WebThe Index of Difficulty (ID) that can be derived from Fitts' law demonstrates that the difficulty of a task can vary for the same amount of task Task complexity One of the current views of how we control prehension is that the transport and grasp phases function Synergistically Fitts's law is used to model the act of pointing, either by physically touching an object with a hand or finger, or virtually, by pointing to an object on a computer monitor using a pointing device. 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.
