Description

  The present invention relates to a measurement system that collects, analyzes, and displays physical interactions between users by allowing a user to carry a device for measuring and recording the behavior and collecting the behavior data.

  Research has been conducted on services for acquiring and analyzing behavioral data of workers in an organization and using them to improve management and look back on the workers themselves (Non-patent Document 1). This is because, among behavioral data, physical interaction between workers seems to have an important influence on the creativity or productivity of an organization. Here, the physical interaction broadly means a physical interaction between workers, such as a conversation between workers or the frequency of attending a meeting.

  The physical interaction can be measured by attaching a behavior data collection device for recording behavior such as an RF (Radio Frequency) ID tag for detecting a place and various sensors to the worker himself / herself. A person who wants to analyze physical interaction using the measured behavior data distributes the behavior data collection device to the worker and asks him to carry it. Furthermore, a data collection server for collecting behavior data of the behavior data collection device is prepared, and a data collection system for collecting behavior data in the server is constructed. Patent Documents 1 and 2 disclose techniques related to an action data collection device that can be used for this purpose.

This behavioral data collection device needs to be designed with due consideration to the concerns about privacy infringement that workers have. For example, even if the behavior data collection device is equipped with a microphone for acquiring the voice of the worker, did the voice of the mobile phone not be recorded with such an accuracy that the content could be discriminated, and whether there was utterance at a certain time? It is conceivable to reduce the recording accuracy, such as recording only whether or not.

  However, there is a problem that when the behavior data collection device is used to acquire the worker's behavior data, the worker's anxiety about the data collection system needs to be resolved. Workers who have never used a behavior data collection device often cannot fully understand what data is collected and how it is used, even if they receive verbal or written explanations. Therefore, even if the data collection system (behavior data collection device) was designed with sufficient consideration for the privacy of the workers, the workers refused to carry the behavior data collection device because of anxiety and cooperated in data collection There are things that do not.

Terminal devices 7, 8, and 9, behavior data collection server 10, and behavior data mediation server 11 used by three workers 1, 2, and 3, respectively, are connected to a LAN (Local Area Network). Workers 1, 2, and 3 wear behavior data collection devices 4, 5, and 6, respectively. The terminal devices 7, 8, and 9 are assumed to be PCs (Personal Computers) here, but may satisfy the screen display function, the communication function that can communicate with the LAN, and the functions of the terminal devices 7, 8, and 9 described later. For example, a PDA (Personal Digital Assistant) or a mobile phone may be used. Here, the behavior data means data recorded by the behavior data collection devices 4, 5, 6.

  Each of the behavior data collection devices 4, 5, and 6 has a unique 32-bit ID. The IDs of the behavior data collection devices 4, 5, and 6 are 1, 2, and 3, respectively. The bit length of the ID may be another length, and the format of this ID may be in a form compliant with a standard one such as an IP address, a MAC address, or a URL.

  A person who wants to measure / analyze the behavior data of an organization and physical interaction distributes the behavior data collection devices 4, 5, 6 to the user (subject) and instructs them to carry or wear it. Display software to be described later is installed in the terminal devices 7, 8, and 9 used by the user. This display software always operates in the background while the OS (Operating System) of the terminal devices (PCs) 7, 8, and 9 is activated.

  The action data collection devices 4, 5 and 6, the terminal devices 7, 8 and 9, the action data collection server 10, and the action data mediation server 11 are configured by each device or the CPU provided in the server. May be realized by executing a program corresponding to each means stored in a ROM (Random Access Memory) or HDD (Hard Disc Drive) included in the computer, and the processing related to each means may be realized by hardware. It is good also as a form.

<Behavior data collection device>
The behavior data collection devices 4, 5, and 6 according to the present embodiment will be described with reference to FIG. The behavior data collection devices 4, 5, and 6 are attached to the chest by clips or the like even when the behavior data collection devices 4, 5, and 6 are suspended from the neck of a worker like a company ID card generally used in an office. It may be in a form that is used. The behavior data collection devices 4, 5, 6 include a voice detection unit 12, a proximity notification unit 13, a face-to-face notification unit 14, an ID holding unit 15, a data transmission unit 16, an RTC (Real-Time Clock) 17, a data holding unit 18, The battery unit 19 is configured.

