Hereinafter, embodiments of the user state estimation device according to the present invention will be described in detail together with the drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate description will be omitted.

FIG. 1 shows a server 10 which is a user state estimation device according to the present embodiment. The server 10 is a device (system) that estimates the state of the user of the terminal 20. The server 10 estimates based on the information transmitted from the terminal 20.

Specifically, the server 10 estimates the user's mental state (mental health state) from the reply (reply) status of e-mail or the like. As mentioned above, when the user's mental state deteriorates, the behavior may be postponed. In this embodiment, the above estimation is performed depending on whether or not the user has postponed the reply.

The terminal 20 is a device used by the user. Specifically, the terminal 20 corresponds to a mobile phone, a smartphone, or the like carried by the user. Alternatively, the terminal 20 may be a PC (personal computer). The terminal 20 has a function of connecting to a mobile communication network or a network such as the Internet for communication. The terminal 20 and the server 10 can communicate with each other via a network, and can send and receive information to and from each other.

In addition, the terminal 20 can communicate with other terminals via the network. Specifically, the terminal 20 can send and receive e-mails, messages, and the like, and make telephone calls (voice calls) and the like with other terminals. Sending and receiving messages, for example, chatting may be performed by a dedicated application (hereinafter, referred to as an application) installed on the terminal 20. The terminal 20 transmits the communication history related to the above communication to the server 10. For e-mails or messages, the transmitted communication history is a transmission / reception history including the time of transmission / reception and information indicating the terminal of the transmission / reception partner (for example, the mail address and ID of the terminal of the other party). As for the telephone, the transmitted communication history is the incoming / outgoing call history including the time of incoming / outgoing call and the information indicating the terminal of the incoming / outgoing call partner (for example, the telephone number of the other party's terminal). In addition to the above, the communication history may include information used for processing in the server 10, such as information that enables determination of a reply, which will be described later. The communication history may be transmitted, for example, once a day at a preset time (for example, 0:00).

A reply to an e-mail or message is, for example, sending an e-mail or message to the person receiving the e-mail or message. In addition, in the e-mail, the case where the e-mail is sent to the specific received e-mail may be a reply. In this case, if a new e-mail is sent to the person who received the e-mail, no reply will be sent. The reply to the telephone is, for example, to make a call to the person who received the missed call.

The terminal 20 is configured to include hardware such as a CPU (Central Processing Unit), a memory, and a communication module in the same manner as a normal mobile phone, smartphone, PC, or the like.

Subsequently, the function of the server 10 according to the present embodiment will be described. As shown in FIG. 1, the server 10 includes a communication history acquisition unit 11, a user status detection unit 12, a reply status identification unit 13, an estimation unit 14, and an output unit 15.

The communication history acquisition unit 11 is a functional unit that acquires the communication history of the user's terminal 20. The communication history acquisition unit 11 receives and acquires the communication history transmitted from the terminal 20. The communication history acquisition unit 11 outputs the acquired communication history to the reply status specifying unit 13.

The user status detection unit 12 is a functional unit that detects the status of the user that may affect the reply. The user status detected by the user status detection unit 12 is whether or not the user can reply to another terminal. The situation in which the user cannot reply includes the situation in which the user is unaware of the reception to be replied to. The user status detection unit 12 detects the user status for each time (time zone). The user situation detection unit 12 acquires the situation detection information used for detecting the user's situation, and detects the user's situation based on the situation detection information. For example, the user status detection unit 12 detects the user status as follows.

The user status detection unit 12 acquires information indicating the user's schedule and detects the status of the user. The user status detection unit 12 receives and acquires the information from the terminal 20. Alternatively, the user status detection unit 12 acquires the information from the server that manages the information. An example of the information is shown in FIG. As shown in FIG. 2, the information is information associated with date, time, and schedule contents. The date and time are information indicating a time zone related to the schedule. The schedule content is information indicating the content of the schedule, for example, information such as a meeting or a hospital.

The user status detection unit 12 detects that the time zone indicated by the date and time is not a situation in which the user can reply in communication with another terminal. Alternatively, the user status detection unit 12 indicates that the schedule content is a predetermined one, for example, when the schedule content is in a meeting, hospital, or driving, the date and time associated with the schedule content. Detects that the time zone is not available for reply.

Alternatively, the user situation detection unit 12 acquires information indicating the behavior of the terminal 20, and estimates and detects the user's situation based on the information indicating the behavior. For example, the user situation detection unit 12 is based on the behavior of the terminal 20, that the user is sleeping, the terminal 20 is not in the user's hand, that he / she is in a specific vehicle (for example, a car or a motorcycle), and Detects whether the user is in business (work) or private.

