Individually Adapted Imagery Improves Brain-Computer Interface Performance in End-Users with Disability

Fig 2

Between-day variability results.

(a) Simulated peak TPR and TNR values (color coded), respectively, for the segment S_t with the highest $GMAC=\sqrt{TPR\cdot TNR}$ during the imagery period (t = [3.0, 3.5, …, 9.0]s). The column on the right list the median GMAC (md) and the number of subjects (n) with GMAC > 70%. (b) Mean TPR and TNR curves for day two, averaged over all participants, for each mental task pair individually.
