A brain-computer interface (BCI) utilizing steady-state visually evoked potentials (SSVEPs) can facilitate communication for individuals with locked-in syndrome, a condition that severely impairs neuromuscular control. This human factors research insight is drawn from a 2014 study published in Journal of Neural Engineering. Using Experimental, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design assistive technologies that bypass traditional motor pathways by directly interpreting brain signals, focusing on user engagement and cognitive load.
