Using Tongue to Control Wheelchairs

Posted on 07 July 2009 by admin

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.

Brain Controlled Wheelchairs by Toyota

Posted on 29 June 2009 by admin

Previously, we had seen brain controlled Japanese robot and Brainloop Mental Machine which enable the users to control devices and robots just by thinking.

Toyota developed the best social application of brain signals processing to help the people who are bound to wheelchairs. The user of the wheelchair just need to think about the commands of left, right turns or forward motion. All is thanks to real time fast calculations of one line EEG signals. The brain waves of the person is analyzed every 125 milliseconds and the results are translated into real mechanic movements. An accuracy of 95% was achieved.

Expect to see commercialized brain controlled wheelchairs in not very far future.
