A car navigation device 1 shown in FIG. 1 is provided on a display unit 2 having a display unit such as a liquid crystal display panel and an upper surface (same screen) of the display unit 2, and can be operated by simultaneously touching a plurality of points. Multi-touch panel 3, map database 4 in which road map information and facility information associated with roads are stored (database is abbreviated as DB in the figure), and road map information and facility information stored in map database 4 Is displayed on the display unit 2, and a map management display unit 5 that performs a route search or the like to draw a route or a place of stay on a road map and manages a display state, and a first point for the multi-touch panel 3 and A signal processing unit 6 that detects each operation of the second point separately, and based on the detection signal of the signal processing unit 6, the first point In addition to detecting and providing the map management display unit 5 with a combination of the work content and the second operation content, a user operation receiving unit 7 for controlling the display state of the display buttons and the like displayed on the display unit 2 is provided. ing.

  The operation of the car navigation device 1 configured as described above will be described below in association with a general operation performed by the user. The user operates the car navigation device according to the procedure shown in the flowchart of FIG. That is, the departure place is designated in step S11. Subsequently, in step S12, it is determined whether the waypoint is determined in advance. If the waypoint is determined, the waypoint is designated in step S14. On the other hand, if the waypoint is not determined, the waypoint is searched in step S13, and then the place is set in step S14. Thereafter, the staying time at the waypoint is designated in step S15. Next, a destination is designated at step S16. A result of searching for a guidance route based on the designation information is displayed on the display unit 2.

  The search result displayed on the display unit 2 is stored as history information, and is used for the next guidance when the departure place and the destination are the same. At this time, the user may specify additional waypoints, change the order of waypoints, or select another route. Therefore, the user additionally designates a waypoint in step S17, or changes the order of the waypoints in step S18. Further, another route is selected in step S19 without specifying the waypoint or changing the order.

  The first embodiment of the present invention improves the operability when designating a waypoint in step S14, and the specific operation will be described below with reference to FIGS. First, the map management display unit 5 shown in FIG. 1 reads road map information stored in the map database 4 and displays it on the display unit 2. FIG. 3 shows a road map 20 displayed on the display unit 2 and a state of a finger operating the multi-touch panel 3 provided on the upper surface of the display unit 2. In this case, the road map 20 includes a branch point 21 handled as a node and a road 22 handled as a link. Further, the multi-touch panel 3 is subjected to a tracing operation of the road 22 in response to the pressing of the first point by the first finger 31 of the person, for example, the index finger, and the tracing operation is stopped near the branch point 21 and is stationary. 2 shows that the second point 32 is pressed by the second finger 32, for example, the middle finger.

  The multi-touch panel 3 is not limited to a finger, and can be operated with a touch pen, for example. However, since the present invention is premised on an operation with a finger, in each of the following embodiments, the first point will be described as a first finger and the second point will be described as a second finger. Of the operations on the multi-touch panel 3, the operation of moving the pressed finger along the road is “trace operation”, and the single press is “single click operation” or abbreviated “single click”. The operation to move (drag and drop) is referred to as “single click operation with movement” or abbreviated as “single click with movement”, and the quick double press is referred to as “double click operation” or “double click”. .

  1 and 3, when a trace operation and a double-click operation are performed on the multi-touch panel 3 provided on the upper surface of the display unit 2, the signal processing unit 6 presses the first finger 31 and the second finger 32. And the detection signal are added to the user operation reception unit 7. The user operation reception unit 7 traces the road 22 on the road map 20 in which an operation performed on the multi-touch panel 3 is performed in accordance with the pressing of the first finger 31 based on the signal applied from the signal processing unit 6. It is an operation, and it is detected that the trace operation is stopped in the vicinity of the branch point 21 and that the double-click operation of the second finger 32 is performed during the stop. Thus, the map management display unit 5 designates the trace operation trace 23 of the first finger 31 until the user operation reception unit 7 detects the second double-click operation, and the user operation reception unit 7 A point where the first finger 31 is pressed when the double-click operation of the second finger 32 is detected is designated as a transit point, a vehicle guidance route search is executed, and the result is drawn on the road map 20 of the display unit 2. To do.

