Since the first electric version, a lot of arrangements have been done in Electric Powered Wheelchair to attend a wide and increasing types of user's needs. Many applications have evolved from a single into multimodal input methods that allow one wheelchair to support various types of disability. In cases of severe impairments, Brain-Computer Interface and Eye Tracking are commonly applied. Both input interfaces have weaknesses overcame by combined operation instead of each one independently. This proposal allows the user to command an Electric Power Wheelchair by information fusion from commercial Brain-Computer Interface and Eye Tracker devices, surpassing challenges of non-intentional commands and high workload of the user. Thereby, it is expected this user-wheelchair interface to be simple, safe and afford a better user experience.
