Are you lastly prepared to hold a pc display screen in your face?
Fifteen years in the past, that might have appeared like a foolish query. Then got here the much-hyped and much-derided Google Glass in 2012, and albeit, it nonetheless appeared a foolish query.
Now, although, it’s a alternative customers 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 info that’s really helpful proper in entrance of you. However the large query stays: Simply why would you need to do this?
Some tech firms are betting that right now’s good glasses would be the excellent interface for delivering AI-supported info and different notifications. The opposite risk is that good glasses will change cumbersome pc screens, appearing as an alternative as a personal and transportable monitor. However the firms pursuing these two approaches don’t but know which alternative customers will make or what purposes they actually need.
Sensible-glasses skeptics will level to the destiny of Google Glass, which was launched in 2012 and rapidly grew to become a chief instance of an expensive expertise searching for sensible purposes. It had little to supply customers, except for being an aspirational product that was ostentatiously visible to others. (Some impolite customers have been even derided as “glass-holes.”) Whereas Glass was a hit in specialised purposes such as surgery and manufacturing until 2023—at the least for these organizations that might afford to take a position round a thousand {dollars} per pair—it lacked any compelling utility for the common shopper.
Sensible-glasses expertise might have improved since then, however the gadgets 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 utility.
Throughout a Meta earnings call in January, Mark Zuckerberg declared that 2025 “might be a defining 12 months that determines if we’re on a path towards many a whole bunch of hundreds of thousands and finally billions” of AI glasses. A part of that willpower comes all the way down to a alternative of priorities: Ought to a head-worn show replicate the pc screens that we presently use, or ought to they work extra like a smartwatch, which shows solely restricted quantities of data at a time?
Head-worn shows fall into two broad classes: these supposed for digital actuality (VR) and people fitted to augmented actuality (AR). VR’s more-immersive strategy discovered some early success within the shopper 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. In line with the market analysis agency Counterpoint, nevertheless, the worldwide marketplace for VR gadgets fell by 12 percent year over year in 2024—the third 12 months of decline in a row—due to {hardware} limitations and a scarcity of compelling use circumstances. As a mass shopper product, VR gadgets are in all probability previous their second.
In distinction, AR gadgets enable the wearer to remain engaged with their environment as extra info is overlaid within the area of view. In earlier generations of good glasses, this info added context to the scene, equivalent to journey instructions or efficiency knowledge 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 good glasses are a market on the verge of huge progress. 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 good glasses are the primary mainstream XR [extended reality] gadgets which can be profoundly helpful and can obtain speedy adoption,” Rosenberg advised IEEE Spectrum. “This, in flip, will speed up the adoption of immersive variations to observe. Actually, I consider that inside 5 years, immersive AI-powered glasses will change the smartphone as the first cell machine in our digital lives.”
Main tech firms, together with Google and Apple, have introduced their intentions to hitch 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 no show have been accessible since 2023.)
Numerous smaller firms, although, have solid the trail for true AR good glasses. Two of probably the most promising fashions—the One Pro from Beijing-based Xreal and the AI glasses from Halliday, primarily based in Singapore—symbolize the 2 totally different design ideas evolving in right now’s smart-glasses market.
Halliday’s “Hidden Superpower”
Halliday’s good 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 secure however brilliant sufficient to be seen in opposition to ambient mild. What the person sees is a digital 3.5-inch (8.9-centimeter) display screen within the higher proper nook of their area of view. Like a typical smartwatch display screen, it might probably show as much as 10 or so quick strains of textual content and fundamental graphics, equivalent to arrows when exhibiting turn-by-turn navigation directions, enough to supply an interface for an AI companion.
In press supplies, Halliday describes its glasses as “a hidden superpower to sort out 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 can typically reveal a mirrored picture or a noticeable rainbow impact. As a result of it projects the picture on to the attention, the Halliday machine doesn’t produce any such indications. The glasses may even be fitted with customary 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 pictures 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 screen. (A extra typical area of view for AR glasses is 30 to 45 levels. Halliday’s digital display screen occupies solely a small portion of the person’s area of view.)

