Multi-touch gestural interaction in X3D using hidden Markov models

Figure 1: Painting application in X3D: recognized paintings created with gestural input were redefined. Multi-touch interaction on tabletop displays is a very active field of todays HCI research. However, most publications still focus on tracking techniques or develop gesture configurations for a specific application setup using a small set of simple gestures. In this work we present a new approach to easily set up the recognition of even complex gestures for multi-touch applications. Our gesture recog-nition module is based on Hidden Markov Models, which offer a robust recognition of multiple gestures in real-time. An X3D inter-face of the recognition module is provided to qualify designers and other non-programmers to apply gesture recognition functionalities to multi-touch applications in an easy and straightforward manner.
