Description

Communication measurement method, program, and communication measurement system

[0001] The present disclosure generally relates to a communication measurement method, a program, and a communication measurement system, and more particularly to a communication measurement method, a program, and a communication measurement system relating to conversations between workers.

[0002] Patent Literature 1 discloses a communication evaluation system. The communication evaluation system of Patent Literature 1 calculates the distance between two people who belong to an organization based on location information data of mobile information terminals carried by the people who belong to the organization. The communication evaluation system of Patent Literature 1 determines that communication between the two people has been established if the calculated distance is within a predetermined distance for a predetermined consecutive period of time.

[0003] The communication evaluation system of Patent Document 1 determines whether communication (conversation) has been established based on two factors: the distance between the two people in question and the time. Therefore, it is possible that the two people in question are simply close to each other but are not actually communicating.

[0006] A communication measurement method according to one aspect of the present disclosure is executed by a computer system. The communication measurement method includes a selection step, a conversation determination step, and a calculation step. In the selection step, a first worker and a second worker are selected based on relationship information regarding a relationship between a worker and another worker. In the conversation determination step, it is determined whether the first worker and the second worker are conversing based on first location information, second location information, first audio information, and second audio information. The first location information is information indicating the location of the first worker. The second location information is information indicating the location of the second worker. The first audio information is information indicating the audio conditions around the first worker. The second audio information is information indicating the audio conditions around the second worker. In the calculation step, at least one of the number of conversations and the duration of the conversations between the first worker and the second worker is calculated based on the determination in the conversation determination step.

[0007] A program according to one aspect of the present disclosure is a program for causing one or more processors to execute the communication measurement method.

[0008] A communication measurement system according to one aspect of the present disclosure includes a selection unit, a conversation determination unit, and a calculation unit. The selection unit selects a first worker and a second worker based on relationship information regarding a relationship between a worker and another worker. The conversation determination unit determines whether the first worker and the second worker are conversing based on first location information, second location information, first audio information, and second audio information. The first location information is information indicating the location of the first worker. The second location information is information indicating the location of the second worker. The first audio information is information indicating the audio status around the first worker. The second audio information is information indicating the audio status around the second worker. The calculation unit calculates at least one of the number of conversations and the duration of the conversations between the first worker and the second worker based on the determination by the conversation determination unit.

[0010] Preferred embodiments of the present disclosure will be described in detail below with reference to the drawings. In the embodiments described below, common elements are designated by the same reference numerals, and redundant descriptions of the common elements may be omitted. The following embodiment is merely one of various embodiments of the present disclosure. Various modifications of the embodiment (including modifications) are possible depending on the design, etc., as long as the object of the present disclosure can be achieved. Furthermore, the embodiments (including modifications) may be realized in appropriate combinations.

[0011] (Embodiment) (1) Overview First, an overview of a communication measurement method, a program, and a communication measurement system 1 according to this embodiment will be described with reference to Fig. 1. The communication measurement system 1 of this embodiment is used to estimate worker engagement.

[0012] "Engagement" in this disclosure may include "work engagement" and "employee engagement." Engagement is defined, for example, in the following two respects: (1) commitment to an organization, specifically, affective commitment (emotional attachment to the organization) and continuance commitment (desire to stay with the organization); and (2) extra-role behavior (any behavior that enables the organization to function effectively).

[0013] In the present disclosure, the term "worker" may include anyone who works in general. In the present disclosure, the term "worker" may include not only those who receive compensation in exchange for their work, but also those who work without compensation. In this embodiment, as a representative example, a case will be described in which the engagement of a person who receives compensation in exchange for their work is estimated. Therefore, the communication measurement system 1 is used in, for example, a company, a government office, or an organization. Below, as a representative example, a case in which the communication measurement system 1 is used in a company will be described. In other words, the workplace of the worker in this embodiment is an office.

[0014] As shown in FIG. 1, the communication measurement system 1 of this embodiment includes a selection unit 211, a conversation determination unit 213, and a calculation unit 214.

[0015] The selection unit 211 selects a first worker and a second worker based on relationship information regarding the relationship between the worker and another worker.

[0016] The conversation determination unit 213 determines whether the first worker and the second worker are having a conversation based on the first location information, the second location information, and the first audio information and the second audio information. The first location information is information indicating the location of the first worker. The second location information is information indicating the location of the second worker. The first audio information is information indicating the audio state around the first worker. The second audio information is information indicating the audio state around the second worker.

[0017] In the present disclosure, the "state of sound around a worker" includes "a state in which no sound is being emitted around a worker" and "a state in which sound is being emitted around a worker." Furthermore, the "state in which sound is being emitted around a worker" may include a state in which, for example, another worker is emitting sound around a certain worker, and a state in which the worker himself is emitting sound. In other words, the state in which sound is being emitted around a first worker may include a state in which the first worker himself is emitting sound, and a state in which, for example, a second worker near the first worker is emitting sound.

[0018] The calculation unit 214 calculates at least one of the number of conversations and the duration of conversations between the first worker and the second worker based on the determination by the conversation determination unit 213 .

[0019] According to the communication measurement system 1 of this embodiment, whether or not workers are conversing with each other is determined based on the position information of the workers and sound information around the workers, and at least one of the number of conversations between the workers and the duration of the conversation is calculated. Therefore, the communication measurement system 1 of this embodiment can improve the measurement accuracy of conversations between workers compared to a system that determines whether or not workers are conversing with each other based on, for example, position information and duration.

