As you can see from the top image, it is sunglasses by all means.Strong sunglasses.… No, it's kind of something, and it's even a camera filter.But this is the next -generation VR headset that Facebook is under development.
Facebook talks about the VR headset under R & D in the report of the SIGGRAPH 2020 "HOLOGRAPHIC Optics for Thin and Lightweight Virtual Reality".The latest prototype is adopted a VR display called "Pancake Optical", which makes multiple holographic films.It is a display of 9 to 11 mm, which is slightly thicker than a smartphone.
The prototype is the same level as Oculus Quest, 1200 x 1600 pixels (16 inches x 21).3 inches), visibility is 93 degrees for circles and 69 degrees for rectangles.Uses a laser projection system and a display backlight.The weight is only 10 grams.Oculus Quest is 571 grams, so it is considerably lighter, not just for glasan.
According to Facebook Research blogs, many VR displays use a refractive lens made by scraping glass and plastic, so that the eyes and lenses need to be kept at a certain distance in order to properly capture the image.The headset will be a box -shaped big design.Therefore, FB is studying a thin headset using holographic optics.Rather than passing light directly to the lens, if it is a holographic lens to make the light back to the display before the light refracts, the terminal should be able to slim.On the blog, the concept video is also explained, but the only image you can do so far is only green monolora.Currently, a full -color prototype is also undergoing research.
Facebook is just a "research" and is not a stage to promise something in the future, but I want to expect it.As long as it is a box -shaped and heavy headset, I don't think VR will be a big hit with the general public.Even if it is limited to game terminals, it is not difficult to wear it for a long time, and it is not easy to move.After all, we go to the world of VR.
… Looking at the VR screen with this sunglasses, it seems that Ichhatel feeling is stronger.
