DeviceMotionEvent: acceleration property

Secure context

The acceleration read-only property of the DeviceMotionEvent interface returns the acceleration recorded by the device, in meters per second squared (m/s²). This value does not include the effect of the gravitational force, in contrast to accelerationIncludingGravity.

[!NOTE] If the hardware does not know how to remove gravity from the acceleration data, this value may not be present in the DeviceMotionEvent. In this situation, you’ll need to use accelerationIncludingGravity instead.

Value

The acceleration property is an object providing information about acceleration on the three axes in the Device coordinate frame. Each axis is represented with its own property:

• x
  • : Represents the acceleration along the x axis
• y
  • : Represents the acceleration along the y axis
• z
  • : Represents the acceleration along the z axis
