Project Overview

MirrorTrack is a novel way to track gestures and touch interaction on a LCD or plasma screens. By placing the camera at a low azimuth angle over the screen, the screen surface becomes an almost perfect mirror. This means that visual interference from what is displayed on the screen is minimized, and we can use the reflection of a user's finger either touching or hovering over the screen in the gesture and touch tracking algorithm.

This yields an interesting solution because it is both very easy to implement and providing a good user’s experience by using a completely new method.Its main particularity is that it is inexpensive and can be setup with simple day-to-day devices. It opens the door to an enriched Touch experience for numerous users.
