Description

  The present invention relates to a schedule management apparatus, method, and program for supporting schedule management of a user by cooperation with the user location information management.

  2. Description of the Related Art In recent years, research and development of a system that provides services using position information acquired by a GPS (Global Positioning System) carried by a user has been promoted. As an example of such a system, a system that displays building information around the acquired current location or a system that performs navigation by inputting a destination is common.

On the other hand, the number of users who use an electronic scheduler has increased in recent years, regardless of whether they are online or offline.
However, for technologies that support schedule management by integrating the user's real-world location information acquired by sensors such as GPS and schedule information, which is information on the user's cyberspace, The situation has not yet been provided.

  As a conventional technique related to user position information, a technique for performing position estimation based on a plurality of pieces of position information having different accuracy and measurement time is known (for example, see Patent Document 1 below). This Patent Document 1 describes that a scheduler manages a location where a moving object exists and calculates a moving speed from that location.

  However, the technique of Patent Document 1 does not use information indicating the location of the moving object for the purpose of supporting the schedule management of the user, although the main body that manages the location of the moving object is the scheduler. . In other words, some information processing is not performed using information indicating the location of the moving object and schedule information input in advance to the scheduler.

  Therefore, the technique described in Patent Document 1 does not link the user location information management and the scheduler for the purpose of supporting the user schedule management.

In the present embodiment, the location information acquisition system 100 periodically acquires the location information of the user in the real world as described above from the GPS mobile phone 200.
As for schedule information, which is information on the cyber space of the user, the scheduler system 101 stores and holds information registered by the user using the GPS mobile phone 200 or another computer.

  Information that represents the schedule includes the location (the “destination” when movement is required), the estimated arrival time at the destination, the nearest station at the destination, the estimated arrival time at the nearest station at the destination, the subject, and the contents of the schedule Etc. The scheduler system 101 periodically monitors the user's schedule information, and when a change such as a new creation, correction, or deletion of a schedule occurs, a file representing the schedule information is generated and the position information acquisition system 100 receives it. Send. In the present embodiment, for example, a file in iCalender format, which is one of general-purpose formats for representing schedule information, is used (hereinafter referred to as “iCalender file”).

  The present embodiment is characterized in that the location information in the real world of the user acquired by a sensor such as GPS and the schedule information that is information on the user's cyberspace are integrated. In addition to the user's schedule, the information has been extended so that information such as the user's place of stay and transportation means can be described. The position information acquisition system 100 describes information such as a user's place of stay and moving means periodically acquired from the GPS-equipped mobile phone 200 in an iCalendar file and transmits it to the scheduler system 101 as needed.

  The location information acquisition system 100 obtains the nearest station A in the current location when using transportation by searching a database (not shown) or the like based on the current location information of the user acquired from the GPS mobile phone 200. Further, the nearest station B of the destination and the scheduled arrival time at the nearest station B are obtained from the schedule information, and these pieces of information necessary for the route search are transmitted to the route search system 102.

  The route search system 102 performs a route search based on the information received from the position information acquisition system 100, calculates a departure time t1 and a travel time p (N), and returns the calculated time to the position information acquisition system 100. Here, the “departure time” represents the time at which the user should depart in time for the schedule in view of the user's current location.

The position information acquisition system 100 performs notification of departure time and control of an alert to the GPS mobile phone 200 based on the information of the departure time t1 and the travel time p (N) received from the route search system 102.
FIG. 2 is a block diagram showing an internal configuration of the schedule management system shown in FIG.

  The position information acquisition system 100 includes the alert control unit 1 that performs departure time notification and alert control for the GPS mobile phone 200 as described above. In addition, the position information acquisition system 100 includes the schedule information processing unit 2 that generates an iCarender file in which a user's place of stay and moving means are described as described above.

