BACKGROUND OF THE INVENTION
The present invention relates to a user by displaying a map on a screen of a display device such as a liquid crystal display to the map display equipment that provides map information.
[0002]
[Prior art]
Conventionally, this type of map display device is used in a navigation device that guides and guides a user to a destination, which detects a current position using a GPS (Global Positioning System) receiver or the like, and also uses a DVD- By displaying the map screen on the liquid crystal display based on the map data read from the ROM or the like, and displaying the current position on the displayed map screen, it is possible to present to the user which side the user is currently on. In-vehicle devices are the most widespread of such navigation devices, but with the development of communication technology, portable devices that download map data from external servers, or fixed devices installed in drive-ins, etc. There are also things.
[0003]
In the case of an in-vehicle navigation system, when a destination is entered, a recommended route from the current location to the destination is searched, and the route is displayed on the road on the monitor screen. You can go in a short time. On the liquid crystal display, the current position of the vehicle and the searched guidance route are displayed. By changing the scale, a destination at a long distance can be displayed on the same screen as the current position. In addition, a desired place can be displayed by scrolling the map screen with a scroll key or a touch sensor panel.
[0004]
As a scroll method using a conventional touch sensor panel, there is a method of pressing (touching) an arrow key displayed on a screen and scrolling in that direction. There is also a method of dividing the screen into a plurality of areas radially from the center and scrolling the screen in the direction of the area pressed by the finger. Further, there is a one-touch scrolling method in which the position pressed on the screen is moved to the center of the screen.
[0005]
[Problems to be solved by the invention]
However, in the conventional scrolling method using the touch sensor panel, the distance to be moved by one touch is determined by the method of pressing the arrow key displayed on the screen or the method of scrolling in the direction pressed by the finger. Therefore, in order to display the target location, it may be necessary to touch several times, and there is a problem that operation time is required. Also, the one-touch scrolling method of moving the pressed position on the screen to the center of the screen has to touch the screen many times in order to display the position not displayed on the screen.
[0006]
The present invention solves such a conventional problem. The map can be moved to a desired position without touching the screen a plurality of times, the operation time is short, and the continuous scroll feeling is achieved. and to provide a MAP display device using a touch sensor panel is located, and can be scrolled in any direction.
[0011]

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is a block diagram showing a schematic configuration of a map display device according to an embodiment of the present invention. A touch sensor panel 2 in which touch sensors are arranged in a matrix is placed on the front surface of the liquid crystal display 1 that displays a map and related information. When the touch sensor panel 2 is pressed with a finger, the coordinate position is detected by the coordinate detection unit 3. The control unit 4 composed of a microcomputer converts the map data read by the map data reading unit 5 such as a DVD-ROM drive into drawing data and displays it on the screen of the liquid crystal display 1, and a position signal from the coordinate detection unit 3. The screen of the liquid crystal display 1 is scrolled based on the above. The storage unit 6 stores a table indicating the scrolling direction and speed, and the control unit 4 performs scrolling with reference to this table.
[0018]
FIG. 2 shows scroll processing in the present embodiment. First, a map is displayed on the screen of the liquid crystal display 1 (step S1), and a position to be scrolled on the displayed map is touched with a finger via the touch sensor panel 2 (step S2). ) Is scrolled to a predetermined position on the screen of the liquid crystal display 1 (step S3). As shown in FIG. 3, in this one-touch scroll, when the touch position Pt at the upper right corner is touched on the screen A before touching the liquid crystal display 1, for example, the coordinate position of the touch position Pt is detected by the coordinate detection unit 3, and the touch The map moves to a screen B after touching so that the position Pt matches the center cursor position Pc that is the center of the screen. In FIG. 3, in order to express the relative movement between the map and the screen in an easy-to-understand manner, the map is fixed and the screen is moved. Further, the internal processing of the control unit 4 is realized by performing processing for moving the display range on the large map in the direction of the pressed position. After the one-touch scroll, it is checked whether or not the touch continues as it is for a predetermined time or more (step S4). If the touch is not touched, it is determined that the user desires only the one-touch scroll and the scroll process is ended. If the touch continues (if the touch position deviates from the one-touch scroll position, the touch only needs to be continued), the center cursor changes its shape and informs that it will shift to continuous scrolling (step S5) Continuous scrolling is performed in the currently touched direction (step S6), and when the touch is finished, the continuous scrolling is terminated (step S7). The determination of the duration time in step S4 may be made so that the one-touch scrolling and the continuous scrolling are switched at a predetermined time by measuring from the time when the screen is first touched and after a predetermined time has elapsed. When the scroll is scrolled at a constant speed, the processing end time also varies depending on the distance between the touch position Pt and the center cursor position Pc. Therefore, a predetermined time may elapse after the end of the one-touch scroll processing. Further, the shape change of the center cursor in step S5 may be performed by changing at least one of the shape, color, and size, or displaying a new mark, or may not be changed.
[0019]
In the case of FIG. 3, the continuous scrolling is to continuously scroll the map from the touch position Pt to the center cursor position Pc in the center of the screen on the screen A before the touch. Which direction of scrolling is determined in advance depending on the touched position. FIG. 4 is a diagram for explaining the scroll direction. As shown in FIG. 4A, the screen area C corresponding to the display screen is divided into 20 areas a1 to a20 radially from the screen center O, and each area includes ), The area range and the scroll direction of the map are set (the right direction of the X axis is 0 °, and the counterclockwise direction is positive). Accordingly, after calculating which area the position is included in based on the detected touch position coordinates, the scroll direction is determined. In the case of the touch position Pt in FIG. 3, since it is included in the area a2, the map is continuously scrolled in the direction of 210 degrees.
