DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a map display device for displaying a map on a screen of a display device such as a liquid crystal display and providing map information to a user, and a scrolling method for moving the displayed map screen.

[0002]

2. Description of the Related Art Conventionally, this type of map display device has been used for a navigation device for guiding a user to a destination, which is a GPS (Global Positioning System).
m) While detecting the current position using a receiver, etc.,
A map screen is displayed on a liquid crystal display based on map data read from a DVD-ROM or the like, and a current position is displayed on the displayed map screen, so that the user can be presented with which side he is currently. it can. Among such navigation devices, in-vehicle devices are the most widespread, but due to the development of communication technology, portable devices that download map data from an external server, and fixed devices that are installed in a drive-in or the like. There are also things.

In the case of an in-vehicle navigation device, when a destination is input, a recommended route from the current position to the destination is searched for, and the route is displayed on a road on a monitor screen, so that the user can go to the destination for the first time. You can go in a short time without hesitation. The current position of the vehicle and the searched guidance route are displayed on the liquid crystal display. By changing the scale, even a destination located far away can be displayed on the same screen as the current position. In addition, a desired location can be displayed by scrolling the map screen using a scroll key or a touch sensor panel.

As a conventional scrolling method using a touch sensor panel, there is a method of pressing (touching) an arrow key displayed on a screen to scroll in that direction. There is also a method of dividing the screen radially from the center into a plurality of areas, and scrolling the screen in the direction of the area pressed by a finger. Further, there is a one-touch scroll method of moving a position pressed on the screen to the center of the screen.

[0005]

However, in the conventional scrolling method using the touch sensor panel, a method of pressing an arrow key displayed on a screen or a method of scrolling in a direction pressed by a finger is one time. Since the moving distance is determined by the touch of the touch panel, the user may have to touch the display many times to display a target place, which causes a problem that an operation time is required. Also,
In the one-touch scroll method of moving the position pressed on the screen to the center of the screen, the user has to touch the screen many times to display a position not displayed on the screen.

The present invention is to solve such a conventional problem, and can move a map to a desired position without touching the screen a plurality of times. It is an object of the present invention to provide a map scrolling method and a map display device using a touch sensor panel that has a natural scroll feeling and can scroll in an arbitrary direction.

[0007]

In order to achieve the above object, a map scrolling method according to the present invention provides a map for moving a map displayed on a display screen by pressing a touch sensor panel disposed on the front of the map. In the scrolling method, the map is one-touch scrolled so that the pressed position of the touch sensor panel becomes a predetermined position on the display screen, and when the pressing is continued as it is, until the pressing is released, It is characterized in that the map is continuously scrolled from the pressed position of the touch sensor panel in the direction of the predetermined position, wherein a frequently used one-touch scroll is used as an initial setting, and only one-touch scroll is used, Two types of usage are possible: one to continue to scroll continuously and the other to continue Yes, even when performing continuous scrolling, the map can be moved in the pressed direction by simply pressing the same position continuously, so the operation time is short, there is a continuous scrolling feeling, and any You can scroll in the direction of.

The map scrolling method according to the present invention is characterized in that a transition is made to the continuous scrolling after a lapse of a predetermined time from the pressing start time for the one-touch scrolling. , And the case of transition to continuous scrolling can be clearly recognized.

Further, the map scroll method of the present invention is characterized in that the control is shifted to the continuous scroll after a predetermined time has passed from the end of the one-touch scroll processing.
It is possible to clearly recognize the case of transition to continuous scrolling.

In the map scroll method according to the present invention, at least one of a shape, a color and a size of a cursor is changed or a new mark is displayed when the one-touch scroll is changed to the continuous scroll. This is a feature, and it is possible to clearly recognize the case where only one-touch scroll is used and the case where transition to continuous scroll is performed.

[0011] Also, a map display device of the present invention provides a display device for displaying a map based on map data, a touch sensor panel disposed on the front of the display device, and a coordinate position where the touch sensor panel is pressed. A coordinate detecting means for detecting the map, and displaying the map on the display device, and displaying the map such that a position where the touch panel sensor is detected by the coordinate detecting means is pressed is a predetermined position on a screen of the display device. One-touch scrolling,
Control means for continuously scrolling the map from the pressed position of the touch sensor panel in the direction of the predetermined position until the pressing is released, if the pressing is continued as it is, With the one-touch scroll, which is frequently used, as an initial setting, there are two usage modes, one using only one-touch scroll, and the case of continuously shifting to continuous scroll. Since the map can be moved in the pressed direction only by continuously pressing the position, the operation time is short, there is a continuous scroll feeling, and scrolling can be performed in any direction.

