Midair Gestural Techniques for Translation Tasks in Large-Display Interaction

Table 4

Bonferroni corrected post hoc pairwise comparisons of ER for all interaction techniques.

Interaction technique		Mean difference	Significance ()
Less accurate	More accurate	(MD)
Long distance
Pinch	Fist	1.771
Pinch	Palm	2.084
Fist	Sideways	0.687
Pinch	Sideways	2.423
Short distance
Pinch	Fist	1.098
Pinch	Palm	1.417
Fist	Palm	0.421
Pinch	Sideways	1.206

As we can see from the table, the pinch was the worst in accuracy at both distances, but the fist was less accurate than the sideways at the long distance and the palm at the short distance.
