Facebook and Oculus have ventured to create compact and more comfortable VR headsets, and their most recent experiment is pretty close to the optimal: easy-to-wear displays as good as a pair of shades. Facebook’s Reality Labs has managed to develop a working evidence of their conceptualized device. For the optics, it employ sholographic with flat films, creating displays lesser than 0.35 inches wide — significantly smaller than the currently used LCD or OLED shining through glass. This is also assisted by optical folding based on polarization.
Facebook has already brought prototypes of comparatively larger and more complicated Oculus VR headsets, and has made its attraction towards creating more advanced units fairly public. The model was first talked about in the Siggraph 2020 research paper called “Holographic Optics for Thin and Lightweight Virtual Reality”.It formulated for lighter and thinner Virtual Reality headsets, and is expected to feature in “high performance AR/VR” devices of the future.
The “pancake optics” technique in corporates many layers of thin holographic film with a system of laser projection (much like the projectors that produce images on a screen) and directional backlights. This can deliver both flat imagery and 3-D holograms counting on the complexity of the design. Depending on the amount of color, lighting, and components of alignment intensification a modelhas, the thickness of the system will vary anywhere between below 9mm to 11mm.
The resolution of the prototype of the VR glasses may be compared to the Oculus Quest, that is, 1,200 by 1,600 pixels (16-inches by 21.3-inches), and a field of view that can either be a 93° circle or a 92×69° rectangle. The weight of the Oculus Quest is 571 grams or 1.26 pounds while the weight of this prototype is claimed to be less than 10gm, which can further be lowered to 6.6gm, but that would also lead to the production of images of lower quality. As an added advantage, the power of the processor is proposed in a separate device, which can possibly hang from the glasses with a cable.
Presently, the glasses are only a model proposed by Facebook and Oculus,and it is still unknown when the complete product will launch for sale in the market. Facebook also sells two VR headsets at present: Oculus Quest and Rift S. Acheap product, Oculus Go was called off from stores recently.
