Description

[Technical Field]

[0001] The present invention relates to a communication system, a communication method, and a program. [Background technology]

[0002] Conventionally, there have been technologies that enable the collection of information on damage suffered by disaster victims and the provision of appropriate assistance at appropriate times. For example, there is a known technology that issues a questionnaire at the time of a disaster, collects information that may affect the breakdown of housing, and analyzes it (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2022-168324 Summary of the Invention [Problem to be solved by the invention]

[0004] While such technology allows residents to obtain information to identify damaged areas, it does not allow them to determine the extent of the damage, which can lead to anxiety. This creates a problem in that disaster victims end up making numerous inquiries to home builders. Therefore, there is a need for a system that can reassure disaster victims.

[0005] Therefore, an object of the present invention is to provide a communication system, a communication method, and a program that can reduce inquiries to home builders in the event of a disaster. [Means for solving the problem]

[0006] (1) One aspect of the present invention is a communication system that interviews residents of a building about the condition of the building and displays the diagnosis results, where the interview items include interview items related to structural damage to the building and interview items related to conditions that are unrelated to structural damage but that make the residents feel anxious. The communication system obtains answers to the interview items, displays the results of a diagnosis about the condition of the building based on the answers to the interview items related to structural damage to the building, and displays supplementary information about the interview items related to conditions that are unrelated to structural damage but that make the residents feel anxious.

[0007] (2) Also, in one aspect of the present invention, in the communication system described in (1) above, the medical interview is conducted at the time of a disaster, and inquiries received at the time of the disaster other than answers to the medical interview items are tallied by item, and among the tallied items, a first group of items that is not related to structural damage to the building but relates to conditions that cause residents to feel anxious, and that satisfy the condition that the number of inquiries received at the time of the disaster other than answers to the medical interview items is equal to or greater than a threshold, is compared with a second group of items that is included in the medical interview items and is not related to structural damage to the building but relates to conditions that cause residents to feel anxious, and items that are included in the first group of items but not included in the second group of items are displayed or notified.

[0008] (3) Furthermore, one aspect of the present invention is a communication system as described in (2) above, in which the questionnaire items are displayed on a resident terminal device possessed by the resident, answers to the questionnaire items are obtained in response to the resident operating the resident terminal device, and the questionnaire is initiated in response to the resident operating a pop-up display based on the occurrence of an earthquake.

[0009] (4) Furthermore, in one aspect of the present invention, in the communication system described in any of (1) to (3) above, answers to questionnaire items regarding conditions that are not related to structural damage to the building but that make residents feel anxious are not used in the diagnosis.

[0010] (5) Furthermore, one aspect of the present invention is a communication system according to any one of (1) to (4) above, wherein the questionnaire items related to structural damage to the building include at least one of the following: an item regarding whether the building is leaning, an item regarding damage to the foundation of the building, and an item regarding the condition of the exterior walls of the building.

[0011] (6) Furthermore, one aspect of the present invention is a communication system as described in any one of (1) to (5) above, wherein the questionnaire items included in the questionnaire, which are not related to structural damage to the building but which cause residents anxiety, include at least one of the following: items related to damage to interior walls or floors caused by furniture, items related to distortion of doors, and items related to the condition of the interior walls of the building.

[0012] (7) Another aspect of the present invention is a communication method that uses a computer to interview residents of a building about the condition of the building and display the diagnosis results, the communication method having an interview process for interviewing residents of the building, including interview items related to structural damage to the building and interview items related to conditions unrelated to structural damage to the building that make the residents feel anxious; an answer acquisition process for acquiring answers to the interview items; a diagnosis result display process for displaying the results of a diagnosis about the condition of the building based on the answers to the interview items related to structural damage to the building; and a supplementary information display process for displaying supplementary information about the interview items related to conditions unrelated to structural damage to the building that make the residents feel anxious.

[0013] (8) Another aspect of the present invention is a program that causes a computer to conduct a questionnaire with residents of a building about the condition of the building and display the diagnosis results, the program comprising: an interview step of conducting a questionnaire with the residents of the building, including questionnaire items related to structural damage to the building and questionnaire items related to conditions unrelated to structural damage to the building that make the residents feel anxious; an answer acquisition step of acquiring answers to the questionnaire items; a diagnosis result display step of displaying the results of a diagnosis about the condition of the building based on the answers to the questionnaire items related to structural damage to the building; and a supplementary information display step of displaying supplementary information about the questionnaire items related to conditions unrelated to structural damage to the building that make the residents feel anxious. [Effects of the Invention]

[0014] According to the present invention, it is possible to provide a communication system, a communication method, and a program that can reduce inquiries to home builders in the event of a disaster. [Brief explanation of the drawings]

[0016] A communication system, a communication method, and a program according to aspects of the present invention will be described in detail below with reference to preferred embodiments and the accompanying drawings. Note that the aspects of the present invention are not limited to these embodiments and include various modifications or improvements. In other words, the components described below include those that would be easily conceivable to a person skilled in the art or that are substantially identical, and the components described below can be combined as appropriate. Furthermore, various omissions, substitutions, or modifications of the components can be made without departing from the spirit of the present invention. Furthermore, in the drawings, the numbers in each structure may differ from the numbers in the actual structures to make each structure easier to understand.

