Orientation
Summary:
WCAG 1.3.4, "Orientation," aims to ensure that digital content is accessible and usable regardless of the device's screen orientation, whether portrait or landscape. This guideline enhances accessibility for users who may use their devices in a fixed orientation due to physical disabilities or personal preferences.
What:
This criterion stipulates that content should not restrict its view and operation to a single display orientation, such as landscape or portrait, unless a specific orientation is essential. Users should be able to access and interact with content in any orientation they choose or require.
Why:
Some users, especially those with physical disabilities, might have their devices mounted in a fixed orientation or find it easier to use in one orientation over another. Ensuring that content can be used in both portrait and landscape modes makes it more accessible to a broader range of users.
Examples and Scenarios:
- E-Reading Apps: An e-book app should be fully functional and legible in both landscape and portrait orientations to accommodate different user preferences and setups.
- Online Shopping: Websites for online shopping should be navigable and maintain functionality whether the user's device is in portrait or landscape mode.
- Mobile Games: Games on mobile platforms should be playable in both orientations unless the game's core mechanics require a specific orientation.
How to Comply:
- Websites: Design responsive websites that adapt content layout to both portrait and landscape orientations without losing functionality or readability.
- Mobile Apps: Ensure app UI and content are flexible and adapt to both landscape and portrait orientations.
- Software Applications: Test and adjust applications to ensure they work seamlessly in both orientations, especially on mobile devices or tablets.
Exceptions:
- Specific Functionality Requirements: Certain functions or content that intrinsically require a specific orientation, such as games or specific tools.
- Security or Safety Reasons: Certain tasks may require a fixed orientation for security or safety reasons.
