Description

  The present invention relates to a document information recording apparatus, a document information recording method, a document information recording program, and a document information recording system for recording information for creating a document.

  A technique is known in which a position of a user is specified by a GPS module and movement history information (GPS log) in which the position is associated with time is recorded (see Patent Document 1). In recent years, GPS modules have been installed in general mobile phones and the like, and it has reached a situation where movement history information for many users can be recorded on mobile phones and the like.

JP 11-183594 A

However, since the movement history information is information with which the user's behavior can be estimated, it is not desirable to transmit / receive movement history information or information extracted from the movement history information against the user's intention. In particular, when a document is created based on movement history information about a time zone in which the user wants to keep his / her action secret, the user's privacy is greatly impaired.
SUMMARY An advantage of some aspects of the invention is that it provides a technique for preventing information in a time zone unintended by a user from being reflected in document information.

  In order to achieve the above object, in the document information recording apparatus of the present invention, movement history information acquisition means acquires movement history information indicating a plurality of times and positions corresponding to the times. The period specifying unit specifies a target period for which a document is to be created. The target period information extraction unit extracts target period information indicating the time belonging to the target period and the position corresponding to the time from the movement history information without extracting information related to a period other than the target period from the movement history information. Then, the document information recording means extracts document information for document creation from the target period information and records it. With this configuration, document information for document creation can be extracted from only the target period information related to the target period, and information related to a period other than the target period can be prevented from being reflected in the document information. That is, it is possible to prevent information on a time zone not intended by the user from being recorded as document information.

Further, the period specifying unit may be configured such that the position indicated by the movement history information moves from the predetermined first position to the second position until the time indicated by the movement history information moves from the second position to the first position. This period may be specified as the target period. That is, the period from the time corresponding to the forward path from the first position to the second position to the time corresponding to the return path returning from the second position to the first position can be set as the target period.
For example, by setting the first position as the user's home position and the second position as the user's work location, the period from when he / she leaves the workplace to the time of leaving the office can be the target period. Document information suitable for reporting earlier can be recorded. The work place includes a business trip destination and the second position is not limited to a single position. In addition, the time of movement from the first position to the second position and the time of movement from the second position to the first position may be a movement start time or an end time. However, it may be an intermediate time between them.

The period specifying means may specify a period other than the period in which the position indicated by the movement history information is within a predetermined range as the first period. Thereby, it is possible to prevent the document information from reflecting the period in which the position indicated by the movement history information exists within the predetermined range, that is, the user's behavior within the predetermined range.
For example, the predetermined range may be a range within a predetermined distance from the position of the user's home. Thereby, it is possible to prevent the user's private behavior in the living area centering on the position of the home from being reflected in the document information.

  Note that the function of each means described in the claims is realized by a hardware resource whose function is specified by the configuration itself, a hardware resource whose function is specified by a program, or a combination thereof. The functions of these means are not limited to those realized by hardware resources that are physically independent of each other. Furthermore, the present invention can also be established as a method, a computer program for causing the server and printer to realize the functions described above, and a recording medium for the program. Of course, the recording medium for the computer program may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium developed in the future.

The map information 12a is information indicating the names of various facilities and the positions (latitude / longitude) of the facilities. Further, the map information 12a indicates the position of the user's home and the position of the user's work location. The movement history information 12b is information indicating a plurality of past times and a position (latitude / longitude) where the mobile terminal 10 is present at the time. The target period information 12c is information obtained by extracting the time belonging to the target period and the position corresponding to the time from the movement history information 12b. The document information 12d is information used by the server 20 to create a business trip report as a document.

  The GPS receiver 13 receives a GPS signal from a GPS satellite and outputs the GPS signal to the control unit 11. The communication unit 15 includes a circuit for causing the server 20 and the mobile terminal 10 to communicate by wireless communication or wired communication. The UI unit 14 includes an output unit that outputs information so that the user can recognize, and an input unit that receives an input operation from the user. The UI unit 14 of the present embodiment includes a touch panel display that serves as both an output unit and an input unit. The UI unit 14 displays an image on the touch panel display based on the display signal output from the control unit 11, generates an operation signal based on the contact state of the finger with respect to the touch panel display, and outputs the operation signal to the control unit 11.

  The document information input program P1 includes a movement history information acquisition unit P1a, a period specifying unit P1b, a target period information extraction unit P1c, and a document information recording unit P1d. In the present embodiment, the document information input program P1 is executed for the purpose of creating a business trip report as a document. The movement history information acquisition unit P1a is a module that causes the control unit 11 to execute a function of acquiring movement history information 12b that indicates positions in association with each other at a plurality of times. That is, by the function of the movement history information acquisition unit P1a, the control unit 11 specifies the position where the mobile terminal 10 exists based on the GPS signal output from the GPS receiver 13, and associates the position with the current time. Is stored in the recording medium 12 as movement history information 12b. With the function of the movement history information acquisition unit P1a, the control unit 11 specifies the current time and position every predetermined time period (for example, 1 minute period), and accumulates these in the movement history information 12b.

