Facebook Reveals Sunglasses-Like Prototype VR Headset

Facebook is trying to make VR glasses thinner and additional “socially suitable.” The company in a new investigate paper has unveiled its glasses-like prototype virtual actuality (VR) headset with a display measuring 8.9mm in thickness, which is about the exact same as a standard smartphone. The social media huge states that 1 way to achieve “sun shades”-like VR headsets, is by changing the refractive lens with holographic optics. It fundamentally means that the new optics will allow the light to get to human eyes in a scaled-down distance, compared with normal VR gear that need to be cumbersome to accommodate thick lens to adjust the angle of mild from the show to our eyes.

The new optics will further assistance to retain the sort aspect and bodyweight of the VR headset a lot lighter, the Fb exploration paper highlights. The results are defined in the research paper led by Fb Reality Labs. The scientists note that to obtain slender, lightweight, and high-functionality close to-eye displays for virtual actuality, they have blended “holographic optics, directional backlighting, laser illumination, and polarization-centered optical folding.”

“Present [VR] headsets even now have box-like sort things and offer only a portion of the resolution of the human eye. Rising optical style and design tactics, these types of as polarization-based mostly optical folding, or ‘pancake’ optics, promise to improve functionality when reducing dimension.” the investigation notes.

Pancake optics effectively bounce gentle again and forth within a lens before achieving the human eyes. This successfully improves the distance in between the screen panel and focusing optic without escalating actual physical dimension. The research states that it makes it possible for the concentrating optics to be placed bodily near to the display panel, “whilst pretty much acting as if they were being substantially further more absent, providing a remarkable advantage in compactness.”

Limitations of the slim near-eye VR headset

The researchers pointed out that there are numerous constraints with the sun shades-like prototype VR headset, consequently indicating its launch is still many years absent. Currently, the prototype outputs in monochrome, and it is nonetheless to attain a whole-color display screen.

Similarly, the headset will have to address troubles like battery existence, device connections, and so on.

Fb-owned Oculus VR in 2019 launched Oculus Rift S virtual truth headset for $399 (about Rs. 30,100).