[0020] Furthermore, functions similar to those of the communication measurement system 1 can be embodied in a communication measurement method. The communication measurement method of this embodiment is executed by a computer system (communication measurement system 1). The communication measurement method has a selection step, a conversation determination step, and a calculation step. In the selection step, a first worker and a second worker are selected based on relationship information regarding the relationship between the worker and another worker. In the conversation determination step, it is determined whether the first worker and the second worker are conversing based on first location information and second location information, and first voice information and second voice information. In the calculation step, at least one of the number of conversations and the conversation duration between the first worker and the second worker is calculated based on the determination in the conversation determination step.

[0021] The communication measurement method can also be embodied as a program. The program of this embodiment is a program for causing one or more processors of a computer system to execute the communication measurement method. The program may be recorded on a non-transitory recording medium readable by the computer system.

[0022] (2) Details The detailed configuration of the communication measurement system 1 according to this embodiment will be described below with reference to FIGS. 1 and 2. FIG.

[0023] (2.1) Communication Measurement System In this embodiment, there are multiple workers. The communication measurement system 1 estimates the engagement of each of the multiple workers for each predetermined estimation period. More specifically, the communication measurement system 1 calculates at least one of the number of conversations and the conversation duration between workers, and then estimates the engagement of each of the multiple workers. The predetermined estimation period is, for example, one week.

[0024] As shown in FIG. 1, the communication measurement system 1 includes a communication measurement device 2, a position measurement system 3, a voice collection system 4, a data server 5, an attendance management system 6, and a questionnaire system 7.

[0025] (2.2) Position Measurement System The position measurement system 3 measures the position information of each of the multiple workers. The position information includes, for example, coordinate information of each of the multiple workers. The "coordinates" are, for example, coordinates in an office (workplace).

[0026] 1, the position measurement system 3 includes a position measurement device 30, a plurality of mobile terminals 31, a plurality of imaging units 32, and a plurality of beacon devices 33. In the following description, each of the plurality of mobile terminals 31 may be simply referred to as a "mobile terminal 31." Each of the plurality of imaging units 32 may be simply referred to as an "imaging unit 32." Each of the plurality of beacon devices 33 may be simply referred to as a "beacon device 33."

[0027] The beacon devices 33 are installed on, for example, the ceiling, walls, floors, etc. of the workplace. The beacon devices 33 transmit (transmit) beacon signals. That is, the beacon devices 33 of this embodiment function as beacon transmitters.

[0028] The mobile terminal 31 is a terminal carried by each of a plurality of workers. The mobile terminal 31 is a smartphone, a laptop PC (personal computer), a wearable terminal, a dedicated beacon receiver, or the like. In this embodiment, the mobile terminal 31 is a smartphone. The mobile terminal 31 receives a beacon signal and measures the received signal strength of the beacon signal. The mobile terminal 31 transmits information about the received signal strength and identification information of the mobile terminal 31 to the position measurement device 30. The identification information of the mobile terminal 31 is associated with information about the worker who carries the mobile terminal 31.

[0029] The multiple imaging units 32 are installed, for example, on the ceiling or walls of the workplace. The imaging units 32 generate captured images with the periphery of the imaging units 32 as their imaging range. The imaging units 32 identify which of the multiple workers is included in the imaging range. For example, the imaging units 32 perform face detection processing on the captured image to detect human facial features, and extract facial images that are images of human facial features. When a facial image is extracted from the captured image, the imaging units 32 compare (match) the extracted facial image with facial images (template data) of multiple workers pre-registered, for example, in the data server 5, to identify the worker included in the imaging range.

[0030] After identifying the worker included in the imaging range, the imaging unit 32 transmits identification information about the identified worker and information indicating its own identifier to the position measurement device 30. Note that the information indicating the identifier may include location information indicating the location of the imaging unit 32.

[0031] The position measurement device 30 is, for example, a server. The position measurement device 30 is mainly composed of a computer system having one or more processors and one or more memories. In the position measurement device 30, the one or more processors execute a program recorded in the memory, thereby realizing the functions of the position measurement device 30. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0032] The position measurement device 30 calculates the distance between the mobile terminal 31 and each of the plurality of beacon devices 33 based on the information on the received signal strength received from the mobile terminal 31. Furthermore, the position measurement device 30 measures the position information of the mobile terminal 31 by three-point positioning based on the distance between the mobile terminal 31 and each of the plurality of beacon devices 33 and the position information of each of the plurality of beacon devices 33. The position measurement device 30 transmits the position information of the mobile terminal 31 to the communication measurement device 2 as the position information of the worker carrying the mobile terminal 31, that is, as the position information of the worker corresponding to the identification information of the mobile terminal 31.

[0033] In addition, based on the specific information received from the imaging unit 32 and information indicating the identifier of the imaging unit 32, the position measurement device 30 transmits, for example, the position information of the imaging unit 32 to the communication measurement device 2 as the position information of the worker included in the imaging range of the imaging unit 32.

[0034] The position measurement device 30 only needs to transmit to the communication measurement device 2 at least one of the position information of the mobile terminal 31 carried by the worker and the position information obtained by the imaging unit 32 capturing an image of the worker.

[0035] As described above, the first location information and the second location information in this embodiment are location information from the mobile terminals 31 carried by the first worker and the second worker, or location information obtained by capturing images of the first worker and the second worker using the imaging unit 32 installed in the workplace. By accurately measuring the locations of the workers using the location information from the mobile terminals 31 carried by the workers or location information obtained by capturing images of the workers using the imaging unit 32 installed in the workplace, it is possible to further improve the accuracy of measuring conversations between workers.