  The period specifying unit P1b is a module that causes the control unit 11 to execute a function of specifying a target period for which a document is to be created. In the present embodiment, the function of the designation information receiving unit P1b allows the control unit 11 to move the position indicated by the movement history information 12b from the user's home position (first position) to the work location (second position) ( The period from the arrival time) to the time (departure time) when the position indicated by the movement history information 12b moves from the user's work location (second position) to the home position (first position) is specified as the target period. As a result, the working period from when the user leaves the office to when he leaves the office can be the target period.

  The target period information extraction unit P1c is a module that causes the control unit 11 to execute a function of extracting the target period information 12c indicating the time belonging to the target period and the position corresponding to the time from the movement history information 12b. In the present embodiment, the function of the target period information extraction unit P1c causes the control unit 11 to extract information (time and position) belonging to the target period from the movement history information 12b, thereby corresponding to the time belonging to the target period and the time. The target period information 12c indicating the position to be acquired is acquired.

  The document information recording unit P1d is a module that causes the control unit 11 to execute a function of extracting document information 12d for creating a document from the target period information 12c and recording the document information 12d on the recording medium 12. With the function of the document information recording unit P1d, the control unit 11 extracts a time when the position change pattern indicated by the target period information 12c becomes a predetermined pattern as an extraction time. In the present embodiment, based on the change pattern of the position indicated by the target period information 12c, the time when the user carrying the mobile terminal 10 can be estimated to have changed the transportation means, and the user stays at a certain position for a long period of time. Period (start time to end time) is extracted as the extraction time. Further, the control unit 11 extracts the position associated with the extraction time in the target period information 12c as the extraction position by the function of the document information recording unit P1d, and the facility existing at the position closest to the extraction position is the map information 12a. As a transit facility. When the extraction time and the transit facility can be extracted as described above, the document information 12d indicating these in association with each other is recorded on the recording medium 12 and transmitted to the server 20.

(1-2) Server configuration:
The server 20 includes a control unit 21, a recording medium 22, and a communication unit 23. The control unit 21 includes a CPU, a ROM, a RAM, and the like, and executes the document creation program P2 based on program data recorded in the ROM or the recording medium 22. The recording medium 22 records transportation facility information 22a and document information 22b. The transportation facility information 22a is a database that records transportation timetables and transportation expenses. The document information 22 b is information obtained by recording the document information 12 d received from the mobile terminal 10 on the recording medium 22. The communication unit 23 includes a circuit for communicating the server 20 and the mobile terminal 10 by wireless communication or wired communication.

  The document creation program P2 is a program that receives the document information 12d and causes the control unit 21 to execute a function of creating a document based on the document information 12d. That is, the control unit 21 uses the function of the document creation program P2 when the transit facility indicated by the document information 22b (document information 12d) includes a plurality of transportation facilities (airport, port, station, bus stop, parking lot, interchange). Refers to the transportation information 22a and specifies the transportation cost between transportation facilities. And the control part 21 produces the business trip report which shows the said transportation expense, while showing a transit facility, and specifying a transportation expense.

(1-3) Document creation processing:
FIG. 2A is a flowchart of processing executed by the mobile terminal 10 in the document creation processing. In step S <b> 105 of FIG. 2A, the control unit 11 of the mobile terminal 10 acquires the movement history information 12 b from the recording medium 12. In the present embodiment, the movement history information 12b is recorded for each date. The control unit 11 receives an input of a business trip date from the user via the UI unit 14 and acquires movement history information 12b regarding the business trip date. In step S110, the control unit 11 starts from the time (arrival time) when the position indicated by the movement history information 12b moves from the position of the user's home to the work place, and the position indicated by the movement history information 12b changes from the user's work place to the home position. The period up to the time of moving to the position (departure time) is specified as the target period.

  FIG. 3A is a schematic diagram showing a locus of a position indicated by the movement history information 12b for a business trip date, and FIG. 3B is a table showing events E1 to E14 occurring on the business trip date in time series. In FIG. 3A, the locus of the position in the target period is indicated by a solid line, and the locus of the position outside the target period is indicated by a broken line. As shown in FIG. 3A, the position indicated by the movement history information 12b remains at the position of the home A until the user carrying the mobile terminal 10 leaves the home A. In this embodiment, the position of the user's home A and the position of the work place are registered in advance in the map information 12a, and the positions of the two user's work places (offices D and F) are registered in the map information 12a. Has been. Note that the user is based in the business office D, and the business in the business office F is treated as a business trip.

