Xreal Prevails in Patent Dispute with Viture, Resulting in Prohibition of Sales in Germany

A recent judicial conflict has led to Viture’s augmented reality (AR) glasses being taken down from Amazon in nine countries within the European Union. The dispute revolves around a patent contention with Xreal, a rival in the AR sector. A German court determined that Viture’s AR equipment violated Xreal’s optics patent, resulting in a sales halt in Germany and impacting Viture’s EU distributor, Eden Future. This legal order has prohibited the sales, imports, and promotion of Viture’s offerings, which include the Viture Pro, Luma, and Luma Pro, throughout Germany, France, Italy, Spain, Poland, the Netherlands, Ireland, Sweden, and Belgium.

The Munich 1st Regional Court granted a preliminary injunction connected to European Patent EP3754409B1, which is owned by Xreal and pertains to an augmented reality device and its optical system. The court concluded that Viture’s optical display stack was nearly identical to Xreal’s patented solution, resulting in the prohibition of sales. This case sets a pivotal legal precedent within the XR sector, emphasizing the significance of patent ownership and safeguarding in the competitive AR landscape.

Xreal possesses over 800 patents globally, with a substantial number in both Europe and the US, while Viture has less than 60 patents worldwide. Viture has voiced strong opposition to the decision, claiming that the contested patent is recently granted and should be rendered invalid by a preceding patent. The firm asserts that the injunction is provisional and maintains that its products are still available throughout Europe. Viture has also commenced legal proceedings in China against Xreal for what it labels as misleading rumors.

The result of this legal struggle highlights the essential role of intellectual property in the technology sector and the possible repercussions of patent disagreements on market dynamics and product accessibility.

The Wallet Finder employs Bluetooth technology instead of GPS. It sends out a low-energy Bluetooth signal that can be detected by nearby Apple devices. This signal is then transmitted to the Find My network, allowing users to find their wallet even from a distance, as long as there are Apple devices in the vicinity. The system incurs no ongoing subscription costs, making it a budget-friendly choice.

The efficiency of the Find My network is apparent, as location updates happen swiftly when the wallet is stationary and in proximity to other iOS devices. In cases where the wallet is in motion, updates might trail slightly behind the real-time situation.

Users have the option to mark their wallet as lost, enabling those who come across it to obtain the owner’s contact details via the Identify Found Item feature in Find My. The forthcoming iOS 18.2 update is set to further enhance this capability.

#### Locating Nearby with the Speaker
Although the Wallet Finder does not include the ultra-wideband technology present in the AirTag, it makes up for this by having a built-in speaker that emits a loud sound when activated. This is particularly beneficial for finding a misplaced wallet at home. Users can effortlessly trigger the sound using the Find My app or through Siri, ensuring quick retrieval of the wallet.

#### Safety and Tracking
The SwitchBot Wallet Finder is primarily intended for recovering lost items rather than tracking people. If the card becomes detached from its owner, it produces a noise to alert nearby individuals and sends notifications to nearby iPhones. However, it is crucial to acknowledge that someone else can turn off the Find My connection by executing a specific shutdown procedure.

#### Summary
The SwitchBot Wallet Finder represents a practical and economical solution for those wanting to keep tabs on their wallets. Its compact design enables easy placement within a wallet, and it even features a hole for lanyard or keychain attachment if preferred.

A potential drawback is that the Wallet Finder is a single-use device with an approximate battery lifespan of three years, after which it cannot be replaced. Nevertheless, considering the worth of the items generally held in a wallet, acquiring a new Wallet Finder when the battery expires may be a sensible choice for numerous users.

Apple Research Uncovers Possibilities of AI-Enhanced ISP to Improve Low-Light Photography on iPhones

# Apple’s DarkDiff: Transforming Low-Light Photography with AI

Apple’s researchers have made remarkable progress in improving extremely dark images through the creation of an AI model named DarkDiff. This groundbreaking technique incorporates a diffusion-based image model directly within the camera’s image processing pipeline, allowing for the retrieval of details from raw sensor data that usually gets lost in low-light scenarios.

