schliz writes: University of Chicago researchers have built a robotic sleeve that improved the accuracy of thought-controlled computing by translating a cursor's movements into physical sensations. They found monkeys to moved a cursor to a target 40 percent faster when the sleeve moved their arm to provide feedback on the cursor's motion. The study was based on the concept of proprioception — the sensation of a body part's position and motion. The researchers expect brain-machine interfaces to be commercially available within five years.
