On the surface, ChatGPT might seem like a tool that can come in useful for an array of work tasks. But before you ask the chatbot to summarize important memos or check your work for errors, it's worth remembering that anything you share with ChatGPT could be used to train the system and perhaps even pop up in its responses to other users. That's something several Samsung employees probably should have been aware of before they reportedly shared confidential information with the chatbot.

Soon after Samsung's semiconductor division started allowing engineers to use ChatGPT, workers leaked secret info to it on at least three occasions, according to The Economist Korea (as spotted by Mashable). One employee reportedly asked the chatbot to check sensitive database source code for errors, another solicited code optimization and a third fed a recorded meeting into ChatGPT and asked it to generate minutes.

Reports suggest that, after learning about the security slip-ups, Samsung attempted to limit the extent of future faux pas by restricting the length of employees' ChatGPT prompts to a kilobyte, or 1024 characters of text. The company is also said to be investigating the three employees in question and building its own chatbot to prevent similar mishaps. Engadget has contacted Samsung for comment.

ChatGPT's data policy states that, unless users explicitly opt out, it uses their prompts to train its models. The chatbot's owner OpenAI urges users not to share secret information with ChatGPT in conversations as it's “not able to delete specific prompts from your history.” The only way to get rid of personally identifying information on ChatGPT is to delete your account — a process that can take up to four weeks.

The Samsung saga is another example of why it's worth exercising caution when using chatbots, as you perhaps should with all your online activity. You never truly know where your data will end up.

Google announced end-of-life dates today for products relying on the Nest app that won’t carry over to the new Google Home. If you own any Nest Secure or Dropcam home-security products, you have a year to use them before they become paperweights. Phasing out old and incompatible hardware could signal that the arrival of Google’s more customizable new Home app is drawing near.

Nest Secure will continue to work until April 8th, 2024. To ease the blow, Google is offering some freebies to customers — as the company often does when its products head to the Google Graveyard. Nest Secure users will receive an offer for a free ADT Self Setup System (up to a $485 value); alternatively, they can opt for $200 in Google Store credit. Google says it will send an email with redemption instructions to eligible users.

Dropcam products will also cease to work after April 8th of next year. Google advises users to download and save their video history before this date to avoid losing it. As consolation for Dropcam customers, the company is offering a free Nest Cam (indoor, wired) for those with a Nest Aware subscription; those without a subscription can take 50 percent off the same camera.

Dropcam

Finally, Works With Nest, the API system allowing third-party integrations with otherwise incompatible smart home accessories, will stop working after September 29th. Google points customers to Assistant-based routines in the Google Home app as a replacement, and it plans to launch a script editor “in the coming months” to make up for other lost features. The company says it’s also “working closely” with partners to provide replacement integrations.

Google announced an updated Home app last October that could be the primary source for today’s hardware cutoff announcements. The updated Home app integrates Matter, including its Fast Pair feature. It’s available now in a public preview.

Nest Secure launched in 2017 as a fresh take on smart home security. Designed to compete with legacy brands like ADT (which Google later invested in), the system included a Guard base, motion-detecting sensors for windows and doors and tag keychains, which let you quickly enable or disable the system. Google announced in 2020 it had discontinued the platform but promised it would continue working for the foreseeable future. Meanwhile, Dropcam began as a pioneering smart home security brand, launching some of the first cloud-connected cameras. Google / Nest bought the startup in 2014 for $555 million, a move that founder Greg Duffy later described as a “mistake.”

It's Friday, which means it's time for another roundup of good tech deals. Today's highlights include Amazon's Kindle Paperwhite back down to $100, which is within $5 of the popular e-reader's all-time low. Apple's AirPods Pro are $50 off their list price at $200, while the Apple Watch SE is a good value at $219. Beyond that, we're still seeing a handful of deals on Super Mario games for the Nintendo Switch, as well as discounts on Samsung storage gear and Logitech's MX Keys Mini keyboard, among others. Here are the best tech deals from this week that you can still get today.