The voice detection unit 12 has a function of acquiring the voice of the user, and is composed of an analog circuit such as a microphone or an operational amplifier for amplifying the output of the microphone and a frequency filter for appropriately detecting the voice.
The proximity notification unit 13 includes a wireless communication module, and has a function of detecting the proximity of each other by transmitting and receiving mutual IDs to and from a behavior data collection device that exists within the reach of wireless communication. It is also possible to determine whether or not the transmitter is nearby by determining whether or not the signal strength of the transmitter is greater than a threshold value.

The face-to-face notification unit 14 includes an infrared transmission / reception module, and has a function of detecting the face-to-face of a worker by transmitting and receiving an ID with another action data collection device facing each other by infrared light.
Each ID holding unit 15 has a function of holding a unique ID.
The data transmission unit 16 has a function of transmitting data held by the data holding unit 18 to the terminal device, and a communication interface provided in the data transmission unit 16 is a standardized wireless such as BLUETOOTH (registered trademark), ZIGBEE, WIFI, or the like. Although it is a communication interface, it may be a non-standardized wireless communication interface or a wired communication standard such as USB (Universal Serial Bus).

An RTC (Real-Time Clock) 17 is an RTC module that holds the current time.
The data holding unit 18 detects the voice data detected by the voice detection unit 12, the ID of another behavior data collection device detected by the proximity detection unit 13, and the ID of another behavior data collection device detected by the face-to-face detection unit 14. It has a function to record with time.
The battery unit 19 is a battery for supplying power to each unit of the behavior data collection devices 4, 5, 6, and may include a charging mechanism for charging the secondary battery.

  Here, the audio | voice detection part 12, the facing detection part 13, and the proximity detection part 14 are good also as a form which has any one. When there is no voice detection unit 12, the user (subject) does not need to wear the behavior data collection devices 4, 5, and 6 near the mouth. Further, when the face-to-face detection unit 14 is not provided, the user does not need to wear the behavior data collection devices 4, 5, 6 on the front front of the body. Furthermore, when neither the voice detection unit 12 nor the face-to-face detection unit 14 is present, the user can wear the behavior data collection devices 4, 5, and 6 anywhere and can wear them anywhere, such as a mobile phone or PDA. The portable data device may also serve as the behavior data collection devices 4, 5, and 6, and the behavior data collection devices 4, 5, and 6 may be retrofitted to such portable devices.

<Data transmission / reception between action data collection device and terminal device>
FIG. 3 is a diagram in which the behavior data collection devices 4, 5, 6 transmit behavior data to the terminal devices 7, 8, 9 by the data transfer unit 16 by wireless communication. Here, the display software operating on the terminal devices 7, 8, and 9 acquires the behavior data only from the behavior data collection device used by the user of the terminal, so that the ID of the behavior data collection device is obtained. I remember one. For example, when the display software is installed, the user inputs the ID by inputting the ID of the behavior data collection device worn by the user. In the present embodiment, it is assumed that the display software holds the ID of the behavior data collection device that has been input by the user.

  The ID may be input by holding a user ID for the display software to identify the employee and referring to a correspondence table of the user ID and the action data collection device ID. May be a user management table 47 to be described later. The user ID is a character string that allows a worker to determine who the worker is by looking at the ID, and is generally used for the purpose of identifying an employee.

  FIG. 4 shows the structure of transmission data that the behavior data collection device transmits to the terminal device. The action data to be transmitted is action data composed of three tables, the utterance data table 20, the proximity data table 21, and the face-to-face data table 22, and the time when the action data is measured by the action data collection device. Time data (behavior data / time stamp 23).

The procedure for transmitting the behavior data and behavior data / time stamp will be described with reference to FIG. In S1, the data transmission unit 16 of the behavior data collection device transmits a behavior data presence notification packet periodically to notify that there is behavior data to be transmitted, for example, every hour. The terminal device that has received the behavior data presence notification packet in S2 transmits a behavior data request packet for requesting behavior data in S3 to the behavior data collection device.
The behavior data collection device that has received the behavior data request packet in S4 and S5 transmits the behavior data and the behavior data / time stamp to the terminal device. If the transmission is successful, the behavior data collection device deletes the transmitted behavior data from the data holding unit 18.

