See-Through Head Worn Display (HWD) Architectures

Abstract

Over the past 3 decades, as computer and display technology advanced along the path laid out by Moore's Law of miniaturization and functionality, many writers presented scenarios for augmented reality (AR) displays centered on bringing information to the individual. In that the emphasis was on the individual experience, the initial technology that did not pursue a see-through geometry seemed viable. When the initial solutions, a generation of look-at displays resting on the nose bridge appeared around 2000, the market did not embrace it. Suddenly now, social media has burst on the scene and wireless access has become ubiquitous. The result is a renewed research interest in a family of see-through head-worn displays (HWDs) enabling real-time interaction throughout the global community.
