Abstract: A brain computer interface as an alternative communication channel to be used in various applications, such as robotics. In one embodiment of the invention, there is provided a process for the analysis and conversion of EEG signals obtained from the brain into movement commands through electric and/or mechanical devices. The process of the present invention provides substantial advantages over the similar systems/techniques known in the art, such as a 91% average hit rate, obtained in attempts to control a mobile robot. In other embodiment of the invention, there is provided an apparatus comprising: means for obtaining brain signals; an electroencephalograph (EEG); and means for transducing said signals into functional commands useful in several applications. Said means for transducing mental signals is the core of the invention and provides a number of technical advantages over the similar systems/techniques known in the art of identifying mental activities.
