When you consider the specialties of a virtual reality headset, what do you look for? Field of view, lightweight design and high resolution are at the top of most users needs.
It will have either one small display lens to cover one eye, or two to cover both eyes. The lenses will display in 3D the elements of the virtual reality environment.
Eye tracking technology is used to note where the user is looking and bring that area into better focus. For this reason, the average inter-pupillary distance in humans is used to synchronize the eye trackers in the virtual reality headset.
Astoria virtual reality headsets are designed to show a computer generated image or a real-world view from somewhere else. Some are stylish enough to overlay a CGI display over a real world view. This is called the optical see-through version.
The field of view that humans naturally experience is a whole lot smaller in the virtual reality headset.So, the greater the field of view of a typical virtual reality headset, the more in depth the image will be.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 a resolution of, say, 1920 X 1600 pixels. As for pixel density, between 10-20 pixels per degree is good. The higher the number, the better pixel density for resolution in the virtual reality headset.
