Previous Research Projects

  • Kickables–tangibles for feet–scale to arbitrarily large spaces, while maintaining the affordance of traditional tangibles
  • GravitySpace is a new approach to tracking people and objects based on high-resolution, pressure-sensing floor.
  • PICOntrol uses an off-the-shelf handheld projector to remote control physical devices through visible light.
  • Personal Clipboards enable individual copy-and-paste on interactive surfaces.
  • PhoneTouch is a novel technique for integration of mobile phones and interactive surfaces. The technique enables use of phones to select targets on the surface by direct touch.
  • HandsDown enables user identification based on biometric hand contour analysis.
  • IdWristbands use infra-red LED to associate touches to users on multi-touch surfaces
