Article:Brain port...A blind can see now

A blind woman sits in a chair holding a video camera focused on a scientist sitting in front of her. She has a device in her mouth, touching her tongue, and there are wires running from that device to the video camera. The woman has been blind since birth and doesn't really know what a rubber ball looks like, but the scientist is holding one. And when he suddenly rolls it in her direction, she puts out a hand to stop it. The blind woman saw the ball. Through her tongue. Well, not exactly through her tongue, but the device in her mouth sent visual input through her tongue in much the same way that seeing individuals receive visual input through the #-Link-Snipped-#. In both cases, the initial sensory input mechanism -- the tongue or the eyes -- sends the visual data to the #-Link-Snipped-#, where that data is processed and interpreted to form images.

Good one but one question - Can she see the scientist or it works only for non-living things only ? One more -This mechanism works up to what distance from the blind person?
