YouTube announced two new experimental generative AI features on Monday. YouTube Premium subscribers can soon try AI-generated comment summaries and a chatbot that answers your questions about what you’re watching. The features will be opt-in, so you won’t see them unless you’re a paid member who signs up for the experiments during their test periods.

The AI-powered summaries will organize comments into “easily digestible themes.” In a Mr. Beast video YouTube used as an example, the tool generated topics including “People love Bryan the bird,” “Lazarbeam should be in more videos,” “No submarine” and “More 7 day challenges.” You can tap on the topic to view the complete list of associated comments. The tool will only run “on a small number of videos in English” with large comment sections.

If you’re worried about YouTube’s summaries spiraling out of control the way the platform’s comment sections often do, the company says it won’t pull content from unpublished messages, those held for review, any containing blocked words or those from blocked users. Further, creators can use the tool to delete individual comments if they see problematic (or otherwise unwanted) discussions about their videos.

Meanwhile, YouTube’s conversational AI tool gives you a chatbot trained on whichever video you’re watching. Generated by large language models (LLMs), the assistant lets you “dive in deeper” by asking questions about the content and fishing for related recommendations. The company says the AI tool, which appears similar to chatting with Bard, draws on info from YouTube and the web, providing answers without interrupting playback. Eligible users can find it under a new “Ask” button in the YouTube app for Android.

Starting today, YouTube Premium subscribers can opt into the comment summarizer on YouTube’s experiments page. However, the company says you won’t see the “Topics” option for all videos. In addition, the conversational AI tool is only available now “to a small number of people on a subset of videos,” but YouTube Premium subscribers with Android devices will be able to sign up to try it in the coming weeks. The company warns the experimental features “may not always get it right,” a description that can equally apply to Google’s other AI experiments.

A Parkinson’s patient can now walk 6km (3.7 miles) thanks to an implant targeting the spinal cord. The Guardian reports that the man — 62-year-old “Marc” from Bordeaux, France — developed severe mobility impairments from the degenerative disease. “I practically could not walk anymore without falling frequently, several times a day,” he said in a press release announcing the breakthrough. “In some situations, such as entering a lift, I’d trample on the spot, as though I was frozen there, you might say.” Wearing the spinal implant allows him to walk “almost normally” as the research team eyes a full clinical trial.

Marc underwent a “precision neurosurgical procedure” two years ago at Lausanne University Hospital (CHUV), which helped facilitate the research. The surgery fitted him with an electrode field placed against his spinal cord and an electrical impulse generator under the skin of his abdomen. Although conventional Parkinson’s treatments often target brain regions affected by the loss of dopamine-producing neurons, this approach instead focuses on the spinal area associated with activating leg muscles for walking.

The procedure used a personalized map of Marc’s spinal cord, identifying the specific locations signaling leg movements. He wears a movement sensor on each leg that tells the implant he’s trying to walk; it then switches on and sends electrical impulses to the targeted spinal neurons, adapting to his movement in real-time.

“In response to precise stimulation of the lumbar spinal cord, I’ve observed for the first time remarkable improvements of gait deficits due to Parkinson’s disease,” project supervisor Jocelyne Bloch, professor and neurosurgeon at CHUV Lausanne University hospital, said in a webinar discussing the patient’s success. “I really believe that these results open realistic perspectives to develop a treatment.”

The patient says he could walk practically normally with the stimulation after several weeks of rehab. He now wears it for around eight hours daily, only turning it off when sleeping or lying down for a while. “I turn on the stimulation in the morning and I turn off in the evening,” he said. “This allows me to walk better and to stabilise. Right now, I’m not even afraid of the stairs anymore. Every Sunday I go to the lake, and I walk around 6 kilometres. It’s incredible.”

The researchers caution that there’s still a vast chasm between tailoring the approach to one person vs. optimizing it for wide-scale use. Co-leads Grégoire Courtine and Bloch are working on a commercial version of the neuroprosthetic in conjunction with Onward Medical. “Our ambition is to provide general access to this innovative technology to improve the quality of life of Parkinson’s patients significantly, all over the world,” they said.

