Instagram now lets you video chat with up to three buddies

Instagram

It’s a busy time for Instagram just now. Right after launching IGTV, it’s now introduced video chat in Instagram Direct that lets you chinwag with a single buddy or several at once.

“Video chat gives you the experience of real-time video in a private space and helps you feel close and connected to friends when you can’t be together,” the Facebook-owned company said in a post on Tuesday.

The feature lets you connect with all of your Instagram friends whether they’re using an iOS or Android device, and unlike some chat and messaging services, you don’t need a phone number to get started. So long as you have an active Direct thread with them, you’re good to go.

To begin a video chat, swipe into your Direct inbox and open any message thread. See the camera icon in the top right corner? Tap it to initiate a call.

During a chat, you can minimize the video and do other stuff on the Instagram app like sending messages and photos in Direct, checking your feed, posting a story, and so on.

The new feature lets you chat with as many as four buddies at a time, with each participant given their own space on the display so you can all see each other.

“If there’s an active video chat in a group thread, the camera icon will turn blue,” Instagram says. “Simply tap the camera to join in the fun.”

If you want to leave an active chat among friends or end the call if it’s with one other person, then tap the red phone icon at the bottom of the display.

Don’t want to receive a chat request from someone? Just block them to prevent calls. It’s also possible to mute an individual if you’d prefer not to receive notifications from them. To confirm your video chat notification settings, tap the gear icon on your profile and you’ll find the new video chat control in Push Notifications.

Explore and camera effects

Instagram has also given some attention to the Explore tab, retaining its style but adding new topic channels along the top to help you surface content of interest. You can move quickly between the different topics by swiping the entire grid.

Finally, Instagram’s one billion users can also have fun with some new camera effects designed by Ariana Grande, BuzzFeed, Liza Koshy, Baby Ariel, and the NBA.

Introducing video chat takes Instagram another step away from its roots as a simple photo-sharing app, but with people now so used to having social media apps packed with features, the team behind it calculates that this latest one will prove a hit. It should certainly achieve its main aim of keeping users within the app for longer, eliminating the need to hop out to a competitor to initiate a call. Launching with a group video option is also important, as the likes of Facebook Messenger, WhatsApp, and Snapchat already offer such a feature. Apple’s FaceTime will begin offering group video chats with iOS 12 when it launches in the fall.

Amazon is finally bringing Alexa voice control to the iPhone

Amazon Alexa may be largely considered to be one of the best digital assistants out there, but users haven’t been able to interact with Alexa using their voice on their iPhone. Thankfully, that is now changing — Amazon is finally allowing iOS users to control Alexa with their voice.

The move to Android and iOS marks a big push for Amazon into third-party operating systems. Android users have had voice control since the beginning of the year, and at the time Amazon promised that the feature would be coming to iOS “soon.” Of course, you won’t be able to use Alexa natively on iOS — Apple simply doesn’t allow third-party digital assistants to get the same treatment as Siri — but you will be able to simply open up the Alexa app to ask Alexa questions. The update will be rolled out over the next few days, so if you don’t have it just yet, you will soon.

Like Alexa in your Amazon Echo, Alexa on your phone can do all kinds of things. For starters, you can use it to control your connected smart home devices. On top of that, you can ask it about things like the weather and access any of its 40,000-plus skills. Alexa on iOS and Android also has a visual component to it — if you ask about the weather, you get a visual representation of the answer on your phone. If you ask about your calendar events, you see your upcoming appointments.

It makes sense that Amazon would launch the feature on Android and iOS. Because of the fact that the company doesn’t have a decently large mobile user base of its own, it faces an uphill battle against the likes of Apple and Google, who have large user bases that have Google Assistant and Siri available to them in their pocket. Because of that, launching Alexa on mobile seems like the best way for Amazon to proceed in its digital assistant endeavors.

Alexa has been getting increasingly popular over the past few years. Mobile aside, the digital assistant is available in a range of speakers, plus it’s now coming to cars and kitchen appliances too.

