Description

  The present invention relates to an electronic device in which a navigation application for causing the electronic device to execute a navigation function is installed, a control method for the electronic device, and a computer program.

  Conventionally, in a mobile information terminal such as a smartphone or a mobile phone, and an electronic device such as a personal computer, various navigation functions can be executed by installing a navigation application and starting the installed navigation application. . As a navigation function to be executed, for example, a map image around the current position is displayed to the user, a guide route from an arbitrarily set departure point to a destination is displayed, or a destination along the guide route is displayed. It is possible to provide travel guidance to the ground. Here, in order to properly operate the navigation function, it is important to accurately specify the current position of the electronic device (that is, the user).

  Here, the current position of the user is generally detected by a GPS built in the electronic device. However, since the detection accuracy of the current position by the GPS is not high, there is a difference between the detected current position and the actual current position. In addition, in a navigation apparatus or the like installed in a vehicle, the current position is detected more accurately by using information (self-contained navigation information) obtained from a distance sensor and an angle sensor mounted on the vehicle in addition to GPS. However, self-contained navigation information cannot be used with a portable information terminal or the like.

  Furthermore, immediately after the navigation application is activated, there are many cases where the user is particularly in a situation where the accuracy of the GPS in the building or the like is particularly deteriorated. Therefore, for example, in Japanese Patent Application Laid-Open No. 2009-58242, the vehicle position and the vehicle orientation when the navigation system is stopped are stored, and when the navigation system is activated next time, the stored vehicle position and vehicle orientation are respectively set as the initial position and the initial orientation. The technology to be proposed is proposed.

  Next, a navigation application activation processing program executed by the CPU 11 in the communication terminal 1 having the above configuration will be described with reference to FIG. FIG. 5 is a flowchart of the navigation application activation processing program according to this embodiment. Here, the navigation application activation processing program is executed at predetermined intervals after the communication terminal 1 is turned on, activates the navigation application installed in the communication terminal 1, and is specified on the map after the navigation application is activated. This is a program for setting the initial position of the communication terminal 1 (ie, user 5). Further, the program shown in the flowchart of FIG. 5 below is stored in the memory 12 provided in the communication terminal 1 and executed by the CPU 11.

  First, in step (hereinafter abbreviated as S) 1 in the navigation application activation processing program, the CPU 11 displays a top screen 25 (see FIG. 3) on the display 18. The top screen 25 displays activation icons 26 to 28 for activating applications installed in the communication terminal 1.

  Next, in S2, the CPU 11 determines whether or not a predetermined operation for starting activation of the navigation application has been accepted. Specifically, among the icons displayed on the top screen 25 (see FIG. 3), when the activation icon 26 associated with activation of the navigation application is selected (for example, touched by a touch panel), the navigation application It is determined that a predetermined operation for starting activation has been received.

  And when it determines with having received predetermined operation for starting starting of a navigation application (S2: YES), it transfers to S3. On the other hand, when it is determined that a predetermined operation for starting activation of the navigation application is not accepted (S2: NO), the navigation application activation process program is terminated.

  In S3, the CPU 11 executes a navigation application activation process. As a result, the activation process is completed after a predetermined time (for example, 5 seconds) has elapsed, and a navigation screen 29 as shown in FIG. Note that the current position mark 31 displayed on the navigation screen 29 immediately after activation is displayed with respect to the initial position set in S7 or S9 described later. Thereafter, the user can perform navigation functions such as route search and facility search by operating the various operation buttons 32 to 34 displayed on the navigation screen 29 again.

  Next, in S4, CPU11 acquires the point (henceforth an input history point) input into the communication terminal 1 in the past based on a user's operation. Here, the input history point is, for example, a memory point (including a facility) registered in advance by the user such as a home, or a point (including a facility) set as a destination in the past in the navigation application. There is a destination history. The memory point and destination history are stored in the memory 12, and the CPU 11 acquires the input history point by reading the memory point and destination history from the memory 12.

Not all the points included in the destination history are input history points, but only the most recently set destination (hereinafter referred to as the nearest destination) among the destinations stored in the destination history. May be used as the input history point. Further, only the nearest destination that is the nearest destination and is determined to have arrived by the user may be set as the input history point. As conditions for determining that the user has arrived at the destination set in the navigation application, for example, there are the following conditions (A) to (C).
(A) When a guidance for notifying the arrival at the destination is output in the navigation application.
(B) When the distance from the user to the destination is within a predetermined distance (for example, 500 m).
(C) The time required for the user to arrive at the destination is within a predetermined time (for example, 1 minute).
When any one or a plurality of conditions (A) to (C) is satisfied, it is determined that the user has arrived at the destination set in the navigation application.

  Thereafter, in S5, the CPU 11 acquires the current position of the communication terminal 1 (that is, the user 5). The acquisition of the current position in S4 is performed using the GPS 20 built in the communication terminal 1. Moreover, you may use apparatuses and sensors other than GPS20 for acquisition of a present position.

