Vision Based Hand Gesture Recognition

Hand gesture recognition has attracted much attention from academia and industry in recent years due to its apparent superiority over traditional techniques in human-computer interaction in terms of convenience. This domain has been investigated from different perspectives among which vision based approaches provide the most natural and intuitive interfaces. This paper presents a comprehensive review on vision based hand gesture recognition, with an emphasis on dynamic hand gestures. First, a brief introduction of the basic concepts and the classification of hand gesture recognition techniques are given. Then, a number of popular related technologies and interesting applications are reviewed. Finally, we give some discussion on the current challenges and open questions in this area and point out a list of possible directions for future work.
