These Lumus displays could fix HoloLens’ big problem

The DK-50, like Lumus’ previous products, use a tiny micro-projector in the arm of the glasses, and a light-guide that runs across each lens. In this particular case, each eyepiece is running at 720p resolution, and since you have a display for each eye you can have 3D graphics, too.

That certainly adds to the realism. Looking around while wearing the DK-50 glasses, I could see a three-dimensional heart floating in mid-air and rotating; that changed to an animated solar system, and then a car engine, also in 3D.

Even in a bright demo hall, the graphics were clear. In a second demo, a 3D dinosaur animation, a virtual jungle was played over the room around me: by shifting focus, I could choose whether to watch the film or engage with people physically present.

Neither of the demonstrations left me confused that the virtual graphics were real, but that could change with the DK-50’s second trick. Atop the frame is a stereoscopic camera array and an Inertial Measurement Unit (IMU), with an onboard Qualcomm Snapdragon processor running Android for markerless augmented reality.

Unlike many AR systems, which require some sort of special glyph or 2D barcode in order to orient the virtual graphics on top of the real world, the InfinityAR system Lumus is using do the same but by identifying elements of the surrounding environment.

Unfortunately, Lumus’ prototypes weren’t up and running with the AR system so I wasn’t able to test that out.

While the DK-50 will be sold as a development kit for would-be AR wearable manufacturers, it’s the Lumus displays that have plenty of potential for addressing common complaints in products like HoloLens.

That’s because of the field of view (FOV), or in other words the amount of your vision that the digital display covers. In the case of the displays in the DK-50, that’s 40 degrees: enough to occupy roughly the same sort of area as watching a big-screen TV from across the average room.

Importantly, though, it extends higher and lower in the field of vision than HoloLens’ 20 degree FOV displays did, something particularly noticeable – and intrusive into the AR experience – when digital objects suddenly clipped or disappeared as you turned or nodded your head slightly.

Lumus’ “optical engines” still aren’t enough to give you a fully digital view, but it’s significantly better than what I’ve seen from other head-up displays. The company says it’s working on 60-degree FOV versions that could arrive as early as this year, while 1080p displays are also on the roadmap.

In a second demonstration, another brand-new prototype – the DK-45, one of only three currently in existence, in fact – showed how Lumus is hoping to help slim the form-factor down until AR glasses can look like regular spectacles. The DK-50 isn’t going to be mistaken for that, and – to be fair – neither is this new, monocular model, but it’s definitely sleeker even than the DK-40 reference design I played with back in 2014.

Clearly you’re not going to get 3D, but you do get a sizable Android interface floating in your right eye. Right now there’s nothing much you can actually do with it – Lumus didn’t have any eyewear-specific apps loaded – but it was a huge improvement on workable display size compared to, say, Google’s Glass (which has a mere 15 degree FOV).

That’ll be targeted at enterprise users, somewhere AR has still had more success than among the general public, but as the quality of the displays – and the user experiences developers offer – improve, we could see a significant shift in that beginning this year.

Lumus’ New Smart Glasses Displays Are Ar For Everyone

Lumus’ new smart glasses displays are AR for everyone

Smart glasses are coming, and since augmented reality wearables need to be closer to designer sunglasses than they are to Google Glass, transparent displays need to raise their game. That’s just what smart eyewear display specialist Lumus is doing, bringing along its latest Sleek display prototype to CES 2023 this week to show how AR could have mass-market appeal.

The goal, unsurprisingly, is to put transparent displays into eyewear that wouldn’t look out of place racked next to traditional eyeglasses and sunglasses. For that Lumus’ latest consumer focused side-mounted optical engine has a much smaller footprint, and is less bulky too.

“One of the major improvements we’ve made, we’ve done a lot more about 2-axis expansion,” Ari Grobman, CEO of Lumus, explained to SlashGear exclusively ahead of the show. “It’s basically how the waveguide expands the image on one axis, but also while you expand the projection into the waveguide.”

The result is a smaller projection unit, but without necessarily compromising on what the wearer sees. This new Lumus Sleek design still delivers 720p resolution graphics in each eye, and with a 40-degree field-of-view. Grobman suggests even bigger improvements are just at hand, promising “a quantum leap in field-of-view” and form-factor in the second half of the year or toward the end of 2023. That could mean 50-degree FoV but with an even smaller projection.