[0020]
The screen area C is further divided into four rectangular zones z1 to z4 concentrically with the screen center O as the base point, as shown in FIG. And in each zone, as shown in FIG.5 (b), the scroll speed (unit dot / s) is prescribed | regulated by the relationship with elapsed time (second). That is, for each zone, an initial speed Va from the start of continuous scrolling to 0.6 seconds, a medium speed Vb after 0.6 seconds, and a fastest speed Vc after 1.6 seconds are determined. FIG. 6 shows the speed change in each zone when the zones z3 and z4 are defined at the same speed. These numerical values can be set arbitrarily, but in the case of scroll speed, the outermost zone z4 (far from the center) is faster than the center z1 of the screen. Desirable because it can. In this case, the scroll speed from the zones z1 to z3 may be the same, and the scroll speed from the zones z2 to z4 may be the same. In particular, in the zone z1 at the center of the screen, it is considered that the user desires fine adjustment of the display. Therefore, by sufficiently slowing down the scrolling speed, the movement of the map display position can be suppressed as much as possible. It should be possible. Further, the scroll speed may be changed according to the scale of the map to be displayed. In this case, fine adjustments are desired for narrow-area maps such as urban areas, and conversely, for wide-area maps of 1 / 160,000 or more, rough movement is often desired as preprocessing to display more detailed maps. Scrolling too fast makes it difficult to adjust as desired.
[0021]
Thus, according to this embodiment, when continuous scrolling is started, the scroll direction is determined according to the area of the touched position, and the zone at the touched position and the elapsed time from the start of continuous scrolling are determined. The scrolling speed changes according to. Furthermore, by changing the scrolling speed according to each zone, continuous scrolling is performed, and the peripheral part of the screen is farther from the center, so when the peripheral part is pressed, the scrolling speed is compared with the center side. If the user presses for a short time, the scrolling speed is slowed down, and the scrolling speed is increased as the pressing time becomes longer. You can scroll to the location.
[0022]
In the present embodiment, if the touched position is moved to another position while being continuously touched during continuous scrolling, the map can be continuously scrolled from the different position toward the center of the screen. For example, the touched position is a position in the direction 90 ° directly above the center of the screen (the position of the area a5 or a6 in FIG. 4), and the map is continuously scrolled in the downward direction to the upper right 45 ° (in FIG. 4). When the touched position is moved so that the finger is traced in the direction of the area (a3 position), the direction of continuous scrolling gradually changes from the directly lower direction to the lower left 45 ° (position of the area a13 in FIG. 4) direction. If the finger is moved 180 degrees around the center of the screen while continuously scrolling downward, the direction of continuous scrolling will change from moving directly downward to moving upward. It becomes.
[0023]
In addition, the scroll method described in the present embodiment can be used when the display screen is divided into left and right parts to display a map image on one side, or when a three-dimensional map image is displayed. The same applies. In particular, when continuous scrolling is performed when a three-dimensional map image is displayed, as shown in FIG. 7, scrolling is performed in the direction projected on the two-dimensional map image, thereby performing calculation processing related to scrolling. It is desirable to reduce.
[0024]
(Embodiment 2)
Next, a second embodiment of the present invention will be described. The second embodiment is a process when the guide function is set in the scroll process in the first embodiment. The guide function is a process of matching the landmark, not the touched position, with the center of the display screen when the landmark is displayed near the touched position. In FIG. 8, a map is first displayed on the screen of the liquid crystal display 1 (step S11), and a position to be scrolled on the displayed map is touched with a finger via the touch sensor panel 2 (step S12). Next, it is checked whether or not there is a display indicating that the guide target point is displayed on the screen (step S13). If there is no display, the one-touch scroll and the continuous scroll similar to those shown in FIG. I do. If there is a guide target point displayed in step S13, it is checked whether there is a guide target point in the vicinity of the touched position (step S19). One-touch scrolling is performed so that the center cursor position matches the position of the guide target point (step S20). After this one-touch scrolling, it is checked whether or not the touch continues for a predetermined time or longer (step S21). If the touch is not touched, the user desires a guide display. This is performed (step S22). If the touch is continued, it means that the user desires continuous scrolling, and therefore, the process proceeds to the continuous scroll process after step S16.
[0025]
As described above, according to the second embodiment, when the apparatus has a guide function and there is a guide target point on the displayed map screen, the guide display is performed by one-touch scrolling to the guide target point. Can do.
[0026]
【The invention's effect】
As described above, in the present invention, when the map displayed on the display screen is scrolled by pressing the touch sensor panel arranged in front of the map, the pressed position of the touch sensor panel is set at the center of the display screen. The map is scrolled one-touch so that the map is continuously scrolled from the pressed position to the center of the display screen (predetermined position) until the pressing is released. One-touch scrolling that can be executed regardless of the duration of the initial setting is used as an initial setting, and only one-touch scrolling can be used, and two types of usage can be used, that is, continuous transition to continuous scrolling. Even if you do not just scroll the map in the same direction, It is possible to move the short operation time, there is a continuous scrolling feeling, and can be scrolled in any direction.
