Spatial Augmented Reality-Based, Tangible CAD System

In current computer-aided design (CAD) systems, designers are commonly restricted to a traditional workstation environment with a mouse and keyboard. Researchers from South Korea's Hong-ik University and the University of South Australia submitted this demonstration to 2012's ACM Symposium on Virtual Reality Software and Technology (VRST), an international forum for researchers and developers concerned with virtual reality software and technology. The research team demonstrated a spatial augmented reality (SAR)-based CAD system that consists of a fixed camera-projector pair, a light-emitting diode (LED) pen with two buttons, a wireless communication module, and a physical drawing board.
