Definition : Fitts’ Law

Fitts’ Law is a fundamental principle in human-computer interaction that describes the relationship between the size and distance of a target and the time it takes to reach and accurately select that target. It states that the time required to move to a target is directly proportional to the distance to the target and inversely proportional to the size of the target. In simpler terms, the larger and closer a target is, the faster and more accurately it can be selected. This law is often used in the design of user interfaces to optimize the placement and size of buttons, icons, and other interactive elements for efficient and accurate user interaction.
