          Abstract

          Multi-touch gestures embedded in touch-based interfaces and devices present challenges. It can be difficult for users to discover different gestures and understand their effects. The study reported in this paper hypothesises that presenting automatic visual prompts, termed self-previewing gestures (SPGs) in this research, that depict touch and preview gesture execution will mitigate the problems that users encounter with unfamiliar gestural interfaces. A within-subjects experiment (n=45) is reported in which an iPad application with two alternative gestural designs, and five alternative user interface versions (one industry, two research baselines, and two SPGs) was created with the purpose of making the available gestures evident. A rating system that adapts Norman’s Theory of Action to touch-based interactions by making use of known principles within interaction design (perceptible affordances, feedforward and feedback) is proposed. The system was used to assess participants’ perceptions of and interactions with the SPGs, and the results revealed positive and negative aspects of designs and UI versions.
