A Pilot Study using Covert Visuospatial Attention as an EEG-based Brain Computer Interface to Enhance AR Interaction

In this work we propose a prototype which combines an existing augmented reality (AR) headset, the Microsoft HoloLens 2, with an electroencephalogram (EEG) Brain-Computer Interface (BCI) system based on covert visuospatial attention (CVSA) – a process of focusing attention on different regions of the visual field without overt eye movements. In this work we did not rely on any stimulus-driven responses. Fourteen participants were able to test the system over the course of two days. To the best of our knowledge, this system is the first AR EEG-BCI integrated prototype that explores the complementary features of the AR headset like HoloLens 2 and the CVSA paradigm.