[0017] [Communication System] First, an overview of the communication system 1 and a series of processing flows performed by the communication system 1 will be described with reference to Figures 1 and 2. The communication system 1 is used between a home builder that provides a home and the residents who live in the home. For example, in the event of a disaster, the communication system 1 may be used to support the home builder in formulating a post-disaster inspection plan. Note that the following description is based on the premise that a disaster has occurred, but the occurrence of a disaster is not essential, and the communication system 1 may also be used during normal times.

[0018] FIG. 1 is a diagram illustrating an overview of a communication system according to one embodiment. First, the elements that make up communication system 1 will be described with reference to the diagram. Communication system 1 interviews building residents about the condition of the building and displays the diagnosis results. Specifically, communication system 1 includes at least one self-inspection support device 10 and multiple resident terminal devices 30. The diagram illustrates resident terminal device 30-1, resident terminal device 30-2, and resident terminal device 30-n (n is a natural number greater than or equal to 1) as examples of multiple resident terminal devices 30.

[0019] The self-inspection support device 10 is a device used by home builders. The self-inspection support device 10 presents questionnaire items to the resident terminal device 30. The questionnaire items are preferably displayed during a disaster (particularly after a disaster), but are not limited to this example. The questionnaire items may also be displayed to the resident when there is a possibility that the house has been damaged due to, for example, aging or other reasons.

[0020] The self-inspection support device 10 also acquires answers to the questionnaire items from the resident terminal device 30. The answers may be selected from presented options or may be text information entered by the resident. The answers may also include information such as images or videos showing the condition of the house.

[0021] The self-inspection support device 10 determines the degree of damage to the home based on the acquired answers. The self-inspection support device 10 presents information to the resident based on the determined degree of damage to the home. For example, if the degree of damage to the home is minor, the self-inspection support device 10 presents information to reassure the resident. If the degree of damage to the home is severe, the self-inspection support device 10 may urge the resident to evacuate immediately or arrange for an inspection by the home builder. The self-inspection support device 10 may also enable the resident to make inquiries to the home builder based on the acquired answers.

[0022] The communication system 1 includes a plurality of resident terminal devices 30. The self-inspection support device 10 may comprehensively evaluate the responses obtained from the plurality of resident terminal devices 30 and determine the information to present to the resident.

[0023] The resident terminal device 30 is a device used by a resident. The resident terminal device 30 may be a commonly used device such as a smartphone, tablet terminal, or wearable terminal. The resident terminal device 30 may be configured to perform the functions of the resident terminal device 30 by installing a program on the smartphone, tablet terminal, or wearable terminal. Alternatively, a web app or the like may be used instead of installing a program. The resident terminal device 30 presents questionnaire items to the resident by the self-inspection support device 10. The resident answers the presented questionnaire items. The resident terminal device 30 transmits the obtained answers to the self-inspection support device 10.

[0024] 2 is a sequence diagram illustrating a series of steps in a communication method performed by the communication system according to this embodiment. Next, the series of steps in a communication method performed by the communication system 1 will be described with reference to the same diagram.

[0025] (Step S11) First, the self-inspection support device 10 presents a question about the state of the building to the resident terminal device 30. The question about the state of the building is the questionnaire item described above. Details of the questionnaire items will be described later with reference to FIG. 3. Note that the resident terminal device 30 may present a question about the state of the building to the self-inspection support device 10 in response to the occurrence of a disaster.

[0026] (Step S12) Next, the resident terminal device 30 responds to the questions about the building's condition. Specifically, the resident responds by operating the resident terminal device 30. The response may be made by selecting one of the options set for each questionnaire item, by entering a string of characters in a text box, by transmitting image or video data of the building's condition, or by transmitting audio data such as a voice or environmental sounds related to the questionnaire.

[0027] (Step S13) Next, the self-inspection support device 10 diagnoses the condition of the building based on the obtained answers. The diagnosis is performed by comprehensively considering the answers to the questions about the condition of the building. Note that the questionnaire items according to this embodiment include items that are used in the diagnosis in step S13 and items that are not used in the diagnosis in step S13. The items that are used in the diagnosis and the items that are not used in the diagnosis will be described later with reference to FIGS. 3 to 5, etc.

[0028] (Step S14) Furthermore, the self-inspection support device 10 presents information to the resident terminal device 30 based on the results of the diagnosis. Note that the information presented in step S14 may include information to reassure the resident in addition to the results of the diagnosis of the exterior of the home.

