(Embodiment 1)
[overview]
First, an overview of a house plan proposal system according to an embodiment will be described. Fig. 1 is a diagram showing an overview of a house plan proposal system according to an embodiment.

The housing plan proposal system 100 is a system that allows users who are planning to build a house to be provided with a housing plan that matches their preferences. As shown in FIG. 1, the housing plan proposal system 100 includes a first information terminal 10 used by the user, a second information terminal 20 used by a housing supplier, and a third information terminal 30 used by a supplier other than the housing supplier.

Specifically, a housing supplier is a house manufacturer or a construction company. Generally, a user who wants to build a house gathers information on their own, selects a housing supplier, and then concludes a contract with the selected housing supplier after determining the outline of the house plan. With this method, the details of the house plan (total construction costs, construction schedule, etc.) are decided after the contract is signed, so there is a possibility that problems will arise in which the user is unable to freely decide the house layout, for example, finding that the layout they had envisioned cannot be realized after the contract is signed.

In contrast, in the housing plan proposal system 100, the user operates the first information terminal 10 to access the website (third information terminal 30) of another business other than the housing supplier, and receives a proposal for a housing plan that has been elaborated down to the finest details without meeting the user (S11). Then, only if the user fully agrees with the proposed housing plan, does the user express an intention to enter into a contract with the other business (S12), and the other business selects (matches) a housing supplier that can realize the housing plan (S13).

The user enters into a contract with the housing supplier that can realize the housing plan only if the user agrees with both the housing plan and the selected housing supplier (S14). In other words, the housing plan proposal system 100 allows the user to enter into a contract with the desired housing supplier when the housing plan, total construction costs, and construction schedule are almost finalized, thereby preventing the occurrence of problems such as those described above.

In addition, in the housing plan proposal system 100, the user can consider and decide on a housing plan before deciding on a housing supplier, and the user's personal information, etc. is not provided to the housing supplier until the user expresses his or her intention to enter into a contract. This prevents the user from being subjected to excessive sales pressure from housing suppliers, and the user can work on considering a housing plan at his or her own pace. Meanwhile, housing suppliers can receive offers from customers (users) from other suppliers without conducting sales activities. In other words, housing suppliers can streamline their sales activities.

The other business may be, for example, a business that does not engage in the supply of housing. By having such a third-party business operate the housing plan proposal system 100, users can consider housing plans with peace of mind and can freely select a housing supply business.

[composition]
The following describes the configuration of the house plan proposal system 100. FIG.

As shown in FIG. 2, the housing plan proposal system 100 includes a first information terminal 10, a plurality of second information terminals 20, and a third information terminal 30. Note that the housing plan proposal system 100 only needs to include at least one second information terminal 20. In other words, the housing supply companies may be narrowed down to one company in advance.

The first information terminal 10 is an information terminal used by a user. The first information terminal 10 is, for example, a portable information terminal such as a smartphone or a tablet terminal, but may also be a stationary information terminal such as a personal computer. The first information terminal 10 includes an input receiving unit 11 and a display unit 12.

The input reception unit 11 receives user input (input operations). The input reception unit 11 is realized, for example, by a touch panel, but may also be realized by a mouse and keyboard, etc.

The display unit 12 displays images for proposing a home plan to the user. The display unit 12 is realized, for example, by a liquid crystal panel, but may also be realized by an organic EL (Electro Luminescence) panel.

The second information terminal 20 is an information terminal used by the housing supply company. The second information terminal 20 is, for example, a portable information terminal such as a smartphone or a tablet terminal, but may also be a stationary information terminal such as a personal computer.

The third information terminal 30 is an information terminal used by another business operator. The third information terminal 30 is, for example, a server device (cloud server). Specifically, the third information terminal 30 includes a communication unit 31, an information processing unit 32, and a storage unit 33.

The communication unit 31 is a communication circuit (communication module) that enables the third information terminal 30 to communicate with the first information terminal 10 and the second information terminal 20 via a wide area communication network 40 such as the Internet. The communication performed by the communication unit 31 may be wired communication or wireless communication. There are no particular limitations on the communication standard of the communication performed by the communication unit 31.

The information processing unit 32 processes information related to the proposed house plan. Specifically, the information processing unit 32 is realized by a microcomputer or a processor. Specifically, the information processing unit 32 includes an acquisition unit 34, a determination unit 35, and an output unit 36. The specific processing executed by these components will be described later.