Still, while the tech projections might show full vision, binocular AR as the way the future is mapped out, Grobman says that a more focused version is also unexpectedly gaining traction again. A demand for binocular displays has picked up over the past year.

“Single eye is actually making a comeback now,” Grobman explained. “As the manufacturer of the optical engine, we see varying approaches to the market. Some want something really slimmed down – even as small as a monocular engine, potentially with an even smaller field-of-view – there is that side of the market that wants the minimally viable product, say “AR Lite.” What Google Glass should’ve been.”

The biggest question, of course, is just when we’ll actually see true augmented reality glasses on the market – and under which brand. Lumus doesn’t make the eyewear, only the displays for it, and the company won’t be drawn on which companies it supplies. Still, Grobman would say that a pilot production line with partner Quanta is already running, and that the main line will begin operating in the next several months. Even that pilot line, though, has given the company something to demonstrate.

When, therefore, might we be able to buy a set ourselves? Again, Lumus doesn’t control that roadmap, and indeed the company argues that it’s not the pinch-point for the wearable form-factor.

“2023 is still possible with some of the companies we’re talking to, doing much more modest soft launches,” Grobman says. “But when we’re thinking of Tier 1, real consumer brands and real adoption, the timelines we’re working with… really, we’re not the bottleneck here at all. Really, it’s the process of getting the rest of the product in line, the software and the interface, that’s the bottleneck.”

“Theoretically, I could say the holiday season of 2023,” he suggested, for a mass-market launch with 1m+ sales expectations. “But that could easily slip through to early or mid-2023.”

Whenever it happens, you should probably set aside the same sort of lump sum as you’d spend on a smartphone today. Current AR products, like Microsoft HoloLens and Magic Leap, command price tags in the several thousands, admittedly for what are developer-focused devices. Consumer versions should – and will need to be – more attainable.

“I think everyone’s goal was to keep it at smartphone pricing,” Grobman suggests. “A full, all-in-one system – whether it’s going to be a peripheral to a smartphone, or whether it’s going to be embedded – it’s going to be akin to the price of a smartphone.” In an age of $1k+ iPhones, of course, that isn’t quite the promise of tech affordability it once was.

Which of the contenders will use Lumus’ technology remains to be seen. The company has no shortage of boasts – “we are the industry benchmark” for image brightness, resolution, clarity, color uniformity, and field-of-view, Grobman insists – though it’s not the only player in the game. Meanwhile AR demands new content and experiences in order to sell itself: having display technology that makes for almost unremarkable eyeglass designs is only one small part of the battle.

These Footprints Could Push Back Human History In The Americas

A set of footprints buried in the dunes of New Mexico’s White Sands National Park has landed in the middle of an ongoing reevaluation of the human history of the Americas.

The prints were left over thousands of years by humans who walked among giant sloths, camels, and mammoths on the grassy shores of a lake 23,000 years ago, as determined by radiocarbon dating of grass seeds found around the footprints.

That’s in stark contrast to the conventional hypothesis in archaeology, which holds that the first Americans crossed over between 16,000 and 12,000 years ago, when the glaciers still covered North America, and Siberia and interior Alaska were part of the same grassy subcontinent called Beringia.

But the footprints aren’t the first find to contradict that hypothesis. In 2023, a team found what they believe to be 30,000-year-old stone tools in a cave in central Mexico, followed shortly by another find in Mexico that may be more than 20,000 years old. They haven’t reshaped consensus within the field, because of questions over either the artifacts themselves or the dating used on the site.

Yet even archaeologists who aren’t convinced of older habitation agree that these footprints could cause them to rethink their views. “White Sands is clearly different as there are no artifacts to debate,” says Jesse Tune, an archaeologist at Fort Lewis College. “It’s hard to imagine more conclusive evidence for human activity than the literal [footprint] of someone standing on the shoreline of a lake ~23,000 years ago.”

It’s hard to find an archaeological site that isn’t up for some interpretation. “If folks are walking on that lake bed for 2,000 years, there should also be a bunch of archaeological sites associated with them that are nearby,” says Jessi Halligan, an archaeologist who studies the early habitation of the Americas at Florida State University. “Hopefully a few were preserved and are dateable to tell us more. Having some kids and teenagers trekking around in the mud is exciting, but as archaeologists, we always want to know more of the story.”

