Are you lastly prepared to hold a pc display in your face?
Fifteen years in the past, that may have appeared like a foolish query. Then got here the much-hyped and much-derided Google Glass in 2012, and admittedly, it nonetheless appeared a foolish query.
Now, although, it’s a selection shoppers are starting to make. Tiny shows, shrinking processors, superior battery designs, and wireless communications are coming collectively in a brand new technology of smart glasses that show data that’s truly helpful proper in entrance of you. However the huge query stays: Simply why would you need to try this?
Some tech firms are betting that right this moment’s sensible glasses would be the excellent interface for delivering AI-supported data and different notifications. The opposite chance is that sensible glasses will exchange cumbersome pc screens, performing as an alternative as a non-public and moveable monitor. However the firms pursuing these two approaches don’t but know which selection shoppers will make or what purposes they actually need.
Good-glasses skeptics will level to the destiny of Google Glass, which was launched in 2012 and shortly turned a primary instance of a dear expertise in the hunt for sensible purposes. It had little to supply shoppers, except for being an aspirational product that was ostentatiously visible to others. (Some impolite customers had been even derided as “glass-holes.”) Whereas Glass was successful in specialised purposes such as surgery and manufacturing until 2023—no less than for these organizations that might afford to speculate round a thousand {dollars} per pair—it lacked any compelling software for the common client.
Good-glasses expertise might have improved since then, however the units are nonetheless chasing a strong use case. From the tech behemoths to little manufacturers you’ve by no means heard of, the {hardware} as soon as once more is out over its skis, trying to find the correct software.
Throughout a Meta earnings call in January, Mark Zuckerberg declared that 2025 “will probably be a defining yr that determines if we’re on a path towards many a whole lot of tens of millions and ultimately billions” of AI glasses. A part of that willpower comes right down to a selection of priorities: Ought to a head-worn show replicate the pc screens that we at the moment use, or ought to they work extra like a smartwatch, which shows solely restricted quantities of knowledge at a time?
Head-worn shows fall into two broad classes: these supposed for digital actuality (VR) and people suited to augmented actuality (AR). VR’s more-immersive method discovered some early success within the client market, such because the Meta Quest 2 (initially launched because the Oculus Quest 2 in 2020), which reportedly offered greater than 20 million models earlier than it was discontinued. Based on the market analysis agency Counterpoint, nevertheless, the worldwide marketplace for VR units fell by 12 percent year over year in 2024—the third yr of decline in a row—due to {hardware} limitations and a scarcity of compelling use instances. As a mass client product, VR units are most likely previous their second.
In distinction, AR units enable the wearer to remain engaged with their environment as extra data is overlaid within the area of view. In earlier generations of sensible glasses, this data added context to the scene, corresponding to journey instructions or efficiency information for athletes. Now, with advances in generative AI, AR can reply questions and translate speech and textual content in actual time.
Many analysts agree that AI-enhanced sensible glasses are a market on the verge of huge development. Louis Rosenberg, CEO and chief scientist with Unanimous AI, has been concerned in AR expertise from its begin, greater than 30 years in the past. “AI-powered sensible glasses are the primary mainstream XR [extended reality] units which can be profoundly helpful and can obtain speedy adoption,” Rosenberg instructed IEEE Spectrum. “This, in flip, will speed up the adoption of immersive variations to comply with. In reality, I imagine that inside 5 years, immersive AI-powered glasses will exchange the smartphone as the first cell gadget in our digital lives.”
Main tech firms, together with Google and Apple, have introduced their intentions to affix this market, however have but to ship a product. One exception is Meta, which launched the Meta Ray-Ban Display in September, priced at US $799. (Ray-Ban Meta glasses with out a show have been obtainable since 2023.)
Numerous smaller firms, although, have solid the trail for true AR sensible glasses. Two of essentially the most promising fashions—the One Pro from Beijing-based Xreal and the AI glasses from Halliday, based mostly in Singapore—signify the 2 completely different design ideas evolving in right this moment’s smart-glasses market.
Halliday’s “Hidden Superpower”
Halliday’s sensible glasses are a light-weight, inconspicuousdevice that appears like everydayeyewear. The glasses have a single small microLED projector positioned above the correct lens. This imager beams a monochrome inexperienced picture on to your eye, with a degree of sunshine dim sufficient to be protected however vibrant sufficient to be seen in opposition to ambient gentle. What the person sees is a digital 3.5-inch (8.9-centimeter) display within the higher proper nook of their area of view. Like a typical smartwatch display, it may show as much as 10 or so brief strains of textual content and primary graphics, corresponding to arrows when exhibiting turn-by-turn navigation directions, ample to supply an interface for an AI companion.
In press supplies, Halliday describes its glasses as “a hidden superpower to deal with life’s challenges.” And hidden it’s. The display technology is way more discreet than these of different designs that use waveguides or prismatic lenses, which is able to typically reveal a mirrored picture or a noticeable rainbow impact. As a result of it projects the picture on to the attention, the Halliday gadget doesn’t produce any such indications. The glasses may even be fitted with commonplace prescription lenses.
Xreal’s One Professional: The Full Image
In contrast, the Xreal One Professional has two separate imagers—one for every eye—that present full-color, 1,080-pixel photographs that fill 57 levels of the person’s area of view. This permits the One Professional to show the identical content material you’d see on a pocket book or desktop display. (A extra typical area of view for AR glasses is 30 to 45 levels. Halliday’s digital display occupies solely a small portion of the person’s area of view.)

