DeviceMotionEvent

Baseline 2023

Newly available

Since September 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The DeviceMotionEvent interface of the Device Orientation Events provides web developers with information about the speed of changes for the device's position and orientation.

Warning: Currently, Firefox and Chrome do not handle the coordinates the same way. Take care about this while using them.
