For those with upper-body disabilities, using a computer can be quite challenging. While voice recognition software has advanced to a stage where you can orate an essay and see it typed out, in some cases cursor control may involve a touch screen and a straw held in the mouth.
Designer Liu Yi has come up with the Toe Mouse, which, as its name suggests, is made for the feet. Gripped between the big toe and the second toe (as with a pair of flip-flops), this wireless peripheral uses an optical sensor and two buttons to give physically challenged users full mouse capabilities. A concept design for now, this device begs the question: how will users change batteries when the mouse runs out of power?
