A heuristic evaluation is a usability inspection method for computer software that helps to identify usability problems in the user interface design. It specifically involves evaluators examining the interface and judging its compliance with recognized usability principles (the " heuristics ").
Nielsen founded the usability engineering movement for efficient and affordable improvements of user interfaces and he has invented several usability methods, including heuristic evaluation. He holds more than a thousand United States patents, [ 11 ] [ 12 ] mainly on ways of improving usability for technology.
A cognitive walkthrough is task-specific, whereas heuristic evaluation takes a holistic view to catch problems not caught by this and other usability inspection methods. The method is rooted in the notion that users typically prefer to learn a system by using it to accomplish tasks, rather than, for example, studying a manual.
Heuristic evaluation is a usability engineering method for finding and assessing usability problems in a user interface design as part of an iterative design process. It involves having a small set of evaluators examining the interface and using recognized usability principles (the "heuristics").
The heuristic-systematic model of information processing (HSM) is a widely recognized [citation needed] model by Shelly Chaiken that attempts to explain how people receive and process persuasive messages. [1] The model states that individuals can process messages in one of two ways: heuristically or systematically. Systematic processing entails ...
Usability inspection is the name for a set of methods where an evaluator inspects a user interface.This is in contrast to usability testing where the usability of the interface is evaluated by testing it on real users.
A heuristic device is used when an entity X exists to enable understanding of, or knowledge concerning, some other entity Y. A good example is a model that, as it is never identical with what it models, is a heuristic device to enable understanding of what it models. Stories, metaphors, etc., can also be termed heuristic in this sense.
A heuristic evaluation or usability audit is an evaluation of an interface by one or more human factors experts. Evaluators measure the usability, efficiency, and effectiveness of the interface based on usability principles, such as the 10 usability heuristics originally defined by Jakob Nielsen in 1994.
