A Synchronized Hybrid Brain-Computer Interface System for Simultaneous Detection and Classification of Fusion EEG Signals

Figure 2

Graphical user interface for the hybrid BCI system. (a) The caption EEG tasks shows the 10 mental tasks to be performed, which include idle state, MI task, SSVEP task, Freq. A-SSVEP task, Freq. B-SSVEP task, Freq. C-SSVEP task, Freq. D-SSVEP task, MI + Freq. A-SSVEP task, MI + Freq. B-SSVEP task, MI + Freq. C-SSVEP task, and MI + Freq. D-SSVEP task. (b) Time window for the performance of tasks divided into 2 parts for clarification, 0–3 s (rest state time) and 3–8 s (task-performing window). (c) Signal acquiring from the above performed tasks. (d) Processing, extraction, and classification of signals.
