[0004] [Patent Document 1] JP 2023-12182 A Summary of the Invention [Problem to be solved by the invention]

[0005] When installing a sensor inside a building, it is necessary to determine the appropriate location for the sensor. However, the location of the sensor varies from building to building depending on the structure and usage of the building, and therefore must be considered and determined for each building individually. When installing a sensor in a newly constructed building, the location of the sensor must be determined taking into account the structure and usage of the building.

[0006] Therefore, the present invention has been made in consideration of the above problems, and an object of the present invention is to provide an information processing device and a method for presenting sensor installation positions that are capable of determining appropriate sensor installation positions according to the building structure, usage conditions, etc. [Means for solving the problem]

[0007] The above object can be achieved by the information processing device of the present invention, which includes a first acquisition unit that acquires first information regarding the structure inside a building, a second acquisition unit that acquires second information regarding installation conditions of a sensor installed inside the building, a third acquisition unit that acquires third information regarding the installation pattern of equipment other than the sensor inside the building, a first setting unit that sets the installation position of the sensor inside the building based on the first information, the second information, and the third information so as to be a position that satisfies the installation conditions and is based on the installation pattern, and a presentation unit that presents the set installation position of the sensor.

[0008] In the information processing device of the present invention, the sensor installation position is set based on the first information, the second information, and the third information, and therefore an appropriate sensor installation position is presented. As a result, an appropriate sensor installation position can be determined according to the structure and usage status of the building.

[0009] In addition, the first setting unit may set the number of sensors to be installed inside the building based on the range in which the sensors indicated by the second information can detect, and set the installation positions of each of the set number of sensors based on the first information, the second information, and the third information. With the above configuration, the installation position of each sensor is set according to the number of sensors based on the range that the sensor can detect, and therefore an appropriate sensor installation position is presented for each sensor. As a result, an appropriate sensor installation position can be determined for each sensor according to the structure of the building, the usage situation, etc.

[0010] In addition, the first setting unit may set the number of sensors to be installed inside the building based on at least one of the number of rooms inside the building and the number of partitions in the rooms indicated by the first information, and set the installation positions of each of the set number of sensors based on the first information, the second information, and the third information. With the above configuration, the installation positions of the sensors are set according to the number of sensors based on at least one of the number of rooms in the building and the number of partitions in the rooms, so that an appropriate installation position for each sensor is presented. As a result, an appropriate installation position for each sensor can be determined according to the structure of the building, the usage situation, etc.

[0011] In addition, the information processing device further includes a second setting unit that sets a sensor installation space inside the building based on at least one of the layout, room shape, and partition position of the interior of the building indicated by the first information, and the first setting unit may set the number of sensors to be installed in the sensor installation space according to the relationship between the size of the sensor installation space and the range capable of detection by the sensor indicated by the second information. With the above configuration, the installation positions of the sensors are set according to the number of sensors depending on the relationship between the size of the sensor installation space and the range in which the sensor can be detected indicated by the second information, so that an appropriate sensor installation position is presented for each sensor. As a result, it is possible to determine an appropriate sensor installation position for each sensor depending on the structure of the building, the usage situation, etc.

[0012] The second setting unit may set the sensor installation space based on information on a space in which the sensor cannot be installed, which information is indicated by the second information. With the above configuration, the sensor installation position is set based on the sensor installation space that takes into account the space in which the sensor cannot be installed, and therefore a more appropriate sensor installation position is presented. As a result, a more appropriate sensor installation position can be determined according to the structure and usage status of the building.

[0013] In addition, the information processing device may further include a fourth acquisition unit that acquires fourth information regarding the usage conditions of the building, and the first setting unit may set the installation location of the sensor based on the first information, the second information, the third information, and the fourth information. With the above configuration, the sensor installation position is set based on the building usage conditions, so that a more appropriate sensor installation position is presented. As a result, a more appropriate sensor installation position can be determined according to the building structure, usage conditions, etc.

[0014] Moreover, the third acquisition unit may acquire third information indicating an installation pattern to be set according to the fourth information, and the first setting unit may set the installation position of the sensor based on the third information. With the above configuration, the sensor installation position is set based on the installation pattern set according to the fourth information, so that a more appropriate sensor installation position is presented. As a result, a more appropriate sensor installation position can be determined according to the structure and usage status of the building.

[0015] The third information may also be information regarding an installation pattern adopted in a building that is currently being used as a residence or has been used in the past. With the above configuration, the sensor installation position is set based on a proven installation pattern, so that a more appropriate sensor installation position is presented. As a result, a more appropriate sensor installation position can be determined according to the structure of the building, the usage situation, etc.

[0016] In addition, the above-mentioned problem is solved by the sensor installation position presentation method of the present invention, which acquires first information on the structure inside a building, acquires second information on the installation conditions of a sensor to be installed inside the building, acquires third information on the installation pattern of equipment other than the sensor inside the building, and based on the first, second and third information, sets the installation position of the sensor inside the building to be a position that satisfies the installation conditions and is based on the installation pattern, and presents the set installation position of the sensor. By using the method for presenting a sensor installation position of the present invention, an appropriate sensor installation position is presented, and as a result, an appropriate sensor installation position can be determined according to the structure and usage situation of the building. Effect of the Invention

[0017] According to the present invention, it is possible to provide an information processing device and a method for presenting a sensor installation position that are capable of determining an appropriate sensor installation position according to the structure and usage situation of a building, etc. [Brief description of the drawings]

[0019] Hereinafter, one embodiment of the present invention (hereinafter, this embodiment) will be described with reference to the accompanying drawings 1 to 11. In the following embodiments, a "house" is given as an example of a building; however, the present invention can be implemented in buildings other than houses, such as facilities such as offices, stores, hospitals or schools, and buildings within factories, as well as buildings for various other purposes.