[0036] (2.3) Voice Collection System The voice collection system 4 collects voice information indicating the voice conditions around each of the multiple workers.

[0037] 1, the voice collection system 4 includes a voice collection device 40, a plurality of mobile terminals 41, and a plurality of microphones 42. In the following description, each of the plurality of mobile terminals 41 may be simply referred to as a "mobile terminal 41." Furthermore, each of the plurality of microphones 42 may be simply referred to as a "microphone 42."

[0038] The mobile terminal 41 is a smartphone, a laptop (personal computer), a wearable terminal, a voice recorder, or the like. In this embodiment, the mobile terminal 41 is a wearable terminal that the worker carries by wearing it on their arm. The mobile terminal 41 has a microphone and acquires audio information indicating the state of audio around the worker. The mobile terminal 41 transmits the acquired audio information to the audio collection device 40.

[0039] The mobile terminal 41 may have a function of measuring the worker's biological information. That is, the mobile terminal 41 may have a function as a biological information measuring terminal. The biological information includes, for example, at least one of heart rate, blood pressure, skin temperature, sweat rate, and voice information.

[0040] The microphones 42 are installed on the ceiling, walls, floor, etc. of the workplace. The microphones 42 acquire audio information indicating the state of sound around the microphones 42. The microphones 42 transmit the acquired audio information and information indicating the identifiers of the microphones 42 to the audio collection device 40.

[0041] The voice collecting device 40 is, for example, a server. The voice collecting device 40 mainly comprises a computer system having one or more processors and one or more memories. In the voice collecting device 40, the one or more processors execute a program recorded in the memory, thereby realizing the functions of the voice collecting device 40. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0042] The voice collecting device 40 transmits the voice information received from the mobile terminal 41 to the communication measuring device 2 as voice information indicating the state of voices around the worker carrying the mobile terminal 41 .

[0043] Furthermore, the voice collection device 40 of this embodiment performs voiceprint analysis on the voice information acquired by the microphone 42, thereby identifying which of the multiple workers has spoken the voice included in the voice information acquired by the microphone 42. The voice collection device 40 compares the voice included in the voice information acquired by the microphone 42 with voiceprint information of multiple workers registered in advance in, for example, the data server 5, and identifies the worker who spoke the voice included in the voice information acquired by the microphone 42.

[0044] After identifying the worker who made the sound included in the sound information acquired by the microphone 42, the sound collection device 40 transmits the sound information acquired by the microphone 42 to the communication measurement device 2 as sound information indicating the state of sound around the identified worker. More specifically, after identifying the worker, the sound collection device 40 transmits the sound information acquired by the microphone 42 to the communication measurement device 2 as sound information indicating the state of sound being made around the identified worker.

[0045] The voice collecting device 40 may transmit at least one of the voice information acquired by the mobile terminal 41 and the voice information acquired by the microphone 42 installed in the workplace to the communication measuring device 2 .

[0046] As described above, the first voice information and the second voice information in this embodiment are voice information acquired by the mobile terminal 41 carried by each of the first worker and the second worker, or voice information acquired by the microphone 42 installed in the workplace. By using the voice information acquired by the mobile terminal 41 carried by the workers or the voice information acquired by the microphone 42 installed in the workplace, it is possible to reduce the likelihood of determining that the workers are conversing when they are simply in close proximity to each other. Therefore, the communication measurement system 1 of this embodiment can further improve the measurement accuracy of conversations between workers.

[0047] (2.4) Data Server The data server 5 stores relationship information. The relationship information is information about the relationships between multiple workers in their workplace (a company, government office, organization, etc.). More specifically, the relationship information includes, for example, information about the hierarchical relationships between multiple workers. The information about the hierarchical relationships between multiple workers is, for example, information about the job positions of each of the multiple workers. A job position refers to a work position. A job position is a position or a rank, etc. In other words, the relationship information includes information about the position of a certain worker relative to another worker. For example, the relationship information associates information about Worker A with information about Worker B, who is Worker A's primary supervisor (immediate supervisor), information about Worker C, who is Worker A's secondary supervisor (the immediate supervisor of Worker A), information about Worker D, who is Worker A's colleague (with the same job position), and information about Worker E, who is Worker A's subordinate.

[0048] The relationship information also includes, for example, organizational information related to the organization (department or division, etc.) to which each of the multiple workers belongs. The department or division is distinguished by its name, for example, XXX Department, YYY Section, ZZZ Center, etc. The relationship information also includes, for example, task information related to the task (project, etc.) in which each of the multiple workers is involved.

[0049] The data server 5 also stores map information of workplaces. The map information includes information such as floor plan information of facilities used as workplaces. The map information may be, for example, three-dimensional model data such as building information modeling (BIM) data of the facilities.

[0050] The data server 5 of this embodiment transmits the relationship information and map information to the communication measurement device 2 .

[0051] (2.5) Attendance Management System The attendance management system 6 generates attendance information for each of a plurality of workers. The attendance information is information indicating the attendance status of a plurality of workers, including a first worker and a second worker. For example, each of the plurality of workers holds a mobile terminal 41 over a reading device of the attendance management system 6 when arriving at work and leaving work. The attendance management system 6 then reads the identification information of the mobile terminal 41 from the mobile terminal 41 and generates attendance information for each of the plurality of workers. The attendance information includes information on the arrival time and departure time. Note that an IC (Integrated Circuit) card or mobile terminal 31, etc. may also be configured to be held over a reading device of the attendance management system 6. The attendance management system 6 of this embodiment transmits the attendance information to the communication measurement device 2.