Michael J. Fox Foundation

In the meantime, research on six new patients will continue in 2024. The team says a “generous donation” of $1 million from the Michael J. Fox Foundation for Parkinson’s Research is funding the upcoming work. In 2021, the actor’s organization announced it had contributed over $1.5 billion to Parkinson’s research.

At least 15 visitors at Yuga Labs’ Apefest, a celebration of the marvels of Bored Ape Yacht Club NFTs, may have experienced serious eye injuries. Bloomberg reports that multiple people attending the NFT event in Hong Kong last weekend say they experienced vision problems, which they suspect stemmed from the event’s stage lighting. Some of the attendees claim doctors subsequently diagnosed them with photokeratitis (aka “welder’s eye”), caused by exposure to ultraviolet (UV) light.

“Woke up in the middle of the night after Apefest with so much pain in my eyes that I had to go to the hospital,” the user Crypto June posted on X (via Coin Telegraph). “Doctor told me it was due to the UV from stage lights.” User @docwagmi suspected that the “ape friends” reporting problems appeared to have been “up close with us front stage.”

Meanwhile, Adrian Zduńczyk wrote on X, “To all my friends who suffer now: go get your eyes checked. You’ve likely most literally got your eyes burnt with UV like I did, which requires medications, eye drops, eye protection, antibiotics and specialist care. Don’t ignore this health hazard. Without proper treatment, it may cause long lasting vision impairment and other serious damage.” Zduńczyk wrote that seeking medical attention quickly appears to have spared him long-term damage. “My vision was tested as close to perfect with no serious cornea damage, luckily.”

Yuga Labs briefly addressed the issue on X, saying it’s “aware of the eye-related issues that affected some of the attendees of ApeFest,” while claiming it’s “proactively reaching out to individuals since yesterday to try and find the potential root causes.” The company downplayed the number of people reporting issues, adding, “Based on our estimates, we believe that much less than 1% of those attending and working the event had these symptoms.” The NFT company advised attendees experiencing symptoms to “seek medical attention just in case.”

X users seemed none too pleased with Yuga Labs’ PR response:

The potentially dangerous incident echoes one in 2017 when attendees of a HypeBeast party reported eye damage. The event’s DJ later reported that the lighting contractor used Philips bulbs that emit UV-C, often used as a disinfectant.

NYU is launching a project to spur the development of immersive 3D video for dance education — and perhaps other areas. Boosted by a $1.2 million four-year grant from the National Science Foundation, the undertaking will try to make Point-Cloud Video (PCV) tech viable for streaming.

A point cloud is a set of data points in a 3D space representing the surface of a subject or environment. NYU says Point-Cloud Video, which strings together point-cloud frames into a moving scene, has been under development for the last decade. However, it’s typically too data-intensive for practical purposes, requiring bandwidth far beyond the capabilities of today’s connected devices.

The researchers plan to address those obstacles by “reducing bandwidth consumption and delivery latency, and increasing power consumption efficiency so that PCVs can be streamed far more easily,” according to an NYU Engineering blog post published Monday. Project leader Yong Liu, an NYU electrical and computer engineering professor, believes modern breakthroughs make that possible. “With recent advances in the key enabling technologies, we are now at the verge of completing the puzzle of teleporting holograms of real-world humans, creatures and objects through the global Internet,” Liu wrote on Monday. 

ChatGPT maker OpenAI launched a model last year that can create 3D point clouds from text prompts. Engadget reached out to the project leader to clarify whether it or other generative AI tools are part of the process, and we’ll update this article if we hear back.

The team will test the technology with the NYU Tisch School of the Arts and the Mark Morris Dance Group’s Dance Center. Dancers from both organizations will perform on a volumetric capture stage. The team will stream their movements live and on-demand, offering educational content for aspiring dancers looking to study from high-level performers — and allowing engineers to test and tweak their PCV technology.

The researchers envision the work opening doors to more advanced VR and mixed reality streaming content. “The success of the proposed research will contribute towards wide deployment of high quality and robust PCV streaming systems that facilitate immersive augmented, virtual and mixed reality experience and create new opportunities in many domains, including education, business, healthcare and entertainment,” Liu said.