  First, the control unit 11 specifies the time when the distance from the position of the home A first exceeds a predetermined distance (for example, 100 m) based on the locus of the position indicated by the movement history information 12b. The time that is first traced and within a predetermined distance (for example, 100 m) from the position of the work place is set as the start of the target period. In the example of FIGS. 3A and 3B, the start of the target period is specified as the time (8:25) of the event E4 that first arrived at the office D as the work place. Moreover, the control part 11 specifies the time which was finally a predetermined distance (for example, 100 m) from the position of the home A based on the locus | trajectory of the position which the movement history information 12b shows, and the late | slow order of the time from the said time. The time at which the trajectory is traced and is finally within a predetermined distance (for example, 100 m) from the position of the work place is set as the end of the target period. In the example of FIGS. 3A and 3B, the end of the target period is specified as the time (17:05) of the event E10 that finally leaves the office F as the work place. That is, the target period is a period corresponding to the events E4 to E10.

  When the start and end of the target period can be identified as described above, in step S115, the control unit 11 does not extract information related to a period other than the target period from the movement history information 12b, and the target period from the movement history information 12b. The target period information 12c indicating the time belonging to and the position corresponding to the time is extracted. That is, information indicating the time and position corresponding to the locus indicated by the solid line in FIG. 3A is extracted as the target period information 12c. In step S120, the control unit 11 extracts the extraction time from the target period information 12c.

  FIG. 4 is a graph showing the moving speed of the position indicated by the target period information 12c in the examples of FIGS. 3A and 3B. The moving speed means the amount of change per unit time of the position indicated by the target period information 12c. In the present embodiment, the control unit 11 extracts, as an extraction time, a time when the position (speed) change pattern indicated by the target period information 12c corresponds to the transfer pattern PT1 and the stop pattern PT2. Of course, since the target period information 12c indicates the time belonging to the target period and the position corresponding to the time, the time of the period other than the target period is not extracted as the extraction time.

  The transfer pattern PT1 is a pattern in which a difference in average speed between a first period p1 and a second period p2 (for example, every 5 minutes) that are temporally continuous is equal to or greater than a predetermined speed (for example, 10 km / hour). The time when the average speed is increased or decreased by a predetermined speed or more from the first period p1 to the second period p2 is the time when the user carrying the mobile terminal 10 changes from one transportation means (including walking) to another transportation means. Can be estimated. For example, while changing the time at the boundary between the first period p1 and the second period p2, the control unit 11 calculates the absolute value of the difference between the average speed in the first period p1 and the average speed in the second period p2 for each time. calculate. Then, the control unit 11 sets a time when the absolute value of the difference is larger than the predetermined speed and becomes a maximum value as the extraction time. As shown in FIG. 4, the absolute value of the difference in average speed is greater than or equal to a predetermined speed in the first period p1 until the station C is reached on foot and in the second period p2 after the train departs at the station C. In addition, the time becomes the maximum value, and the time at the boundary between the first period p1 and the second period p2 (event E6: 10: 50), that is, the departure time of the train boarded at the station C is specified as the extraction time. Similarly, in the first period p1 until the train stops at the station E and the second period p2 from the station E to the office E on foot, the absolute value of the difference in average speed is equal to or greater than a predetermined speed, and The maximum value is obtained, and the time at the boundary between the first period p1 and the second period p2 (event E7: 11: 25), that is, the stop time of the train that has got off at the station E is specified as the extraction time.

  On the other hand, the stop pattern PT2 is a pattern in which the time at which the speed becomes a predetermined speed (for example, 0.1 km / hour) or less continues for a predetermined period (for example, 10 minutes) or more. When the time at which the speed falls below the predetermined speed continues for a predetermined period or longer, the user carrying the mobile terminal 10 stays in the same position, for example, attending a meeting or desk work in the office It can be estimated. The control unit 11 specifies the stop pattern PT2 including at least a part of any time within a predetermined period from the specified time in the target period information 12c. A period (start time to end time) corresponding to the stop pattern PT2 is set as the extraction time. As shown in FIG. 4, the change pattern of the position (speed) in the period p3 participating in the conference at the establishment F corresponds to the stop pattern PT2, and the period p3 (event E9: start time (12:30)) To ending time (16:30) are taken as extraction times.