Amazon Kindle Paperwhite

Amazon's Kindle Paperwhite is on sale for $100, which is $5 more than the e-reader's all-time low but still $30 or so less than its usual street price. We gave the "Signature Edition" of the Paperwhite a review score of 97 in late 2021; by comparison, this model has less storage (8GB instead of 32GB), no Qi wireless charging and a slightly less advanced front light. Those shouldn't be dealbreakers, though, as the standard Paperwhite still provides a sharp 6.8-inch display that's easy on the eyes, a lightweight and waterproof design with a USB-C port and access to the same mammoth e-book library.

There are excellent alternatives here: Kobo's Clara 2E, the top pick in our guide to the best e-readers, is a similarly capable device for those who'd rather not shop in Amazon's closed-off ecosystem, while Amazon's base Kindle offers a more affordable entry point into the Kindle library. Both of those models have six-inch displays, though. if you'd prefer a larger screen and don't mind buying your e-books from Amazon, the Paperwhite is still highly comfortable — and a good value at this price.

Samsung Evo Select

Samsung's Evo Select is a dependable way to add more storage space to a Nintendo Switch, Raspberry Pi, GoPro or any other gadget that supports microSD cards. The 256GB model is currently available for $19, which is a new low. This V30- and U3-rated card isn't the absolute fastest you can buy, but it's quick enough to run games and record 4K video with minimal issues, and it's backed by a 10-year warranty. Most importantly, it's affordable. For reference, this variant typically retails around $25.

Nintendo Switch game sale

A handful of deals from Nintendo's Mario Day sale last month are scheduled to end on Saturday, but recommended games like Super Mario 3D World + Bowser's Fury, Super Mario Odyssey, Mario Kart 8 Deluxe, Super Mario Maker 2, and New Super Mario Bros. U Deluxe are still down to $40 for now. While these are not massive discounts, they bring each game about $10-15 lower than usual. Nintendo is still fairly stingy when it comes to discounting first-party Switch games, so if this week's release of the The Super Mario Bros. Movie has you itching for more Mario at home, this is a decent chance to save.

Nintendo has a few other Switch game deals of note going on this week. The acclaimed FPS games Doom and Doom Eternal are down to all-time lows of $10 and $13, respectively, while a bundle that pairs the beloved RPGs Persona 3 Portable and Persona 4 Golden is $10 off at $30. The latter is the first discount we've seen for those Switch ports. Portal Companion Collection, which includes the classic first-person puzzler Portal and its co-op-friendly sequel Portal 2, is down to a low of $12 as well.

Logitech MX Keys Mini

Logitech's MX Keys Mini is a compact wireless keyboard we recommend in our guide to the best iPad accessories. It has a slim profile, but its backlit and well-spaced keys are more comfortable to type on than most portable keyboards we've tested. Typically priced around $100, the MX Keys Mini is currently available for $66 at Lenovo when you use the code EXTRA5 in your cart prior to checkout. This deal technically applies to the Business version of the device, which means it comes with a different USB receiver that isn't compatible with many older Logitech devices. However, the keyboard can still pair with and quickly swap between three separate devices over Bluetooth. 

Apple AirPods Pro

We've seen Apple's AirPods Pro fall to $200 multiple times in recent months, but this discount still comes within a dollar of the lowest price we've seen. Normally, the noise-cancelling earbuds go for around $225. We gave the second-gen AirPods Pro a score of 88 in our review last year, and they're currently the "best for iOS" pick in our guide to the best wireless earbuds. There are more well-rounded pairs out there with better battery life and mic performance, but Apple's in-ears still deliver impressive ANC and sound quality, and they're particularly easy to use with other Apple devices.

Samsung Galaxy S23

The unlocked, 128GB version of Samsung's Galaxy S23 is down to $700, which is a $100 discount for a phone that launched in February. The S23 isn't a top pick in our guide to the best smartphones, and it's not as strong of a value as Google's Pixel 7, but it's worth considering if you specifically want a smaller handset with flagship-level features. It's fast and well-built, and its 6.1-inch, 120Hz OLED display should be smooth and vibrant. The camera isn't top-tier in low-light settings but still far from poor overall, and Samsung is promising four years of OS upgrades, with an extra year of security updates. 

