The model definition unit 16 defines a situation transition model and stores the defined situation transition model in the scratch pad 123b. Here, the “situation transition model” is a model that defines the transition order of the user's situation depending on the life cycle information representing the daily life cycle of the user and the position information representing the place where the user is present.
In addition, “life cycle information” refers to information representing a daily life cycle that is different for each user, such as the user's wake-up time, bedtime, start time, end time, wake-up time, and bedtime. The model definition unit 16 includes user-set time information indicating times such as wake-up time, bedtime, start time, and end time input by the user, and “wake-up time zone”, “sleep time”, and “wake-up time”. Life cycle information is defined by associating life cycle classification items such as “sleeping time”, “starting time”, and “working time”.

Further, the “situation” represents a situation or state where the user is placed. In the present embodiment, situations can be mainly classified into point situations (PS), line situations (LS), and special situations (SS).
The “point situation (PS)” is a situation that is estimated based on the life cycle information of the user and the area where the user is located, and is the starting point of the action. Point situations include getting up, starting work, starting work, ending work, returning home, going to bed, going out, and the like. A point situation automatically transitions to the associated line situation.

A “line situation (LS)” is a situation that connects two point situations, and there are during preparation, going to work, working, overtime, going home, going home, sleeping, going out, and the like.
A “special situation (SS)” is a situation that is neither a point situation nor a line situation, and in this embodiment, there is a situation called “being lost”. This situation is a situation when the current user situation is unknown, such as when starting for the first time or before acquiring the first position information.

FIG. 4 shows an example of the situation transition model. In the figure, situations such as “sleeping”, “going out”, “getting up”, “medium condition” indicate life cycle information such as “before bedtime”, “before worktime”, and “HA”, The state of transition according to areas such as “WA” and “EX” is conceptually shown. Note that “EX” in the figure refers to an undefined area (except area) other than the defined area.

In the table shown in the figure, the situation before the user transition, the area (HA, provisional HA, WA, provisional WA, EX), life cycle information (wake-up time zone, start time, work time, etc.), current Is associated with the situation.

  FIG. 6 shows an example of a general transition pattern of a situation on weekdays. The user's situation on weekdays generally transitions to “getting up” and “medium condition” in HA, and when the user moves from HA to EX, the situation further transitions to “commuting to work” and “commuting to work” When the user moves from EX to WA, the situation further shifts to “work start”, “working”, “overtime work start”, and “overtime work”, and when the user moves from WA to EX, the situation further “work end” When the user moves from EX to HA, the situation further transitions to “going home”, “at home”, “sleeping”, and “sleeping”.

  In FIG. 7, the example of the general transition pattern of the situation in a holiday is shown. The situation of a user on a holiday generally transitions to “getting up” and “at home” in the HA, and when the user moves from the HA to the EX, the situation further transitions to “outing” and “outing”. When EX moves from EX to HA, the situation further transitions to “return home”, “at home”, “sleeping”, and “sleeping”. As described above, since the situation transition patterns generally differ between weekdays and holidays, the model definition unit 16 defines two types of lifestyle models for weekdays and holidays, and associates them with weekday holidays. Remember.

The generation unit 2C includes a display information generation unit 26, a map information storage unit 23, a display control rule storage unit 24, and a position correction determination unit 25.
The map information storage unit 23 is a database provided in the hard disk, and stores image data for displaying a map.

  The display control rule storage unit 24 is a display control table provided in the hard disk, and stores display control rules. FIG. 12 shows an example of the display control table. As shown in the figure, the “user ID” and “the situation not to be displayed” are stored in the display control table. The data can be registered by user input from the mobile terminal 100. For example, in the display control table shown in FIG. 12, the user ID “001” is stored in association with “not getting up”, “mid-career”, “at home”, and “sleeping” as situations not to be displayed. Therefore, by performing display control using this display control table, it is possible to prevent the contents of the situation related to private about the user identified by the user ID “001” from being displayed.

  In the log information management table, the position correction determination unit 25 includes a plurality of pieces of position information (latitude and longitude) stored in association with the same situation and having different positions indicated by the position information. In this case, it is determined whether or not the difference in position is due to a GPS positioning error in the position information acquisition unit 13. For example, in the case where the same situation is estimated by the situation estimation unit 17 based on the fact that the user is in the same area, the position correction determination unit 25 is caused by a positioning error. It is determined that In addition, when the positions are close to each other or when the difference between the times corresponding to the respective positions is within a predetermined time, it may be determined that the difference in position is due to the positioning error.