[0029] [Question items] 3 is a diagram showing an example of a medical interview item used by the communication system according to this embodiment. In the figure, an example of a medical interview item presented from the self-inspection support device 10 to the resident terminal device 30 in step S11 described above is indicated by the symbol D10. Note that the medical interview items shown in the figure are merely an example, not specific interview content. Furthermore, more medical interview items may be included in addition to the example shown in the figure.

[0030] The questionnaire items according to this embodiment include a questionnaire item related to structural damage to the building, as indicated by reference symbol D11, and a questionnaire item related to a state that is unrelated to structural damage to the building but that makes the occupants feel uneasy, as indicated by reference symbol D12. The self-inspection support device 10 performs the diagnosis in step S13 described above based on the answers to the questionnaire item related to structural damage to the building (reference symbol D11). On the other hand, the answers to the questionnaire item related to a state that is unrelated to structural damage to the building but that makes the occupants feel uneasy (reference symbol D12) are not used in the diagnosis in step S13 described above.

[0031] Specifically, the questionnaire items related to structural damage to the building (D11) include an item about whether the building is leaning (D111), an item about damage to the building's foundation (D112), and an item about the condition of the building's exterior walls (D113). Furthermore, the questionnaire items related to conditions that may cause residents anxiety but are not related to structural damage to the building (D12) include an item about damage to interior walls or floors caused by furniture (D121), an item about distortion of doors (D122), and an item about the condition of the building's interior walls (D123).

[0032] The questionnaire items related to structural damage to the building, such as those indicated by reference symbol D11, and the questionnaire items related to conditions that are unrelated to structural damage to the building but that make residents feel anxious, such as those indicated by reference symbol D12, may be arranged in order as questionnaire items, but it is preferable that they are interwoven alternately (for example, one question at a time). By conducting the questionnaire in an interwoven manner in this way, respondents (residents) can give natural answers to the questionnaire, and it is expected that more accurate answers can be obtained.

[0033] [Generate display information] Next, with reference to FIGS. 4 to 6, an example of a method for generating information to be displayed on the resident terminal device 30 as a result of the medical interview will be described.

[0034] 4 is a diagram for explaining a first method for generating information displayed by the communication system according to this embodiment. First, with reference to the diagram, a first example of a method for generating information displayed by the communication system 1 will be explained.

[0035] The self-inspection support device 10 acquires answers to questions (questions about the state of the building) (symbol D20) from the resident terminal device 30. The answers include answers to questions about structural damage to the building (symbol D21) and answers to questions about conditions that make the resident feel uneasy (symbol D22).

[0036] Next, based on the answers to the questionnaire items related to structural damage of the building (reference symbol D21), a diagnosis is made (reference symbol D23) about the condition of the building. This diagnosis is the diagnosis made in step S13 described above. For example, if the building is leaning, if damage is found in the foundation of the building, or if damage is found in the exterior walls of the building, it is diagnosed that there is a high possibility that the building is structurally damaged.

[0037] Furthermore, based on the answers to the questionnaire items (D22) regarding the conditions that the resident feels uneasy about, supplementary information to be presented to the resident is identified (D24). For example, if there is damage to the interior walls or floors caused by furniture, the resident may feel uneasy. However, in such a case, it is unlikely that the building is structurally damaged. Similarly, if there is a distortion in the door or damage is found in the interior walls of the building, the resident may feel uneasy, but it is unlikely that the building is structurally damaged. Therefore, in such cases, the purpose is to reassure the resident by presenting supplementary information to the resident.

[0038] The self-inspection support device 10 transmits the results of the diagnosis of the building condition (symbol D23) and the results of the identification of supplemental information to be presented to the resident (symbol D24) to the resident terminal device 30 and presents them to the resident. In other words, the self-inspection support device 10 displays the results of the diagnosis of the building condition based on the answers to the questionnaire items related to structural damage to the building on the resident terminal device 30. The self-inspection support device 10 also displays supplemental information on the questionnaire items related to conditions that are not related to structural damage to the building but that make the resident feel uneasy on the resident terminal device 30. Thereafter, if necessary, an on-site inspection by the house builder may be conducted.

[0039] 5 is a diagram for explaining a second method for generating information displayed by the communication system according to this embodiment. Next, a second example of the method for generating information displayed by the communication system 1 will be explained with reference to the same figure. In the second example, in addition to the first example explained with reference to FIG. 4, the items indicated by symbols D26 and D27 are added. In the explanation of FIG. 5, the items already explained with reference to FIG. 4 may be given the same symbols and explanations thereof may be omitted.

