目标选择任务中视觉反馈对笔倾斜输入的影响

Influence of Visual Feedbacks on Pen Tilt Input in Target Selection Tasks

考察了不同类型的视觉反馈对笔倾斜输入性能的影响。针对全图形反馈、部分图形反馈、数字反馈和无反馈4种不同的视觉反馈方式设计实验,测试通过用户倾斜笔来分别选择5°、10°和20°角宽度的扇形目标时的时间和错误率。实验结果表明在提供视觉反馈时会提高实验者选择扇形目标的速度和准确度,全图形反馈呈现出最好的性能。基于实验的结果,讨论了笔倾斜交互技术的设计方法,提出了一些可能的笔倾斜输入技术应用场景。研究结论对基于使用笔倾斜用户交互界面设计具有帮助和指导作用。

The influence of different visual feedback on pen tilt input performance was investigated. Full-track graphical visual feedback （FVF）, partial-track graphicl visual feedback, digital visual feedback, and no-track visual feedback were designed. Comparative experiments were con- ducted to explore the selection time and the error rate in target slection tasks that users tilt the pen to select 5°, 10° and 20° fan-shaped targets. Results show that visual feedback promoted the performance of speed and sccuracy,and FVF presented the best performance. Based on the experimental results,design methoods of pen tilt interaction technique were discussed and a series of possible pen tilt input application scenarios were proposed. The findings provide favor and guidance for pen tilt interface design.
