Applications of Bioelectricity Signals in Intelligent Wheelchair

Differing from the image-based computer vision technique and the technique of measuring the physical caused by human parts motion, the bioelectricity signals reflect the behavior intention of human's body directly. The relational messages extracted from the bioelectricity signals can be converted into signals for controlling the wheelchair. This paper recites the primary works, emphasis and direction in steering the wheelchair using bioelectricity signals.
