Unlocking the Mind: Revolutionizing the Metaverse with Brain-Computer Interfaces

The current exploration of the Metaverse has now become a focus of research as research has deepened and technology has improved. Based on summarizing the experience of previous research, this paper explores the relationship between Brain-Computer Interface (BCIs) and Metaverse, and analyzes the possibilities, diversity, and creativity that BCIs offer to Metaverse research. Through user cognitive state monitoring, digitized body control, virtual interaction, and imagined voice communication, BCIs enhances the connection between the human brain and external devices to produce a more realistic feeling, thus making it seem as if one is immersed in a world that is unprecedentedly real and unnoticeable. In addition, this paper will focus on the role and application of virtual interaction in four different periods: online shopping, gaming, learning platforms and scientific research. There exists great progress in the application of Metaverse and BCIs in education, healthcare, social contact, and industrial engineering, but there are still many issues to be resolved in cybersecurity, health risks, and ethics.
