Integration Strategies of Pen Interaction and Touch Interaction

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. © 2019, Beijing China Science Journal Publishing Co.
