Midair Gestural Techniques for Translation Tasks in Large-Display Interaction

Table 5

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

Interaction technique		Mean Difference	Significance ()
Less efficient	More efficient	(MD)
Long distance
Fist	Palm	1.709
Pinch	Fist	2.309
Fist	Sideways	4.103
Pinch	Palm	4.006
Palm	Sideways	2.211
Pinch	Sideways	6.544
Short distance
Fist	Palm	0.922
Fist	Sideways	2.121
Pinch	Palm	0.640
Palm	Sideways	1.476
Pinch	Sideways	4.226

As we can see from the table, the sideways was the most efficient at both distances, and the pinch was the least efficient than other techniques at the long distance.
