Real-time natural hand gestures

In human-computer interaction (HCI) applications, traditional devices, such as keyboard and mouse, can become cumbersome and unsuitable. Researchers consider the human hand to be one of the most promising natural HCI media; specifically, using hand gestures to input computer commands. Vision-based HCI hand-gesture analysis and recognition studies require large numbers of a variety of gestures as input and a virtual hand as output to display the results. Creating a virtual hand with natural gestures would improve human hand HCI research by providing data for hand analysis systems and generating visual output for hand simulation systems.
