Multiple texture button by adding haptic vibration and displacement sensing to the physical button

Abstract

A physical button that is mounted in a mouse, a keyboard, or a shutter of a camera, provides both force and tactile feedback when a user presses it. It is certainly that users can recognize the press and input through the sensation of vibrations. Many mechanical mechanisms for presenting a click sensation in a physical button have been proposed, however the click sensation can be generally presented in only one for one physical button. On the other hand, the virtual button on a touchscreen lacks haptic feedback such as a click sensation because there is no mechanical mechanism. To solve these issues, approach to reproduce and present a click sensation has been proposed by presenting the haptic vibration for the press of the virtual buttons [Fukumoto et al., 2001][Tashiro et at., 2009][Kim et at., 2013].