The S23 isn't the phone to buy for battery life, though, as its smaller size means there's less space for a battery that can last longer than a day. We gave the 6.6-inch Galaxy S23+ a review score of 86 earlier this year: Apart from the larger frame, that phone comes with twice as much storage by default, faster charging support and a bigger battery, but the two devices are otherwise similar. 

Fully Cora standing desk converter

The Fully Cora is a simple standing desk converter that we've previously recommended. It's meant more for a laptop and a handful of accessories than a full keyboard and monitor setup, but if you just want a way to sit less while working, it's a relatively unobtrusive, lightweight and easy-to-adjust tool for doing that. The device is currently available for $90 as part of a wider sale at Fully's online store. It's technically been at this price for a few weeks, but it's still half off Fully's MSRP. Just note that you may have to invest in a separate stand to keep your laptop at a more comfortable eye level. 

Apple Watch SE

The Apple Watch SE has dropped to $219, which is within $10 of the lowest price we've seen. This isn't the first time we've seen the smartwatch hit this price, but it's still $30 below Apple's MSRP. We gave the latest SE a review score of 89 last September, and we currently recommend it for first-time and budget-conscious wearable buyers in our guide to the best smartwatches. 

Compared to the pricier Apple Watch Series 8, the top pick in our guide, the SE lacks an always-on display mode, fast charging and premium features like a skin temperature sensor, ECG monitor and blood oxygen sensor. Its display is a smidge smaller, too. That said, it still provides most of the core Apple Watch feature set for way less money, with support for notifications, heart-rate monitoring and crash detection. It also uses the same processor as the Series 8, so it doesn't feel slow in everyday use. 

Samsung 980 Pro SSD with Heatsink

The 1TB model of Samsung's 980 Pro SSD with an integrated heatsink is on sale for $87, which is a new all-time low. On average, the device has run closer to $120 in recent months, though its price has steadily dipped over time. We recommend this speedy PCI Express 4.0 drive in our guide to the best SSDs for the PS5, as it meets Sony's strict requirements for upgrading that console's storage. 

It's best if you buy the 980 Pro for that specific purpose, though. If you simply want a new SSD for an aging PC and don't care about gaming, a less expensive PCIe 3.0 drive should be a better value. For that market, SK Hynix's Gold P31 is a well-regarded option that's currently down to $72 for a 1TB model.

Apple + Target gift card bundle

Here's a simple one: If you buy a $100 Apple gift card at Target, the retailer will throw in a $10 Target gift card for no extra cost. As a reminder, an Apple gift card can be used on purchases at the company's physical retail shops, the App Store and Apple services like iCloud and Apple Music. Target has run this promotion several times before, but if you plan on shopping at Apple and Target in the near future anyway, it's effectively a bit of free money. Target says the offer will end on April 8. 

Blue Yeti Nano

The grey model of the Blue Yeti Nano is on sale for $53 at Amazon. Outside of a very brief drop to $50 last year, that's the lowest price we've tracked. The Yeti Nano is a compact USB microphone we've recommended in the past. There are certainly clearer-sounding options for those looking to get into more professional recordings, but if you just want a mic upgrade for your work calls that's easy to set up and won't take up a ton of room on your desk, the Yeti Nano is a decent value when it's discounted to this extent. If space is less of a concern, note that the standard Yeti is down to $80; that mic is bigger but sounds better and offers more pickup patters to accommodate different types of recordings. 

Amazon Fire TV Stick 4K Max

Amazon's Fire TV Stick 4K Max is back down to $35, matching the lowest price we've tracked. The 4K media player has regularly bounced between this deal price and its MSRP of $55 in recent months, but for less than $40 it's a good value for those who want to add more streaming services to their TV. The device itself is reasonably fast and supports most of the major apps and HDR formats. (Compared to the standard Fire TV Stick 4K, the speed upgrade is enough to make the 4K Max a better buy.) It has voice search functionality built into its remote, which is convenient. For tinkerers, it's also easier to sideload unsupported apps here than it is with similarly priced streamers. 

