Abstract: A system allowing a person with severe neuromotor disfunction to choose symbols in a Personal Digital Assistent (PDA) using electroencephalography (EEG) or electromyography (EMG) is implemented onboard an electrical wheelchair. Through this system the user is able to elicit personal needs or states, like sleep, thirst or hunger; to write texts using an alpha-numeric keyboard and to command a robotic wheelchair. The EEG patterns used are event-related synchronization and de-synchronization (ERS and ERD, respectively) occurring in the alpha band of the signal spectrum captured in the occipital region of the head, while the EMG patterns are eye-blinks. The results so far obtained with the system developed, in indoor and outdoor environments, are quite satisfactory. This paper describes the system so far implemented and shows some experimental results associated to it.
