Description

The present invention relates to a renovation information proposal device and a renovation information proposal system.

Traditionally, when renovating or building a home, sales representatives from home builders and construction companies would listen to the requests of the customer and their family, and then propose a home plan from a collection of pre-prepared home plans that was closest to the customer's ideal image. However, it was extremely difficult for sales representatives from home builders and construction companies to listen to the customer's requests, visualize the customer's home, and accurately convey these customer requests to the architect.
Patent Literature 1 discloses a technology related to a web service that uses keywords associated with questions to be answered by customers to extract a home plan that matches a customer's ideals from among a large number of home plans. This technology allows the process of accurately extracting customer needs without relying on the skills of sales representatives at home builders or construction companies, and quickly proposing a specific home plan to the customer.

Japanese Patent Application Laid-Open No. 2008-242923

However, when renovating a home, unlike building a new one, it is difficult to reflect one's wishes throughout the entire house. Therefore, whether one communicates one's wishes and concerns to the sales representative of a home builder or construction company, or uses a traditional online service, it is important to grasp the key points of one's wishes and concerns.
However, not all customers have a clear vision of how they should renovate their homes, and many customers only have a vague understanding of their own desires and ideal lifestyles, or may not even be aware of what their desires or ideal lifestyles are.When trying to elicit the desires of such customers, asking highly specific questions from the early stages can lead to the customer being distracted by those questions, and in the end, it can be difficult to discover their true intentions.

The present invention was made in light of the above circumstances, and its objective is to be able to understand the customer's true intentions as closely as possible and propose information on specific renovation methods necessary to realize the customer's ideal lifestyle.

The invention described in claim 1 is a renovation information suggestion device 1 that derives home renovation information desired by a customer U1 by having the customer U1 select a theme in hierarchical order from a plurality of themes that are hierarchically classified, for example, as shown in FIGS. 1 to 11,
a first theme storage means for storing a first main theme asking about an ideal way of living in a house and a plurality of first sub-themes positioned at a lower level of the first main theme;
a question storage means for storing questions belonging to each theme located at a lower level of the first main theme;
A renovation information storage means for storing a plurality of pieces of renovation information associated with the plurality of first minor themes;

More specifically, as shown in Figures 3 to 6, the questions for customer U1 include, at the highest level (concept), a first main theme asking about the ideal way of living in a home and a second main theme asking about concerns about the home. In other words, there are two major themes that form the foundation of the questions. Each main theme then encompasses multiple subthemes located at lower levels (sub-concepts). The multiple themes, each consisting of two main themes and multiple subthemes belonging to each main theme, are structured as questions and multiple-choice answers. Customer U1 can automatically select a theme by answering the questions in hierarchical order. The remodeling information desired by customer U1 can then be derived from the final answer selected through the theme selection process. In other words, by simply answering the questions, customer U1 selects multiple hierarchically categorized themes, thereby obtaining remodeling information.

Several themes will be explained in more detail.
Of the two main themes at the highest level, the first main theme, as mentioned above, asks about the ideal way of living in a home. In other words, it asks about how people spend their time in their homes and their lifestyles.

In this embodiment, the minor theme XVI (A3p) is a response to a question (Q3f) belonging to the medium theme, and specifically, the content is "Relaxing Bath Life."
The renovation information associated with this minor theme proposes "renovation of the bathroom area." In other words, the renovation information is proposed to adapt the bathroom and surrounding area of the home to suit the preferences of customer U1 and to make it more user-friendly.

On the other hand, the second main theme (Q4) in this embodiment is specifically a question asking, "What are your concerns about your home?" as shown in FIG. 6. There are multiple second sub-themes at a lower level than this second main theme. Each of the multiple second sub-themes is associated with renovation information. Customer U1 selects one of the second sub-themes as an answer to the question in the second main theme.
In this embodiment, there are four second minor themes, which, for convenience of explanation, are referred to as second minor theme I, second minor theme II, second minor theme III, and second minor theme IV.

The second minor theme I (A4a) in this embodiment is specifically an answer to the second major theme, which is "the heat in summer and the cold in winter."

There is no renovation information associated with this second sub-theme. In other words, customer U1 has no concerns about the home he owns or lives in, and therefore there is no renovation information to suggest to customer U1.

