DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a navigation system according to the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing an example of a touch panel monitor screen in an embodiment of an application example of a navigation system according to the present invention to a car navigation system. FIG. 2 is a simplified plan view showing a basic configuration of a touch panel switch arrangement in a touch panel monitor, and FIG. 3 is a configuration block diagram for displaying a monitor screen based on position data detected by the touch panel switch.

As shown in FIG. 2, the touch panel operates in the X-axis direction and the Y-axis direction (x1 to x1) with respect to the monitor display screen.
Many sensors are arranged in (1, y1 to y8). For the arrangement of these sensors, existing touch panel sensors can be used.For example, by pressing a set of grid electrodes arranged in the vertical direction at the intersection of the grid-like arrangement, a set of upper and lower corresponding contact points is pressed. Is closed and the resistance or the like generated at that time is detected to detect the position of the pressed portion, or an infrared light emitting portion and an infrared light receiving portion are arranged on the opposite sides in the X-axis direction and the Y-axis direction, and the A configuration in which the pressed part (finger touch part) is detected by detecting a state in which the infrared light from the infrared light emitting part is blocked by the finger when the finger is touched.

For example, in FIG. 2, the fifth crossing position # from the right with respect to the X axis and the third crossing position from the top with respect to the Y axis #
When the user touches the second part, the positions are detected as x5 and y3 by the sensor.

Next, the present embodiment will be described with reference to FIG. 1. On a monitor screen on which a map screen is displayed, 8 circles on each circumference of an inner circle and an outer circle surrounding a center point of the screen are displayed. An arrow indicating the scroll direction is displayed at the direction position. A scroll operation is executed in the direction by touching an arbitrary arrow among them. Here, eight inner circle scroll arrows are group A arrows (A1 to A8), and eight outer circle scroll arrows are Arrows of group B (B1 to B8). The display of these arrows on the screen can be performed by operating the scroll switch 10 arranged on the side of the screen of the monitor or by touching an arbitrary position on the screen.

In FIG. 1, reference numeral 11 denotes a switch for displaying a menu screen of the navigation system;
Is a zoom switch for enlarging the screen display. When the screen other than the group A and the group B is touched, the arrow display is deleted and the display returns to the normal navigation display.

When the arrow of the group A is touched, a scroll operation is performed in the direction of the touched arrow, and when it is determined that the operator has scrolled to the target position, the finger is released from the screen. Stops scrolling.

On the other hand, when the arrow of group B is touched,
A scroll operation is performed in the direction of the touched arrow,
Until the finger is released from the screen, the same scrolling operation as when the finger of the group A is touched is executed. However, even when the operator releases the finger from the screen, the scrolling operation is intermittent (intermittent scrolling operation). ). In order to determine that the scroll has reached the target position and to stop the subsequent scrolling operation, it is sufficient to touch a part other than the arrow in the group A. The scroll operation may be stopped by any other means such as a separate switch.

Referring to FIG. 3, position information detected by the touch panel switch 1 (for example, the above x5 and y3)
Is input to the input data processing unit 2, processed, and sent to the display processing unit 3. In the display processing unit 3 to which the data from the input data processing unit 2 has been input, the display mode on the monitor screen is determined and output to the display control unit 4. The display control unit 4
Control for displaying a monitor screen of the display unit 5 is performed.

Next, the processing procedure in this embodiment is shown in FIG.
This will be described with reference to the flowchart shown in FIG.

First, the scroll operation is started (step S1), and the scroll direction arrows of the group A and the group B are displayed by the operation as described above (step S2). Then, the arrow of the group A or the group B is touched. It is determined whether or not it has occurred (step S3). Here, if it is determined that none of the arrows of the group A or the group B is touching, the display of the scroll arrow is deleted (step S11).

If it is determined in step S3 that the arrow of group A or B is being touched, it is determined which arrow of group A or B is being touched (step S4). .

If it is determined in step S4 that the arrow of the group A has been touched, it is determined which of the arrows A1 to A8 of the group A has been touched (step S4).
5), a scroll operation is performed in the direction of the finger touch arrow (step S7). This scroll operation moves the map display. Subsequently, when it is determined that the operator has scrolled to the target position, the screen is stopped (step S9) by releasing the finger from the screen (interruption of finger touch) (step S8). Step S
11 erases the scroll display screen.

If it is determined in step S4 that the arrow of group B has been touched, it is determined which of the arrows B1 to B8 of group B has been touched (step S6).
A scroll operation is performed in the direction of the finger touch arrow to move the map display (step S7). Then, even when the operator releases the finger from the screen (step S8), the intermittent operation of the screen scroll is executed (step S10), and when the operator determines that the scroll has been performed to the target position,
The touch operation on the screen is performed again, and it is determined again whether the touch (finger touch) operation on the screen is an arrow of the group A or other (step S12). Here, if it is determined that a finger other than the arrow in the group A is being touched, the operation shifts to the operation of step S9 to stop the screen scrolling operation. Further, when it is determined that the group A arrow is touched, the process returns to step S5,
It is determined which of the arrows A1 to A8 of the group A has been touched.

Next, another embodiment of the present invention will be described.
In the present embodiment, when a map or a cursor is moved by scrolling, when the cursor exceeds a predetermined area on the display screen, the operator is notified of the fact by voice or on the screen. In particular, the map screen displayed on the monitor screen in the above embodiment is enlarged (zoomed).
When displaying, the above-mentioned area is set in advance according to the zoom ratio.

For example, if each of the zooms 1, 2 and 3 having different zoom rates has the maximum magnification, the medium enlargement magnification and the small screen, the above-mentioned area at the time of scrolling with the zoom 1 is divided into "divisions" and the scrolling with the zoom 2 is used. The above area at the time is a unit of “city”, and the above area at the time of scrolling with zoom 3 is “prefecture”.
Is notified by voice or the like so that the operator can know the approximate scroll position. More specifically, when the above-described intermittent scroll is executed with zoom 3, when the center point enters Kanagawa prefecture from Tokyo, and when the center point enters Kanagawa prefecture from Tokyo, the voice guidance indicates “ I have entered Kanagawa Prefecture. "

In the above embodiment, the scroll instruction is executed by operating the touch panel switch. However, a push switch, a joystick or the like can be used instead of the touch panel switch. When a joystick is used, eight directions can be operated. For example, normal scrolling is performed by inputting once in the right direction, and intermittent scrolling is performed by inputting it twice within a predetermined time.

Also, in the touch operation, eight A groups,
The functions of the scroll direction, normal scroll, and intermittent scroll are allocated by touching each of the eight B groups, that is, a total of 16 B groups. The function can be realized only by the eight directional arrows of the A group. In other words, if you touch only the direction arrow,
Normal scrolling and intermittent scrolling can be used separately when two fingers simultaneously touch the center and direction arrow with two fingers.

Although the preferred embodiment of the navigation system according to the present invention has been described above, this is merely an example, and it is a matter of course that various modifications can be made in accordance with a specific application.

[0039]

As described above, in the navigation system according to the present invention, not only the normal scroll operation but also the intermittent scroll is continued even if the normal scroll stop operation is performed, so that the scroll operation is performed. The burden on the middle operator is reduced, and the effect becomes greater as the search position is farther. In addition, a special effect is obtained that it is possible to prevent excessive scrolling due to slowness of the operator's attention during execution of intermittent scrolling of the map screen displayed on the monitor screen.
