| Outline of Final Research Achievements |
The tongue motion is governed by the twelfth cranial nerve (hypoglossal nerve). The motor functions are usually preserved even in people with cervical spinal cord damage. In this study we developed a novel tongue interface based on the classification of the tongue motions from the surface electromyogram of the suprahyoid muscles detectable at the underside of the jaw. The tongue motion classification accuracy was evaluated by experiments which participants were five healthy adult men. The results revealed that all six tongue motions included in the tests were classified with accuracy of 95.1 ± 1.9%. The new interface does not require insertion of measuring sensors into the mouth cavity and thus, it does not hinders user’s activities such as eating, drinking, talking, and swallowing.
