Abstract:

For severely disabled patients who are unable to move freely because of their disability, a wheelchair control method based on EEG was presented. The EEG sensor collects the EEG data and sends it to the core control module via bluetooth. The improved wavelet transform method, co-space mode method and fuzzy support vector machine were designed to realize denoising, feature processing and pattern recognition processing of EEG signals. Finally, the path planning based on ant colony algorithm was combined to meet the requirement for wheelchair to reach the destination accurately without collision.

Key words: EEG, wavelet transform, feature extraction, pattern recognition, path planning
