WebOne of the clear takeaways from Fitts' Law is that the Index of Difficulty is inversely proportional to the target Width. If you make targets larger and closer to the user, … WebPerhaps the most celebrated law of human motor control is Fitts’ law (Fitts, 1954). This law expresses a relation between the kinematic property of movement speed and the non … 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 function of the ratio between the distance to the target and the width of the target. Fitts's … Meer weergeven 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 … Meer weergeven The formulation of Fitts's index of difficulty most frequently used in the human–computer interaction community is called the Shannon formulation: This form … Meer weergeven Not long after the original model was proposed, a 2-factor variation was proposed under the intuition that target distance … Meer weergeven 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 … Meer weergeven 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. … Meer weergeven 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, target width (W) is replaced by an effective target width (We). We is … Meer weergeven Fitts's law deals only with targets defined in space.