[0020] In addition, in this specification, the concept of "device" includes a single device that performs a specific function by itself, and also includes a combination of multiple devices that are distributed and exist independently but work together (in cooperation) to perform a specific function.

[0021] In addition, since the basic information processing technologies (communication / transmission technology, information acquisition technology, information recording technology, information processing technology, information analysis technology, image processing technology, and visualization technology, etc.) required to realize the contents of this embodiment are well-known technologies, explanations thereof will be omitted.

[0022] <<Outline of sensor installation position presentation according to this embodiment>> First, an overview of presentation (hereinafter, referred to as the present presentation) performed using the information processing device and the method for presenting a sensor installation position according to the present embodiment will be described with reference to FIGS. Fig. 1 is a diagram showing an example of a floor plan inside a house. Figs. 2 to 5 are diagrams showing an example of a procedure for setting the installation position of a sensor for the floor plan shown in Fig. 1, and are arranged in chronological order from Fig. 2 to Fig. 5. Figs. 6 to 8 are diagrams showing an example of a procedure for setting the installation position of a sensor for a floor plan other than Fig. 1, and are mainly used in the following explanation to supplement the example shown in Figs. 1 to 5.

[0023] This presentation presents the installation location of the sensor inside the house (inside the building), and more specifically, sets the installation location of the sensor inside the house based on the first information, second information, and third information described below, and presents the set installation location of the sensor.

[0024] "Interior of the home" refers to the interior space of the home used by the occupants of the home (hereinafter also referred to as "subjects"), and more specifically, refers to the entire space of the home including all spaces such as the kitchen, dining room, living room, Western-style room, bathroom, toilet, washroom, hallway, entrance, and closet, as shown in Figure 1.

[0025] The "sensor" is a non-contact sensor that acquires vital information, position information, posture information, and the like of a target body part of a subject staying in a house. Vital information includes, for example, heart rate, heart rate variability, respiratory rate, blood pressure, body temperature, and the like. Position information includes, for example, the walking speed of the subject, and the like. Posture information includes, for example, whether the subject has fallen, and the like. The sensor may be a known sensor, for example a vital sensor that obtains vital information of a target area in a non-contact manner using a microwave Doppler sensor or a millimeter wave Doppler sensor. The sensor may also be a laser sensor that obtains position information and posture information of a subject by shining emitted laser light on the subject and receiving the reflected light with a light receiving unit. The sensor may also be an infrared sensor (including an infrared thermography camera, etc.) that visualizes body temperature based on the amount of infrared light emitted from the subject. One or more sensors are installed inside the house.

[0026] (Regarding information 1) The "first information" is information regarding the internal structure of the house, and more specifically, information obtained from drawings of the house that is the subject of this presentation. "Drawings" is interpreted broadly and includes two-dimensional drawings and three-dimensional drawings, etc. An example of a two-dimensional drawing is a floor plan as shown in Figure 1, and in the case of a multi-story house, it includes floor plans (floor plans) showing the configuration of each floor. "Information obtained from the drawings" includes the number of rooms, floor plan, shape of the rooms, number of partitions within the rooms, location of the partitions, and space use.

[0027] A "room" refers to a space enclosed by a floor, ceiling, and walls (including doors and windows). Therefore, even if the space within a room is divided by a partition (described later), if the partition is separated from at least one of the floor, ceiling, and walls, and adjacent spaces communicate with each other through the separated space, the room is treated as one room. To be more specific, in the example shown in FIG. 1, a pair of partitions W that separate the space are located between the kitchen and dining room, but the spaces that make up the kitchen, dining room, and living room communicate with each other. Therefore, in this case, the spaces that make up the kitchen, dining room, and living room are treated as one room. Hereinafter, a room in which the kitchen, dining room, and living room are integrated is also referred to as an LDK or an integrated LDK room. In this embodiment, a room is defined as a space in which a subject stays for a predetermined time or more. Therefore, in the example shown in Fig. 1, a closet, which is a space in which a subject does not stay, and an entrance, a corridor, a toilet, and a washroom, which are spaces in which the subject stays for less than a predetermined time, are treated as spaces other than a room. Note that the above is merely an example of this embodiment, and for example, an entrance, a corridor, a toilet, and a washroom may be treated as a room. In the example shown in FIG. 1, the "number of rooms" is a total of four: living / dining / kitchen area, Western-style room 1, Western-style room 2, and a bathroom.

[0028] The "floor plan" refers to the horizontal positional relationship between the rooms and spaces other than the rooms. In the example shown in Figure 1, it refers to the horizontal positional relationship between the rooms, the living / dining / kitchen area, the Western-style room 1, the Western-style room 2, and the bathroom, as well as the spaces other than the rooms, the entrance, the corridor, the toilet, the washroom, and the closet. The "shape of the room" refers to the shape of each room when each floor of the house is viewed from above, as shown in FIG. 1, and more specifically, refers to the shape of the walls surrounding each room. In the example shown in FIG. 1, the shapes of the rooms, Western-style room 1, Western-style room 2, and bathroom, are rectangular (square), and the living / dining room and dining room are protruding toward the Western-style room 2 side (the right side in the figure) compared to the kitchen space. As another example, in the example shown in FIG. 6 and FIG. 7, the shape of the living / dining room and kitchen is L-shaped, and in the example shown in FIG. 8, the shape of the living / dining room and kitchen is a rectangle that is longer in a specific direction (for example, the north-south direction). Note that FIG. 6 and FIG. 7 are the same figure, except that the setting of the sensor installation space S3 described later is different.

