Motion actuation cannot be disabled.

Rule

For functionality that can be triggered by a) device motion (like shaking, tilting) or b) user gestures detected by device sensors (including a camera) both of the following MUST be true: 1) motion actuation can be disabled, and 2) the functionality can be operated without using device motion or user gestures. Exceptions exist.

Background

Some applications utilize device sensors that allow the user to control something or do something by changing the device orientation, moving the device in a particular way, gesturing near the device, etc. For example, shaking the device might issue an "Undo" command, or a gentle hand wave might be used to move forward or backward in a sequence of pages. People with motor disabilities may not able to use this functionality (either not at all, or not precisely enough) because the device is on a fixed mount (perhaps a wheelchair) or because of other dexterity impairments. All functionality that can be triggered by device sensors must be implemented in a way that additional accessible means of activation are also available. In addition, some users may accidentally activate sensors due to tremors or other motor disabilities. Users must also have the ability to turn off motion actuation to prevent such accidental triggering of functions. When alternative methods of actuation are provided and motion actuation can be disabled, people with motor disabilities will be able to successfully use that functionality.

How to Fix

Fix this issue by providing a mechanism, such an application setting, that turns off motion-actuated features.
