8.27 WCAG 2.1 Success Criterion 2.5.1 – Pointer Gestures

Complex gestures, such as swiping, dragging a slider or two-finger pinching for zooming, can be performed through simpler actions like taps or long presses.

Before Rectification

A webpage sample with a sliding bar only to adjust the volume.

The dragging of a slider requires a precise path of the user's pointer movement to control the volume.

After Rectification

A webpage sample with a sliding bar and two buttons to adjust the volume.

Buttons are added as an alternative way for users to adjust the volume with simple clicks.