[0029] A "partition" includes, for example, a waist-high wall, a screen, a partition, and the like installed in a room. The partition is spaced apart from at least one of the floor, the ceiling, and the wall, and adjacent spaces communicate with each other through the space. A pair of partitions W shown in Fig. 1 separates the space constituting the kitchen from the space constituting the dining and living room in the living-dining-kitchen area. The partitions may be installed in the floor, ceiling, or walls.

[0030] The "number of partitions" is counted as 1 for each partition that divides a space. To explain with reference to FIG. 1, a pair of partitions W separates the space that constitutes the kitchen from the space that constitutes the dining room and living room, so a pair of partitions W is counted as 1. Note that if there is only one partition W instead of a pair of partitions W, for example, if only the right partition W of the pair of partitions W in FIG. 1 is installed in the living / dining / kitchen area, the one partition W is counted as 1 because it separates the space that constitutes the kitchen from the space that constitutes the dining room and living room. "Partition position" means the position of the partition within the room in the horizontal direction. "Space use" refers to the use set for each space in a house, specifically, the use of each of the kitchen, dining room, living room, Western-style room 1, Western-style room 2, bathroom, toilet, washroom, entrance, hallway, and closet, as shown in FIG. 1. A single space use may be set in one room, or multiple space uses may be set in one room. Specifically, as shown in FIG. 1, each of Western-style room 1, Western-style room 2, and bathroom is set to one use, while a combined living / dining / kitchen room is set to three uses: kitchen, dining room, and living room. Space uses are also set for spaces other than rooms, specifically, as shown in FIG. 1, uses are also set for the spaces that make up the entrance, hallway, toilet, washroom, and closet.

[0031] (Regarding the second information) The "second information" is information about the installation conditions of a sensor installed inside a house. "Sensor installation conditions" refers to the sensor specifications and the sensor installation conditions based on the sensor specifications. The "sensor specifications" include the sensor type, sensor application, mounting method, detectable range, and installation environment.

[0032] The "sensor type" refers to a vital sensor, a laser sensor, an infrared sensor, and the like, as described above. As a condition for installing a sensor based on the sensor type, for example, if the sensor type is a vital sensor, it may be recommended to install it in the living room where the subject is often sitting and stationary, and if the sensor type is a laser sensor, it may be recommended to install it in the kitchen where the subject moves around frequently without sitting down. The type of sensor installed inside the house may be determined in advance before this presentation, and for example, all the sensors installed inside the house may be vital sensors.

[0033] As described above, "sensor applications" include, for example, acquiring vital information of a target area of ​​a subject in a house, acquiring position information of the subject, and acquiring posture information of the subject. For example, there is a possibility that sufficient vital sign information cannot be obtained in spaces other than rooms (entrances, corridors, toilets, washrooms, and closets in the example shown in FIG. 1). Therefore, as a condition for installing a sensor based on the sensor's purpose, if the sensor's purpose is to obtain vital sign information, it may be recommended that spaces other than rooms be set as spaces where sensors are not to be installed. Furthermore, if the sensor is installed directly above a position in the room where the subject is likely to be staying, it may not be possible to obtain vital information from the target part (chest, etc.) of the subject. Therefore, as a condition for installing the sensor based on the sensor use, if the sensor use is to obtain vital information, it may be recommended to install the sensor directly above a position in the room where the subject is unlikely to be staying.

[0034] The "mounting method" refers to the method used to mount the sensor to the mounting portion, and specifically includes mounting using screws, magnets, adhesives, and the like. Examples of the "mounting portion" include the base (base material) of a ceiling, wall (interior wall), and floor, as well as studs erected in the base.

[0035] "Detectable range" refers to the maximum range that can be detected by a sensor. In the case of a non-contact sensor, the fewer obstructions there are in the vicinity, the more effectively the sensor's detectable range can be utilized. Therefore, as a sensor installation condition based on the detectable range, it may be recommended to install the sensor in the center of each space or room, for example, in order to maximize the use of the sensor's detectable range.

[0036] The "installation environment" refers to the conditions of the environment in which the sensor is installed, and if these conditions are not met, the sensor may not function properly. Items related to the installation environment include the environmental temperature, the environmental humidity, and the presence of obstructions. The installation environment may include a place (environment) where the installation of the sensor is restricted. For example, the bathroom has a higher environmental temperature and humidity than other rooms in the house. Therefore, as an installation condition of the sensor based on the installation environment, it may be recommended to set the bathroom as a space where the sensor cannot be installed. In addition, the installation conditions of the sensor based on the installation environment may recommend that the sensor be installed at a predetermined distance from the shield so that the shield is not located between the subject and the sensor. In addition, in the case of a non-contact sensor, if the surface material of the shield is, for example, metal, the shield may reflect or absorb electromagnetic waves, laser light, infrared rays, etc., and the sensor may not function normally. Therefore, the installation conditions of the sensor based on the installation environment may recommend that the sensor be installed at a predetermined distance from the shield if the surface of the shield is metal, etc. In addition, examples of "shielding objects" include equipment other than sensors described below, fixtures such as doors and windows, and building materials used for interior decoration.

[0037] (Regarding the third and fourth information) "Third information" refers to information regarding the installation pattern of devices other than sensors inside the home. "Devices other than sensors" include furniture, home appliances, lighting equipment, sensors, kitchen equipment, and the like. "Furniture and home appliances" refers to, for example, dining tables, sofas, televisions, beds, etc., and primarily refers to furniture and home appliances that contribute to identifying the subject's location in daily life. A "lighting device" is something that illuminates a room and is installed on the ceiling of the room. The "detector" detects the outbreak of fire and is installed on the ceiling of the room. "Kitchen equipment" includes a counter, a sink, a stove, and the like, and may be, for example, a system kitchen that integrates these.

