3D Touch Surface for Interactive Pseudo‐Holographic Displays

Abstract

Herein, the design and implementation of a transparent 3D touch-enabled surface for richer user interaction with midair 3D virtual objects in a touch-interactive pseudo-holographic display are presented. Frustrated total internal reflection (FTIR)-based touch sensing is used in combination with a four-sided pyramidal pseudo-holographic projection. The developed system allows gesture-based control and smooth touch interaction through facile and inexpensive hardware and open-source software tools. A software application is also developed as the interface between the touch/gesture-sensing system and the optical display. By bringing the virtual and real world closer through touch-based interaction, the presented system will enrich user experience and enable advances in areas such as education, entertainment, gaming, retail, and museums where holograms are currently used.
