摘要:: 表面肌电信号（surface EMG, sEMG）是人体产生的一种生物电信号，它蕴含信息丰富并且与肌肉活动和运动状态之间存在着很大的关联，可以用来识别运动意图和利用肌电反馈评估肌肉功能状态。目前，随着虚拟现实技术的发展，研究人员也逐渐将sEMG的应用与虚拟现实相结合。本研究总结了肌电-计算机接口的发展现状及其在虚拟现实中的应用。最后，探讨了基于虚拟现实的肌电-计算机接口目前存在的技术难点，并对其未来发展进行了展望。

Abstract:: Surface electromyography（sEMG） signal is a bioelectric signal produced by the human body. It contains much information and it is associated with muscle activity and movement. Surface EMG signals can be used to identify the movement intention and evaluate function status of muscle. At present, sEMG is used in virtual reality with development of virtual reality technology. This paper summarized the development of EMG-computer interface and its application for virtual reality. Finally, the issues of EMG-computer interface based on virtual reality were discussed, and future development of the EMG-computer interface based on virtual reality was presented.