Actually, the One Professional is meant to get rid of these pocket book and desktop screens. “We’re now on the level the place AR glasses’ spatial screens can actually change 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 whenever you’re out and about; the glasses stay tethered to your pc or cell machine by a cable.
The glasses use microLED imagers that ship good colour 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 good glasses, however three to 4 occasions as thick as typical prescription lenses.
The flat-prism expertise is just like the “chook tub” prisms in Xreal’s earlier glasses, which used a curved floor to replicate the show picture to the wearer’s eye, however the flat prism’s thinner and lighter design gives a bigger area of view. It additionally has benefits over the refraction-based waveguides utilized by different glasses, which may introduce seen artifacts equivalent to coloured halos.
In an effort to enhance the visibility of the projected picture, the glasses block a lot of the ambient mild from the environment. Karl Guttag, a display-industry skilled and writer of the KGOnTech blog, says that the Xreal One Professional blocks about 78 p.c of real-world mild and are “like darkish sun shades.”
The One Professional additionally has a built-in spatial pc coprocessor, which allows the glasses to place a picture relative to a route in your view. For instance, you probably have an utility that reveals one set of data to your left, one other within the center, and a 3rd to the correct, you’ll merely flip your head to take a look at a unique set. Or you may place a picture in a set location—as with the Halliday glasses—in order that it stays in entrance of you whenever 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 set location in your room, making for a extra immersive expertise.
The Value 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, they usually want a high-speed knowledge connection to entry the show knowledge on a laptop computer or desktop pc. This connection gives energy and allows high-resolution video streaming to the glasses, however it retains the person tethered to the host machine. The Halliday glasses, against this, run off a battery that the corporate states can last as long as 12 hours between expenses.
One other key distinction is weight. Early AR glasses have been so heavy that they have been uncomfortable to put on for lengthy durations of time. The One Professional is comparatively mild at 87 grams, or rather less than the burden of a small smartphone. However the Halliday’s less complicated design and direct projector yields a tool that’s lower than half that at 35 grams—a weight just like that of many common prescription glasses.

In each circumstances, this new technology of consumer-oriented good glasses prices a lot lower than enterprise AR techniques, which value 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 digicam constructed into its glasses, which as an alternative talk via 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 principal sticking factors for Google Glass.
There are definitely purposes the place a digicam will be useful, nevertheless, equivalent to for image recognition or when customers with impaired imaginative and prescient need to hear the textual content of indicators learn aloud. Xreal does provide an non-compulsory high-resolution digicam module that mounts on the bridge of the nostril. Whether or not to incorporate a built-in digicam in future fashions is yet one more trade-off these firms might want to take into account.
What Do Shoppers Actually Need in Sensible Glasses?
Clearly, these two fashions of good glasses symbolize very totally 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 way in which you’ll use a smartwatch. The One Professional, alternatively, can act as a substitute on your pc’s monitor—or a number of screens, due to the spatial computing characteristic. The excessive decision and full colour ship the identical info 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 eventualities the killer app for good 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 types of data on a regular basis. Sensible audio system equivalent to Amazon Echo have educated us to get solutions to absolutely anything just by asking. Carrying a tool in your face that may discreetly current info on demand, like Halliday’s glasses, will definitely attraction to some customers, particularly when it’s priced affordably.
Chris Chinnock, founding father of Insight Media, thinks that is the trail for the longer term. “I’m not satisfied {that a} show is required for lots of purposes, or you probably have a show, a small [field of view] model is enough. I believe audio glasses coupled with AI capabilities may very well be very attention-grabbing 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 various to the massive, cumbersome exterior screens that include right now’s laptop computer and desktops. On an airplane, as an illustration, it’s tough to comfortably open your laptop computer display screen sufficient to see it, and there’s little expectation of privateness on a crowded flight. However with good glasses that venture 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 shopper market. And with a number of decisions now accessible at consumer-friendly costs, we are going to quickly begin to see how a lot curiosity there may be. Will customers select the good AI companion, or a compact and personal substitute for pc screens? In both case, your glasses are more likely to change into quite a bit smarter.
