Interestingly enough, the tongue generally stays active even in the event of massive trauma or disease it’s the perfect candidate for controlling wheelchairs and other communications and wheelchair control systems. Students at Georgia Tech created a unique system that uses the tongue and a few tiny embedded magnets, allowing quadriplegics to control multiple devices just by flicking their tongues. Because the tougue is very agile, the new system offers a considerably more nuanced control system than the standard puff system used by many devices. Amazing stuff.
