We have covered “intelligent” wheelchairs before, but one that can be controlled through facial muscles is new. A team of researchers at Japan’s Miyazaki University developed a system aimed at people paralyzed from the neck down or those who have lost muscular strength in their body for a reason. The way it works is pretty simple: the wheelchair, which is still in prototype mode, can be turned left or right by blinking the eyes and put into motion (and stopped) by clenching one’s teeth.