“Point-Cloud Video holds tremendous potential to transform a range of industries, and I’m excited that the research team at NYU Tandon prioritized dance education to reap those benefits early,” said Jelena Kovačević, NYU Tandon Dean.

Bungie has reportedly laid off an unknown number of staffers and delayed two highly anticipated games. Bloomberg’s Jason Schreier reports that the studio’s CEO, Pete Parsons, warned staffers they would hear “some news today” while announcing a team meeting later on Monday to “discuss today’s events.”

Meanwhile, the studio has reportedly delayed the Destiny 2 expansion, The Final Shape, and the studio’s next game, Marathon. Sony completed its deal last year to buy Bungie for $3.6 billion.

According to Bloomberg, Bungie delayed Destiny 2: The Final Shape to June from its original target of February 27, 2024. While not necessarily the end of Destiny 2, the expansion will serve as a resolution, wrapping up its main story’s loose ends. In addition, the studio has pushed back the release date for extraction shooter Marathon to 2025. That title, rebooting an IP from a 1990s Mac cult classic, is Bungie’s attempt to re-establish itself as a force in the modern gaming industry beyond Destiny.

Sony has joined much of the gaming industry (and the tech world at large) in laying off staff this year. Naughty Dog, Media Molecule and PlayStation’s Visual Arts support team have all faced cuts recently. In addition, Epic Games cut around 900 staff members in September, and CD Projekt Red announced in July it would lay off about 100 people. Niantic, Telltale, EA and Unity have also let go of workers in 2023.

Engadget has reached out to Bungie to try to confirm the layoffs and delays. We’ll update this article if we hear back.

Meta’s Oversight Board announced today it has upheld the company’s decision to leave up two posts detailing a Thai woman’s fruit juice-only diet. However, the board recommended the company restrict the monetization of similar “extreme and harmful diet-related content” on Facebook as researchers continue to wrestle with the concerning relationship between social media and eating disorders.

The Oversight Board’s decision describes the videos, posted in late 2022 and 2023 by the same account — and flagged by users as harmful. The clips detailed “content on life, culture and food in Thailand.” In both problematic videos, a man interviews a woman in Italian about her experience with “a diet consisting only of fruit juice.”

The decision illustrates the videos’ concerning influence. “In the first video, the woman says she has experienced increased mental focus, improved skin and bowel movement, happiness and a ‘feeling of lightness’ since starting the diet, while she also shares that she previously suffered from skin problems and swollen legs,” the board’s summary reads. “She brings up the issue of anorexia but states her weight has normalized, after she initially lost more than 10 kilograms (22 pounds) due to her dietary changes.”

The second video, posted around five months later, follows up on the woman’s story, asking how she feels nearly a year into her dangerous diet. “She responds by saying she looks young for her age, that she has not lost any more weight except for ‘four kilos of impurities,’ and she encourages him to try the diet.” Making matters worse, she told the interviewer she planned to become a “fruitarian” after wrapping up the fast, adding that she may start a “pranic journey,” which she describes as “living ‘on energy’ in place of eating or drinking regularly.”

Meta

The videos have been viewed over two million times and have over 15,000 comments. The posts also shared details about the woman’s Facebook page, which received a significant uptick in engagement after the second post. “Based on research commissioned by the Board, the woman’s Facebook page has 17,000 followers and features content about the lifestyle of the woman, including her diet,” the board wrote. Both the content creator and the woman’s Facebook page were part of Meta’s Partner Monetization Program, allowing them to profit from the potentially harmful advice. 

After users reported the videos, Meta’s human reviewers determined the posts didn’t violate Facebook’s Suicide and Self-Injury Community Standard. They remained visible on Facebook. Separate users for each video then appealed the decision to Meta’s Oversight Board.

The board’s decision not to remove the videos was more about the lack of specific violations of the Suicide and Self-Injury Community Standard than a belief that the content was harmless. Specifically, the videos don’t provide “instructions for drastic and unhealthy weight loss when shared together with terms associated with eating disorders,” nor do they “promote, encourage, coordinate, or provide instructions for eating disorders.” Even the woman’s mention of an energy-only “pranic journey” was determined to be “descriptive in nature” without mention of weight loss.