  The terminal device that has received the behavior data and the behavior data / time stamp in S6, S7, and S8 replaces the behavior data collection device ID in the behavior data with the user ID, and updates the self behavior data DB (described later). Here, the replacement of the IDs 28 and 31 of the behavior data collection device with the user ID is performed by referring to a correspondence table described later.

<Data structure of action data DB according to the present embodiment>
FIG. 6 is a diagram illustrating a configuration of a self-action data DB used by the terminal device to accumulate action data received from the action data collection device, and the DB includes self-action data and self-action data / time stamp. . The self-action data is composed of three tables, a utterance data table 33, a proximity data table 34, and a face-to-face data table 35. Each time action data is received, a corresponding data table of the received data is accumulated in the three tables. Is done. The self-action data time stamp 36 is updated to the action data time stamp of the received data every time data is received.

<Data structure of DB for action data mediation according to this embodiment>
Hereinafter, a method in which a plurality of terminal devices transmit / receive behavior data to each other will be described. First, the configuration of the behavior data mediation DB will be described with reference to FIG. The terminal device uses the behavior data mediating server 11 to discover other terminal devices that transmit / receive behavior data to / from each other. The behavior data mediation server 11 holds a behavior data mediation DB. The behavior data mediation DB has a behavior data mediation table 46 and a user management table 47. The behavior data mediating server 11 collects self behavior data and time stamps held by each terminal device and stores them in the behavior data mediating table 46. The user management table 47 stores information about the user input in advance when constructing the data collection system and the ID of the action data collection device distributed to each user.

  The action data mediation table 46 includes a user ID 48, a user terminal 49, which is information for another terminal device to access the user terminal device (or a display device that operates on the terminal device), and the user's self. It is a table composed of columns of action data and time stamps 50.

  The user management table 47 is a table including columns of a user ID 51, a user attribute 52 that is a user attribute, and an ID 53 of the behavior data collection device used by the user. In the present embodiment, it is assumed that the user attribute column 52 stores the name of the organization to which the user belongs. In the user terminal column 49, if the user has activated the display software, the IP address of the terminal device is stored. Otherwise, it means that the display software has not been activated. It is assumed that a character string “Login” is stored.

<Procedure for updating behavior data mediation table by terminal device>
The procedure for updating the behavior data mediation table 46 by the terminal device will be described with reference to FIG. In S9, the terminal device starts a timer periodically, for example, every hour, and transmits the self-action data / time stamp to the action data mediating server 11 together with the action data collection device ID in S10.

  The behavior data mediating server 11 that has received the self behavior data time stamp and the behavior data collection device ID in S11 retrieves the corresponding user ID from the user management table 47 in S12, and stores that in the behavior data mediation table 46. The row corresponding to the user ID is searched, and the self-action data / time stamp sequence is updated to the received one. If there is no row corresponding to the received user ID in the behavior data mediating table 46, a new row is created and values are substituted into the user ID column and the self-action data / timestamp column.

  The display software of the terminal device notifies the behavior data collection device ID and the IP address to the behavior data mediating server 11 at an appropriate time, for example, at startup and periodically after startup. By receiving this information, the behavior data mediating server 11 updates the user terminal row in the behavior data mediating table 46. Here, the behavior data mediating server 11 recognizes that the display software is not activated when there is no notification from the display software for a certain period of time. Alternatively, when the display software terminates, the behavior data mediating server 11 is notified of the termination of the software, and the behavior data mediating server 11 receives the notification to recognize that the display software is not activated. good.

<Data structure of other person action data DB according to the present embodiment>
The terminal device refers to the behavior data mediation table 46 to find another terminal device from which the behavior data is to be acquired, acquires the behavior data from the terminal device, and stores it in the other person behavior data DB. First, the structure of the other person behavior data DB will be described with reference to FIG.

  The other person action data DB is composed of three tables: an utterance data table 55, a proximity data table 56, and a face-to-face data table 57 for each row of the other person action data table 54 and the other person action data table. It holds other person behavior data. The other person action data table 54 includes columns of a user ID 58, a time stamp 59, and action data 60. The action data string stores pointers to other person action data.