The memory unit 33 is a storage device that stores various information used to propose a house plan, computer programs executed by the information processing unit 32, and the like. The memory unit 33 is realized, for example, by a HDD (Hard Disk Drive), but may also be realized by a semiconductor memory.

[House plan data]
A plurality of home plan data are stored in advance in the storage unit 33. FIG.

In the matrix shown in Figure 3, home plan data refers to a group of floor plan data for one vertical column. In other words, each of the multiple home plan data includes multiple (or one) floor plan data. The multiple home plan data have different concepts. In other words, the multiple floor plan data included in one home plan data share a common zoning concept. The zoning concept here is, for example, a concept such as "separate living room and dining/kitchen area" or "emphasis on housework flow." The horizontal columns of the matrix in Figure 3 have similar ground shapes and the same direction of the opening (such as the entrance) is located.

The zoning concept is determined based on the positional relationship between the shared spaces, which include at least one of the living room, dining room, and kitchen, and other spaces. For example, the multiple home plan data may include home plan data that emphasizes housework flow, and the multiple floor plan data included in this home plan data may all be designed so that the distance from the kitchen to the entrance is equal to or less than a predetermined value. The multiple home plan data may also include home plan data that includes multiple floor plan data in which the entrance and living room are connected by a long dirt floor.

The zoning concept may also be determined based on at least one of the location of stairs and the type of stairs. For example, multiple home plan data may include home plan data in which the location of stairs is common as a zoning concept (e.g., stairs are always provided in the living room).

Examples of types of stairs include "open stairs in the living room", "independent stairs", and "living room stairs". The multiple home plan data may include home plan data in which types of stairs are standardized as a zoning concept.

The zoning concept may also be determined based on at least one of the location of the kitchen and the type of kitchen. The above-mentioned house plan data that emphasizes household chore traffic flow can be said to have a zoning concept determined based on the location of the kitchen.

Examples of kitchen types include "I-type," "L-type," "wall-mounted/peninsula type," "II-type," and "island type." The multiple home plan data may include home plan data in which the types of kitchens are standardized as a zoning concept.

The multiple floor plan data included in one house plan data differ in at least one of the ground shape and the direction in which the opening is located (such as the direction of the front door). The house plan proposal system 100 is a system built on the idea of matching the house plan data to the land, rather than matching the house plan data to the land, and the multiple floor plan data included in one house plan data are prepared to expand the land options. Figure 4 is a diagram showing an example of applying multiple floor plan data to land. If two types of floor plan data with different ground shapes as shown in Figure 4 are prepared, it becomes easier to match the house plan data to the land. Note that the ground shape refers to the shape of the part of the house that contacts the land.

In addition, three interior patterns are prepared for each of the multiple home plan data. The user can select one of the three interior patterns for each of the multiple floor plan data included in one home plan data. Note that the interior refers to interior materials such as wallpaper, flooring, and ceiling materials, but may also include fixtures such as built-in lighting (downlights).

Each of the multiple home plan data described above was created in advance under the supervision of experts, ensuring a certain level of quality. Specifically, each of the multiple home plan data includes BIM (Building Information Modeling) data. BIM data is 3D CAD data of a building (home) that includes various attribute information such as the specifications of structural materials (dimensions, materials, price, etc.; same below), equipment specifications, specifications of interior materials, and specifications of exterior materials.

When a housing supplier builds a house for a user, the housing plan data including BIM data (such as the final housing plan data described below) is provided to the housing supplier by other businesses. By utilizing the BIM data, the housing supplier can efficiently carry out various housing applications, material procurement, process management, construction management, etc. In other words, by providing the housing supplier with housing plan data including BIM data, the housing plan proposal system 100 can support the housing supplier in efficiently carrying out various housing applications, material procurement, process management, construction management, etc.

[Example of operation]
Next, a description will be given of an example of the operation of the house plan proposal system 100. FIG.

The input reception unit 11 of the first information terminal 10 receives input of data related to the user's preferences (S21). The data input results are transmitted from the first information terminal 10 to the third information terminal 30, for example, as lifestyle needs data indicating the user's needs for the user's lifestyle, and interior preference data indicating the user's preferences for home interiors.

