+## Accessibility
+
+### Screen Readers
+
+Picker supports navigation using a screen reader by implementing the [`slider` role](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/slider_role) on each [Picker Column](./picker-column). The following gestures can be used to navigate the Picker.
+
+| Gesture | Function |
+| - | - |
+| Swipe Left | Move focus to the previous Picker Column. |
+| Swipe Right | Move focus to the next Picker Column. |
+| Swipe Up | Select the next option in the Picker Column. |
+| Swipe Down | Select the previous option in the Picker Column. |
+| Double Tap and Slide Up/Down | Adjust the selected option in the Picker Column. Can be used as an alternative to swiping up and down. |
+
+:::caution
+The Swipe Up and Swipe Down gestures rely on the correct key events being synthesized as noted on the [`slider` documentation](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Roles/slider_role). [Chromium-based browsers do not synthesize keyboard events correctly](https://issues.chromium.org/issues/40816094), but the "Double Tap and Slide Up/Down" gesture can be used as an alternative until this has been implemented in Chromium-based browsers.