## The Challenge of Extreme Low-Light Photos

Taking photos in very dark settings often results in grainy images filled with digital noise. This happens when the image sensor does not capture enough light, leading to a loss of detail. To mitigate this, companies like Apple have turned to image processing algorithms. However, these algorithms have been criticized for producing overly smooth images that lack intricate detail, resulting in a painted effect where the original content becomes unrecognizable.

## Introducing DarkDiff

To tackle the difficulties of low-light photography, researchers from Apple and Purdue University unveiled DarkDiff, as outlined in their study titled “DarkDiff: Advancing Low-Light Raw Enhancement by Retasking Diffusion Models for Camera ISP.” The researchers emphasize that achieving high-quality photography in extreme low-light conditions remains a challenge, but improvements in computing hardware are facilitating smarter enhancement of noisy raw images.

DarkDiff differs from conventional post-processing techniques by repurposing Stable Diffusion, an open-source model trained on millions of images. This model is engineered to comprehend which details should appear in dark areas of photos based on their overall context and is integrated into the image signal processing (ISP) pipeline of the camera.

The DarkDiff framework calculates attention over localized image patches, which helps in maintaining local structures and minimizing hallucinations—artifacts where the AI inaccurately modifies image content. The ISP first processes the raw sensor data, executing crucial steps like white balance and demosaicing, before DarkDiff works on the linear RGB image to denoise it and create the final sRGB image.

DarkDiff utilizes a technique known as classifier-free guidance, which dictates how closely the model should conform to the input image in contrast to its learned visual priors. Modifying this guidance enables a balance between generating smoother patterns and sharper textures, though it also heightens the risk of introducing unwanted artifacts.

## Evaluating DarkDiff

The researchers assessed DarkDiff using actual photos taken in extremely low-light situations with cameras such as the Sony A7SII. They compared the outcomes against other raw enhancement models and diffusion-based benchmarks, including ExposureDiff. The test images were captured at night with exposure times as short as 0.033 seconds, and DarkDiff’s improvements were reviewed against reference photos taken with significantly prolonged exposure times on a tripod.

## DarkDiff’s Challenges

Despite its promising capabilities, the researchers recognize that DarkDiff’s AI-driven processing is significantly slower than traditional methods, possibly requiring cloud processing to manage its high computational needs. Running the model locally on a smartphone could rapidly drain battery life. Furthermore, there are constraints regarding non-English text recognition in low-light environments.

While the study does not suggest that DarkDiff will be implemented in iPhones in the immediate future, it emphasizes Apple’s ongoing dedication to advancing computational photography—a vital area of focus in the smartphone market as consumers demand camera functionalities that exceed the physical limits of their devices.

For those interested in an in-depth exploration, the complete study and further comparisons between DarkDiff and other denoising methods can be found

Comprehending the Importance of a Blue Ethernet Cable

a router connected to a USB for my home media server, an Ethernet switch, and several gaming consoles. As I was connecting devices to the router and Ethernet switch, I observed something intriguing. The Ethernet cables I had used over the years displayed a variety of colors.

Some cables were yellow, orange, black, and even gray, but the majority were blue, which made me curious about the significance of these different colored cables. Most general connection cables typically come in two primary colors, predominantly black or white. Black serves as a common color for computers, gaming consoles, televisions, and other devices. White, being another favored color for devices, fits into a widely accepted color scheme for walls in residential spaces.

USB connections are available in various colors to indicate their features, so one might assume there’s also a rationale for Ethernet cables to exhibit different colors. However, the truth is that the colors of Ethernet cables do not convey any particular meaning, at least not in a technical context.

Ethernet cable colors have significance

VR Flourishes in 2025 as XR Glasses Increase in Popularity

A historic amount of new VR headsets were revealed, smart glasses emerged as a truly breakout segment, and prospects for XR continue to brighten.

