[ L ] Fitts' Law

Fitts' law is a robust model of human psychomotor behavior developed in 1954. The model is based on time and distance. It enables the prediction of human movement and human motion based on rapid, aimed movement, not drawing or writing.

It seems intuitive that movement time would be affected by the distance moved and the precision demanded by the size of the target to which one is moving. Fitts discovered that movement time was a logarithmic function of distance when target size was held constant, and that movement time was also a logarithmic function of target size when distance was held constant.
