In the physical world we use both hands in a very distinctive manner. Much research has been dedicated to transfer this principle to the digital realm, including multi-touch interactive surfaces. However, without the possibility to reliably distinguish between hands, interaction design is very limited. We present an approach for enhancing multi-touch systems based on diffuse illumination with left and right hand distinction. Using anatomical properties of the human hand we derive a simple empirical model and heuristics that, when fed into a decision tree classifier, enable real-time hand distinction for multi-touch applications.
