Pressing a Button You Cannot See: Evaluating Visual Designs to Assist Persons with Low Vision ...
summary
Smartglasses-based AR augmentations highlight touchscreen targets and show smartglasses-based AR augmentations that sit over buttons; a prototype runs on AR glasses and uses visual overlays. A user study with 16 participants finds 7 could not use the interface at all without support, and 4 more could interact when augmented. Augmentations significantly reduce task time for unfamiliar layouts, lower error rate for familiar layouts, and decrease NASA-TLX workload; no single overlay wins and limited AR field-of-view and personalization remain constraints.
