Feasibility of a Hybrid Brain-Computer Interface for Advanced Functional Electrical Therapy
Figure 5
Normalized band-powers BP1, BP2, BP3, and BPmu from (a) to (d). Three successful trials (TP), one per each LED, and one false activation of SSVEP-BCI (FPssvep) for subject S5, during the representative 100-second interval are presented. (a)–(d) arrangement and color codes for turquoise, red, blue, and green are the same as in Figure 4. Pink vertical dotted line marks one incorrect SSVEP detection when subject focused and reached for the second object (LED2), but SSVEP1 were falsely detected (threshold TH1 was exceeded by BP1 for ).
