PRINCIPLE OF USING BUNEMAN FREQUENCY ESTIMATOR FOR EYEBROW MOVEMENT CONTROL OF MOTORIZED VEHICLE FOR PHYSICALLY IMPAIRED

摘要

The current invention relates to a method in which a motorized chair can be controlled by physically challenged person.Occurrence of muscular movements prompts in frequency shift in the EMG signal.Buneman frequency estimator based on the fast fourier transform is used to detect the occurrence of muscular movements used to control the motorized chair.
