Presentation Transcript

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

  2. TouchLight an imaging touch screen with some unique capabilities

  3. “Lunchbox” interactive vision system

  4. 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”

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

  6. Bluetooth Photo Sync

  7. Mini PlayAnywhere

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

  9. AirStylus • With Mike Sinclair • Activate by thumb and forefinger together

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