Further, in the map display device of the present invention, the screen area of the display screen is divided into a plurality of areas radially from the center thereof, and a scroll direction is determined in advance for each area, and the pressed position exists. It is characterized in that the continuous scrolling is performed in a direction determined for the area to be moved, and the map can be moved in the pressed direction by simply pressing the same position continuously.

Further, the map display device of the present invention divides the screen area of the display screen into a plurality of zones from the center to the periphery, determines a scroll speed for each zone in advance, and The continuous scrolling is performed at a speed determined for a zone where a position exists, and the scroll speed can be changed according to the pressed position.

Further, the map display device according to the present invention is characterized in that the scroll speed is set higher in a zone farther from the center of the screen area. Since the moving distance is long, when the peripheral portion is pressed, the scroll speed is increased, so that the user can quickly scroll to a target location.

Further, the map display device of the present invention is characterized in that the scroll speed is changed in accordance with a pressing time, and when performing continuous scrolling,

[0017]

Embodiments of the present invention will be described below 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 superimposed on a front surface of a 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. A control unit 4 including a microcomputer converts map data read by a map data reading unit 5 such as a DVD-ROM drive into drawing data, displays the drawing data on the screen of the liquid crystal display 1, and outputs a position signal from the coordinate detection unit 3. The screen of the liquid crystal display 1 is scrolled based on. The storage unit 6 stores a table indicating the direction and speed of scrolling, and the control unit 4 scrolls by referring to this table.

FIG. 2 shows scroll processing according to 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 of the displayed map is touched with a finger via the touch sensor panel 2 (step S2). ) Is performed to scroll to a position on the screen of the liquid crystal display 1 (step S3). In the one-touch scrolling, as shown in FIG. 3, for example, when the touch position Pt at the upper right corner is touched on the screen A of the liquid crystal display 1 before the touch, the coordinate position of the touch position Pt is detected by the coordinate detecting unit 3, The map moves so that the screen B after the touch is made so that the position Pt matches the center cursor position Pc which is the center of the screen. In FIG. 3, the map is fixed and the screen is moved in order to easily represent the relative movement between the map and the screen. The internal processing of the control unit 4 is realized by performing a process of moving a display range on a large map in the direction of the pressed position. After the one-touch scroll, it is determined whether or not the touch has continued for a predetermined time or more (step S4). If the touch has not been made, the scroll process is terminated, assuming that the user desires only the one-touch scroll. If the touch is continued (even if the touch position is shifted from the position of the one-touch scroll, the touch may be continued), the shape of the center cursor is changed and the transition to the continuous scroll is notified (step S1). S5) Continuous scrolling is performed in the direction currently touched (step S6), and the continuous scrolling ends when the touch is completed (step S7). It should be noted that the determination of the duration in step S4 may be made after a predetermined time elapses from the time when the screen is first touched, so that one-touch scrolling and continuous scrolling can be switched in a predetermined time. When the scroll is scrolled at a constant speed, the processing end time changes depending on the distance between the touch position Pt and the center cursor position Pc. Therefore, the predetermined time may be set after the end of the one-touch scroll processing. Also,
The shape change of the center cursor in step S5 is as follows.
At least one of the shape, color, and size may be changed, or a new mark may be displayed, or may not be changed.

In the case of FIG. 3, the continuous scroll is to continuously scroll the map from the touch position Pt to the center cursor position Pc at the center of the screen on the screen A before the touch. The direction of scrolling according to the touched position is predetermined. FIG. 4 is a diagram for explaining the scroll direction. FIG.
As shown in (a), a screen area C corresponding to the display screen
Is radially divided from the center O of the screen into 20 areas a1 to a20, and in each area, as shown in FIG. 4B, a range of the area and a scroll direction of the map are set. (The right direction of the X axis is 0 ° and the counterclockwise direction is positive.) Therefore, based on the detected touch position coordinates, after calculating which area the position is included in, the scroll direction is determined. In the case of the touch position Pt shown in FIG. 3, since the map is included in the area a2, the map is continuously scrolled in the direction of 210 degrees.

