Description

[Technical field]

[0001] The present invention relates to a compatibility determination device that determines the compatibility between two people based on the synchronization rate of their heart rates. [Background technology]

[0002] A method for determining the degree of compatibility between two people in a private room based on the synchronization rate of their heart rates is known as a conventional technique. Compatibility is the degree to which two people are attracted to each other. [Prior art documents] [Non-patent literature]

[0004] However, the above-mentioned conventional technology is carried out in a private room for experiments. Therefore, for example, for those who provide a matching service that introduces people with high compatibility, there is a problem that it is difficult to implement because of the cost of preparing a private room. In this regard, if a commonly used passenger car can be used as the private room, it will be possible to provide a simple and effective matching service.

[0005] One aspect of the present invention aims to realize a compatibility determination device that can diagnose and output the compatibility between any two occupants in a vehicle cabin space based on the synchronization rate of the heartbeats of the occupants. [Means for solving the problem]

[0006] In order to solve the above problems, a compatibility determination device according to one aspect of the present invention includes an input unit that acquires data of simultaneously measured heart rates of two or more occupants who are riding in a space of a moving body, and a compatibility determination unit that determines the compatibility between a first occupant whose first heart rate data is measured and a second occupant whose second heart rate data is measured according to the synchronization rate between the first heart rate data and the second heart rate data among the heart rate data. According to the above configuration, the compatibility between any two occupants in the vehicle interior space can be diagnosed and output based on the synchronization rate of the heart rates of the occupants.

[0007] In order to solve the above problem, in the compatibility determination device according to one aspect of the present invention, the synchronization is a time during which a difference between the first heartbeat data and the second heartbeat data is within a predetermined error range. With this configuration, the compatibility can be calculated with a small amount of calculation.

[0008] In order to solve the above problem, in a compatibility determination device according to one aspect of the present invention, the number of occupants is three or more, and the compatibility determination unit determines the compatibility for each combination of occupants. With the above configuration, it is possible to efficiently determine the compatibility for a large number of people.

[0009] In order to solve the above problem, a compatibility determination method according to one aspect of the present invention includes an input step of acquiring data of simultaneously measured heart rates of two or more passengers who are riding in a space of a moving body, and a compatibility determination step of determining the compatibility between a first passenger whose first heart rate data is measured and a second passenger whose second heart rate data is measured according to the degree of synchronization between the first heart rate data and the second heart rate data among the heart rate data. According to the above configuration, the same effect as that of the compatibility determination device is achieved.

[0010] In order to solve the above problem, in a compatibility determination method according to one aspect of the present invention, the number of occupants is three or more, and the compatibility determination step determines the compatibility for each combination of occupants. With this configuration, it is possible to efficiently determine the compatibility for a large number of people.

[0011] In order to solve the above problem, the compatibility determination method according to one aspect of the present invention further includes a step of identifying a combination having the highest degree of synchronization among the combinations, and further performing the input step and the compatibility determination step only for the occupant corresponding to the identified combination. With the above configuration, it is possible to more accurately and efficiently determine the compatibility.

[0012] In order to solve the above problems, a compatibility determination program for causing a computer to function as the compatibility determination unit according to one aspect of the present invention causes a computer to function as the compatibility determination unit. According to the above configuration, the same effects as those of the compatibility determination device are achieved.

[0013] The compatibility assessment device relating to each aspect of the present invention may be realized by a computer. In this case, the control program of the compatibility assessment device that realizes the compatibility assessment device on a computer by causing the computer to operate as each part (software element) of the compatibility assessment device, and the computer-readable recording medium on which it is recorded, also fall within the scope of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail.

[0017] The compatibility determination device of this embodiment includes an input unit that acquires data on simultaneously measured heart rates of two or more occupants riding in a single space of a moving body, and a compatibility determination unit that determines the compatibility between a first occupant whose first heart rate data is measured and a second occupant whose second heart rate data is measured, depending on the synchronization degree between first heart rate data and second heart rate data among the heart rate data.