[0052] (2.6) Survey System The survey system 7 conducts surveys of multiple workers and stores the result information of the surveys.

[0053] The questionnaires conducted by the questionnaire system 7 may include, for example, a questionnaire regarding attendance, a daily report, a questionnaire for estimating engagement, etc. The result information of each questionnaire includes information regarding the work days of each of a plurality of workers including at least a first worker and a second worker.

[0054] The questionnaire system 7 of this embodiment transmits result information to the communication measurement device 2 .

[0055] (2.7) Communication Measurement Device As shown in FIG. 1, the communication measurement device 2 includes a control unit 21, a storage unit 22, and a communication unit 23.

[0056] The storage unit 22 is a storage device configured by a hard disk drive (HDD), a solid state drive (SSD), etc. The storage unit 22 stores information such as location information acquired from the position measurement system 3, voice information acquired from the voice collection system 4, relationship information acquired from the data server 5, attendance information acquired from the attendance management system 6, and result information acquired from the questionnaire system 7.

[0057] The communication unit 23 includes a communication interface device. The communication unit 23 is capable of communicating with external devices (e.g., the position measurement system 3, the voice collection system 4, the data server 5, the attendance management system 6, and the questionnaire system 7) via the communication interface device. In the present disclosure, "capable of communication" means being able to send and receive signals directly or indirectly via a network, a repeater, or the like, using an appropriate communication method such as wired communication or wireless communication.

[0058] The control unit 21 includes a computer system having one or more processors and a memory. The functions of the control unit 21 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0059] The control unit 21 includes a selection unit 211 , an attendance determination unit 212 , a conversation determination unit 213 , a calculation unit 214 , and an estimation unit 215 .

[0060] The selection unit 211 performs a selection process (selection step) to select a first worker and a second worker based on relationship information regarding the relationship between the worker and another worker.

[0061] The selection unit 211 of this embodiment selects a worker whose engagement is to be estimated as a first worker. Furthermore, the selection unit 211 selects the first worker's superior, the first worker's subordinate, a colleague in the same department as the first worker, etc. as a second worker based on the relationship information. In other words, the selection unit 211 selects a worker who has a predetermined relationship with the first worker as a second worker based on the relationship information.

[0062] The communication measurement system 1 of this embodiment estimates the engagement of each of a plurality of workers. That is, the selection unit 211 of this embodiment selects each of the plurality of workers as a first worker. Furthermore, the selection unit 211 selects one or more second workers for each first worker.

[0063] The selection unit 211 selects the first worker and the second worker based on the relationship information, and all pair combinations of multiple workers (for example, when the number of multiple workers is n, ｎ C ２ The number of communication measurements can be reduced compared to measuring communication between two workers (pairs). In other words, by having the selection unit 211 select the first worker and the second worker based on the relationship information, the time required for communication measurement can be shortened and the load on the communication measurement system 1 can be reduced. Furthermore, because the relationship information includes information regarding the level of job position between the workers, the selection unit 211 can select the second worker who has a specific job position (has a predetermined relationship) from the perspective of the first worker. Therefore, according to the communication measurement system 1 of this embodiment, the amount of conversation (amount of communication) between the first worker and the second worker who has a specific job position from the perspective of the first worker can be efficiently measured.

[0064] The attendance determination unit 212 performs an attendance determination process (attendance determination step) to determine the attendance status of the first worker and second worker selected by the selection unit 211. More specifically, in the attendance determination process, the attendance determination unit 212 determines whether both the first worker and the second worker are at work for each workday included in a predetermined estimated period. Note that the attendance determination unit 212 may also determine the attendance status of the first worker and the second worker for each predetermined period that divides workdays into more detailed periods such as "morning" and "afternoon."

[0065] In the attendance determination process, the attendance determination unit 212 of this embodiment determines the attendance status of the first worker and the second worker based on at least one of the first and second location information, attendance information, and questionnaire result information. For example, the attendance determination unit 212 determines that the worker is present at work on a workday (or a predetermined period) for which the worker's location information is acquired. On the other hand, the attendance determination unit 212 determines that the worker is not present at work (absent) on a workday for which the worker's location information is not acquired. By determining the attendance status of the first and second workers based on at least one of the first and second location information, attendance information, and questionnaire result information, the accuracy of determining the attendance status can be improved.

[0066] The conversation determination unit 213 obtains location information from the location measurement system 3, voice information from the voice collection system 4, relationship information and map information from the data server 5, attendance information from the attendance management system 6, and result information from the questionnaire system 7.

[0067] The conversation determination unit 213 performs a conversation determination process (conversation determination step) to determine whether or not workers are conversing with each other based on a plurality of pieces of location information and a plurality of pieces of voice information. More specifically, the conversation determination unit 213 performs a conversation determination process (conversation determination step) to determine whether or not a first worker and a second worker are conversing with each other based on the first location information and the second location information, and the first voice information and the second voice information.

[0068] In the conversation determination process, the conversation determination unit 213 of this embodiment determines that the first worker and the second worker are conversing on the condition that the first voice information indicates that voice is being emitted around the first worker and the second voice information indicates that voice is being emitted around the second worker. On the other hand, the conversation determination unit 213 determines that the first worker and the second worker are not conversing when at least one of the first voice information and the second voice information indicates that voice is not being emitted. Since the conversation determination unit 213 determines that the first worker and the second worker are conversing when both the first voice information and the second voice information indicate that voice is being emitted, it is possible to further improve the accuracy of measuring the conversation between workers.

