摘要：
A method of commanding and controlling a mobile apparatus (wheelchair) based on the assimilation of visual parameter and brain activity data includes validating a desired position of gaze (the iris) in the environment using the physiological brain characteristics of the potentials mentioned in P300 and SSVEP. These supply a control unit and are used to assess the users state of mental fatigue using an algorithm based on the theory of evidence. A unit detecting the users emotional state is also implemented using the alpha and beta waves from the parietal, central and frontal region of the cerebral cortex and the users heart rhythm. The assimilation between these two units makes it possible to define a mode of operation in real time: manual, semi-autonomous or autonomous, which corresponds to the users emotional or fatigue states as well as the characterization of the environment (safe path, detection of obstacles, locked situation).
