useDeviceMotion

Reactive DeviceMotionEvent. Provide web developers with information about the speed of changes for the device's position and orientation.

Usage

import { useDeviceMotion } from '@vueuse/core';

const { acceleration, accelerationIncludingGravity, rotationRate, interval } = useDeviceMotion();

Note: For iOS, you need to use trigger and bind it with user interaction. After permission granted, the API will run automatically

State	Type	Description
acceleration	object	An object giving the acceleration of the device on the three axis X, Y and Z.
accelerationIncludingGravity	object	An object giving the acceleration of the device on the three axis X, Y and Z with the effect of gravity.
rotationRate	object	An object giving the rate of change of the device's orientation on the three orientation axis alpha, beta and gamma.
interval	Number	A number representing the interval of time, in milliseconds, at which data is obtained from the device..
ensurePermissions	boolean	Indicates whether the platform requires permission to use the API
permissionGranted	boolean	Indicates whether the user has granted permission. The default is always false
trigger	Promise<void>	An async function to request user permission. The API runs automatically once permission is granted

You can find more information about the state on the MDN.
