【摘要】：针对笔倾斜输入过程中存在遮挡、视角错觉和缺乏反馈等问题,分析了视觉反馈的增加对笔倾斜输入性能的影响.首先结合笔倾斜的特点设计了图形全跟踪、图形部分跟踪、图形无跟踪、数字全跟踪、数字部分跟踪和数字无跟踪6种不同的笔倾斜视觉反馈;然后通过对比实验考察了经过视觉反馈后,在直接和间接设备上完成不同角间距的目标选择任务时笔倾斜输入的性能.实验结果表明,视觉反馈可以有效地提升目标选择的速度,而跟踪机制可以有效地提高目标选择的准确度;图形反馈的速度快于数字反馈;全跟踪反馈的错误率低于部分跟踪反馈;在直接设备上完成目标选择任务速度快,但在间接设备上完成目标选择任务的准确度更高.最后给出了笔倾斜输入和视觉反馈的使用原则和建议,对笔式界面中的笔倾斜交互和视觉反馈设计具有指导意义.
[Abstract]:Aiming at the problems such as occlusion, angle illusion and lack of feedback in the process of pen tilt input, the effect of the increase of visual feedback on the performance of pen tilt input is analyzed. Firstly, six kinds of visual feedback of pen tilt are designed according to the characteristics of pen tilt, such as graphic full tracking, graph partial tracking, graph without tracking, digital total tracking, digital partial tracking and digital no tracking. Then, the performance of pen tilt input in the target selection task with different angular spacing on the direct and indirect equipment after visual feedback is investigated by contrast experiment. Experimental results show that visual feedback can effectively improve the speed of target selection, and tracking mechanism can effectively improve the accuracy of target selection, graphics feedback is faster than digital feedback. The error rate of total tracking feedback is lower than that of partial tracking feedback, and the speed of completing target selection task on direct equipment is faster, but the accuracy of completing target selection task on indirect equipment is higher. Finally, the principles and suggestions of the pen tilt input and visual feedback are given, which can guide the design of the pen tilt interaction and visual feedback in the pen interface.
