Objectives To use all planes in the environment as flexible virtual displays precisely at position where we want it be. with precise size that we want it be. without any distortions. on multiple planes (and even on their boundaries). by easy set-up.
Mechanism of FC-PT Projector A Projecter is placed on rotatable stage so that its projection center precisely corresponds to the rotation center. The projection center is fixed independent of the orientation of the projector. “ Tangent plane ” is introduced to integrate image planes of all orientations. All planes in the environment are also described on “ tangent plane. ” corresponding area of P 1 wall R tangent plane Q FC-PT projector corresponding area of P 2 relation H wall R tangent plane Q FC-PT projector
Future Works and Applications Future works Automation of set-up task. Cooperation of multiple FC-PT projectors. Projection onto the non-planar surfaces or moving objects. Applications : applicable to many applications for displaying visual information in ubiquitous computing environment. Ubiquitous TV displays, virtual posters. Human navigation, annotation to the environment. etc …
