Action cannot be performed with a screen reader turned on

Rule

Functionality MUST be available using screen reader touch methods (e.g. click actions), unless the functionality cannot be accomplished in any known way using a touch device.

Background

When you turn on a screen reader on a touch device, the screen reader disables any scripted gestures on a web page because the screen reader itself relies on gestures to function. On iOS devices, for example, swiping to the right moves the screen reader focus to the next element, and swiping to the left moves the screen reader focus to the previous element. Swiping up and down on iOS devices invokes other screen reader behaviors. If a web page relies on swiping actions, those actions will not work when the screen reader is turned on.

How to Fix

Fix this issue by ensuring that there are alternative methods to perform all gesture-based actions, for example: previous and next arrow buttons to advance a carousel in addition to swiping left and right.