The acquisition unit 34 of the third information terminal 30 acquires the living needs data and the interior preference data via the communication unit 31 (S22). The determination unit 35 performs a process of determining the home plan data to be proposed to the user based on the acquired living needs data and the acquired interior preference data (S23). In the determination process, the home plan data to be proposed to the user is determined from the multiple home plan data shown in FIG. 3 above. Details of how the home plan data to be proposed to the user is determined based on the living needs data and the interior preference data will be described later.

The output unit 36 outputs proposal information for proposing the determined home plan data to the first information terminal 10 via the communication unit 31 (S24). As a result, a display screen such as that shown in FIG. 6 is displayed on the display unit 12. In other words, the contents of the proposal information are visualized. FIG. 6 is a diagram showing an example of a display screen for proposing home plan data. Note that at least one piece of home plan data needs to be proposed, and multiple pieces of home plan data may be proposed.

The user checks the contents of the proposed information visualized by the first information terminal 10. If the user finds any proposed home plan data that he or she likes and intends to enter into a contract for the construction of a house, the user inputs data to select home plan data into the first information terminal 10, and the input reception unit 11 receives this data input (S25). The data input result is transmitted from the first information terminal 10 to the third information terminal 30 as selected plan information indicating the home plan data selected by the user. Note that in step S25, the user selects not only home plan data but also an interior pattern.

The acquisition unit 34 of the third information terminal 30 acquires the selected plan information via the communication unit 31 (S26). The determination unit 35 determines the home plan data selected by the user as the final home plan data based on the acquired selected plan information (S27). After the final home plan data has been determined, the output unit 36 outputs review request information including the final home plan data to each of the multiple second information terminals 20 via the communication unit 31 (S28).

Each of the multiple second information terminals 20 receives the review request information including the final housing plan data. Each of the multiple housing supply businesses corresponding to the multiple second information terminals 20 searches for land on which to build one of the multiple houses (corresponding to the multiple floor plan data) included in the final housing plan data. Each of the multiple second information terminals 20 transmits response information to the third information terminal 30, including land data of the land found by the housing supply business based on data input by the housing supply business, and designation information that designates floor plan data whose ground shape is suitable for the land data among the multiple floor plan data included in the final housing plan data. Note that at this time, some of the multiple second information terminals 20 may not transmit response information. In other words, the multiple housing supply businesses may include housing supply businesses that do not respond to the review request information.

The acquisition unit 34 of the third information terminal 30 acquires response information (land data and specified information) from each of the multiple second information terminals 20 via the communication unit 31 (S29), and the output unit 36 outputs the acquired multiple pieces of response information (multiple sets of land data and specified information) to the first information terminal 10 via the communication unit 31 (S30).

The user checks the contents of the multiple pieces of response information (multiple sets of land data and specified information) visualized by the first information terminal 10. The contents of the response information are, in other words, combinations of land and house. If the user finds a combination of land and house that he likes and intends to enter into a contract for the construction of a house, he inputs data to select the combination of land and house into the first information terminal 10, and the input receiving unit 11 receives this data input (S31). The data input result is transmitted from the first information terminal 10 to the third information terminal 30 as selection result information indicating the response information selected by the user (sets of land data and specified information; in other words, combinations of land and house).

The acquisition unit 34 of the third information terminal 30 acquires the selection result information via the communication unit 31 (S32). The output unit 36 outputs decision notification information for notifying the decision of the business operator to build the user's house via the communication unit 31 to the second information terminal 20 that is the sender of the response information (a set of land data and specified information) selected by the user (S33).

Then, the acquisition unit 34 acquires contract information for the user and the housing supplier to enter into a contract from each of the first information terminal 10 and the second information terminal 20 (S34). For example, the acquisition unit 34 acquires personal information of the user from the first information terminal 10 at a timing after the selection result information is acquired, and the output unit 36 outputs the acquired personal information to the second information terminal 20 that is the sender of the response information selected by the user.

The contract information (such as personal information) sent from the first information terminal 10 to the third information terminal 30 may be sent together with the selection result information in step S32. It is also assumed that the contract between the user and the housing supplier may be made face-to-face without using the housing plan proposal system 100. In this case, step S34 is omitted, and only the user's personal information for the housing supplier to contact the user needs to be sent to the second information terminal 20.

