Scientists from Stanford University's BrainGate program revealed that a woman suffering Lou Gehrig’s disease can successfully control a Nexus tablet with her brainwaves.
The team built upon eye-tracking technology that uses eye movement to control mouse cursors and “click” by focussing on a single spot. However, the technology can be inaccurate and tiring for users.
The program instead “cut out the middleman” by implanting a baby-aspirin-sized 100-channel electrode microarray into the left side of the patient's brain that’s responsible for movement.
Neural signals were decoded in real time by algorithms to control the mouse cursor. This method let the patient type out words on a custom keyboard by concentrating on the words they wanted to spell.