The situation where the user is sleeping is not the situation where a reply is possible. The user status detection unit 12 estimates that the user is sleeping, for example, by the conventional technique described in Japanese Patent Application Laid-Open No. 2012-235942. Therefore, the user status detection unit 12 receives information from the terminal 20 as information indicating the behavior of the terminal 20 that is detected by a sensor that detects the body movement of the user provided in the terminal 20 and information that indicates the time related to the detection. To get. The user status detection unit 12 estimates that the user is sleeping based on the information received from the terminal 20. The user status detection unit 12 detects that the time zone is not a status in which a reply is possible.

A situation in which the user does not have the terminal 20, such as when the terminal 20 is left on the desk and goes out, is not a situation in which a reply is possible. The user situation detection unit 12 estimates a situation in which such a terminal 20 is not at hand. In that case, for that purpose, the user status detection unit 12 turns on the information detected by the sensor provided in the terminal 20, the (display) screen provided in the terminal 20, as the information indicating the behavior of the terminal 20 from the terminal 20. The information indicating OFF and the information indicating those times are acquired. The sensor is a sensor that detects the movement of the terminal 20, such as an acceleration sensor, a tilt sensor, and a gyro sensor.

The terminal 20 includes a screen. Normally, when the terminal 20 is operated by the user, the terminal 20 turns on the screen (a state in which the screen is displayed). Further, the terminal 20 turns off the screen (a state in which the screen is not displayed) if there is no operation from the user for a certain period of time. Therefore, ON and OFF of the screen indicate the operation state of the user.

In the user status detection unit 12, the change in the value of each sensor is equal to or less than a preset threshold value for a certain period (for example, 30 minutes or 1 hour), and the screen is turned on and off when the user does not operate the terminal 20. (For example, when the screen is OFF), it is estimated that the terminal 20 is not in the user's hand. The user status detection unit 12 detects that the time zone is not a status in which a reply is possible.

The situation where the user is in a specific vehicle such as a car or a motorcycle is not a situation in which a reply can be made. The user status detection unit 12 estimates whether the user is in a vehicle or is walking by using a conventional technique such as Activity Recognition provided by Google. Therefore, the user situation detection unit 12 acquires from the terminal 20 the information used in the above-mentioned prior art detected by the terminal 20 and the information indicating the time related to the detection as the information indicating the behavior of the terminal 20. The user status detection unit 12 estimates whether the user is in a vehicle or is walking based on the information received from the terminal 20.

Further, in addition to the above information, the user situation detection unit 12 acquires information indicating the position of the terminal 20 from the terminal 20 as information indicating the behavior of the terminal 20. The information indicating the position of the terminal 20 is obtained by the positioning function of the own terminal 20 such as the GPS (Global Positioning System) positioning function of the terminal 20, and is information such as latitude and longitude. When it is estimated that the user is in a vehicle, the user status detection unit 12 determines whether or not the position of the terminal 20 at that time is on the road. The user status detection unit 12 makes the determination using, for example, the map information stored in advance. When the user status detection unit 12 determines that the position of the terminal 20 is on the road, it presumes that the user is in a specific vehicle such as a car or a motorcycle. The user status detection unit 12 detects that the time zone is not a status in which a reply is possible. Here, the driver and the passenger are not distinguished, and it is detected that the situation is not such that a reply can be made in any case.

In addition, when it is estimated that the user is on a vehicle other than a specific vehicle such as a car or a motorcycle, for example, a train (when it is determined that the position of the terminal 20 is not on the road), a reply is possible. Is said to be. The user status detection unit 12 outputs information indicating a time zone estimated that the reply is not possible to the reply status identification unit 13.

As shown in the table of FIG. 3, depending on whether the user is in business or in private, there are some that can reply to the received e-mail and the like and some that cannot. The user status detection unit 12 may estimate whether the user is in business or in private, for example, as follows. Therefore, the user situation detection unit 12 acquires from the terminal 20 information indicating the position of the terminal 20 and information indicating the times thereof as information indicating the behavior of the terminal 20. The user status detection unit 12 determines whether or not the position indicated by the acquired information is within a certain range (for example, an area having a radius of 500 m from the position of the workplace) from the preset position of the user's workplace. .. When the user status detection unit 12 determines that the position of the terminal 20 is within the range, it estimates that the user is in business at that time. On the other hand, if the user status detection unit 12 determines that the position of the terminal 20 is not within the range, the user presumes that the user is private at that time.

