TSI explores Glanceable Interfaces for XR technologies which are compact, enabling minimal information at a glance to avoid clutter, occlusion, and distraction. This is significant for ensuring safety in work areas minimizing the risk of accidents. AR digital elements normally occupy a large portion of the available visible space, therefore, obstruction of the visual field is dangerous. TSI works on novel, gaze-activated LOD XR UIs that initially launch with a compact interface and progressively expand to reveal more information in each LOD, with minimal real-world occlusion.
