Novel Tap Operation on Capacitive Touch Screen for People with Visual Impairment

Abstract

We propose a novel tap method for a capacitive touch screen, which is called inverse tap (iTap). Because this is operated as follows: a finger is removed from a screen first, and then put on it, different from normal tap. It enables the people with visual impairment to find a braille on a touch screen and operate a button, after remembering a button and a function layout. It also enables drivers to operate a car audio and an A/C through a touch screen instrument panel after a quick look at it while driving when they can not close watch on it.
