Human Centered Ubiquitous Display in Intelligent Space

Projection based information display system is proposed in this paper. Normally, human should approach information sources which are located around our living environment, e.g. bulletin boards, artificial signs, local maps, etc. However, the proposed system is able to afford human with relevant information by projecting it on where the human is facing in so that the human does not need to move for seeking information. The proposing system is based on intelligent space and a projector mounted mobile robot which is called ubiquitous display.
