When you consider the features of a virtual reality headset, what can you look for? Field of view, lightweight design and high res are at the very best of all users requirements. The virtual reality headset (often abbreviated HMD for Head Mounted Display) fits, obviously, on the head, much like sunglasses or a visor. It will have either one small display lens to cover one eye, or two to cover both eyes. The lenses will display in 3D sun and rain of the virtual reality environment. In this headset, there are two types of vision models: the kinds with and without a tracking system. Minus the tracking system, you might see the same image in the headset, whichever way one's head is turned. A (HMD)with a tracking system is sophisticated enough to make note of the angle and position of the head and adjust the virtual image accordingly. Eye tracking technology is used to note where in fact the user is looking and bring that area into better focus. That is why, the average inter-pupillary distance in humans can be used to coordinate the eye trackers in the virtual reality headset. Some VR headsets are designed to show some type of computer generated image or a real-world view from somewhere else. Some are sophisticated enough to overlay a CGI display over a genuine world view. This is called the optical see-through version. The field of view that humans naturally experience is really a good deal smaller in the virtual reality headset. Humans have a field of view, expressed in degrees, of 180. So, the greater the field of view of a typical virtual reality headset, the more in depth the image will be. However, as most people aren't really alert to what, say, a 25 degree FOV will be like, manufacturers and merchandisers will most likely make reference to the FOV of confirmed model of virtual reality headset in terms that folks do understand. It will be quoted because the size of a monitor or television screen. The higher the field of view, the better the sense of immersion in to the VR environment. A narrow field of view eliminates peripheral vision and can not render a satisfactory experience. And what about the resolution of a virtual reality headset? As with computers monitors, this figure is again quoted in computer terms, i.e., in pixels. A VR headset might be said to have an answer of, say, 1920 X 1600 pixels. As for pixel density, between 10-20 pixel per degree is good. The bigger the number, the higher pixel density for resolution in the virtual reality headset. (HMD)s are advanced enough, now, to be run by the average home computer, given that it is equipped with an electrical graphics card.
