Ensure content does not rely solely on device movement
Functionality that relies on device motion should also be operable through other user interface components. Allow users to disable motion-based controls to avoid accidental activation, except in specific cases where motion is essential for the function.
Acceptance Criteria
• Functionality operable by device motion must also be operable through a non-motion-based interface.
• Users must be able to disable motion-based interactions to prevent accidental activation, unless:
• Supported Interface: The motion-based functionality is supported by an accessible interface.
• Essential: The motion-based functionality is crucial and cannot be replaced by another method without affecting the activity’s purpose.
Examples
• A game that can be controlled by tilting a phone also allows control through on-screen buttons.
• A fitness app that uses device tilt to track movement also offers a manual input option.
Exceptions
• When the motion is used in a way that is essential for the functionality and disabling it would invalidate the purpose of the interaction.
Tips
• Consider offering an alternative control method for all motion-based interactions.
• Provide clear instructions for users on how to disable or switch motion-based controls.
How to test?
• Test the application or site to ensure that all motion-based interactions can be operated by alternative methods.
• Verify that users can disable motion-based interactions without losing access to essential functionality.
