Abstract
ABSTRACTDescribed in this paper is a novel hyperreality display called ‘head dome projector (HDP).’ HDP is a head-mounted display consisting of a dome-shaped screen with a very small radius (40 cm), a mobile projector with an ultra-wide projection lens, and light-emitting diode (LED) light sources. The principal feature of HDP is a very wide-viewing angle: 160° horizontally × 120° vertically, comparable to the human visual field, without head tracking, and 360 × 360° with head tracking. In the subjective evaluation and comparison of HDP with a flat-panel display (FPD), HDP achieved 2.5-points higher hyperreality than FPD in the case of a ±5-level evaluation for high-definition motion images. Also proposed herein is a novel hyperrealistic head-up display (HUD) concept, the windshield-refracted augmented reality projector (WARP), and described is the developed prototype WARP system. It uses monocular vision, which eliminates the depth cues caused by parallax information. The developed WARP system achieved free depth control of the HUD image position.

It was found that when a user faces the non-plane display of a wide visual field, monocular vision affects the reinforcement of the space perception and stereoscopic sense [10]
Summary
The audiovisual-experience automatic virtual environment [1] and CyberDome display [2] are well-known immersive hyperreality or virtual reality displays. To create a compact and wide-viewing hyperreality dome projector for personal use, taking advantage of the compactness and wide color gamut of LED light sources, a new-concept hyperreality HMD called ‘head dome projector (HDP)’ with a curved screen and a compact LED projector was developed [4]. It has a 115° horizontal and 80° vertical field of view (FOV). One observes a seethrough image through the reflected equipment (combiner) placed in front of the observer Such displays are used for aircraft and entered practical use for cars in the 1990s [8].