[0069] Furthermore, in the conversation determination process, the conversation determination unit 213 of this embodiment performs a proximity determination process (proximity determination step) in which it determines whether the first worker and the second worker are in close proximity based on the first location information and the second location information. Then, the conversation determination unit 213 determines that the first worker and the second worker are conversing, provided that it determines that the first worker and the second worker are in close proximity in the conversation determination process. On the other hand, if it determines that the first worker and the second worker are not in close proximity, it determines that the first worker and the second worker are not conversing. Because it determines that the first worker and the second worker are conversing, provided that the first worker and the second worker are in close proximity, it is possible to further improve the accuracy of measuring the conversation between workers.

[0070] Furthermore, in the proximity determination process (conversation determination process), the conversation determination unit 213 of this embodiment determines that the first worker and the second worker are in proximity if the distance between them is less than a predetermined distance or if the first worker and the second worker are in the same room (space). In other words, the conversation determination unit 213 determines that the first worker and the second worker are in proximity if the distance between the position of the first worker indicated by the first location information and the position of the second worker indicated by the second location information is less than a predetermined distance or if the position of the first worker indicated by the first location information and the position of the second worker indicated by the second location information are in the same room. On the other hand, the conversation determination unit 213 determines that the first worker and the second worker are not in proximity if the distance between them is equal to or greater than a predetermined distance and / or if the first worker and the second worker are in different rooms (spaces). The predetermined distance is, for example, one meter. The conversation determination unit 213 determines whether the first worker and the second worker are in the same room based on the first location information, the second location information, and the map information. Whether the workers are in close proximity to each other is determined based on whether the distance between the first worker and the second worker is less than a predetermined distance or whether the first worker and the second worker are in the same room, thereby improving the accuracy of determining whether the workers are in close proximity to each other.

[0071] Furthermore, when the attendance determination unit 212 determines in the attendance determination process that the first worker and the second worker are both at work, the conversation determination unit 213 of this embodiment performs a conversation determination process (conversation determination step) for the workdays (or predetermined period) on which it is determined that the first worker and the second worker are both at work. If there are multiple workdays on which the first worker and the second worker are both at work within the predetermined estimated period, the conversation determination unit 213 performs the conversation determination process for multiple workdays.

[0072] On the other hand, if the attendance determination process determines that at least one of the first worker and the second worker is not at work (is absent), the conversation determination unit 213 does not perform the conversation determination process. By performing the conversation determination process only when it is determined that both the first worker and the second worker are at work, the period covered by the conversation determination process is limited, thereby reducing the load on the conversation determination unit 213.

[0073] 2 is a conceptual diagram showing the concept of the conversation determination process by the conversation determination unit 213. The conversation determination process will be described below with reference to FIG.

[0074] The "first audio flag" in FIG. 2 is an audio flag related to the first audio information, and the "second audio flag" is an audio flag related to the second audio information. When the audio information indicates that audio is being generated around the worker, the audio flag is turned on. On the other hand, when the audio information indicates that audio is not being generated around the worker, the audio flag is turned off. For example, the audio flag is updated every minute.

[0075] The "proximity flag" in Figure 2 is a flag related to the result of the proximity determination process. If the proximity determination process determines that the first worker and the second worker are in close proximity, the proximity flag is set to ON. On the other hand, if the proximity determination process determines that the first worker and the second worker are not in close proximity, the proximity flag is set to OFF. For example, the proximity flag is updated every minute.

[0076] The "conversation flag" in Figure 2 is a flag related to the result of the conversation determination process. If the conversation determination process determines that the first worker and the second worker are having a conversation, the conversation flag is turned on. On the other hand, if the conversation determination process determines that the first worker and the second worker are not having a conversation, the conversation flag is turned off. For example, the conversation flag is updated every minute.

[0077] In this embodiment, the conversation determination unit 213 determines that the first worker and the second worker are conversing when the first voice information indicates that voice is being generated around the first worker, the second voice information indicates that voice is being generated around the second worker, and the first worker and the second worker are determined to be in close proximity. In other words, the conversation determination unit 213 determines that the first worker and the second worker are conversing when all of the first voice flag, the second voice flag, and the proximity flag are on. On the other hand, the conversation determination unit 213 determines that the first worker and the second worker are not conversing when at least one of the first voice flag, the second voice flag, and the proximity flag is off.

[0078] 2, the conversation flag is on in the period between timing T1 and timing T2, the period between timing T3 and timing T4, the period between timing T5 and timing T6, and the period between timing T7 and timing T8. Note that the period between timing T0 and timing T9 is, for example, one workday or a predetermined period.

[0079] The calculation unit 214 performs a calculation process (calculation step) for each predetermined estimation period to calculate at least one of the number of conversations and the conversation duration between the first worker and the second worker within the predetermined estimation period. The calculation unit 214 performs the calculation process based on the determination in the conversation determination process. If there are multiple workdays within the predetermined estimation period on which the first worker and the second worker both come to work, the calculation unit 214 calculates at least one of the number of conversations and the conversation duration between the first worker and the second worker on the multiple workdays.

[0080] In the calculation process, the calculation unit 214 of this embodiment determines the start time and end time of the conversation between the first worker and the second worker, and then calculates at least one of the number of conversations and the conversation duration between the first worker and the second worker.

[0081] 2, the calculation unit 214 determines that timing T1, timing T3, timing T5, and timing T7 are the start times of the conversation. The calculation unit 214 also determines that timing T2, timing T4, timing T6, and timing T8 are the end times of the conversation. In other words, the calculation unit 214 of this embodiment determines that the timing when the conversation flag is turned on is the start time of the conversation, and determines that the timing when the conversation flag is turned off is the end time of the conversation.

