Invited Session IV: Extended reality--applications in vision science and beyond: Improving augmented reality through perceptual science

Augmented reality (AR) systems make it possible to present visual stimuli that intermix and interact with people's view of the natural world. But building an AR system that merges stimuli with our natural visual experience is hard. AR systems often suffer from technical and visual limitations, such as small eyeboxes, limited brightness, and narrow visual field coverage. An integral part of AR system development, therefore, is perceptual research that improves our understanding of when and why these limitations matter. I will describe a suite of perceptual studies designed to provide guidance for engineers on the visibility and appearance of wearable optical see-through AR displays. Our results highlight the idiosyncrasies of how our visual system integrates information from the two eyes, the multifaceted nature of perceptual phenomena in AR, and the trade-offs that are currently necessary to create an AR system that is both wearable and compelling.