[0040] Reference symbol D28 indicates other inquiries. Other inquiries are items that are not included in the questionnaire items related to structural damage to the building (reference symbol D11) and the questionnaire items related to conditions that are unrelated to structural damage to the building but that make residents feel anxious (reference symbol D12), as explained with reference to FIG. 3. Other inquiries may be acquired as part of the questionnaire items (reference symbol D20), or may be inquiries received from residents by a method other than the questionnaire. Methods other than the questionnaire broadly include inquiries by email, telephone, etc.

[0041] In this embodiment, it is preferable that the other inquiries are those made when a disaster occurs (i.e., when residents are affected by the disaster). By referring to the inquiries made when a disaster occurs, it becomes possible to take into consideration information about what residents may be worried about when a disaster occurs. It is also possible for the "disaster" to be a disaster that is not limited to the disaster that the communication system 1 targets (a disaster that is currently occurring), but may be a disaster that occurred in the past. When considering information about a past disaster, it is preferable that the disaster is similar to the disaster that is currently occurring.

[0042] Next, other inquiries are tallied (reference symbol D27). Specifically, other inquiries (reference symbol D28) are tallied by item. As a result of the tallying, items included in the medical interview and items other than the medical interview are divided into a first item group and a second item group. Based on the first item group and the second item group, it is determined whether to present the information to the resident.

[0043] 6 is a diagram for explaining the first item group and the second item group that are tallied by the communication system according to this embodiment. The first item group and the second item group will be explained with reference to the same figure.

[0044] The first item group is a group that includes items that are not related to structural damage to the building but that concern the residents and that satisfy the condition that the number of inquiries received other than answers to the questionnaire items at the time of the disaster is above a threshold. The number of inquiries received other than answers to the questionnaire items is above a threshold, which indicates that the residents are highly concerned.

[0045] The second group of items is a group of items included in the questionnaire items (code D10), and are items related to conditions that occupants feel uneasy about but are not related to structural damage to the building. Note that for this second group of items, supplementary information has already been specified in code D24, and the information has been presented to residents.

[0046] The self-inspection support device 10 compares the first item group with the second item group, and displays or notifies the resident terminal device 30 of items that are included in the first item group but not in the second item group. In other words, the self-inspection support device 10 displays items that are not included in the medical interview items but that are of great interest to the resident as other inquiries.

[0047] [Self-inspection support method] 7 is a flowchart showing a series of steps in the self-inspection support method according to this embodiment, which will be described with reference to the same figure.

[0048] (Step S21) First, an interview is designed. The interview design includes designing an interview to identify matters related to structural damage of the building and designing an interview to determine matters that are likely to cause anxiety to residents in the event of a disaster. Specifically, in step S12, the items indicated by symbols D11 and D12 shown in FIG. 3 may be created.

[0049] (Step S22) Next, the questionnaire designed in step S21 is presented to the resident. The presented questionnaire includes questionnaire items (symbol D11) related to structural damage to the building, as shown in Fig. 3, and questionnaire items (symbol D12) designed in step S21 related to conditions that make the resident feel anxious.

[0050] (Step S23) Based on the conditions described below, the self-inspection support device 10 repeatedly performs the processes of steps S24 and S25.

[0051] (Step S24) First, the self-inspection support device 10 acquires a response to the medical interview from the resident terminal device 30.

[0052] (Step S25) When a response to the medical interview is obtained, the self-inspection support device 10 checks whether there is a possibility that structural damage has occurred to the building. If there is one or more items that may indicate that structural damage has occurred to the building, the process proceeds to step S28. If there is no item that may indicate that structural damage has occurred to the building, the process proceeds to step S26.

[0053] (Step S26) Here, the self-inspection support device 10 waits for a response from the next resident terminal device 30, and steps S23 to S26 are looped. For resident terminal devices 30 that have already performed steps S23 to S26, the self-inspection support device 10 performs the process of step S27 or step S28, which will be described later.

[0054] (Step S27) If there is no item that may indicate structural damage to the building, the self-inspection support device 10 generates a response screen indicating that there are no structural damage targets. The response screen displays items that will alleviate the anxiety that the resident is presumed to have, based on the response from the resident.

[0055] (Step S28) If there is one or more items that may indicate structural damage to the building, the self-inspection support device 10 generates a response screen for the structural damage target. The response screen displays, for example, items urging immediate evacuation because structural damage to the building may have occurred, and items indicating that an on-site inspection by the home builder will be conducted.

[0056] [Design support method] 8 is a flowchart showing a series of steps in the design support method according to this embodiment. The series of steps in the design support method according to this embodiment will be described with reference to this figure. The processing shown in this figure can also be said to be an example of the processing of step S21 described above. Although step S21 described above may be performed at any time, the processing shown in this figure particularly shows an example of processing performed when a disaster occurs.

[0057] (Step S31) First, earthquake Y occurs. Note that earthquake Y is an example of a disaster. The disaster targeted by the communication system 1 according to this embodiment may be any disaster that causes damage to buildings. For example, it may be a disaster such as a flood or a typhoon.