[0038] The "installation pattern" is set according to the first information on the internal structure of the house, more specifically, the layout, the shape of the room, the size of the room, or the like.

[0039] Below, two installation patterns will be explained using an example of a combined living / dining / kitchen room with reference to Figures 6 to 8. Representative examples of combined living / dining / kitchen rooms include an L-shape as shown in Figures 6 and 7, and a rectangular shape with the vertical direction as the long axis as shown in Figure 8.

[0040] In the installation patterns shown in Figures 6 and 7, the kitchen equipment is installed in a space that juts out to the right in the figure, with the left-right direction in the figure as its long direction. A dining table is installed in the space to the left of the kitchen equipment, and a living room sofa and television are installed in the space below the space in which the dining table is installed. The dining table may be installed with its long direction facing left and right in the figure (horizontal installation), or with its long direction facing up and down in the figure (vertical installation), and the example shown in Figures 6 and 7 adopts a horizontal installation. The living room television and sofa may be placed facing each other in the left-right direction in the figure (horizontal orientation), or with their long direction facing each other in the up-down direction in the figure (vertical orientation), and the example shown in Figures 6 and 7 adopts a horizontal orientation.

[0041] On the other hand, in the installation pattern shown in Fig. 8, the kitchen equipment is installed in the upper space in the figure so that the vertical direction in the figure is the longitudinal direction. A dining table is installed in the space below the kitchen equipment, and a living room sofa and a TV are installed in the space below the space where the dining table is installed. In the example shown in Fig. 8, the dining table is placed vertically, and the living room TV and sofa are placed horizontally.

[0042] In the example shown in Figure 8, a dining table is installed in the center of the interior space of the house in the left-right direction, and the door located to the right of the dining table is a door that opens and closes toward the outside. If this door were a door that opened and closed toward the inside of the house, the space in the interior space of the house where the door is opened and closed cannot be said to be a space that can be used effectively. Therefore, in this case, the interior space excluding the space where the door is opened and closed can be defined as a usable space, and the dining table can be installed in the center of the usable space in the left-right direction.

[0043] Furthermore, the installation pattern is set according to the fourth information. The "fourth information" is information relating to the conditions of use of the house, specifically, information relating to the construction type, ownership type, and occupants, etc. "Information regarding building type" is information regarding detached houses and collective housing (such as condominiums or apartments). "Information regarding the form of ownership" is information regarding home ownership and rental. "Rental" includes rental for seniors, such as senior housing with services (hereinafter, simply referred to as "senior housing"). "Information about the residents" refers to family structure, and more specifically, information about singles, married couples, child-rearing generations, two-generation households, etc. It also includes information about the number of residents, their gender, age, etc. It also includes information about wheelchair access.

[0044] For example, if the resident is elderly and uses a wheelchair, an installation pattern is set that takes into consideration the traffic flow of the wheelchair. More specifically, in the example shown in Fig. 8, the dining table is installed in the center of the interior space of the house in the left-right direction, and there is not enough traffic flow when accessing the kitchen equipment in a wheelchair. Therefore, for example, an installation pattern in which the dining table is shifted to one side in the left-right direction in the figure may be set according to the fourth information.

[0045] In addition, the example shown in Figure 8 assumes a dining table for four people, but if the resident is a single person living alone, for example, the installation pattern may assume a dining table for two people.

[0046] The installation pattern may be a virtual installation pattern assumed for a fictitious residence, or may be an installation pattern adopted in an actual residence. That is, the installation pattern indicated by the third information may include an installation pattern used as an actual residence, or an installation pattern adopted in a residence used in the past. In other words, the installation pattern may be set based on the current or past performance regarding the internal structure, architectural form, ownership form, and occupants of the residence.

[0047] (About the outline of this presentation) First, a user who uses the present presentation installs an application program for the present presentation (hereinafter, the present presentation application) in advance on the user terminal. The "user" is, for example, an employee of a construction company (such as a housing manufacturer) that builds the target house. A "user terminal" is a computer used by a user, and specifically includes a desktop or notebook PC (Personal Computer), a smart device such as a smartphone, or a tablet terminal provided to each user by a construction company. A user terminal includes a processor, a memory, a communication interface, an input device, and an output device (display screen).

[0048] After installing the presentation application, the user launches the presentation application and, through a predetermined operation, transitions the display screen of the user terminal to a drawing data selection screen. The user imports drawing data of the target house (e.g., the floor plan of FIG. 1) into the user terminal in advance, and selects the target drawing data on the drawing data selection screen. The user may import the target drawing data into the user terminal through a drawing data storage server in the company, for example, or may scan a paper drawing with a scanner and import it into the user terminal as drawing data.

[0049] When the drawing data is selected, the selected drawing data is transmitted to the information processing device 10 described later. The information processing device 10 acquires first information from the transmitted drawing data. More specifically, the information processing device 10 acquires first information such as the number of rooms, layout, shape of the rooms, number of partitions in the rooms, positions of the partitions, and space use from the drawing data using known image analysis technology, object detection technology, and the like. If the first information is insufficient, the display screen of the user terminal may be transitioned to a display screen for inputting the insufficient first information, and the user may be prompted to input the insufficient first information. As a method for inputting the insufficient first information, for example, corrected drawing data may be transmitted.

