Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a navigation device that performs a route search based on a point input such as a destination and performs route guidance according to the searched route.
[0002]
[Prior art]
In the navigation system, when a map is displayed to search or register a point, operations such as moving the map (scrolling) or changing the scale are performed. Conventionally, a joystick capable of complex operation (moving operation in all directions) is used as the center of an operation device for moving around the screen using the remote control or moving the screen. In addition, a touch area in the scroll direction is displayed on the screen of the touch panel, the direction is touched to select and scroll, the scroll menu in eight directions is displayed, and one of them is scrolled by pointing with the mouse, There are those that use a trackball to scroll according to the direction and speed of rotation of the ball (see, for example, Japanese Patent Laid-Open Nos. 6-4025, 9-44084, and 9-81032).
[0003]
[Problems to be solved by the invention]
However, the conventional operation with a joystick is a combination of multi-directional and multi-axis (front / rear / left / right multi-direction + up / down) operations of “tilting” the stick in each direction and “pushing” the stick in the axial direction. Therefore, there is a problem that the user is likely to make an operation mistake such as pushing or pushing in an unintended direction. In addition, in the operation based on the joystick, the movement amount is determined by the operation amount and the operation time of “depressing” / “pressing” the stick, so that the user may exceed the desired point or stop in front. It is difficult to perform delicate operations. In the operation transition based on the joystick, the number of operations is small, and a complex operation can be performed. However, the load on one operation increases and the user tends to feel stress.
[0004]

It is a figure for demonstrating.
[0019]
On the screen that controls the display of the map in the navigation device according to the present invention, for example, a command button such as a set menu, movement, and zoom is displayed on the map as shown in FIG. . The set menu button is used when entering a point setting mode, the movement button is used when entering a mode for controlling the movement of a map, which will be described later, and the zoom is used when entering a mode for zooming the map. The close button is used to close the command button display, the menu button is used to enter the search mode, the re-speech button is used to listen to the output guidance voice again, and all routes are displayed. The button is used when it is desired to display all searched routes on the screen, and the re-search button is used when it is desired to re-search a route once searched with another route. The selection positions of these buttons move in a predetermined order according to the direction of the rotation operation of the jog dial, and the selection position is determined by the enter operation. If the direction of the rotation operation of the jog dial is reversed, the moving order of the selected position is reversed. Here, FIG. 4 shows an example of the screen in the mode in which the transition is made when the movement button is determined as the selection position and the movement direction axis is selected. In addition, each of them is set as a moving direction, and button areas for “return” and “zoom” for canceling the mode are provided. In the screen shown in FIG. 4, the selection position highlighted by the jog dial according to the rotation operation is divided into eight areas in the movement direction and the “Back” and “Zoom” buttons are moved in order. To decide. For example, when the “Zoom” button is determined as the selection position, the screen performs a zoom control of the map, and when the “Return” button is determined as the selection position, the screen returns to the screen shown in FIG. If any area in the movement direction is determined as the selection position, the movement control of the map along the movement direction axis can be performed. In the state shown in FIG. 4, the area in the upper left direction is set as the selection position. When the enter operation is performed here, this movement direction axis is determined, and as shown in FIG. 5, the upper left direction corresponding to the movement direction axis and vice versa. The area of the lower right direction and the “return” button are left displayed, and the brightness of the buttons in other areas is extremely reduced, and the upper left direction is highlighted. In the screen shown in FIG. 5, the map is moved in the upper left direction in which the jog dial is highlighted in accordance with the rotation operation. When the jog dial rotation is stopped, the map stops moving and “Return” is highlighted.When the jog dial is rotated again in the same direction, the map moves in the upper left direction, but in the opposite direction. When the jog dial is rotated, the map moves in the opposite lower right direction. That is, the moving direction of the map is reversed according to the direction of the rotation operation of the jog dial while the moving direction axis is fixed. “Return” is used to change the movement direction axis, and when the jog dial is stopped and the enter operation is performed with “return” highlighted, the screen shown in FIG. 4 is displayed again.

Next, the flow of processing for controlling the movement of the map will be described with reference to FIG. First, the movement operation and scale call button shown in FIG. 4 are displayed when the movement selection position is determined on the screen of FIG. 3 (step S21). When the selected position is moved by the jog dial's rotation operation and enter operation is performed, it is determined whether the selected position is “move” (any of the eight selection areas on the outer periphery), “scale” (zoom), or “return”. (Step S22). In the case of “return”, the screen returns to the previous screen. In the case of “scale”, the process proceeds to step S31 of the process described later in FIG. S23). Next, it is determined whether the moving direction is the forward direction or the reverse direction according to the rotation operation of the jog dial (step S24), and the map is moved in the determined direction or the reverse direction according to each determination (steps S25, S26). Further, it is determined whether or not the jog dial rotation operation continues (step S27). If the rotation operation continues (YES), the process returns to step S24 and the same processing is repeated, and the rotation operation is performed. When it stops (in the case of NO), the highlighted display of the selected position is returned to the completion button “return” (step S28). Subsequently, it is determined whether the movement is resumed / completed (step S29). This is whether the jog dial has been rotated (restarted) or entered (completed). If restarted, the process returns to step S24 again, and if completed, the movement control of the map is completed.
[0021]
Further, the zooming process of the map performed in the case of “scale” in step S22 displays a scale button including a wide area button and a detail button as shown in FIG. 7 (step S31), and according to the direction of the rotation operation of the jog dial. It is determined whether the scale direction is the forward direction or the reverse direction (step S32). In the case of the forward direction, the zoom is performed on the wide area map (step S33), and in the case of the reverse direction, the zoom is performed on the detailed map (step S34). Further, it is determined whether or not the jog dial rotation operation is continued (step S35). If the rotation operation is continued (in the case of YES), the process returns to step S32 and the same processing is repeated to perform the rotation operation. Is stopped (in the case of NO), the highlighting of the selected position is returned to the completion button “RETURN” (step S36). Subsequently, it is determined whether the scale is resumed / completed (step S37). This is whether the jog dial has been rotated (restart) or entered at the selection position of the “return” button (completion). When restarting, the process returns to step S31 again. Complete zoom control. Note that the zooming of the map can be changed from either the “Zoom” button shown in FIG. 3 or the “Zoom” button shown in FIG.