[0058] (Step S32) Next, a comparison is made between the earthquake Y that occurred in step S31 and data based on earthquake X that occurred in the past. Earthquake X that occurred in the past is also an example of a disaster, just like earthquake Y. Earthquake X that occurred in the past may be any disaster that caused damage to a building, such as a flood or typhoon. It is desirable that earthquakes X and Y are similar types of disasters. The data may be signals (sound, images, video, sensor data, etc.) related to the disaster or building materials, or may be acquired as part of the questionnaire items (symbol D20), or inquiries received from residents via methods other than the questionnaire. Methods other than the questionnaire widely include inquiries by email, telephone, etc. As a result of the comparison, if there is a difference, the process proceeds to step S33. If there is no difference, the process ends.

[0059] (Step S33) Here, if there is a difference in the comparison between the earthquake Y that occurred in step S31 and the data based on the earthquake X that occurred in the past, it can be said that the items that make the residents feel anxious are changing. For example, the residents' anxieties may change due to the influence of changes in the external environment, such as technological developments in buildings or public common sense. In such cases, the past medical interviews and the answers corresponding to those interviews may not be applicable as they are. Therefore, in such cases, the change is notified to the person in charge of creating the medical interview. The person in charge of creating the medical interview creates a new medical interview in response to the change. Note that the person in charge of creating the medical interview may be a human or a computer.

[0060] [Screen Configuration] Next, a specific example of a display screen to be displayed on the resident terminal device 30 will be described with reference to Figures 9 to 13. Reference symbols D30 to D70 shown in Figures 9 to 13 indicate an example of a display screen of the self-inspection support tool displayed on the resident terminal device 30 by the self-inspection support device 10. Reference symbol D30 is displayed on a display unit (not shown), such as a liquid crystal display or an organic EL (Electroluminescence) display, provided on the resident terminal device 30 owned by the resident.

[0061] 9 is a screen configuration diagram showing an example of the start screen of the self-inspection support tool according to this embodiment. Reference numeral D30 in the drawing indicates an example of the start screen of the self-inspection support tool displayed on the resident terminal device 30 by the self-inspection support device 10.

[0062] Reference symbol D31 is a pop-up display that is displayed on the display unit of the resident terminal device 30. The pop-up display is triggered to appear on the standby screen or sleep screen when a disaster such as an earthquake occurs. Reference symbol D31 displays a message such as "An earthquake has occurred. Do you want to start the self-inspection support tool?", prompting the user to select whether or not they wish to start the self-inspection support tool.

[0063] Here, when the "YES button" D32 is operated, the medical interview begins. In other words, the medical interview begins in response to the resident operating a pop-up display based on the occurrence of an earthquake. Furthermore, when the "NO button" D33 is operated, the pop-up display closes and the screen returns to the original screen (for example, the standby screen or sleep screen). Note that these "YES button" and "NO button" may be realized by other operation methods, such as clicking on the screen and swiping, respectively.

[0064] FIG. 10 is a screen configuration diagram showing a first example of an inquiry screen of the self-inspection support tool according to this embodiment. Reference numeral D40 shown in the figure indicates an example of an inquiry screen of the self-inspection support tool displayed on the resident terminal device 30 by the self-inspection support device 10. The inquiry screen shown in the figure may be displayed by operating the "YES button" indicated by reference numeral D32 on the start screen indicated by reference numeral D30. Reference numeral D40 has reference numerals D41, D42, D43, D44, D45, and D46 as screen components.

[0065] Reference symbol D41 indicates how far the current self-inspection has progressed on an 11-point scale. In the example shown, it indicates that the self-inspection has progressed to the second point out of 11 points.

[0066] Reference symbol D42 indicates the content of the medical interview. That is, the medical interview items according to this embodiment are displayed on the resident terminal device owned by the resident. Specifically, in the illustrated example, the first item out of 10 items is displayed, and the content of the medical interview is displayed as "Are there any cracks in the wallpaper (wall covering) or wall tiles in the room?" Note that this medical interview content corresponds to the item indicated by reference symbol D123 in FIG. 3.

[0067] Reference number D43 provides additional explanation regarding the interview content of reference number D42. Specifically, the additional explanation states, "Symptoms tend to appear around room doors and stairs." Additionally, as additional explanation for areas of concern, the additional explanation states, "Cracks and peeling in the wallpaper may also be caused by damage to the underlying plasterboard. Please rest assured that damage to the plasterboard does not have a direct impact on the structure." In this way, interviews that are sensitive to the residents' anxieties aim to alleviate their concerns, so in addition to asking questions, information is also provided to alleviate their anxieties.

