Research on the Virtuality-Reality Interaction Based on Dynamic Gesture Recognition in Augmented Reality System

摘要

The real-time human-computer interaction (HCI) is one of the three most important features of augmented reality (AR) technology. Hand is the part of body used most frequently for the Virtuality-Reality Interactions (VRI) in AR system. Because of the complicated physiological structure of hand and the flexibility of hand motions, it is a hot research topic to recognize the user's dynamic gesture (DG) accurately and to trigger the corresponding operations. In this paper, the dynamic gesture spotting algorithm based on the analysis of speed variation and the dynamic gesture recognition (DGR) algorithm based on fuzzy measure and fuzzy integral are proposed. The experimental results show that by using this method, users can operate the virtual objects easily. The interaction process is natural, which enhances the users' immersion feeling.
