Controlling with thought
Using the brain to control a physical object seems like something right out of science fiction but controlling with thought is getting closer to reality all the time. Of course, we haven’t yet gotten to the same point as in Star Wars where Yoda can levitate a heavy object some distance off. However, using the electrical signals from the brain to actuate computer controlled devices is here already.
Having recently found myself in a wheelchair a good part of the time, I was intrigued by the announcement that Toyota was developing a thought-controlled wheelchair. TechNewsWorld reports:
Toyota has developed a brain-machine interface that allows a person to steer a wheelchair simply by thinking about which direction to go. Brain waves have been used to directly control machines in the past; however, the breakthrough involved in the Toyota project appears to be the speed at which commands are executed.
