Test utilisateurUn test utilisateur, ou test d’utilisabilité, est une méthode permettant d'évaluer un produit en le faisant tester par des utilisateurs. Le plus souvent, il s'agit de produits du domaine informatique (par exemple : un logiciel ou un site web) dans le cadre de l'intervention ergonomique. Elle est considérée comme une démarche indispensable dans la conception de produit, car la plus efficace pour évaluer l'ergonomie d'une application ou d'un site web.
Iterative designIterative design is a design methodology based on a cyclic process of prototyping, testing, analyzing, and refining a product or process. Based on the results of testing the most recent iteration of a design, changes and refinements are made. This process is intended to ultimately improve the quality and functionality of a design. In iterative design, interaction with the designed system is used as a form of research for informing and evolving a project, as successive versions, or iterations of a design are implemented.
Ergonomie des interfaces informatiquesL'ergonomie informatique (ou ergonomie des interfaces) est une branche de l'ergonomie, qui a pour objectif d'améliorer les interactions homme-machine, la facilité d’utilisation et d’apprentissage des produits interactifs. Cette pratique cherche à concevoir ou modifier des interfaces afin qu'elles soient en adéquation avec les caractéristiques physiologiques, perceptives et cognitives de leurs utilisateurs potentiels. Elle s'appuie sur différentes méthodes de conception et d’évaluation permettant d’obtenir le logiciel ou le site web le mieux adapté aux utilisateurs visés.
User interface designUser interface (UI) design or user interface engineering is the design of user interfaces for machines and software, such as computers, home appliances, mobile devices, and other electronic devices, with the focus on maximizing usability and the user experience. In computer or software design, user interface (UI) design primarily focuses on information architecture. It is the process of building interfaces that clearly communicates to the user what's important. UI design refers to graphical user interfaces and other forms of interface design.
Component-based usability testingComponent-based usability testing (CBUT) is a testing approach which aims at empirically testing the usability of an interaction component. The latter is defined as an elementary unit of an interactive system, on which behavior-based evaluation is possible. For this, a component needs to have an independent, and by the user perceivable and controllable state, such as a radio button, a slider or a whole word processor application. The CBUT approach can be regarded as part of component-based software engineering branch of software engineering.