As described above, the housing plan proposal system 100 outputs the final housing plan data to the second information terminal 20 of the housing supplier after the final housing plan data is determined, and does not output the housing plan data to the second information terminal 20 before the final housing plan data is determined. In other words, no information about the housing plan is exchanged between the user and the housing supplier until the final housing plan data is determined (until the layout of the house, etc. is decided). Because the exchange is non-face-to-face until the final housing plan data is determined, the user can carefully consider the housing plan until he or she is satisfied. In other words, the housing plan proposal system 100 can support the user in considering the housing plan at his or her own pace.

In the above operation example, the final home plan data included in the review request information does not have to be complete. The final home plan data will ultimately be used to build a home, but will initially be used by housing suppliers to search for land suitable for the final home plan data. Therefore, the output unit 36 may reduce the amount of information of the multiple floor plan data included in the final home plan data and output it to the second information terminal 20. The multiple floor plan data with reduced information may include at least information indicating the ground shape. This prevents details of the final home plan data from being unnecessarily known to housing suppliers and the like who will not ultimately build the home. In addition, the amount of communication (amount of information) when transmitting the review request information is reduced.

[How to determine house plan data]
Next, a method for determining the house plan data (also referred to as target house plan data) proposed to the user (details of the process of steps S21 to S23 in FIG. 5) will be described in detail. FIG. 7 is a flowchart of the method for determining the house plan data. The method for determining the interior pattern proposed to the user will be described separately.

First, the decision unit 35 provides a question to the user by displaying a display screen such as that shown in FIG. 8 on the first information terminal 10 (S41). FIG. 8 is a diagram showing an example of a display screen for providing a question to the user. By sequentially displaying display screens such as that shown in FIG. 8, a plurality of questions are provided to the user. As shown in FIG. 8, the question, for example, asks the user about his/her lifestyle, and the answer indicates the extent to which the user agrees with the lifestyle asked about on a multiple-level scale (e.g., on a five-level scale).

The acquisition unit 34 acquires the answer data entered by the user in the input receiving unit 11 to the multiple questions as living needs data (S42).

A needs calculation coefficient is set for each of the multiple questions provided to the user. FIG. 9 is a diagram showing an example of the needs calculation coefficient. The needs calculation coefficient is set for each of multiple lifestyle needs items, and the value varies depending on how the user answers the questions. Note that the needs calculation coefficient may be set taking into account the order in which the questions are provided (the order in which the questions are displayed).

Based on the living needs data (response data), the determination unit 35 sums the needs calculation coefficients for each of the multiple living needs items, and calculates the importance of the living needs by adding an initial needs value (not shown) determined for each living needs item to the summed needs calculation coefficient (S43).

The determination unit 35 then normalizes each of the calculated degrees of importance to a value between 0 and 1 (S44). For example, if the degree of importance of a certain lifestyle need item can be a maximum value Nmax or a minimum value Nmax depending on the user's response, and the actual degree of importance obtained in step S43 is Nsum, the normalized lifestyle need score Nnorm is Nnorm = (Nsum - Nmin) / (Nmax - Nmin).

Next, the determination unit 35 extracts a predetermined number (e.g., five) of items in order of the calculated importance after normalization, starting with the one with the greatest importance (S45).

Here, for each of the multiple home plan data, a degree of fulfillment is set for each of the multiple lifestyle needs items. FIG. 10 is a diagram showing an example of the degree of fulfillment. The determination unit 35 calculates the degree of conformity of each of the k home plan data based on the five degrees of importance extracted in step S45 and the five degrees of fulfillment corresponding to these five degrees of importance (S46). For example, if the five degrees of importance extracted in step S45 are Ni (i = 1, 2, 3, 4, 5), and the five degrees of fulfillment corresponding to the five degrees of importance in each of the k home plan data are NFki (i = 1, 2, 3, 4, 5), the degree of conformity of the kth home plan is calculated based on the formula Mk = 1 - √ {(N1 - NFk1) ^ 2 + (N2 - NFk2) ^ 2 + ... + (N5 - NFk5) ^ 2}.

Then, the determination unit 35 determines a predetermined number of home plan data in descending order of suitability as home plan data to be proposed to the user (S47). The determined home plan data is proposed to the user, for example, by displaying a display screen such as that shown in FIG. 6 on the display unit 12 of the first information terminal 10.