The caveat is that the Fire TV UI tends to advertise Amazon's own content over shows and search results from other apps. That means the 4K Max will work best if you regularly use Amazon services like Alexa and Prime Video. If you aren't as beholden to Amazon, Roku's Streaming Stick 4K and Google's Chromecast are close alternatives that we recommend in our guide to the best streaming devices. The former has a simpler and more neutral interface, while the latter is generally more accurate at searching and better about personalizing its UI to your viewing habits.

Ninja DZ401 Foodi air fryer

Ninja's DZ401 Foodi is the "best dual-zone" pick in our guide to the best air fryers, offering two baskets that allow you to cook two foods in two different ways at the same time. Not everyone needs something this hefty, but if you often have to cook for a large family, it can be useful. The 10-quart model is down to $180, which is roughly $20 below its usual going rate. The device dropped as low as $130 during the holidays last year, but this discount matches the lowest price we've seen in 2023. 

Master & Dynamic MW75

A recommendation from our guide to the best wireless headphones, Master & Dynamic's MW75 is on sale for $419 with the checkout code GIVEGET30. Normally, this noise-cancelling pair goes for $599. Even at 30 percent off, it's hard to call the MW75 a great value, as its ANC can't really match less expensive alternatives like the Sony WH-1000XM5 or Bose QuietComfort 45. But the pair stands out for its decidedly upscale design, which uses a premium-feeling blend of leather, aluminum and tempered glass. It sounds nice as well, though some may prefer a bit less treble presence by default. 

Either way, we don't see the MW75 drop this low very often, so if you've got cash to burn and are particular about aesthetics, it's worth considering. The code above is applicable to various other Master & Dynamic headphones as well; the company says the sale will run through April 10.

AI Chatbots are relatively old by tech standards, but the newest crop — led by OpenAI's ChatGPT and Google's Bard — are vastly more capable than their ancestors, not always for positive reasons. The recent explosion in AI development has already created concerns around misinformation, disinformation, plagiarism and machine-generated malware. What problems might generative AI pose for the privacy of the average internet user? The answer, according to experts, is largely a matter of how these bots are trained and how much we plan to interact with them

In order to replicate human-like interactions, AI chatbots are trained on mass amounts of data, a significant portion of which is derived from repositories like Common Crawl. As the name suggests, Common Crawl has amassed years and petabytes worth of data simply from crawling and scraping the open web. “These models are training on large data sets of publicly available data on the internet,” Megha Srivastava, PhD student at Stanford's computer science department and former AI resident with Microsoft Research, said. Even though ChatGPT and Bard use what they call a "filtered" portion of Common Crawl's data, the sheer size of the model makes it "impossible for anyone to kind of look through the data and sanitize it,” according to Srivastava.

Either through your own carelessness or the poor security practices by a third-party could be in some far-flung corner of the internet right now. Even though it might be difficult to access for the average user, it's possible that information was scraped into a training set, and could be regurgitated by that chatbot down the line. And a bot spitting out someone's actual contact information is in no way a theoretical concern. Bloomberg columnist Dave Lee posted on Twitter that, when someone asked ChatGPT to chat on encrypted messaging platform Signal, it provided his exact phone number. This sort of interaction is likely an edge case, but the information these learning models have access to is still worth considering. "It’s unlikely that OpenAI would want to collect specific information like healthcare data and attribute it to individuals in order to train its models," David Hoelzer, a fellow at security organization the SANS Institute, told Engadget. “But could it inadvertently be in there? Absolutely.”

Open AI, the company behind ChatGPT, did not respond when we asked what measures it takes to protect data privacy, or how it handles personally identifiable information that may be scraped into its training sets. So we did the next best thing and asked ChatGPT itself. It told us that it is "programmed to follow ethical and legal standards that protect users’ privacy and personal information" and that it doesn't "have access to personal information unless it is provided to me." Google for its part told Engadget it programmed similar guardrails into Bard to prevent the sharing of personally identifiable information during conversations.

Helpfully, ChatGPT brought up the second major vector by which generative AI might pose a privacy risk: usage of the software itself — either via information shared directly in chatlogs or device and user information captured by the service during use. OpenAI’s privacy policy cites several categories of standard information it collects on users, which could be identifiable, and upon starting it up, ChatGPT does caution that conversations may be reviewed by its AI trainers to improve systems. 