[0068] Reference numeral D44 displays a photograph representing the medical interview text shown in reference numeral D42. By displaying such a photograph, even residents who have no knowledge of inspections can answer the questions without placing too much burden on them. To make it easy for even residents who have no knowledge of inspections to answer, it is preferable to present medical interview information with concise questions and answers, as well as supplementary images, for each inspection location.

[0069] Symbols D45 and D46 are selection buttons for obtaining answers to the medical interview. Symbol D45 is a selection button for answering "yes," and symbol D46 is a selection button for answering "no." The resident answers the medical interview by selecting either the selection button D45 or D46. It can also be said that the answers to the medical interview items are obtained in response to the resident operating the resident terminal device 30.

[0070] FIG. 11 is a screen configuration diagram showing a second example of the questionnaire screen of the self-inspection support tool according to this embodiment. Reference numeral D50 in the figure indicates an example of the questionnaire screen of the self-inspection support tool displayed on the resident terminal device 30 by the self-inspection support device 10, similar to the display screen of reference numeral D50 described above. The questionnaire screen of reference numeral D50 corresponds to reference numeral D11 in FIG. 3 and is a questionnaire screen for questions related to structural damage to the building, and differs from the questionnaire screen of reference numeral D40, which corresponds to reference numeral D12 in FIG. 3 and is a questionnaire screen for questions related to conditions that cause anxiety to the resident. Reference numeral D50 includes reference numerals D51, D52, D53, D54, D55, D56, and D57 as screen components. Note that reference numeral D51 is similar to reference numeral D41, and therefore its description will be omitted.

[0071] Reference numeral 52 indicates the content of the medical interview. Specifically, in the illustrated example, the second item out of 10 items is displayed, and the content of the medical interview is displayed as "When you are at home, do you feel that the floor is tilted to the point that it makes you feel unwell?" Reference numeral D53 displays a photograph representing the medical interview text shown in reference numeral D52.

[0072] Similar to the symbols D45 and D46, the symbols D54 and D55 are selection buttons for obtaining answers to the medical interview.

[0073] Reference symbol D56 indicates what should be confirmed through the interview. In the example shown, it specifically states, "Confirm whether liquefaction of the ground occurs during an earthquake, and whether subsidence of the ground or house settlement due to movement of retaining walls on developed land has caused tilting of the building or damage to underground pipes for gas, water, and sewerage, etc."

[0074] Code D57 indicates the reason why the extent of damage can be grasped even through a simple medical interview. In the example shown, it specifically states, "Based on the standard for how people perceive tilt, by having them answer about their physical sensations, we can safely grasp the possibility of harmful ground subsidence and other problems. The standard is that people start to feel tilt when the floor tilt exceeds 3 / 1000, and when the tilt is 6 / 1000 or more, it is said that physical effects such as dizziness and nausea will occur." In addition to this information, code D57 should preferably display the source of the information (for example, the name of a literature reference, etc.).

[0075] The displays shown in symbols D56 and D57 are aimed at experts who have knowledge of inspections and want to understand the intent of the medical interview. Specifically, symbol D56 provides supplementary explanations with specialized information. In other words, symbol D56 can be said to be a specialized supplementary explanation added to the concise medical interview content of symbol D52. By displaying such information, experts who have knowledge of inspections and want to understand the intent of the medical interview can be prevented from feeling anxious.

[0076] 12 is a screen configuration diagram showing an example of a screen displayed as a result of a medical interview conducted by the self-inspection support tool according to this embodiment. Reference numeral D60 in the figure indicates an example of a diagnosis result display screen of the self-inspection support tool, which is displayed on the resident terminal device 30 by the self-inspection support device 10. The diagnosis result display screen of reference numeral D60 displays the results of a diagnosis conducted by the self-inspection support device 10 as a result of conducting a medical interview such as those shown in reference numerals D40 and D50. Reference numeral D60 has reference numerals D61, D62, D63, D64, D65, and D66 as screen components.

[0077] Reference symbol D61 indicates whether the currently displayed screen is "Condition Assessment," "Inspection / Diagnosis," or "Registration." In the illustrated example, reference symbol D60 is the "Inspection / Diagnosis" display screen.

[0078] Reference symbol D62 indicates the possibility of structural damage obtained as a result of diagnosing the results of the medical interview. In the example shown, the possibility of structural damage is shown to be low. As shown in the figure, the possibility of structural damage is displayed as a binary value of "high" or "low," but the degree of structural damage may also be displayed.

[0079] Reference D63 shows the details of the results shown in reference D62. Specifically, in the example shown, it says, "Based on your responses, we have confirmed that the possibility of structural damage to the building is low. The situation around the building is constantly changing, with successive earthquakes, fires, flooding, and so on. If you sense anything unusual, please take immediate action to protect yourself."

[0080] Although it is partially omitted in the figure, reference numeral D63 may display a notice such as that the results of the diagnosis will be fed back. Specifically, in the example shown in the figure, it displays the following: "When using the feedback results, we will feed back the diagnosis content based on the customer's inspection results..."

