Today I read a paper titled “Let Us Dance Just a Little Bit More — On the Information Capacity of the Human Motor System”
The abstract is:
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 such as dance and sports
The proposed new measure is based on a subject’s ability to accurately reproduce a complex movement pattern
We demonstrate our framework using motion-capture data from professional dance performances
