360-degree videos are typically viewed via personal computers, mobile devices such as smartphones, or dedicated head-mounted displays. Users can pan around the video by clicking and dragging. On smartphones, internal sensors such as the gyroscope can also be used to pan the video based on the orientation of the device. Taking advantage of this behavior, stereoscope-style enclosures for smartphones (such as Google Cardboard viewers and the Samsung Gear VR) can be used to view 360-degree videos in an immersive format similar to virtual reality. The phone display is viewed through lenses contained within the enclosure, as opposed to virtual reality headsets that contain their own dedicated displays.
