DeviceMotionEvent: rotationRate property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2023.

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

The rotationRate read-only property of the DeviceMotionEvent interface returns the rate at which the device is rotating around each of its axes in degrees per second.

Note: If the hardware isn't capable of providing this information, this property returns null.

Value

The rotationRate property is a read only object describing the rotation rates of the device around each of its axes:

alpha: The rate at which the device is rotating about its X axis; that is, front to back.
beta: The rate at which the device is rotating about its Y axis; that is, side to side.
gamma: The rate at which the device is rotating about its Z axis; that is, being twisted about a line perpendicular to the screen.
