The User Experience effect of Applying Floating Action Button (FAB) into Augmented Reality Anatomy Cranium Media Learning Prototype

A learning media's success is determined by two factors, namely the instructional design and user interface design. Most of the existing AR anatomy-based teaching media still do not pay attention to the learning media's UI and UX design. Elements such as navigation menus, text, icons, buttons, and others still accumulate, leading to the interface feel dense. This problem also can shift the user's attention when using this learning media. We tried to apply the FAB (Floating Action Button) to high-fidelity AR-based anatomy learning media prototype to overcome this. In this study, the FAB functions are as navigation and the main action of the prototype. We chose the FAB as a primary action and navigation since its ability to attract user attention and expand and narrow itself. FAB is recommended as navigation if the user needs to access certain parts or application functionality quickly regardless of hierarchy and limited navigation space. To find out the effect of user experience on FAB in this AR-based teaching media. Researchers use UEQ (User Experience Questionnaire). The results of the research show that the prototype using FAB produces three scales at the “above average” level, two scales at the “Good” level, and one scale is at the “excellent” level. Overall, the resulting scale shows pretty good results.