  FIG. 4 is a flowchart showing a specific processing procedure of the map management display unit 5. Here, in step S101, during the designation of the route by the first finger, it is recognized that the first finger is being pressed while still. Next, in step S102, it is determined whether or not the second finger is double-clicked. If it is determined in step S102 that the double-click has been made, in step S103, the pressing point of the first finger is designated as a waypoint. If it is determined in step S102 that the double click has not been performed, the processes in steps S101 and S102 are repeated.

  Thus, according to the first embodiment, the waypoint can be specified without releasing the first finger 31 tracing the road from the multi-touch panel 3, so that the operability can be improved. .

<Second Embodiment>
In the second embodiment of the present invention, the waypoint is specified in step S14 and the stay time is specified in step S15 during the user operation procedure shown in FIG. In this case, the overall configuration of the car navigation apparatus is the same as that shown in FIG. FIG. 5 shows the road map 20 displayed on the display unit 2, and the first finger 31 is designated to designate the staying time at the waypoint after the waypoint designating operation described in the first embodiment. In the state where the vicinity of the branch point 21 is pressed and the single finger is moved with the second finger 32, that is, the second finger 32 is pressed near the first finger 31, and the second finger 32 is The state which moves in the direction away from the 1st finger 31 is shown.

  In this way, each operation of the first finger 31 and the second finger 32 performed on the multi-touch panel 3 is detected by the signal processing unit 6 in a distinguishable manner. Based on the detection signal of the signal processing unit 6, the user operation receiving unit 7 performs a tracing operation on the road 22 by the first finger 31, a double-clicking operation of the second finger 32 performed while the tracing operation is stationary, and thereafter A single click operation involving the movement by the second finger 32 is detected. As a result, the map management display unit 5 designates the trace 23 of the trace operation of the first finger 31 as a route, and uses the point where the first finger 31 is pressed at the time of detecting the double click operation of the second finger 32 as a transit point. Further, the distance between the pressing point of the first finger 31 and the pressing point after the single click operation accompanied by the movement of the second finger 32 is converted into time, and the obtained time is specified as the stay time at the waypoint. Then, the map management display unit 5 searches for the guidance route according to the designated route and waypoint, displays the result on the road map 20 of the display unit 2, and displays the stay time on a predetermined part of the display unit 2. To do.

  FIG. 6 is a flowchart showing a specific processing procedure of the map management display unit 5. Here, in step S201, it is recognized that the first finger is being pressed down while the route is designated by the first finger. Next, in step S202, it is determined whether or not the second finger is double-clicked. If it is determined in step S202 that the double-click has been made, in step S203, the point where the first finger is pressed is designated as a waypoint, and the process of step S204 is executed. If it is determined in step S202 that the double click has not been performed, the processes in steps S201 and S202 are repeated. In step S204, it is determined whether or not a single click involving the movement (drag) of the second finger has been performed. If a single click has been performed, the first finger pressing point and the second finger are determined in step S205. Specifies the staying time proportional to the distance of the point of pressing. If it is determined in step S204 that the single finger has not been clicked, it is determined in step S206 whether or not the first finger has moved. If it is determined that the first finger has not moved, the process returns to step S204 to move. If it is determined that the process has been performed, the process returns to step S201.

  As described above, according to the second embodiment, the route point and the stay time can be designated without releasing the finger tracing the road from the touch panel. Operability can be improved.

  In the second embodiment, when the single click with the movement of the second finger is performed only once, the distance between the pressing point of the first finger and the pressing point after the single operation with the movement of the second finger. However, instead of this, it is possible to set a stay time proportional to the amount of movement at the time of a single click accompanied by the movement of the second finger. Moreover, when the single click accompanied by the movement of the second finger is repeated a plurality of times, the total movement amount of the second finger can be designated as the staying time.

