Bloomberg highlights all the big announcements expected to be made next week at Apple's October hardware event, such as an iPad Pro with a USB-C port instead of a Lightning port, a MacBook Air successor, and a new Mac Mini. From the report: The update to the iPad Pro will be the most significant in the product's history. The device was originally launched in 2015 in part as a counter-measure to Microsoft's Surface Pro, which gained a following with business users seeking large tablets with support for attachable keyboards and styluses. The iPad Pro models, which have larger screens, better cameras, and faster processors, are more expensive, which has sustained revenue growth. [Some of the new features, according to people familiar with the plans, include a nearly edge-to-edge display with slimmer bezels, a USB-C connector, Face ID, Animojis, a faster processor (variant of the A12 Bionic chip), a custom Apple graphics chip, and an updated Apple Pencil.]

For the Mac, Apple is planning its first wide-ranging upgrades since June 2017. The MacBook Air and Mac mini, a small desktop machine without a screen, have gone several years without notable changes. This, combined with interest in larger smartphones and competing PCs, led Apple to report the fewest Mac sales since 2010 in its fiscal third quarter. [Apple is reportedly planning a new entry-level laptop to replace the aging MacBook Air. It's expected to have a higher-resolution 13-inch screen, as well as slimmer bezels around the display. The Mac mini will have new processors and features for professional users. Apple's also working on refreshed iMacs, iMac Pros, and 12-inch MacBooks with faster processors, and at least some of these updates could be ready for the October launch.] The event's theme is "making," and it will take place in New York City on Tuesday at 10:00am EST.

An anonymous reader quotes a report from Motherboard: The Librarian of Congress and U.S. Copyright Office just proposed new rules that will give consumers and independent repair experts wide latitude to legally hack embedded software on their devices in order to repair or maintain them. This exemption to copyright law will apply to smartphones, tractors, cars, smart home appliances, and many other devices. The move is a landmark win for the "right to repair" movement; essentially, the federal government has ruled that consumers and repair professionals have the right to legally hack the firmware of "lawfully acquired" devices for the "maintenance" and "repair" of that device. Previously, it was legal to hack tractor firmware for the purposes of repair; it is now legal to hack many consumer electronics.

Specifically, it allows breaking digital rights management (DRM) and embedded software locks for "the maintenance of a device or system in order to make it work in accordance with its original specifications" or for "the repair of a device or system to a state of working in accordance with its original specifications." New copyright rules are released once every three years by the U.S. Copyright Office and are officially put into place by the Librarian of Congress. These are considered "exemptions" to section 1201 of U.S. copyright law, and makes DRM circumvention legal in certain specific cases. The new repair exemption is broad, applies to a wide variety of devices (an exemption in 2015 applied only to tractors and farm equipment, for example), and makes clear that the federal government believes you should be legally allowed to fix the things you own.

In addition to the foldable smartphone that's currently in the works, Samsung says it is also working on foldable laptop displays. "Like foldable smartphones, Samsung is collaborating with display makers to develop laptops with foldable displays that will not just simply fold in and out but create new value and user experience, amid the changing market trends for laptops," said Lee Min-cheol, vice president at marketing for PCs at Samsung, during a laptop event in South Korea earlier this week. The Verge reports: Foldable displays in laptops could transform the market for 2-in-1 devices. Existing convertible laptops attempt to flip and twist into tablet and media modes, but a foldable display would certainly help create new designs. Samsung hasn't revealed which companies it's working with, or any expected date for a prototype or retail device. Still, laptops like HP's new Spectre Folio would be an ideal candidate for a flexible and foldable display, or even potential devices like Microsoft's "pocketable" Surface.

YVRGeek shares a report: Earl Bakken, an electronics repairman who created the first wearable external pacemaker and co-founded one of the world's largest medical device companies, Medtronic, has died. He was 94. Bakken, who also commercialized the first implantable pacemaker in 1960, died Sunday at his home in Hawaii, Medtronic said in a statement. It didn't give a cause of death. Bakken and his brother-in-law, Palmer Hermundslie, formed Medtronic in 1949 and turned it from a struggling company they ran out of the Hermundlie family's Minneapolis garage into a multinational medical technology powerhouse.

