From Usability to User Experience

Usability and user experience (UX) are considered as key quality determinants of any product, system or service intended for human use, which in turn can be considered as product, system or service success or failure indicators. At the same time, people regularly get confused between the two terms usability and user experience because they are strongly related to each other. In this paper, we first present a collection of usability and user experience definitions from previous studies. Then we provide a survey of different viewpoints about the interrelated relationship between them with the aim to answer the following questions: "Is User Experience part of Usability satisfaction?" or "Is Usability a part of User Experience?"
