Abstract
If we can collect a large number of user-friendly user interface (UI) examples, it will lead to efficient UI design and the discovery of new UI design principles. However, since it is difficult for experts to collect examples based on users’ opinions on a large scale, an approach that directly solicits examples from citizens as users is conceivable. In this research, we thought it was necessary to create a platform to solicit user-friendly UI from citizens. However, there is a problem that users are generally unaware of the existence of user-friendly UIs. In order for users to become aware of the existence of user-friendly UIs, they need to know examples of user-friendly UIs and the basic concepts of user-friendly UIs. In this study, we taught these to 47 university students through lectures to make them quasi-experts and collected examples of user-friendly UI and shared them through a website. As a result, we were able to collect 100 reports of user-friendly UI from the students. We confirmed that people with specialized knowledge of user-friendly UI can find user-friendly UI and provide valid explanations. We also confirmed through questionnaires that their view of the product changed.
