Abstract
The present invention teaches a method of constructing head-mounted virtual display apparatuses for mobile activities based on a non-cross-cavity optical configuration, which simultaneously provides the user with “look toward” access to an inset virtual image and an unobstructed forward field of view of at least 35 degrees. In one embodiment, a pair of light deflecting elements and associated adjustment means project a light path from the normal peripheral field of view towards the eye without geometric distortion of the virtual image associated image plane tilt.
