Abstract
Display light is modulated using frequencies invisible to human eye. A camera captures images and the known light modulation is used to isolate the display generated light. The resulting demodulated images do not depend on the ambient light conditions and the objects close to the display are clearly visible and easy to detect/track. Touch-screen like mid-air interaction with the display can be realized by robustly detecting human hands when they are close to the display.
