Surface Computing Turning everyday surfaces into interactive intelligent interfaces Co-located input and output Mixed reality: tangible objects, natural interactions with direct manipulation

TouchLight an imaging touch screen with some unique capabilities

“Lunchbox” interactive vision system

PlayAnywhere Short-throw projector, very wide angle lens on the camera Lens distortion & projective transform correction for camera-projector alignment Off-axis IR LED illuminant Very few assumptions about the appearance of the surface All calibration is done at the “factory”

Flow Move Summarize optical flow field as simultaneous translation, rotation, scaling

Bluetooth Photo Sync

Mini PlayAnywhere

IR Laser Pointer Tracking Track shaped laser pointer (hologram) Theoretically 6 degree of freedom Today, 4: position, depth, roll

AirStylus With Mike Sinclair Activate by thumb and forefinger together

Surface Computing Challenges Display and Sensing e.g. Projector + computer vision Interactions e.g. Two handed, multi-user Applications e.g. Mapping
