Novel Projection Methods   Chair: Tom Appollini , Harris Corporation   Oblique Projector Rendering onto Planar Surfaces for a Tracked User   When projectors create keystoning, a traditional graphics pipeline with a modified projection matrix and an approximation of the z-buffer can be used to create perspectively correct images for a tracked moving user in CAVE or ImmersaDesk.   Ramesh Raskar University of North Carolina Chapel Hill Sitterson Hall, CB3175 Chapel Hill, North Carolina 27599 USA raskar@cs.unc.edu   Projecting Computer Graphics on Moving Surfaces: A Simple Calibration and Tracking Method   A simple method of calibrating a camera and a projector so the projected image exactly matches the surface of a moving object. The method is used in the HyperMask system that projects faces on a mask worn by an actor during a performance.   Claudio Pinhanez Massachusetts Institute of Technology 20 Ames Street, Room E15-368C Cambridge, Massachusetts 02139 USA pinhanez@media.mit.edu   Head-Mounted Projector   A head-mounted projector that uses X'tal Vision (Crystal Vision) technology, a projection-based augmented-reality system composed of a projector with a small iris and a retroreflective screen.   Masahiko Inami The University of Tokyo Tachi Lab MEIP School of Engineering 7-3-1 Hongo, Bunkyo-ku Tokyo 113-8656 JAPAN media3@star.t.u-tokyo.ac.jp
