Washington: A wireless device helps people with severe spinal injuries operate a computer or move an electrically powered wheelchair by simply by moving their tongues.The sensors track the location of a tiny magnet attached to the users` tongues. In earlier versions of the tongue drive system, the sensors were mounted on a headset worn by the user."By moving the sensors inside the mouth, we have created a tongue drive system with increased mechanical stability and comfort that is nearly unnoticeable," said Maysam Ghovanloo, associate professor of computer engineering at the Georgia Institute of Technology, the US.
