Fitts 2 applied Shannon's information theory to the human motor system and proposed an empirical model that relates movement duration to movement distance and target width, called Fitts' law, based on the following . Fitts' Law is modulated by movement history | SpringerLink The first thing to note about Fitts' Law is that it is an equation that calculates something called the Index of Difficulty. Your request did not contain a Referrer header. For example, to find a given word (e.g. with JavaScript and. am i performing this equation wrong? Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human-computer interaction and ergonomics. The speed/accuracy trade-off in simple aiming movements. A Deep Dive Into Fitts' Law - Tim Marco 6. Calculate kinematics of body movement from the set of spatial coordinates. Eye tracking is a common user study technique, . 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. This is the raw formula: MT=a + b * log2 (D/W + 1) MT is the movement time it takes to move between two spots, which is what we're trying to figure out. Speed-accuracy tradeoff in Fitts' law tasks—on ... - ScienceDirect You can use Fitts to compare input devices, such as mouse versus an alternative to a mouse, by . See also Errors, Fitts' Law, Progressive Disclosure, and Wayfinding. Fitts's law - Wikipedia Fitts' law | Article about Fitts' law by The Free Dictionary Much of the work using Fitts' Law to assess 2-D tasks has been pioneered by MacKenzie [64]- [70], who has demonstrated the utility of using this "model by analogy" to empirically evaluate user . Fitts' law states that it takes more time to hit a target if the target is further away and it also takes more time if the target is smaller. For instance, 0.5cm_X_2cm would mean that the ribbons were 0.5cm wide, and 2cm apart. This later became known as Fitts's law [Fitts 1954]. As it is clear that an infinite small target is Fitts' Law and Infinite Width - Coding Horror
