We have developed and deployed a multimedia museum installation that enables one or several users to interact with and collaboratively explore a 3D virtual environment while simultaneously providing an engaging and educational, theater-like experience for a larger crowd of passive viewers. This interactive theater experience consists of a large, immersive projection display, a touch screen display for gross navigation and three wireless, motion-sensing, hand-held controllers which allow multiple users to collaboratively explore a photorealistic virtual environment of Atlanta, Georgia and learn about Atlanta's history and the philanthropic legacy of many of Atlanta's prominent citizens.
