摘要/Abstract

摘要： 越来越多的笔式设备通过增加笔倾斜输入来提高其输入能力。但在直接输入设备和间接输入设备上执行笔的倾斜操作时,由于操作环境和视觉反馈的不同,往往会导致操作性能产生差异。本研究以探索笔倾斜输入在直接设备和间接设备上的性能差异为目的,以实证手段考察在两种设备上获取不同角间距下的不同笔倾斜目标时的操作速度、稳定性和准确性,讨论导致直接设备和间接设备笔倾斜性能不同的原因,并提出适用的角间距和倾斜目标位置。实验结果表明,在直接设备和间接设备上操作笔倾斜角时,在操作速度上直接设备优于间接设备,但在稳定性和准确性上,间接设备优于直接设备。20°的角间距对两种设备来说都呈现较好的性能,若需要在更小角间距内完成目标选择操作,在间接设备上的效果更好。最后,对两种设备的用户使用习惯进行了总结,为基于笔倾斜角的用户界面设计提供了帮助和参考。

Abstract: More and more pen devices introduce tilting to expend the parallel input capacity.However,when using pen tilt on direct device and indirect device respectively,due to the diversities of operating environment and visual feedback,the performance of direct and indirect pen tilt input are often discrepant.Aiming at exploring the differences of pen tilt input performance on these two kinds of devices,we empirically investigated the speed,stability and accuracy of pen tilt input in target selection tasks according to different angle interval.We discussed the possible reasons why the performances of pen tilt input are different and suggested the optimal tilt angle interval and tilt target.Experimental results indicate that the human abilities to control pen tilt in direct and indirect input device are different.That users complete tilt selection tasks on direct devices is faster but less stable and accurate than on the indirect ones.20° tilt angle interval is the optimal interval for user to select both of devices,while the indirect one is better if smaller interval is given.Therefore,this study gave guidelines for pen interface designs in direct and indirect pen tilt conditions and presented user habits with these two kinds of devices as a reference.