  The utterance data table 55 stores a copy of the utterance table of the corresponding user's self-action data DB. The proximity data table 56 is a copy of the row in which the user ID of the terminal device is stored in the proximity user ID column 41 in the proximity data table shown in the corresponding user's self-action data DB (FIG. 6). is there. Similarly, the face-to-face data table 57 duplicates the row in which the user ID of the terminal device is stored in the face-to-face user ID column 44 in the face-to-face data table shown in the corresponding user's self-action data DB (FIG. 6). Is.

  The time stamp column 59 stores the self-action data / time stamp held by the terminal device of the corresponding user.

<Procedure for updating other person behavior data DB>
The procedure in which the terminal device acquires the behavior data from another terminal device using the information in the behavior data mediation table 46 and updates the other person behavior data DB (FIG. 9) will be described with reference to FIG.

In S13, the terminal device starts a timer periodically, for example, every hour, and transmits the behavior data collection device ID to the behavior data mediating server 11. In S14 and S20, the behavior data mediator list is sent from the behavior data mediating server 11 to the behavior data sharing server list. Receive. Here, the behavior data sharing list is a table obtained by extracting some rows from the behavior data mediating table 46, in particular, the rows of users related to the user who sent the request. 11 sets the method of this extraction. In the present embodiment, the behavior data mediating server 11 extracts a user row having the same user attribute as the user who requested the behavior data sharer list.
This extraction method determines which terminal devices share behavior data with each other. In the present embodiment, behavior data is shared between users having the same user attribute.

  The terminal device that has received the behavior data sharer list in S14 uses the user ID column and the self-action data / timestamp column in the behavior data sharer list, and the user ID column 58 and the time stamp column in the other person behavior data table, respectively. 59. Specifically, each user ID in the received behavior data sharer list is searched from the other person behavior data table 54, and the time stamp string in the row corresponding to each user ID is updated. Here, the line corresponding to the user ID adds this user ID line to the other person behavior data table 65. According to this procedure, the user ID column of the other person behavior data table 54 is determined when the behavior data sharer list is received for the first time, and does not change thereafter.

  Thereafter, in S15, the following operation is performed on each row of the other person behavior data table 54, that is, each terminal device that wants to share the behavior data. Compare the time stamp of the corresponding row (the row with the same user ID) in the behavior data sharer list received earlier in S16 with the time stamp column 59 of this row, and if the latter is newer (Yes in S16) ), It is determined that the other terminal device corresponding to this row holds new behavior data, and a difference in behavior data is requested from the terminal device in S17. The terminal device transmits this request together with the time stamp 59 of this line and its user ID.

  The terminal device that has received this request in S21 extracts data of the time after the received time stamp from the three tables of the self-action data, and returns it together with the self-action data / time stamp held by itself. The terminal device that has received the request includes the user ID included in the request in the proximity user ID column or the face-to-face user ID columns 41 and 44 from the proximity data table 34 and the face-to-face data table 35 among the self-action data. You may reply by extracting only the line. This is because the terminal device excludes data related to users other than the two users corresponding to the terminal device involved in data transmission / reception from the action data transmitted / received here. In the present embodiment, it is assumed that the terminal device performs this extraction process.

  The terminal device that received the behavior data difference and the new time stamp in S17 adds the behavior data difference of the corresponding row in the other person behavior data table 54 in S18, and received the time stamp 59 in that row in S19. Update to stamp.

<Data structure of physical interaction DB according to the present embodiment>
The terminal device calculates the physical interaction between the user and other users and stores it in the physical interaction DB (FIG. 11). The physical interaction DB is composed of a physical interaction table 67 and a physical interaction table 68 for each user. Here, the physical interaction broadly means a physical interaction between users, such as the time or number of conversations, the time spent living in a specific room, and the like. In the present embodiment, it is assumed that the physical interaction is a conversation between users.

  The physical interaction table 67 is a user ID 69, a time stamp 70 indicating how long the physical interaction corresponding to each row was calculated by action data, and a pointer to the physical interaction table 68 for each user. It is a table comprised from each column of the interaction value 72 which is the value which totaled the interaction 71 and the physical interaction 68 for every user.

