In one of my previous posts, I had mentioned about Mind Controlled Wheelchairs developed by Toyota. This time a tongue controlled wheelchair (and a computer) was approved to be very promising device as a solution to Quadriplegia for the future after several clinical tests.
Quadriplegia is the medical term where a person loses his ability to control all of his limbs. It is generally a result of severe spinal cord injuries. A grain of rise sized special magnet is attached to patient’s tongue. There is an wireless headphone worn by patient which captures the movement signals from the magnet wirelessly and this information is passed to the computer on the wheelchair. This way, the patient can control both computer and wheelchair. I hope there will be affordable mass production of such useful devices.