The position of the user's workplace may be estimated by, for example, the prior art described in Japanese Patent Application Laid-Open No. 2017-059032. Further, the estimation of whether the user is in business or in private may be performed by a method other than the above, for example, a method based on the user's schedule. The user status detection unit 12 outputs information indicating at least one of the estimated business time zone and the private time zone to the reply status identification unit 13.

The reply status specifying unit 13 is a functional unit that identifies the reply status of the user based on the communication history acquired by the communication history acquisition unit 11 and the user status detected by the user status detection unit 12. The reply status specifying unit 13 specifies the reply status of the user by calculating the time obtained by subtracting the non-reply time indicated by the user's situation from the time from reception to reply indicated by the communication history. The reply status specifying unit 13 specifies the reply status of the user only for a predetermined communication based on the reply target. The reply status specifying unit 13 specifies the reply status of the user for each type of reply target. The reply status specifying unit 13 specifies the reply status of the user for each time zone.

For example, the reply status specifying unit 13 specifies the reply status of the user as follows. The reply status specifying unit 13 inputs the communication history from the communication history acquisition unit 11 and the information indicating the time zone estimated that the reply is not possible from the user status detection unit 12. The reply status specifying unit 13 refers to the communication history and determines whether or not a reply has been made to the reception of the e-mail and the message and the incoming call. This determination can be made by a known method based on the information included in the communication history (for example, information indicating the terminal of the other party, the title of the e-mail, the meta information of the e-mail).

Based on the above determination, the reply status specifying unit 13 specifies the reception (incoming call, the same applies hereinafter) time and the reply time from the communication history for each received e-mail and message and the received telephone call. The identified information is, for example, the information shown in FIG. As shown in FIG. 4, the information is information in which a date, a reception time, a reply time, and a usage tool (communication tool) are associated with each other. The date, reception time, and reply time are information indicating the time when the reception and reply were made. If no reply is made to the reception, the reply time information is not included. The tool used indicates the tool that received and replied, that is, the distinction between e-mail, application, and telephone. In this way, the usage tool indicates the type of reply target.

The reply status specifying unit 13 subtracts the time in the time zone estimated that the reply indicated by the information input from the user status detection unit 12 is not possible from the time from the reception to the reply specified as described above. Calculate the time. For example, the data in the first line of FIG. 4 receives an e-mail at 9:05:15 on 01/01/2017 and replies to the e-mail at 11:30:27 on the same day. Is shown. On the other hand, the data in the first row of FIG. 2 shows that the meeting is scheduled from 9:00:00 to 11:00:00 on 01/01/2017. The reply status specifying unit 13 calculates the time obtained by subtracting the time in the time zone overlapping with the schedule of the meeting from the time from the reception to the reply. In this case, the deducted time is 30 minutes and 27 seconds from 11:00 to 11:30:27.

Further, as shown in FIG. 5, the e-mail is received at 22:00, the e-mail is replied to the e-mail at 10:00 the next day, and the user responds to the e-mail from 23:00 to 8:30. If you were asleep, the deducted time would be two and a half hours.

Further, as shown in FIG. 6, the e-mail was received at 10:00 and the e-mail was replied to the e-mail at 15:00 on the same day, from 11:00 to 12:00 and 13:00 to 13:00. If the terminal 20 is left unattended at 14:30, that is, the terminal 20 is not in the user's hand, the deducted time is two and a half hours.

Further, as shown in FIG. 7, an e-mail is received at 7:00 and a reply to the e-mail is sent at 11:00 on the same day, and the user enters the car from 8:00 to 9:30. If you were on board, the deducted time would be two and a half hours. If there is no time zone to be deducted between reception and reply, there is no need to deduct.

The reply status specifying unit 13 compares the deducted time with a preset threshold value (for example, 3 hours). When the deducted time is equal to or less than the threshold value, the reply status specifying unit 13 determines that the reply is made within the threshold time, that is, the reply is made within a certain time.

The reply status specifying unit 13 makes the above determination regarding reception within the two periods. One of the two periods (predetermined period 2) is a period for which the state of the user is to be determined, and is, for example, a predetermined day. The other period is a period to be compared with the period to be judged (predetermined period 1), and is, for example, a period retroactive from the above-mentioned predetermined period 1 by a preset time (for example, the past one month). .. As a result, it is possible to grasp the current (determination target period) and past user response tendencies.

