Facebook’s Reality Labs developed ultra-thin VR specs that use flat-film holographics for optics. The proof-of-concept device, which Facebook says is the thinnest VR display shown yet, has a lens thickness of only 9 mm (0.35 inches) and resembles a pair of sunglasses.
- The displays use polarization-based optical folding - which bends and reflects light back onto itself - to shrink the size.
- Its field of view is more than 90 degrees horizontally, with a per-eye resolution of 1,600 by 1,200 pixels, similar to other VR goggles.
- It currently outputs in monochrome, but Facebook plans to upgrade that to a wider range of colors.
- The company still has to address issues like device connection, eyeglasses compatibility, and battery life, Engadget's Jon Fingas writes.
- Facebook’s research paper was submitted to the SIGGRAPH computer graphics conference, which takes place in August.
