Towards a handheld stereo projector system for viewing and interacting in virtual worlds

We present a proof-of-concept implementation of a handheld stereo projection display system for virtual worlds. We utilize a single pico projector coupled with a six DOF tracker to generate real-time stereo imagery that can be projected on walls or a projection screen.We discuss the iterative design of our display system, including three attempts at modifying our portable projector to produce stereo imagery, and the hardware and software tradeoff decisions made in our prototype.
