Data Glove Design and Virtual Hand Simulation Based on Single-chip Microcomputer

With the gradual development of virtual reality (VR) technology, users have increasingly higher demand for system interaction. The human-computer interaction (HMI) by means of data glove is a widely used interaction means in the current days. In this paper, a type of single-chip microcomputer based low cost data glove is designed for figure posture acquisition. Also, a programmable control virtual hand model is designed for simulation. And they are used for building a basic HMI system. In terms of hardware, the system adopts a single-chip microcomputer as the core of data processing and collects, processes and transmits hand posture data together with peripheral data acquisition circuit. In terms of software, mapping is established between the practical and virtual hand postures based on the strap-down navigation algorithm and the 3D skeletal animation algorithm, for the purpose of basic interactive application of data gloves.
