Researchers at Stanford College and Nvidia have teamed as much as assist develop VR glasses that appear to be common glasses. OK, they are going to look foolish due to the ribbon extending out from both eye, however they’re much more flattering and compact than your typical goggle-like digital actuality headset immediately.
“A serious obstacle to the widespread adoption of VR expertise is the huge kind issue and related difficulties of current VR shows,” stated the analysis paper revealed in Siggraph 2022. (opens in new tab) it’s stated.
The aptly named “holographic glasses” can present a full-color 3D holographic picture utilizing optics which are solely 2.5 mm thick. In comparison with the standard method VR headsets work, by which a lens enlarges a small show at a distance, shrinking all the mandatory elements to such a small measurement is a superb step ahead for VR.
The holographic glasses prototype makes use of pancake lenses, an idea that has been tossed round a few instances through the years. Not solely do these pancake lenses permit for a a lot smaller profile however they reportedly have another advantages too: The decision they’ll supply is alleged to be limitless, that means you possibly can crank up the decision for a VR headset. they usually supply a really broad area of view of as much as 200 levels.
Earlier prototypes for Pancake VR glasses earlier than have managed to make use of them to cut back the hole between the lens and the display to a small fraction of immediately’s VR headsets. Nevertheless, they may solely show 2D pictures. Not nice for immediately’s immersive experiences.
The Stanford and Nvidia units hope to construct on these earlier prototypes: each delivering 3D pictures and decreasing the hole between the lens and display even additional.
The analysis paper lists the glasses as: “A coherent mild supply added to a pupil-replicating waveguide that gives illumination for a phase-only SLM is mounted on the waveguide in entrance of the consumer’s eyes. This SLM creates a tiny picture on the again of the machine, which is magnified by a skinny geometric part (GP) lens.”
Simply your regular stuff, then.

Granted, it is a complicated matter that you just may simply flip your head round from the paper alone, and I’ve little question that the outcomes are personally extra spectacular. Nevertheless, the tip result’s a really small VR machine that could possibly be game-changing when made a actuality exterior the lab. It additionally weighs solely 60 grams, which is far lighter than Meta Quest 2 (opens in new tab)Which rolls in at 503g.
Nevertheless, it guarantees to be extra than simply an instantly shippable product immediately. There are a number of limitations: Whereas there’s room for a a lot larger FOV than with current-generation VR headsets, this explicit wearable prototype solely provided an FOV of twenty-two.8 levels. The benchtop prototype provided even much less, at solely 16.1°.
,[The FOV] A lot smaller than commercially out there VR/AR shows. Nevertheless, the FOV was restricted primarily by the scale of the SLM out there and the focal size of the GP lens, each of which might have been improved with completely different parts,” say the researchers.
One other limitation is the potential want for very exact measurement of the consumer’s pupil, which might not be simple with no nicely thought out design. It might be potential to make use of an infrared gauge tracker to do that, the researchers word, however you would wish to have the ability to constantly observe the scale of the wearer’s pupil as a result of they might usually modify to completely different lighting circumstances when utilizing the glasses.
You’ll be able to learn in regards to the full venture in a lately revealed analysis paper titled “Holographic Glasses for Digital Actuality (opens in new tab)by Jonghyun Kim, Manu Gopakumar, Suyon Choi, Yifan Peng, Ward Lopes and Gordon Weitzstein.
However there’s additionally one thing very spectacular about these idea VR glasses. Because the researchers put it: “With the thought of contemplating HDO and pupil measurement to the consumer’s pupil as a pure Fourier filter in addition to the Scholar-HOGD algorithm, a real glasses-form issue holographic VR is offered for the primary time. was.”
Now simply have to attend and see which enterprising firm places it to good use in transport product.
