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).

无论采用何种输入方式，定位任务的复杂度等级越高，完成所需时长越长，产生的错误数量也越多。

方差分析（Analysis of Variance，简称ANOVA）结果显示，使用3D手套（均值M=139.1秒，标准差SD=12）完成定位任务的速度显著快于2D手套（均值M=198.4秒，标准差SD=21.5），F(1,29)=11.4，p=0.002。如图9左图所示，等级2和等级3的任务完成时间降幅远高于等级1。研究发现，2D与3D输入方式间存在显著差异：在复杂度最高的试次（等级3）中，二者耗时相差88.3秒（p=0.001）；在复杂度略低的试次（等级2）中，耗时相差71.8秒（p<0.001）。
