Technique F97:Failure due to locking the orientation to landscape or portrait view
About this Technique
This technique relates to 1.3.4: Orientation (Failure).
Description
The objective of this technique is to describe how restricting the view of content to a single orientation is a failure to allow content to be viewed in multiple orientations. When content is presented with a restriction to a specific orientation, users must orient their devices to view the content in the orientation that the author imposed. Some users have their devices mounted in a fixed orientation (e.g. on the arm of a power wheelchair), and if the content cannot be viewed in that orientation it creates problems for the user.
If a specific orientation is determined to be essential for the operation and viewing of the content, then this failure technique will not apply.
Examples
- A news app always shows the content in portrait orientation. Users can view the content on a device which supports landscape and portrait display orientations. When the device is turned to landscape view, the content appears sideways to the user.
Tests
Procedure
- Open the content in landscape view. Check that the content is oriented for this view.
- Open the content in portrait view. Check that the content is oriented for this view.
- Check if portrait or landscape view is essential for the viewing and operation of the content.
- If there are any controls in the content, user agent, operating system, or device that restrict or allow orientation changes, check that the controls can be set to allow checks #1 and #2 to be true.
Expected Results
- If check #1 or check #2 is false, and checks #3 and #4 are false, then this failure condition applies and content fails the Success Criterion.
