Integrated head-mounted display system based on a multi planar architecture

摘要

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