     DETAILED DESCRIPTION 
     An exemplary embodiment of the present disclosure will be described below with reference to the drawings. In the drawings, components substantially having identical functions are given the same reference signs, and redundant descriptions thereof are omitted. 
     Exemplary Embodiment 
     Information Processing System  1   
       FIG. 1  illustrates an example of the configuration of an information processing system  1  according to an exemplary embodiment of the present disclosure. The information processing system  1  is applied to a place or an area (also referred to as “activity area” hereinafter) where users P are active. Examples of the activity area include a room (including a rental office and a shared office, and also referred to as “office” hereinafter), a workplace, such as a factory, and a learning place, such as a school or a classroom.  FIG. 1  illustrates a case where the information processing system  1  is applied to an office. 
     As shown in  FIG. 1 , the information processing system  1  includes an information processing apparatus  2 , a behavior-conversation-information acquiring apparatus  3 , a base station  3   a , a biological-information acquiring apparatus  5 , and a network  6 . The behavior-conversation-information acquiring apparatus  3  acquires behavior-related information (also referred to as “behavior data” hereinafter) and conversation-related information (also referred to as “conversation data” hereinafter) of users Pa and Pb. The behavior data and the conversation data may also be collectively referred to as “behavior conversation data” hereinafter. The behavior conversation data will be described in detail later. The base station  3   a  has a function of measuring the distance from the behavior-conversation-information acquiring apparatus  3  by using the radio field intensity. The biological-information acquiring apparatus  5  acquires biologically-related information (also referred to as “biological data” hereinafter) of each of the users Pa and Pb. The network  6  connects the behavior-conversation-information acquiring apparatus  3 , the base station  3   a , the biological-information acquiring apparatus  5  and the information processing apparatus  2  in a communicable manner. 
     The behavior-conversation-information acquiring apparatus  3  and the biological-information acquiring apparatus  5  may be worn by each of the users Pa and Pb or may be disposed distant from each of the users Pa and Pb. The base station  3   a  is fixedly provided at a predetermined position. Of the users Pa and Pb, the one speaking may be referred to as “speaker Pa”, the other may be referred to as “listener Pb”, and both of them may be collectively referred to as “users P”, “participants P” or “members P” if the speaker Pa and the listener Pb are not to be distinguished from each other. Each of the components will be described in detail below. 
     Information Processing Apparatus  2   
       FIG. 2  is a block diagram illustrating an example of a control system of the information processing apparatus  2 . The information processing apparatus  2  is a server apparatus constituted of, for example, a personal computer. The information processing apparatus  2  includes a controller  20  that controls each component, a storage unit  21  that stores various types of data, and a network communication unit  28  that communicates with an external apparatus (such as the behavior-conversation-information acquiring apparatus  3 , the base station  3   a , the biological-information acquiring apparatus  5 , and a terminal apparatus) via the network  6 . 
     Controller  20   
     The controller  20  is constituted of, for example, a processor  20 a, such as a central processing unit (CPU), and an interface. The processor  20 a operates in accordance with a program  210  stored in the storage unit  21  so as to function as, for example, a receiver  200 , a detector  201 , an identifier  202 , an estimator  203 , an aggregator  204 , a determiner  205 , a decider  206 , and a notifier  207 . The components  200  to  207  will be described in detail later. 
     Storage Unit  21   
     The storage unit  21  is constituted of, for example, a read-only memory (ROM), a random access memory (RAM), and a hard disk, and stores therein various types of data, such as the program  210 , communication type information  211  (see  FIGS. 3 and 4 ), communication state information  212  (see  FIG. 5 ), a feedback information table  213  (see  FIG. 6 ), attribute information  214 , and schedule data  215 . 
     The attribute information  214  indicates the attributes of each user P, such as the name, division, business title, social status, rank, and years of experience. The schedule data  215  indicates what kind of schedule each user P may have in a certain period. The communication type information  211 , the communication state information  212 , and the feedback information table  213  will be described in detail later. 
     Network Communication Unit  28   
     The network communication unit  28  is realized by, for example, a network interface card (NIC), and exchanges information and signals with external apparatuses via the network  6 . 
     Components of Controller  20   
     Receiver  200   
     The receiver  200  receives, for example, various types of data, information, and signals transmitted from an external apparatus. In detail, the receiver  200  receives behavior conversation data transmitted from the behavior-conversation-information acquiring apparatus  3 . Moreover, the receiver  200  receives biological data transmitted from the biological-information acquiring apparatus  5 . 
