This project develops and tests a Bluetooth compliant tongue-based electronic controller (a.k.a. Mouth Mouse), designed to give people with upper limb disability control of peripheral devices including computers and communication systems, home automation, and powered wheelchairs, as well as many other Bluetooth compliant devices and new technologies to come in the future. The Mouth Mouse is encased in an oral appliance or retainer and the user slides the tongue across the roof of the mouth to move a cursor, make selections, or issue commands to a computer or other interactive technology. Phase I of this project includes engineering analyses and fabrication on the Bluetooth Mouth Mouse and usability and acceptance testing.
