Evaluating The Usability of Massive Open Online Course User Interface Based on Eye-Tracker Data

Massive Open Online Course (MOOC) is a learning platform widely used today, especially since the Covid-19 pandemic. MOOC allows someone to gain knowledge from various universities around the world quickly. MOOCs have become a popular source for seeking knowledge because the costs are relatively cheap. The number of users is quite large worldwide, so a universal user interface (UI) is essential for a MOOC because different backgrounds and cultures can cause people to have different ways of interacting with interfaces. MOOCs should have good UX when used by people from various regions. To measure the UX of an UI, we can use several metrics, one of which is behavioral metrics. This research examines user behavior towards several types of MOOC layouts with the help of an eye tracker to measure user behavior when interacting with MOOC. Test results show that users only pay attention to the first appeared content when they did not have any goals yet. However, if the user understands their goals, UI appearance variations only slightly impact user behavior. Therefore, in MOOCs, important content should be located in the center of the screen, both vertically and horizontally. Apart from that, content considered the most important must appear first compared to other content.
