Abstract

PURPOSE:To reduce mis-input by an operator by predicting an operator's touch right before the finger, etc., of the operator touch a button, etc., previously displaying the position going to be touched, and feeding it back. CONSTITUTION:When the finger 5 interrupts the optical axis of a touch panel 1, pieces of passage coordinate information x1, y1 are detected and a control part issues an instruction for decreasing the brightness of the display area corresponding to the coordinates to a CRT display 3. In response to the instruction, the brightness of the numerical button parts corresponding to the coordinates x1 and y1 is decreased. Further, when the finger 5 depresses the transparent cover 180 of a touch panel 2, the touch panel 2 detects pieces of contact coordinate information x1', y1' and the control part issues an instruction for temporarily changing the display color of the display area corresponding to the coordinates into another color to the CRT display 3. When the finger 5 is released from the touch panels 1 and 2 thereafter, the CRT display 3 returns the display color of the numerical button part corresponding to the coordinates to the original display color and displays the button number in an input display area 190.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an input support system and, more particularly, to a key input support system for information equipment and the like using a touch panel.

[0002]

2. Description of the Related Art Conventionally, as this type of technology, for example,
The technique disclosed in Japanese Patent Laid-Open No. 60-232707 is known. When this technology detects that the operator's finger touches the display screen, the display color of the button etc. at the position touched by the operator is changed to another display color for a certain period, and then the original display color is changed. The position of the input button or the like is fed back to the operator by returning to.

[0003]

In the above prior art, it is impossible to recognize what button the user is trying to input until the color of the displayed button changes, and the display color changes. Sometimes it is after the input has already been made, so the operation was often redone due to an incorrect input. Especially, when the position of the operator's point of view is changed and the position at which the operator actually touches is slightly deviated from the position at which the button or the like is displayed, this erroneous input frequently occurs. The present invention has been made in view of the above circumstances, and an object of the present invention is to solve the above-mentioned problems in the related art, and to change the touch position immediately before the operator's finger or the like actually touches the display screen. Another object of the present invention is to provide an input support method capable of reducing erroneous input by the operator by displaying it in advance and feeding it back to the operator.

[0004]

The above object of the present invention is to provide an input device equipped with a screen display means for displaying a button or the like for allowing an operator to make an input by touching the same finger or the like. Is provided with a means for detecting just before touching the button or the like with a finger or the like, and the detecting means detects the position to be touched by the operator,
This is achieved by an input support system characterized by displaying the position on the screen display means.

[0005]

In the input support system according to the present invention, the operator intends to touch the detection means described above (expected).
Since the position is detected and the position is displayed on the screen display means, the operator touches the display screen while being surely aware of the position to be touched. After the operator detects the actual touched position and recognizes the input content, the content is displayed on the display screen, so that the operator should finally confirm the input content. Therefore, these actions can reduce erroneous input by the operator.
