PDRIVE: the projector-based, desktop, reach-in virtual environment

This paper presents the Projector-based, Desktop, Reach-In Virtual Environment, or PDRIVE. A PDRIVE user "reaches in" to the virtual environment, which he views through a mirror. Stereo images are generated by two standard, off-the-shelf DLP projectors, which provides a large display and workspace volume at a relatively low cost. Current prototypes use linear polarization for stereo separation and electromagnetically tracked devices for interaction. The PDRIVE is designed to be easy to set up and configure to suit the user's needs, and a variety of projectors, tracking methods, interaction devices, and stereo separation methods can be used in the system.
