What gesture confirms an action or selects an item on a touch screen for screen readers?

In the context of touch screen interactions for screen readers, a double tap is the gesture that typically confirms an action or selects an item. This practice aligns with accessibility standards designed to accommodate users who rely on both touch and auditory feedback.

When utilizing a screen reader, a single tap generally serves to focus on an item or bring it into view, but does not execute an action. A double tap, on the other hand, indicates that the user wants to perform the action associated with the focused item, such as opening an application or selecting a menu option. It is a key gesture used in touch-based screen reader environments, ensuring that users can interact with content efficiently.

Other gestures mentioned, such as swipe left or swipe down, are usually intended for navigation through lists or moving through content rather than selecting or confirming a specific option. Thus, understanding the function of these gestures helps users navigate touch interfaces with accessibility tools effectively.
