The Design and Implementation of 3D Hand-based Human-Computer Interaction Platform
Virtual 3D hand is a natural and efficient tool of human-computer interaction (HCI), which is widely used in virtual reality (VR). In order to meet the needs of 3D Handbased HCI, a novel platform is presented in this paper. Firstly, using cascade local coordinate systems and two direction vectors of hand, a new 3D hand model with a better design of thumb is developed. The presentation of articulated object is discussed in detail. Secondly, we demonstrate a method which synthetically utilizes the data glove and position tracker. According to the analysis of the rotating hand, we established the relationship between angles of position tracker and model parameters. Finally, the 3D Hand-based HCI platform using VC++ and OpenGL is presented. Experimental results show that, our 3D hand model can express a variety of gestures and the platform design is feasible and can meet our requirements. It also laid the foundation for free hand tracking.
