Abstract
The majority of applications for head mounted display (HMD) users, irrespective of whether they are for short-term, long-term, low vision, augmented reality, etc. yield a conflicting set of tradeoffs between user comfort and minimal fatigue and strain during use, ease of attachment, minimizing intrusiveness and aesthetics which must be concurrently balanced with and are often in conflict with providing an optical vision system that provides the user with a wide field of view and high image resolution whilst also offering a large exit pupil for eye placement with sufficient eye clearance. Further, individual users' needs vary as do their needs with the general task at-hand, visual focus, and various regions-of-interest within their field of view. To address these issues, it is necessary to provide a high performance optical system, eyepiece design, and system features which overcome these limitations.
