Thought-controlled wheelchair
The prototype thought controlled wheelchair uses EEGs to figure out what the operator wants to do and where it wants to go. This way, people who have intact brains but squirrelly bodies can have control over their personal mobility (though obviously those of sound body are going to want to get more personal with their cars when given half a chance). The big difference between this project and previous projects is it uses electrodes placed on the scalp instead of a hard link screwed dangerously into the skull. “You’re not going to be using EEGs to control a robotic arm to play the piano or anything,” says Dawn Taylor, an assistant professor at Case Western Reserve University’s Department of Biomedical Engineering, who isn’t involved in the project. “But you can certainly turn right and left and stop and go using that sort of signal.” [GT]
