"Space Labeling Projectors for High Speed Motion Capture and Rapid Prototyping Using a 3D Printer"
Jay Summet, College of Computing

This talk will introduce work done at Intel Research (Pittsburgh), Carnegie Mellon University (CMU) and Mitsubishi Electric Research Laboratories (MERL). We have built several hardware based tags that are able to locate themselves within a space with the assistance of a projected data pattern. These tags can be embedded in display surfaces, allowing projection surfaces to be moved dynamically. Additionally, they can be used to capture human motion for applications in medical diagnosis, motion capture, and special effects.

This talk will specifically focus on the development of custom solid state projectors which can project 10,000 images a second in the infrared (IR) spectrum, allowing for invisible and extremely high speed (500Hz) sampling in outdoor lighting conditions.

The manufacture of these custom projectors was greatly eased by the use of a rapid prototyping machine (3D printer), similar to the one that the GVU has recently acquired. At the end of the talk, I will give an overview of the 3D printer, and how it can be used to turbo-charge your own research agenda.

Jay Summet is a Ph.D. student at the Georgia Institute of Technology where his thesis work involves projector-camera systems to enable ubiquitous projected displays. His research interests involve user evaluation, mobile computing, and projection systems. He received a M.S. degree from Oregon State University specializing in end-user programming where he was supported by a N.A.S.A. Space Grant.
