Virtual Reality Cognitive Gaming Based on Brain Computer Interfacing: A Narrative Review.

The present article explores the most popular approaches and the best practices for the design and implementation of cognitive gaming interventions that combine Brain Computer Interface (BCI) systems with Virtual Reality (VR). We focus on interventions that target cognitive skills related to perception, visuospatial attention and visuospatial memory. To this purpose, we review the techniques and algorithms that are commonly used for data pre-processing, feature extraction, and classification in such interventions. We discuss issues related to BCI-VR Cognitive Gaming, including the BCI paradigms, the action tasks and environments, user characteristics, algorithms, channels, accuracy, and the most prominent findings. We conclude with a discussion of the current challenges, limitations, future research directions, and the potential commercial applications of BCI-VR in cognitive gaming.
