Real World Hand Gesture Interaction in Virtual Reality
Qi Zhang, Wenzhe Zhu, Qing Zhu · Journal of Physics Conference Series · 2019
Abstract With the development of virtual reality, the appropriate interaction technology has become the focus of practitioners. Today’s virtual reality interaction is mostly through the interaction of traditional electronic devices, such as handles and other products, temporarily solve the problem of interaction, but also make the user from the virtual world is taken out, immersion greatly reduced. The paper uses hand gestures to interact with virtual reality. By using skin detection in YCbCr color space and indicates the location of hand to determine the approximate range of hand. Then, the histograms of oriented gradient (HOG) which has been widely used in target detection research in recent years is used to extract gesture features, and applies support vector machine (SVM) method to achieve the real-time hand gesture recognition. Finally, experiments prove that the proposed method is accurate and stable in virtual reality interaction.