An anonymous reader quotes a report from Ars Technica: Google's Pixel 3 smartphone is shipping out to the masses, and people hoping to take advantage of the new Qi wireless charging capabilities have run into a big surprise. For some unexplained reason, Google is locking out third-party Qi chargers from reaching the highest charging speeds on the Pixel 3. Third-party chargers are capped to a pokey 5W charging speed. If you want 10 watts of wireless charging, Google hopes you will invest in its outrageously priced Pixel Stand, which is $79.

Android Police reports that a reader purchased an Anker wireless charger for their Pixel 3, and, after noticing the slow charging speed, this person contacted the company. Anker confirmed that something screwy was going on with Google's charging support, saying "Pixel sets a limitation for third-party charging accessories and we are afraid that even our fast wireless charger can only provide 5W for these 2x devices." Normally we would chalk this up to some kind of bug, but apparently Google told Android Police that this was on purpose. The site doesn't have a direct quote, but it writes that, after reaching out to Google PR, it was "told that the Pixel 3 would charge at 10W on the Pixel Stand [and that] due to a 'secure handshake' being established that third-party chargers would indeed be limited to 5W." In an update, Google said the reason has to do with the "proprietary wireless charging technology" it has via its Pixel Stand and other select wireless chargers. The Pixel 3 only supports 5W Qi charging; "Google's 10W proprietary wireless charging technology" is what will allow the phone to charge at faster speeds.

"Google says it is 'certifying' chargers for the Pixel 3 via the 'Made for Google' program and pointed us to one such device, a Belkin charger called the 'Boost Up Wireless Charging Pad 10W for Pixel 3 and Pixel 3 XL,'" reports Ars Technica. "Belkin's description is very enlightening, saying 'Made with the Google Pixel 3 and Pixel 3 XL in mind, this wireless charging pad uses Google's 10W proprietary wireless charging technology. It's certified for Pixel, so you know that the BOOST UP Wireless Charging pad has been made specifically for your Pixel 3 and meets Google's high product standards.'"

An anonymous reader quotes a report from PC Magazine: Intel is denying a new report that claims the chipmaker is abandoning its 10 nanometer manufacturing process following years of delays. "Media reports published today that Intel is ending work on the 10nm process are untrue," the company tweeted on Monday. Hours prior to the tweet, semiconductor news site SemiAccurate claimed that Intel was pulling the plug on the chip-making technology over the company's ongoing struggles to bring it to full production. Chips built with the 10nm process were originally slated to arrive in 2016, but the company has repeatedly pushed that launch date back. During Intel's last earnings call, executives said they now expect 10nm chips to officially drop during the 2019 holiday season.

In response to SemiAccurate's report, Intel said it continues to make "good progress" on the 10nm technology. "Yields are improving consistent with the timeline we shared during our last earnings report," the chipmaker added in its tweet. The next-generation silicon will supposedly offer a 25 percent performance increase over 14nm-manufactured technology. The 10nm chips will also be able to run on 50 percent less power when clocked at the same performance of a 14nm processor. Intel will hold an earnings call on Thursday, so expect company executives to elaborate on 10nm's progress then.

An anonymous reader quotes a report from CNBC: Andy Jassy, the CEO of Amazon Web Services, followed Apple's lead in calling the for the retraction of Bloomberg's story about spy chips being embedded in servers. "They offered no proof, story kept changing, and showed no interest in our answers unless we could validate their theories," Jassy wrote in a tweet on Monday. "Reporters got played or took liberties. Bloomberg should retract."

Apple CEO Tim Cook told Buzzfeed on Friday that the scenario Bloomberg reported never happened and that the October story in Bloomberg Businessweek should be retracted. Bloomberg alleged data center hardware used by Apple and AWS, and provided by server company Super Micro, was under surveillance by the Chinese government, even though almost all the companies named in the report denied Bloomberg's claim. Bloomberg published a denial from AWS alongside its own report, and AWS refuted the report in a more strongly worded six-paragraph blog post entitled "Setting the Record Straight on Bloomberg Businessweek's Erroneous Article." Further reading is available via The Washington Post.

"Sources tell the Erik Wemple Blog that the New York Times, the Wall Street Journal and The Post have each sunk resources into confirming the story, only to come up empty-handed," the Washington Post reports. "(The Post did run a story summarizing Bloomberg's findings, along with various denials and official skepticism.) It behooves such outlets to dispatch entire teams to search for corroboration: If, indeed, it's true that China has embarked on this sort of attack, there will be a long tail of implications. No self-respecting news organization will want to be left out of those stories. 'Unlike software, hardware leaves behind a good trail of evidence. If somebody decides to go down that path, it means that they don't care about the consequences,' Stathakopoulos says.'"

