Some issues on direct-projected augmented reality (DirectAR) are addressed: the projection may be geometrically distorted due to the non-planar surface (geometric distortion); the projection cannot be seen to user as intended because the position of the projector is not the same as that of the user's viewpoint (viewpoint-ignorant projection); the projection(More)
In direct-projected augmented reality, use of projector makes it possible to utilize 3-D real and large objects as displays and frees from discomforts incidental to wearing a device such as HMD. However, the resulting augmentation usually has poor depth resolution due to projectors with low contrast. In direct-projected augmented reality, the radiometric(More)
In projection-based augmented reality, specular reflection may distract the users. This paper demonstrates that the specular reflection can be eliminated by redundantly illuminating the projection surface using multiple overlapping projectors mounted at different locations. Our initial system using two projectors is presented. The system automatically(More)
In this paper, we introduce a new active information display system which is based on Intelligent Space and a projector mounted mobile robot. This system 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. For this system, Intelligent Space should recognize location of(More)