     Detector  201   
     The detector  201  detects a specific signal from the various types of data received by the receiver  200 . For example, the detector  201  detects a signal indicating a speech from the behavior conversation data. Moreover, for example, the detector  201  also detects information related to the detected speech, such as information for identifying the speaker Pa, information for specifying the position of the speaker Pa, and information indicating whether or not a conversation with another participant P is being made. 
     Identifier  202   
     In accordance with the behavior conversation data received by the receiver  200 , the identifier  202  identifies the type (sometimes simply referred to as “type” or “communication type” hereinafter) of a scene where the users P are communicating with each other. 
     In detail, the identifier  202  checks the behavior conversation data against the communication type information  211  stored in the storage unit  21 , so as to identify which region classified in the communication type information  211  the behavior conversation data corresponds to. 
     Examples of the communication type include a type classified in accordance with the characteristics of the communication, such as the scale and mode of the communication, and a type classified in accordance with the situation, such as the purpose, intention, and content of the communication, and the characteristics of the participants. The type classified in accordance with the characteristics of the communication includes, for example, “interview and discussion”, “discussion”, “report (or lecture)”, and “presentation”. The type classified in accordance with the situation includes, for example, “a situation where many participants are meeting for the first time”, “brainstorming of ideas”, and “team meeting”. 
     Examples of data used for identifying the communication type include the length of a speech by a participant P and the number of times and the frequency of a speech (also referred to as “speech amount” hereinafter), the evenness (also referred to as “balance” hereinafter) in the speech amount if there are multiple participants P, information derivable from the behavior conversation data, such as the number of participants P, the attribute information  214  of each participant P, and pre-recorded information, such as the schedule data  215  indicating the schedule of each participant P. The information derivable from the behavior conversation data may be calculated by the identifier  202  from the behavior conversation data. 
     Estimator  203   
     The estimator  203  estimates how each participant P is feeling about the communication, that is, the internal state (also referred to as “communication state” hereinafter) that each participant P has with respect to the communication. 
     In detail, the estimator  203  estimates the communication state by checking internal information (to be described later) of each participant P obtained from the behavior conversation data and the biological data against the communication state information  212  stored in the storage unit  21  and by identifying which region classified in the communication state information  212  the behavior conversation data and the biological data correspond to. 
     The communication state is expressed with items including an expression indicating a subjective view, such as how a user P feels about the communication, and an expression indicating an action taken by the user P. In detail, the communication state is expressed with items, such as “listening with interest”, “immersed in conversation”, and “speaking with anger” (see  FIG. 5 ). 
     The internal state of a user P includes, for example, the mental state, the psychological state, and the emotional state of the user P. Examples of the internal state of a user P include “pleasantness/unpleasantness” indicating whether the user P tends to be in a pleasant state or tends to be an unpleasant state, “stress” indicating a psychological load on the user P, and “emotion” indicating the emotions of the user P. 
     The “pleasantness/unpleasantness”, “stress”, and “emotion” expressing the internal state of each user P may be evaluated by using a quantitative indicator. This indicator is obtained by analyzing the biological data of each user P. This analysis may be performed by the estimator  203 . 
     Aggregator  204   
     The aggregator  204  aggregates communication states. In detail, the aggregator  204  aggregates the communication state estimated for each user P by the estimator  203 , so as to determine the communication state in the group where the communication is carried out. 
     For example, the aggregator  204  performs an aggregation for determining what proportion of members P in a specific communication state is occupying the group or for determining whether a member P having any of the communication states is mixed in the group. The “proportion” may be qualitative information, such as “mostly A”. 
     Determiner  205   
     The determiner  205  determines whether the communication is good or poor (also referred to as “communication quality” hereinafter) in accordance with the communication type and the communication state. The criterion for determining whether the communication is “good” or “poor” may be set in advance. 
     In detail, the determiner  205  checks the communication type identified by the identifier  202  and the communication state estimated by the estimator  203  against the feedback information table  213  stored in the storage unit  21 , so as to extract the corresponding quality, thereby determining the communication quality. 
     Moreover, the determiner  205  determines whether or not a prescription (also referred to as “feedback” hereinafter) is necessary in accordance with the communication type and the communication state. 
     Decider  206   
     If the determiner  205  determines that feedback is necessary, the decider  206  decides on the contents and method of the feedback in accordance with the communication type and the communication state. 
     In detail, the decider  206  checks the communication type identified by the identifier  202  and the communication state estimated by the estimator  203  against the feedback information table  213  stored in the storage unit  21 , thereby deciding on the corresponding contents and method of the feedback. 
     Notifier  207   
     The notifier  207  performs the feedback in accordance with the decision made by the decider  206 . 
     Information and Table Stored in Storage Unit  21   
     Communication Type Information  211   
       FIG. 3  illustrates an example of the communication type information  211 . The communication type information  211  is used for identifying the communication type from behavior conversation data. In detail, in the communication type information  211 , at least one type of information (i.e., parameter) for identifying the communication type and a numerical range corresponding to the parameter are recorded in the form of, for example, a table. For illustrative purposes, each of  FIGS. 3 and 4  is a visualized map showing two types of parameters for identifying the communication type in a plane constituted of two orthogonal coordinate axes. 
     As shown in  FIG. 3 , communication types are classified in accordance with, for example, the group characteristics and the conversation characteristics during communication. The group characteristics correspond to, for example, the number of members P forming the group (i.e., participants P of the communication). The conversation characteristics correspond to, for example, an indicator indicating whether the conversation is dynamic or static, that is, whether the speaker Pa is limited to a specific participant P. 
     In detail, in a case where the group characteristics correspond to a small number of people and the conversation characteristics correspond to a dynamic conversation (region I), such a case corresponds to “interview and discussion” as a communication mode in which the speaker changes frequently between a small number of people. In a case where the group characteristics correspond to a large number of people and the conversation characteristics correspond to a dynamic conversation (region II), such a case corresponds to “discussion” as a communication mode in which the speaker changes frequently among a large number of people. 
     In a case where the group characteristics correspond to a small number of people and the conversation characteristics correspond to a static conversation (region III), such a case corresponds to “report” or “lecture” as a communication mode in which a specific participant P tends to be speaking between a small number of people. In a case where the group characteristics correspond to a large number of people and the conversation characteristics correspond to a static conversation (region IV), such a case corresponds to “presentation” as a communication mode in which a specific participant P tends to be speaking among a large number of people. 
       FIG. 4  illustrates another example of the communication type information  211 . As shown in  FIG. 4 , communication types may be classified by using continuity as the group characteristics indicating whether the group is temporary or ongoing. 
     In detail, a case where the group is temporary (region V) corresponds to communication in a situation where many participants P are meeting for the first time. A case where the group is ongoing (region VI) corresponds to communication in a situation with certain collectivity, as in a team meeting. 
     A case of dynamic conversation characteristics (region VII) corresponds to communication intended for giving out ideas among participants P, as in brainstorming. A case of static conversation characteristics (region VIII) corresponds to communication such as a presentation. 
     Sections where the aforementioned regions V to VIII overlap correspond to communication having the characteristics of the corresponding regions. For example, a case of temporary group characteristics and dynamic conversation characteristics (V and VI) corresponds to communication in a situation where many participants P are meeting for the first time and are brainstorming for giving out ideas. Detailed descriptions for combinations other than the combination of V and VI will be omitted. 
     Communication State Information  212   
       FIG. 5  illustrates an example of the communication state information  212 . The communication state information  212  is used for identifying the communication state for each member P. In detail, in the communication state information  212 , at least one type of parameter for identifying the communication state and a numerical range corresponding to the parameter are recorded in the form of, for example, a table. Similar to  FIGS. 3 and 4 , for illustrative purposes,  FIG. 5  is a visualized map showing two types of parameters for identifying the communication state in a plane constituted of two orthogonal coordinate axes. 
     As shown in  FIG. 5 , communication states are classified in accordance with, for example, a speech amount of each participant P and an evaluation value indicating “pleasant” or “unpleasant” as an example of an indicator indicating the internal state of the participant P. Furthermore, examples of the classified communication states include six states, namely, “A: listening with interest”, “B: immersed in conversation”, “C: being bystander, indifferent”, “D: speaking in a businesslike manner”, “E: not able to speak one&#39;s thoughts”, and “F: speaking with anger”. The number and the contents of the classified items are not limited to the above. 
     In detail, the communication state is classified as a “listening” state or a “speaking” state as an action in accordance with the speech amount, and is classified as an active state with an interested or immersed mindset or as a passive state with an oppressed, pressured, tolerating, or angry mindset, in accordance with the internal state. 
     In more detail, for example, if the speech amount tends to be small and the internal state tends to be “unpleasant”, the communication state is classified as a state where a participant P is oppressed from speaking due to certain pressure and is listening one-sidedly, that is, the state of “E: not able to speak one&#39;s thoughts”. As another example, if the speech amount tends to be large and the internal state tends to be “pleasant”, the communication state is classified as the state of “B: immersed in conversation”. 
     Feedback Information Table  213   
       FIG. 6  illustrates an example of the feedback information table  213 . The feedback information table  213  is used for determining the communication quality and for identifying the contents and method of feedback by pairing the communication type and the communication state. 
     The feedback information table  213  is provided with a “communication type” field, an “ideal state of member(s)” field, an “actual state of member(s)” field, a “communication quality” field, an “assumed situation” field, and a “prescription (feedback)” field. Among these fields, the “communication type” field and the “actual state of member(s)” field have input values therein, whereas the “communication quality” field and the “prescription (feedback)” field have output values therein in accordance with the input values. Reference signs “A” to “F” indicated in the fields respectively correspond to “A” to “F” defined in the communication state information  212  shown in  FIG. 5 . 
     In the “communication type” field, the communication types mentioned above are recorded.  FIG. 6  exemplarily lists only the regions I to IV described with reference to  FIG. 3 . 
     In the “ideal state of member(s)” field, a predetermined ideal communication state is recorded for each communication type. For example, if the communication type is “interview” or “discussion”, the state of “B: immersed in conversation” shown in  FIG. 5  is defined as being an ideal state. 
     In the “actual state of member(s)” field, the communication state of the members P is recorded. Examples of information recorded in the “actual state of member(s)” field include “mostly B” (i.e., the communication state of most members P among the members P forming the group is the state of “B: immersed in conversation”), “mostly A” (i.e., the communication state of most members P among the members P forming the group is the state of “A: listening with interest”), and “F and E” (i.e., there is a mixture of members P in the state of “E: not able to speak one&#39;s thoughts” and members P in the state of “F: speaking with anger” in the group). These pieces of information are checked against information obtained by the aggregator  204  qualitatively aggregating, for each group, the communication state estimated for each member P by the estimator  203 . 
     In the “communication quality” field, information indicating the communication quality is recorded. Examples of the information indicating the communication quality include “very good”, “slightly poor”, “poor”, and “very poor”. 
     The communication quality does not necessarily have to be classified into four levels as in the above example, and may be classified into two levels or three levels, or may be classified in more detail into five or more levels. Alternatively, the communication quality may be expressed quantitatively by using a numerical value. 
     Information recorded in the “assumed situation” field indicates the type of situation occurring in the communication and assumed when the communication state is the state recorded in the “actual state of member(s)” field. 
     Information recorded in the “prescription (feedback)” field indicates the contents and method of feedback to be performed in accordance with the communication quality. Examples of the information recorded in the “prescription (feedback)” field include “prompt A to make statement” (i.e., prompt a member P in the state of “A: listening with interest” among the members P forming the group to make a statement) and “prompt F to calm down” (i.e., prompt a member P in the state of “F: speaking with anger” among the members P forming the group to calm down). In the table, reference symbol “-” indicates that feedback is not particularly necessary. 
     Operation According to Exemplary Embodiment 
       FIG. 7  is a flowchart illustrating an example of the operation of the information processing apparatus  2  according to the exemplary embodiment of the present disclosure. In step S 1 , the receiver  200  receives behavior conversation data acquired by the behavior-conversation-information acquiring apparatus  3  and transmitted to the information processing apparatus  2 . In step S 2 , the detector  201  detects a signal indicating a speech from the behavior conversation data. 
     When the detector  201  detects a speech from the behavior conversation data (YES in step S 2 ), the identifier  202  identifies a group formed by members P who are speaking, and identifies the number of members P forming the group (sometimes simply referred to as “number of people in the group” hereinafter) in step S 3 . 
     Then, in step S 4 , the identifier  202  identifies the communication type. In this case, the identifier  202  may refer to the attribute information  214  and the schedule data  215  stored in advance in the storage unit  21 . 
     In step S 6 , the receiver  200  receives biological information, acquired by the biological-information acquiring apparatus  5  and transmitted to the information processing apparatus  2 , related to each of the members P forming the group. The estimator  203  determines the internal state of each member P in accordance with, for example, the biological information in step S 7 , and estimates the communication state of each member P in accordance with, for example, the internal state in step S 8 . 
