Many assistive technologies have been developed to extend the capability of human to complete different tasks. Assistive devices such as intraoral interfaces, devices inserted into mouth, are particularly useful given the rich facial muscle abilities. In this paper, we present a novel multipurpose intraoral interface which aims to extend human's manipulation ability. Our intraoral interface consists of an inertial measurement unit (IMU) mounted on a stick attached to a ball joint. The user manipulates the stick using their tongue, and so is hands-free. The stick's orientation data is measured and translated into control commands. An additional IMU mounted on the head is used to compensate for head and body movement. Separate experiments to control a mouse pointer and an electric wheelchair were conducted to evaluate the performance of the proposed interface. The effectiveness of our proposed method as compared to conventional inputs are reported and discussed.
