Wheelchair controlled by thought

Michael Callahan hopes to assist individuals without the use of speech and mobility to communicate through the application of neuroscience. By interfacing near the source of vocal production, he has been able to translate unspoken thought of the mind from intercepted neuronal activity at the vocal cords. The method that Callahan has developed produces complete fluent speech with 70% accuracy from neurological signals.

Another concept from Japan: A team of researchers led by professor Kazuo Tanaka from University of Electro-Communications has developed a prototype of an electric wheelchair that users can use their brain to control simply by thinking of which direction to head towards. Before taking the mind-controlled wheelchair for a stroll, you’d need strap on a skullcap outfitted with a network of sensors. The sensors interpret the users brain waves, allowing the user to control the wheelchair’s direction by thinking, “move left” or “move right.” It’s amazing that the wheelchair is 80% accurate in interpreting the users intentions and moving in the desired direction.
