VASC Seminar Announcement ========================= Date: Monday, March 11 Time: 3:30-4:40 Place: NSH 1507 Title: Tele-Graffiti: A Remote Sketching System Speaker: Naoya Takao Abstract: Many ideas are best communicated by drawing simple sketches. If the two people are located remotely from each other, a "remote sketching system" can help them communicate better. The first such camera-projector based remote sketching system was Paul Wellner's Xerox DoubleDigitalDesk. We recently developed Tele-Graffiti, a remote sketching system which provides solutions for the problems none of which was provided by the previous works. Its advantages include: (1) real-time paper tracking to allow users to move the paper, (2) hand-based user interface, and (3) feedback control to maximize the quality of shared images based on analysis of camera-projector systems. In this talk, I will describe the design and implementation of Tele-Graffiti, including paper tracking, hand-based user interface and feedback analysis.