Google's Bard, meanwhile, does not have a standalone privacy policy, instead uses the blanket privacy document shared by other Google products (and which happens to be tremendously broad.) Conversations with Bard don't have to be saved to the user's Google account, and users can delete the conversations via Google, the company told Engadget. “In order to build and sustain user trust, they're going to have to be very transparent around privacy policies and data protection procedures at the front end,” Rishi Jaitly, professor and distinguished humanities fellow at Virginia Tech, told Engadget.

Despite having a "clear conversations" action, pressing that does not actually delete your data, according to the service’s FAQ page, nor is OpenAI is able to delete specific prompts. While the company discourages users from sharing anything sensitive, seemingly the only way to remove personally identifying information provided to ChatGPT is to delete your account, which the company says will permanently remove all associated data.

Hoelzer told Engadget he’s not worried that ChatGPT is ingesting individual conversations in order to learn. But that conversation data is being stored somewhere, and so its security becomes a reasonable concern. Incidentally, ChatGPT was taken offline briefly in March because a programming error revealed information about users’ chat histories. It's unclear this early in their broad deployment if chat logs from these sorts of AI will become valuable targets for malicious actors.

For the foreseeable future, it's best to treat these sorts of chatbots with the same suspicion users should be treating any other tech product. “A user playing with these models should enter with expectation that any interaction they're having with the model," Srivastava told Engadget, "it's fair game for Open AI or any of these other companies to use for their benefit.”

Samsung has warned of plummeting profits and plans to cut back on memory chip production in response to falling demand, The Korea Herald has reported. It expects to earn just 600 billion won ($455 million) for the first quarter of 2023, a drop of 96 percent from the same period last year. It blamed falling demand for memory chips, a situation that could be a bad sign for the tech industry as a whole. 

"We’re adjusting to lower memory production to a meaningful level... in addition to optimizing line operations that are already underway,” Samsung said in a statement. It added that it would continue to invest in clean room infrastructure and expand R&D spending, as it sees improved memory chip demand in the mid- to long-term. 

Although it trails Taiwan's TSMC in other areas, Samsung is the global leader in DRAM and NAND flash memory chip production with 40.7 and 31.4 percent shares respectively. Such chips are used in consumer devices of all kinds, ranging from smartwatches to mobile phones and laptops. The oversupply of memory chips is therefore a sign that demand for such products has fallen significantly due to an ongoing global economic slowdown. 

The slowdown comes just a short time after one of the biggest tech industry booms of all time, powered by the COVID-19 pandemic. Since late in 2021, however, memory prices have dropped through the floor, with DRAM and NAND prices down by 20 and 15 percent in just the last quarter alone. One bright spot for Samsung has been sales of its new Galaxy S23 smartphone, which helped bolster profits, the company said. It will reveal more details in its earnings report set to drop at the end of April. 

Apple's Mac Mini M2 computers are the cheapest way to get the company's latest processors, and now Amazon is offering them at the lowest prices we've ever seen. You can buy the 256GB version for just $500 ($100 off the regular price) and the 512GB model for $690, or $110 off — both all-time lows. 

In our Engadget review, we gave the Mac Mini a solid score of 86, lauding the performance and classic aluminum design. It's tiny but mighty, with the M2 processor easily powerful enough for productivity chores and multitasking. The chip combines computing operations, like CPU, GPU, input/output interfaces and certain memory processes into one "system on a chip," allowing for faster processing speeds.

On top of that, you get killer connectivity, with two Thunderbolt 4 USB-C connections, HDMI 2.0 (with 4K 240Hz and 8K 60Hz output), two USB-A ports, a headphone jack and gigabit Ethernet (upgradeable to 10 gigabit). The M2 Pro model adds two additional USB-C ports, making it even more useful for creatives with a ton of accessories.

The Mac Mini M2 won't replace your gaming machine, but it can handle nearly everything else you throw at it. We wouldn't recommend the overpriced storage or RAM upgrades either, as the M2 is much more efficient with RAM than typical PCs. Still, if you're looking for a cheap but powerful Mac, this is the way to go.

