Abstract

PURPOSE:To allow the movement of a cursor to angles in addition to a diagonal direction and to allow the adjustment of the cursor moving speed as well as to decrease the man-hours for data input by adding a cursor moving key. CONSTITUTION:The key 2 which facilitates the movement of the cursor in a diagonal direction is added to a keyboard 1. The cursor moves in the direction corresponding to the pushed direction when the cursor moving key 2 on the keyboard 1 is pushed in the case of moving the cursor in the diagonal direction on the screen of a display device. The moving speed of the cursor is changed by the pushed pressure at this time. The moving speed increases when the key is pushed strongly and the moving speed decreases when the key is weakly pushed. The cursor can be moved even to the angles in addition to the diagonal direction and the varying of the cursor moving speed is possible. The man-hours for the data inputting are thus decreased.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cursor control device and a cursor control method in display devices and keyboards used in electronic computer systems and the like.

[Conventional technology]

The conventional cursor control method is disclosed in Japanese Patent Application Laid-Open No. 61-235893.
As described in the above publication, the cursor can only be moved diagonally at 45 degrees.

[Problem to be solved by the invention]

The above-mentioned conventional technology does not consider directions other than 45 degrees diagonally for cursor movement, and has the problem that the cursor movement speed cannot be adjusted.

An object of the present invention is to enable cursor movement at angles other than the 45-degree diagonal direction, to make the cursor movement speed adjustable, and to reduce the number of data inputs.

[Means to solve the problem]

In order to achieve the above purpose, a cursor movement key is added.

[Effect]

To move the cursor diagonally on the screen of a display device, press the cursor movement key on the keyboard.
The cursor moves in the direction corresponding to the pressed position. At this time, the moving speed of the cursor changes depending on the pressure applied. That is, if you press it hard, the movement speed will increase, and if you press it weakly, it will slow down.

As a result, the cursor can be moved at an angle other than 45 degrees, and the cursor movement speed can be varied.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3, 4, and 5.

Cursor position in Figure 4! ! 7 to cursor position IE8 or 9
To move the cursor to , press the cursor movement key 2 on the keyboard 1 in Figure 1 to move the cursor to key switch 3 and key switch 4.
At this time, if two or more of the key switches 3 touch, the μ controller 12 calculates and determines the intermediate point, and issues a cursor movement angle instruction to the control circuit 11.
The cursor position is displayed on the display device 14 via the drive circuit 13.

As for the cursor movement speed, when the cursor movement key 2 is pressed down, the pressure sensor 6 is pressed in accordance with the pressing pressure and generates a voltage. The μ controller 12 calculates this.

If the pressure is strong, the cursor moves quickly; if the pressure is weak, the cursor moves slowly.

[Effects of the Invention] According to the present invention, the cursor can be moved in any direction and at any speed on the screen of the display device using the cursor movement keys on the keyboard, so there is an effect that the number of data inputs can be reduced.
