Hereinafter, each application will be described.
First, each application accepts a flick operation that traces the touch panel 102 upward or downward as a scroll instruction, accepts a user pinch-in operation as a user reduction instruction, and accepts a user pinch-in operation as a user enlargement instruction. .
Hereinafter, each application will be described.
First, the navigation application 111 will be described.
First, as shown in FIG. 2, the storage device 106 stores map data representing a map and a facility database as navigation data used by the navigation application 111 for processing.
In the facility database, facility data provided corresponding to each of the plurality of facilities is registered, and the name, type, coordinates, and the like of the facility are registered in each facility data.
Then, the navigation application 111 uses the map data recorded in the storage device 106 to calculate the current position of the vehicle using the GPS receiver 107 and the like, and the waypoint and destination according to the user operation. Setting, searching for a route via the set waypoint to the set destination, setting the searched route as a recommended route, and guiding the user to the recommended route to the destination are performed.

  Then, the navigation application 111 guides the recommended route to the destination by displaying a mark 202 indicating the current position, a recommended route 203 and a mark 204 indicating the destination on a map 201 around the current position as shown in FIG. This is done by displaying the displayed navigation image on the display device 101.

  Further, as shown in FIG. 3 a 210, the navigation application 111 performs a pinch-out operation, which is a user operation for expanding the interval between two fingers touching the touch panel 102 while touching the two fingers on the display of the map 201. Accepting from the user as an enlargement instruction, touching the touch panel 102 on the display of the map 201 as shown in FIG. 3b220 on the contrary, as shown in FIG. A pinch-in operation, which is a user operation that narrows the interval between two fingers while touching the two fingers, is accepted as a reduction instruction, and as shown in FIG.

In addition, the navigation application 111 always or in response to a user operation during a period in which the calculated current position indicates that the car is traveling on a general road while the recommended route is set. The process guide process shown in FIG. 4 is performed.
As shown in the figure, in this process guide process, first of all the points that will be passed when proceeding according to the recommended route, the intersection that will change the course such as turning left and right when proceeding according to the recommended route The target points are sorted in the order of passage along the recommended route with the route change intersection, the waypoint, and the destination as the target points (step 402).

Then, the first target point, that is, the target point that will pass first is set as the reference target point (step 404).
Then, a process guide window as shown in FIG. 5a is displayed (step 406), and the names of n target points (n = 3 in the figure) after the reference target point and the passing direction of the target point are displayed in the process guide window. And point information 501 indicating the required travel time / distance to the target point, and progress lane information 502 indicating a lane to be driven at a point in front of the n target points are displayed from the bottom to the top in the order of passage ( Step 408). Here, the progress lane information 502 of the point before the point corresponding to the point information 501 is displayed below the point information 501.

Then, the generation of a scroll instruction from the user (step 410) and the generation of a user reduction instruction (step 412) are monitored.
When a scroll instruction is generated (step 410), the reference target point is changed in accordance with the scroll direction of the scroll instruction (step 414), and the process of step 408 is performed again to scroll the display of the process guide window. . Here, in step 414, if the scroll direction is the downward direction, the target point as the reference target point is changed so that the order in the order after the sorting of the target points serving as the reference target points becomes larger. If the scroll direction is the upward direction, the target point as the reference target point is changed so that the order in the order after the sorting of the target points serving as the reference target points becomes smaller.

  On the other hand, when the user's reduction instruction is generated (step 412), as shown in FIG. 5b, m (m> n, m = 5 in the figure) target points after the reference target point in the process guide window. This point information 501 is displayed from the bottom to the top in the order of passage in the form in which the traveling lane information 502 before the target point is juxtaposed to the right (step 416).

Then, the generation of a scroll instruction from the user (step 418), the generation of a user enlargement instruction (step 420), and the generation of a user reduction instruction (step 422) are monitored.
When the scroll instruction is generated (step 418), the reference target point is changed according to the scroll direction of the scroll instruction (step 424), and the process of step 416 is performed again to scroll the display of the process guide window. .
Further, when a user enlargement instruction is generated (step 420), the process guide window display is returned to the display form of FIG. 5a by returning to the process of step 408.
When the user's reduction instruction is stopped (step 422), the target point where the traveling lane guide is required among the target points is set as the display point, and as shown in FIG. The point information 501 of the m display points after the point is displayed from the bottom to the top in the order of passage in the form in which the traveling lane information 502 before the target point is juxtaposed horizontally (step 426). In step 426, a thinning mark 510 is displayed between two adjacent display points where there is a target point that has not become a display point in between. Here, a target point that does not require a traveling lane guide is a target point that has only one lane at the previous point, a target point that advances from all the lanes at the previous point in the course change direction at the target point, etc. . However, in step 426, if there is a target point that does not become a display point between the current position and the first display point, the thinning is also performed under the point information of the first display point that passes. The mark 510 is displayed.

  The display of the travel guide window shown in FIG. 5c does not need to receive a traveling lane guide from the display of the travel guide window of FIG. 5b. Therefore, the display of “D intersection”, which is low useful information for the user, is displayed. Since it is thinned out and it is convenient to receive the traveling lane guide, “F intersection”, which is information more useful to the user, is added. In addition, a thinning mark 510 is provided for allowing the user to recognize that the thinned target point exists at the position where the display is thinned.

