WebJul 17, 2024 · The FITT principle stands for frequency, intensity, time and type of exercise. These are four components that we can consider when creating a training programme. The four components are interconnected and how we manipulate them within a training programme, will influence the outcome of that programme. WebFitts’ law is centered around a mathematical equation that is used to illustrate the time it takes to reach a target object. A target object, in the context of UIs, can be any …
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. WebFitts' law: that throughput is independent of the speed-accuracy tradeoff (aka cognitive set). As space is limited, we direct readers to other sources for detailed discussions on Fitts' law and the utility of throughput [3-5]. Additional work of note is Fitts and Radford's 1966 experiment, similar to ours, and with similar outcome.
