The law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. … 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 … 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 have separate effects on movement time. … See more Fitts's law deals only with targets defined in space. However, a target can be defined purely on the time axis, which is called a temporal target. A blinking target or a target moving … 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 the target • final movement. Slower but more precise movement in order to acquire the target 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 paper with Peterson. With the adjustment, … 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 … See more
WebWhat is Fitts’ Law? Definition of Fitts’ Law: Based on Shannon’s theorem for information processing, Fitts’ law allows the estimation of required times for rapid movements between a starting point and a target area. Fitts introduced the index of difficulty (ID) as a characteristic measure for such movements. The ID is defined as: ID ... Web(5) This formula explains Fitts’ law (8,19), which states that the reaching time followsTr=p+ rlog2(2D/W), whereF:=log2(2D/W)is called the Fitts’ index of difficulty, andpandrare fixed constants.

WebOct 28, 2011 · Fitts' law is an empirical rule of thumb which predicts the time it takes people, under time pressure, to reach with some pointer a target of width W located at a distance D. It has been traditionally assumed that the predictor of movement time must be some mathematical transform of the quotient of D/W, called the index of difficulty (ID) of …
