针对单手情况下笔的输入能力有限、触控输入精确度低且存在手指遮挡等问题,为了发挥笔和触控各自的优势,提出面向惯用手的笔+触控输入技术.首先设计和展开目标装入实验,分析了笔和触控输入的性能特点.然后结合绘图场景,提出顺序法、交叠法和并行法3种面向惯用手的笔+触控混合输入技术,以及用作对比的按钮法参考技术,并通过实验考察了4种输入技术的性能,结果表明,笔在小目标操作的精度和速度上优于触控;相比于按钮法,交叠法在操作时间和轨迹偏移量方面分别减少了15.9％和0.2％;并行法在时间和偏移量方面分别增加了25.6％和40.5％;顺序法在操作时间方面增加了11.2％,但是在偏移量方面减少了12.8％.最后给出了各种不同混合输入技术的应用场景,对面向惯用手的笔+触控交互和用户界面设计具有指导意义.%Limit capacity for pen input, low accuracy and finger occlusion for touch input exist in single-handed input situations. To take advantage of pen and touch input, pen + touch input techniques were proposed to im-prove the dominant-handed input. First, a target docking experiment was designed and carried out to analyze the characteristics of pen and touch inputs. Then, 3 pen + touch input techniques, which were Sequence, Overlap and Parallel, were proposed in drawing scenario. Moreover, Button-click was also proposed as a reference technique for comparison. Comparative experiment was conducted to investigate the performance of the 4 techniques. Re-sults showed that, for small targets, pen performed better than touch on accuracy and speed. Compared to But-ton-click, Overlap reduced the operation time and trajectory offset by 15.9％ and 0.2％; Parallel increased the op-eration time and trajectory offset by 25.6％ and 40.5％ respectively; Sequence increased the operation time by 11.2％, but reduced the trajectory offset by 12.8％. Finally, the application scenarios of these techniques were given, which is instructive to dominant-handed pen + touch interaction and user interface design.
