Card, Moran, and Newell keystroke-level model

E874569

The Card, Moran, and Newell keystroke-level model is a predictive human–computer interaction framework that estimates expert user task completion times by decomposing actions into low-level operations like keystrokes, mouse movements, and mental preparation.