Editors’ Recommendations

• LG’s SmartThinQ appliances cook up support for both Alexa and Google Assistant
• Alexa will automatically boot up personal app preferences based on your voice
• You can now set Amazon Alexa as the default home assistant on your Android
• You can now unlock your Yale smart lock with your voice via Alexa

Razer Blade 15 vs. MacBook Pro

Riley Young/Digital Trends

Apple and Razer typically offer rather different products to one another and as such, typically have rather different user bases too. However, as Razer has trimmed and tightened its laptops into sleek gaming machines, today both companies offer low weight, great looking laptops of various sizes.

That means new buyers may find it increasingly tough to pick which path to go down, which is why we’re pitting the Razer Blade 15 vs. MacBook Pro, to see which would be the better choice.

Design

There’s a reason we call Razer the “Apple of gaming” in our recent review of the Blade 15 — because typically its hardware looks like black-painted MacBooks. That’s changed up in the latest design though, with the Razer Blade 15 having a more boxy look while maintaining the sleek lines and low-profile form-factor of its predecessors. Its bezels have been trimmed down for this generation of hardware too, making for a seamless-looking display. Razer did have the forethought to retain a larger top bezel though, which means the webcam remains mounted up top where it belongs.

The MacBook Pro is as always, a beautiful design and its silver paint job does make it look starkly different to Razer’s usual black aesthetic. It’s also thinner and lighter than the Razer Blade 15. It doesn’t offer quite so much versatility in port selection though. While some MacBook Pro versions can have up to four USB ports, they are all Type-C, whereas the Blade 15 has a single USB-C Thunderbolt 3 port and three USB-A 3.1 ports. It also has an HDMI and Mini DisplayPort for hooking up external displays.

Keyboards are also noticeably different between the two. We found the latest generation of MacBook Pro frustrating in its keyboard design (which has a tendency to fail). While better than its predecessors, the low-profile “butterfly” switches are not something we were enamored with. The Razer Blade 15, on the other hand, has a fantastic keyboard, though Razer did make one arbitrary change its layout which took some getting used to.

The MacBook Pro does have the Touch Bar as an alternative input, but we found that rather gimmicky with no real purpose.

Performance

Riley Young/Digital Trends

Considering one of the laptops in this head to head is designed for gaming and the other isn’t, it’s no surprise to learn that the Razer Blade 15 is the more powerful machine — even if the Pro is the best MacBook available. The entry-level model starts at $1,900 and packs an eighth-generation Intel Core i7-8750H CPU with 16GB of RAM under the hood. It also has an Nvidia GTX 1060 Max-Q graphics card for gaming on its 1080p IPS monitor. For those with deeper pockets, there are options for up to a GTX 1070 graphics card, a 144Hz 1080p display, and a 4K option, though prices close in on $3,000 at the top end. There’s also always the option of expanding its graphical capabilities with an external GPU using Razer’s Core V2 external graphics enclosure.

The MacBook Pro, on the other hand, starts at $2,000 with a seventh-generation Intel Core i7 CPU, 16GB of RAM, and no dedicated graphics at all. Optional upgrades let users opt for a higher CPU clock speed and Radeon Pro graphics, but that won’t hold a candle to the Razer Blade’s offerings. One advantage the MacBook does have though is in its default display. All Pro versions have a 2,880 x 1,800 display, which looks beautiful. It doesn’t support high-refresh rates, but that’s of less benefit on a non-gaming system anyhow.

The MacBook offers better storage options for potential buyers too. Where the Blade 15 can only offer up to 512GB of PCIe storage, the MacBook Pro can come with up to 2TB of solid state space.

Portability

One of the classic problems with gaming laptops is that they aren’t the most portable. Razer’s Blade 15 is its best effort yet but it still comes in heavier than the MacBook Pro. The Blade 15 is 13.98 x 9.25 x 0.66-inches and weighs in at 4.56 pounds, while the MacBook Pro is 13.75 x 9.48 x 0.61-inches and 4.02 pounds. The difference there isn’t huge and you’re unlikely to notice day to day, especially since you have to accept slightly weightier hardware at the 15-inch form factor.