As described above, the scheduler system 101 includes the schedule information processing unit 3 that generates an iCarender file representing user schedule information. The route search system 102 includes a calculation unit 4 that calculates the above-described departure time t1 and travel time p (N).
(Departure time notification)
The position information acquisition system 100 acquires schedule information including the user's destination and scheduled arrival time from the scheduler system 101 and acquires position information representing the user's current position at the current time from the GPS mobile phone 200. Here, the alert control unit 1 of the location information acquisition system 100 acquires from the route search system 102 the departure time to depart from the current location for the above destination, scheduled arrival time, location information indicating the current location, and the current time. This can be notified to the GPS mobile phone 200.
(Alert)
Further, the alert control unit 1 acquires the travel time from the current location of the user to the destination at different current times from the route search system 102. Then, the first travel time acquired at the first time by the route search system 102 is compared with the second travel time acquired at the second time from the route search system 102, and the second travel time is compared. If the time is greater than or equal to the first travel time and the difference between the departure time and the current time is greater than or equal to a predetermined set value, an alert is transmitted to the user.
(Alert control)
Furthermore, in this embodiment, the alert control unit 1 moves the user toward the destination if the second movement time is shorter than the first movement time, as will be described in detail below. In order to prevent the excessive alert from being transmitted to the user, it is prohibited to transmit the alert.

FIG. 3 is a diagram illustrating a processing flow in the schedule management system of the embodiment.
The scheduler system 101 periodically monitors the input schedule information, and if there is a change, exports it to an iCalender file that is a standard calendar format (step S1). In the schedule information, it is assumed that the nearest station B of the destination to which the user goes on a business trip or the like and the scheduled arrival time at the nearest station B of the destination are input.

  The location information acquisition system 100 imports the iCalender file exported by the scheduler system 101 (step S2). In parallel with this, the position information acquisition system 100 periodically acquires position information from the GPS mobile phone 200 carried by the user.

  Next, the location information acquisition system 100 searches the imported iCalender file for the schedule closest to the current time, and acquires the destination, the nearest station B at the destination, and the estimated arrival time at the nearest station B ( Step S3). Next, the position information acquisition system 100 acquires the nearest station A of the current location from a database or the like from the periodically acquired GPS position information (step S4). Then, the acquired estimated arrival times at the nearest station A of the current location, the nearest station B of the destination, and the nearest station B are transmitted to the route search system 102 (step S5).

  Next, the route search system 102 receives, as inputs, the nearest station A at the current location, the nearest station B at the destination, and the estimated arrival time at the nearest station B received from the location information acquisition system 100. The departure time t1 and the travel time p (N) in time for the scheduled arrival time are calculated and transmitted to the position information acquisition system 100. The travel time p (N) is temporarily stored in the storage means such as a memory as the travel time p (N-1) so that it can be compared with the travel time p (N) calculated next time.

Next, the position information acquisition system 100 compares the travel time p (N) received from the route search system 102 with the travel time p (N-1) acquired last time (before one sampling) (step S7). .
If p (N) ≧ p (N−1), the difference between the received departure time t1 and the current time t2 is obtained (step S8). If the difference value is less than or equal to the set value n, an alert mail is transmitted to the GPS mobile phone 200 (step S9). In addition, after step S9, you may repeat operation | movement of step S4-step S8.

On the other hand, if p (N) <p (N−1) in step S7, the travel time to the destination has decreased, so the user determines that he is heading to the destination, and the alert mail is Return to step S4 without transmitting.
As described above, supporting the user's schedule management based on the position information in the real world of the user acquired by a sensor such as GPS and the schedule information that is information on the user's cyberspace Can do. In particular, according to the present embodiment, it is determined that the user is moving toward the destination, and in that case, in order to prevent an excessive alert from being transmitted to the user, Transmission can be prohibited. Therefore, the convenience of the schedule management system can be improved.

  The location information acquisition system 100 identifies the user's transportation means and staying location information from the periodically acquired location information and current time of the user, creates and corrects an iCalender file describing them, and creates a scheduler. The file is stored in a location where the system 101 can read it. The user's moving means is obtained by an algorithm that can be classified into three types of walking, car, and train from the average speed calculated from the position information and time information.

The user's moving means and staying place information are in the same general-purpose format as the schedule input by the user or the like, and are described in the LOCATION tag of the VEVENT tag, DTSTART, DTEND tag, etc. in the iCalender file.
As shown in FIG. 4, the scheduler system 101 reads this, and displays the user's actual moving means and stay location information 301 together with the original schedule information 302 on the scheduler screen 300, so that the user himself / herself and the third party are displayed. It is possible to compare and grasp the schedule described in the scheduler and the actual user behavior. Therefore, there is an advantage that schedule management can be performed while grasping actual user behavior.
