User experience describes how people feel when navigating a website, using a mobile app or otherwise interacting with a company's digital products or services. There are many elements that contribute to designing for exceptional user experiences, such as user interface, usability and user research. However, user experience design does not equal user experience. It sounds redundant, but UX is what people actually experience, not the separate elements that UX professionals bring together to influence the experience. Optimizing and refining the elements of UX design can affect how the end user feels to a great extent, but there will always be some things that are out of the designer’s control.
Though there is no reason why user experience can’t apply to physical interactions, the term is usually reserved for interactions with digital technology. This is evidenced in the way that UX methodologies focus on areas like wireframing, usability and other digital-specific processes.