[0082] Therefore, in this embodiment, the calculation unit 214 determines the number of times the conversation flag is turned on or off as the conversation count, and the total time that the conversation flag is on as the conversation time. In the example of Figure 2, the calculation unit 214 calculates (measures) that the number of conversations between the first worker and the second worker on a certain workday is four. The calculation unit 214 also calculates the total conversation time between the first worker and the second worker on a certain workday as the sum of the time between timing T1 and timing T2, the time between timing T3 and timing T4, the time between timing T5 and timing T6, and the time between timing T7 and timing T8.

[0083] In the calculation process of this embodiment, the start time and end time of the conversation are determined, and then at least one of the number of conversations and the conversation duration between the first worker and the second worker is calculated, thereby improving the accuracy of calculating the number of conversations or the conversation duration.

[0084] The estimation unit 215 performs an estimation process (estimation step) to estimate the engagement of each of the multiple workers for each predetermined estimation period. The estimation unit 215 of this embodiment estimates the engagement of the first worker based on at least one of the number of conversations and the conversation duration calculated in the calculation process. That is, the estimation unit 215 of this embodiment uses at least one of the number of conversations and the conversation duration between the first worker and the second worker calculated in the calculation process as a parameter for estimating the engagement of the first worker. Because the engagement of the workers is estimated based on at least one of the number of conversations and the conversation duration calculated in the calculation process, the accuracy of the engagement estimation can be improved.

[0085] Furthermore, in the estimation process of this embodiment, when the second worker is the first worker's boss, the impact of the number of conversations on engagement per conversation and the impact of the conversation time per unit time on engagement are greater than when the second worker is not the first worker's boss, for example, a colleague. In other words, when the second worker is the first worker's boss, if the number of conversations between the first worker and the second worker is high or the conversation time is long, the first worker's engagement is likely to be high. In the estimation process of this embodiment, the impact on engagement is adjusted depending on the worker's job position, thereby improving the accuracy of engagement estimation.

[0086] (3) Operation of the Communication Measurement System Next, the operation of the communication measurement system 1 will be described with reference to FIG.

[0087] First, the communication measurement system 1 performs a selection process (selection step) (S1). That is, the communication measurement system 1 selects one first worker and one or more second workers from among multiple workers based on the relationship information. Here, the communication measurement system 1 may select multiple second workers for one first worker. If multiple second workers are selected in the selection process, the communication measurement system 1 of this embodiment performs the following processes of steps S2 to S5 for each of the selected multiple second workers. That is, the communication measurement system 1 of this embodiment repeats the processes of steps S2 to S5 the same number of times as the number of selected second workers.

[0088] Next, the communication measurement system 1 performs an attendance determination process (attendance determination step) (S2). That is, the communication measurement system 1 determines the attendance status of the first worker and the second worker, and selects workdays (predetermined period) on which both the first worker and the second worker are present at work from within a predetermined estimated period.

[0089] Next, the communication measurement system 1 performs a conversation determination process (conversation determination step) (S3). That is, the communication measurement system 1 determines whether the first worker and the second worker are having a conversation based on the first location information, the second location information, the first voice information, and the second voice information.

[0090] Next, the communication measurement system 1 performs a calculation process (calculation step) (S4). That is, the communication measurement system 1 calculates at least one of the number of conversations and the conversation duration between the first worker and the second worker during a predetermined estimation period based on the judgment in the conversation judgment process.

[0091] Next, the communication measurement system 1 determines whether or not at least one of the number of conversations and the conversation duration has been calculated for all combinations of the one first worker selected in the selection process and one or more second workers. In other words, the communication measurement system 1 determines whether or not there are any other second workers for whom the number of conversations and the conversation duration with the first worker need to be calculated (S5).

[0092] If there is another second worker for whom the number of conversations and the conversation duration need to be calculated (S5: Yes), the process returns to step S2. On the other hand, if there is no other second worker for whom the number of conversations and the conversation duration need to be calculated (S5: No), that is, if at least one of the number of conversations and the conversation duration between each of the one or more second workers selected in the selection process and the first worker has already been calculated, the process proceeds to step S6.

[0093] In step S6, the communication measurement system 1 performs an estimation process (estimation step) (S6). That is, the communication measurement system 1 estimates the engagement of the first worker based on at least one of the number of conversations and the conversation duration calculated in the calculation process. Then, the communication measurement system 1 ends the process.

[0094] The flowchart shown in FIG. 3 is merely an example, and the order of the processes may be changed as appropriate, and processes may be added or deleted as appropriate.

[0095] (4) Modifications Modifications of the above embodiment are listed below.

[0096] (4.1) First Modification In the calculation process, if the time between the end time of the first conversation and the start time of the second conversation is shorter than a predetermined time, the calculation unit 214 may consider the first conversation and the second conversation to be one conversation and calculate at least one of the number of conversations and the conversation duration between the first worker and the second worker. The first conversation is a conversation between the first worker and the second worker. The second conversation is a conversation between the first worker and the second worker that took place after the first conversation. The predetermined time is, for example, 10 minutes. The predetermined time may be set as appropriate.

[0097] For example, the calculation unit 214 determines whether the time between the time when the conversation flag changes from on to off and the time when the conversation flag next changes from off to on is shorter than a predetermined time.

