INSUBCONTINENT EXCLUSIVE:
Authors: JordanWhen it comes to using a virtual reality (VR) headset, no matter how good the display is, what you see will always be limited
by how wide the headset's field of view. Most of the best VR headsets on the market, like the Oculus Rift, PlayStation VR and HTC Vive,
have a 110-degree field of view, which is actually pretty good, but you will still see the edges of the headset once you look outside of
this boundary. That could one day change, however
This week at the F8 2018 developer conference, Facebook teased a new VR headset prototype with wider lenses that expand the field of view
inside the headset to 140 degrees. Called Half Dome, the headset's lenses would allow users to see a much broader field of view than even
the new, ultra-high end HTC Vive Pro, which still has the traditional 110-degree FOV. What's more, the Half Dome lenses are 'varifocals'
that are controlled mechanically
This means that instead of the focus changing on the software side when you look at something in VR (like what's done with foveated
rendering), the lenses themselves adjust to give you better focus. Varifocals simulate how your real eye adjusts to look at objects, so
putting them in a VR headset would offer a more realistic simulation of visual focus. There's no word on when we'll see the tech inside
Half Dome make it to an actual product, though with signs pointing to a possible Project Santa Cruz release later this year, we could see
this tech sooner rather than later. Via Digital Trends