     The process from step S 6  to step S 8  involving the reception of the biological information by the receiver  200  and the determination of the internal state and the estimation of the communication state by the estimator  203  is performed on all of the members P in the group (YES in step S 5 ). 
     Subsequently, in step S 9 , the aggregator  204  aggregates the communication state of each member P so as to determine the communication state of the group. In step S 10 , the determiner  205  refers to the feedback information table  213  so as to determine the communication quality according to the communication type and the communication state. 
     In step S 11 , the determiner  205  further determines whether or not feedback is necessary by referring to the feedback information table  213 . If the determiner  205  determines that feedback is necessary (YES in step S 11 ), the decider  206  refers to the feedback information table  213  so as to decide on the contents and method of feedback in step S 12 . 
     In step S 13 , the notifier  207  performs feedback in accordance with the decision by the decider  206 . 
     Behavior-Conversation-Information Acquiring Apparatus  3   
       FIG. 8  illustrates an example of the configuration of the behavior-conversation-information acquiring apparatus  3 . The behavior-conversation-information acquiring apparatus  3  acquires information related to a behavior and a speech or conversation. 
     As shown in  FIG. 8 , for example, the behavior-conversation-information acquiring apparatus  3  includes a base unit  30  equipped with a sensor that acquires conversation data, and also includes a strap  31  for securely retaining the base unit  30  to a position close to the body of a user P. For example, the behavior-conversation-information acquiring apparatus  3  is used by being hung from the neck of the user P. 
     The base unit  30  includes multiple microphones  301  and  302  that are disposed at different distances from the mouth of the user P in a state where the strap  31  is hung from the neck of the user P. In detail, the multiple microphones  301  and  302  include a first microphone  301  provided on the strap  31  and a second microphone  302  provided in the base unit  30 . 
     Accordingly, the multiple microphones  301  and  302  are provided at different distances from the mouth of the user P in this manner. Thus, when a voice output by the user P is detected, a time lag occurs in the speech detection timings, whereas when a voice output by a third person is detected, such a time lag in the speech detection timings is minimized. The behavior-conversation-information acquiring apparatus  3  utilizes this principle to distinguish and identify the voices of first and third persons from each other. 
     Furthermore, the behavior-conversation-information acquiring apparatus  3  measures the distance between multiple base stations  3   a  so as to identify the position and the behavior of the user P. 
     In this exemplary embodiment, the behavior-conversation-information acquiring apparatus  3  may be of any type that is capable of acquiring information about the position and the speech of the user P, and may be, for example, a detector that contains a camera and a directional microphone. 
       FIGS. 9A to 9C  illustrate an example of detection of a conversation by behavior-conversation-information acquiring apparatuses  3 . Specifically,  FIG. 9A  illustrates an example of activities of users P in a meeting room, and  FIGS. 9B and 9C  are timing charts illustrating examples of signals obtained from the behavior-conversation-information acquiring apparatuses  3 . Although the actual users P are individually wearing the behavior-conversation-information acquiring apparatuses  3 , the behavior-conversation-information acquiring apparatuses  3  are not shown in  FIG. 9A . 
     As shown in  FIG. 9A , it is assumed that multiple (e.g., six) users P are active in the activity area, such as a meeting room R. It is assumed that two of the multiple users P (i.e., “A” and “B”) are having a conversation. 
     In this case, the behavior-conversation-information acquiring apparatuses  3  acquire signals as shown in  FIGS. 9B and 9C . With regard to the ordinate axis, “ON” denotes a state where a user is speaking, whereas “OFF” denotes a state where the user is not speaking. For example, in a case where two different people are conversing with each other, the signals obtained each indicate that the speaking state alternately appears, as shown in  FIGS. 9B and 9C . 
     Biological-Information Acquiring Apparatus  5   
       FIG. 10  illustrates an example of the configuration of the biological-information acquiring apparatus  5 . For example, the biological-information acquiring apparatus  5  measures biological data of a user P in the activity area when the user P is active. The biological-information acquiring apparatus  5  may measure the biological data not only when the user P is active but also when, for example, the user P is in an inactive state, such as when the user P is lying down, napping, or sleeping. 
