EEG-Based Brain-Computer Interactions in Immersive Virtual and Augmented Reality: A Systematic Review

Brain-computer interactions allow humans to passively or actively control computer systems using their brain activity. For more than a decade now, these interactions have been implemented and evaluated in immersive virtual environments where they prompt novel means of human interaction with systems. In this paper, we present a systematic review of 76 studies published over the last 10 years that develop and evaluate immersive virtual reality or augmented reality systems with electroencephalography-based interactions. The aim of the review is to summarize and highlight trends in technology design, research methods, current practices, techniques used in systems of this kind, challenges and opportunities that present direction for future research in this area. Our analysis uncovers useful insights, limitations, and highlights of the trends, innovations, and usability and technical challenges at the intersection of brain-computer interfaces and immersive technologies, as well as recommendations for future research. © 2023 ACM.
