Virtual reality for studying and improving BCI
Researchers can use VR to study and improve brain-computer interaction. The technology also helps
researchers perform safe and perfectly controlled experiments. For example, it has enabled the simulation
of wheelchair control with a BCI [3] and various BCI groups have used it to study how users would react
while navigating in a complex 3D environment using a BCI in close to real-life conditions [7][9].
Several studies have compared feedback consisting of classical 2D displays with feedback consisting of
entertaining VR applications [2][7]. These studies show that users’ performance ranked higher with VR
feedback than with simple 2D feedback. Moreover, evidence suggests that the more immersive the VR
display, the better users perform [7][10]. Even though some observations await confirmation, VR appears
to shorten BCI learning and increase users’ performance by increasing their motivation.
