摘　　要：针对笔输入能力弱和触摸输入精度低的问题,提出笔式交互与触摸交互的融合策略,并设计了笔+触摸输入技术.首先定性考察笔输入和触摸输入的特性和优劣势,提出2种笔+触摸输入的融合策略;其次基于融合策略设计3种笔+触摸输入技术以及用于参照对比的单笔和单触摸输入技术;再通过3个实验比较这些输入技术的性能.实验结果表明,与单笔或单触摸相比,在颜色改变的直线轨迹任务中,笔+单指触摸、笔+多指触摸和笔+触摸手势的性能分别提升至少90.909%,80.165%和148.209%;在颜色和粗细均改变的圆形轨迹任务中,笔+触摸和笔+手势的任务完成时间比单笔分别减少16.552%和19.705%,而错误率不存在显著差异;在颜色和粗细均改变的绘画任务中,笔+单指触摸、笔+多指触摸和笔+触摸手势的综合指标分别为5.933,3.333和4.700.最后给出面向笔+触摸输入的交互设计建议、应用场景和改进思路,对笔和触摸的混合输入与界面设计具有指导意义.Aiming at the weak ability of pen input and the low precision of touch input,this paper puts forward the integration strategies of pen interaction and touch interaction and designs pen+touch input technologies.First,the characteristics and advantages of touch input and pen input were qualitatively investigated and two integration strategies of pen+touch input were proposed.Second,three pen+touch input technologies and pen-only and touch-only input technologies for reference were designed.Third,their performances were explored through three experiments.The experimental results showed that the performance of pen+uni-finger touch,pen+multi-finger touch and pen+touch gesture were improved at least 90.909%,80.165%and 148.209%respectively compared with the performance of pen-only or touch-only in color-change straight-line trajectory tasks.The task completion time of pen+touch and pen+gesture were 16.552%and 19.705%less than that of pen-only respectively in color-thickness-change circular trajectory tasks,and there was no significant difference in error rate.The general indexes of pen+uni-finger touch,pen+multi-finger touch and pen+touch gesture were 5.933,3.333 and 4.700,respectively in color-thickness-change drawing tasks.Finally,the interactive design suggestions,application scenarios and improvement ideas for pen+touch input were given,which provide guidelines for pen+touch interactive technique and interface design.
