Abstract

PURPOSE:To decide the rough time needed for a cursor to move between two spots on a map shown on a display device and also to decide the moving speed of the cursor on the display device. CONSTITUTION:A cursor 110 has the scales et the positions where the flexible length set at a reference point 120 is equally deviced into 10 parts by the actual distances. Then the cursor 110 is displayed on the shortest path based on the drawing. Furthermore, the distance 140 of a single scale and the direction 130 are shown at the positions near the point 120. Then, the cursor 110 expands or contracts according to the movement of a mouse or a track ball, etc., and the display of the distance 140 and the direction 130 are updated in real time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a map display system, and more particularly to a cursor display system capable of confirming the distance between two points, the azimuth and the distance obtained by equally dividing two points at once.

[0002]

2. Description of the Related Art Conventionally, in a system for displaying a map on a display device and designating a distance between two points on the map with a cursor, the system shown in FIG. First, the operator selects the reference point 121 of the cursor.
Is specified by a mouse, a trackball, etc., and thereafter, a reference point 121
A flexible cursor is displayed in accordance with the projection method, and the distance of the displayed cursor on the map 141,
The azimuth 131 is displayed near the reference point 121.

In this way, by moving the mouse, the trackball or the like, the cursor is displayed from the reference point 121 in accordance with the drawing method, and the distance 141 to the end of the cursor is displayed.
And the direction 131 are displayed in real time.

[0004]

Conventionally, as described above, since the distance and direction from the reference point to the end of the cursor are displayed in real time, only the distance between the two points can be confirmed, and the distance between the two points can be confirmed. There is a drawback that the approximate time required for moving and the moving speed cannot be determined on the screen.

[0005]

[Means for Solving the Problems] By displaying a map on a display device and designating two points on the map with a cursor,
In the system that automatically displays the distance and direction between two points,
An expandable and contractible cursor is displayed on the map according to the movement of the mouse, trackball, etc. from the reference point so that it becomes the shortest route according to the drawing method, and the distance between the two points is preset on the route (cursor). It is characterized in that a scale is provided at a position divided into two and the distance and direction of one scale are displayed near the reference point.

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention.
The display unit 100, the data processing unit 101, the keyboard unit 102, the mouse / trackball unit 103, and the display screen 104 of the display unit 100 are included.

FIG. 2 is a diagram of an embodiment of the present invention, in which a map, a cursor 110, a direction 130 and a distance 140 are displayed on the display screen 104. The operation of this embodiment will be described with reference to the drawings below. explain.

As a first example, a certain point (reference point 12
When it is desired to know the time required to move from 0) to the target point (target point), first, the reference point 120 is designated by a mouse or a trackball. After that, the cursor 11 which is expandable and contractable from the reference point 120 according to the movement of the mouse or the trackball and has a scale at a position where the length is 10 equal to the actual distance is displayed in accordance with the drawing method so as to have the shortest distance, Further, the distance 140 and the azimuth 130 of one scale are displayed near the reference point 120. At this time, if the cursor 110 extending from the reference point 120 passes over a target point (target point) and the value of the distance 140 on one scale is the same as the speed of moving from the reference point 120 to the target point. Since one scale is the speed per unit time and the moving distance, the time required to move to the target point in the shortest distance can be known by reading the position of the target point with the scale of the cursor 110.

As a second example, when it is desired to know the speed required to move from the reference point 120 to the target point, the cursor 110 is displayed so as to be the shortest route according to the drawing method as in the first example. Further, the distance 140 and the azimuth 130 of one scale are displayed near the reference point 120. At this time, the cursor 110 extending from the reference point 120 passes over the target point, and the scale on the cursor 110 requires the time required to move to the target point in the shortest distance (for example, if it is necessary to move to the target point in 8 hours). (8th scale), one scale is the moving distance per unit time and is the speed, so it is necessary to read the distance 140 of one scale to move to the target point in the shortest distance. I know the speed.

As a third example, when it is desired to know the movement distance and the arrival point for each unit time when traveling in a certain direction from the reference point 120, the direction 130 and the distance 140 can be adjusted to the desired direction and unit time. Since the arrival point for each unit time is the position of each scale of the cursor 110,
The arrival point per unit time can be known from the position of the scale of the cursor 110.

[0012]

As described above, according to the present invention, on a map displayed on a screen, a cursor having a scale at a position where the shortest route between two points and the distance on the route is divided into 10 equal parts, and By displaying the distance and direction of one scale by numerical values and reading the scale or the numerical values, it is possible to know the approximate time and moving speed required to move between arbitrary points.
