Tongue operated electric wheelchair
2010 (English)Conference paper (Other academic)
In this paper we propose a tongue operated electric wheelchair system to aid persons with severe disabilities. Real-time tongue gestures are detected and estimated from a video camera pointing to the face of the user. The tongue gestures are used to control the wheelchair. Our system is a non-contact vision system, making it much more convenient to use. The user is only required to move his/her tongue to command the wheelchair. To make the system easy to drive, the system is also equipped with a laser scanner for obstacle avoidance. We also mount a 2D array of vibrators on the chair to provide the user with the information of the response from his/her tongue movement and the status of the system. We are carrying out user tests to measure the usability of the system.
