Designer of award-winning wheelchair for quadriplegics, researcher Ravi Vaidyanathan has come out with some new groundbreaking technique for application of computers via your tongue movements.

The innovation reveals that by inserting a small microphone into the ear, the vibrations from the air pressure changes caused by the tongue can be detected and distinguished for computer commands. Whereas the pressure waves are mainly, sound waves and possess different wavelengths and amplitudes, equivalent to the direction, speed and intensity of the tongue movement.

The group further explains that certain tongue movements can cause fluctuations in air pressure from the ear. Though, the exact mechanism that transfer is still a mystery but its results definitively exhibits that when you move your tongue, the resulting waves inside your mouth propagate through bone, tissue and air into the ear canal. Moreover, as ear canal is apt to capture and amplify sound waves, one can measure these waves via microphone.

Though, researchers have also designed a test and classification system to discern four different tongue movements signals those are unique for every individual. Nevertheless, it is worth mentioning that this hands-free, non-intrusive method for computer applications will certainly bring some light in the lives of almost millions of people suffering with quadriplegics (high spinal cord accident) to spend more independent and productive lives.