  In the second embodiment, the second finger is moved in the direction away from the point where the first finger is pressed and the single click accompanied by the movement is performed. However, the direction in which the second finger is brought closer to the point where the first finger is pressed. It is also possible to move to and perform a single click with movement. Further, the direction of moving away from the vicinity of the stationary first finger is positive, the direction of approaching the vicinity of the stationary first finger is negative, and the amount of movement of the single click accompanied by movement is added. The total can also be specified as stay time.

<Third Embodiment>
The third embodiment of the present invention improves operability when searching for a waypoint in step S13 during the user operation procedure shown in FIG. In this case, since the overall configuration of the car navigation apparatus is the same as that shown in FIG. 1, the description thereof will be omitted, and the operation will be described with reference to FIGS. FIGS. 7A and 7B show the road map 20 displayed on the display unit 2, and the multi-touch panel 3 performs a tracing operation on the road 22 with the first finger 31, while the tracing operation is stationary. A single click operation involving the movement of the second finger 32 performed near the one finger 31 and the locations of the facilities 41, 42, 43 in the vicinity where the first finger 31 is stationary are displayed on the road map 20. . Among these, FIG. 7A shows a case where L1 has a small amount of single-click movement accompanied by movement by the second finger 32, and FIG. This shows a case where L2 is large. Thereafter, as described above, it is assumed that the double click operation with the second finger 32 is performed.

  When the above-described operation is performed on the multi-touch panel 3, each operation is detected by the signal processing unit 6, and the detection signal is added to the user operation receiving unit 7. Based on the detection signal of the signal processing unit 6, the user operation reception unit 7 is accompanied by a movement by the second finger 32 performed while the tracing operation on the road 22 by the first finger 31 and the tracing operation by the first finger 31 are stationary. Detect single-click operations. The map management display unit 5 designates the road 22 on which the tracing operation is performed by the first finger 31 as a route, and the first finger 31 increases as the movement amount at the time of the single click operation accompanied by the movement by the second finger 32 increases. The locations of the facilities farther away from the facility at a distance from the stationary position are highlighted. For example, when the amount of movement at the time of a single click operation involving movement by the second finger 32 is small L1 as shown in FIG. 7A, the location where the near facility 41 is present is highlighted. When the movement amount at the time of the single click operation accompanied by the movement by the second finger 32 is a large L2 as shown in FIG. 7B, the position where the distant facility 43 exists is highlighted. If the amount of movement at the time of a single click operation involving movement by the second finger 32 is between L1 and L2, the location of the facility 42 that is intermediate in distance is highlighted. Thereafter, when a double-click operation by the second finger 32 is detected by the user operation receiving unit 7, the map management display unit 5 designates the facility being highlighted as a transit point.

  Here, the map management display unit 5 displays the outline of the corresponding facility on the display unit 2 when the location of the facility corresponding to the movement amount at the time of the single click operation accompanied by the movement by the second finger 32 is highlighted. When the single click operation with the movement by the second finger 32 is canceled, the details of the facility are displayed instead of the overview of the facility. The user can also perform the double-click operation with the second finger 32 described above after viewing the details of the facility.

  FIG. 8 is a flowchart showing a specific processing procedure of the map management display unit 5. Here, in step S301, it is recognized that the first finger is pressed down while the route is designated by the first finger. Next, in step S302, it is determined whether or not a single click with movement of the second finger has been performed. If it is determined in step S302 that a single click with the movement of the second finger has been performed, the process of step S303 is executed, and if it is determined in step S303 that the single click with the movement of the second finger has not been performed. Repeat steps S301 and S302. In step S303, the facility with the rank proportional to the distance between the pressing point of the first finger and the pressing point of the second finger is highlighted. Next, in step S304, it is determined whether or not double-clicking has been performed with the second finger. If double-clicking has been performed, the highlighted facility is designated as a transit point in step S305. If it is determined in step 304 that the second finger has not been double-clicked, it is determined in step S306 whether or not the first finger has moved. If it is determined that the first finger has not moved, step S306 is performed. Returning to the process of S304, if it is determined that the movement has been made, the process returns to the process of Step S301.

