Pointer Gestures
Summary:
WCAG 2.5.1, "Pointer Gestures," focuses on ensuring that web content is accessible to users who cannot perform complex gestures. This criterion benefits users with motor disabilities or those using assistive technologies.
What:
It requires that all functionalities using multi-point or path-based gestures must be operable with a single pointer without a path-based gesture.
Why:
Complex gestures like pinching or swiping can be difficult for some users. Ensuring that these actions can be completed with simpler alternatives, like a single tap or click, makes content more accessible.
Examples and Scenarios:
- Image Galleries: Allow users to navigate through images with simple clicks instead of swiping.
- Maps: Enable map functions like zooming in or out with single clicks or buttons, not just pinch gestures.
- Interactive Games: Offer alternatives to multi-touch gestures for game interactions.
How to Comply:
- Websites and Mobile Apps: Provide alternatives to complex gestures. For example, use buttons or links as alternatives to swiping or dragging.
- Software Applications: Ensure that any functionality that typically requires complex gestures can also be operated with simple clicks or taps.
Exceptions:
- Essential Gestures: If a multi-point or path-based gesture is essential and cannot be replicated with a single pointer, it might be exempt. This should be rare and justified.
