Commanding Wheelchair in Virtual Reality with Thoughts by Multiclass BCI based on Movement-related Cortical Potentials


Brain-driven wheelchair control is an attractive application in the
Brain-Computer Interface (BCI) field. In this research, we
designed and validated a virtual wheelchair navigation system
controlled by our latest multiclass BCI Menu interface based on a
fast brain switch, which provides five commands: move forward,
turn left, turn right, move backward, and stop. Preliminary results
have shown that subjects can successfully control the wheelchair
to hit all targets in the immersive virtual reality (VR)
environment. This system proves an avenue to bridge the gap
between simulation control in VR environments and real-life
wheelchair applications for mobility impairment.
