Abstract

This work presents a Human-Machine Interface (HMI) development based on Steady-State Visual Evoked Potentials (SSVEPs). The Goertzel transform was used in this proposal to identify the stimulus frequencies present in electroencephalogram (EEG) signals. A maze game was created as a mobile application to relate the stimuli to navigation commands. The preliminary results show a hit rate above 85\%. Besides, the system is structured to insert Augmented Reality (AR) tools.
