An Evaluation of One-handed Techniques for Multiple-target Selection

摘要

Recent research has revealed that a large population of mobile users usually use one hand when interacting with mobile devices. However, very few techniques have been developed to support multiple-target selection. In this paper, we introduce Burst and ZoomTap, two techniques that aim to facilitate accurate and fast multiple-target acquisition with one-handed thumb operation on touch-based mobile devices. We compare our two techniques to Shift in a controlled experiment. The results show that for multiple-target selection, Burst and ZoomTap can outperform Shift; also according to the questionnaire, participants prefer Burst and ZoomTap to Shift.