The display information generation unit 26 includes a map information generation function 261 and a time series information generation function 262.
The map information generation function 261 displays the contents of the situation stored in the log management table in association with the latitude and longitude at the position on the map indicated by the latitude and longitude stored in the log information management table. Map information for displaying the user action history is generated. At this time, the map information generation function 261 generates map information by excluding “situations not to be displayed” stored in the display control table. FIG. 13A and FIG. 14A show an example of the user behavior history on the map displayed based on the map information generated by the map information generation function 261. FIG. 13A shows the log information of the user ID “001” stored in the log information management table shown in FIG. 11 and the display control of the user ID “001” stored in the display control table shown in FIG. It is a user's action history displayed based on a rule. 14A shows the log information of the user ID “002” stored in the log information management table shown in FIG. 11 and the display control of the user ID “002” stored in the display control table shown in FIG. It is a user's action history displayed based on a rule.

  In the display control table shown in FIG. 12, a situation “Wake up, dressed, staying at home, sleeping” associated with the user ID “001” is stored. For this reason, in the log information management table shown in FIG. 11, “wake-up”, “mid-career”, “at home”, and “sleeping” are registered as user situations identified by the user ID “001”. In spite of this, in FIG. 13A, these situations are not displayed, but only “commuting” corresponding to work, “work” corresponding to work, and “return” corresponding to returning home. It is displayed.

  In addition, in the display control table illustrated in FIG. 12, a situation “none” that is not displayed is stored in association with the user ID “002”. For this reason, in the log information management table shown in FIG. 11, the situations “Wake up”, “At home”, “Out of office”, and “Being sleeping” stored in association with the user ID “002” are all displayed. In FIG. 14A, “sleeping”, “at home”, and “going out” corresponding to all these situations are displayed.

  The time series information generation function 262 generates time series information for displaying the contents of the user situation in time series. At this time, like the map information generation function 261, the time series information generation function 262 excludes “situations not to be displayed” stored in the display control table and generates time series information. FIG. 13B and FIG. 14B show an example of a time table displayed based on the time series information generated by the time series information generation function 262. FIG. 13B shows the log information of the user ID “001” stored in the log information management table shown in FIG. 11 and the display control of the user ID “001” stored in the display control table shown in FIG. It is a time table displayed based on a rule. 14B shows the log information of the user ID “002” stored in the log information management table shown in FIG. 11 and the display control of the user ID “002” stored in the display control table shown in FIG. It is a time table displayed based on a rule. In each time table shown in FIGS. 13B and 14B, the contents of the situation to be displayed are displayed in the order of time recorded in the log information management table. Further, in each time table, a time display in increments of 6 hours is made on the right side so that the approximate time stored in the log information management table in association with each situation can be known.

13 and 14 show display examples for displaying both the user action history on the map and the time table. However, the display method is not limited to this. For example, only the user action history on the map is displayed. It may be displayed, or only the time table may be displayed.
In addition, the display information generation unit 26 differs from the position correction determination unit 25 in the position information indicated by each position information among a plurality of pieces of position information associated with the same situation stored in the log information management table. Is present, and it is determined that the difference in position is due to a positioning error, one correction position information for the plurality of different position information is generated, and the same as each position indicated by each of the plurality of position information Instead of displaying the contents of the situation, map information for displaying the contents of the same situation at one position indicated by the corrected position information is generated.

For example, if the same situation is estimated based on the fact that the user is in the same area, and it is determined that the difference in position is due to a positioning error, display information generation is performed. The unit 26 uses the position information indicating the center of the same area as the corrected position information.
FIG. 15A shows a display example when position correction is not performed. As shown in FIG. 15A, when the “at home” situations are displayed in a circle in the HA, the “at home” situations are estimated by the user being at the HA. Therefore, the display information generation unit 26 uses the position information indicating the center of the HA as the corrected position information. With this correction, as shown in FIG. 15B, the “at home” situation can be displayed collectively at the center position of the HA.

(Action history display program)
As described above, the program (corresponding to the “behavior history display program”) stored in the storage device 202 of the server device 200 is transferred to the server device (corresponding to “computer”) 200 to the user situation and the user position. The information and time information are associated with each other and the log information storage unit 22 that sequentially stores the information as log information, and the position on the map indicated by the position information stored in the log information storage unit 22 is associated with the position information. It is a program for functioning as a display information generation unit 26 that generates map information for displaying a user action history that displays the contents of the situation stored in the log information storage unit 22.

Since it transmits to the client apparatus 300, the client apparatus 300 can display a user's 1 day action history on a map based on the said map information. In this way, not only the location information on which the user stayed can be displayed on the map, but also the situation of the user at that location can be displayed, so that the user can look back on the day in more detail. Become.

