Study on user-interface problem-finding based on flow-line analysis

Abstract

A user interface is one an essential component that determines the efficacy of computer software. Therefore, evaluating and improving a user interface are crucial aspects of the software development process. User interfaces have been improved through various methods, including user testing and heuristic approaches. However, these techniques cannot be applied practically because the data provided by them may contain subjective aspects and do not reveal the developer’s demands. Therefore, to develop practical methods required in this field, we interviewed the developers on site to understand their needs. With this information, we developed a technique and conducted an experiment. In the process, we successfully analysed and illustrated the problems in a user interface by using flow line analysis techniques to obtain a user’s software-usage history. Finally, by applying the technique to experimental software interface and interviewing the developers, we verified that the new method provided the necessary information.
