What is User Experience?
We all have used products and services that make us happy and delight us; and we all have used products and services that make us feel stupid and frustrate us. User Experience is the set of tools and disciplines that help us create better user experiences. Many roles contributes to the user experience of what we use: UI designers, user experience researchers, front-end developers, product managers, and more.
User experience emphasizes people’s perceptions and emotions rather than (just) efficiency and task completion, which were the focus of traditional usability and human factors. Traditional usability concepts such as ease of use and ease of learning are still important, but other aspects of the users experience– beauty, playfulness, engagement, delight–are now center stage when creating stuff that people use
