Abstract. The original KLM paper. Decomposes any error-free interactive task into a sequence of M (mental preparation), K (keystroke), P (pointing), B (button press), H (hand-homing), and W (waiting) operators, each with a calibrated unit time. The basis for every back-of-envelope predictive analysis of UI performance since.