[0098] 2, the calculation unit 214 determines whether the time between timing T2 and timing T3 is shorter than a predetermined time. If the time between timing T2 and timing T3 is shorter than the predetermined time, the calculation unit 214 determines that the first conversation that took place from timing T1 to timing T2 and the second conversation that took place from timing T3 to timing T4 are one continuous conversation. In other words, if the time between timing T2 and timing T3 is shorter than the predetermined time, the calculation unit 214 determines that one continuous conversation took place from timing T1 to timing T4.

[0099] Similarly, the calculation unit 214 determines whether the time between timing T4 and timing T5 is shorter than a predetermined time, and determines whether the time between timing T6 and timing T7 is shorter than a predetermined time.

[0100] In the following, we will assume that the calculation unit 214 determines that the time between timing T2 and timing T3 is shorter than a predetermined time, the time between timing T4 and timing T5 is longer than a predetermined time, and the time between timing T6 and timing T7 is shorter than a predetermined time. In this case, the calculation unit 214 determines that one continuous conversation took place from timing T1 to timing T4, and determines that one continuous conversation took place from timing T5 to timing T8. The calculation unit 214 then calculates (measures) that the number of conversations between the first worker and the second worker on a certain workday is two. The calculation unit 214 also calculates the sum of the time between timing T1 and timing T4 and the time between timing T5 and timing T8 as the conversation time between the first worker and the second worker on a certain workday.

[0101] According to the communication measurement system 1 of the first variant, it is possible to suppress a decrease in the calculation accuracy of the number of conversations and conversation duration due to a loss of location information and voice information, or an accuracy limit of the location information and voice information.

[0102] (4.2) Other Variations The execution entity of the communication measurement system 1 or communication measurement method of the present disclosure includes a computer system. The computer system is primarily composed of a processor and memory as hardware. The processor executes a program recorded in the memory of the computer system to realize the functions of the execution entity of the communication measurement system 1 or communication measurement method of the present disclosure. The program may be pre-recorded in the memory of the computer system, provided via a telecommunications line, or provided by being recorded on a non-transitory recording medium readable by the computer system, such as a memory card, optical disk, or hard disk drive. The processor of the computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits, such as ICs and LSIs, are referred to by different names depending on the degree of integration, and include integrated circuits called system LSIs, very large-scale integration (VLSI), or ultra-large-scale integration (ULSI). Furthermore, a field-programmable gate array (FPGA), which is programmed after the LSI is manufactured, or a logic device capable of reconfiguring the connections within the LSI or the circuit partitions within the LSI, can also be employed as a processor. Multiple electronic circuits may be integrated into a single chip or distributed across multiple chips. Multiple chips may be integrated into a single device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits, including a semiconductor integrated circuit or a large-scale integrated circuit.

[0103] Furthermore, it is not essential for the communication measurement system 1 that multiple functions are concentrated in one housing, and the components of the communication measurement system 1 may be distributed across multiple housings. Furthermore, at least some of the functions of the communication measurement system 1, for example, some of the functions of the communication measurement device 2, may be realized by the cloud (cloud computing) or the like.

[0104] Conversely, in the above embodiment, at least some of the functions of the communication measurement system 1 that are distributed across multiple devices may be consolidated into a single housing. For example, some of the functions of the communication measurement system 1 that are distributed across the data server 5 and the attendance management system 6 may be consolidated into a single housing.

[0105] The communication measurement system 1 only needs to include at least a selection unit 211, a conversation determination unit 213, and a calculation unit 214. In other words, the communication measurement system 1 only needs to be able to calculate at least one of the number of conversations and the conversation duration between workers, and it is not essential that the communication measurement system 1 be used to estimate worker engagement.

[0106] One of the mobile terminal 31 and the mobile terminal 41 may also serve as the other of the mobile terminal 31 and the mobile terminal 41. In other words, the mobile terminal 31 may acquire voice information indicating the state of voices around the worker and transmit the acquired voice information to the voice collecting device 40. The mobile terminal 41 may also receive a beacon signal, measure the received signal strength of the beacon signal, and transmit information on the received signal strength to the position measuring device 30.

[0107] In the above embodiment, the case where the imaging unit 32 identifies the workers included in the imaging range has been exemplified, but it is not essential that the imaging unit 32 identify the workers included in the imaging range. For example, the position measurement device 30 may receive the captured image and information indicating the identifier of the imaging unit 32 from the imaging unit 32 and identify the workers included in the imaging range of the captured image.

[0108] (Summary) As described above, the communication measurement method according to the first aspect is executed by a computer system. The communication measurement method includes a selection step, a conversation determination step, and a calculation step. In the selection step, a first worker and a second worker are selected based on relationship information regarding the relationship between the worker and another worker. In the conversation determination step, it is determined whether the first worker and the second worker are having a conversation based on first location information, second location information, first audio information, and second audio information. The first location information is information indicating the location of the first worker. The second location information is information indicating the location of the second worker. The first audio information is information indicating the audio status around the first worker. The second audio information is information indicating the audio status around the second worker. In the calculation step, at least one of the number of conversations and the duration of the conversations between the first worker and the second worker is calculated based on the determination in the conversation determination step.

[0114] The communication measurement method according to the fourth aspect is any one of the first to third aspects, in which in the conversation determination step, it is determined that the first worker and the second worker are having a conversation, provided that the first voice information indicates that voice is being made around the first worker and the second voice information indicates that voice is being made around the second worker.

[0115] According to this aspect, if both the first voice information and the second voice information indicate that voice is being emitted, it is determined that the first worker and the second worker are having a conversation, thereby further improving the accuracy of measuring conversations between workers.

