Final answer:
The Keystroke Level Model evaluates the time required to perform user interactions with a computer system by breaking down tasks into elementary actions, which do not include solely cognitive workload, typing speed, mouse movements, or eye-tracking.
Step-by-step explanation:
The Keystroke Level Model (KLM) is a method used for estimating how long it takes for a person to accomplish routine tasks without errors using a human-computer interface. The KLM focuses on assessing the time it takes to complete tasks based on the theory that user interactions can be broken down into a sequence of elementary actions, such as keystrokes, mouse movements, and system responses. Importantly, the KLM does not measure cognitive workload, analyze typing speed only, evaluate mouse movements exclusively, or focus on eye-tracking. Its purpose is broader; it seeks to provide a practical and straightforward way to evaluate the efficiency of user interactions with a computer system, by measuring the time taken to perform sequences of these elementary actions.
