User Experience (UX) is everything that happens to a user while interacting with a product, service or general experience. This includes the person’s emotions, attitudes, reactions and behavior during the experience.

As a design field, UXBeginner defines user experience at three levels:

Level 1 (broadest): the general experience anyone can have with a product or service.
Level 2 (as philosophy): Placing the user – and their experience – as the priority and origin of truth for product design.
Level 3 (as a way of doing things): UX leverages design thinking, processes, tools and techniques (wireframes, sitemaps) in order to create and affect the user’s experience.
