Using a depth camera as a touch sensor (2010, background): “Benko et al s DepthTouch [4] applied a depth camera to TouchLight s display, to more easily detect touch.”
Precise selection techniques for multi-touch screens (2006, methodology): “However, with the recent emergence of many multi-touch prototype devices [1, 11, 14, 22, 25, 26], research on multi-finger and multi-hand touch interactions has increased [4, 7, 27].”
Lucid touch: a see-through mobile device (2007, methodology): “The system seen in [30] provides 3D position information of the hands.”
WUW - wear Ur world: a wearable gestural interface (2009, methodology): “The tiny projector is connected to a laptop or mobile device and projects visual information enabling surfaces, walls and physical objects around us to be used as interfaces; while the camera tracks user hand gestures using simple computer-vision based techniques.”
PlayAnywhere: a compact interactive tabletop projection-vision system (2005, methodology): “One method to perform sensing and detection of objects on the surface is to use two cameras and simple stereo calculations (as in [5, 19, 35, 36]), but with PlayAnywhere we chose to instead use one camera and explore simple image techniques that allow touch detection by examining the shadows of obje”
