Fb is attempting to make VR glasses thinner and extra “socially acceptable.” The corporate in a brand new analysis paper has revealed its glasses-like prototype digital actuality (VR) headset with a show measuring 8.9mm in thickness, which is about the identical as an everyday smartphone. The social media big says that one approach to obtain “sun shades”-like VR headsets, is by changing the refractive lens with holographic optics. It primarily signifies that the brand new optics will permit the sunshine to achieve human eyes in a smaller distance, not like common VR gear that require to be cumbersome to accommodate thick lens to vary the angle of sunshine from the show to our eyes.
The brand new optics will additional assist to maintain the shape issue and weight of the VR headset a lot lighter, the Fb analysis paper highlights. The findings are defined within the analysis paper led by Fb Actuality Labs. The researchers word that to attain skinny, light-weight, and high-performance near-eye shows for digital actuality, they’ve mixed “holographic optics, directional backlighting, laser illumination, and polarization-based optical folding.”
“Present [VR] headsets nonetheless have box-like type elements and supply solely a fraction of the decision of the human eye. Rising optical design strategies, comparable to polarization-based optical folding, or ‘pancake’ optics, promise to enhance efficiency whereas decreasing measurement.” the analysis notes.
Pancake optics primarily bounce mild backwards and forwards inside a lens earlier than reaching the human eyes. This successfully will increase the gap between the show panel and focusing optic with out rising bodily measurement. The analysis states that it permits the focusing optics to be positioned bodily near the show panel, “whereas nearly performing as in the event that they have been a lot additional away, offering an amazing benefit in compactness.”
Limitations of the skinny near-eye VR headset
The researchers identified that there are a number of limitations with the sunglasses-like prototype VR headset, due to this fact indicating its launch continues to be years away. Presently, the prototype outputs in monochrome, and it’s but to attain a full-colour show.
Equally, the headset must handle challenges like battery life, system connections, and so forth.
Fb-owned Oculus VR in 2019 launched Oculus Rift S digital actuality headset for $399 (roughly Rs. 30,100).
