An exploration of pen tail gestures for interactions

In this paper, we performed an exploration on the design and evaluation of pen tail gesture, an interaction method that allows the use of pen tail movement to initiate interactions. Based on our interviews with some designers and researchers who regularly used pen-based tools, we conducted three experiments to establish baseline criteria to distinguish intentional pen tail gestures from incidental pen tail movements, and to understand the basic movement behaviors in pen tail gestures. We developed designs and recognition methods of pen gestures, and implemented three application prototypes based on them. Our research can inspire some new designs of pen-based tools and enrich the design repertoire of pen-based user interfaces.

► This paper explores the design of pen tail gesture for pen-based user interaction.
► Criteria to distinguish intentional and incidental pen tail gestures are established.
► Design rules to reduce pen tip movement caused by pen tail gestures are provided.
► Pen tail gestures for common user tasks and their recognition methods are developed.