The above-described multiple themes are stored in the storage unit 1b of the renovation information proposal device 1 as data necessary for generating a screen on which the multiple themes are displayed.
That is, the memory unit 1b functions as the first theme storage means, question storage means, and second theme storage means. In short, the memory unit 1b stores a first main theme and a plurality of first sub-themes (major category themes, medium category themes, small category themes), questions belonging to the major category themes and questions belonging to the medium category themes, a second main theme, and a plurality of second sub-themes.
The number and content of the multiple themes and questions are not limited to those described above and may be changed as appropriate without departing from the spirit of the present invention. For example, the multiple themes may include a care-related theme or a barrier-free theme.

The above-mentioned multiple themes are then displayed as web pages on the output unit 1e (for example, a display device such as a display) of the renovation information proposal device 1 or on the display units of the first information terminal 3 and the second information terminal 4.
Here, the theme output program is a program for extracting and outputting multiple themes stored in the storage unit 1b in hierarchical order, and is executed by the control unit 1a when multiple themes are to be displayed on the output unit 1e or the display units of the information terminals 3 and 4. In other words, the theme output program, when executed by the control unit 1a, causes the computer of the renovation information proposal device 1 to function as theme output means.
Furthermore, when customer U1 selects a theme, the selection operation is performed by the input unit 1d in the case of the renovation information proposal device 1, and by the operation unit in the case of the information terminals 3 and 4. Furthermore, when multiple themes are to be displayed on the display units of the information terminals 3 and 4, data is exchanged through the communication unit 1c of the renovation information proposal device 1.

In this embodiment, when the theme output program is executed by the control unit 1a, it first displays the second main theme and multiple second sub-themes, and after customer U1 has completed theme selection of the second sub-theme, it is configured to display the first main theme and multiple first sub-themes in hierarchical order according to the theme selection by customer U1.
However, the order of displaying the second main theme and the multiple second sub-themes and the first main theme and the multiple first sub-themes may be reversed. That is, the first main theme and the multiple first sub-themes may be displayed, and after the customer U1 has completed theme selection of the first sub-theme, the second main theme and the multiple second sub-themes may be displayed.

To explain in more detail, in this embodiment, as shown in Figure 7, first, a second main theme is displayed as question 1, and then multiple second sub-themes are displayed as answers to the question on this second main theme.
Customer U1 selects a second sub-theme that best suits his or her needs from among multiple second sub-themes. The selected second sub-theme is recognized as an attribute for deriving renovation information that suits customer U1 from among the many pieces of renovation information. In other words, when customer U1 selects a second sub-theme, renovation information that has the attributes of that second sub-theme is extracted from among the many pieces of renovation information.

Next, a first main theme as question 2 is displayed, and a plurality of large classification themes as answers to the question of this first main theme are displayed.
Customer U1 selects a major category theme that best suits his or her needs from among multiple major categories. The selected major category theme is recognized as an attribute for deriving renovation information that suits customer U1 from among the many pieces of renovation information. In other words, when customer U1 selects a major category theme, renovation information that has the attributes of that major category theme is extracted from the many pieces of renovation information.

When a major theme is selected, a question belonging to the major theme is displayed as Question 3, and a plurality of intermediate themes are displayed as answers to the question belonging to this major theme.
Customer U1 selects a theme that best suits his or her needs from among multiple themes. The selected theme is recognized as an attribute for deriving renovation information that suits customer U1 from a large amount of renovation information. In other words, when customer U1 selects a theme, renovation information with the attributes of that theme is extracted from the large amount of renovation information.

When a middle category theme is selected, a question belonging to the middle category theme is displayed as Question 4, and a plurality of small category themes are displayed as answers to the question belonging to this middle category theme.
Customer U1 selects a subcategory theme that best suits his or her needs from among multiple subcategory themes. The selected subcategory theme is recognized as an attribute for deriving renovation information that suits customer U1 from among the many pieces of renovation information. In other words, when customer U1 selects a subcategory theme, renovation information that has the attributes of that subcategory theme is extracted from the many pieces of renovation information.

Note that questions 3 and 4 in the screen display in Figure 7 are changed as appropriate depending on the theme selected by customer U1. Also, the display order of the first main theme (questions 2-4) and the second main theme (question 1) may be reversed, as described above.

When a subcategory theme is selected in question 4, a screen 10 (web page) showing renovation information to be proposed to customer U1, such as that shown in Figure 8, is displayed on the output unit 1e (e.g., a display device such as a monitor) of the renovation information proposal device 1 or on the display unit of the first information terminal 3 or second information terminal 4.

