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 ").
Jakob Nielsen pioneered the interface usability movement and created the "10 Usability Heuristics for User Interface Design." [ 9 ] Usability is aimed at defining an interface’s quality when considering ease of use; an interface with low usability will burden a user and hinder them from achieving their goals, resulting in the dismissal of the ...
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 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. [8]
Parts 3 to 9 deal with physical characteristics of computer equipment. Part 110 and parts 11 to 19 deal with usability aspects of software, including Part 110 (a general set of usability heuristics for the design of different types of dialogue) and Part 11 (general guidance on the specification and measurement of usability).
The dimensions can be used to evaluate the usability of an existing information artifact, or as heuristics to guide the design of a new one, and are useful in Human-Computer Interaction design. [4] Cognitive dimensions are designed to provide a lightweight approach to analyse the quality of a design, rather than an in-depth, detailed description.
A usability study may be conducted as a primary job function by a usability analyst or as a secondary job function by designers, technical writers, marketing personnel, and others. It is widely used in consumer electronics , communication , and knowledge transfer objects (such as a cookbook, a document or online help ) and mechanical objects ...
Usability inspection methods are generally considered to be less costly to implement than testing on users. [1] Usability inspection methods include: Cognitive walkthrough (task-specific) Pluralistic walkthrough; Heuristic evaluation (general), or (domain or culture-specific) [2] Action Analysis; Guideline scoring or testing [3]