An anonymous reader shares an excerpt from The Economist: Events about making new things are ten a penny. Less common are events about keeping things as good as new. Maintenance lacks the glamour of innovation. It is mostly noticed in its absence -- the tear in a shirt, the mould on a ceiling, the spluttering of an engine. Not long ago David Edgerton of Imperial College London, who also spoke at the festival, drove across the bridge in Genoa that collapsed in August, killing 43 people (pictured). 'We're encouraged to pride ourselves on all being innovators and entrepreneurs,' he said. Maintenance is often dismissed as mere drudgery. But in fact, as he pointed out, repairing things is often trickier than making them.

It is also more difficult for economists to measure. The discipline's most prominent statistic, GDP, is gross (as opposed to net) because it leaves out the cost of wear and tear. To calculate these costs, statisticians must estimate the lifespan of a country's assets and make assumptions about the way they deteriorate. [...] And how much do economies spend fighting decay? No one knows, partly because most maintenance is performed in-house, not purchased on the market. The best numbers are collected by Canada, where firms spent 3.3% of GDP on repairs in 2016, more than twice as much as the country spends on research and development. In closing, the report mentions the tyrannies of the ancient East where people were forced to maintain fragile irrigation systems. "In those societies, to repair was to repress," the report says. "But some people today have the opposite concern. They see maintenance and repair as a right they are in danger of losing to companies that hoard spare parts and information too jealously."

Essential Products, a startup founded in 2015 by Android creator Andy Rubin, was started to create a smartphone with high-end design features that wasn't associated with a particular operating-system maker. Unfortunately, reaching that goal has been harder than anticipated as the company has laid off about 30 percent of its staff. Fortune reports: Cuts were particularly deep in hardware and marketing. The company's website indicates it has about 120 employees. A company spokesperson didn't confirm the extent of layoffs, but said that the decision was difficult for the firm to make and, "We are confident that our sharpened product focus will help us deliver a truly game changing consumer product." The firm was Rubin's first startup after leaving Google in 2014, which had acquired his co-founded firm, Android, in 2005.

Essential's first phone came out in August 2017, a few weeks later than initially promised. It received mixed reviews, with most critics citing its lower quality and missing features relative to competing smartphones, such as a lack of waterproofing and poor resiliency to damage. The company dropped the price from an initial $699 within weeks to $499, and offered it on Black Monday in November 2017 for $399.

An anonymous reader quotes a report from Engadget: [N]ew research published in ACS Applied Energy Materials shows that it's possible to 3D-print lithium-ion batteries into whatever shape you need. The problem that has stood in the way of 3D-printed lithium-ion batteries (at least, until now) is that the polymers traditionally used in this kind of printing aren't ionic conductors. The goal was to find a way to print custom-sized lithium-ion batteries in a cost-effective way using a regular, widely available 3D printer. In order to make the batteries conductive, the team led by Christopher Reyes and Benjamin Wiley infused the polylactic acid (PLA) usually used in 3D printing with an electrolyte solution. The researchers also incorporated graphene and carbon nanotubes into the design of the case to help increase conductivity. After these design modifications, the team was able to 3D print an LED bracelet, complete with a custom-sized lithium-ion battery. The battery was only able to power the bracelet for about 60 seconds, but the researchers have ideas for how to improve the capacity. For those interested, Engadget has a short video on the subject.

A couple months ago, it was reported that the dearly departed mobile brand known as Palm would be making a comeback. That day has finally come. Yesterday, Palm announced The Palm, a credit card-sized Android smartphone that's supposed to act as a second phone. Droid Life reports: The Palm, which is its name, is a mini-phone with a 3.3-inch HD display that's about the size of a credit card, so it should fit nicely in your palm. It could be put on a chain or tossed in a small pocket or tucked just about anywhere, thanks to that small size. It's still a mostly fully-featured smartphone, though, with cameras and access to Android apps and your Verizon phone number and texts.

The idea here is that you have a normal phone with powerful processor and big screen that you use most of the time. But when you want to disconnect some, while not being fully disconnected, you could grab Palm instead of your other phone. It uses Verizon's NumberSync to bring your existing phone number with you, just like you would if you had an LTE smartwatch or other LTE equipped device. Some of the specs of this Verizon-exclusive phone include a Snapdragon 435 processor with 3GB RAM, 32GB storage, 12MP rear and 8MP front cameras, 800mAh battery, IP68 water and dust resistance, and Android 8.1. As Kellen notes, "It does cost $350, which is a lot for a faux phone..."