The reply status specifying unit 13 calculates a procrastination score S, which is a score indicating the degree to which the user is procrastinating, based on the determination of reception in the above two periods. The procrastination score S is a score indicating the reply status of the user. The reply status specifying unit 13 calculates the response rate for each time zone of the user by the following formula for each time zone (for example, hourly time zone) of the day for the predetermined periods 1 and 2.
Response rate by time zone = number of replies / number of receptions in the time zone

The time zone is based on, for example, the reception time. For example, reception with a reception time of 0:30 is used to calculate the response rate for each time zone from 0:00:00 to 1:00:00. FIG. 8 shows a graph of the response rate by time zone in each time zone for each of the predetermined periods 1 and 2. The response rate for each time zone may be weighted according to the time so that the shorter the deducted time (time until reply), the larger the value.

The reply status specifying unit 13 compares the response rates for each of the two predetermined periods 1 and 2 for each time zone. The reply status specifying unit 13 aggregates the time zones in which the response rate for each time zone in the predetermined period 2 is lower than the response rate for each time zone in the predetermined period 1. The ratio of the total number of time zones to the number of all time zones is defined as the procrastination score S on that day (predetermined period 2).

For example, in the six time zones, the procrastination score S _01/01/ in 2017/01/01, where the response rate for each time zone of the predetermined period 2 is low,
S _01/01 = _6/24
Will be. The procrastination score S indicates that the higher the value, the greater the degree to which the user is procrastinating.

In any one of the predetermined periods 1 and 2, the time zone in which there is no reception and the response rate for each time zone cannot be calculated may be excluded from the calculation of the procrastination score S. The reply status specifying unit 13 may calculate the procrastination score S for a plurality of predetermined periods 2. For example, the reply status specifying unit 13 calculates the procrastination score S for each day. FIG. 9 shows a graph of the procrastination score S calculated for each day.

The reply status specifying unit 13 may calculate the procrastination score S based on the response rate for each day of the week. The reply status specifying unit 13 calculates the response rate for each time zone on the same day of the week as the predetermined period 2 in the predetermined period 1, and calculates the procrastination score S.

The reply status specifying unit 13 may calculate the procrastination score S for each tool used, and calculate the final procrastination score S from them. For example, the reply status specifying unit 13 calculates Procrastination score S _M in the _e-mail, telephone procrastination score S _T, and the application of Procrastination score S _A respectively, final earlier by the following equation from them Calculate the procrastination score S.
Procrastination score S = (w _M x _SM ) + (w _T x S _T ) x (w _A x S _A )
The above w _M , w _T , and w _A are values indicating weights for each score and are preset. The values of w _M , w _T , and w _A are determined by which tool's score is emphasized.

The reply status specifying unit 13 may not use all the receptions for the calculation of the procrastination score S, but may use only the receptions that are considered to require a reply for the calculation of the procrastination score S. For example, the e-mail received by the terminal 20 includes a large number of e-mails that do not require a reply. For example, it is not necessary to reply to well-known documents, e-mails related to conference communications and advertisements, and junk e-mails. Therefore, in order to appropriately estimate the degree of procrastination for the e-mail to be replied, the reply status specifying unit 13 may specify the e-mail to be replied. For example, the reply status specifying unit 13 targets only e-mails having a specific description in the title or body of each received e-mail included in the communication history. As a specific description, for example, a description requesting a reply such as "Please reply by X days" or "I would appreciate it if you could reply". As described above, the reply status specifying unit 13 may specify the reply status of the user based on the title or body of the received e-mail that is the reply target. Alternatively, the reply status specifying unit 13 may specify the e-mail to be replied from the received e-mail based on the sender such as the e-mail address. For example, only the e-mail received from the preset sender may be targeted, or the e-mail received from the preset sender may be excluded from the target. Further, the reply status specifying unit 13 may postpone only the reception in which the user actually replies and use it for calculating the score S. That is, the reply status specifying unit 13 may specify the reply status of the user based only on the reception.

The reply status specifying unit 13 may classify the reception into those related to business and those related to private as the type of reply target, and may calculate the procrastination score S for each classification. For example, in the case of e-mail, when two accounts, an account used for business and an account used for private use, can be used on the terminal 20, they are classified according to the received account. As for the telephone numbers, if two telephone numbers, a telephone number used for business and a telephone number used for private use, can be used in the terminal 20, they are classified according to the incoming telephone number. In addition, for the application, it is set in advance whether to use it for business or private use.

Further, the reply status specifying unit 13 starts from the time from reception to reply based on the above classification and the time zone during work and the time zone during private indicated by the information input from the user status detection unit 12. , The time may be calculated by subtracting the time in the time zone estimated that the reply is not possible. In the case of private reception, the reply status specifying unit 13 calculates the time obtained by subtracting the time during the business hours from the time from reception to reply. For example, as shown in FIG. 10 (a), a private e-mail is received at 10:30, and the e-mail is replied to the e-mail at 20:30 on the same day, from 9:30 to 18:00. If is during business hours, the deducted time will be two and a half hours.