<Physical interaction DB update procedure>
The procedure for the terminal device to update the physical interaction DB will be described with reference to FIG. First, after the other person behavior data table 54 is created, the terminal device creates the physical interaction table 67 by adding the user ID column 58 of the other person behavior data table 54 to the physical interaction table.

  After the physical interaction table 67 is created, the terminal device starts a timer periodically, for example, every hour in S22, and repeats the following for the user corresponding to each row of the physical interaction table 67 in S23. To do.

  The physical interaction DB (FIG. 11) is calculated from the behavior data of the two users. In S24, it is determined whether or not this behavior data has been updated from the time when the previous physical interaction was calculated. This determination is made up of two actions: a self-action data time stamp 36 of the self-action data DB (FIG. 6) held by the terminal device, and a time stamp 59 of the corresponding user row of the other person action data DB (FIG. 9). If the older time is compared with the time stamp 70 of the physical interaction DB (FIG. 11), if the former is newer, it is determined that the action data has been updated since the previous update, and the subsequent operations are performed.

  In S25, a physical interaction addition table to be described later is created, and in S26, this is added to the physical interaction table 67. Next, in S27, a physical interaction value is calculated from the physical interaction table 67, and in S28, the time of the corresponding user row in the self-action data / time stamp 36 and the other-party action data DB (FIG. 9) is added to the time stamp. The older value of the stamp 59 is substituted.

<Physical interaction addition table, calculation method of physical interaction>
A physical interaction addition table and a physical interaction calculation method will be described with reference to FIG. In S29, an empty table having the same column as the physical interaction table 67 is prepared. In S30, among the corresponding rows of the self-action data DB (FIG. 6) and the other-party behavior data DB (FIG. 9), the time stamp before the update of all the rows of the respective utterance tables, that is, the physical interaction DB The following is performed for all of the utterance start times that are newer than the time stamp 70.

  In S31, before and after the utterance, the utterance record searched for, for example, between 5 seconds before the utterance start time and 5 seconds after the utterance end time is detected. Here, “detecting the proximity of the other party” means that there is a row including the other party's user ID in the proximity data table 34 of the self-action data DB (FIG. 6) during the above-mentioned time period, This means that a row exists in the proximity data table 56 of the corresponding row in the data DB (FIG. 9). Further, from the set of utterance records (rows) searched in S32, a search is made for those in which the other party's utterance records exist before and after the utterance. All the sets of utterance records (rows) searched in S33 are added to the physical interaction addition table 67.

  The above-described method is a conversation calculation method that uses two conditions that two users are close to each other at a specific time zone and that they are speaking as judgment conditions for having a conversation. . This conversation calculation method may use face-to-face data. For example, you may add the case where facing data is detected to proximity detection. Alternatively, not only the existence of utterances but also a form using utterance patterns (so-called turn-taking) of two users may be used.

  Next, a physical interaction value is calculated from the created physical interaction table and stored in the corresponding physical interaction value 72. The physical interaction value 72 is a value obtained by tabulating physical interactions in a specific period, and in this embodiment, is a cumulative time of conversation volume in the past week.

<Display screen by terminal display software>
FIG. 14 shows an example of a display screen of the display software of the terminal device. This display screen is similar to a display screen of software called IM (instant messenger) that employees can use to confirm each other's presence. A bar graph 80 in FIG. 14 illustrates physical interaction values. Specifically, the physical interaction value between the user of this software and the user corresponding to the user ID 77 displayed on the left side of the bar graph is displayed as the length of the bar graph 80.

  The user ID of the user of the display software is displayed at 75 in FIG. 14, and the other user ID 77 is displayed together with its affiliation name 76. Whether or not the display software for each user is activated is displayed by distinguishing the color of the icon next to the user ID (78 and 79 in FIG. 14). The user can check the presence status of other users by using this icon. The display software displays physical interactions only for users who belong to the same group as the user.

  Hereinafter, how the display software acquires information necessary for display will be described. The display software communicates with the behavior data mediating server 11 as appropriate, and acquires the columns of the user ID 51, the user attribute 52, and the user terminal 49 in the user management table 47 held by the behavior data mediating server 11, The information is displayed as a user ID 77, a user attribute 76, and user presence status 78 and 79, respectively.

