Abstract

This paper introduced a user interface based on virtual shadow derived by projector for spatial augmented reality (SAR) environment. Shadow is a daily phenomenon in our daily life and may contribute to build an effective and intuitive connection between physical and digital world. Taking advantage of spatial and optical characteristics of shadow, user can realize remote interaction for ubiquitous interface. The prototype system is implemented and adaptive image processing algorithms for shadow are proposed. The authors has demonstrated in this paper that shadow has possibility to realize simple but effective interface between human and computer systems, which may yield to many useful applications without massive device resources