The board recommended Meta adjust its monetization policies to “better meet its human rights responsibilities” related to “harmful diet-related content.” Most of the board considers the current authorization of this content “a conspicuous and concerning one.”  

“With health and communications experts noting the ability of influencers to use first-hand narration styles to secure high engagement with their content — coupled with the ubiquity of wellness influencers — it is important that Meta should not provide financial benefits to create this type of content,” the board wrote.

Some board members believed demonetization of this type of content was a bridge too far. “For a minority of the Board, since demonetization may negatively impact expression on these issues, Meta should explore whether demonetization is the least intrusive means of respecting the rights of vulnerable users,” the board wrote. Meanwhile, another minority believed demonetization doesn’t go far enough. “For a separate minority of Board Members, demonetization is necessary but not sufficient; they find that Meta should additionally restrict extreme and harmful diet-related content to adults over the age of 18, and explore other measures such as putting a label on the content, to include reliable information on the health risks of eating disorders.”

Meta says that because the board upheld Meta’s decision to leave up both posts, it “will take no further action related to this bundle or the content.” The company adds that it will review the demonetization recommendation. A Meta spokesperson told Engadget it will respond to “their full recommendations in our Transparency Center” within 60 days.

Vice president Prabhakar Raghavan testified Friday that Google paid $26.3 billion in 2021 for the purpose of maintaining default search engine status and acquiring traffic, Bloomberg reports. It's likely the lion’s share of that sum went to Apple, which it has showered with exorbitant sums for many years in order to remain the default search option on iPhone, iPad and Mac.

Raghavan, who was testifying as part of the DOJ's ongoing antitrust suit against the company, said Google’s search advertising made $146.4 billion in revenue in 2021, which puts the $26 billion it paid for default status in perspective. The executive clarified that default status was the most costly part of what it pays to acquire traffic.

Raghavan didn’t mention how much of the $26.3 billion went to Apple. But CNBC reports that an estimate from private wealth management firm Bernstein ballparked that Google could pay Apple up to $19 billion this year for the default privilege.

A slide shown in court revealed that, in 2014, Google brought in $47 billion in search revenue while paying $7.1 billion for default status. Raghavan testified that Google’s overall default search engine payments nearly quadrupled from 2014 to 2021, while its search advertising revenue (roughly) tripled.

Google objected to making the figures public, arguing it would hurt its ability to negotiate future contracts. Judge Amit Mehta, overseeing the case, disagreed.

On Thursday, the US International Trade Commission (ITC) upheld a judge’s earlier ruling that the Apple Watch violated patents from medical technology company Masimo, as reported by Reuters. Although the ITC’s order could theoretically lead to an eventual import ban on Apple Watch models, the iPhone maker still has ample opportunity to avoid that outcome.

The decision stems from a lawsuit Masimo filed in 2021, accusing Apple of infringing on the smaller company’s patents related to light-based blood-oxygen monitoring. Apple introduced the feature in the Apple Watch Series 6, its 2020 flagship smartwatch. Its 2023 models, including the Apple Watch Series 9 and Apple Watch Ultra 2, still include blood-oxygen sensors.

Masimo’s filing focuses on the Apple Watch Series 6, which the iPhone maker discontinued in 2021 following the launch of its successor. It isn’t clear whether or to what degree a hypothetical import ban would affect Apple’s latest versions of its flagship wearable. A federal jury took up Masimo’s allegations earlier this year, ending in a mistrial.

The case now moves to the White House as the Biden administration has 60 days to decide whether to veto the import ban based on policy concerns. Reuters notes that US Presidents have rarely rejected bans historically. If Biden opts not to veto, Apple can appeal the ban to the US Court of Appeals for the Federal Circuit after the White House’s review period expires. Other options for the $2.6 trillion company include settling with Masimo or issuing software updates that skirt the patent.

Masimo paints the scenario as a victory for David vs. Goliath. “Today’s ruling by the USITC sends a powerful message that even the world’s largest company is not above the law,” Joe Kiani, Masimo’s CEO, wrote on Thursday. “This important determination is a strong validation of our efforts to hold Apple accountable for unlawfully misappropriating our patented technology,” added Mr. Kiani.

