Facebook’s latest VR headset looks like a pair of sunglasses

Facebook has shown a headset for the virtual reality of the new proof conceptAnd it has a completely different design than most other VR devices on the market today. Instead of a huge mess that covers the upper half of your face and should be wrapped around your head, this proof headset is like a pair of large sunglasses that can sit comfortably on your ears.

Facebook is still charging this new device not as a pair of reality glasses, as the general idea of ​​AR devices goes, but legal VR products. They are very thin, less than 9 mm thick. Here’s a look from top to bottom.

Towards the concept, the glasses don’t seem to look slim, but they obviously radiate images to your eyes in a way that sets them apart from the usual VR headphones on the market today. I will allow it Facebook research team Explain one of the techniques called “holographic optics”.

Many VR displays share common viewing optics. A simple refractive lens made of thick, corrugated cloth or glass or plastic. We suggest replacing this heavy element with holographic optics. You may be familiar with the holographic images on the scientific museum or on your credit card, which seem to be three-dimensional, with a realistic depth of the page or beyond. Like these holographic images, our holographic optics are the recording of the interaction of laser light with objects, but in this case the object is the lens, not the 3D scene. The result is a sharp decrease in thickness and weight. The holographic lens bends the light like a lens, but it looks like a thin, transparent label.

The headset also uses a technique Facebook calls “optical folding based on loading” to help reduce the real image of the space “between the lens of the image”. With optical folding based on loading, “light can be controlled to move both forward and backward through moving lenses so that this empty space passes multiple times, collapsing it into a portion of its original volume.”

These glasses are just proof, but it’s not clear if they will ever hit the market. “While this points to the further development of lightweight, comfortable and high-quality AR / VR technology, our work is currently purely research,” the Facebook research team wrote in a blog post.

Many companies revolve around the idea of ​​glasses like AR / VR headphones, which combine the best of the two technologies into one device, but it usually ends up as a bulkier VR’s central headset, which uses external camcorders to make the AR lighter. Intel and Microsoft, both of which use the term “mixed reality” to describe devices such as HoloLens, have been investing in the idea for some time.

But more companies are now working behind the scenes to make a smaller, truly hybrid device a reality. Apple has been working on this for years, and Google bought AR glasses today, an acquisition that could allow the company to revive the dream of a consumer-screen manager in the style of Google Glass.

While we can’t be sure that any of the tech giants will release the combined AR / VR glasses, the evidence of Facebook’s evidence may hint at what it might look like at some point in the future.
