Eye control ain’t nuthin’ — try brain waves. The Big NeuroSky (are we mispronouncing?) is working on such an interface, operating a Nokia handset with just the power of thought. Looks like we’ll be placing more of those 900-number calls than we planned.
But this interface, once fully developed and robustly commercialized, could be an answer for the millions of people worldwide who cannot make any reliable, repeatable physical action. Buy it for the phone, use it to run your Xbox and wheelchair.