  As described above, according to the third embodiment, since it is possible to designate a facility of interest as a waypoint without releasing the finger tracing the road from the touch panel, the facility of interest is designated as a waypoint. The operability when specifying can be improved.

  In the third embodiment, according to the moving distance at the time of a single operation involving the movement of the second finger, highlights are displayed in order from the facility closest to the distance, but not only the distance but also “recommended degree” or the like It is also possible to order by.

<Fourth embodiment>
The fourth embodiment of the present invention improves the operability when the transit point is additionally designated in S17 during the user operation procedure shown in FIG. In this case, since the overall configuration of the car navigation apparatus is the same as that shown in FIG. 1, the description thereof will be omitted, and the operation will be described with reference to FIGS. 9A and 9B, when a route and a waypoint are designated in advance, the multi-touch panel 3 is operated by pressing the first finger 31 on a route on which an additional waypoint is to be inserted. An operation state and an operation state in which the first finger 31 is moved to the position where an additional waypoint exists and the multi-touch panel 3 is double-clicked by the second finger 32 are shown. A designated route 51 and a plurality of waypoints 61, 62, and 63 are displayed on the road map 20 shown in FIG. When another waypoint 64 is additionally designated between the waypoints 61 and 62, the first finger 31 is pressed on the route 51 between the waypoints 61 and 62. Then, as shown in FIG. 9B, the first finger 31 is moved to a point where the user wants to stay, and the second finger 32 is double-clicked while the first finger 31 is kept stationary. As a result, the point where the first finger 31 is pressed is designated as an additional waypoint 64.

  These operations include a single click operation involving a press on the path 51 displayed on the display unit 2 and a movement with the first finger 31 moving from the pressed position to the other, and a single click with a movement with the first finger 31. This corresponds to a double click operation with the second finger 32 performed after the movement of the operation. These operations are detected by the user operation receiving unit 7 via the signal processing unit 6. The map management display unit 5 detects the next waypoint for the route point pressed by the single click operation accompanied by the movement by the first finger 31, and when the double click operation by the second finger 32 is performed, The pressing point after the movement of the single click operation accompanied by the movement by the one finger 31 is designated as the waypoint 64 immediately before the next waypoint. Further, the map management display unit 5 adds a route point 64 between the route point 61 and the route point 62, executes a route search again, and redraws the result on the road map 20 of the display unit 2.

  FIG. 10 is a flowchart showing a specific processing procedure of the map management display unit 5. Here, the route and waypoint designated in advance in step S401 are displayed on the road map 20 to enter a standby state for a designation operation related to road guidance. Therefore, when the multi-touch panel 3 is operated, it is determined in step S402 whether or not a single click with movement is performed with the first finger. If it is determined in step S402 that a single click involving movement has been performed with the first finger, the next waypoint is detected from the route point where the first finger is pressed in step S403. If it is determined in step S402 that the single click has not been performed, the process returns to the standby state for the designated operation in step S401. After detecting the next waypoint in step S403, it is confirmed in step S404 that the first finger has moved and double-clicked with the second finger, and the processing in next step S405 is executed. In step S405, the position where the moved first finger is pressed is designated as the transit point immediately before the next transit point. Next, the route search is performed again in step S406, the obtained route and waypoint are redrawn, and the process returns to the standby state for the designation operation in step S401.

  As described above, according to the fourth embodiment, a stopover can be added by a single click operation accompanied by movement by the first finger and a double click operation by the second finger. Operability can be improved.

  In the fourth embodiment, an additional waypoint is specified immediately before a route point where a route search has been performed in the past, but an additional route point immediately after a route point where a route search has been performed in the past is specified. May have to be specified. In this case, the user operation reception unit 7 performs a single click operation involving pressing on the route displayed on the display unit 2 and movement by the first finger 31 moving from the pressed position to the other, and after the movement.
