Paper Abstract

Anplar fields of view filling at least the region directly viewable on the optical axis of the eyes -about 90 - are necessary to support the illusion of being immersed in another space, be it computer generated or the product of remote cameras. Any greater view, up to 270° laterally, enhances the illusion. Stereopsis, and completing the 360° visual sphere by head motion, round out the illusion; they require the wearing of a head-mounted-display (HMD). This paper describes the optical viewing system used in almost all existing HMD systems, and makes the case that, compared to video monitors, these HMD systems provide a qualitatively different kind of access to remote or computer generated reality -a difference that, even in the present crude state of the art, is striking enough to herald a new order of computer interfacing and real time telepresence. A caveat is presented: that if the spatial presentation is false - not "orthospace" - then the charm and power of the illusion, and the utility of the system, are sharply diminished.