Google will soon start rolling out WebGPU, a new feature that will allow Chrome browsers to use your graphics card to accelerate games, graphics and AI, the company announced. It'll be enabled by default in Chrome 113 set to arrive in a few weeks for Windows PCs (via Direct3D 12), MacOS (Metal) and ChromeOS (Vulkan).

WebGPU will give web apps better access to your graphics card, Google said, allowing developers to achieve the same level of graphics with far less code. That could make for new and interesting Chrome browser-based 3D apps, and without a doubt, better games. 

At the same time, it will power over "three times improvements in machine learning model inferences," the company added. That could pave the way for machine learning apps that run locally, like NVIDIA Broadcast's strange "eye contact" feature. 

Google calls the initial release a "building block for future updates and enhancements," as developers begin to dig into it and create new applications. The API has been in development for over six years, and should be available to Firefox and Safari down the road (Edge often gets features at the same time as Chrome), and expand to more operating systems like Android. You can try the feature for yourself if you're on the Chrome Beta track using a demo called Babylon.js, which already offers full WebGPU support. 

Twitter has finally shut off its free API and, predictably, it’s breaking a lot of apps and websites. The company had previously said it would cut off access in early February, but later delayed the move without providing an updated timeline.

But, after announcing its new paid API tiers last week, the company seems to have started cutting off the thousands of developers relying on its free developer tools. Over the last couple days, a number of app makers and other services have reported that the Twitter API is no longer functioning. Mashable reported the shutoff seems to have started Tuesday morning, though many developers are still trying to understand what’s happening as Twitter doesn’t seem to have communicated with most developers about the changes.

The ending of Twitter’s free API comes after the company abruptly changed its rules to ban third-party Twitter clients as part of a larger shakeup of its developer strategy. But, as we’ve previously reported, third-party clients were only a small fraction of the developers, researchers, bot makers and others who relied on Twitter’s APIs.

For example, apps and websites that used Twitter’s API to enable sharing of content to and from Twitter are now seeing that functionality break. WordPress reported Tuesday that it was no longer able to access the API, rendering its websites unable to automatically share posts to Twitter. (The issue has since been fixed, according to the company.)

Likewise, Echobox, a service that allows publishers to share content on Twitter, said on Wednesday it was also disconnected from the Twitter API “without warning.” The company said it found a workaround, but hadn’t heard from Twitter. News reading app Flipboard, which recently began shifting its focus to Mastodon, also warned that anyone who used Flipboard to view Twitter feeds would soon see the feature disabled.

Many of Twitter’s bot developers are also impacted. The maker of “Cheap Bots Done Quick,” which allows people to create bots for Twitter, reported receiving a notice that they were cut off from the API. Twitter has said that its new “basic” tier is meant to provide a pathway to allow bots to continue, but many developers have said the monthly limit of 1,500 tweets is too constrained.

Newsletter platform Substack is also having issues using embedded tweets, though it’s unclear if this is related to the API shutdown or the company recently announcing a potential Twitter competitor. (Embeds seem to be functioning normally on other websites, including this one.)

All of these issues are further complicated by the fact that Twitter seems to have communicated very little with any of its developers about these changes or what they mean. Most of the employees who worked in developer relations were cut during the company’s mass layoffs. And the company’s developer forums are filled with posts from confused developers looking for answers. The company no longer has a communications team, and its press email auto-responds with a poop emoji.

As Mashablepoints out, the shutoff has even affected developers who are willing to pay for Twitter’s API, even though pricing for higher-level enterprise tiers is still unclear. “When Twitter announced these new tiers last week, we immediately sought to sign up for the Enterprise tier,” Echobox wrote in a blog post on Wednesday. “ We still have had no response from Twitter’s enterprise sales team and our access to the API was cut off without notice yesterday.”

News app Tweet Shelf said its API access had also been suspended despite applying for Enterprise API access. So did TweetDeleter, a service for automatically deleting tweets, and Tweet Archivist an analytics tool. 

