ABSTRACT
Fitts law is a fundamental tool in measuring the capacity of the human motor system. However, it is, by definition, limited to aimed movements toward spatially expanded targets. We revisit its information-theoretic basis with the goal of generalizing it into unconstrained trained movement. The proposed new measure is based on a subject’s ability to accurately reproduce a complex movement pattern. Possible applications outside human-computer interaction include sports science and clinical diagnosis.
