Donald Norman was working on interface designs for Apple in 1995 when he coined the term user experience.
User Experience, or UX, is defined as a person’s overall experience when using a product such as a website, computer application or a device. The UX is especially relevant in terms of how easy or pleasing it is to use.
The term UX became more widely known in the 1990s, dovetailing with related disciplines such as usability (Nielsen, 2001), interaction design (Verplank, 1980) and information architecture (Wurman, 1976).
Jakob Nielsen (2001), defines usability as a measurement of how easy web interfaces and websites are to use, making interactions with content easy, comfortable and secure. Usability is determined by technology and design and factors such as whether it is understandable, novel or attractive.
Richard Saul Wurman created the term information architecture in 1976. Information architecture is a concept used, in its broadest form, to express the design, organization and distribution of computer systems. Wurman explored the structure of information, including information anxiety, information architects, and information design.
