Hybrid Infrared and Visible Light Projection for Location Tracking (2007)
Proceedings of the ACM Symposium on User Interface Software and Technology
Interactive projection systems typically require a dedicated location tracking technology for the purposes of cursor or controller input. Many research systems exploring projector-based augmented reality and augmented worktables require accurate registration of the projected imagery onto physical surfaces which is done either manually, using a camera, or other tracking device. In this paper, we describe the implementation of a prototype projector capable of displaying both infrared as well as visible light images. Using infrared patterns, we can discover the locations of light sensors in a manner that is invisible to a human observer while visible patterns provide application content. By unifying the location tracking and projection technology into a single device, we can greatly simplify the implementation and execution of interactive projection systems and inherently support multi-user stylus input on surfaces that may be non-planar and discontinuous.
