Non-Visual Exploration

The process by which blind or visually impaired people gather information about their physical environment, documents, or interfaces without relying on sight. Non-visual exploration combines multiple strategies including touch, audio feedback, spatial memory, contextual knowledge, and interactive scanning with assistive technology. In digital accessibility, non-visual exploration techniques include touchscreen gestures (as in VoiceOver's Explore by Touch), cursor-based interactions using phone cameras and computer vision, and audio descriptions of visual scenes. Effective non-visual exploration tools must support both overview understanding (what is in a space) and targeted focus (details about a specific item), as these serve different user needs.
