NotiFade: Minimizing OHMD notification distractions using fading

Abstract: While animations can be used to minimize attention costs for desktop notifications, their application for Optical see-through Head-Mounted Display (OHMD) notifications is underexplored. To investigate the effectiveness of animation on OHMD notifications in minimizing attention costs, we conducted a study comparing fade-in, blast, and scrolling notification animations. Results showed that fade-in animation minimizes interference to the primary task, unlike blast and scrolling animations. Its effectiveness depends on multiple factors, including fade-duration, location and complexity of the primary task. Finally, we discuss how fade-in animation can improve OHMD notifications and its associated trade-offs.
