User experience (UX) is the overall experience of a person using a product, service, or system. It is a measure of how well the product or service meets the user’s needs and expectations, and of the user’s satisfaction with it. User experience is a multidimensional concept that includes factors such as usability, accessibility, and emotional response. It is an important consideration in the design of products and services, as it can affect their success and adoption. User experience is often evaluated through user research, which involves collecting feedback and data from users to understand their needs, preferences, and experiences. This information can be used to inform the design and development of products and services.