  Subsequently, in S6, the CPU 11 determines whether or not there is an input history point within 500 m from the current position of the communication terminal 1 (that is, the user 5) acquired in S5. It should be noted that the distance used as the determination criterion in S6 can be set to a distance other than 500 m (for example, 300 m or 800 m). It is desirable to set an appropriate distance according to the accuracy of the GPS 20.

  If it is determined that there is an input history point within 500 m from the current position of the communication terminal 1 (that is, user 5) acquired in S5 (S6: YES), the process proceeds to S8. On the other hand, when it is determined that there is no input history point within 500 m from the current position of the communication terminal 1 (that is, the user 5) acquired in S5 (S6: NO), the process proceeds to S7.

  In S7, the CPU 11 sets the current position of the communication terminal 1 (that is, the user 5) acquired in S5 as an initial position. As described above, the initial position is the current position of the communication terminal 1 (user 5) that is first identified on the map after the navigation application is activated. Then, in the navigation application immediately after activation, a navigation screen 29 displaying the current position mark 31 at the initial position set in S7 is displayed on the display 18 together with the map image 30 (FIG. 4). As a result, the user can specify the current position on the map. When a route search is subsequently performed, the route search is performed using the initial position set in S7 as a departure point.

  On the other hand, in S8, the CPU 11 determines whether or not there is an input history point within 100 m from the current position of the communication terminal 1 (that is, the user 5) acquired in S5. It should be noted that the distance used as the determination criterion in S8 can be set to a distance other than 100 m (for example, 50 m or 150 m). It is desirable to set an appropriate distance according to the accuracy of the GPS 20.

  If it is determined that there is an input history point within 100 m from the current position of the communication terminal 1 (that is, the user 5) acquired in S5 (S8: YES), the process proceeds to S9. On the other hand, when it is determined that there is no input history point within 100 m from the current position of the communication terminal 1 (that is, the user 5) acquired in S5 (S8: NO), the process proceeds to S10.

  In S9, the CPU 11 sets the input history point determined to be within 100 m from the current position in S8 as the initial position. As described above, the initial position is the current position of the communication terminal 1 (user 5) that is first identified on the map after the navigation application is activated. For example, in the example shown in FIG. 6, the home 42 of the user that is one of the input history points is within 100 m from the current position 41 of the communication terminal 1 (that is, the user 5) acquired in S5. Is set to the initial position. If there are a plurality of corresponding input history points, the input history point that is closest to the current position of the communication terminal 1 (that is, the user 5) acquired in S5 or the highest priority point (for example, home) ) Should be set to the initial position. Then, in the navigation application immediately after activation, the navigation screen 29 displaying the current position mark 31 at the initial position set in S9 together with the map image 30 is displayed on the display 18 (FIG. 4). That is, by performing the process of S9, the position of the current position mark 31 displayed on the navigation screen 29 immediately after startup is corrected from the position detected by the GPS 20 to a more appropriate position. It is possible to accurately guide the current position of the user. Further, when a route search is performed thereafter, the route search is performed with the initial position set in S9 as a departure point, so that a more accurate route search is possible.

  For example, in the example shown in FIG. 7, the home 42 of the user, which is one of the input history points, is within 100 m from the current position 41 of the communication terminal 1 (that is, the user 5) acquired in S5. The initial position 43 of the communication terminal 1 (user 5) is set. In the example illustrated in FIG. 7, the position of the user detected by the GPS 20 and the position of the home are extremely close. Therefore, the GPS 20 has low accuracy. ) Is estimated that the current position of the user is erroneously detected. Therefore, in S9, the CPU 11 performs a process of correcting the current position of the user to the home 42 which is the actual current position of the user. Then, the user specified on the map immediately after starting the navigation application by setting the corrected position as the initial position of the communication terminal 1 (user 5) specified on the map after starting the navigation application. The position of the user (that is, the position of the user guided in the navigation application) and the actual user position can be prevented from greatly differing.

  Further, when the input history point determined to be within 100 m from the current position in S8 is a facility having a partner parking lot, the partner parking lot of the input history point may be set as the initial position.

  On the other hand, in S10, the CPU 11 outputs a sentence or a sound for confirming to the user whether or not to change the initial position to the input history point determined to be within 500 m from the current position in S6. For example, if you have a home within 500m from your current location, “Are you sure you want to change your current location to your home? The sentence or voice is output. Furthermore, when there are a plurality of input history points determined to be within 500 m from the current position in S6, it may be confirmed which input history point to change to.

  Thereafter, in S11, the CPU 11 has selected that the user's response to the confirmation text or voice output in S10 is to change the initial position to an input history point determined to be within 500 m from the current position in S6. It is determined whether it is an answer. Note that the user may reply by an operation by the input operation unit 19 or may reply by voice using a voice recognition system.

  And when a user chooses to change an initial position into an input history point (S11: YES), it shifts to S9. Then, the input history point determined to be within 500 m from the current position in S6 is set as the initial position.