But it’s still unclear how many developers will be able to continue using Twitter’s API in some form. The free and $100/month “basic” tier are extremely limited compared to what was previously offered for free. And, while Twitter hasn’t revealed exactly how much the “enterprise” level will cost, many are expecting it to be prohibitively expensive – rumors have suggested it could cost $40,000 a month or more.

Some developers aren’t even waiting to find out the pricing details. The developer of Social Bearing, an analytics service used by researchers, said there was no way the service could continue to run. “I wish those of you left at Twitter and fellow devs the best of luck,” they tweeted.

A Cornell University researcher has developed sonar glasses that “hear” you without speaking. The eyeglass attachment uses tiny microphones and speakers to read the words you mouth as you silently command it to pause or skip a music track, enter a passcode without touching your phone or work on CAD models without a keyboard.

Cornell Ph.D. student Ruidong Zhang developed the system, which builds off a similar project the team created using a wireless earbud — and models before that which relied on cameras. The glasses form factor removes the need to face a camera or put something in your ear. “Most technology in silent-speech recognition is limited to a select set of predetermined commands and requires the user to face or wear a camera, which is neither practical nor feasible,” said Cheng Zhang, Cornell assistant professor of information science. “We’re moving sonar onto the body.”

The researchers say the system only requires a few minutes of training data (for example, reading a series of numbers) to learn a user’s speech patterns. Then, once it’s ready to work, it sends and receives sound waves across your face, sensing mouth movements while using a deep learning algorithm to analyze echo profiles in real time “with about 95 percent accuracy.”

Ruidong Zhang / Cornell University

The system does this while offloading data processing (wirelessly) to your smartphone, allowing the accessory to remain small and unobtrusive. The current version offers around 10 hours of battery life for acoustic sensing. Additionally, no data leaves your phone, eliminating privacy concerns. “We’re very excited about this system because it really pushes the field forward on performance and privacy,” said Cheng Zhang. “It’s small, low-power and privacy-sensitive, which are all important features for deploying new, wearable technologies in the real world.”

Privacy also comes into play when looking at potential real-world uses. For example, Ruidong Zhang suggests using it to control music playback controls (hands- and eyes-free) in a quiet library or dictating a message at a loud concert where standard options would fail. Perhaps its most exciting prospect is people with some types of speech disabilities using it to silently feed dialogue into a voice synthesizer, which would then speak the words aloud.

If things go as planned, you can get your hands on one someday. The team at Cornell’s Smart Computer Interfaces for Future Interactions (SciFi) Lab is exploring commercializing the tech using a Cornell funding program. They’re also looking into smart-glasses applications to track facial, eye and upper body movements. “We think glass will be an important personal computing platform to understand human activities in everyday settings,” said Cheng Zhang.

If you've been looking to scoop up a new gaming laptop but a solitary screen doesn't quite cut the mustard, you should perhaps consider the ASUS ROG Zephyrus Duo 16. It's our current pick for the best gaming laptop with dual displays. Best of all, it's on sale right now. One variant is available for $2,700, which is a whopping $800 off the regular price.

This configuration comes with a 16-inch, 165Hz ROG Nebula HDR QHD 16:10 display. It's powered by an AMD Ryzen 9 6900HX CPU and NVIDIA GeForce RTX 3070 Ti GPU. The 32GB of DDR5 RAM should help ensure you can play most games without too many hitches. You'll have a decent volume of storage space for your games too, as this ASUS ROG Zephyrus Duo 16 has a 1TB SSD.

The internal specs aren't what make this gaming laptop stand out, though. It's that second screen that sits between the keyboard and the main display. The 14-inch ScreenPad Plus could be handy for productivity, allowing you to keep an eye on certain apps while keeping most of your focus on more important tasks up top. 

It might help you keep tabs on the news, social media or a show you're watching while getting some work done. Or you might use it to keep Discord open while you play games or pull up a walkthrough on YouTube if you get stuck. Alternatively, you could use it to monitor your viewership stats while you stream your gameplay.

We gave the ASUS ROG Zephyrus Duo 16 a score of 86 in our review, which is certainly respectable. The device isn't all sunshine and roses, unfortunately.
