DigiTable: an interactive multiuser table for collocated and remote collaboration enabling remote gesture visualization
François Coldefy, Stphane Louis-dit-Picard · 2007
We present DlGlTABLE, an experimental platform we hope lessen the gap between co-present and distant interaction. DlGlTABLE is combining a multiuser tactile interactive tabletop, a video-communication system enabling eye-contact with real size distant user visualization and a spatialized sound system for speech transmission. Based on a robust computer vision module, it provides a fluid gesture visualization of each distant participant whether he/she is moving virtual digital objects or is intending to do so. Remote gesture visualization contributes to the efficiency of distant collaboration tasks because it enables the coordination among participant's actions and talk. Our main contribution addresses the development and the integration of robust and real time projector-camera processing techniques in computer supported cooperative work.