[0050] When the first information is acquired, second information on the installation conditions of the sensor is acquired from the database server 11 described later. Then, as shown in Fig. 2, a space S1 where the sensor is not installed and a space S2 where the sensor cannot be installed are set for the floor plan indicated by the first information. More specifically, a closet, which is a space where the subject does not stay, and a hallway, a corridor, a toilet, and a washroom, which are spaces where the subject stays for less than a predetermined time, are each set as the space S1 where the sensor is not installed. In addition, a bathroom, which has a higher environmental temperature and humidity than the surrounding rooms or spaces, is set as the space S2 where the sensor cannot be installed.

[0051] Next, based on the layout, room shape, and partition position of the interior of the house indicated by the first information, and the space S1 and space S2 indicated by the second information, one or more sensor installation spaces S3 are set as shown in Fig. 2. More specifically, first, an interior space excluding spaces S1 and S2 is set for the layout of the interior of the house. Then, based on the shape of the room and the position of the partition, the interior space is divided into one or more spaces, and each divided space is set as a sensor installation space S3.

[0052] More specifically, if the room is rectangular and there is no partition within the room, one sensor installation space S3 is set in the room. In the example shown in Fig. 2, the Western-style room 1 and the Western-style room 2 are each rectangular and there is no partition within the room, so one sensor installation space S3 is set. Similarly, in the example shown in Fig. 8, the combined living / dining / kitchen room is rectangular and there is no partition within the room, so one sensor installation space S3 is set. Note that the "rectangle" does not have to be a strict rectangle (quadrangle).

[0053] Furthermore, if the room is rectangular and has partitions within it, each rectangular space separated by the partitions is set as the sensor installation space S3.

[0054] On the other hand, if the shape of the room is not rectangular and there is no partition within the room, multiple rectangular spaces are set within the room, and each of the set rectangular spaces is set as the sensor installation space S3. For example, if the shape of the room is L-shaped and there is no partition within the room, one of the short side or long side of the L shape and the other part excluding the overlapping part of the short side and the long side (i.e., the corner part) are set as a rectangular space. To explain this in detail using the examples shown in Figs. 6 and 7, the shape of the combined living / dining / kitchen room shown in Figs. 6 and 7 is L-shaped, not rectangular, and there is no partition in the room. In this case, as shown in Fig. 6, a rectangular space is set in each of the spaces forming the kitchen and dining room and the space forming the living room, and the rectangular space is set as the sensor installation space S3. Alternatively, as shown in Fig. 7, a rectangular space is set in each of the spaces forming the kitchen and the spaces forming the dining room and living room, and the rectangular space is set as the sensor installation space S3. It is arbitrary which of the setting methods shown in Figs. 6 and 7 is used, but for example, spaces that are more related to each other may be set as one rectangular space based on the space use indicated by the first information. For example, when the space forming the dining room is set to be more related to the space forming the kitchen than the space forming the living room, the setting method of the sensor installation space S3 shown in Fig. 6 is selected.

[0055] In addition, if the shape of the room is not rectangular and there are partitions within the room, the room is first divided into multiple spaces by the partitions, and if each of the divided spaces is a rectangular space, the rectangular space is set as the sensor installation space S3. To explain this in more detail using the example shown in Fig. 2, the shape of the combined living / dining / kitchen room shown in Fig. 2 is not rectangular and there are a pair of partitions W inside the room, so first, the room is divided into a space constituting the kitchen and a space constituting the dining / living room by the pair of partitions W. Since each of the divided spaces is a rectangular space, the rectangular spaces are each set as the sensor installation space S3. If each partitioned space is not a rectangular space, a plurality of rectangular spaces are further defined within each space, and each of the defined rectangular spaces is set as the sensor installation space S3.

[0056] Next, the number of sensors to be installed in the sensor installation space is set according to the relationship between the size (range) of the set sensor installation space S3 and the range in which the sensor can detect, which is indicated by the second information. More specifically, if the range that the sensor can detect is R1, the number of sensors is N (N is a natural number greater than or equal to 1), and the range of the sensor installation space S3 is R2, then N is set so as to satisfy R1×N≧R2. In the example shown in FIG. 3, the number of sensors N is one for each of the sensor installation spaces S3 of the kitchen, Western-style room 1, and Western-style room 2, and a plurality of sensors (two sensors) are set in the sensor installation space S3 that constitutes the dining room and living room.

[0057] Next, when multiple sensors are set in the sensor installation space S3, spaces S4 corresponding to the number of sensors are set in the sensor installation space S3. The spaces S4 are obtained by dividing the sensor installation space S3 into spaces the same number as the number of sensors. In the example shown in FIG. 3, two sensors are set in the sensor installation space S3 that constitutes the dining room and living room, and therefore two spaces S4 are set in the sensor installation space S3. The positions of the two spaces S4 may be set according to the spatial use indicated by the first information, for example. In the example shown in Fig. 3, the dining room space and the living room space are located next to each other in the vertical direction in the figure, so the positions of the two spaces S4 may be set to be next to each other in the vertical direction in the figure according to the spatial use.

[0058] 8, one sensor installation space S3 is set in a combined living / dining / kitchen room, and the number of sensors is set to two. Two spaces S4 set according to the number of sensors may be set to be aligned vertically in the figure according to the use of the space. In this case, spaces that are more closely related to each other may be set as space S4. For example, if the space constituting the dining room is set to be more closely related to the space constituting the kitchen than to the space constituting the living room, the space constituting the kitchen and dining room may be set as one space S4, and the space constituting the living room may be set as the other space S4, as shown in Figure 8.

