<p>PURPOSE:To enable even a person who has weak eyesight to operate an automatic machine, etc., by providing a matrix type heat generation part on the touch panel and composing brailles of a heat generation pattern. CONSTITUTION:Heat generation bodies 3 are arranged at intersections on the surface of the optical touch panel 1 matching the size of the screen of a display 2. The heat generation bodies 3 are supplied with a current from transparent electrodes arranged in matrix to generate heat enough to selectively feel the individual heat generation bodies 2. The heat is utilized to characters or equivalent braille such as characters or icons showing a touch area displayed on the screen of the display 2. In this case, an operator touches the touch panel 1 with plural fingers to read the braille selects an item part to be selected with the braille, and touches only the item part to be selected again, so that the optical touch panel 1 outputs its coordinates for the 1st time.</p> |