We've already seen a number of gadget fans perplexed by this device. Digital Trends goes as far as calling it "the stupidest product of the year."

The "real version" of Photoshop is coming to the iPad next year, complete with a user interface similar to the desktop application and all the main tools. Ars Technica reports: Photoshop for iPad has a user interface structured similarly to the desktop application. It is immediately familiar to users of the application but tuned for touch screens, with larger targets and adaptations for the tablet as well as gestures to streamline workflows. Both touch and pencil input are supported. The interface is somewhat simpler than the desktop version, and although the same Photoshop code is running under the hood to ensure there's no loss of fidelity, not every feature will be available in the mobile version. The first release will contain the main tools while Adobe plans to add more in the future. Cloud syncing is a key element of Photoshop on iPad. Edits made on the iPad will be synchronized transparently with the desktop -- no conversions or import/export process to go through. Using a feature not available in the iPad version should then be as simple as hitting save and then opening the file on the desktop, picking up where you left off. Adobe is also reportedly building a tablet painting app called Project Gemini, which "simulates real brushes, paints, and materials as well as the interactions between them," reports Ars. "It combines raster graphics, vector drawing, and the Photoshop engine into a single application designed for artwork and illustration."

The CEO of Samsung's mobile business, D.J. Koh, said you'll be able to use its upcoming foldable smartphone as a tablet that you can put in your pocket. While the phone has been teased and hyped up for several months, Koh stressed that it will not be a "gimmick product" that will "disappear after six to nine months after it's delivered." It'll reportedly be available globally. CNET reports: However, the foldable Samsung phone, like the Galaxy Round, will be Samsung's testbed device to see how reviewers and the market react. The Galaxy Round, which bowed vertically in the middle, was Samsung's first curve-screen phone. It's a direct ancestor to the dual curved screens we see on today's Galaxy S9 and Note 9 phones. The larger screen is important, Koh said. When Samsung first released the original Galaxy Note, he said, competitors called its device dead on arrival. Now, after generations of Notes phones, you see larger devices like the iPhone XS Max and the Pixel 3 XL, proving that consumers want bigger screens. A foldable phone would let screen sizes extend beyond 6.5 inches.

Slate's Rachel Withers argues that "tech companies that profit from Wikipedia's extensive database owe Wikimedia a much greater debt." Amazon's Alexa, for example, uses Wikipedia "without credit, contribution, or compensation." The Google Assistant also sources Wikipedia, but they credit the encyclopedia -- and other sites -- when it uses it as a resource. From the report: Amazon recently donated $1 million to the Wikimedia Endowment, a fund that keeps Wikipedia running, as "part of Amazon's and CEO Jeff Bezos' growing work in philanthropy," according to CNET. It's being framed as a "gift," one that -- as Amazon puts it -- recognizes their shared vision to "make it easier to share knowledge globally." Obviously, and as alluded to by CNET, $1 million is hardly a magnanimous donation from Amazon and Bezos, the former a trillion-dollar company and the latter a man with a net worth of more than $160 billion. But it's not just the fact that this donation is, in the scheme of things, paltry. It's that this "endowment" is dwarfed by what Amazon and its ilk get out of Wikipedia -- figuratively and literally. Wikipedia provides the intelligence behind many of Alexa's most useful skills, its answers to everything from "What is Wikipedia?" to "What is Slate?" (meta).

Amazon's know-it-all Alexa is renowned for its ability to answer questions, but Amazon didn't compile all that data itself; according to the Amazon developer forum, "Alexa gets her information from a variety of trusted sources such as IMDb, Accuweather, Yelp, Answers.com, Wikipedia and many others." Nor did it pay those who did: While Amazon customers pay at least $39.99 for an Echo device (and the pleasure of asking Alexa questions), Alexa freely pulls this information from the internet, leeching off the hard work performed by Wikipedia's devoted volunteers (and unlike high school students, it doesn't even bother to change a few words around). It's hardly noble for Amazon to support Wikipedia, considering how much Alexa uses its services, nor is it particularly selfless to fund the encyclopedia when it relies upon its peer-reviewed accuracy; ultimately, helping Wikipedia helps Amazon, too. [...] We all benefit from Wikipedia, but arguably no one more than the smart speakers, for which the internet's encyclopedia is a valuable and value-adding resource. It's frankly a little exploitative how little they give back. Withers goes on to note that Wikipedia seeks donations from its users -- it's a non-profit that runs entirely on donations from the general public. While one can argue that "Amazon is only packing up information that we ourselves leech for free all the time, [...] Alexa is also diverting people away from visitng Wikipedia pages, where they might noticed a little request for a donation, or from realizing they are using Wikipedia's resources at all," Withers writes.