[0018] (Configuration of compatibility determination device) 1 is a diagram illustrating an overview of a compatibility determination device 1 according to embodiment 1. The compatibility determination device 1 uses a passenger car 2A as a moving object.

[0019] (Passenger car configuration) The passenger car 2A has two seats, a first seat 211 and a second seat 212. The passenger car 2A may be an autonomous vehicle that does not require a driver, but may have a driver's seat and other seats not shown. The first seat 211 and the second seat 212 are arranged so that passengers seated in each seat can easily talk to each other, and may be facing each other or next to each other.

[0020] (Configuration of each part of the compatibility degree determination device 1) The compatibility determination device 1 has an input unit 110, a control unit 120, a storage unit 130, and an output unit 140. The compatibility determination device 1 first acquires data necessary for compatibility determination from the input unit 110, then performs compatibility determination in the control unit 120, and finally stores the determination result in the storage unit 130 and outputs the determination result from the output unit 140. Note that the compatibility determination device 1 may be configured such that the control unit 120 and the storage unit 130 are provided outside the passenger car 2A, and the external control unit 120 can communicate with the input unit 110 and the output unit 140 inside the passenger car 2A.

[0021] (Input section configuration) The input unit 110 has a first heart rate monitor 111 and a second heart rate monitor 112. The first heart rate monitor 111 and the second heart rate monitor 112 may be, for example, piezoelectric sensors. The first heart rate monitor 111 is installed in the first seat 211 and acquires first heart rate data D1 of a first occupant P1 seated in the first seat 211. The second heart rate monitor 112 is installed in the second seat 212 and acquires second heart rate data D2 of a second occupant P2 seated in the second seat 212. The heart rate data is signal data that indicates a transition of the electric potential of the heart in a time series.

[0022] (Control Unit Configuration) The control unit 120 includes a seating state determination unit 121, an event provision unit 122, a heartbeat data selection unit 123, a heartbeat synchronization rate calculation unit 124, a compatibility determination unit 125, and a compatibility determination sheet creation unit 126. The seating state determination unit 121 determines whether or not an occupant is seated in each seat. The seating state determination unit 121 may perform this determination based on heartbeat data acquired from the first heartbeat meter 111 or the second heartbeat meter 112. That is, the seating state determination unit 121 may determine that the first seat 211 is in a seating state when, for example, first heartbeat data D1 from which a synchronization rate can be calculated is detected from the first heartbeat meter 111.

[0023] The event providing unit 122 provides an event by acquiring audio and image data constituting an event from an event storage unit 132 (to be described later) and sequentially outputting the data from an output unit 140. Details of events and the flow of providing events will be described later.

[0024] The heartbeat data selection unit 123 selects two pieces of heartbeat data for determining the degree of compatibility from among the acquired multiple pieces of heartbeat data. In this embodiment, since there are only two pieces of heartbeat data, the first heartbeat data D1 and the second heartbeat data D2, the heartbeat data selection unit 123 selects these pieces of heartbeat data.

[0025] The heartbeat synchronization rate calculation unit 124 calculates the synchronization rate of the two heartbeat data selected by the heartbeat data selection unit 123. The synchronization rate indicates the proportion of the degree to which the two heartbeat data are synchronized within a predetermined measurement time. The synchronization rate may be the proportion of the time during which the difference between the heartbeat data is within a predetermined error range (hereinafter referred to as the synchronization time) within the predetermined measurement time. The synchronization rate may also be calculated by cross-correlation analysis.

[0026] The compatibility determination unit 125 determines the compatibility between the two occupants whose heartbeat data was measured and selected by the heartbeat data selection unit 123, based on the synchronization rate calculated by the heartbeat synchronization rate calculation unit 124. The compatibility may be expressed by a numerical value or by two values, "high" or "low". The compatibility determination unit 125 stores the determination result in the compatibility storage unit 1311.

