Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a property proposal system that is an embodiment of the present invention. The property proposal system of this embodiment proposes properties with floor plans that will improve the user's life based on the usage status of the user 1's current residence, the surrounding sound situation, the user's degree of relaxation in response to this, etc. This is what I am trying to do.

This property proposal system includes a biometric information acquisition section 21, a position information acquisition section 22, a surrounding situation acquisition section 23, a property proposal device 3, and an input/output terminal 4.

The biometric information acquisition unit 21 includes a heartbeat sensor and the like that measures the user's heartbeat as biometric information. The biological information acquisition unit 21 has a heart rate sensor or the like attached to the body of the user 1 and directly acquires the user's information. The location information acquisition unit 22 acquires location information within the user's residence. The surrounding situation acquisition unit 23 is a sound sensor or the like that collects sounds around the user, and collects sounds that are noise to the user. The position information acquisition unit 22 and the surrounding situation acquisition unit 23 may be attached to the user as a position sensor or a sound sensor, or may be installed in the user's residence to detect the user's position and surrounding sounds. It may also be something that detects. For example, as a position sensor, a video camera may be used to image the user 1 and analyze which room in the residence the user is in, or the user may carry a transmitter and obtain the user's position using a fixed receiver. It can be anything. Further, the surrounding situation acquisition unit 23 may obtain sounds around the user 1 using a microphone in the living room.

The property proposal device 3 is an information processing device built on a server. The property proposal device 3 can also be configured as a cloud. The property proposal device 3 includes a user information storage section 31, a relaxation information calculation section 32, a property information holding section 33, and a property information extraction section 34. The user information storage unit 31 stores real estate information such as the floor plan of the residence where the user currently resides, its area, frontage dimensions, family composition, size and purpose of each room, whether the residence faces the road, etc. It remembers information about its surroundings. The user information storage unit 31 stores the user's biometric information acquired by the biometric information acquisition unit 21, the user's position information acquired by the position information acquisition unit 22, and the user's position information acquired by the surrounding situation acquisition unit 23, which are associated with each other. Stores sound information around the user. Below, the user's biometric information acquired by the biometric information acquisition unit 21, the user's position information acquired by the position information acquisition unit 22, and the user's surrounding information acquired by the surrounding situation acquisition unit 23 are described below. The sound information is appropriately referred to as user relaxation information.

The relaxation information calculation unit 32 calculates the degree of relaxation of the user from the user's relaxation information acquired by the biological information acquisition unit 21, the position information acquisition unit 22, and the surrounding situation acquisition unit 23. The property information holding unit 33 holds information on properties with proposed floor plans. The property information extraction unit 34 extracts a property with a floor plan to be presented to the user based on the degree of relaxation of the user calculated by the relaxation information calculation unit 32 from the property information holding unit 33 and presents it to the user via the input/output terminal 4. do.

The input/output terminal 4 is an input/output device connected to the property proposal device 3 via the network 5 (FIG. 2). The property information such as the floor plan of the user's current residence, the user's family information such as the family structure, information about the surroundings of the residence, etc. input by the user via the input/output terminal 4 are provided to the property proposal device 3. , is stored in the user information storage section 31 as user information. Additionally, information such as the floor plan of the property extracted by the property information extraction unit 34 of the property proposal device 3 is output and displayed. The input/output terminal 4 can be realized by, for example, a computer, a smartphone, a tablet terminal, or the like. Further, the input/output terminal 4 may have the function of the property proposal device 3 inside the terminal.

Referring to FIG. 2, a mode of acquiring relaxation information at the current residence of the user 1 will be described. When the property proposal device 3 acquires the relaxation information of the user 1 who is spending time in the residence acquired by the biometric information acquisition section 21, the position information acquisition section 22, and the surrounding situation acquisition section 23 via the network 5, the property proposal device 3 stores the user information in the user information storage. The information is stored in the section 31. The property proposal device 3 calculates the user's degree of relaxation in the current residence based on the relaxation information, and selects from the property information holding unit 33 properties with a floor plan that increases the user's degree of relaxation in accordance with the degree of relaxation. Prioritize and propose.