That is, the display of the travel guide window shown in FIG. 5c is such that only the intersections that are more useful for the user and need the traveling lane guide are displayed than the display of the travel guide window shown in FIG. 5b. It becomes.
Then, the generation of a scroll instruction from the user (step 428) and the generation of a user enlargement instruction (step 430) are monitored.
When the scroll instruction is generated (step 428), the reference target point is changed according to the scroll direction of the scroll instruction (step 432), and the process of step 426 is performed again to scroll the display of the process guide window. .
Further, when a user enlargement instruction is generated (step 430), the process guide window display is returned to the display form of FIG. However, when a user enlargement instruction is generated (step 430), the process may return to step 408 to return the display of the process guide window to the display form of FIG. 5a.

The process guide process performed by the navigation application 111 has been described above.
Next, the navigation application 111 is in a state where the recommended route is set, and the calculated current position indicates that the car is traveling on the highway at all times or in response to a user operation. The highway process guide processing to be performed will be described.
FIG. 6 shows the procedure of this highway route guide process.
As shown in the figure, in this expressway process guide process, first of all the points that will be passed when proceeding according to the recommended route, the expressway attached facility, the route change intersection, the waypoint, and the destination are the target points. The target points are sorted in the order of passage (step 602). Here, the expressway ancillary facilities are ICs (interchanges), SAs (service areas), PAs (parking areas), toll gates, and the like of the expressways.

Then, the first target point, that is, the target point that will pass first is set as the reference target point (step 604).
Then, a process guide window as shown in FIG. 7a is displayed (step 606), and the facility types, names, and target points of n target points after the reference target point (n = 4 in the figure) are displayed in the process guide window. The high speed point information 701 representing the required travel time / distance is displayed from the bottom to the top in the order of passage (step 608).

Then, the generation of a scroll instruction from the user (step 610) and the generation of a user reduction instruction (step 612) are monitored.
When the scroll instruction is generated (step 610), the reference target point is changed according to the scroll direction of the scroll instruction (step 614), and the process of step 608 is performed again to scroll the display of the process guide window. .
On the other hand, when the user's reduction instruction is generated (step 612), the target points excluding the IC that is simply passed through are set as the display points, and as shown in FIG. The high speed point information 701 of the display point is displayed (step 616). In step 616, a high-speed thinning mark 710 is displayed between two adjacent display points where there are target points that have not become display points in between. Here, an IC (interchange) that simply passes through is an IC that does not use the IC to get on and off the expressway.
However, in step 616, if there is a target point that does not become a display point between the current position and the first display point, the thinning is performed under the point information of the first display point. A mark 710 is displayed.

  Now, since the display of the process guide window shown in FIG. 7b is an IC that simply passes through the display of the process guide window of FIG. 7a, the information “A IC” and “C IC” that are less useful to the user are displayed. ”Is thinned out, and“ E IC ”and“ F toll gate ”, which are information of facilities actually used, which are more useful for the user, are added. In addition, a high-speed thinning mark 710 for allowing the user to recognize that the thinned target point exists at the position where the display is thinned is shown.

Then, the generation of a scroll instruction from the user (step 618), the generation of a user enlargement instruction (step 620), and the generation of a user reduction instruction (step 622) are monitored.
When the scroll instruction is generated (step 618), the reference target point is changed according to the scroll direction of the scroll instruction (step 624), and the process of step 616 is performed again to scroll the display of the process guide window. .
Further, when a user enlargement instruction is issued (step 620), the process guide window display is returned to the display form of FIG. 7a by returning to the process of step 608.
When the user's reduction instruction is generated (step 622), the target spot excluding the IC that simply passes through the PA is set as the display spot, and as shown in FIG. The high speed point information 701 of n display points is displayed (step 626). In step 626, a high-speed thinning mark 710 is displayed between two adjacent display points where there are target points that have not become display points in between. However, in step 626, if there is a target point that has not become a display point between the current position and the first display point, the thinning is also performed under the point information of the first display point that passes. A mark 710 is displayed.

  Now, the display of the process guide window shown in FIG. 7c is thinned out from the display of the process guide window of FIG. In addition, the display of “G intersection”, which is information of a course change intersection with higher usefulness, is added. In addition, a high-speed thinning mark 710 for allowing the user to recognize that the thinned target point exists at the position where the display is thinned is shown.

