What are some of the more important performance parameters to consider when purchasing a VR display?
Depending on the application, the most common capability parameters include resolution and color depth, field-of-view, and brightness and/or contrast. Some lesser known but equally important specifications include the exit pupil and eye relief. A large exit pupil provides a large sweet-spot, making it easier for the user to move their eyes and head without losing the image, and a large eye relief accommodates eyeglasses without clipping or vignetting the virtual image.