[0027] The compatibility judgment sheet creation unit 126 creates a compatibility judgment sheet 133 from the compatibility determined by the compatibility determination unit 125 or the contents of the compatibility storage unit 1311, and stores the created compatibility judgment sheet 133 in the storage unit 130. The compatibility judgment sheet 133 is a collection of questions for determining the compatibility between the first occupant P1 and the second occupant P2. The compatibility judgment sheet creation unit 126 creates the compatibility judgment sheet 133 by selecting questions appropriate for determining the compatibility between the first occupant P1 and the second occupant P2. For example, when it is found from the data stored in the compatibility storage unit 1311 that occupants with the same hobby have a tendency to have a high compatibility, the compatibility judgment sheet creation unit 126 adds a question asking about the hobby to the compatibility judgment sheet 133. Similarly, the compatibility judgment sheet creation unit 126 may delete questions that are less related to the compatibility from the compatibility judgment sheet 133.

[0028] (Storage Configuration) The storage unit 130 has a database 131, an event storage unit 132, and a compatibility judgment sheet 133. The database 131 is a collection of information including personal information of the first occupant P1 and the second occupant P2, and includes, for example, the name, sex, academic background, hobbies, attributes of partners with high compatibility, attributes of partners with low compatibility, compatibility judgment usage history, conversation content at the time of compatibility judgment, values, and political party supported by each occupant. The database 131 includes a compatibility storage unit 1311, and the compatibility between occupants is stored in the compatibility storage unit 1311. The database 131 may be on a cloud (not shown) so that information of multiple people can be centrally managed. The event storage unit 132 stores data such as image data and audio data and combinations thereof to provide appropriate topics for communication between the first occupant P1 and the second occupant P2. The compatibility judgment sheet 133 is a collection of questions for judging compatibility. The compatibility assessment sheet 133 includes questions such as, for example, "It is better if the academic background is similar" and "It is better if the sense of money is similar," and each crew member can answer these questions with "applies" or "does not apply." The compatibility assessment sheet 133 may be provided to each crew member in any medium.

[0029] (Output section configuration) The output unit 140 includes a monitor 141, a speaker 142, a first smartphone 1431, and a second smartphone 1432. The output unit 140 may include other output devices (not shown). The monitor 141 may be, for example, a monitor included in the passenger vehicle 2A. The speaker 142 may be, for example, a speaker included in the passenger vehicle 2A.

[0030] The first smartphone 1431 is a smartphone carried by the first occupant P1. The second smartphone 1432 is a smartphone carried by the second occupant P2.

[0031] (Processing Executed by Compatibility Degree Determination Device 1) FIG. 2 is a flowchart showing the overall process executed by the compatibility degree determination device 1. As shown in FIG.

[0032] First, the event providing unit 122 provides an event to the first occupant P1 and the second occupant P2 by acquiring data for the event from the event storage unit 132 and sequentially outputting the data (S110). In the event, a combination of a series of audio data, image data, and the like is reproduced to provide an appropriate topic for the first occupant P1 and the second occupant P2 to communicate with each other. Specifically, the event may, for example, reproduce image data encouraging the first occupant P1 and the second occupant P2 to play a game such as a word chain, or reproduce audio data providing tourist information about the area around the passenger vehicle 2A. The event providing unit 122 may, for example, acquire the hobbies of the first occupant P1 and the second occupant P2 stored in the database 131 and the position information of the passenger vehicle 2A to determine which event to provide.

[0033] During a predetermined time while the event is being provided, the input unit 110 acquires the first heartbeat data D1 of the first occupant P1 from the first heartbeat meter 111 and the second heartbeat data of the second occupant P2 from the second heartbeat meter 112 (S112). The acquisition may be started simultaneously with the start of the provision of the event.

[0034] After a predetermined time has elapsed, the heartbeat synchronization ratio calculation unit 124 calculates the synchronization ratio for the two pieces of heartbeat data (S122). The calculation process of the synchronization ratio will be described later.

[0035] The compatibility degree determination section 125 acquires the synchronization rate calculated by the heartbeat synchronization rate calculation section 124, and determines the compatibility degree according to the synchronization rate (S124). In this embodiment, the compatibility degree is represented by an integer from 1 to 5.

