In one of the final presentations this afternoon at the Innovation Summit, a gentleman from NASA (Daniel 'Something') talked about a project they have been working on and one of the discoveries they had made. He said that when you think of a word, your vocal cords begin to vibrate. They have applied this as a way to do graphical control of a computer, moving a cursor in various directions based on these inaudible vocal chord vibrations. Amazing! My vocal chords are abuzz with vibrations but no actual words to describe my awe.
