In order to measure and predict user experience (UX) more accurately, researchers have proposed a variety of models to integrate various factors affecting user experience. However, the complexity of user experience research is due to the dynamically changing factors of user and environment. The user expectation is not only affected by social communication and media, but also formed by hisher previous experience of similar products. To study user experience in the temporal dimension, we must consider the dynamic nature of user expectation and take the interaction between user expectation and user experience into account. In this study, we first discuss the definition of user expectation, and then explore how the previous user experiences to existing products influence the present user expectation, and thereby affect the successive user experience on a new design.
