Real-Time Hand Gesture Recognition in a Virtual 3D Environment
David Ferstl, Matthias Rüther, Horst Bischof · 2012
We present a novel technique using a range camera for real-time recognition of the hand gesture and position in 3D. Simultaneously the user’s hand and head pose are tracked and used for interaction in a virtual 3D desktop environment. As human gestures provide a natural way of communications between humans, gesture recognition is a major field of research used also for humancomputer communication. Most existing hand interaction systems are restricted to a 2D touch-sensitive plane, or track and recognize the hand gesture on color images. Due to the lack of depth information, these systems are limited to the 2D space only, provide little depth invariance and are sensitive to rotation and segmentation errors, whereas we built a system for bare-hand 3D interaction, independent from hand rotation and depth.
