Design Space for Finger Gestures with Hand-held Tablets

摘要

This paper presents research how a finger-gesture design space for interacting with hand-held tablets may be defined. The parameters that limit or extend this space, such as anatomy-dependent gesture feasibility, grasp requirement, gesture occlusion or complexity, are discussed based on initial explorative expert interviews and following user studies. The goal of this research is defining parameters that have to be taken into account for developing a finger-gesture UI model for hand-held tablets. Although this model has a strong user-centric design approach, rather than being technology driven, technical solutions for detecting finger gestures are also considered. A model design is presented and research questions for investigating this model in greater detail are outlined.