Even if customer U1 selects multiple themes in hierarchical order, if the number of renovation information extracted is large, it may be possible to further narrow down the results. That is, without clearing the attributes selected in the first theme selection, a second theme selection is performed to increase the number of selected attributes (see Figure 8, etc.). This reduces the number of renovation information extracted, allowing for narrowing down the results to reflect customer U1's wishes, making it possible to propose appropriate renovation information to customer U1.

When the renovation information to be proposed to customer U1 is displayed on the output unit 1e of the renovation information proposal device 1 or on the display unit of the first information terminal 3 or the second information terminal 4, the control unit 1a executes the above-mentioned renovation information output program.
The renovation information output program is a program for extracting and outputting renovation information associated with the first sub-theme and/or second sub-theme selected by customer U1 from the renovation information database 2. In other words, the renovation information output program, when executed by the control unit 1a, causes the computer of the renovation information proposal device 1 to function as renovation information output means.

The upper part of the screen 10 displayed when the renovation information output program is executed is a renovation information display field 11 for displaying renovation information. A plurality of tabs are provided at the top of the screen 10.
The multiple tabs include a technical information tab 11a labeled "Technical Information," an image information tab 11b labeled "Image Information," a floor plan information tab 11c labeled "Floor Plan Information," and an exhibition hall information tab 11d labeled "Exhibition Hall Information," and by selecting a tab, the information displayed in the renovation information display area 11 can be switched.
8 shows a screen that is displayed when the image information tab 11b is selected, and FIG. 10 shows a screen that is displayed when the floor plan information tab 11c is selected.

The lower part of the screen 10 is a theme display field 12 for displaying the theme selected by the customer U1. The theme display field 12 has a problem countermeasure attribute display field 12a, a major category attribute display field 12b, a medium category attribute display field 12c, and a minor category attribute display field 12d.
The problem countermeasure attribute display field 12a displays which second sub-theme has been selected from among a plurality of second sub-themes included in the second main theme.
The major category attribute display field 12b displays which major category theme has been selected from among a plurality of first minor themes included in the first main theme.
The intermediate category attribute display field 12c displays which intermediate category theme has been selected from among a plurality of first sub-themes included in the first main theme.
The minor category attribute display field 12d displays which minor category theme has been selected from among a plurality of first minor themes included in the first main theme.
The theme display field 12 may be set to be hidden, or may not be displayed on the screen 10 at all.

When the image information tab 11b is selected, the screen 10 displays an appealing point explanation section 13 that displays text about the appealing points of the renovation information displayed in the renovation information display area 11. In this embodiment, an extension line extends from the proposed renovation area (the kitchen counter and flooring in Figure 8), and the extension line leads to the appealing point explanation section 13, where the appealing points of the renovation information are displayed in text. If one renovation information item has multiple appealing points, multiple appealing point explanation sections 13 may be displayed, as shown in Figure 8.

The appealing point explanation section 13 is linked to a detailed comment section 14 as shown in FIG. 9, which explains the appealing points in more detail.
The detailed comment section 14 can be displayed, for example, by hovering the mouse over the appealing point explanation section 13 or by tapping on the appealing point explanation section 13 .
In addition, the detailed comment section 14 may be displayed not only by hovering the mouse over or tapping the appealing point explanation section 13, but also by hovering the mouse over or tapping the proposed renovation section in the renovation information display section 11.
In addition, the detailed comment field 14 in this embodiment is displayed as a speech bubble.

Renovation information may include information about facilities and equipment to be installed in the home, such as the system kitchen shown in Figures 8 and 9. The detailed comment field 14 may also include an image display field 14a that displays images of such facilities and equipment from different angles, or images showing their functions.

The image display field 14a also has an AR activation button 14b set therein. The AR activation button 14b functions when the terminal displaying the screen 10 is a mobile information terminal such as a smartphone having a camera function.
To explain in more detail, first, AR (Augmented Reality) is a technology that displays a virtual world superimposed on a real-world scene, and is also called augmented reality.
The information terminal 3 used by the customer U1 and the information terminal 4 used by the person in charge U2 are smartphones with camera functions. In this embodiment, the information terminals 3 and 4 are equipped with augmented reality (AR) means for displaying images of the facilities and equipment installed in the home, superimposed on the interior scenery of the home. An AR program is stored in the memory of the information terminals 3 and 4, and the AR program is executed by a control unit, such as a CPU, in the information terminals 3 and 4, causing the computers of the information terminals 3 and 4 to function as AR means.
The augmented reality means in the information terminals 3 and 4 can be started by tapping the AR activation button 14b in the image display field 14a displayed on the display unit, which is a touch panel.

