“User Experience” is a term first introduced by Don Norman in 1993. He used this term as a replacement for “user-centered design” which was often mistakenly perceived as only encompassing “human-computer interaction” and “usability.” Don Norman aimed to use this term to “encompass all aspects of people’s experience with a system, including industrial design, graphics, interface, and physical and manual interactions.” Fundamentally, “user experience” emerged as a result of the shift in enterprise product development and management towards a “user-centered” approach, driven by the rapid advancement of technology. Through “user experience,” innovators can address user mental blockages encountered during the innovation process. Therefore, “user experience” essentially refers to using design to assist users in making correct decisions. “User experience design” is the process in which product (or service) developers identify and reconstruct users’ “mental models.” They employ design to help users attain specific value and avoid decision-making errors. Today, “user experience” is regarded as an interdisciplinary field, with its foundation rooted in psychology. It is essentially an applied psychology based on “design.” It is closely intertwined with business, sociology, management, and encompasses various disciplines such as psychology, user research, behavioral design, information architecture, interaction design, user testing, product development, service design, team consensus, and business design.
