Automatic Interface Design Testing Application: Case Study Mobile Chat Room Interface for Elderly

There are many researches who wants to conduct research on interface design. However, they face several obstacles such as limited knowledge and understanding in design or programming. To overcome such obstacle, the researchers developed an application which helps to test user interface design, from design creation to storing test results (i.e. time and steps needed to perform tasks, total errors) needed to analyze the design. This research uses mobile chat room interface as its case study. This automatic interface design testing application was implemented on Android platform and was developed using Flutter programming language. This research aims to know application's effectiveness according to users' needs and was measured using System Usability Scale (SUS). Respondents are lecturers who have conducted or often conducts research on usability, user interface, and user experience. The result shows that this application suits users' needs with good SUS score, illustrating that users can easily interact with this application.
