Oculus Research Reveals New Multi-focal Display Tech

Oculus Research, the company’s R&D division, recently published a paper that goes deeper into their eye tracking-assisted, multi-focal display tech, detailing the creation of something they dub a “perceptual” testbed.

Current consumer VR headsets universally present the user with a single, fixed-focus display plane, something that creates what’s known in the field as the vergence-accommodation conflict; the user simply doesn’t have the ability to focus correctly due to the display’s inability to provide realistic focus cues, making for a less realistic and less comfortable viewing experience. You can read more about the vergence-accomodation conflict in our article on Oculus Research’s experimental focal surface display.

Making Bullet Train and Going off the Rails in VR

This 2016 VRDC talk covers the entire process, from start to finish, of making Epic Games’ Bullet Train VR Demo. Epic’s Nick Donaldson and Nick Whiting cover design considerations surrounding the user experience of adding interaction to traditionally passive experiences, and discuss where they had to diverge from their original design choices in order to match the players’ expectations of the world they interact with.

3D SCANNING ENTIRE ROOMS WITH A KINECT

Almost by definition, the coolest technology and bleeding-edge research is locked away in universities. While this is great for post-docs and their grant-writing abilities, it’s not the best system for people who want to use this technology. A few years ago, and many times since then, we’ve seen a bit of research that turned a Kinect into a 3D mapping camera for extremely large areas. This is the future of VR, but a proper distribution has been held up by licenses and a general IP rights rigamarole. Now, the source for this technology, Kintinuous and ElasticFusion, are available on Github, free for everyone to (non-commercially) use.

Single metalens focuses all colors of the rainbow in one point; opens new possibilities in virtual, augmented reality

Single metalens focuses all colors of the rainbow in one point

Metalenses—flat surfaces that use nanostructures to focus light—promise to revolutionize optics by replacing the bulky, curved lenses currently used in optical devices with a simple, flat surface. But, these metalenses have remained limited in the spectrum of light they can focus well. Now a team of researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) has developed the first single lens that can focus the entire visible spectrum of light—including white light—in the same spot and in high resolution. This has only ever been achieved in conventional lenses by stacking multiple lenses.

Pico’s standalone 6DoF VR headset is compatible with Vive Wave

You might have missed the original Pico Neo VR headset back in April 2016, but the name is popping up again thanks to its re-release. Following the HTC Vive Focus, the new Pico Neo unveiled earlier today is yet another standalone VR headset with six-degree-of-freedom (6DoF) tracking, and thankfully, it looks a lot better than its predecessor. Much like the Vive Focus, what we have here is a dual-camera inside-out tracking system powered by Qualcomm’s Snapdragon 835 (so it’s likely based on the same development kit) with the same three-hour battery life, but it features a narrower 101-degree field of view instead of 110, and it packs a pair of 90 Hz 1,440 x 1,600 LCDs instead of AMOLED.
