Applications of projection based interactive user interface

Abstract

Recently, there were various approaches based on the interactive projection system as a user interface due to its broad applicability to projection surfaces[Wilson 2005][Cao et al. 2007]. Among projection surfaces, whiteboard is regarded as the most appropriate media to interact with people by writing or drawing. Throughout this work, we propose an interactive user interface system and some applications for whiteboard based on the projector. This system supports interactions by hand-drawing detection and simple hand-gesture recognition(moving or clicking).
