Fitts law formula explained
WebFitts’ Law states that there exists a linear relationship between task difficulty and movement time (response time). Task difficulty is determined by calculating the index of difficulty, which is specified by the distance (amplitude) between targets and the width of the target. WebThe first thing to note about Fitts' Law is that it is an equation that calculates something called the Index of Difficulty. Index of Difficulty Index of Difficulty = = log 2 log 2 ( ( Width Width Distance Distance +1 +1)) This is a unitless number that is used to describe how difficult it is for users to point at something.