Then, the generation of the scroll instruction from the user (step 628) and the generation of the user enlargement instruction (step 630) are monitored.
When the scroll instruction is generated (step 628), the reference target point is changed in accordance with the scroll direction of the scroll instruction (step 632), and the process of step 626 is performed again to scroll the display of the process guide window. .
When the user enlargement instruction is generated (step 630), the process guide window is returned to the display form of FIG. 7b by returning to the process of step 616.
Heretofore, the highway route guide process performed by the navigation application 111 has been described.
Next, when the navigation application 111 is instructed to search for facilities along the route by the user in a state where the recommended route is set, the facility database is searched to search for facilities located along the recommended route. The search facility display process shown in FIG.
As shown in the figure, in the search facility display process, the searched facilities are set as the target facilities, and the target facilities are sorted in the passing order along the recommended route (step 802).
Then, the first target facility, that is, the target facility to be passed first is set as the reference target facility (step 804).
Then, a facility window as shown in FIG. 9a is displayed (step 806), and facility information 901 indicating the names of n (n = 4 in the figure) target facilities after the reference target facility is displayed in the facility window. Along with an information button 902 for receiving an instruction to display detailed information such as the location of the facility, the information is displayed from the bottom to the top in order of passage (step 808).

Then, the generation of a scroll instruction from the user (step 810) and the generation of a user reduction instruction (step 812) are monitored.
When the scroll instruction is generated (step 810), the reference target facility is changed in accordance with the scroll direction of the scroll instruction (step 814), and the display of the facility window is scrolled by performing the processing of step 808 again.
On the other hand, when the user's reduction instruction is generated (step 812), the target facility on the traveling lane side (the target facility on the left side of the road when viewed in the traveling direction if left-hand traffic) is set as the display facility. As shown in 9b, facility information 901 of n display facilities after the reference target facility is displayed in the facility window (step 816). In step 816, a thinning mark 910 is displayed between two adjacent display facilities where the target facility that has not become a display facility exists. However, in step 816, if there is a target facility that does not become a display facility between the current position and the first display facility that passes through, there is also a space under the facility information of the display facility that passes first. A pull mark 910 is displayed.

  The facility window display shown in FIG. 9b is a facility “convenience” that is less useful for the user because it is information on the facility window that is not on the traveling lane side and is difficult to use from the facility window display of FIG. 9a. “Store D” and “Convenience Store B”) are thinned out, and “Convenience Store Y” and “Convenience Store X”, which are highly useful information for users because they can be used from the lane, are added. It has become a thing. A thinning mark 910 is provided to allow the user to recognize that the thinned target facility exists at the position where the display is thinned.

Then, the generation of a scroll instruction from the user (step 818) and the generation of a user enlargement instruction (step 820) are monitored.
When the scroll instruction is generated (step 818), the reference target facility is changed according to the scroll direction of the scroll instruction (step 822), and the display of the facility window is scrolled by performing the process of step 816 again.
When the user enlargement instruction is generated (step 820), the display of the facility window is returned to the display form of FIG. 9a by returning to the processing of step 808.
The search facility display process performed by the navigation application 111 has been described above.
The navigation application 111 has been described above.
Returning to FIG. 1, the telephone application 112 uses the voice input / output device 105 for input / output of call voice and the mobile phone function using the mobile communication function of the connected mobile communication device 2 for sending / receiving call voice. It is an application that provides.
Next, the mail application 113 is an application that provides a mobile communication function of the connected mobile communication device 2 and a function for transmitting and receiving an electronic mail or a message used for data communication.
Next, the address book application 114 will be described.
First, as shown in FIG. 10, the storage device 106 stores an address database and an address use frequency table as address book data used by the address book application 114 for processing.
The address database stores address data registered by the user for each of the acquaintances. Each address data includes an address identifier that becomes an identifier of the address data, the name of the acquaintance, the telephone number of the acquaintance, the address of the acquaintance, the acquaintance. You can register your e-mail address.
The address usage frequency table has entries (each row in the figure) provided corresponding to each address data, and an address identifier of the corresponding address data is registered in each entry. In addition, if you make a call using the phone number registered in the address data and if you send an e-mail or message using the e-mail address registered in the address data, the address data is used. In each entry of the address usage frequency table, the usage frequency of the address data corresponding to the user and the usage history of the address data corresponding to the user are registered.

In such a configuration, when the address book application 114 is instructed to display the address book by the user, the address book application 114 performs an address book display process shown in FIG.
As shown in the figure, in this address book display process, first, the names registered in each address data of the address database are used as the target names, and the target names are sorted in alphabetical order and alphabetical order (step 1102).
Then, the first target name after sorting is set as the reference target name (step 1104).
Then, an address book window as shown in FIG. 12a is displayed (step 1106), and the target name of n (n = 4 in the figure) target names after the reference target name is displayed in the address book window in the order after sorting. The name information 1201 is displayed from top to bottom according to the sorted order (step 1108). Here, as shown in the figure, in the address book window, an instruction for calling (calling) a call to the telephone number registered in the address data of the name represented by the name information 1201 is displayed on the right side of the displayed name information 1201. A telephone button 1202 for accepting and a mail button 1203 for accepting an instruction to generate a send mail to the mail address registered in the address data of the target name are also displayed.

  Then, if the telephone button 1202 is operated by the user, the address book application 114 sends the telephone number to the telephone number registered in the address data of the name represented by the name information 1201 in which the telephone button 1202 is operated. While making a telephone call (calling), registering the current usage in the usage history of the address data entry of the name represented by the name information 1201 in which the telephone button 1202 is operated in the address usage frequency table, and the usage history The address usage frequency including the current usage is calculated and the entry usage frequency is updated.
