Abstract
In a method and apparatus for visual drive control, a set of flickering images that flicker at the same flicker frequency and that are associated with mutually distinct flicker patterns are simultaneously presented for viewing by an observer. Thereafter, evoked signals produced in the observer's brain are captured, and the flicker pattern having a greatest similarity with the captured evoked signals is determined. Finally, a control signal corresponding to the flicker pattern having the greatest similarity is generated.