Here, based on the relationship between the user's degree of relaxation, noise, and floor plan, what kind of floor plan and equipment should be prioritized to increase the degree of relaxation will be explained.
First, it is known that stress levels can be measured from heart rate variability. If the L/T (L: The length of the Longitudinal axis, T: The length of the Transverse axis) of the heartbeat waveform is large, the person is at rest and relaxed, and the smaller the L/T is, the more the person is in a state of stress or tension. It is known that there is. In this way, the degree of relaxation of the user can be measured by using information on the heart rate and heart rate variability from the heart rate sensor. It is also known that people become less relaxed when exposed to loud noises.

Further, from the user's location information, it is possible to know the noise level and degree of relaxation in a certain room at a certain time. From this, the user can know the time, time, and room where the degree of relaxation is less than or equal to a predetermined threshold. The threshold for the degree of relaxation may be arbitrarily determined in advance, or may be a value that can be used to determine that a generally relaxed state has been impaired. It can also detect the time of day, the time of day, and the level and type of noise in the room.

If the noise that occurs when the degree of relaxation is low comes into the room from outside, such as the sound of a car running, the room should be located far from the outside road or have a floor plan with external soundproofing equipment. do it.
Furthermore, if the type of noise is the sound from an adjacent room, the relevant room may be located far from the adjacent room, or the floor plan may include soundproofing equipment on the adjacent wall.
Furthermore, if a user who is in the living room becomes less relaxed due to the noise coming from an adjacent child's room at night, the user may decide not to place the child's room causing the noise adjacent to the living room, or to create a hallway between the child's room and the child's room. It is possible to take measures such as changing the floor plan to improve the soundproofing of the walls between the rooms.
Furthermore, if the user is active at night, it is effective to create a floor plan that shortens the line of flow between the user's room and the living room so that the user does not disturb others during the night.
Measures to deal with the above-mentioned noise include moving the room away from the noise source, locating the room on an upper floor, soundproofing the wall between the noise source and reducing the placement and number of windows between the noise source and the noise source. - Measures such as adjusting the size and using soundproof glass are effective. Measures such as moving the door away from the noise source and placing a corridor between it and the noise source are also effective.
When the degree of relaxation is low as in the above, it is possible to preferentially extract properties with floor plans that take measures such as arranging rooms away from noise sources and installing soundproof equipment.

The property proposal process of the property proposal device 3 will be explained with reference to the flowchart of FIG.
FIG. 3 is a flowchart of a property extraction process performed for noise when the user is not relaxing (non-relaxing noise) as an example of the property extraction process.

The property information holding unit 33 stores various types of property information through prior registration processing and the like.
The user information storage unit 31 stores information on the floor plan of the user's current residence, its area, frontage dimensions, the size of each room, the purpose of each room, family structure, and road facing information through a prior registration process, etc. Information on the user's property necessary for property proposals, such as information on the surrounding situation of the residence, such as dolphins, is recorded. The user information storage unit 31 also stores relaxation information acquired by the biometric information acquisition unit 21, position information acquisition unit 22, and surrounding situation acquisition unit 23 started by the user's operation on the input/output terminal 4, and relaxation information calculation. The degrees of relaxation calculated by the unit 32 are stored in association with each other.

In step S11, the property information extraction unit 34 of the property proposal device 3 acquires the degree of relaxation of the user stored in the user information storage unit 31, and determines the time and time (non-relaxation time・Extract time). Then, in step S12, the property information extraction unit 34 detects the user's position at the non-relaxation time/time from the user's relaxation information. Further, in step S13, the property information extraction unit 34 detects the loudness and type of sound (non-relaxing noise) at the non-relaxing time/time from the user's relaxation information.

Then, in step S14, the property information extraction unit 34 determines whether the non-relaxing noise comes from outdoors or indoors. This judgment is made based on the type of sound. If the non-relaxing noise is the sound of a vehicle, it is from outside. Conversely, if the noise is made by the user's family, it is indoors. Furthermore, since the sound sensor can detect the direction from which the sound is coming, it is possible to determine whether the sound is outdoors or indoors.

If the non-relaxing noise is outdoors, in step S15, the property information extraction unit 34 extracts the layout of the corresponding room, preferentially extracting a property that is located far from the noise source or has soundproofing equipment outside. In step S16, the property information extraction unit 34 presents the extracted property information to the user via the input/output terminal 4.

