Application of experiential locus of control to understand users' judgments toward useful experience

Recently, innovative products and services have been changing the way people live their lives. Human-computer interaction (HCI) plays an important role in the development and design of such products and services. However, prior studies did not fully explain how people evaluate their experience when they use a product and service. The research goal of this study is to propose a conceptual model that explains the judgment of experience quality and the judgment criteria. This study suggested two research questions: First, how can we understand users' judgment of good experience? We will suggest a theoretical model that is based on the concept of locus of control (LoC) for explaining users' evaluation of their experience, including the use result and the use process. Second, what are the representative system factors to affect users' judgment? This study validates the representative system factors that affect the determinants through verifying the conceptual model. Through a pre-study, the representative system features affecting each determinant were derived and hypothesized for the main study. The results showed that experiential LoC was affected both internally and externally by the two determinants. In addition, each of the determinants was affected by the dimension or level of the system features.
