8.20 WCAG 2.2 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  

Adjust the volume by dragging a slider necessitates a precise path of the user's pointer movement. Persons with disabilities, who may type with a finger or use specialised input devices such as eye gaze devices, might find it difficult or unable to perform these actions effectively.

After Rectification  

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