Results of the 3D postioning user study

The higher complexity levels of the positioning task require much more time and produce many more errors irrespective of the input method applied. ANOVA found that the positioning task was performed significantly faster with the 3D glove (M=139.1 s, SD=12) than with the 2D glove (M=198.4 s, SD=21.5), F1, 29=11.4, p=0.002. As can be seen in Fig. 9-left, the decrease in the task completion time was much higher for Levels 2 and 3 than for Level 1. The discovered significant differences between 2D and 3D input were 88.3 s (p=0.001) for the most complex trial (Level 3) and 71.8 s (p<0.001) for the slightly less complex trial (Level 2).