The Razer Blade has the larger battery by the numbers at 80-watt hours, but its heftier hardware does mean it’s not quite as efficient a machine as the Apple alternative. It managed just over seven-hours in our video loop tests and just under four and a half hours in our web-browsing test. Apple claims around 10 hours of general usage for its 15-inch MacBook Pro, which was something that played out in our review of the 13-inch version. Much like the weight and size, what you get with the Razer is impressive considering its internal hardware, but it’s fair to say that the MacBook Pro is still a little bit more portable.

Bang for buck

Riley Young/Digital Trends

When it comes down to it, the Razer Blade 15 offers a lot more for your money than the MacBook Pro. While the Apple laptop is a beautifully designed piece of kit, with a gorgeous display, decent battery life, and a slightly lighter frame, the Blade 15 is just so much more capable. Its battery life and weight are close enough to not be major factors, it looks stunning, and has a better keyboard. But on top of all those close-run races, it destroys the MacBook Pro in terms of performance at a competitive. Its processor is a six-core powerhouse that steams ahead of the Apple’s older hardware offerings and the on board graphics card has real gaming power, unlike the MacBook’s Radeon GPU.

While some may opt for the MacBook Pro because of a passionate interest in Apple’s MacOS platform, there is little reason to otherwise. The Blade 15 is an all round better piece of kit.

Qualcomm’s new Snapdragon 632, 439 and 429 are coming to mid-range phones this year

These are the new chips you’ll see in mid-range phones for the next two years.

Qualcomm’s Snapdragon 800-series platforms get most of the headlines, but it’s the mid-range 600 and 400-series that power more devices and are critical to the performance of less expensive phones. With that in mind, Qualcomm has announced the new Snapdragon 632, 439 and 429 — upgrades from the current 626, 430 and 425, respectively.

Further pushing the envelope in the mid-range, the Snapdragon 632 brings some nice features. The base architecture is 8 Kryo 250 CPU cores, split into 4 performance cores and 4 efficiency-focused cores each at 1.8GHz. There’s a new Adreno 506 GPU, support for FHD+ displays and support for up to dual 13MP cameras or a single 24MP camera with real-time portrait mode processing and wide-angle lenses. The new 632 is likely to power phones up to the $400 MSRP range — and if the current devices using the 626 are any indication, this will be a great chip for getting enough power while having great battery efficiency.

You’ll see these chips in thousands of phone models over the next two years.

On the lower end, things aren’t as exciting. The Snapdragon 439 is an octa-core chip with Cortex A53 cores arranged in a set of 4 at 1.95GHz for performance and another 4 at 1.45GHz for efficiency. The 429 is a basic quad-core unit, with just the performance set of 1.95GHz cores. The 439 supports FHD+ displays and 12MP single or 8+8MP dual cameras, while the 429 maxes out at HD+ and 16MP or 8+8MP cameras. You’ll find the 439 and 429 in thousands of varieties of mid-range phones over the next couple years, from the $300 range all the way down toward $100 MSRP.

Outside of those differences, there are some consistencies. All of the new chips use the same supporting chips for functions like RF and audio, all support dual SIM with dual VoLTE connections, and each has some level of native artificial intelligence processing built in. A sneaky important announcement is that all three chips are using FinFET 3D transistor technology, which is used in high-end chips and lets them be more powerful while also using less power. So even though the 600 and 400-series are still not high-end chips, they’re sharing some core technology with the 700 and 800 series.

These aren’t high-end chips, but they share some core technology with Qualcomm’s best.

A notable talking point from Qualcomm is the cross-compatibility with these new chips and existing ones. The 632 is pin compatible with the existing 626, 625 and 450 chips, and the 439 and 429 are pin compatible between each other — that all means that manufacturers can pick and choose which one they want without making further architectural changes on their boards, and in the case of the 632 they could more easily choose to move from an older chip to the newer one in the middle of a development cycle.

Qualcomm’s partners are expected to release phones with the new platforms in the second half of 2018, so we won’t have to wait long to see what these processors can do in the real world.

Qualcomm wants to own the ‘kid watch’ market with its new Snapdragon Wear 2500 platform

More versions of Android optimized for the wrist.

The Android smartwatch space may be sputtering along, but Qualcomm is not worried. Its new Snapdragon Wear 2500 platform, a pseudo-successor to the Snapdragon Wear 2100, is aimed at children. Specifically, kids aged four to 10 years old.

