Explore by Touch

A screen reader interaction mode on touchscreen devices in which users drag their finger across the screen to discover and hear descriptions of interface elements beneath their fingertip. When Explore by Touch is active, a single tap does not activate a control — instead, the screen reader announces the element's label, role, and state. To activate the focused element, the user performs a double-tap anywhere on the screen. This mode is used by both TalkBack (Android) and VoiceOver (iOS) and is the primary way blind users navigate touchscreen interfaces. It effectively converts a visual-spatial interface into a tactile-auditory one, though it makes interaction inherently sequential since users must discover elements one at a time rather than seeing them all simultaneously.
