One of the next major frontiers for is bypassing the motor component (read the use of hands or voice) in the use and control of computers.  Significant advancements have been made in the last decade on this front, but the field is in its infancy.  Recent news items are about scientistist building a mind reading computer (Scientists Build Mind-Reading Computer), the use of a brain implant to use a robotic arm with monkeys, the neuroimpulse activator (a direct brain signal replacement for the mouse), artificial retinas to help restore sight with a direct interface to the neurons in the eye, and Dean Kamen’s robotic arm with the precision to pick up a piece of paper.  

Whereas there have been a number of advancements in this area, the complexity of the human mind is currently far beyond the comprehension of the human mind.  Current research and development is aiming towards the fantasies of science fiction writers, but is nowhere close to achieving those ends.  Computer science has not achieved anything close to human intelligence in the realm of artificial intelligence.  Raw computing power has shown progress in the area (see Deep Blue defeats chest master Kasparov); however, there is nothing that even approximates the computing power and complexity that was designed by God.