In the example shown in Figure 9, when the AR activation button 14b displayed in the image display field 14a is tapped, the scenery inside the house is displayed on the display unit of the information terminal 3, 4, and an image of the system kitchen is superimposed on it.
The system kitchen, which is displayed superimposed on the interior of the home, can be temporarily fixed (temporarily installed) within the interior of the home shown on the display unit. In addition, the screen on which the system kitchen is superimposed can be captured and saved as a screenshot.

10 shows the screen 10 when the floor plan information tab 11c is selected, and the renovation information display field 11 displays the floor plan information of the house when the renovation information associated with the first sub-theme and/or the second sub-theme selected by the customer U1 is adopted. If the house is a multi-story house, the floor plan information may be displayed for each floor.
In the case of floor plan information, an appealing point explanation section 13 and a detailed comment section 14 as shown in FIGS. 8 and 9 may also be displayed.

Although not shown in the figure, when the technical information tab 11a is selected, the renovation information display field 11 displays information about the technology used in the renovation information associated with the first sub-theme and/or second sub-theme selected by customer U1.

Furthermore, when the exhibition hall information tab 11d is selected, the renovation information display field 11 displays information about the exhibition hall where customers can actually see renovation examples of the renovation information associated with the first sub-theme and/or second sub-theme selected by customer U1.

In addition, renovation information is basically stored in advance in the renovation information database 2, but it may also be possible to obtain it from an external information server 5 that has renovation information that is not stored in the renovation information database 2.
That is, as shown in FIG. 1, the renovation information proposal device 1 is communicably connected to an external information server 5, and can obtain renovation information that is not in the renovation information database 2 from the external information server 5.

1, the renovation information proposal device 1 is communicably connected to another system server 6, which is an external device constituting another system. The renovation information proposal device 1 uses a renovation information output means to output renovation information associated with the first sub-theme and/or second sub-theme selected by customer U1, and transmits the output to the other system server 6. The renovation information proposal device 1 may also obtain information from the other system server 6 that can contribute to proposing renovation information.
In other words, data can be sent and received between the renovation information proposal system including the renovation information proposal device 1 and other systems including other system servers 6, and these systems can be linked together.

The other system server 6 is managed, for example, by the company, organization, or group to which the person in charge U2 belongs. In other words, since both the renovation information proposal device 1 and the other system server 6 are managed by the company, organization, or group to which the person in charge U2 belongs, they can easily be linked to each other.

The other system is a system that aims to diagnose various attitudes and ways of thinking, such as one's own thoughts and attitudes about one's own life, attitudes about how one lives in one's home, relationships with family and interpersonal relationships, and preferences for things, and to share the diagnostic results with family members and utilize the diagnostic results in home design and renovation. Therefore, the other system and the renovation information proposal system of this embodiment have a high affinity, and a synergistic effect can be expected in realizing a better home.
Even if the renovation information obtained from the renovation information proposal system of this embodiment is simply sent to another system, if it can have a positive effect on the diagnostic results obtained from that other system, it will lead to increased satisfaction for customer U1, which will be a great benefit to both customer U1 and the company to which person in charge U2 belongs.

The other system may also be, for example, a system that manages the browsing history of a website by customer U1. Here, the website refers to a website managed by the company, organization, or group to which person in charge U2 belongs. In other words, the other system is a system that oversees what web pages customer U1 has viewed on the company's website.
The renovation information proposal system of this embodiment transmits the site browsing history of customer U1 to another system (another system server 6). Furthermore, because browsing history data from other company websites is also transmitted to the other system, staff member U2 can investigate trends in site browsing by customer U1. This allows staff member U2 to easily understand the things and subjects that customer U1 is interested in, enabling him or her to provide more accurate suggestions and advice to customer U1.

The other system may be, for example, a system for managing a website that can display information about upcoming events for a family or home in chronological order (chronology 15). This website is also managed by the company, organization, or group to which person U2 belongs.
The renovation information proposal system of this embodiment can transmit a notification 15a encouraging the use of the renovation information proposal system to other systems (other system servers 6). That is, as shown in Fig. 11, the notification 15a encouraging the use of the renovation information proposal system can be displayed on the timeline 15.
The memory unit 1b stores a notification program as described above. When executed by the control unit 1a, this notification program enables the computer of the renovation information proposal device 1 to function as a notification unit. Therefore, the notification unit of the renovation information proposal device 1 of this embodiment can display a notification 15a encouraging the use of the renovation information proposal system on the timeline 15 of the website viewed by the customer U1.
However, the method of sending the notification encouraging use of the renovation information proposal system is not limited to this, and other methods may be used. For example, the notification may be sent directly to the information terminal 3 of the customer U1, or may be sent to the information terminal 4 of the person in charge U2, who may then encourage the customer U1 to use the website.

