Evaluation of a Compact Hybrid Brain-Computer Interface System

Figure 1

Channel layout of near-infrared spectroscopy (NIRS; Ch1–Ch9) and electroencephalography (EEG; (a)) and a headgear setup on a phantom head (b). Five sources (red circles, 1–5) and three detectors (green circles, 1–3) are located around Fp1, Fpz, and Fp2. Fourteen electrodes are located at Fz, F3, F4, F7, F8, C3, C4, T7, T8, Pz, P3, P4, P7, and P8. Reference and ground electrodes are located on TP9 and TP10, respectively.
