2.5.4 Motion Actuation

WCAG says:

Functionality that can be operated by device motion or user motion can also be operated by user interface components and responding to the motion can be disabled to prevent accidental actuation, except when:

• Supported Interface: The motion is used to operate functionality through an accessibility supported interface;

• Essential: The motion is essential for the function and doing so would invalidate the activity.

When this is applicable

When something gets triggered through motion.

Check for motion alternatives

Use a mobile device that has a motion sensor. Shake the device, move it physically around in multiple dimensions and move your hand around in front of the device.

If any functionality is triggered, check:

• it can also be triggered using a common alternative method, for example arrow buttons to move around in a game with a keyboard
• motion input can be deactivated (deactivation in the system settings is fine)

Exceptions:

• if motion is essential to the functionality