Such an age bracket may seem a bit young to be outfitted with connected gadgets — most kids under 10 don’t yet have a smartphone — but Qualcomm thinks the realities are related. Parents want their kids to be accessible and trackable without giving them phones, and the Snapdragon Wear 2500 platform ostensibly provides the tools for manufacturers like Huawei, a hardware launch partner, to build those experiences.

An example of a kid watch from Vtech. Qualcomm thinks it can improve on this already-perfect design 😂

The Snapdragon Wear 2500 platform builds on the Snapdragon Wear 2100, which was itself based on the aging Snapdragon 400 smartphone chip from 2013, by integrating a number of Cortex-A7 cores, a built-in LTE modem for phone calls, always-listening voice activation for Google Assistant, a sensor hub for gestures and activity tracking, NFC for payments at school, GPS and geofencing for location, and even a 5MP camera for video calls.

Qualcomm says that these watches won’t run Wear OS but a variant of Android Oreo optimized for small screens and just 512MB of RAM.

One area Qualcomm says it’s improved dramatically over the Snapdragon Wear 2100 is the battery: by utilizing improvements in design, power efficiency in various chips, and a lower-power modem, Qualcomm believes Snapdragon Wear 2500-powered watches will get over a day of use despite doing much more than the average smartwatch.

In reality, though, what it sounds like Qualcomm is doing is providing the tools for hardware companies to build small, basic wrist-worn smartphones for kids. Huawei thinks this could offset the lull in smartwatch interest, but it remains to be seen whether there’s a sizeable audience for these kinds of experiences, especially since plain Android on a watch has typically been awful.

Qualcomm will be shipping development kits to interested parties in the fall of 2018, so it’s unlikely we’ll see any commercial products based on the Snapdragon Wear 2500 platform until 2019. In the meantime, we’re still waiting for Qualcomm’s real update to its smartwatch platform — the one that’s set to power the next-generation of adult smartwatches. That is, if anyone’s still buying.

Why leaky taps make that ‘plink’ noise — and what we can do about it

Whether it’s curing epidemics, figuring out how to knock Earth-bound asteroids off course, or working out the rocket science that will let us colonize Mars, there are some problems we’re glad to know the world’s best and brightest are focused on solving. A possible fourth? Giving us insight into out why in the name of all that is good do leaky taps drip so darn loudly — and what we can do about it.

This last conundrum was the focus of a recent research project from investigators at the U.K.’s University of Cambridge. While water droplets have been a source of scientific interest for more than a century, this is the first time anyone has tried to figure out the physical explanation behind the highly distinctive sound.

“This study was all about finding out what was behind the well known ‘plink’ sound produced by a drop of water falling into some more water — for example, from a leaking roof into a bucket, or a tap into a sink,” researcher Sam Phillips, who carried out the work for his masters’ degree dissertation, told Digital Trends.

The team used ultra high-speed cameras and sensitive microphones, placed above and below the water surface. With this setup, they then took slow-motion videos of water droplets impacting the water surface and synchronized these images with the sound recording. Their research demonstrated that the sound is, in fact, driven not by the splash that we see, but by a tiny vibrating air bubble which gets trapped under the surface of the water.

“We also found that the way this bubble produces the sound is that its vibrations cause the water surface itself to oscillate, with the surface then acting like a piston to drive sound waves into the air,” Phillips continued.

So how do we stop these sounds, so that we will never again have another night’s sleep disrupted by an unreasonably loud leaky tap?

“As part of confirming that the trapped air bubble really was causing all the sound we tried to prevent it from being produced,” Phillips said. “One way we did this was by adding a small amount of washing up liquid, or detergent, to the water surface to change the surface tension and prevent the bubble from being trapped under the water. In our experiment this worked, so it may be that adding a small amount of washing up liquid to the water that is being dripped into is a simple solution to stop the sound.”

A paper describing the work was recently published in the journal Scientific Reports.

Google showed off a new version of Google Maps, with features like personalized restaurant recommendations, at Google I/O 2018 in early May. Now, it looks like that new version of Google Maps is finally rolling out.

