robots.net - Robot news and Robotics Info: "Forget about playing checkers or chess with a robot. Yukiyasu Kamitani and other Researchers at ATR Computational Neuroscience Labs have developed a system that does rock paper scissors by reading your mind. How does it work? You'll need to be inside an MRI scanner. A computer decodes the MRI output to identify the 'perceptual and subjective contents' of your brain. As you make rock, paper or scissors hand gestures, your brain configuration is used to control a robot hand that duplicates your movements. Obviously, the real goal here is to develop non-invasive methods of controlling prosthetic devices. So far the researchers have achieved 85% accuracy with a 7 second lag time on the current setup. The good part is that it works on anyone without surgery or special training. The bad part is that you need a massive MRI machine"
