Abstract
PCs and cell phones have physical buttons such as a keyboard and call buttons, but a touch screen device usually does not. Since there are no tactile marks such as braille, it is difficult to operate through a capacitive touch screen without seeing and just after a quick look at the screen. We have proposed a new operation method called inverse tap (iTap) for capacitive touch panels [1]. iTap is judged as a tap operation when the finger leaves the screen and touches it again. User can find the point of operation by the tactile marks without looking at the screen, and perform operation equivalent to tapping. In this paper, we propose a new additional method called “two-finger inverse tap”, and attempt to diversify the operation options for a single operation point.
