User-centered design (UCD) or user-driven development (UDD) is a framework of processes in which usability goals, user characteristics, environment, tasks and workflow of a product, service or brand are given extensive attention at each stage of the design process.
User experience design is a user centered design approach because it considers the user's experience when using a product or platform. [2] Research, data analysis, and test results drive design decisions in UX design rather than aesthetic preferences and opinions, for which is known as UX Design Research.
In 1986, Norman introduced the term "user-centered design" in the book User Centered System Design: New Perspectives on Human-computer Interaction [22], a book edited by him and by Stephen W. Draper. In the introduction of the book, the idea that designers should aim their efforts at the people who will use the system is introduced:
Contextual design (CD) is a user-centered design process developed by Hugh Beyer and Karen Holtzblatt. It incorporates ethnographic methods for gathering data relevant to the product via field studies, rationalizing workflows , and designing human–computer interfaces .
In the user-centered design paradigm, the product is designed with its intended users in mind at all times. In the user-driven or participatory design paradigm, some of the users become actual or de facto members of the design team. [6] The term user friendly is often used as a synonym for usable, though it may also refer to accessibility ...
Human-centered design has its origins at the intersection of numerous fields including engineering, psychology, anthropology and the arts. As an approach to creative problem-solving in technical and business fields its origins are often traced to the founding of the Stanford University design program in 1958 by Professor John E. Arnold who first proposed the idea that engineering design should ...
user-centered design of human-machine interaction and human-computer interaction (HCI); design of information technology systems that support cognitive tasks (e.g., cognitive artifacts); development of training programs; work redesign to manage cognitive workload and increase human reliability. designed to be "easy to use" and accessible by ...
Usability goals must be included in every product design process that intends to follow a Human Factors approach (for instance, User-centered design [1] process or Usability Engineering Lifecycle [5] [full citation needed]). They have to be clearly stated from the onset of the process, as soon as the end-users needs, risk of use, contexts and ...
