Using the pressure waves in the ear caused by tongue movements, researchers have designed a technique for interfacing with computers. For the millions of people living with spinal cord injuries, this hands-free, non-intrusive method to work with computers could enable many people to lead more independent and productive lives.
Researchers Ravi Vaidyanathan et al., from the Naval Postgraduate School, Southern Illinois University, Case Western Reserve University, the University of Southampton, and Think-A-Move, Ltd, recently published their results on tongue control. They showed 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. The researchers have also designed a test and classification system to distinguish the signals of four different tongue movements, which are unique for every individual.
