Paul M. Fitts

Paul M. Fitts was a psychologist known for studying human movement and ergonomics. He developed Fitts's Law, which predicts how long it takes a person to move quickly and accurately to a target, based on the distance to and size of the target. This principle helps designers create more efficient and user-friendly interfaces, such as computer controls and touchscreens, by understanding how humans perform precise movements. Fitts’s work bridges psychology and practical design, improving how we interact with technology and machinery.