According to this embodiment, the following excellent effects are achieved.
That is, customer U1 selects from multiple first sub-themes located in a hierarchy below the first main theme, which asks about the ideal lifestyle in a home, in hierarchical order, and renovation information associated with the first sub-theme selected by customer U1 can be derived. In other words, renovation information that will help customer U1 realize the ideal lifestyle in a home that he or she desires can be derived. This allows person U2, who recommends home renovations to customer U1, to fully understand customer U1's true intentions and propose information related to specific renovation methods necessary to realize customer U1's ideal lifestyle. Furthermore, customer U1 himself or herself can understand his or her desires for a home and his or her ideal lifestyle in a home.

Customer U1 can also select themes in hierarchical order from multiple major themes, questions belonging to the major themes, multiple medium themes, questions belonging to the medium themes, and multiple minor themes, gradually narrowing down the themes to reflect customer U1's ideals. This allows staff member U2, who is recommending home renovations to customer U1, to understand customer U1's true intentions as closely as possible and propose information on specific renovation methods necessary to realize customer U1's ideal lifestyle. Customer U1 can also understand his or her own requests for the home and the ideal lifestyle he or she would like to have in the home.

Furthermore, the renovation information associated with the subcategory themes is obtained as a result of the customer U1 selecting multiple themes in hierarchical order and gradually narrowing down the themes that reflect the customer U1's ideals. Therefore, the person in charge U2 who recommends home renovation to the customer U1 can understand the customer U1's true intentions as much as possible and can propose information on specific renovation methods necessary to realize the customer U1's ideal lifestyle.
Furthermore, the renovation information output means can output renovation information associated with themes other than one minor theme. Therefore, renovation information can be narrowed down by multiple themes, so that the person in charge U2 who recommends home renovation to the customer U1 can propose more accurate renovation information.

In addition, the image information in the renovation information includes an image of the renovation example and an explanation of the proposed renovation areas within the image, so customer U1 can fully understand the renovation information by looking at the image and explanation.

Furthermore, customer U1 can select from multiple second sub-themes located at a lower level than the second main theme, which asks about their housing concerns, and remodeling information associated with the second sub-theme selected by customer U1 can be derived. In other words, it is possible to derive the remodeling information that customer U1 is looking for to resolve their housing concerns. This allows person U2, who recommends home remodeling to customer U1, to understand customer U1's true intentions as closely as possible and propose information related to specific remodeling methods necessary to realize customer U1's ideal lifestyle. Customer U1 can also understand their own requests for the home and their ideal lifestyle in the home.

In addition, the theme output means outputs the first main theme and multiple first sub-themes, and the second main theme and multiple second sub-themes in sequence, so that customer U1 can confirm their ideal lifestyle in the home and their concerns about the home all at once in a single flow, which is very efficient.

In addition, the renovation information proposal device 1 transmits to the information terminals 3 and 4 the first sub-theme selected by customer U1 and renovation information associated with the first sub-theme selected by customer U1, so that users including customer U1 can check the process and results of customer U1's theme selection on the information terminals 3 and 4, even if they are in a remote location.

In addition, information terminals 3 and 4 are portable information terminals with camera functionality, and are equipped with augmented reality means for displaying images of renovation examples superimposed on the scenery inside the home, making it possible to display images of renovation examples superimposed on the scenery inside the home owned or lived in by customer U1. This allows customer U1 to get a feel for the atmosphere of the home after renovation before carrying out the renovation.

In addition, the renovation information proposal device 1 uses the renovation information output means to output renovation information associated with the first sub-theme selected by customer U1 and transmits it to the external device 6, allowing the external device 6 to utilize the renovation information transmitted from the renovation information proposal device 1.

In recent years, there has also been a demand to realize a carbon-neutral society by promoting carbon neutrality, which aims to reduce carbon dioxide emissions to virtually zero, and to achieve the targets of the SDGs (Sustainable Development Goals), and various initiatives are being taken in the construction industry.
In this embodiment, home renovations can be promoted, reducing the production of unnecessary waste materials. Furthermore, by renovating homes, residents can continue to live in them. This contributes to the realization of a carbon-neutral society through the promotion of carbon neutrality and the achievement of the SDGs (Goals 11, 12, 13, and 15).