As shown in FIG. 5 (a), the screen area C is concentrically divided into four rectangular zones z1 to z4 starting from the screen center O. Each zone has a scroll speed (unit d) as shown in FIG.
ot / s) is specified in relation to the elapsed time (seconds). That is, for each zone, 0.
Initial speed Va up to 6 seconds, medium speed Vb after 0.6 seconds, 1.
The fastest Vc after 6 seconds is determined. FIG. 6 shows a speed change in each zone when the zones z3 and z4 are defined to have the same speed. These numerical values can be set arbitrarily. In the case of the scroll speed, the outermost zone z4 (farther from the center) is faster than the center z1 at the center of the screen. Desirable to be able to. In this case, the zones z1 to z3
May be the same, or the scroll speeds of the zones z2 to z4 may be the same. Also, especially in the zone z1 at the center of the screen, it is considered that the user wants to fine-adjust the display. Therefore, by making the scroll speed sufficiently low, the amount of movement is suppressed as much as possible to minimize the minute movement of the map display position. It should be possible. The scroll speed may be changed according to the scale of the map to be displayed. In this case, fine-tuning is desired for a narrow area map such as an urban area, and conversely, for a wide area map of 1 / 160,000 or more,
Since rough movement is often desired as a pre-process for displaying a more detailed map, scrolling too fast makes it difficult to make the desired adjustment, so the scroll speed may be reduced.

As described above, according to the present embodiment, when continuous scrolling is started, the direction of scrolling is determined according to the area of the touched position, and the zone of the touched position and the start of the continuous scrolling are started. The scroll speed changes according to the elapsed time. Furthermore, by changing the scroll speed according to each zone,
In addition to performing continuous scrolling, the peripheral part of the screen is farther away from the center, so when the peripheral part is pressed, the scroll speed is increased compared to the center side, and when the pressing is short, the scrolling is performed. By reducing the speed and increasing the scrolling speed as the pressing time increases, scrolling can be performed as desired by the user, and scrolling can be quickly and reliably performed to a desired location.

In the present embodiment, if the touched position is moved to another position while keeping the touched state at the time of continuous scrolling, the map can be continuously scrolled from the other position toward the center of the screen. . For example, the touched position is a position in the direction of 90 ° right above the center of the screen (FIG.
(The position of the area a5 or a6) and the position where the user touches the finger in the direction of the upper right 45 ° (the position of the area a3 in FIG. 4) while continuously scrolling the map directly downward, The direction of the continuous scroll gradually changes from a position directly below to a direction of 45 ° to the lower left (the position of the area a13 in FIG. 4). If you move your finger 180 ° around the center of the screen while continuously scrolling downward, the direction of continuous scrolling changes from moving downward to moving directly upward. Becomes

The scrolling method described in the present embodiment can be applied to a case where the display screen is divided into two parts on the left and right and a map image is displayed on one side, and a case where a three-dimensional map image is displayed. The same can be applied to the above. In particular, when performing continuous scrolling while the three-dimensional map image is displayed, as shown in FIG. 7, by scrolling the touched direction in the direction projected on the two-dimensional map image, the arithmetic processing for scrolling can be performed. It is desirable to reduce it.

(Embodiment 2) Next, Embodiment 2 of the present invention will be described. The second embodiment is a process when a guide function is set in the scroll process in the first embodiment. The guide function is a process of, when a landmark is displayed near a touched position, matching the landmark to the center of the display screen instead of the touched position. 8, first, a map is displayed on the screen of the liquid crystal display 1 (step S1).
1) Touch a position on the displayed map to be scrolled 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 not, then in steps S14 to S18, the same one-touch scrolling and continuous scrolling as shown in FIG. I do. If there is a display of a guide target point in step S13, it is checked whether there is a guide target point near the touched position (step S19). If not, the same processing as described above is performed. 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 determined whether or not the touch has been continued for a predetermined time or more (step S21). Perform (Step S22). If the touch is continued, it means that the user desires continuous scrolling, and therefore, the process shifts to the continuous scrolling process from step S16.

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, one-touch scrolling is performed on the guide target point to display the guide. It can be performed.

[0026]

As described above, according to 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 changed. One-touch scrolling of the map so that it becomes the center of the display screen, and if the pressing is continued, the display screen center (predetermined position) from the pressed position until the pressing is released
Since the map is continuously scrolled in the direction, one-touch scrolling, which can be executed regardless of the duration of pressing, is used as the initial setting. The form is possible, and even when performing continuous scrolling, not only the map can be scrolled in the same direction but also the map can be moved in the pressed direction, so the operation time is short and continuous scrolling is possible. It has a feeling and can be scrolled in any direction.
