User Experience Design (abbreviation UX, UXD) – A discipline focused on designing the end-to-end experience of a certain product. To design an experience means to plan and act upon a certain set of actions, which should result in a planned change in the behaviour of a target group (when interacting with a product).
You now know that UX is not about prototyping, is not about visual design, is not about research. UX is broader than that. User Experience is about the creation of efficient and pleasurable products based on knowledge about human behavior and emotions.
