Non-Verbal Communication for a Virtual Reality Interface

The steady growth of technology has allowed to extend all forms of human-computer communication. Since the emergence of more sophisticated interaction devices, Human Computer Interaction (HCI) science has added the issue of Non-Verbal Communication (NVC). Nowadays, there are a lot of applications such as interactive entertainments and virtual reality requiring more natural and intuitive interfaces. Human gestures constitute a great space of actions expressed by the body, face, and/or hands. Hand Gesture is frequently used in people’s daily life, thus it is an alternative form to communicate with computers in an easy way. This paper introduces a real-time hand gesture recognition and tracking system to identify different and dinamic hand postures. In order to improve the user experience, a set of different system functions into a virtual world had been implemented so interaction can be performed by the user through a data glove device.
