User Experience Design (UXD, UED, or XD) is the process of manipulating user behavior through usability, accessibility, and desirability provided in the interaction with a product. User experience design encompasses traditional human–computer interaction (HCI) design and extends it by addressing all aspects of a product or service as perceived by users. Experience design (XD) is the practice of designing products, processes, services, events, omnichannel journeys, and environments with a focus placed on the quality of the user experience and culturally relevant solutions.
