Lumus demonstrates futuristic 3,000-nit AR glasses at CES 2023

Lumus recently announced its next-gen waveguide technology for AR glasses that will have a wider field of view and a brighter display, while being much more efficient than other solutions. We spoke with the Vice President of Marketing David Andrew Goldman about Lumus’ new Z-Lens design and technology to get the full scoop.

Building upon the already impressive, reflective waveguides used in the 2D Maximus design, the second generation Z-Lens can deliver a 3,000-nit display at 2K-by-2K resolution in an optical engine that’s 50% smaller, resulting in a pair of AR glasses that could weigh as little as 50 grams (in a monocular design). This makes it possible to manufacture stylish, lightweight AR glasses without any tradeoffs, such as tinting the lens or frequent charging.

The challenge with AR glasses is getting enough light to the display efficiently to allow a useful runtime while maintaining an attractive and unobtrusive appearance. Lumus waveguide technology has been estimated by AR display expert Karl Guttag to be five to ten times more efficient than competing solutions.

Goldman feels that the problem has been solved with the Lumus Z-Lens and shared that the company is working with multiple tier-one tech companies on future AR glasses. It will be two to three years before these products are likely to launch, but it’s exciting to learn more about what to expect in the future as this technology matures.

The final design of AR glasses is determined by the product manufacturer, but Goldman shared some details of what might reasonably be expected in terms of product specifications and pricing. With a cost roughly equivalent to a high-end smartphone, future AR glasses won’t be inexpensive, but should be priced within reach of most consumers.

At that $1,000 plus price, you can expect a comfortable, lightweight pair of glasses built with Lumus Z-Lens waveguide technology to look quite similar to normal eyewear. The display will have a 50- to 80-degree field of view and battery life will be sufficient for several hours of use. The bright, sharp display will be easily readable even when used outdoors.

A smartphone will probably still be needed for some features, like calling and GPS location tracking, but much of the processing will occur within the AR glasses. As Lumus likes to say “the future is looking up,” and the need to glance down at your smartphone will be greatly reduced in the near future as AR advances and becomes more commonplace.

AMD CES 2023: Ryzen 9 7950X3D, mobile Ryzen 7000, and more
AMD CEO Lisa Su delivering AMD's CES 2023 keynote.

AMD's CES 2023 keynote is over, officially kicking off the show (although, most of the major announcements are already out of the way). Team Red had a lot to share, including Ryzen 7000X3D parts, Ryzen 7000 mobile CPUs, and new RX 7000 mobile GPUs. To catch you up, here's everything AMD announced at CES 2023.
XDNA and Ryzen 7000 mobile

AMD started off its presentation with a bit about its XDNA architecture, and critically, how it powers a new Ryzen AI engine in Ryzen 7000 mobile CPUs. AMD has a full stack available, but it highlighted the 7040 and 7045 series during its keynote. The 7040 series goes up to eight cores and 28 watts, and it's built using the same Zen 4 architecture as desktop Ryzen 7000 CPUs. In fact, it uses the same chiplet design as desktop CPUs, just in different packaging.

CES 2023: These 38-gram smart glasses aim to make AR practical
Vuzix AR wearables are remarkably thin, like regular glasses.

We spoke with Vuzix founder and CEO Paul Travers about the recently announced Vuzix Ultralite smart glasses manufacturer reference design. The Vuzix hardware will be the basis for some of the most practical, tech-enhanced eyewear arriving in 2023.

Smart glasses built on the Vuzix Ultralite design can provide hands-free access to notifications, directions, fitness tracking, and more. The need to continually haul a smartphone out of your pocket, interrupting conversations to check messages, might soon come to an end. That information will be unobtrusive, yet visible in a sharp, bright display that features microLED and waveguide technology.