A report from TechCrunch earlier this year pointed out that Amazon is the only one of the big tech players not found on Wikimedia's 2017-2018 corporate donor list -- one that includes Apple, Google, and even Amazon's Seattle-based sibling Microsoft, all of which matched employee donations to the tune of $50,000.

Last November, Razer unveiled a smartphone designed for gamers who value performance and power over bells and whistles like waterproofing and wireless charging. At an event Wednesday night, Razer took the wraps off its successor, aptly named Razer Phone 2, which sports a brighter, notch-less, 5.72-inch IGZO LCD display with a 2560x1440 resolution and HDR, wireless charging, IP67 water- and dust-resistance rating, and RGB lighting behind the Razer logo on the rear. Given the addition of waterproofing and wireless charging, the Razer Phone 2 appears to be much more well-rounded than its predecessor, making the decision all the more difficult when shopping for a premium, high-end smartphone. AnandTech reports: This display is rated at 645 nits peak, up to 50% higher than the previous Razer Phone, and also supports HDR. Razer states that the display also has wide color gamut, which turns out to be 98.4% of DCI-P3. Also on the front, it has two front facing speakers in identical positions to the previous generation, and it has a front facing camera and sensor (albeit with swapped positions). That front camera is an 8MP f/2.0 unit, capable of recording at 1080p60, a user-requested feature for streaming and selfie recording. The front of the device is Corning Gorilla Glass 5, an upgrade from GG3 in the last generation.

When we move to the rear, things change much more noticeably. Instead of the aluminum rear, Razer has a full Gorilla Glass 5 back, which helps enable Qi Wireless Charging, a much requested feature. This is alongside QuickCharge 4+ through a Type-C cable. On the rear we have the dual cameras, this time placed in the center just above the logo. This time around Razer has gone with a 20MP Sony IMX363 f/1.75 main camera with OIS, and an 8MP Sony IMX 351 f/2.6 telephoto camera to enable some extra zoom functionality. Below the cameras is the Razer logo, which has a full 16.8million color RGB LED underneath which users can adjust through the onboard Chroma software. The Razer Phone 2 is still very much power-focused, as it features Qualcomm's latest Snapdragon 845 CPU with a "vapor chamber cooling" which can allow the phone to draw 20-30% more power than other flagships. There's 8GB of LPDDR4X memory, 64GB of UFS storage with support for a microSD card, and a whopping 4,000mAh. Razer says their new smartphone will be priced at $799 and will start shipping in mid-November.

Google's human-sounding AI software that makes calls for you is coming to Pixel smartphones next month in select markets, like New York, Atlanta, Phoenix, and the San Francisco Bay Area. Google Duplex, as it is called, will be a feature of Google Assistant and, for now, will only be able to call restaurants without online booking systems, which are already supported by the assistant. Wired reports: A Google spokesperson told WIRED that the company now has a policy to always have the bot disclose its true nature when making calls. Duplex still retains the human-like voice and "ums," "ahs," and "umm-hmms" that struck some as spooky, though. Nick Fox, the executive who leads product and design for Google search and the company's assistant, says those interjections are necessary to make Duplex calls shorter and smoother. "The person on the other end shouldn't be thinking about how do I adjust my behavior, I should be able to do what I normally do and the system adapts to that," he says.

Fox, the Google exec leading the project, pitches Duplex as a win-win. Google users will be freed from having to make phone calls to plan their outings; restaurants without online booking systems will gain new customers. "Those businesses lose out because people say 'Unless I can book this online I'm not going to book,'" he says. Some people closer to the restaurant business worry that Duplex might make calling restaurants too easy for Google users. Gwyneth Borden, executive director of the Golden Gate Restaurant Association, a trade group for Bay Area restaurants, says people may use the technology to book multiple reservations and then flake out, or call restaurants over and over. Restaurants can opt out of receiving Duplex calls by speaking up during a call from Duplex, or through the website where businesses can manage listing information shown in Google's search and maps services. When calls go awry -- Fox says the "overwhelming majority" work out fine -- the software will alert an operator in a Google call center who takes over.