[0059] After the number of sensors, the sensor installation space S3, and the space S4 corresponding to the number of sensors are set, the information processing device 10 notifies the user terminal to prompt input of the use conditions of the house. That is, an input screen for inputting the use conditions of the house is displayed on the display screen of the user terminal. The user inputs the use conditions of the house according to the instructions on the input screen. As described above, the use conditions of the house include the building type (detached house, apartment house, etc.), the ownership type (owner-occupied house, rented house, etc.), and the occupants (family composition, etc.). When the user finishes inputting, the input information is transmitted from the user terminal to the information processing device 10. As a result, fourth information on the use conditions of the house is acquired. Then, third information indicating the installation pattern of devices other than the sensors is acquired from the database server 11 according to the fourth information. As described above, the devices other than the sensors include furniture, home appliances, lighting devices, sensors, and kitchen equipment.

[0060] Next, based on one or more installation pattern candidates indicated by the third information, installation positions D of each device other than the sensor are set for the floor plan (corresponding to FIG. 3) as shown in FIG. 4. Note that, although not shown in FIG. 4, all areas indicated by dot patterns are installation positions D. The installation positions D for the floor plan differ for each installation pattern candidate. As an example, in the first candidate, as shown in FIG. 4, a dining table installed in a space forming a dining room may be positioned on the left side of space S4 in FIG. 4, and in the second candidate, the dining table may be positioned in the center of space S4 in the left-right direction in FIG. 4.

[0061] Thereafter, a presentation image (image corresponding to FIG. 4) of the installation position D is transmitted from the information processing device 10 to the user terminal according to the number of installation pattern candidates, and is displayed on the display screen of the user terminal. The user selects one or more desired installation patterns from each candidate. When an installation pattern is selected by the user, the selected one or more installation patterns are accepted.

[0062] In the above example, each candidate installation pattern is displayed on the display screen of the user terminal to allow the user to select a desired installation pattern. However, this is not limited to this, and for example, the installation position P of the sensor described later may be set for all the candidate installation patterns without allowing the user to select each candidate installation pattern.

[0063] After one or more installation patterns are received, as shown in FIG. 5, sensor installation positions P are set in the sensor installation space S3 and in each of the spaces S4 according to the number of sensors. For example, first, based on the installation positions D of each device other than the sensor, the area in the room other than the area where the installation positions D are set is set as the range where the subject is likely to stay. Next, based on the sensor installation conditions indicated by the second information, the sensor installation positions P are set in each of the sensor installation spaces S3 and S4 so as to be near the center of each of the sensor installation space S3 and the space S4 according to the number of sensors, while avoiding the area in the room where the subject is likely to stay.

[0064] Furthermore, when devices other than the sensor, fittings such as doors and windows, and building materials used in the interior can be obstructions, the sensor installation position P is set at a position that is a predetermined distance away from the obstructions. Specifically, since lighting devices and detectors are located on the ceiling, when the sensor is installed on the ceiling, the sensor installation position P is set at a position that does not at least physically interfere with the devices. Furthermore, when the surface material of devices other than the sensor, fittings such as doors and windows, and building materials used in the interior is, for example, metal, the electromagnetic waves, laser light, infrared rays, etc. are reflected or absorbed, and the sensor may not function normally. Therefore, when these obstructions have a metal surface, the sensor installation position P is set at a position that is a predetermined distance away from the obstruction.

[0065] When the sensor installation positions P are set in the sensor installation space S3 and in each of the spaces S4 corresponding to the number of sensors, a presentation image of the installation positions P (an image corresponding to FIG. 5) is transmitted to the user terminal. As a result, the presentation image of the installation positions P is displayed on the display screen of the user terminal. In other words, the set sensor installation positions P are presented. The user can decide the actual sensor installation positions while referring to the sensor installation positions presented on the display screen. The presentation image of the installation position P is created for each installation pattern of devices other than the sensor selected by the user, and is transmitted to the user terminal.

[0066] <<Configuration of the sensor installation position presentation system according to this embodiment>> The configuration of a presentation system for sensor installation positions including an information processing device according to this embodiment (hereinafter, referred to as "presentation system A") will be described with reference to FIG.

[0073] As described above, the user terminal 100 is a computer used by a user, and includes a processor, a memory, and a communication interface.

[0074] The database server 11 is included in a cloud-type server prepared by a company (such as a home builder) that provides the service presented herein, in other words, the cloud-type server also serves as the database server 11.

[0075] Second information on sensor installation conditions and third information on installation patterns of devices other than the sensors are stored in the database server 11. The database server 11 may also serve as a plan data storage server for storing plan data of a target house.

[0076] <<Function of the sensor installation position according to this embodiment>> Next, the configuration of the information processing device 10 according to this embodiment will be described again from the functional aspect. The information processing device 10 has a first acquisition unit 31, a second acquisition unit 32, a third acquisition unit 33, a fourth acquisition unit 34, a sensor installation space setting unit 35 (corresponding to a second setting unit), a setting unit 36 ​​(corresponding to a first setting unit), and a presentation unit 41, as shown in FIG.

The recommended sensor installation positions are the center of the sensor installation space S3 and the space S4 according to the number of sensors, as shown in Fig. 5. The sensor installation positions that are not recommended are, for example, directly above a position in the room where the subject is likely to be staying (such as the top of the subject's head), and a position less than a predetermined distance from obstructions (devices other than sensors, fixtures such as doors and windows, and building materials used for interior decoration).

[0079] (3rd acquisition part) The third acquisition unit 33 acquires third information on an installation pattern of devices other than the sensor inside the house.

Then, based on the shape of the room and the position of the partition indicated by the first information, the interior space is divided into one or more spaces, and each divided space is set as a sensor installation space S3.

