Making environments as canvases - Ubiquitous Display, from 2D to 3D -

This paper describes a projection based information display system which is called Ubiquitous Display. In usual cases, a man should approach information sources which are located around our living environment; e.g. bulletin boards, artificial signs, local maps, etc. However, the Ubiquitous Display is able to afford a human with relevant information by projecting it on where the human is looking such as a wall, a floor and a door so that the human does not need to move for seeking information. The Ubiquitous Display can make a user see 3D objects as well as 2D objects with naked eyes. Anamorphosis technique is adopted for a human to perceive a 3D structure from a 2D image by psychological effect. In this paper and video, how the Ubiquitous Display has been developed and its functions are introduced.
