Virtual reality technologies are significant for medical applications. Canon's magnetic resonance imaging (MRI) system, “Vantage Galan 3T,” focused on patient comfort. The MRI head‐up display (MRI‐HUD) system was also provided as “MR Theater” for this purpose. MRI‐HUD is based on Head Dome Projector (HDP). HDP is a head‐mounted display consisting of a dome‐shaped screen and a mobile LED projector with an ultra‐wide projection lens. HDP was created to demonstrate that non‐flat plane images provide a superior hyper‐realistic impression. In the development process of HDP, we carried out subjective evaluation to confirm the effects of elimination of the flat plane for a hyper‐realistic impression. And we confirmed that the images on the dome screen provide a better impression than the images on a cylindrical screen or a flat screen. MRI‐HUD is a head‐up display system that uses HDP as a real image source. A dome screen and a reflection mirror composed of non‐magnetic materials are constructed beside the patient's bed in the MRI gantry. MRI‐HUD creates wide field‐of‐view images that eliminate the feeling of limited space of the MRI gantry from the beginning to end of the examination.

“…In this work, the development of the research on the hyperrealistic display was advanced. 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]. Based on these results, depth perception enhancement through monocular vision was used for the development of a new-concept HUD.…”

Described 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.

“…We thus find that monocular vision affects the reinforcement of space perception and that the reinforcement of the stereoscopic sense is 0.5-1.3 points higher than for binocular vision (see Figure 1). 3,4 We have therefore used these depth perception monocular vision enhancement results to develop a new monocular HUD concept, which we call the windshieldrefracted augmented reality projector (WARP). In this system (see Figure 2), the display image can be set to any depth position and thus represents an improvement over conventional approaches.…”
