Abstract

In this paper, we develop a layered 3D touch screen using capacitance measurement to detect an object both before and after contact for operation of a 3D image on the display. The proposed 3D touch screen employs layered parallel and plane-type capacitance sensors. The 3D touch screen can detect indentations and the precise position of an object and can identify the material in contact with it. In addition, it can detect the object and its position during noncontact (proximity range). Thus, the proposed 3D touch screen detects objects in the 3D range. In this paper, the proposed 3D touch screen is set on a display and detects objects and their positions before and after contact. The proposed 3D touch screen has the potential to be used as functional and useful interface.
