WebPaul Fitts found a predictable relationship between the size of a target, the distance we have to move to it, and the speed at which we can tap, point at, click, or whatever on it. Today we'll do experiments to try to determine this relationship. The typical Fitts' Law experiment involves WebFitts’ (1954) original experiment used a reciprocal tapping task where the subjects tapped back and forth between two rectangular targets. The width of the targets and the …

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 law … 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 … 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 WebFitts’ law Fitts’ law experiment proposed to use a standard task to measure motoric skills. It states that the average time needed to select the target is linearly related to the index-of-difficulty (ID). This means you select the target with width (W) positioned at a distance (D) form the current position.

Fitts' law was found to be applicable, but had R 2 lower than for younger subjects. On average, it took elder participants twice as much time to complete movement tasks, but their accuracy was two times higher.

The premise for this is twofold: 1. Throughput cannot be calculated on a single trial. 2. A sequence of trials is the smallest unit of action for which throughput can be attributed as a measure of performance.
