User experience designUser experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a company, its services, and its products. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance.
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.
Application (informatique)Une application, un applicatif ou encore une appli, une app est, dans le domaine informatique, un programme (ou un ensemble logiciel) directement utilisé pour réaliser une tâche, ou un ensemble de tâches élémentaires d'un même domaine ou formant un tout. Typiquement, un éditeur de texte, un navigateur web, un lecteur multimédia, un jeu vidéo, sont des applications. Les applications s'exécutent en utilisant les services du système d'exploitation pour utiliser les ressources matérielles.
Génie logicielLe génie logiciel, l'ingénierie logicielle ou l'ingénierie du logiciel (en software engineering) est une science de génie industriel qui étudie les méthodes de travail et les bonnes pratiques des ingénieurs qui développent des logiciels. Le génie logiciel s'intéresse en particulier aux procédures systématiques qui permettent d'arriver à ce que des logiciels de grande taille correspondent aux attentes du client, soient fiables, aient un coût d'entretien réduit et de bonnes performances tout en respectant les délais et les coûts de construction.
Heuristic evaluationA 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"). These evaluation methods are now widely taught and practiced in the new media sector, where user interfaces are often designed in a short space of time on a budget that may restrict the amount of money available to provide for other types of interface testing.