In this way, the home plan proposal system 100 can determine the home plan data to be proposed to the user based on the living needs data.

[How to determine the interior pattern]
Next, a method for determining an interior pattern (also referred to as a target interior pattern) to be proposed to a user will be described in detail. Fig. 11 is a flowchart of the method for determining an interior pattern. In the following description, it is assumed that eight types of interior patterns, interior patterns (1) to (8), are prepared.

First, the decision unit 35 presents the user with a multiple-choice question by displaying a display screen such as that shown in FIG. 12 on the first information terminal 10 (S51). FIG. 12 is a diagram showing an example of a display screen for presenting the user with a multiple-choice question. As shown in FIG. 12, the multiple-choice question is a question that requests the user to select one of two interior images.

By sequentially displaying display screens such as those shown in FIG. 12, the user is presented with multiple multiple-choice questions. The acquisition unit 34 acquires the answer data entered by the user in the input reception unit 11 to the multiple questions as interior preference data (S52).

The determination unit 35 determines the interior preference type of the user based on the acquired interior preference data (S53). The determination unit 35 determines whether the user's interior preference type is one of interior preference types A to E, for example, by repeatedly presenting questions and acquiring answers based on the judgment tree of FIG. 13. FIG. 13 is a diagram showing an example of a judgment tree for interior preference types. Note that the total number of interior preference types is five, which is different from the total number of interior patterns (eight) and the number of interior patterns selectable in one piece of home plan data (three).

Here, two types of interior preference scores (e.g., two types of affective evaluation values) are associated with the interior preference types A to E, and each of the interior preference types A to E can be expressed as a point plotted in a two-dimensional coordinate space having two axes indicating the two types of interior preference scores (in other words, a two-dimensional vector). Similarly, two types of interior preference scores are associated with the interior patterns (1) to (8), and each of the interior patterns (1) to (8) can be expressed as a point plotted in the same two-dimensional coordinate space as the interior preference types A to E (in other words, a two-dimensional vector). Figure 14 is a diagram showing a two-dimensional coordinate space in which the points indicating the interior preference types A to E (white squares) and the points indicating the interior patterns (1) to (8) (black circles) are plotted. In the example of Figure 14, the points indicating the interior preference type C and the points indicating the interior pattern (3) overlap.

The determination unit 35 determines an interior pattern to be suggested to the user based on the interior preference type determined in step S53 (S54). Specifically, the determination unit 35 determines, from among the three interior patterns selectable in the house plan data determined in step S47, the interior pattern that is closest to the interior preference type determined in step S53 in the coordinate space of FIG. 14 as the interior pattern to be suggested to the user. In other words, the determination unit 35 determines, as the interior pattern to be suggested to the user, the interior pattern whose interior preference score is most similar to the interior preference type determined in step S53.

The determined interior pattern is proposed to the user, for example, by displaying a display screen such as that shown in FIG. 15 on the display unit 12 of the first information terminal 10. FIG. 15 is a diagram showing an example of a display screen for proposing an interior pattern. Such a display screen is displayed based on the proposal information output from the third information terminal 30 to the first information terminal 10.

The proposed information output from the third information terminal 30 to the first information terminal 10 includes not only information indicating the interior pattern, but also information indicating the exterior design. The exterior design is determined, for example, according to the determined interior pattern. In other words, when the interior pattern is determined to be one of the interior patterns (1) to (8), the exterior design is automatically determined in conjunction with this.

The determined interior pattern is proposed to the user, for example, by displaying a display screen such as that shown in FIG. 16 on the display unit 12 of the first information terminal 10. FIG. 16 is a diagram showing an example of a display screen for proposing an exterior design.

In this way, the home plan proposal system 100 can determine the interior pattern and exterior design to be proposed to the user based on the interior needs data.

The exterior design may be determined independently of the interior pattern. For example, the exterior design may be determined based on exterior design needs data obtained as a result of providing a multiple-choice question that requests the user to select one of two exterior design images.

[Modification 1]
In the embodiment, matching of the floor plan data included in the final house plan data with the land data (i.e., matching of the house with the land) is performed by the housing supplier, but it may be performed by another business. In other words, it is also possible that the land search is performed by another business rather than the housing supplier. In this case, the user selects a desired housing supplier from among multiple housing suppliers, taking into consideration information such as the total cost of construction and the construction schedule.

