Table 1.

Means ± standard deviations across all three conditions ($n=25$) for cognitive load (NASA-TLX; [0, 100]; lower is better), user preference (Likert scale; [1, 5]; higher is better), usability (SUS; [0, 100]; higher is better), task time (s), and accuracy (mm)

Cognitive load	$27.3\pm 13.85$	$29.37\pm 14.03$	$37.6\pm 14.91$
User preference	$4.44\pm 0.65$	$4.56\pm 0.71$	$3.6\pm 1.08$
Usability	$82.2\pm 12.96$	$78.2\pm 14.35$	$71.0\pm 14.51$
Task time	$39.63\pm 28.41$	$44.43\pm 29.87$	$46.36\pm 26.09$
Accuracy	$20.42\pm 3.36$	$20.29\pm 3.84$	$22.01\pm 4.12$