     The biological data is released from a biological body and may include any of the following examples: 
     a. information indicating a body motion (e.g., acceleration caused by a body motion, a pattern indicating a behavior, and so on); 
     b. an amount of activity (e.g., the number of steps taken, consumed calories, and so on); and 
     c. vital information (e.g., the heart rate, the pulse wave, the pulse rate, the respiration rate, the body temperature, the blood pressure, and so on). 
     In this exemplary embodiment, the biological-information acquiring apparatus  5  particularly measures, for example, data related to the balance of the autonomic nervous system, such as a heartbeat interval (e.g., seconds or milliseconds), a low-frequency component (LF), and a high-frequency component (HF). 
     The biological-information acquiring apparatus  5  is desirably of a wearable type worn on the body of the user P. In this exemplary embodiment, the biological-information acquiring apparatus  5  is of a wristband type worn on a wrist, as shown in  FIG. 10 . The biological-information acquiring apparatus  5  includes a base unit  51  and a wearable unit  52 . The base unit  51  includes a sensor unit  510  equipped with various types of sensors and also includes an operation display  511  used for displaying measured data, inputting information, and performing operations. The wearable unit  52  is formed of a belt to be worn on the wrist. The sensor unit  510  acquires various types of biological data from the body, which is in contact with the base unit  51 , at a predetermined timing or cycle. The sensor unit  510  includes, for example, an accelerometer that measures a body motion. 
     The biological-information acquiring apparatus  5  is not limited to a wristband type and may be of any type capable of acquiring biological data. Examples of the biological-information acquiring apparatus  5  include a ring type worn on a finger, a belt type worn on the waist, a shirt type that is worn on the upper body and comes into contact with, for example, the left and right arms, the shoulders, the chest, and the back, a head type that covers the head, an eyeglasses type or a goggle type worn on the head, an earphone type worn on an ear, and an attachable type attached to a part of the body. Furthermore, the biological-information acquiring apparatus  5  does not necessarily have to be worn on the body and may be, for example, a camera having a function for measuring the heart rate by capturing the absorption of light by hemoglobin. 
     Network  6   
     The network  6  is a communication network, such as a local area network (LAN), a wide area network (WAN), the Internet, or an intranet, and may be a wired network or a wireless network. 
     First Modification 
       FIG. 11  is a block diagram illustrating an example of a control system of an information processing apparatus  2  according to a first modification. The information processing apparatus  2  according to this modification is different from the information processing apparatus  2  according to the above exemplary embodiment in that the information processing apparatus  2  further includes a calculator  208 . Components having configurations and functions identical to those in the above exemplary embodiment are given the same reference signs, and detailed descriptions thereof will be omitted. Moreover, the following description focuses on differences from the information processing apparatus  2  according to the above exemplary embodiment. 
     As shown in  FIG. 11 , the processor  20 a in the information processing apparatus  2  according to this modification further functions as the calculator  208 , in addition to the components  200  to  207  described in the above exemplary embodiment. 
     The calculator  208  aggregates the communication quality in accordance with a predetermined calculation method (i.e., an algorithm) for each team, so as to calculate an index (also referred to as “communication index” or “team communication quality index (TCQI)”) for comprehensively determining the communication state of the team. 
     Furthermore, the calculator  208  further analyzes a tendency (also referred to as “trend” hereinafter) of a temporal variation in the TCQI, and outputs the communication state of the team in a visualized form. Moreover, when the TCQI crosses a predetermined threshold value, the calculator  208  outputs a warning indicating that the communication state has deteriorated. 
       FIG. 12  schematically illustrates an example of a variation in the communication quality in a team. The ordinate axis denotes the TCQI. In this case, a larger value is defined as “good”, whereas a smaller value is defined as “poor”. The abscissa axis denotes a time axis indicated in units of, for example, “days”. 
     As shown in  FIG. 12 , when the communication state in the team gradually deteriorates, the TCQI decreases with time (see an arrow “Y 1 ”). When this TCQI falls below the predetermined threshold value, the calculator  208  outputs a warning. 
     Assuming that certain feedback is performed after the warning is output and the communication state in the team is improved, the TCQI increases again (see an arrow “Y 2 ”). The TCQI subsequently continues to increase for a certain period, and then may tend to decrease again (see an arrow “Y 3 ”). In such a case, when the TCQI falls below the predetermined threshold value again, the calculator  208  outputs a warning again. The feedback in this case is not necessarily limited to the contents recorded on the feedback information table  213  shown in  FIG. 6 . For example, a principal member of the team may be prompted to have a one-on-one conversation with another member or to provide an opportunity to have a conversation within the team. 
