TABLE 3.

The area under the curve (AUC) of the experimental receiver operator characteristic (ROC) of GVTD and angular rotation (based on the motion sensor outputs), and the mean of the ROC of the absolute signal amplitudes and windowed amplitude changes based on the instructed motion as ground truth, in Data set 2.

Motion index	GVTD (either nn1 or nn2)	Angular rotation	Signal amplitude	Windowed amplitude change
AUC	0.88 ± 0.08	0.77 ± 0.08	0.6 ± 0.04	0.76 ± 0.04
