The field of user experience represents an expansion and extension of the field of usability, to include the holistic perspective of how a person feels about using a system. The focus is on pleasure and value as well as on performance. The exact definition, framework, and elements of user experience are still evolving.
User experience of an interactive product or a website is usually measured by a number of methods, including questionnaires, focus groups, observed usability tests, user journey mapping and other methods.
