Touch Interactive 3D Surfaces

Abstract

This paper presents the design and implementation of a touch interactive 3D surface using frustrated total internal reflection (FTIR). Using a simple and scalable approach, the touch sensing is enabled all around a transparent acrylic pyramid surface. The developed system steers away from the conventional flat touch surfaces thus enabling touch-based control of applications such as volumetric holographic displays. The potential of presented system also lies in gesture-based control of holographic displays.
