This week the folks at Epic Games have debuted their first documentary series for the virtual reality environment. Not IN the virtual reality realm, but about it. In service to virtual reality, this series of videos will show the world what virtual reality is all about. The first episode goes by the name "A Sense of Presence: What is Virtual Reality?" and attempts to answer just that - in a very short span of time. One of the most major doors VR still needs to unlock for most people is a simple understanding of what this technology is - this video attempts to be the first key.
