Sensors that are commonly capable of detecting DeviceMotionEvent include sensors in laptops to protect moving storage devices. It is different from the DeviceOrientationEvent because it is listening for changes in acceleration as opposed to orientation. The second event is the DeviceMotionEvent, which is sent when a change in acceleration was added. By receiving and processing the data reported by these orientation events, it's possible to interactively respond to rotation and elevation changes caused by the user moving the device. The first one is the DeviceOrientationEvent, which is sent when the accelerometer detects a change to the orientation of the device. There are two JavaScript events that handle orientation information. In particular, hand-held devices such as mobile phones can use this information to automatically rotate the display to remain upright, presenting a wide-screen view of the web content when the device is rotated so that its width is greater than its height. Increasingly, web-enabled devices are capable of determining their orientation that is, they can report data indicating changes to their orientation with relation to the pull of gravity.