In a statement to Reuters, Apple framed the move as putting lives at risk to boost Masimo’s product portfolio. “Masimo has wrongly attempted to use the ITC to keep a potentially lifesaving product from millions of U.S. consumers while making way for their own watch that copies Apple,” an Apple spokesperson said. “While today’s decision has no immediate impact on sales of Apple Watch, we believe it should be reversed, and will continue our efforts to appeal.”

Double Tap is arguably the killer feature in the new Apple Watch Series 9 and Apple Watch Ultra 2. The gesture is Apple’s answer to the problem of using a smartwatch when your opposite hand is holding a bag of groceries, dog leash, flashlight or anything else. In addition, it can be a splendid accessibility feature for people with disabilities that could limit arm or hand mobility. Although the company only offers limited customization of the feature at launch, you can tweak a couple of settings to fine-tune Double Tap to your liking.

Update to watchOS 10.1

Before you can use Double Tap, you’ll need to ensure your Apple Watch is up-to-date. It requires at least watchOS 10.1, which Apple rolled out to customers on October 25. First, you need to update your paired iPhone to at least iOS 17.1, which became available the same day. You can do that on your phone in Settings > General > Software Update.

After upgrading your phone’s firmware, open the Apple Watch app on your paired phone, and then go to General > Software Update. Tap “Install” and wait for the update to complete. Your watch must be charged to at least 50 percent while on its charger to initiate the installation.

How to customize Double Tap on your Apple Watch

Although Apple may offer more customization in future software updates, Double Tap currently only lets you change how it handles audio playback and the Smart Stack. The latter, new in watchOS 10, is the pile of widgets you view from your watch face by swiping up from the bottom of the screen or scrolling up with the Digital Crown.

First, open the Apple Watch app on your paired iPhone to customize these categories. Select Gestures > Double Tap, and then choose from the available options:

• Playback lets you choose between pinching your fingers to play / pause (the default) or skip to the next track while listening to music or podcasts.

• Smart Stack chooses how Double Taps navigates the pile of widgets. “Advance” means each tap moves to the next widgets (default), while “Select” will select the first widget with a subsequent tap.

Everything you can do with Double Tap on Apple Watch

After activating Double Tap, you can play around with all the things it can do. They include:

• Audio playback: Pause / resume or (after changing the setting above) skip to the next track.

• Phone calls: Answer or hang up a call.

• Notifications: Initiate the primary action from any alert. For example, reply to a message or snooze a reminder. (It works with third-party apps too.)

• Smart Stack: Scroll through widgets from any watch face.

• View messages: Read a full message when you receive a new text.

• Reply to messages: Reply with voice dictation when you get to the end of the message. Another Double Tap will confirm sending after you finish speaking.

• Read longer notifications: After opening an alert that doesn’t fit entirely on the screen, double-tap again to scroll through one that’s too long to display on your Apple Watch’s screen. You can repeat this until you’re at the end.

• Alarm: Snooze an alarm.

• Stopwatch: Stop or resume a stopwatch.

• Timers: When viewing a timer, pause (if it’s running), resume (if paused) or end the timer.

• Remote shutter: Take a photo on your iPhone when using the Apple Watch’s Camera Remote.

• Workout: Start or stop automatic Workout reminders if it detects that you’re exercising without having started a workout on your watch.

When you use Double Tap, a blue hand icon appears at the top of your watch’s screen. If you try double-tapping on something that isn’t compatible with the feature, the icon will appear and shake back and forth like it’s saying, “No.”

How to disable Double Tap on Apple Watch

If you navigate back to Settings > Gestures > Double Tap on your paired iPhone, you’ll see an option to disable the feature if you’re in a situation where you worry about triggering it accidentally. If you do that, you can always return to the same settings screen to re-enable Double Tap.

If you’re still on the fence about the Apple Watch models that support Double Tap, you can visit Engadget’s Apple Watch Series 9 review and our impressions of the Apple Watch Ultra 2.
