Abstract :
Fitts´ (1954) law has been used since the early 1950s to characterize the traditional speed-accuracy tradeoffs associated with pointing and/or neuromotor tasks. It provides a paradigm to investigate how a human´s control action can be reproduced by simple first-order models of the arm/hand motion. Such a simple human performance paradigm provides valuable insight into how arm motion can be characterized by engineers in certain analysis scenarios. This paper presents a derivation of Fitts´ law using basic control theory
