笔方位及与笔倾斜的混合输入

Pen Azimuth and Hybrid Input with Pen Tilt

针对传统笔式设备输入能力有限的问题,引入笔方位并考查其性能及其与笔倾斜的混合使用.首先设计笔方位目标选择和笔方位与笔倾斜混合目标选择2个实验;然后采用组内重复方法展开实验,考查笔方位及其与笔倾斜混合输入的性能.实验结果表明,正方向的笔方位输入优于斜方向;30°,60°和90°笔方位容限划分下,分别形成了6个、4个和1个速度一致区间;笔方位和笔倾斜划分越密集,用户完成目标选择任务的难度越大;当笔方位容限区间为60°且笔倾斜容限区间为20°时达到最优的划分.最后给出笔方位与笔倾斜混合使用的建议和应用场景,为基于方位和倾斜的笔式交互技术设计提供了参考依据.

Aiming at the limited input capability of traditional pen,pen azimuth was introduced and its performance and hybrid use with pen tilt were investigated.First,two experiments of pen azimuth target selection and pen azimuth+pen tilt target selection were designed.Then experiments were carried out to investigate the performance of pen azimuth and the hybrid input with pen tilt.The experimental results showed that pen azimuth input in axial directions was better than in oblique directions.6,4 and 1 speed-consistent-intervals were formed under 30,60 and 90 degrees pen azimuth tolerances,respectively.The narrower the interval,the more difficult it was for users to perform the target selection tasks.When the pen azimuth tolerance was 60 degrees and the pen tilt tolerance was 20 degrees,the optimum discretization was gotten.Finally,the suggestions and application scenarios of the hybrid use of pen azimuth and pen tilt were given.The conclusions provide a reference for pen interaction design based on azimuth and tilt.
