Touch-to-Explore

An interaction mode used by touchscreen screen readers (such as VoiceOver on iOS and TalkBack on Android) where users drag their finger across the screen to discover and hear descriptions of interface elements beneath their fingertip. As the user's finger passes over buttons, icons, text, or other elements, the screen reader announces each item, allowing blind and visually impaired users to build a mental map of the screen layout. Once a desired element is located, the user typically double-taps anywhere on the screen to activate it. Touch-to-explore fundamentally changes the touchscreen interaction model from direct visual targeting to an audio-guided exploration process, and research has identified several common exploration strategies including zigzag scanning, border-first searching, and direct pointing.