[0081] Symbols D64, D65, and D66 are selection buttons that allow the resident to select what action to take in response to the diagnosis results. By selecting symbol D64, the resident can register the results of the self-inspection. Selecting this selection button may have the function of linking to a contact form for the damaged area. By selecting symbol D65, the resident can exit the self-inspection support tool. Furthermore, by selecting symbol D66, the resident can return to the previous display screen.

[0082] FIG. 13 is a screen configuration diagram showing an example of an inspection request screen by the self-inspection support tool according to this embodiment. Reference numeral D70 in the figure shows an example of the inspection request screen of the self-inspection support tool displayed on the resident terminal device 30 by the self-inspection support device 10. The inspection request screen of reference numeral D70 displays a display screen when a resident requests an inspection from a home builder when a diagnosis result such as that shown in reference numeral D60 indicates a high possibility of structural damage. Reference numeral D70 has reference numerals D71, D72, D73, and D74 as screen components.

[0083] Like reference symbol D61, reference symbol D71 indicates whether the currently displayed screen is "Condition Assessment," "Inspection / Diagnosis," or "Registration." In the illustrated example, reference symbol D70 is the display screen for "Inspection / Diagnosis."

[0084] Reference numeral D72 indicates a request to enter contact information. Specifically, in the example shown, it says, "We will confirm the details of the damaged area based on your response. Our representative will contact you shortly, so please enter your contact information."

[0085] Code D73 displays the same caution as code D63 mentioned above. Specifically, in the example shown, it reads, "The situation around the building is constantly changing due to successive earthquakes, fires, flooding, etc. If you notice anything unusual, please take immediate action to protect yourself. When using the feedback results, we will provide feedback on the diagnosis based on the customer's inspection results..."

[0086] Reference symbol D74 is a selection button for transitioning to a screen for inputting contact information. By operating reference symbol D74, the resident can transition to a screen for inputting contact information.

[0087] Code D75 is a selection button for returning to the previous screen. By selecting code D75, the resident can return to the previous display screen.

[0088] [Function Configuration] FIG. 14 is a functional configuration diagram showing an example of the functional configuration of the self-inspection support device according to this embodiment. An example of the functions of the self-inspection support device 10 to realize the above-described functions will be described. The self-inspection support device 10 includes an acquisition unit 11, a control unit 13, and an output unit 15. Each of these functional units is realized, for example, using electronic circuits. Each functional unit may also include internal storage means such as a semiconductor memory or a magnetic hard disk drive, as necessary.

All or part of each functional unit may also be realized by a combination of software and hardware.

[0089] The acquisition unit 11 acquires information from the resident terminal device 30. Examples of the information acquired by the acquisition unit 11 include answers to medical interviews, requests for inspections made in response to diagnosis results, contact information, etc.

[0090] The control unit 13 controls the display screen displayed on the display unit of the resident terminal device 30 based on the information acquired by the acquisition unit 11. The control of the display screen displayed on the display unit of the resident terminal device 30 is performed by outputting information from the output unit 15.

[0091] The output unit 15 outputs information to the resident terminal device 30. The information transmitted from the output unit 15 may be the display screen itself, or information relating to the elements that make up the display screen. Specifically, the output unit 15 outputs information relating to the medical interview items, the contents of the medical interview, the results of the medical interview, etc. to the resident terminal device 30, and causes it to be displayed on the display screen of the resident terminal device 30.

[0092] [Internal configuration] FIG. 15 is a block diagram showing an example of the internal configuration of the self-inspection support device according to this embodiment. At least some of the functions of the self-inspection support device 10 can be implemented using a computer. As shown in the figure, the computer includes a central processing unit 901, a RAM 902, an input / output port 903, input / output devices 904 and 905, and a bus 906. The computer itself can be implemented using existing technology. The central processing unit 901 executes instructions contained in a program read from the RAM 902 or the like. In accordance with each instruction, the central processing unit 901 writes data to the RAM 902, reads data from the RAM 902, and performs arithmetic and logical operations. The RAM 902 stores data and programs. Each element included in the RAM 902 has an address and can be accessed using the address. RAM stands for "random access memory." The input / output port 903 is a port through which the central processing unit 901 exchanges data with external input / output devices. The input / output devices 904 and 905 are input / output devices. The input / output devices 904 and 905 exchange data with the central processing unit 901 via the input / output port 903. The bus 906 is a common communication path used within the computer. For example, the central processing unit 901 reads and writes data from and to the RAM 902 via the bus 906. Also, for example, the central processing unit 901 accesses the input / output port via the bus 906. Furthermore, all or part of the functional units provided in the self-inspection support device 10 may be realized using hardware such as an ASIC, a PLD, or an FPGA. Furthermore, all or part of the functional units may be realized by a combination of software and hardware.

