Optical tracking systems allow three-dimensional inputfor virtual environment applications with high precision andwithout annoying cables. Spontaneous and intuitive interactionis possible through gestures. In this paper, we presenta finger tracker that allows gestural interaction and is simple,cheap, fast, robust against occlusion and accurate. Itis based on a marked glove, a stereoscopic tracking systemand a kinematic 3-d model of the human finger. Within ouraugmented reality application scenario, the user is able tograb, translate, rotate, and release objects in an intuitiveway. We demonstrate our tracking system in an augmentedreality chess game allowing a user to interact with virtualobjects.
