Time Threshold for Classification between 2D-Touch and 3D-Touch Based on User’s 3D-Touch Input

Abstract

As 3D-Touch technology has recently developed, 3D-Touch technology, which was applied only to the touch display of mobile devices, has been introduced to various devices. Although many researches have proposed applying the 3D-Touch technology to various devices, these researches have been confined only to apply 3D-Touch technology without considering 2D-Touch technology. Therefore, there is no clear criterion for distinguishing between 2D-Touch and 3D-Touch. In this paper, we suggest a time threshold for distinguishing between 2D-Touch and 3D-Touch on a display that supports 3D-Touch.