  On the other hand, when the user selects not to change the initial position (S11: NO), the process proceeds to S7. Then, the current position of the communication terminal 1 (that is, the user 5) acquired in S5 is set as an initial position.

As described above in detail, in the communication terminal 1, the control method of the communication terminal 1, and the computer program executed in the communication terminal 1 according to the present embodiment, when the navigation application is activated, the current position of the communication terminal 1 is determined. If there is an input history point within a predetermined distance of the detected current position of the communication terminal 1 detected (S5), the input history point is set to the initial position of the user specified on the map in the navigation application after activation. Since the setting is made (S9), in the communication terminal 1 in which the navigation application is installed, the deviation that occurs between the initial position of the user specified on the map and the actual current position of the user after the navigation application is activated is eliminated. It becomes possible. As a result, it is possible to guide an accurate user's current position in a navigation application immediately after activation, or to search for an accurate route to a destination. In addition, based on the positional relationship between the electronic device and the input history point when the navigation application is activated, it is possible to set an input history point appropriate for the user's initial position as the user's initial position.
In addition, when there is a memory point such as a home within a predetermined distance of the detected current position of the communication terminal 1, the memory point is set to the initial position of the user specified on the map in the navigation application after activation. In a situation where the user who started the navigation application is likely to be located at the memory location, the initial position of the user specified on the map after the navigation application is started can be set accurately.
In addition, when there is a destination set by the navigation application in the past within a predetermined distance of the detected current position of the communication terminal 1, the initial of the user specified on the map in the navigation application after starting the destination In the situation where the user who started the navigation application is likely to be located at the destination set in the past, the initial position of the user specified on the map after the navigation application is started is accurately set. It becomes possible to set.
In addition, when there is a destination set by the navigation app most recently within a predetermined distance from the detected current position of the communication terminal 1, the initial of the user specified on the map in the navigation app after starting the destination In the situation where the user who started the navigation app is likely to be located at the most recently set destination, the initial location of the user specified on the map after launching the navigation app is accurate. It becomes possible to set.
In addition, when there is a destination set by the navigation app most recently within a predetermined distance of the detected current position of the communication terminal 1 and determined that the user has arrived, in the navigation app after starting the destination Since it is set to the initial position of the user specified on the map, in the situation where the possibility that the user who started the navigation application is located at the destination set most recently is displayed on the map after starting the navigation application It becomes possible to accurately set the initial position of the identified user.
In addition, when the navigation app outputs a notification that the destination has been reached, it is determined that the user has arrived at the destination set in the navigation app, so the user has arrived at the nearest destination. It is possible to accurately determine whether or not there is.
In addition, when the distance from the user to the destination set in the navigation application is within a predetermined distance, it is determined that the user has arrived at the destination set in the navigation application. It is possible to accurately determine whether or not the user has arrived.
In addition, when the time required for the user to arrive at the destination set in the navigation application is within a predetermined time, it is determined that the user has arrived at the destination set in the navigation application. It is possible to accurately determine whether or not the user has arrived at the destination.
In addition, when the input history point is a facility having a partner parking lot, the partner parking lot of the input history point is set to the user's initial position. However, it is possible to eliminate the deviation that occurs between the initial position of the user specified on the map after the activation of the navigation application and the actual current position of the user.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in the present embodiment, the communication terminal 1 executes the processing of S1 to S11 of the navigation application activation processing program (see FIG. 5), but the information center 4 may execute a part or all of the processing. good.

  Moreover, it is good also as a structure which is not performed about the process of S5-S8, S10, and S11 among navigation application starting process programs (refer FIG. 5). In this case, the input history point acquired in S4 is set as the initial position (S9). However, when there are a plurality of input history points, it is desirable that the input history point selected as appropriate is set as the initial position. For example, an input history point closest to the current position of the communication terminal 1 can be set as an initial position, or an input history point input most recently in the communication terminal 1 can be set as an initial position.

  In the present embodiment, a touch panel is used as the operation means of the communication terminal 1 and the navigation application is activated by touching an icon displayed on the top screen 25. However, operation means other than the touch panel (for example, Icon, mouse, button, cross key, keyboard) or the like.

  Moreover, in this embodiment, although it is set as the structure which detects the present position of the communication terminal 1 by GPS20 built in the communication terminal 1, it is good also as a structure which detects the present position of the communication terminal 1 using means other than GPS20. .

  In the present embodiment, a memory point that is a point (including a facility) registered in advance by the user such as a home as an input history point, or a point (including a facility) that has been set as a destination in the past in the navigation application. Although a certain destination history is used, any other point may be used as long as it is a point previously input to the communication terminal 1 based on a user operation. For example, it may be a point where the user has performed a point search in the past.

  In the present embodiment, each time the application program is started, it is determined whether or not there is an input history point around the current position of the communication terminal 1. If there is an input history point, the initial position is set at the input history point. However, only when a specific navigation application activation method is performed (for example, when a shortcut icon is activated), the initial position setting process for the input history point may be performed. good.
