Character interaction with handheld projectors

I present a summary of my research dealing with character interaction using handheld projectors. My work draws from the tradition of pre-cinema handheld projectors that use direct physical manipulation to control projected imagery. I build upon this work with a system allowing users to interactively control characters by moving and gesturing with the handheld projector itself. This creates a unified interaction style where input and output are tied together within a single device. I present a prototype handheld platform, several games, and augmented reality application scenarios to illustrate the approach.