If the footprints do tip the scales towards an older migration, that could lead to a wider reevaluation of other pre-glacial artifacts. And that wouldn’t be the first time in recent decades that the archaeological consensus around the settling of the Americas has changed. Until the 2000s, there was still open debate over whether a group known as the Clovis people were the first inhabitants of the Americas. More recent genetic and archaeological evidence, however, has made it clear that other peoples had arrived earlier.

“There are many sites that have really good dating and really good reports that are much older,” says Paulette Steeves, an archaeologist at Algoma University who studies Indigenous history, and author of The Indigenous Paleolithic of the Western Hemisphere. She’s compiled hundreds of finds that she finds credible that date back before 16,000 years.

Other archaeologists argue that these older sites contain less clear-cut evidence than the newer ones, making them less compelling against a widely held theory.

Once a hypothesis is established, it takes an extra lift to overturn it. “Archaeology is a careful balance of skepticism and open-mindedness, and I’m cautious to get too excited about the White Sands prints until we have more information,” says Tune.

Tune’s previous research on other possible pre-glacial sites, which might overturn the conventional hypothesis, has turned up blank: in 2023, he investigated three older sites and found that in each case, what had appeared to be stone or bone tools were either formed naturally, or couldn’t be definitively connected to the ancient layers.

But Steeves approaches the existing ancient sites differently. There’s a long history of what she describes as “violent criticism against archaeologists discussing older sites.” Steeves is Cree-Metis, and says that tendency is rooted in archaeology’s use as a tool to discount Indigenous claims to North America.

To her, the existing finds tell a consistent story of human habitation in the Americas that goes back hundreds of thousands of years. “There’s a word in the Cree language that means ‘when the glaciers went home,’ or ‘when the ice went home,’” she says. “People have those words in their Indigenous language because they were here before, right?”

She argues those non-physical pieces of evidence are important for contextualizing older archaeological sites. “Good science looks at every form of evidence available to highlight what you’re looking to discuss.”

“I always like to remind people to think critically,” says Steeves. “[Human] history has changed so much over the last 100 years, everywhere in the world. We’re always doing more excavations, we’re always finding out more.”

Crypto Market Cap Could Fall Below Us$1 Trillion If These Things Don’t Change

The crypto bulls have to work a lot harder to experience a surge in their value

Bitcoin’s value fell by more than half of its value since its all-time highs in November 2023, leading to a major crash in the entire cryptocurrency market. Meanwhile, as soon as investors had started to recover from Bitcoin’s fall, Terra and TerraUSD massively wounded the rest of the market by declining further below. The fall of the Terra ecosystem spilled a wave of fear and chaos leading to an early self-off season. This weak sentiment had spread across the crypto market resulting in investors withdrawing their money and dumping their investments. According to market experts, Bitcoin and Ethereum, the two most valuable assets in the market have decreased by more than 40% since mid-November of 2023. In recent times, the price of Bitcoin has fluctuated more than any investor could have ever imagined. As the crypto is set around the US$29,000 mark, investors feel relieved thinking that the crypto has finally stabilized, but experts predict that Bitcoin is due for more fluctuations. Recently, reports have revealed that the total crypto market cap is down by almost 43% within a period of just two months. But the market will soon regain its glory if certain metrics are set straight.

The crypto market cap has been ranging from US$1.19 trillion to US$1.36 trillion for a period of 20 to 23 days. At this point, Bitcoin witnessed a gain of 3.5%, whereas, Ethereum experienced a gain of about US$1.6%, which somewhat relieved the investors. But the cryptos fell back again! Besides this, the fears of regulation continue to weigh over investors’ crypto-buying preferences. BTC’s decline since November’s high has approximately blotted out about US$600 billion in market value and over US$1 trillion from the broader crypto market. Turmoil in stablecoins has introduced the added misery of greater liquidity in cryptocurrencies.

The Important Metrics to Consider in this Bear Market

No investor would like to face a bearish crypto market as they destroy portfolio value and possess a high tendency to cause financial losses to its investors. But one of the most profitable aspects of a bearish crypto market is that it provides investors with the time to reconsider their investments and research more on other profitable projects that might thrive when the prices surge again.

