In this report, a human hand gesture recognition system is proposed. The system can understand both static and dynamic human hand gestures. So far, the system is able to recognize 9 static hand gestures: numbers from one to nine; and 1 dynamic hand gesture: number ten. In the system implementation, a right-hand CyberGlove II is used to get the accurate and stable hand joints information for the static hand gesture recognition. Based on the results of static classification, together with the hand joint motion information from Microsoft Kinect, dynamic hand gestures can be classified. In addition, and effective and fast human hand gesture recognition algorithm is proposed to manage the data from sensors and achieve classification results in real time. To verify the effectiveness of the system, a human hand gesture sample dataset containing 250 samples collected from 5 people of difference body sizes is constructed. The testing results show that the algorithm is able to understand human hand gestures accurately and fast.
