Thinking Cap Brain-Computer Interface

Nature.com says that computer scientists have created a hat that can read your thoughts. Called a brain-computer interface, the device detects activity in certain brain areas linked to movement, and uses the signals to mimic that movement in a virtual world. The scientists setup a virtual road and the users just "think" to walk themselves down the street or grab objects. This could lead to help for those who are paralyzed or physically unable to move otherwise. Remember the story about the Rhesus Monkey that could control a robotic arm that we reported on before?