If the non-relaxation noise is indoors, in step S17, the property information extraction unit 34 detects the room that caused non-relaxation (non-relaxation-causing room) next to the room that was in the non-relaxation time (non-relaxation room). do. The property information extraction unit 34 preferentially extracts rooms that have the same purpose as the non-relaxation-causing room and are separated from each other, or properties that have soundproof equipment such as a hallway between them. For example, if the non-relaxing room is the living room and the non-relaxing room is the child's room, it is not necessary to have them adjacent to each other; either they are separated by a hallway, or the wall between the child's room and the child's room should be made soundproof. All you have to do is extract the properties that have been found. This extracted property is presented to the user's input/output terminal 4 in step S16.

Changes in the degree of relaxation of the user when non-relaxing noise is detected can also be calculated. For example, since the degree of stress can be measured by variations in the heartbeat cycle, corresponding variations in the degree of relaxation can also be detected. It can also be seen that the degree of relaxation decreased due to an increase in heart rate. Then, changes in the degree of relaxation at the time corresponding to the timing at which non-relaxing noise is detected are also detected, and the floor plan is set to a position where the non-relaxing noise is reduced, or the non-relaxing noise is reduced in order of decreasing degree of relaxation. It is also possible to preferentially extract and present properties with floor plans equipped with soundproofing equipment.

In the above embodiment, heartbeat information is used as biometric information to detect the user's degree of relaxation, but other biometric information may also be used. Humans respond to stress with physiological information such as heartbeat, pulse, respiration, electrical skin activity, eyeball activity, saliva, and brain waves. As long as the physiological information can be acquired and the degree of relaxation can be calculated, the biological information to be acquired and the type of sensor are not limited. For example, a sensor that is attached to the user's skin and measures changes in skin potential may be used as the biological information acquisition unit 21.

In the above embodiment, an example was explained in which a property with a different floor plan is proposed to the user, but when renovating, it is also possible to propose a new floor plan to the current residence with changes to the floor plan and soundproofing. You can also do it. In this case, it is more preferable that the property information holding unit 33 has a program for renovating the user's current residence as a database.

(Summary of effects)
As described above, the property proposal system includes the biometric information acquisition unit 21 that acquires the biometric information of the user, the location information acquisition unit 22 that acquires the location information in the user's residence, and the data on the surrounding situation of the user. a relaxation information calculation unit 32 that calculates the user's degree of relaxation from the acquired biometric information; a property information holding unit 33 that holds information on properties to be proposed; and a property information extraction unit 34 that extracts properties held by the property information holding unit based on the degree of relaxation at the location in the residence. As a result, it is possible to understand the user's level of relaxation based on the user's location in the residence, the time of day, and the surrounding situation, so it is possible to understand what kind of floor plan the user would find relaxing or stress-free, and to select a property with a floor plan that matches that. can be proposed.

Further, the surrounding situation acquisition unit 23 acquires at least the surrounding sound information at the user's position in the residence, and the property information extraction unit 34 acquires at least the surrounding sound information at the user's position in the residence, and the property information extraction unit 34 extracts the floor plan or surrounding sound information at a position where the acquired surrounding sounds are reduced. Since properties with floor plans equipped with soundproofing equipment that lower the noise level are preferentially extracted, it is possible to suggest properties with floor plans in which the user is less stressed by noise and has a high degree of relaxation.

The biological information acquisition unit 21 acquires the user's heart rate, and the relaxation information calculation unit 32 determines that the degree of relaxation is low if the user's heart rate is high or the fluctuation in the heartbeat cycle is large. Therefore, the user's degree of relaxation can be determined from variations in the heart rate or heartbeat cycle of the user's heartbeat data, the user's degree of relaxation can be measured more accurately, and proposals tailored to the user can be made.

The relaxation information calculation unit 32 records the degree of decrease in the degree of relaxation of the user when the surrounding sounds are loud, and the property information extraction unit 34 records the floor plans in the order of decreasing degree of relaxation, in order of decreasing the degree of relaxation. Alternatively, properties equipped with soundproofing equipment that reduce surrounding noise are prioritized, so if the user's level of relaxation is significantly reduced due to surrounding noise, it is possible to suggest properties with floor plans that reduce surrounding noise. It is possible to improve the quality of life of the user.
