I came across an article about a fascinating and novel way of controlling a wheelchair for people with extreme motor skill difficulties… tongue piercings.
I kid you not, a team of researchers at Georgia Tech in Atlanta have come up with a way for a quadriplegic to drive a powered wheelchair using the positioning of the metal tongue piercing in their mouth. Useful and weirdly kinky, my two favourite things!
Basically the user wears a headset, and the relative position of the tongue in their mouth moves/directs the chair. Forward, back, left and right etc. A really excellent use of technology we already have. Two thumbs up.
I wish I still had my tongue piercing!