[0093] [Summary of the embodiment] According to the embodiment described above, the communication system 1 interviews residents of a building about the condition of the building and displays the diagnosis results. The interview items include interview items related to structural damage to the building and interview items related to conditions unrelated to the structural damage that cause the residents anxiety. The communication system 1 also acquires responses to the interview items from the residents, displays the results of a diagnosis about the condition of the building based on the answers to the interview items related to the structural damage of the building, and displays supplemental information related to the interview items related to conditions unrelated to the structural damage that cause the residents anxiety. According to this embodiment, by displaying the results of a diagnosis about the condition of the building based on the answers to the interview items related to the structural damage of the building as well as supplemental information related to the interview items related to conditions unrelated to the structural damage of the building, the anxiety of the residents can be alleviated. Therefore, according to this embodiment, the number of inquiries to home builders can be reduced in the event of a disaster.

[0094] According to the above-described embodiment, the medical interview is conducted at the time of a disaster. The communication system 1 also aggregates inquiries received at the time of the disaster other than answers to the medical interview items by item. The communication system 1 performs display or notification based on a first item group and a second item group. The first item group is an item group among the aggregated item groups that is related to a state that is unrelated to structural damage to the building but that makes residents feel anxious, and that satisfies the condition that the number of inquiries received at the time of the disaster other than answers to the medical interview items is equal to or greater than a threshold. The second item group is an item group included in the medical interview items and is related to a state that is unrelated to structural damage to the building but that makes residents feel anxious. The communication system 1 displays or notifies items that are included in the first item group but not in the second item group.

[0095] When mixing in information about voices that cause anxiety to residents, the residents' anxieties change due to changes in the residents' external environment (technological developments in buildings, common sense, etc.). Therefore, it is preferable that the questionnaire items that address these anxieties change in line with changes in the residents. According to this embodiment, changes in the tendency of inquiries from residents can be automatically detected and notified to the person in charge of creating the questionnaire.

[0096] Furthermore, according to the above-described embodiment, the questionnaire items are displayed on the resident terminal device 30 owned by the resident. Responses to the questionnaire items are acquired in response to the resident operating the resident terminal device 30, and the questionnaire is initiated in response to the resident operating a pop-up display in response to the occurrence of an earthquake. By adopting such a configuration, it is possible to alleviate the anxiety of residents without delay in the event of a disaster. Therefore, according to this embodiment, it is possible to reduce inquiries to the home builder in the event of a disaster.

[0097] Furthermore, according to the above-described embodiment, responses to questionnaire items regarding conditions that occupants feel anxious about but are not related to structural damage to the building are not used in the diagnosis. In other words, responses to questionnaire items regarding conditions that occupants feel anxious about but are not related to structural damage to the building are interwoven into the questionnaire, even though they are not used in the diagnosis. By adopting such a configuration, the communication system 1 can acquire information regarding the anxieties of disaster victims and present information to alleviate the anxieties.

[0098] Furthermore, according to the above-described embodiment, the questionnaire items related to structural damage of the building include at least one of an item related to whether the building is leaning, an item related to damage to the foundation of the building, and an item related to the condition of the exterior walls of the building. According to this embodiment, a diagnosis related to structural damage of the building can be made based on these questionnaire items.

[0099] Furthermore, according to the above-described embodiment, the questionnaire items related to conditions that cause anxiety to residents but are not related to structural damage to the building include at least one of items related to damage to interior walls or floors caused by furniture, items related to distortion of doors, and items related to the condition of the interior walls of the building. According to this embodiment, information to alleviate the anxiety felt by residents can be presented based on such questionnaire items.

[0100] Note that all or part of the functions of each unit of the self-inspection support device 10 in the above-described embodiment may be realized by recording a program for realizing these functions on a computer-readable recording medium, and reading and executing the program recorded on the recording medium into a computer system. Note that the term "computer system" here includes hardware such as an OS and peripheral devices.

[0101] Furthermore, "computer-readable recording media" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, as well as storage units such as hard disks built into computer systems. Furthermore, "computer-readable recording media" may also include devices that dynamically store programs for a short period of time, such as communication lines when transmitting programs over networks like the Internet or communication lines like telephone lines, or devices that store programs for a fixed period of time, such as volatile memory within computer systems that serve as servers or clients in such cases. Furthermore, the above-mentioned programs may be programs that realize some of the aforementioned functions, or may be programs that can realize the aforementioned functions in combination with programs already stored in the computer system.

[0102] Furthermore, the effects described in this specification are merely descriptive or exemplary and are not limiting. In other words, the technology according to the present disclosure may achieve other effects in addition to or in place of the above-described effects that would be apparent to those skilled in the art from the description of this specification. Furthermore, the present invention is not limited to these embodiments, and various modifications and substitutions can be made within the scope of the present invention. [Explanation of symbols]