The Fear and Greed Index is a data-driven sentiment gauge that clearly depicts the bearish sentiment of the crypto market. The indicator has consistently maintained its position below 20 since May 8, as the crypto market touched its lowest levels when it lost US$1.7 trillion. According to reports, Cardano continues to gain 19% as the Vasil hard fork is waiting for its launch quite soon. The upgrade aims to improve scalability and ADA’s smart contract functionality by galvanizing deposits over the decentralized network.

Major altcoins like Solana fell more than experts could have ever been anticipated. SOL has been constantly facing network issues for a period of seven months.

Besides these issues, the situation around Tether has also been quite challenging for the crypto market and its investors. The re-launch of the LUNA 2.0 protocol has not been helping because LUNA users as still speculative and skeptical about its future. Most of the long-term crypto buyers have left the crypto market or are also choosing other centralized, traditional assets to avoid further financial accidents.

Bottom Line

There are several price metrics that need to change for the crypto market to rise again. Experts believe that the research they conveyed posed evidence of more downsides. This is mainly because of the slightly higher conditions of altcoins on the bearish levels and also due to the evident lack or loss of interest in investing in cryptocurrencies from the Asian retail markets. It is evident that crypto bulls have to show much more capability to attract more investors in the market.

A number of people have reported seeing the Xbox One error 0x87dd001e after the console lost its axes to wireless. If you’re also experiencing this issue, you’re no doubt very frustrated. But don’t worry, it can be fixed.

Before moving forward and trying repair solutions that work in situations where the problem occurs locally, make sure you aren’t facing a temporary issue with the Xbox server. Once this option is ruled out, network status glitches and corrupted temporary folders step in as potential culprits.

Therefore, waste no more time and use the following solutions to resolve this problem.

What can I do when getting Xbox One error 0x87dd001e? 1. Perform a full power cycle of your console

Firstly, you should power cycle your console. This procedure will successfully help you to eliminate the majority of temporary files that might cause this sort of issue, so you know what you have to do.

Immediately hold the Power button on the console for 10 seconds or until the power shuts down completely. Unplug the power cord from the back of the console. Plug the power cord back in after waiting around 5 minutes to ensure that the procedure is successful, then restart the console.

Do so by pressing the Xbox button on your console to turn it on and you should now see the green boot-up animation.

2. Reset the alternate MAC address

Press the Xbox button to bring up the guide overlay.

Choose All Settings from the context menu.

Once you manage to get inside the Settings menu, go to Network settings.

From the Network menu, move to the Advanced Settings menu on the left-hand side.

With the Advanced settings menu selected, choose the Alternate MAC address from the list of available options.

Don’t hesitate to hit the Clear button.

Up next, hit the Restart button to apply the changes.

At the next startup sequence, log-in with your account once again and see if the error persists.

So, if you still get the Xbox One error 0x87dd001e, then we strongly recommend that you clear the alternate MAC address from the Xbox One settings menu. This solution is effective if the ISP that’s being used is providing a dynamic IP.

You can’t open Xbox One guide? Take a look at this step-by-step procedure to find a solution.

3. Factory reset your Xbox One

Press the home button on your Xbox One controller.

Navigate to the System Menu and select Settings.

Select Reset console next.

At this point, you have the option to either Reset and remove everything or Reset and keep my games & apps (you may also cancel and back out if you’re undecided).

Select the Reset and keep my games & apps section.

Hit the X button to start the procedure.

Once you’ve selected that, the console will proceed with erasing content, which could take several minutes.

Your console will eventually restart automatically.

We have also managed to identify several user reports in which a factory reset resolved the issue entirely. The best part is that Microsoft makes this very easy to do, whether you want to keep your games and apps installed, or give your console a fresh start.

Anyway, if you choose to keep them installed, note that the procedure will still remove all personal files and associations from the console. All your saved games, achievements, settings, and accounts are though synced up with Xbox Live.

Still experiencing troubles? Fix them with this tool:


Some driver-related issues can be solved faster by using a tailored driver solution. If you’re still having problems with your drivers, simply install OutByte Driver Updater and get it up and running immediately. Thus, let it update all drivers and fix other PC issues in no time!