At its Pixel 3 launch event, Google announced a smart speaker called the Google Home Hub, featuring a 7-inch display to give you visual information, making it easier to control smart home devices and view photos and the weather. Interestingly, Google decided not to include a camera in this device for privacy reasons, as they want you to feel comfortable placing it in an intimate location, such as a bedroom. PhoneDog reports: Google explains that Home Hub will be able to recognize who is speaking to it using Voice Match to provide info for that specific person, which should help to make the device more useful in homes with multiple people. And when you're not using Home Hub, a feature called Live Albums will let you select certain people and have Google Photos create albums with images of these people. Another feature of Google's Home Hub is the Home View. With it, you can easily see and control your smart home devices. And then there's Ambient EQ, which uses a sensor that'll adjust the color and brightness of the Home Hub screen based on the ambient lighting. That includes dimming the screen at night when it's time for bed. Google Home Hub will be available for $149 in four colors -- Chalk, Charcoal, Aqua, and Sand. It will launch on October 22nd and each purchase will come with six months of YouTube Premium.

Microsoft has unveiled "Project xCloud," its new game streaming service designed to work across consoles, PCs, and mobile devices. "Scaling and building out Project xCloud is a multi-year journey for us," explains Microsoft's cloud gaming chief Kareem Choudhry in a blog post. "We'll begin public trials in 2019 so we can learn and scale with different volumes and locations." The Verge reports: Microsoft has built custom hardware for its datacenters, as The Verge previously exclusively reported, so that existing and future Xbox games will be compatible with the services. Games will be streamed to devices, and Microsoft has been testing the xCloud service with Xbox wireless controllers connected to consoles, mobile devices, and PCs. Microsoft says its research teams are "creating ways to combat latency" via advanced network techniques combined with video encoding and decoding. This should make game streaming viable on 4G networks, too.

After it was reported that proprietary diagnostic software was needed in order to replace key parts on computers equipped with Apple's T2 chip, iFixit decided to put that claim to the test by replacing a part on a brand-new 2018 MacBook Pro. They found that after pulling it apart and replacing the display, it still worked -- even without the software. Engadget reports: As they put it, any "secret repair kill switch hasn't been activated -- yet." So far, it has limited approaches that limit repairs based on security to the TouchID and FaceID sensors that require specialized software, as I noted yesterday, even though people have reported trouble with the ambient light sensor after replacing iPhone displays. While it's possible that a future software update could change things and make it require specialized software that only official Apple Stores and authorized service centers have access to, we're not there yet. Passing "right to repair" laws currently under consideration could be a big step to guaranteeing things stay that way.

The National Theater in London has introduced "smart caption glasses" that display dialogue on the lenses as actors speak (Warning: source may be paywalled; alternative source). The glasses should drastically improve the experience for audience members who have hearing difficulties. According to The New York Times, "The glasses can be used without charge for the play 'War Horse' and for the musical 'Hadestown,' and they will be available for all of the theater's 2019 season." From the report: Jonathan Suffolk, the theater's technical director, said that the glasses had taken two years to develop. "We could have offered the scripts on a phone, but we wanted a technology that was much more discreet and immersive and wouldn't disturb anyone," he said. The biggest challenge was creating software that allowed the words to be displayed in real time so that people wearing the glasses reached important moments -- such as jokes -- along with everyone else, Mr. Suffolk added. It is easy to load a script into a subtitling system and hit "ego" at the start of the play, he said, but problems would then arise if actors spoke quicker or slower than expected.

The software used by the theater follows live speech and recognizes certain stage directions, like lighting changes, to ensure the subtitles appear in the right place. The words are then transmitted to the glasses over Wi-Fi. According to Andrew Lambourne, a professor at Leeds Beckett University who worked on the project, a major obstacle that the software had to overcome was recognizing speech even when actors were talking over each other or being bombarded by sound effects. Mr. Suffolk said it was difficult to know how many people would use the equipment. The theater has bought 50 pairs, at a cost of around $1,050 per pair. The National Theater will make the glasses available to some other British venues next year, including during a touring production of "Macbeth." The Barbican Theater in London said in a statement that it was in talks about using them.
