Description

  The present invention relates to a mobile terminal device.

  Conventionally, as a walking navigation technique for searching for a route to a destination using a mobile terminal device during walking, a standard walking speed of the user is obtained from a history of the walking speed of the user measured in the past, and based on the obtained walking speed In some cases, the required time to the destination is predicted (see Patent Document 1).

JP 2008-116320 A

  Here, assuming that walking navigation is performed using a portable terminal device in a sightseeing spot, it takes time for sightseeing in the sightseeing spot, so the walking speed becomes slower than the normal walking speed. For this reason, when the required time is obtained from the standard walking speed of the user as in the above-described conventional technology, the required time shorter than the actual time is calculated in the sightseeing spot. For this reason, for example, when it is assumed that the time to return to the meeting place is determined by a bus tour or the like and the user is notified of the alarm in consideration of the required time, the alarm is notified based on the required time shorter than the actual time. Therefore, there is a possibility that the user will be late for the set time.

  On the other hand, for users who want to spend as much time as possible for sightseeing at a point far from the meeting place and want to return to the meeting place quickly from that point, walking for sightseeing spots If the alarm notification is made based on the required time determined from the speed, there is a possibility that the user will be returned to the meeting place at a time much earlier than the meeting time.

  The present invention has been made in view of this point, and an object of the present invention is to provide a portable terminal device that can improve the convenience of the user in a sightseeing spot or the like when performing walking navigation.

  The mobile terminal device of the present invention is a mobile terminal device having a navigation function, and calculates a first average walking speed and a second average walking speed that is slower than the first average walking speed according to a schedule type. A first alarm notification time is calculated using the walking speed calculation means and the first average walking speed, and a second earlier than the first alarm notification time using the second average walking speed. Notification time calculating means for calculating an alarm notification time; and notification means for performing two-stage alarm notification according to the first alarm notification time and the second alarm notification time.

  ADVANTAGE OF THE INVENTION According to this invention, when performing walking navigation, the convenience of the user in a sightseeing spot etc. can be improved.

Functional block diagram showing a configuration of a mobile terminal device according to an embodiment of the present invention The figure which shows the specific example of operation | movement of the portable terminal device which concerns on embodiment of this invention.

  Hereinafter, a mobile terminal device according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a functional block diagram showing the configuration of the mobile terminal device 100 according to the embodiment of the present invention.

  In the mobile terminal device 100, the schedule storage unit 101 stores a user's schedule. The schedule stored in the schedule storage unit 101 is classified into a plurality of schedule types. In the following description, the schedule storage unit 101 stores a schedule during the user's bus tour, and the schedule during the bus tour is classified into two schedule types of “walking and moving” or “under sightseeing”. It shall be remembered.

  The walking speed measurement unit 102 measures the user's walking speed at regular intervals, and outputs the measurement result to the schedule determination unit 103.

  When the measurement result is output from the walking speed measurement unit 102, the schedule determination unit 103 acquires the schedule type of the schedule corresponding to the output time from the schedule storage unit 101. Then, the schedule determining unit 103 outputs the walking speed measurement result to the first storage unit 104 or the second storage unit 106 according to the schedule type. That is, the schedule determination unit 103 outputs the measurement result to the first storage unit 104 when the schedule type is “walking and moving”, and outputs the measurement result to the second storage unit when the schedule type is “under sightseeing”. It outputs to 106. Thus, the first storage unit 104 stores the walking speed measurement history when the schedule type is “walking and moving”, and the second storage unit 106 stores the walking speed when the schedule type is “under sightseeing”. The measurement history is stored.

The first storage unit 104 calculates, from the stored measurement history, an average value of walking speed (average value during movement) v ₁ when the schedule type is “walking and moving”, and calculates a calculation result as a first notification time. To unit 105 and route search unit 109.

The second storage unit 106 calculates an average value (walking average value) v ₂ of walking speed when the schedule type is “under sightseeing” from the stored measurement history, and the calculation result is a second notification time calculation unit. It outputs to 107.

  Here, as described above, since it takes time for sightseeing in a sightseeing spot, the walking speed is slower than the normal walking speed. Therefore, the average value during sightseeing is usually slower than the average value during movement. For example, the average value during sightseeing is 1 km / hour, while the average value during movement is 4 km / hour.

  The current position detection unit 108 detects the current position of the mobile terminal device 100 using GPS or the like, and outputs the detection result to the route search unit 109.

When the route search unit 109 starts the route search, (1) the current position of the mobile terminal device 100 or the departure position set by the user, (2) the sightseeing position set by the user, and (3) the return position set by the user The route of walking navigation is searched from (for example, the position of the meeting place), and the required time is calculated based on the distance of the search result and the moving average value. Then, the route search unit 109 calculates the expected arrival time t _s to return position and a required time and the route search starting time, outputs the calculated result to the first notification time calculating unit 105 and the second notification time calculation unit 107 To do.

  Further, the route search unit 109 calculates the distance d from the current position to the return position at any time during walking navigation, and outputs the calculation result to the first notification time calculation unit 105 and the second notification time calculation unit 107.

The first notification time calculation unit 105 calculates the first notification time by calculating d / v ₁ . The first notification time calculation unit _105, with respect to _{d / v 1> (t s} -t n) and alarm notification unit 110 when it becomes an instruction to the alarm notification to the user (alarm notification 1) . In addition, _{t n} is the current time.

Second notification time calculation unit 107 calculates a second notification time by calculation of d / _{v 2.} The second notification time calculation unit _107, with respect to _{d / v 2> (t s} -t n) and alarm notification unit 110 when it becomes an instruction to the alarm notification (alarm notification 2) to the user .

  The alarm notification unit 110 notifies the user of an alarm according to an instruction from the first notification time calculation unit 105 or the second notification time calculation unit 107.

Here, as described above, since v ₂ <v ₁ is normal, the alarm notification 1 is made later than the alarm notification 2.

  Next, a specific example of the operation of the mobile terminal device 100 will be described with reference to FIG.

  In FIG. 2, it is assumed that the user returns to the same return position A as the departure position A through the sightseeing positions B and C, where the departure position is A. Further, it is assumed that the average value during sightseeing is 1 km / hour and the average value during movement is 4 km / hour as described above, and the user is at the current position C, which is 2 km away from the departure position A.

In such an assumption, in order for the user to return from the current position C to the return position A, if the walking speed v ₁ moves, the user arrives at the return position A in 30 minutes, while the walking speed v ₂ may move. For example, it takes 2 hours to arrive at the return position A. Therefore, in such an assumption, alarm notification 1 is made at 16:30, 30 minutes before _ts = 17: 00, while alarm notification 2 is two hours before _ts = 17: 00, 15 0:00.

  As described above, according to the present embodiment, the alarm notification is performed in two stages in consideration of both the normal walking speed and the walking speed during sightseeing. When performing the walking navigation, it is possible for each user to select a necessary alarm notification in accordance with the characteristics of his / her walking speed and his / her preference, thereby improving user convenience.

  The present invention can be applied to all portable terminal devices having a navigation function.
