Our investigation aims to develop a quantitative human performance model of making single-stroke pen gestures within certain error constraints in terms of production time. Such a model will be useful as a foundation for the design and evaluation of existing and future gesture-based user interfaces at the basic motor control efficiency level, similar to the role of previous “laws of action” played to pointing, crossing or steering-based user interfaces. We report and discuss our experimental results on establishing and validating the model, together with other basic empirical findings in stroke gesture production.
