“…Brain–computer interfaces (BCIs) based on electroencephalographic (EEG) signals are gaining considerable attention in scientific research and application development [ 1 ] because of technological advances and multidisciplinary studies related to brain signals [ 2 , 3 ]. Many categories of EEG signals can be processed, and countless BCI systems have been developed for ordinary use and clinical applications, for example, in the fields of brain-controlled vehicles [ 4 ], drones [ 5 ], assistive devices [ 6 ], intelligent systems [ 7 ], neurorehabilitation [ 8 ], telemedicine [ 9 ], assistive robots [ 10 ], and wheelchairs [ 11 ], to name but a few. Based on a user’s mental stimulation, event-related potentials (ERPs) are generated externally by cognitive load or auditory, sensory, or visual stimuli.…”
