Research and prospects of virtual reality systems applying exoskeleton technology

As a typical application of human–machine fusion intelligence, the exoskeleton is an indispensable intelligent interaction device for virtual reality. At present, there are an increasing number of studies on virtual reality systems using exoskeleton technology, especially in the field of medical rehabilitation. In this paper, for the first time, a virtual reality system with the application of exoskeleton technology is considered as the research object. We refer to three key human–machine interaction processes: recognition, perception, and feedback. The virtual reality system that uses exoskeleton technology is divided into positioning technology, multisensory interaction, and feedback technology. First, this study conducts literature research and then summarizes the technical characteristics, system architecture, and research status for key content such as positioning technology, multisensory interaction, and feedback technology. Finally, the three research aspects of the virtual reality system applying exoskeleton technology are summarized, considered, and prospected.
