This paper
examines a steerable projection system, the everywhere displays projector
(ED-projector), which transforms surfaces into interactive displays. In
an ED-projector, the display image is directed onto a surface by a rotating
mirror. Oblique projection distortion is removed by a computer-graphics
reverse-distortion process and user interaction (pointing and clicking)
is achieved by detecting hand movements with a video camera. The ED-projector
is a generic input/output device to be used to provide computer access from
different locations of an environment or to overlay interactive graphics
on any surface of a space, providing a simpler, more comfortable, and more
social solution for augmented reality than goggles. We are investigating
applications of ED-projectors that provide computer access in public spaces,
facilitate navigation in buildings, localize resources in a physical space,
bring computational resources to different areas of an environment, and
facilitate the reconfiguration of the workplace.
