36.4.2 Task 2–Layer Control

The result of the two-way ANOVA of task 2 indicated that the main effect of command operations was F = 50.35, P value = 0.000 < 0.05, there was a statistically significant difference in four types of command operations. The results of Fisher’s least significant difference (LSD) of command operations of task 2 indicated that there was a statistically significant difference in comparing graphical user interface (GUI, M = 13.84, SD = 1.29) to shortcut keys (SK, M = 10.28, SD = 1.84), pen gestures with a rubber grip pen and a keyboard (PGk, M = 9.35, SD = 0.93), and pen gestures with a rubber grip pen (PGr, M = 8.90, SD = 0.82). Graphical user interface (GUI) had the worst task efficiency among the four command operations. There was a statistically significant difference in comparing shortcut keys (SK, M = 10.28, SD = 1.84) to pen gestures with a rubber grip pen and a keyboard (PGk, M = 9.35, SD = 0.93), and pen gestures with a rubber grip pen (PGr, M = 8.90, SD = 0.82). The task efficiency of shortcut keys (SK) was worse than pen gestures with a rubber grip pen and a keyboard (PGk), and pen gestures with a rubber grip pen (PGr).