[Modification 2]
In the embodiment, one degree of satisfaction for each of the plurality of living needs items is set for the house plan data, but when the house plan data includes a plurality of floor plan data, the degree of satisfaction for each of the plurality of living needs items may be set to a different value for each floor plan data in the same house plan data. In this case, one of the plurality of floor plan data of the house plan data is set as a representative value, and the degree of satisfaction for each of the plurality of living needs items of the house plan data is set as a representative value. It is preferable to set the representative value by selecting the one having the same ground shape and the same direction in which the opening is located (the same horizontal column of the matrix).

[Effects, etc.]
As described above, the house plan proposal system 100 is a house plan proposal system for a business other than a housing supply business to propose a house to a user via the first information terminal 10. The house plan proposal system 100 includes an acquisition unit 34 that acquires, from the first information terminal 10 used by the user, life needs data indicating the needs of the user for the life and interior preference data indicating the user's preference for the interior of the house, a storage unit 33 that stores a plurality of house plan data, each of which includes one or more floor plan data, for each of which a plurality of interior patterns can be selected, a determination unit 35 that determines target house plan data from the plurality of house plan data based on the acquired life needs data, and determines a target interior pattern from a plurality of interior patterns selectable in the determined target house plan data based on the acquired interior preference data, and an output unit 36 that outputs proposal information for proposing the determined target house plan data and the determined target interior pattern to the first information terminal 10.

According to this type of home plan proposal system 100, the user can consider home plans at their own pace without being subjected to excessive sales pressure from housing supply businesses by receiving home plan proposals from other businesses in a third-party position. In other words, the home plan proposal system 100 can support the user in considering home plans at their own pace. Furthermore, according to the home plan proposal system 100, the user can select multiple interior patterns for one home plan data.

For example, the proposal information further includes information indicating an exterior design that is determined according to the determined target interior pattern.

With this type of housing plan proposal system 100, users can receive proposals for exterior designs.

For example, the interior preference data may indicate the user's responses to a number of questions, each of which requests the user to select one of two interior images.

According to this type of home plan proposal system 100, a user can receive proposals for interior patterns by answering a number of questions.

For example, the determination unit 35 determines the user's interior preference type from among multiple interior preference types based on the acquired interior preference data, and determines a target interior pattern based on the determined interior preference type.

Such a home plan proposal system 100 can propose an interior pattern suitable for a user based on which of multiple predefined interior preference types the user falls into.

Furthermore, for example, each of the multiple interior preference types is represented as a point plotted in a two-dimensional coordinate space having two axes indicating the two types of interior preference scores by being associated with two types of interior preference scores. Each of the multiple interior patterns is represented as a point plotted in the two-dimensional coordinate space by being associated with two types of interior preference scores. The determination unit 35 determines, from among the multiple interior patterns, the interior pattern that is closest to the determined interior preference type in the two-dimensional coordinate space as the target interior pattern.

Such a home plan proposal system 100 can propose an interior pattern suitable for a user based on which of multiple predefined interior preference types the user falls into.

The house plan proposal method executed by a computer such as the house plan proposal system 100 is a house plan proposal method for a business other than a housing supply business to make proposals regarding the construction of a house to a user via a first information terminal 10. The house plan proposal method includes an acquisition step S22 (S42, S52) of acquiring, from the first information terminal 10 used by the user, lifestyle needs data indicating the user's lifestyle needs and interior preference data indicating the user's preferences for the interior of the house, a first determination step S47 of determining target house plan data from a plurality of house plan data each including one or more floor plan data, each of which has a plurality of selectable interior patterns, based on the acquired lifestyle needs data, a second determination step S54 of determining a target interior pattern from a plurality of selectable interior patterns in the determined target house plan data, based on the acquired interior preference data, and an output step S24 of outputting proposal information for proposing the determined target house plan data and the determined target interior pattern to the first information terminal 10.

According to this type of home plan proposal method, by receiving home plan proposals from other businesses acting as third parties, the user can consider home plans at his or her own pace without being subjected to excessive sales pressure from housing supply businesses. In other words, the home plan proposal method can support the user in considering home plans at his or her own pace. Furthermore, according to the home plan proposal method, the user can select multiple interior patterns for one home plan data.
