UploadVR has an interesting story on a new prototype created by Facebook’s VR research division which replaces the traditional, totally bulky virtual reality headset with something closer to the sunglasses form factor we've been wanting since Snowcrash:
Facebook Reality Labs’ new approach is a thin film where focusing is done by holographic optics instead of by the bulk of the lens. "Hologram" in this context just means a physical “recording” of how light interacts with an object- in this case a lens rather than a scene.
Facebook claims the research may be able “to deliver a field of view comparable to today’s VR headsets using only a thin film for a thickness of less than 9 mm.” The total weight of the display module is claimed as just 18 grams.
But is this approach viable? I put that question to a colleague who happens to be one of the world's top experts in AR/VR technology (and so prefers to remain anonymous). They read Facebook's research paper associated with this prototype, and came back with this assessment:
"I think the tech is cool and the research is good for longterm innovation but is likely years away from a product. I think the Panasonic and other pancake optics is a bit closer."
What's holding Facebook's approach back?
Here's the deep dive from my expert, citing the research paper:
