From: medGadget - 07/11/2013

Marton Juhasz and Now Technologies, a firm out of Hungary, have developed the
GyroSet, an Android tablet-powered system that allows a person to use his
head to guide the wheelchair's movements. A headset is worn that constantly

interprets the movements and sends signals to the electric wheelchair. The
system is cheap to implement and removes the annoying joystick from the front
of the face, giving a bit of liberation for the severely disabled.
