Recent multi-touch multi-user tabletop systems offer rich touch contact properties to applications. Not only they pro- vide touch positions, but also finger orientations. Applica- tions can use these properties separated for each finger or derive information by combining the given touch contact data. In this paper, we present an approach to map fingers to their associated joined hand contributing to potential en- hancements for gesture recognition and user interaction. For instance, a gesture can be composed of multiple fingers of one hand or different hands. Therefore, we present a sim- ple heuristic for mapping fingers to hands that makes use of constraints applied to the touch position combined with the finger orientation. We tested our approach with collected di- verse touch contact data and analyze the results.
