Facebook appears to now support 360-degree videos as it launches a special tie in with Star Wars: The Force Awakens to show off the new functionality.
360-degree videos are becoming more common as we head towards an expected future of widespread use of VR, thanks to gadgets like the Samsung Gear VR and the Oculus Rift (which, not coincidentally, is owned by Facebook). If you check out the video (follow the link to see the video, as it is non embeddable beyond the Facebook page) on a normal web browser, though it plays like a normal video notice how you can click and drag around, to point the camera in a direction of your choice.
The video itself is was created by LucasFilm's ILM X Lab and sits the viewer inside a speeder on the Jakku desert. Perhaps most notably, it features the same crashed Imperial Star Destroyer that got everyone so excited in the first Force Awakens trailer.
Presumably we can expect Facebook to roll this functionality out further shortly, so that Rift owners will have plenty to watch when the device officially goes on general sale next year.