[0036] Next, the compatibility determination unit 125 stores the determined compatibility in the compatibility storage unit 1311 (S126). The structure of the stored data will be described later.

[0037] Next, the compatibility judgment sheet creation unit 126 acquires the determined compatibility and updates the compatibility judgment sheet 133 (S128). If the compatibility judgment sheet 133 has not yet been created, the compatibility judgment sheet creation unit 126 may create a new compatibility judgment sheet 133.

[0038] Finally, the compatibility degree determination unit 125 outputs the determined compatibility degree through the output unit 140 (S130). The output may be an image output through the monitor 141, or a sound output through the speaker 142. The output may also be a transmission of the compatibility degree to each occupant through a screen or notification information of the first smartphone 1431 carried by the first occupant P1 or the second smartphone 1432 carried by the second occupant P2.

[0039] (Synchronization rate calculation process) The synchronization rate calculation process will be described in detail with reference to Fig. 3. Fig. 3 is a graph showing the transition of the first heartbeat data D1 corresponding to the first occupant P1 and the first seat 211, and the second heartbeat data D2 corresponding to the second occupant P2 and the second seat 212. The vertical axis of the graph indicates the cardiac action potential, and the horizontal axis indicates time.

[0040] The synchronization rate may be calculated as the time (hereinafter referred to as synchronization time) during which the potential difference between the first heartbeat data D1 and the second heartbeat data D2 is within a predetermined error range during the time (hereinafter referred to as measurement time) during which the heartbeat data is measured. In this case, if the measurement time is 100 seconds and the synchronization time is 40 seconds, the synchronization rate is 40%. Alternatively, the synchronization rate may be the degree of correlation between the first heartbeat data D1 and the second heartbeat data D2 calculated by cross-correlation analysis.

[0041] (Compatibility saving process) FIG. 4 is a data structure diagram showing a storage state of a compatibility determination result according to the first embodiment. The compatibility storage unit 1311 stores a combination ID, a user ID, a user ID2, a synchronization rate, and a compatibility rate. The combination ID is a unique number that represents a combination of different occupants. The user ID is a number that can identify one occupant of the combination, and is assigned so as to be uniquely determined in the database 131. The user ID2 is a number that can identify the other occupant of the combination, and is assigned so as to be uniquely determined in the database 131. The synchronization rate is the synchronization rate between a specific user ID and the user ID2. The compatibility rate is the compatibility rate between a specific user ID and the user ID2. For the same combination ID, the values ​​of the synchronization rate and the compatibility rate may be overwritten each time a new calculation or determination is performed. Alternatively, the compatibility storage unit 1311 may store a plurality of or all of the past synchronization rates and compatibility rates of the same combination ID. Although not shown, the compatibility storage unit 1311 may further store at least one of the date and time when the synchronization rate was calculated and the date and time when the compatibility rate was determined. In this figure, the synchronization rate of a first occupant P1 with a user ID of 1 and a second occupant P2 with a user ID of 2 is calculated to be 40%, and the compatibility rate is determined to be 2, so that the user ID is stored as 1, the user ID 2 is stored as 2, the synchronization rate is 40, and the compatibility rate is stored as 2 in the row of combination ID1.

[0042] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals are given to members having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0043] (Passenger car configuration) The configuration of the passenger car 2B of this embodiment will be described with reference to FIG. 5. In this embodiment, the passenger car 2B has three or more seats. Here, for convenience of explanation, the case where the number of seats is three will be described. In addition to the configuration of the passenger car 2A, the passenger car 2B has a third seat 213, and a third passenger P3 can be seated therein. The compatibility degree determination device 1 also has a third heart rate meter 113 provided on the third seat 213, and the third heart rate meter 113 acquires third heart rate data D3. The compatibility degree determination device 1 also has a third smartphone 1433 carried by the third passenger P3.

