Abstract

LightSpace Technologies have developed a prototype of integrated head-mounted stereoscopic display system based on a proprietary multi-plane optical diffuser technology. The system is entirely solid-state and has six focal planes which covers ~3 diopters (from 32 cm to 8 m). For the operation no eye-tracking is utilized. The new display system virtually entirely eliminates vergence-accommodation conflict and adds a monocular accommodation as an important depth cue for improved 3D realism. In regards to content rendering the processing load in contrast to conventional single-focalplane stereoscopic displays with similar image resolution is only slightly increased. The differences in terms of comparative performance are the worst in the case of simple 3D scenes, while for high-complexity scenes this difference has a tendency to slightly decrease. On average the processing burden for multi-plane stereoscopic displays is no more than 1.5% higher than for conventional stereoscopic displays. Furthermore, increasing a number of physical focal planes doesn’t notably worsen the image rendering performance allowing the display device to be efficiently driven by already readily available hardware – including high-performance mobile platforms. Overall, the user feedback about the developed multi-plane stereoscopic 3D display prototype confirms prior proposed assumptions of multi-plane architecture yielding higher acceptance rate due to improved 3D realism and eradicated vergence-accommodation conflict, thus currently being one of the most noteworthy advancements in the field of 3D stereoscopic displays.
