We present a system for dynamic projection on large, human-scale,
moving projection screens and demonstrate this system for immersive
visualization applications in several fields. We have designed and
implemented efficient, low-cost methods for robust tracking of
projection surfaces, and a method to provide high frame rate output for
computationally-intensive, low frame rate applications. We
present a distributed rendering environment which allows many
projectors to work together to illuminate the projection surfaces.
This physically immersive visualization environment promotes
innovation and creativity in design and analysis applications and
facilitates exploration of alternative visualization styles and modes.
The system provides for multiple participants to interact in a shared
environment in a natural manner. Our new human-scale user interface
is intuitive and novice users require essentially no instruction to
operate the visualization.
