Facebook VR headset prototype looks cool but it’s not ready
The prototype that Facebook is working on looks like a pair of oversized sunglasses. Instead of regular refractive optics, it uses something called holographic lenses. This technology allows light to bounce back and forth between the lens and the display, before reaching the eye, effectively fitting large focal lengths into a small space. The result is a much more compact device that is lightweight and comfortable to wear.
“The design is demonstrated in a proof-of-concept research device that uses only thin, flat films as optics to achieve a display thickness of less than 9 mm while supporting a field of view comparable to today’s consumer VR products,” reads part of the description on Facebook's research blog.
However, there’s a caveat. The prototype is far from ready. In its current form, Facebook’s VR glasses can only display green light images. The researchers will try to make a transition from their big desktop prototype (that can display full-color images) to the cool portable glasses, shown above. Let’s hope they succeed.
