing an order with the selected contractor (S13, S14 in Fig. 2). In the ordering process, the construction ordering unit 16 may, for example, send information indicating the ordering user to the contractor terminal 40 together with information indicating the order.

[0083] In the above example, the user can select and order materials separately from the selection and order of a contractor. This allows the user to select and, if necessary, order materials and construction separately on a single platform, i.e., one-stop. This allows the user to clearly see the prices of materials and construction, thereby improving the user's sense of security regarding the appropriateness of the prices. In addition, in the above example, the price difference period for each contractor is presented to the user. This makes it easier to match the needs of, for example, a user who wants to reduce renovation costs with a contractor who wants to increase orders during the off-season.

[0084] In the above example, the user can select materials using a spatial simulation that provides a sample image with the selected materials superimposed on the image of the renovation location. The spatial simulation is linked to the request for sample delivery and ordering of materials. In other words, when using the spatial simulation, the user can request the delivery of samples or order materials for the materials displayed in the sample image. Furthermore, the spatial simulation results can be shared with the selected contractor.

[0085] The above-described renovation support system 10 can be suitably applied to interior material renovations, as an example. Interior material renovations are less expensive than large-scale renovations that involve structural changes such as equipment replacement or layout changes. The support system 10 allows users to easily carry out interior material renovations. Therefore, the support system 10 can stimulate demand for small-scale renovations such as interior material renovations, thereby contributing to the revitalization of the renovation industry.

[0086] The configuration and operation of the renovation support system 10 are not limited to the above example. For example, in the operation shown in FIG. 2, the input reception process for renovation information (S8) is executed after the material selection reception process (S5). As a variation, S5 may be executed after S8. Furthermore, the processing order of the material selection reception process (S5) and the contractor selection reception process (S10) is not limited to the example of FIG. 2. S5 may be executed after S10. As another variation, in FIG. 2, the material ordering instruction reception process (S15) may be executed before the construction order instruction reception process (S13). In this case, for example, when a material ordering instruction is received, the material ordering process is put on hold. Then, the material ordering process (S16) is executed in response to the reception of the construction order instruction (S13).

[0087] In the above example, the user orders the materials. As a variation, the support system may be configured to allow the builder to order the materials. For example, the material ordering unit may be configured to execute processing for ordering the materials selected by the user in response to an instruction from the builder to order the materials. Alternatively, the material selection receiving unit may be configured to present materials to the builder on behalf of the user and receive a material selection from the builder.

[0088] The renovation support system may provide renovation information received from a user to multiple contractors and accept applications for renovation work from the contractors. In this case, the contractor information supply unit may extract information about the contractors who have applied from the contractor data and provide the information to the user. The renovation information received from the user may include, for example, the details of the work and the desired price.

[0089] In the above example, the builders include individuals and businesses. Alternatively, the builders who provide information to the user may be limited to individual builders such as skilled workers, or the type of work the builders do may be limited to a specific type.
