Brain-computer interface combined with augment reality

The development of the Brain-Computer Interface (BCI) has provided humans with a novel channel to interact with the world directly, and the join of Augmented Reality (AR) makes it more natural and practical in an immersive experience. This paper aims to give a review of the research status of the BCI system combined with the AR environment. The fundamental introduction of the two techniques is illustrated at first. And the progress and application made in recent years are stated in three main dimensions about the interface, application field, and related testing work. Finally, it discusses the future challenge of the actual operation in a common environment covering various real-life scenarios, and summarizes its broad prospects.
