Motorized wheelchair control using electrooculogram and head gear

A significant portion of our society suffers from one or the other kind of disabilities due to accidents or neurological disorders (eg: paralysis) etc. Due to these disabilities, the physically impaired are dependent on others for their everyday routine activities. To assist these patients, rehabilitation devices are used. These rehabilitation devices are controlled by generation of biomedical signals for example electro-oculogram(EOG) and Electroencephalography (EEG). EOG signal is captured by Ag/AgCl electrodes and EEG signal is captured by headgear. These signals are integrated by microcontroller which in turn controls the movement of the wheel chair.
