| Background Designers have made effort to help users obtain knowledge for operating a product so that they can achieve a result quickly and easily. This research, however, assumed that user experience could be affected not only by skillful operations of a product/system, but also by knowledge for problem-solving in the task domain. This paper particularly sought to analyze how user experience could be different according to user`s domain knowledge level. This paper, then, presented some insights for UI design.
Methods Two case domains were chosen, equalizing domain of music player app and photo-taking domain of camera app. For each, 2 case applications were chosen according to how much the UI design delivers domain knowledge. To conduct comparative observations, the participants were divided into two groups, Novice and Expert, according to their domain knowledge levels. After observations, task times, satisfaction, and overall experiences of using their domain knowledge in the process were analyzed.
Result From the analyses, it was found that there were differences in the satisfaction and behaviors between domain Novice and Expert users. For instance, Novices preferred UI that did not much present domain knowledge, providing simple operations, while Experts preferred UI that delivered domain knowledge, allowing them to control the factors for quality results. Also, the two groups showed different in knowledge-applying behaviors.
Conclusion This result shows that UX/UI designers need to consider users` domain knowledge since user experience can be affected by their knowledge for solving problems in the domain as well as their knowledge for operating a system. |
