Here's my understanding of it: `accelerationIncludingGravity` is supposed to represent [_"the acceleration of the hosting device, plus an acceleration equal and opposite to the acceleration due to gravity"_](https://w3c.github.io/deviceorientation/#ref-for-dom-devicemotionevent-accelerationincludinggravity%E2%91%A3), so if the device is lying flat on a horizontal surface, the host device's acceleration is 0, gravity is -9.8 and therefore `accelerationIncludingGravity.z` is 9.8. In example 8, it's `acceleration.z` that is -9.8, while `accelerationIncludingGravity.z` would be -9.8 from `acceleration.z` + 9.8 of an acceleration equal and opposite to the acceleration due to gravity = 0. -- GitHub Notification of comment by rakuco Please view or discuss this issue at https://github.com/w3c/deviceorientation/issues/96#issuecomment-875606800 using your GitHub account -- Sent via github-notify-ml as configured in https://github.com/w3c/github-notify-ml-config
