Cognitive Load & Information Processing
Fitts's Law
A predictive model of human movement stating that the time to acquire a target is a function of the distance to and size of the target.
Explained
- The time to hit a target depends on how big it is and how far away it sits.
- Large controls placed near the thumb are faster and less error-prone to reach.
- Small or distant targets slow people down and increase mis-taps.
- This is why primary actions belong in easy, reachable zones at a generous size.