     Second Modification 
     With regard to the communication state of a team, for example, an amount S indicating a “scene status” evaluated based on distribution of amounts of speech and levels of stress (also referred to as “stress levels” hereinafter) may be used as an indicator. A stress indicator may be determined from biological data of a speaker Pa. The stress indicator used here is a value obtained by dividing a low-frequency component (LF) of a heart beat by a high-frequency component (HF). Stress is an example of the internal state of the speaker Pa. 
     The amount S indicating the scene status may be determined by using, for example, Expression (1) indicated below: 
       amount  S  indicating scene status=VAR (speech amount)×AR (stress/speech amount)   (1)
 
     where “VAR” is a function expressing the degree of distribution and is used for calculating an evaluation value. With regard to the “VAR”, it is assumed that the evaluation value is output in three levels, namely, large, medium, and small, with respect to the speech amount, and is output in three levels, namely, high, medium, and low, with respect to “stress/speech amount”. 
     With regard to the value of S, the smaller the value, the better the scene status, and the larger the value, the poorer the scene status. The “stress/speech amount” is a value obtained by normalizing the stress indicator based on the speech amount, and may be, for example, a value obtained by dividing the stress indicator by the speech amount. The “stress/speech amount” is an example of a stress level. 
       FIGS. 13A to 13C  illustrate examples of the scene status (S). Specifically,  FIG. 13A  illustrates an example of a good status,  FIG. 13B  illustrates an example of an intermediate status, and  FIG. 13C  illustrates an example of a poor status. As shown in  FIG. 13A , in a case where the evenness in the speech amounts and the evenness in the stress levels among the participants P are both high, the value of S is small, that is, indicates a good status. 
     As shown in  FIG. 13B , in a case where the evenness in the speech amounts among the participants P is low but the stress levels are about the same, the value of S is an intermediate value, that is, indicates an intermediate status. 
     As shown in  FIG. 13C , in a case where the evenness in the speech amounts and the evenness in the stress levels among the participants P are both low, the value of S is large, that is, indicates a poor status. 
     Third Modification 
       FIG. 14  is a table collectively illustrating a specific example of the behavior-conversation-information acquiring apparatus  3  and the biological-information acquiring apparatus  5 . The behavior-conversation-information acquiring apparatus  3  and the biological-information acquiring apparatus  5  are not limited to those described in the above exemplary embodiment. As shown in  FIG. 14 , the behavior-conversation-information acquiring apparatus  3  used may be of a non-wearable type, such as a camera having an image recognition function. 
     Although the exemplary embodiment of the present disclosure has been described above, the exemplary embodiment of the present disclosure is not limited to the above exemplary embodiment, and various modifications are permissible so long as they do not depart from the scope of the disclosure. For example, the variations of “communication type” are not limited to those mentioned above. For example, the communication type may be identified by using only a single type of parameter (e.g., only the number of people or the conversation characteristics) instead of using two types of parameters. Moreover, the “communication type” is not necessarily limited to information identified by the identifier  202  and may alternatively be manually-input information. 
     Each component of the controller  20  may partially or entirely be constituted of a hardware circuit, such as a Field Programmable Gate Array (FPGA) or an Application Integrated Circuit (ASIC). 
     Furthermore, one or some of the components in the above exemplary embodiment may be omitted or changed. Moreover, in the flowchart in the above exemplary embodiment, for example, a step or steps may be added, deleted, changed, or interchanged within the scope of the disclosure. The program used in the above exemplary embodiment may be provided by being recorded on a computer readable recording medium, such as a compact disc read-only memory (CD-ROM). Alternatively, the program used in the above exemplary embodiment may be stored in an external server, such as a cloud server, and may be used via a network. 
     In the exemplary embodiment above, the term “processor” refers to hardware in a broad sense. Examples of the processor include general processors (e.g., CPU: Central Processing Unit) and dedicated processors (e.g., GPU: Graphics Processing Unit, ASIC: Application Integrated Circuit, FPGA: Field Programmable Gate Array, and programmable logic device). 
     In the exemplary embodiment above, the term “processor” is broad enough to encompass one processor or plural processors in collaboration which are located physically apart from each other but may work cooperatively. The order of operations of the processor is not limited to one described in the exemplary embodiment above, and may be changed.