[0044] (Processing Executed by Compatibility Degree Determination Device 1) The process executed by the compatibility degree determination device 1 will be described with reference to Fig. 6. Steps S210 and S212 are similar to steps S110 and S112 in Fig. 2, and therefore description thereof will not be repeated. In addition, the event provided by the event providing unit 122 in step S210 has contents suited to the number of occupants.

[0045] In this case, the input unit 110 acquires three pieces of heartbeat data, the first heartbeat data D1, the second heartbeat data D2, and the third heartbeat data D3, and so there are three combinations of heartbeat data. That is, the control unit 120 repeats steps S220 to S228 three times for all combinations of seats for which heartbeat data exists and in which the person is seated.

[0046] The heartbeat data selection unit 123 selects each heartbeat data for the combination (S220). If the combination to be calculated is the first heartbeat data D1 and the second heartbeat data D2, the heartbeat data selection unit 123 selects the first heartbeat data D1 and the second heartbeat data D2.

[0047] The heartbeat synchronization rate calculation unit 124, the compatibility degree determination unit 125, and the compatibility degree judgment sheet creation unit 126 execute steps S222 to 228 using the two heartbeat data selected by the heartbeat data selection unit 123. Steps S222 to 228 are similar to steps S122 to 128 in FIG. 2, and therefore will not be described repeatedly.

[0048] Finally, the compatibility determination unit 125 outputs the determined compatibility through the output unit 140 (S230). In addition to the case of step 130 in Fig. 2, the output may be a transmission of the compatibility to each occupant through a screen or notification information of the third smartphone 1433 carried by the third occupant P3. Moreover, what is output may be the compatibility of all the determined combinations, or the compatibility of a combination having a higher compatibility than a predetermined reference value among the combinations.

[0049] (Synchronization rate calculation process) The synchronization rate calculation process will be described in detail with reference to Fig. 7. When the number of occupants is three, there are three combinations of heartbeat data: the first heartbeat data D1 and the second heartbeat data D2 (combination ID1), the first heartbeat data D1 and the third heartbeat data D3 (combination ID2), and the second heartbeat data D2 and the third heartbeat data D3 (combination ID3). In step S222, the heartbeat synchronization rate calculation unit 124 calculates, for each combination, the proportion of the synchronization time of both heartbeat data out of the measurement time as the synchronization rate.

[0050] (Compatibility saving process) Fig. 8 is a data structure diagram showing a storage state of the compatibility degree determination result according to the embodiment 2. Each item is the same as that in Fig. 4. It is assumed that a user ID3 is assigned to the third occupant P3.

[0051] The combination ID1 stores the compatibility between a user with ID1 corresponding to the first heartbeat data D1 and a user with ID2 corresponding to the second heartbeat data D2. As a result of calculation and determination by the control unit 120, the synchronization rate of the combination is stored as 40, and the compatibility is stored as 2.

[0052] The combination ID2 stores the compatibility between the user with ID1 corresponding to the first heartbeat data D1 and the user with ID3 corresponding to the third heartbeat data D3. As a result of calculation and determination by the control unit 120, the synchronization rate of the combination is stored as 80, and the compatibility is stored as 4.

[0053] The combination ID3 stores the compatibility between the user with ID2 corresponding to the second heartbeat data D2 and the user with ID3 corresponding to the third heartbeat data D3. As a result of calculation and determination by the control unit 120, the synchronization rate of the combination is stored as 40, and the compatibility is stored as 2.

[0054] As described above, in the compatibility determination device 1, the number of occupants is three or more, and the compatibility determination unit 125 can determine the compatibility for each combination of occupants. This makes it possible to efficiently determine the compatibility for a large number of people.

[0055] [Embodiment 3] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals are given to members having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0056] In this embodiment, it is assumed that a matching service provider performs matching for a large number of users. A matching service is a service that introduces a user to another user who has a high compatibility with the user. Information on each user is stored in the database 131 in advance.

