“In recent years, user experience design has become a popular topic in the web design community, with discussions focussing on successful examples of good UX design. With regard to websites, the term covers all aspects of a user’s experience within a particular site. In other words, the visual layout, information architecture, usability, graphics, user interaction: everything. User interface design and HCI, or Human Computer Interaction are both included in UX. UX design has its roots in the late 1940s as machines become both more complex and more prevalent in daily life, but it was in the 1990s that the concept of user experience design was named and popularized in relation to computer use. It is a multi-disciplinary field, covering aspects of sociology, psychology, graphic and industrial design, and cognitive science.”
