First Claim
Patent Images
1. A method for visual drive control, comprising the steps of:
- a) simultaneously presenting a set of flickering images that flicker at the same flicker frequency and that are associated with mutually distinct flicker patterns for viewing by an observer;
b) capturing evoked signals produced in the observer'"'"'s brain;
c) determining which one of the flicker patterns has a greatest similarity with the evoked signals captured in step b); and
d) generating a control signal corresponding to said one of the flicker patterns determined in step c).

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.

6. An apparatus for visual drive control, comprising:
-
display means for simultaneously presenting a set of flickering images that flicker at the same flicker frequency and that are associated with mutually distinct flicker patterns for viewing by an observer;
electrode means for capturing evoked signals produced in the observer'"'"'s brain; and
processing means, operatively connected to said electrode means, for determining which one of the flicker patterns has a greatest similarity with the evoked signals captured by said electrode means. - View Dependent Claims (7, 8, 9, 10, 11)
