A model of non-preferred hand mode switching
Jaime Ruiz, Andrea Bunt, Edward Lank · 2008
Effective mode-switching techniques provide users of tablet in-terfaces with access to a rich set of behaviors. While many re-searchers have studied the relative performance of mode-switching techniques in these interfaces, these metrics tell us little about the behavior of one technique in the absence of a competitor. Differing from past comparison-based research, this paper describes a tem-poral model of the behavior of a common mode switching tech-nique, non-preferred hand mode switching. Using the Hick-Hyman Law, we claim that the asymptotic cost of adding additional non-preferred hand modes to an interface is a logarithmic function of the number of modes. We validate the model experimentally, and show a strong correlation between experimental data and values predicted by the model. Implications of this research for the design of mode-based interfaces are highlighted. Index Terms: H5.2 [User Interfaces]: Interaction styles— 1
