It was initially developed by Paul Fitts. See more Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human–computer interaction and ergonomics. The law predicts that the time required to rapidly move to a target area is a … See more A movement during a single Fitts's law task can be split into two phases: • initial movement. A fast but imprecise movement towards … See more An important improvement to Fitts's law was proposed by Crossman in 1956 (see Welford, 1968, pp. 147–148) and used by Fitts in his 1964 … See more Extensions to two or more dimensions In its original form, Fitts's law is meant to apply only to one-dimensional tasks. However, the original experiments required subjects to move a stylus (in three dimensions) between two metal plates on a table, … See more The original 1954 paper by Paul Morris Fitts proposed a metric to quantify the difficulty of a target selection task. The metric was based on an information analogy, where the distance to the center of the target (D) is like a signal and the tolerance or width … See more The formulation of Fitts's index of difficulty most frequently used in the human–computer interaction community is called the Shannon … See more Not long after the original model was proposed, a 2-factor variation was proposed under the intuition that target distance and width … See more canon eos rebel xsi software download