In the case of reception related to business, the reply status specifying unit 13 calculates the time obtained by subtracting the time in the private time zone from the time from reception to reply. For example, as shown in FIG. 10 (b), a business e-mail is received at 20:30, and the e-mail is replied to the e-mail at 10:00 the next day, from 18:00 to the next. If 9:00 on the day is a private time zone, the deducted time will be one hour. The reply status specifying unit 13 calculates the procrastination score S based on the time subtracted in the same manner as described above.

The reply status specifying unit 13 outputs the calculated procrastination score S to the estimation unit 14. Although the procrastination score S described above is set on a daily basis (that is, the predetermined period 2 is one day), it may be on a weekly basis, a monthly basis, or the like.

The estimation unit 14 is a functional unit that estimates the user's state based on the procrastination score S calculated by the reply status specifying unit 13. The estimation unit 14 estimates the user's state based on the procrastination score S for each time zone. The estimation unit 14 may estimate the user's state based on the user's procrastination score S for each type of reply target. As described above, the estimation unit 14 estimates the mental state of the user. However, if it can be estimated from the procrastination score S, the user's state other than the mental state may be estimated.

For example, the estimation unit 14 estimates the user's state as follows. The estimation unit 14 inputs the procrastination score S from the reply status specifying unit 13. For example, when the procrastination score S is continuously increased, the estimation unit 14 estimates that the load is mentally high. Specifically, the estimation unit 14 continues to be in a state where the user is procrastinating things to a large extent when the procrastination score S exceeds the preset threshold value continuously for a preset number of days. It is presumed that the patient is mentally overloaded. In the example of the procrastination score S shown in FIG. 9, it is estimated that the tendency of procrastination is strong from the middle of the month to the end of the month, and the load is mentally high. The estimation unit 14 outputs information indicating the estimated state of the user to the output unit 15.

The output unit 15 is a functional unit that outputs information according to the estimation by the estimation unit 14. For example, the output unit 15 inputs information indicating an estimation result from the estimation unit 14 and transmits it to the user's terminal 20. This can be useful for the mental health care of the user. The information to be output is not limited to the information indicating the estimation result, and may be any information as long as it is the information according to the estimation by the estimation unit 14. Moreover, the output destination and the output mode may be any. The above is the function of the server 10 according to the present embodiment.

Subsequently, the process (operation method performed by the server 10) executed by the server 10 according to the present embodiment will be described with reference to the flowchart of FIG. In this process, first, the communication history acquisition unit 11 receives and acquires the communication history transmitted from the terminal 20 (S01). Subsequently, the user status detection unit 12 acquires status detection information (S02). Subsequently, the user status detection unit 12 detects the user status based on the status detection information (S03).

Subsequently, the reply status specifying unit 13 excludes (subtracts) the non-reply time indicated by the user's situation from the time from reception to reply indicated by the communication history (S04). Subsequently, the reply status specifying unit 13 calculates the response rate for each time zone based on the time after exclusion (S05). Subsequently, the reply status specifying unit 13 calculates the procrastination score S based on the response rate for each time zone (S06). Subsequently, the estimation unit 14 estimates the user's state from the procrastination score S (S07). Subsequently, the output unit 15 outputs the estimation result (S08). The above is the process executed by the server 10 according to the present embodiment.

As described above, in the present embodiment, the user's reply status is specified based on the user's situation that may affect the reply, and the user's state is estimated. For example, as described above, the reply status of the user is specified by subtracting the time when the user cannot reply. Therefore, the user's state is estimated in consideration of the user's situation. For example, a user is distinguished from a case where the reply is delayed as a result of the user procrastinating due to deterioration of the mental state and a case where the reply is unavoidably delayed due to the user's situation regardless of the mental state. State is estimated. As a result, the user's state can be estimated accurately.

Further, in the present embodiment, the state of the user can be estimated without monitoring the user with a camera, a microphone, or the like for a long period of time. Therefore, according to the present embodiment, it is possible to estimate without having to prepare those devices and without causing a privacy problem and a battery consumption problem when the devices are attached to the user. .. Further, since it is possible to estimate if the communication history of the user can be acquired, it is possible to estimate without limiting the user.

Further, as in the present embodiment, the detection of the user's situation may be performed by a method using the user's schedule as described above, a method using information indicating the behavior of the terminal 20, or the like.
