1. Keystroke-level model

   In human–computer interaction, the keystroke-level model (KLM) predicts how long it will take an expert user to accomplish a routine task without errors using an interactive computer system. It was proposed by Stuart K. Card, Thomas P. Moran and Allen Newell in 1980 in the Communications of the ACM and published in their book The Psychology of Human-Computer Interaction in 1983, which is considered as a classic in the HCI field. The foundations were laid in 1974, when Card and Moran joined the Palo Alto Research Center (PARC) and created a group named Applied Information-Processing Psychology Project (AIP) with Newell as a consultant aiming to create an applied psychology of human-computer interaction. The keystroke-level model is still relevant today, which is shown by the recent research about mobile phones and touchscreens (see Adaptions).

1. Keystroke-level model

   Keystroke-level model, sometimes referred to as KLM or KLM-GOMS, is an approach to human–computer interaction, developed by David Kieras and based on CMN-GOMS. CMN-GOMS for its part was 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. It is designed to be easier to use than other GOMS methods, such that companies who cannot afford human–computer interaction specialists can use it. KLM-GOMS is usually applied in situations that require minimal amounts of work and interaction with a computer interface or software design. The calculations and the number of steps required to accurately compute the overall task time increase quickly as the number of tasks involved increases. Thus, KLM-GOMS is best suited to evaluate time specific tasks that require, on average, less than 5 minutes to complete.
