Ubiquitous display 2.0: Development of new prototype and software modules for improvement

Ubiquitous Display (UD) is a mobile projection robot that consists of mobile platform and projector with pan-tilt mechanism. This structure enables UD to project images on any surfaces such as a wall, a floor, or an object. In this paper, some structural issues of previous prototype are described. In addition, new prototype of UD re-developed to improve the issues and developing software modules are introduced.