[0057] (Pre-match) Each user answers a separately prepared compatibility assessment sheet 133, and according to the answer, the users are divided into groups according to the number of seats in the passenger car 2B. The grouping may be performed on a smartphone app (not shown) carried by each user. Alternatively, the grouping may be performed using user information stored in the database 131.

[0058] (Matching in multi-seat passenger cars) The overall flow of the process in which the compatibility degree determination device 1 performs matching of the grouped users will be described with reference to Fig. 9. First, the grouped users get into the passenger car 2B similar to that of the second embodiment.

[0059] After getting in, first, the compatibility determination device 1 executes a process for when there are three or more occupants (S200). This process is similar to the process of the compatibility determination device 1 in the second embodiment shown in FIG.

[0060] Next, the heartbeat data selection unit 123 identifies the pair of heartbeat data with the highest compatibility as a result of the process of step S200 (S232). As in Fig. 8, when the compatibility of combination ID1 is determined to be 2, the compatibility of combination ID2 is determined to be 4, and the compatibility of combination ID3 is determined to be 2 as a result of this process, the combination with the highest compatibility is combination ID2, that is, the combination of the first heartbeat data D1 and the third heartbeat data D3. Therefore, in this case, the heartbeat data selection unit 123 identifies the combination of the first heartbeat data D1 and the third heartbeat data D3.

[0061] Next, the control unit 120 identifies two occupants corresponding to the heart rate data (S234). In this case, the control unit 120 identifies a first occupant P1 corresponding to the first heart rate data D1 and a third occupant P3 corresponding to the third heart rate data D3.

[0062] Thereafter, the output unit 140 moves the two identified occupants to a passenger vehicle with two seats, i.e., a passenger vehicle similar to the passenger vehicle 2A of the first embodiment (S300). The process of moving may be, for example, outputting a voice through the speaker 142 to prompt the first occupant P1 and the third occupant P3 to get out of the passenger vehicle 2B and move to the passenger vehicle 2A. The output unit 140 may also cause passengers other than the two identified occupants to get out of the vehicle.

[0063] (Matching in a two-seater car) After getting in, the compatibility determination device 1 executes a process for when there are two occupants (S400). This process is similar to the process of the compatibility determination device 1 in the first embodiment shown in FIG.

[0064] In this way, it is possible to use the compatibility determination device 1 to first determine the compatibility for each combination of occupants in a vehicle with three or more occupants, identify the combination with the highest degree of synchronization among the combinations, and perform the steps of acquiring heart rate data and determining the compatibility for only the occupants corresponding to that combination. According to this embodiment, a matching service can be provided that efficiently introduces people with high compatibility to a large number of users.

[0065] [Modifications] The output unit 140 may include each seat as an output device. For example, when the compatibility determination unit 125 determines that the compatibility between the first occupant P1 and the second occupant P2 is high, the compatibility determination unit 125 may move the first seat 211 and the second seat 212 closer to each other in order to indicate that the compatibility is high. Also, for example, when the compatibility determination unit 125 determines that the compatibility between the first occupant P1 and the second occupant P2 is low, the compatibility determination unit 125 may move the first seat 211 toward the exit on the right side of the passenger vehicle 2A and the second seat 212 toward the exit on the left side of the passenger vehicle 2A in order to encourage each occupant to get off.

[0066] [Software implementation example] The functions of the compatibility determination device 1 (hereinafter referred to as the "device") are realized by a program for causing a computer to function as the device, and by a program for causing a computer to function as each control block of the device (particularly each part included in the control unit 120).

[0067] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program to realize each function described in each of the above embodiments.

[0068] The program may be non-transitory and may be recorded in one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be provided to the device via any wired or wireless transmission medium.

[0069] In addition, some or all of the functions of each of the control blocks can be realized by a logic circuit. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of each of the control blocks can be realized by, for example, a quantum computer.

[0070] Furthermore, each process described in each of the above embodiments may be executed by AI (Artificial Intelligence). In this case, the AI ​​may be executed by the control device or another device (for example, an edge computer or a cloud server).

[0071] The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