[0082] (Settings section) The setting unit 36 ​​(corresponding to the first setting unit) sets the installation position of the sensor inside the house based on the first information, the second information, the third information, and the fourth information so as to be a position that satisfies the installation conditions of the sensor and is based on the installation pattern of equipment other than the sensor. More specifically, the setting unit 36 ​​includes a sensor number setting unit 37, an installation pattern candidate setting unit 38, an installation pattern setting unit 39, and a sensor installation position setting unit 40, and the installation positions of the sensors within the house are set by these functions.

More specifically, the sensor number setting unit 37 sets the number of sensors to be installed in the sensor installation space S3 according to the relationship between the size (range) of the sensor installation space S3 set by the sensor installation space setting unit 35 and the range in which the sensor can be detected indicated by the second information. Furthermore, when a plurality of sensors are installed in the sensor installation space S3, the sensor number setting unit 37 sets a space S4 in accordance with the number of sensors for the sensor installation space S3. The position of the space S4 in the sensor installation space S3 according to the number of sensors may be set according to the space use, as described above. In other words, the sensor number setting unit 37 may set the position of the space S4 in the sensor installation space S3 according to the number of sensors in accordance with the space use.

[0084] [Installation pattern candidate setting section] The installation pattern candidate setting unit 38 sets the installation positions D of each device other than the sensor with respect to the floor plan (corresponding to FIG. 3) as shown in FIG. 4 based on one or more installation pattern candidates indicated by the third information. As described above, the installation positions D with respect to the floor plan differ for each installation pattern candidate.

As a result, the presentation image of the installation position P is displayed on the display screen of the user terminal.

[0088] <<About the Presentation Flow According to the Present Embodiment>> Next, a description will be given of the present presentation flow, which is a data processing flow using the above-mentioned information processing device 10. The present presentation flow employs the sensor installation position presentation method of the present invention, and proceeds along the flow shown in Fig. 11. In other words, each step in the flow shown in Fig. 11 corresponds to each element constituting the sensor installation position presentation method of the present invention. It should be noted that the flow shown in FIG. 11 is merely an example, and new steps may be added or the order of steps may be changed without departing from the spirit of the present invention.

[0089] This presentation flow is started when drawing data such as a floor plan of a house to be presented is transmitted from the user terminal 100 to the information processing device 10. In the example shown in this presentation flow, the type of sensor to be installed inside the house is set in advance, for example, a vital sensor.

[0090] The processor 21 acquires first information such as the number of rooms, layout, shape of the rooms, number of partitions in the rooms, positions of the partitions, and spatial use from the drawing data transmitted from the user terminal 100 using known image analysis technology, object detection technology, and the like (S001). Next, the processor 21 determines whether the first information is insufficient (S002). If the processor 21 determines that the first information is insufficient, it notifies the user terminal 100 of the insufficient first information and accepts information input by the user regarding the insufficient first information (S003).

[0091] After acquiring the first information, the processor 21 acquires second information on the installation conditions of the sensor to be installed inside the house from the database server 11 (S004). More specifically, the processor 21 acquires, as the information on the installation conditions, information on the space S1 (see FIG. 2) where the sensor is not installed, the space S2 (see FIG. 2) where the sensor cannot be installed, the detectable range of the sensor, the recommended installation position of the sensor, and the non-recommended installation position of the sensor, as described above.

[0092] After acquiring the second information, the processor 21 sets the sensor installation space S3 as shown in Fig. 2 based on the layout of the interior of the house, the shape of the rooms, and the positions of the partitions indicated by the first information, and the spaces S1 and S2 indicated by the second information (S005). More specifically, the processor 21 sets the interior space excluding the spaces S1 and S2 indicated by the second information for the layout of the interior of the house indicated by the first information. Then, the processor 21 divides the interior space into one or more spaces based on the shapes of the rooms and the positions of the partitions indicated by the first information, and sets each divided space as the sensor installation space S3.

[0093] Next, the processor 21 sets the number of sensors to be installed in the sensor installation space S3 according to the relationship between the size (range) of the sensor installation space S3 and the range in which the sensor can detect, which is indicated by the second information (S007). Thereafter, the processor 21 sets the positions of the space S4 according to the number of sensors in the sensor installation space S3 in accordance with the space use (S008).

[0094] Next, the processor 21 acquires fourth information on the use conditions of the house from the user terminal 100 (S009). More specifically, the processor 21 acquires information on the use conditions of the house transmitted from the user terminal 100 as the fourth information. As described above, the fourth information is information on the construction form, ownership form, resident, etc. Next, the processor 21 acquires third information on an installation pattern of devices other than the sensor inside the house from the database server 11 (S010). As described above, the installation pattern is set according to the first information on the structure inside the house and the fourth information on the use conditions of the house.

[0095] Next, the processor 21 sets one or more installation pattern candidates based on the third information indicating the installation pattern (S011). In the example of this presentation flow, the processor 21 sets, for example, three installation pattern candidates. Therefore, for each of the three installation pattern candidates, the processor 21 sets the installation position D of each device other than the sensor as shown in FIG. 4 for the floor plan indicated by the first information (corresponding to FIG. 3).

[0096] Thereafter, the processor 21 transmits a presentation image of the installation position D of each candidate of the installation pattern to the user terminal 100, and accepts one or more installation patterns selected by the user (S012). In this example of the presentation flow, it is assumed that two installation patterns are selected by the user out of three candidates of the installation pattern.