By all indications, 2025 marked a significant year for XR. The acronym XR, which represents eXtended Reality, encompasses VR, AR, and all related technologies, forming one of the few consensus terms within the industry. The wearable face computer market expanded throughout 2025, all beginning with VR.

The past year was crucial for major VR launches, and while some of that momentum carried into 2025 with titles such as Deadpool VR, Alien: Rogue Incursion, Thief VR: Legacy of Shadows, and others, the true triumphs belonged to indie developers. This is largely because, for reasons unknown, Meta Quest players appear to favor smaller games that generate substantial buzz on social media.

A prime example is Animal Company, which attracted “over 1 billion views organically” on TikTok, as per a blog post from a Meta developer profile. This led it to secure the 5th-highest first-year revenue for a VR title, boasting over 1 million active monthly users and inspiring numerous clones. UG VR represents another success, following the same trend of free-to-play games with in-app DLC options.

This change has pleased smaller teams, yet it has also driven several businesses to shut down. Meta dismissed numerous employees across its first-party VR development studios, and we witnessed the closure of established studios like Toast Interactive and WIMO Games. The silver lining is that the Quest once again surpassed most major consoles in sales this Black Friday/Cyber Monday, according to publicly available data, a trend that has become a holiday staple over the years.

All of this culminated in early December when Meta chose to cut 30% of Reality Labs’ budget starting in January 2026, a decision that had been overdue as the department’s expenditures had spiraled out of control over the years, while other Meta divisions have faced 10% year-over-year cuts since 2022.

While that may sound negative at first, it is setting the stage for a more efficient Meta Quest. Two lead product and UI designers from Apple joined Meta in early December, and it is rumored that they will be involved in redesigning the Quest UI and crafting the Quest 4 into an ultra-light, sleek, gaming-centric headset.

This shift is also notable because Meta finally faces significant competition in the industry. Apple launched an upgraded Vision Pro with a new chipset and a more comfortable head strap in August. Additionally, Samsung has finally introduced the Galaxy XR headset alongside Android XR.

To enhance things further, we had the opportunity to test Android XR on Xreal’s Project Aura smart glasses, expected to launch in 2026. This represents a complete VR headset operating system within a pair of lightweight and comfortable smart glasses, poised to be a substantial game-changer next year.

Moreover, Valve announced a new VR headset named the Steam Frame. This headset operates on a new version of SteamOS that can run Windows VR games on a mobile chipset and also natively handle Android games. It is anticipated to create significant impact, as you might expect, in early 2026.

The year smart glasses triumphed

The VR sector has never seemed more active, but the smart glasses category has not experienced the level of success it achieved until 2025. Ray-Ban Meta Smart Glasses served as the turning point the industry required, and Meta intensified its commitment to dominate this segment for years ahead.

The company increased production of its glasses back in February, then launched a series of new glasses to raving reviews in the fall. Ray-Ban Gen 2, Oakley Meta HSTN, Oakley Meta Vanguard, and Meta Ray-Ban Display Glasses all caused significant impact, likely resulting in even more substantial sales, establishing Meta as the leading smart glasses provider after years of investing billions in research and development.

However, the standout was the Meta Ray-Ban Display Glasses. These are the first consumer-ready version of Meta’s smart glasses featuring a display, and while they come with a high price tag, they represent a crucial milestone in the smart glasses race.

This was also the year when Google began taking smart glasses seriously again. We experienced Google and Samsung’s prototype smart glasses back in May, and a subsequent Android XR event in December provided us with even deeper insights into the company’s ambitious plans for 2026.

This does not merely imply AI glasses to rival Ray-Ban and Oakley Meta smart glasses; it also indicates plans to leverage partnerships with existing smart glasses manufacturers. Magic Leap smart glasses powered by Android XR were showcased in October and will enter competition with Meta Ray-Ban Display Glasses, while Xreal Project Aura is going all-in with a complete VR UI in a stylish pair of smart glasses.