[0116] The communication measurement method of the fifth aspect is any of the first to fourth aspects, in which the conversation determination step determines whether the first worker and the second worker are in close proximity based on the first location information and the second location information, and if it is determined that the first worker and the second worker are in close proximity, it determines that the first worker and the second worker are having a conversation.

[0117] According to this aspect, the first worker and the second worker are determined to be conversing only if they are in close proximity to each other, thereby further improving the accuracy of measuring conversations between workers.

[0118] A sixth aspect of the communication measurement method is any one of the first to third aspects, and in the conversation determination step, it is determined whether the first worker and the second worker are in close proximity based on the first location information and the second location information. In the conversation determination step, it is determined that the first worker and the second worker are conversing on the condition that the first voice information indicates that voice is being generated around the first worker, the second voice information indicates that voice is being generated around the second worker, and it is determined that the first worker and the second worker are in close proximity.

[0119] According to this aspect, it is determined that the first worker and the second worker are conversing when the first worker and the second worker are in close proximity and both the first voice information and the second voice information indicate that voice is being emitted, thereby further improving the accuracy of measuring conversations between workers.

[0120] The communication measurement method of the seventh aspect is the fifth or sixth aspect, in which the conversation determination step determines that the first worker and the second worker are in close proximity if the distance between them is less than a predetermined distance or if the first worker and the second worker are in the same room.

[0121] According to this aspect, it is possible to improve the accuracy of determining whether workers are in close proximity to each other.

[0122] The communication measurement method according to an eighth aspect is the method according to any one of the first to seventh aspects, further comprising an attendance determination step. In the attendance determination step, the attendance status of the first worker and the second worker is determined. If it is determined in the attendance determination step that both the first worker and the second worker are at work, a conversation determination step is performed.

[0123] According to this aspect, the conversation determination step is performed when it is determined that both the first worker and the second worker are at work, so the load in the conversation determination step can be reduced.

[0124] A communication measurement method according to a ninth aspect is the eighth aspect, in which the attendance determination step determines the attendance status of the first worker and the second worker based on at least one of the first location information and the second location information, attendance information indicating the attendance status of the first worker and the second worker, and result information of a survey of the workers.

[0125] According to this aspect, it is possible to improve the accuracy of determining the attendance status.

[0126] The communication measurement method according to the tenth aspect is any one of the first to ninth aspects, in which the calculation step determines the start and end times of a conversation between a first worker and a second worker and then calculates at least one of the number of conversations and the conversation duration.

[0127] According to this aspect, the start time and end time of the conversation are determined, and then at least one of the number of conversations and the conversation duration between the first worker and the second worker is calculated, thereby improving the accuracy of calculating the number of conversations or the conversation duration.

[0128] A communication measurement method according to an eleventh aspect is the tenth aspect, wherein in the calculation step, if the time between the end time of the first conversation and the start time of the second conversation is shorter than a predetermined time, the first conversation and the second conversation are considered to be one conversation, and at least one of the number of conversations and the conversation duration is calculated. The first conversation is a conversation between a first worker and a second worker. The second conversation is a conversation between the first worker and a second worker, and is a conversation that takes place after the first conversation.

[0129] According to this aspect, it is possible to suppress a decrease in the accuracy of calculating the number of conversations and the conversation duration due to a loss of position information and voice information, or a limit in the accuracy of the position information and voice information.

[0130] In a communication measurement method according to a twelfth aspect, in any one of the first to eleventh aspects, the relationship information includes information regarding the rank of the worker relative to another worker.

[0131] According to this aspect, the relationship information includes information regarding the positional status of the workers, so for example, a worker who is the first worker's boss and has a high influence on the first worker's engagement can be selected as the second worker.

[0132] A thirteenth aspect of the communication measurement method is the method of any one of the first to twelfth aspects, further comprising an estimation step of estimating the engagement of the first worker based on at least one of the number of conversations and the conversation duration calculated in the calculation step.

[0133] According to this aspect, the worker's engagement is estimated based on at least one of the number of conversations and the conversation duration calculated in the calculation step, thereby improving the accuracy of engagement estimation.

[0134] A communication measurement method according to a fourteenth aspect is the thirteenth aspect, wherein in the estimation step, when the second worker is the boss of the first worker, the impact of the number of conversations on engagement per conversation and the impact of the conversation time on engagement per unit time are greater than when the second worker is not the boss of the first worker.

[0135] According to this aspect, the degree of influence on engagement is adjusted depending on the worker's job position, thereby improving the accuracy of engagement estimation.

[0136] The configurations other than the first aspect are not essential for the communication measurement method and can be omitted as appropriate.

[0137] A program according to a fifteenth aspect is a program for causing one or more processors to execute the communication measurement method according to any one of the first to fourteenth aspects.

[0138] According to this aspect, the accuracy of measuring conversations between workers can be improved compared to a system that determines whether workers are talking to each other based on, for example, location information and time.

[0139] A communication measurement system (1) according to a sixteenth aspect includes a selection unit (211), a conversation determination unit (213), and a calculation unit (214). The selection unit (211) selects a first worker and a second worker based on relationship information relating to a relationship between a worker and another worker. The conversation determination unit (213) determines whether the first worker and the second worker are conversing based on first location information, second location information, first audio information, and second audio information. The first location information is information indicating the location of the first worker. The second location information is information indicating the location of the second worker. The first audio information is information indicating the audio state around the first worker. The second audio information is information indicating the audio state around the second worker. The calculation unit (214) calculates at least one of the number of conversations and the duration of the conversations between the first worker and the second worker based on the determination by the conversation determination unit (213).
