user experience (UX) is the structured concept of how a human interacts with a system — the mental model, emotional response, and behavioral feedback loop formed through use. It carves the space of human-system encounters by parameters: the interface medium (physical, digital, service), the users prior knowledge, and the systems responsiveness. UX persists through design practice, usability testing, and the shared vocabulary of heuristics and patterns that disciplines like interaction design accumulate across products.