In reality, the One Professional is meant to eradicate these pocket book and desktop screens. “We’re now on the level the place AR glasses’ spatial screens can really exchange bodily screens all day lengthy,” Xreal CEO and cofounder Chi Xu said in a December 2024 press release. Nevertheless it’s not an answer to be used if you’re out and about; the glasses stay tethered to your pc or cell gadget by a cable.
The glasses use microLED imagers that ship good shade and distinction efficiency, together with decrease energy consumption than an OLED. Additionally they use a “flat prism” lens that’s 11 millimeters thick—lower than half the thickness of the prisms in another AR sensible glasses, however three to 4 instances as thick as typical prescription lenses.
The flat-prism expertise is much like the “fowl tub” prisms in Xreal’s earlier glasses, which used a curved floor to mirror the show picture to the wearer’s eye, however the flat prism’s thinner and lighter design provides a bigger area of view. It additionally has benefits over the refraction-based waveguides utilized by different glasses, which might introduce seen artifacts corresponding to coloured halos.
With the intention to enhance the visibility of the projected picture, the glasses block a lot of the ambient gentle from the environment. Karl Guttag, a display-industry skilled and writer of the KGOnTech blog, says that the Xreal One Professional blocks about 78 % of real-world gentle and are “like darkish sun shades.”
The One Professional additionally has a built-in spatial pc coprocessor, which permits the glasses to place a picture relative to a route in your view. For instance, when you have an software that exhibits one set of knowledge to your left, one other within the center, and a 3rd to the correct, you’ll merely flip your head to have a look at a distinct set. Or you may place a picture in a hard and fast location—as with the Halliday glasses—in order that it stays in entrance of you if you flip your head.
Having separate imagers for every eye makes it doable to create stereoscopic 3D results. Meaning you may view a 3D object in a hard and fast location in your room, making for a extra immersive expertise.
The Price of Extra-Immersive AR
All these options come at a price. Xreal’s glasses draw an excessive amount of energy to be run by battery, and so they want a high-speed information connection to entry the show information on a laptop computer or desktop pc. This connection offers energy and permits high-resolution video streaming to the glasses, but it surely retains the person tethered to the host gadget. The Halliday glasses, in contrast, run off a battery that the corporate states can last as long as 12 hours between fees.
One other key distinction is weight. Early AR glasses had been so heavy that they had been uncomfortable to put on for lengthy durations of time. The One Professional is comparatively gentle at 87 grams, or rather less than the load of a small smartphone. However the Halliday’s easier design and direct projector yields a tool that’s lower than half that at 35 grams—a weight much like that of many common prescription glasses.

In each instances, this new technology of consumer-oriented sensible glasses prices a lot lower than enterprise AR techniques, which price a number of hundreds of {dollars}. The One Professional lists for $649, whereas the Halliday lists for $499.
At the moment, neither Halliday nor Xreal has a digital camera constructed into its glasses, which as an alternative talk by means of voice control and audio suggestions. This eliminates further weight and energy consumption, helps hold prices down, and sidesteps the privateness considerations that proved to be one of many primary sticking factors for Google Glass.
There are actually purposes the place a digital camera may be useful, nevertheless, corresponding to for image recognition or when customers with impaired imaginative and prescient need to hear the textual content of indicators learn aloud. Xreal does supply an non-compulsory high-resolution digital camera module that mounts on the bridge of the nostril. Whether or not to incorporate a built-in digital camera in future fashions is yet one more trade-off these firms might want to take into account.
What Do Shoppers Actually Need in Good Glasses?
Clearly, these two fashions of sensible glasses signify very completely different design methods and purposes. The Halliday glasses exist largely as a cell platform for an AI companion that you should use discretely all through the day, the best way you’ll use a smartwatch. The One Professional, then again, can act as a substitute on your pc’s monitor—or a number of screens, because of the spatial computing characteristic. The excessive decision and full shade ship the identical data that you simply’re used to getting from the bigger shows, with the trade-off that you simply’re bodily tethered to your pc.
Are both of those situations the killer app for sensible glasses that we’ve been ready for?
With the rise of generative AI agents, individuals are rising more and more snug with easy accessibility to all kinds of knowledge on a regular basis. Good audio system corresponding to Amazon Echo have educated us to get solutions to absolutely anything just by asking. Sporting a tool in your face that may discreetly current data on demand, like Halliday’s glasses, will definitely attraction to some shoppers, particularly when it’s priced affordably.
Chris Chinnock, founding father of Insight Media, thinks that is the trail for the long run. “I’m not satisfied {that a} show is required for lots of purposes, or when you have a show, a small [field of view] model is ample. I feel audio glasses coupled with AI capabilities could possibly be very fascinating within the close to time period, because the optics [or the] show for extra full-featured AR glasses are developed.”
Then again, many individuals could also be looking for a compact and handy different to the big, cumbersome exterior screens that include right this moment’s laptop computer and desktops. On an airplane, as an example, it’s troublesome to comfortably open your laptop computer display sufficient to see it, and there’s little expectation of privateness on a crowded flight. However with sensible glasses that mission a number of digital screens, you may very well be capable of do some helpful work on a protracted flight.
For now, firms like Halliday and Xreal are hoping that there’s room for each methods within the client market. And with a number of selections now obtainable at consumer-friendly costs, we are going to quickly begin to see how a lot curiosity there’s. Will shoppers select the sensible AI companion, or a compact and personal substitute for pc screens? In both case, your glasses are more likely to turn out to be loads smarter.