  In order to display the bar graph 80, the display software refers to the physical interaction DB (FIG. 11) as appropriate, and for the user registered in the physical interaction table 67, the physical interaction value 72 with the user 69 is displayed. Is set to the length of the bar graph 80. The display software may have a function of registering a person to be displayed and a friend like IM (instant messenger) which is generally used. In that case, when the behavior data mediating server 11 maintains the mutual registration relationship of the users and creates the behavior data sharer list (S20 in FIG. 10), the terminal device that requested the behavior data sharer list. It may be the behavior data mediating server 11 that is created by extracting the user who has registered the user as a friend from the behavior data mediating table 46. By doing so, the behavior data collection system according to the present invention operates so that behavior data is shared between users registered by each user, not the group defined by the organization.

<Uploading self-behavior data>
FIG. 15 shows a GUI (Graphical User Interface) of display software when allowing a user (subject) to upload self-action data to the action data collection server 10.

  When the user clicks the activation button 81, an activation window 82 is displayed. This window explains to the user that the self-behavior data is to be provided to the action data collection server 10, and the action data acquired by the terminal device from the action data collection device to the action data collection server 10 thereafter. It has a select button 84 for selecting to agree to upload. When the user clicks the “Yes” selection button, upload of self-action data is started as described later.

  Here, if a person who intends to collect action data using the action data collection system according to the present invention wants to collect physical interaction between users instead of action data, the terminal device is physically The system may be such that the interaction table is uploaded to the data collection server 10 and the data collection server 10 accumulates it. The activation window (FIG. 15) may not be displayed by a button operation by the user explicitly, but may be configured such that the display software automatically displays this window when a certain time is reached.

<Configuration of behavior data DB held by behavior data collection server>
The behavior data collection server 10 receives behavior data from the terminal device and holds it in the behavior data DB. This behavior data DB (FIG. 16) has a behavior data table 85 including columns of a user ID 89, a time stamp 90, and behavior data 91. The behavior data column 91 includes an utterance data table 86, a proximity data table 87, Pointers to three tables of the face-to-face data table 88 are stored. In these three tables, the utterance data table 33, the proximity data table 34, and the face-to-face data table 35 of the self-action data DB (FIG. 6) of the corresponding terminal device are stored.

<Transaction procedure of behavior data to the behavior data collection server>
A procedure in which the terminal device transmits the behavior data to the behavior data collection server 10 will be described with reference to FIG. In S34, the terminal device starts a timer periodically (for example, every hour), and transmits the self-action data together with the self-action data / time stamp in S35. Here, as the self-action data to be transmitted, only the data acquired after the time of the last transmission, that is, the difference after the time of the previous transmission is transmitted. Specifically, before performing this transmission, the terminal device acquires the time stamp 90 held by the action data collection server 10 and transmits the self-action data after that time stamp together with the latest self-action data / time stamp. To do.

  In S 36, the behavior data collection server 10 stores the received self-behavior data in each of the behavior data tables 86, 87, 88, and stores the received self-behavior data / time stamp in the time stamp column 90.

  Here, the self-behavior data held by the terminal device may be anything as long as it is a memory area managed by the user of the terminal device. For example, the self-action data may exist in a file server on the network. Such a file server on the network may exist in the same device as the behavior data collection server 10, and in this case, transmission of the self-action data to the data collection server 10 (S35, S36) is transmitted to the network. The self-behavior data may not be transmitted, and the access right of the storage area holding the self-behavior data of the file server exclusively owned by each user may be given to the person who collects the data.

  After the user permits data collection through the activation window, the self-behavior data of each user is accumulated in the behavior data collection server 10. The display part of the display software allows the user to deepen their understanding of how the behavior data collection device and behavior data are applied. In addition, the display portion of the display software allows the user to check the frequency of recent conversations with people in the group to which the user belongs and other registered users. If the latter advantage is ignored, the terminal device stops the calculation or display of physical interaction or part or all of the communication processing necessary for the calculation after the user permits uploading of behavior data. It is good also as a form to do.