[0097] Next, the processor 21 sets the installation position P of the sensor so as to be a position that satisfies the sensor installation condition indicated by the second information and is based on the installation pattern set by the installation pattern setting unit 39 (S013). More specifically, the processor 21 sets the installation position P of each sensor based on information on the recommended sensor installation positions and non-recommended sensor installation positions indicated by the second information, and the installation position D shown in Fig. 4 set by the installation pattern setting unit 39. Note that in this example of the presentation flow, since two installation patterns are selected by the user, the processor 21 sets the installation position P of the sensor for each selected installation pattern.

[0098] Next, the processor 21 presents the set installation position P of the sensor (S014). More specifically, the processor 21 transmits a presentation image of the installation position P to the user terminal 100. As a result, the presentation image of the installation position P is displayed on the display screen of the user terminal 100. Note that in this example of the presentation flow, since two installation patterns are selected by the user, the processor 21 transmits two presentation images having different installation positions P of the sensor to the user terminal 100.

[0099] When the above series of processes are completed, the presentation flow ends. In this embodiment, the process is repeated every time the presentation is performed.

[0100] <<Effectiveness of this embodiment>> As described above, in the information processing device 10, the sensor installation position is set based on the first information, the second information, and the third information, and therefore an appropriate sensor installation position P is presented as shown in Fig. 5. As a result, an appropriate sensor installation position can be determined according to the structure of the house, the usage situation, etc. In other words, an installation location that allows the sensor to function well can be determined based on the constraints on sensor installation due to the structure of the house, the usage situation, etc., and the characteristics of the sensor itself, etc. In addition, this also reduces the amount of work required to determine the installation positions of the sensors. Furthermore, when the positions of the substrates on the ceiling, wall (interior wall), and floor vary depending on the installation position of the sensor, this presentation can be used when determining the positions of the substrates.

[0101] In addition, the setting unit 36 ​​sets the number of sensors to be installed inside the house based on the range in which the sensors indicated by the second information can detect, and sets the installation positions P of each of the set number of sensors based on the first information, the second information, and the third information. With the above configuration, the number of sensors to be installed in the house is set based on the range that the sensors can detect, and the installation positions of each sensor are set according to the number of sensors, so that an appropriate sensor installation position P is presented for each sensor. As a result, an appropriate sensor installation position can be determined for each sensor according to the structure of the house, the usage situation, etc.

[0102] In addition, the setting unit 36 ​​sets the number of sensors to be installed inside the house based on at least one of the number of rooms inside the house and the number of partitions in the rooms indicated by the first information, and sets the installation positions of each of the set number of sensors based on the first information, the second information, and the third information. With the above configuration, the number of sensors to be installed in the house is set based on at least one of the number of rooms in the house and the number of partitions in the rooms, and the installation positions of each sensor are set according to the number of sensors, so that an appropriate sensor installation position P is presented for each sensor. As a result, an appropriate sensor installation position can be determined for each sensor according to the structure of the house, the usage situation, etc.

[0103] The information processing device 10 also includes a sensor installation space setting unit 35 that sets a sensor installation space S3 inside the house based on at least one of the layout of the interior of the house, the shape of the rooms, and the positions of the partitions indicated by the first information. The setting unit 36 ​​sets the number of sensors to be installed in the sensor installation space S3 according to the relationship between the size of the sensor installation space S3 and the range in which the sensor can detect indicated by the second information. With the above configuration, the number of sensors to be installed in the house is set according to the relationship between the size of the sensor installation space S3 and the range in which the sensor can detect indicated by the second information, and the installation position of each sensor is set according to the number of sensors, so that an appropriate sensor installation position P is presented for each sensor. As a result, it is possible to determine an appropriate sensor installation position for each sensor according to the structure and usage situation of the house, etc.

[0104] Furthermore, as shown in FIG. 2, the sensor installation space setting unit 35 sets a sensor installation space S3 based on the information of the space S2 in which the sensor cannot be installed, which is indicated by the second information. With the above configuration, the sensor installation position is set based on the sensor installation space S3 that takes into account the space S2 in which the sensor cannot be installed, and therefore a more appropriate sensor installation position P is presented. As a result, a more appropriate sensor installation position can be determined according to the structure and usage conditions of the house.

[0105] The information processing device 10 also includes a third acquisition unit 33 that acquires fourth information related to the use conditions of the house. The setting unit 36 ​​sets the installation positions of the sensors based on the first information, the second information, the third information, and the fourth information. With the above configuration, the sensor installation position is set based on the usage conditions including the house's architectural form, ownership form, and occupancy, and therefore a more appropriate sensor installation position P is presented. As a result, a more appropriate sensor installation position can be determined by taking into account the above-mentioned usage conditions of the house.

[0106] Furthermore, the third acquisition unit 33 acquires third information indicating an installation pattern to be set in accordance with the fourth information, and the setting unit 36 ​​sets the installation positions of the sensors based on the third information. With the above configuration, the sensor installation position is set based on the installation pattern set according to the fourth information, and therefore a more appropriate sensor installation position P is presented. As a result, a more appropriate sensor installation position can be determined according to the structure and usage conditions of the house, etc.

[0107] The third information is information regarding an installation pattern adopted in a building that is actually being used as a residence or has been used in the past. With the above configuration, the sensor installation position is set based on the installation pattern that has actually been adopted, and therefore a more appropriate sensor installation position P is presented. As a result, a more appropriate sensor installation position can be determined according to the structure of the house, the usage situation, etc.

[0108] <<Other embodiments>> Although one embodiment of the information processing device and the method for presenting the sensor installation position of the present invention has been described above, the above embodiment is merely an example for facilitating understanding of the present invention and does not limit the present invention. In other words, the present invention may be modified or improved without departing from the spirit of the present invention. In addition, the present invention naturally includes its equivalents.