  Furthermore, since the display information generation unit 26 further generates time series information for displaying the contents of the user's situation in time series, the client device 300 can display a time table based on the time series information. . By displaying the time table together with the action history on the map, it is possible to visually recognize the detailed action history of the user for one day.

  Further, among the plurality of pieces of position information associated with the same situation stored in the log information storage unit 22 by the position correction determination unit 25, there are pieces of information in which the positions indicated by the respective position information are different. When it is determined that the difference is due to the positioning error, the display information generation unit 26 can correct the position information difference due to the positioning error and display the contents of the situation at one corrected position. Therefore, it is possible to display the user's action history accurately and easily.

  The display control rule storage unit 24 stores situations that are not to be displayed, and the display information generation unit 26 stores map information and time-series information except for situations that are not to be displayed stored in the display control rule storage unit 24. For example, privacy-related situations such as “at home” and “sleeping” are stored in the display control rule storage unit 24 as non-display objects so that the user's privacy information is hidden. Therefore, the present invention can be used for public purposes such as attendance management for outside sales, creation of business reports, business diaries, and the like.

  In addition, the function with which each apparatus which comprises the action log | history display system which concerns on embodiment mentioned above is provided is only an example, and each function may be provided in any apparatus of the portable terminal 100, the server apparatus 200, and the client apparatus 300. . For example, only the server device 200 may be provided with each function, or another device other than the mobile terminal 100, the server device 200, and the client device 300 may be provided.

In addition, the information displayed on the map is not limited to the situation, and a time corresponding to each situation may be displayed, or an advertisement corresponding to the situation may be displayed.
Moreover, you may display a user's condition with a user's situation. The user condition is a state of mind and body of the user, and can be estimated from a condition index calculated based on log information stored in the log information storage unit 22. The condition index includes, for example, “sleep index”, “labor index”, “energy index”, “mannerin index”, “withdrawal index”, “tension index”, and the like.

  The “sleep index” is an index that serves as an index as to whether or not the user has enough sleep. For example, the average value of the user's past sleep time based on the estimated wake-up time and the estimated bedtime stored in the log information storage unit 22 (that is, the time from the estimated bedtime to the estimated wake-up time) is the latest sleep of the user. When the time is longer than the average value of the past sleep time, a value indicating that the user's sleep is more sufficient as the “sleep index” is calculated, and the user's latest sleep time is the average value of the past sleep time In the case where it is shorter, a value indicating that the user's sleep is insufficient is calculated as the “sleep index”.

  The “labor index” is an index serving as an index of whether or not the user is working too much. For example, the latest working hours of the user calculated based on the date and time associated with the situations such as “working”, “overtime”, “working start”, “working end” in the log information storage unit 22 When the user's past working time is longer than the average value, the value indicating that the user's working time is longer is calculated as the “working index”, and the user's latest working time is calculated. Is shorter than the average value, a value representing that the user's working time is shorter is calculated as the “labor index”.

“Energy index” is an index indicating the degree of the user's energy. For example, the “energy index” is calculated by adding the “sleep index” and the “labor index”.
The “Mannery index” is an index serving as an index as to whether or not there is a change in the daily life pattern of the user. For example, the user's daily home return time calculated based on the date and time stored in the log information storage unit 22 in association with situations such as “work end” and “return home” (that is, home return from work end) If the difference between the time until the start of work (that is, the time from the start of work to the start of work) is all (or may be a part) within a predetermined time (for example, within 30 minutes), A value indicating that the change in the user's life pattern is smaller is calculated as an “index”, and the difference between the time of going home and the time of going to work every day exceeds one predetermined time (or may be all). If it is, a value indicating that the change in the life pattern of the user is larger is calculated as the “manneriness index”.

  The “withdrawal index” is an index indicating a tendency of withdrawal in which the user avoids participation in society. For example, based on log information and area definition information, the user's situation on holiday is “at home” and the “energy index” indicates that the degree of user's lack of energy is relatively high (for example, “ If it is determined that the spirit index is 0 or less) and the user is staying in the area where the user lives (for example, HA or temporary HA in this embodiment) for a predetermined time or more (for example, 6 hours or more) As the “index”, a value indicating that the tendency of withdrawal of the user is higher is calculated.

In addition, when the user's withdrawal tendency is higher, when it is determined that the user has moved out of the HA and the temporary HA based on the user history log, or the user's situation is “out of office” In such a case, a value indicating that the tendency of the withdrawal of the user is lower is calculated as the “withdrawal index”.
The “tension index” is an index indicating whether the user's mood is uplifting or sinking. For example, the “tension index” is calculated based on the content of the user's response to the question.

  Since the user's behavior history can be automatically displayed, the present invention can be used for diaries, attendance management for outside sales, creation of work reports, work diaries, family location management, and the like.
