With the steady price reduction of 3D visualization devices such as Head Mounted Displays (HMDs) and more recently 3D TVs, we can now foresee the dissemination of applications that was only possible within very expensive virtual reality environments. However, interaction within virtual 3D environments requires more natural modes than those provided by the ubiquitous mouse and keyboard. In this paper we introduce a novel low cost 3D hand gesture based interaction system. We have developed a real-time stereo computer vision system and a hybrid interface that combines natural and symbolic gestures for navigation and manipulation of 3D objects in virtual environments. Results from a pilot study reveals that the hybrid interface presents great power and flexibility without significant increase in the complexity of the user interaction.
