High Quality Content by WIKIPEDIA articles! Keystroke-level model, sometimes referred to as KLM or KLM-GOMS, is an approach to human–computer interaction (HCI), based on CMN-GOMS, developed by Card, Moran, and Newell, and explained in their book The Psychology of Human-Computer Interaction, 1983. The model is an 11-step method that can be used by individuals or companies seeking ways to estimate the time it takes to complete simple data input tasks using a computer and mouse. By using KLM-GOMS, individuals often find more efficient or better ways to complete a task simply by analyzing the steps required in the process and rearranging or eliminating unneeded steps.