  When the extraction time can be extracted as described above, in step S125, the control unit 11 extracts a position associated with the extraction time in the target period information 12c as an extraction position. In the case of corresponding to the stop pattern PT2, the start time and the end time of the period corresponding to the stop pattern PT2 are specified as the extraction time, but the position corresponding to any of these may be set as the extraction position. This is because the position indicated by the target period information 12c hardly moves during the period corresponding to the stop pattern PT2. Furthermore, in step S130, the control unit 11 specifies a facility existing at the closest position from the extraction position by referring to the map information 12a, and sets the facility as a transit facility. As described above, in the example of FIGS. 3A and 3B, 10:50, 11:25, and 12:30 to 16:30 corresponding to the events E6, E7, and E9 are set as extraction times. , Station E and establishment F are identified as transit facilities. The control unit 11 records the document information 12d indicating the extraction time and the transit facility in association with each other in Step 135 in the recording medium 12, and transmits the document information 12d to the server 20 in Step 140.

  The document information 12d transmitted to the server 20 by the above processing is information reflecting the position of the user only in the target period from when the user enters the office D until he leaves the office F. The target period It is not information that reflects the user's position in other periods. Therefore, the user's privacy is not impaired by creating the business trip report based on the document information 12d. In the example of FIGS. 3A and 3B, it is possible to prevent the user from eating at the restaurant G at the event E13 (17:50 to 18:45) from being described in the business trip report.

  FIG. 2B is a flowchart of processing executed by the server 20 in the document creation processing. In step S205 of FIG. 2B, the control unit 21 of the server 20 receives the document information 12d in which the transit facility is associated with the extraction time from the server 20, and records it as the document information 22b on the recording medium 22. In step S210, the control unit 21 extracts a pair of transit facilities whose extraction times are continuous among the transit facilities indicated by the document information 22b and both are transit facilities. 3A and 3B, a pair of station C and station E is extracted. In step 215, the control unit 21 searches for public transportation routes connecting the pairs of transportation facilities whose extraction times are continuous and their transportation costs with reference to the transportation information 22a by a known route search method. In step S220, the control unit 21 prints a business trip report that describes the transit facility and the extraction time in association with each other and also describes the transportation cost between the transit facility, for example, by a printer.

  FIG. 5 is a diagram showing an example of a business trip report printed in the case of FIGS. 3A and 3B. As shown in FIG. 5, in the business trip report, transit facilities and extraction times are described in association with each other for events E6, E7, and E9. In addition, a settlement column is provided in the business trip report, and the transportation expenses of the trains used at the stations C to E are described in the settlement column.

(2) Other embodiments:
In the present invention, it suffices if the target period for document creation can be specified, and various methods can be adopted as a method for specifying the target section. For example, in the embodiment, the target period may be from the departure time from the home A to the work place to the arrival time at which the work A arrives at the home A. Furthermore, a period excluding a period in which the position indicated by the movement history information 12b is within a predetermined distance from the position of the user's home may be specified as the target period. Thereby, it is possible to prevent the user's private behavior within the living area centered on the position of the home from being reflected in the document information 12d. For example, as indicated by the alternate long and short dash line in FIG. 3A, a period in which the position indicated by the movement history information 12b exists within a range centered on the position of the home A and having the radius of the predetermined distance R may be excluded from the target period. The predetermined distance R may be determined based on, for example, a distance in a general living area, or a predetermined ratio (<1) to the distance between the position of the home A and the offices D and F that are work locations. May be determined by multiplying by

  Furthermore, when working hours (starting time to closing time) are set, the working hours may be set as the target period. In the embodiment, the business trip report is created as a document, but a document other than the business trip report may be created based on the movement history information 12b. For example, a travel report of an individual trip may be created based on the movement history information 12b, or a document reporting a meal at the restaurant G in the examples of FIGS. 3A and 3B may be created. When creating a document in which private matters are described in this way, the period excluding the target period in the embodiment may be handled as the target period. In this case, it is possible to prevent the user's behavior during the working period from being reflected in these documents. Therefore, even when the document information 12d for creating a document describing private matters is uploaded to a WEB server or the like, it is possible to prevent leakage of confidential information of the user's work place. Note that the document created based on the document information 12d may not be printed. For example, WEB page data for uploading to the WEB server may be created based on the document information 12d.

  In the embodiment, the document creation process is executed in the mobile terminal 10 and the server 20, but the document creation process may be completed in the mobile terminal 10, as a matter of course. Further, the server 20 may acquire the target period information 12c from the mobile terminal 10, and the server 20 may execute the subsequent processing. Further, a part of the document creation process may be executed in a client PC other than the mobile terminal 10 and the server 20. That is, after the user returns from the business trip, the target period information 12c may be transferred from the mobile terminal 10 to the client PC, and the document creation process may be executed between the client PC and the server 20.
