He invented the Grafitti handwriting recognition system and helped develop the Palm Trio SmartPhone. Since he published his bestseller On Intelligence, he has devoted his work to his passion for neuroscience. His current company Numenta is developing software that models the hierarchal structure of the neocortex. In this interview we talk about the ideas in Hawkins book and how he is applying them to develop a computer model of cortical function.
