TouchLight
an imaging touch screen with some unique
capabilities

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

• Track shaped laser pointer (hologram)
• Theoretically 6 degree of freedom
• Today, 4 position, depth, roll

Surface Computing Challenges

• Display and Sensing
• e.g. Projector computer vision
• Interactions
• e.g. Two handed, multi-user
• Applications
• e.g. Mapping