The changes could help make Google Maps a whole lot more useful than it already is. The overall interface is relatively similar to the old Google Maps, but you’ll now find two new tabs at the bottom of the screen — “Explore,” and “For You.”

As the name suggests, the “Explore” tab will show you things like recommended restaurants and cafes nearby, events coming up in the area, and more. It’s also a nice way to show a list of particular types of restaurants. After launching the new version of Maps, we found an “Outdoor dining” list, “Vegan restaurants” list, and even an “Outdoor drinking” list. You can also filter results to only show restaurants, only show places you can get coffee, and so on. It also keeps track of places you’ve visited on any trending lists.

The “For you” tab is similar in that it provides recommendations for restaurants, but it also shows newly opened venues nearby, allowing you to “Follow” certain areas that you might be interested in. It’s a nice way for new businesses to get the word out while allowing users to discover something new. The tab is a little bare for now, but Google says it will be bringing more content in upcoming weeks.

Another new feature leverages your location history to tell you how likely Google thinks you are to enjoy a restaurant. The feature, called “Your Match,” essentially shows a percentage match compared to places you visited before. You can also tell Google Maps exactly what you’re interested in by heading to Settings, selecting “Exploring Places,” and then tapping on “Food & drink preferences.”

Some of the new features should be rolling out globally, but the “For you” tab is currently only available in the United States, United Kingdom, Canada, Australia, and Japan. The new version of the app is available now, though Google often rolls new apps out in stages, so if you don’t have it yet you may just have to sit tight for a few days.

Spit-checking mouthguard can tell if athletes are tired or mentally drained

NextFlex

Xerox Parc, the legendary research and development center, is probably best known to readers as the research lab that Steve Jobs visited in the late 1970s, getting his first glimpse at the graphical user interface concept he later made famous with the Mac. But Parc has been involved in plenty of other innovative research projects over the years — and its latest is no different. Working with flexible hybrid electronics group NextFlex and the University of California, San Diego, Xerox’s Parc development lab has created a smart mouthguard biosensor which can detect early signs of dehydration, exhaustion, and mental engagement levels, based on nothing more than a sample of your saliva.

The sensor is made from electronic plastic foil and is designed to fit into an ordinary mouthguard for use in everything from workouts to military missions. It does this by analyzing the lactate and glucose naturally found in saliva and is able to send this information to a connected smartphone in close to real time.

“The electrochemical sensor system is fabricated on a small, flexible plastic foil that is mounted on a mouthguard,” David Schwartz, Parc’s manager of Energy Devices and Systems, told Digital Trends. “Sensing is through chronoamperometry, an established electrochemical measurement technique, based on enzymatic oxidation of target species. Chronoamperometry is known to have high sensitivity, specificity, and capability for quantification of analyte concentrations.”

The printed sensor electrodes in the mouthguard are replaceable and interchangeable with electrodes sensitive to other analytes including glucose, uric acid, and more. The electronics are protected from the saliva by an encapsulant, and the batteries are wirelessly rechargeable, which allows the battery electrodes to be completely enclosed.

“The background on the project is that there was some proof-of-concept work already completed with rigid circuit boards, and the question to be answered was, ‘How could you create a form factor that someone would fit comfortably into a person’s mouth so that they would actually wear it?’” Jason Marsh, NextFlex’s director of technology, told us. “Parc developed the sensor and conducted small-scale integration on a prototype. NextFlex’s capability is to take the prototype and scale it to be manufacturable in higher volumes.”

With a proof of concept demonstrated, both parties are now keen to commercialize the technology. The next step of this will likely involve fabricating multiple units for in-mouth testing.

Along with the concussion-diagnosing mouthguard we wrote about earlier, it seems that this is the decade when this otherwise innocuous piece of sports equipment gets smart.

Future pain-free microneedles could be inspired by mosquitos

If you receive a painless injection courtesy of a new microneedle in the near future, you may owe a debt of gratitude to the mosquito. The reason? Because quite possibly everyone’s least favorite insect is the inspiration behind new work being carried out by researchers at Ohio State University.

“The reason we look at nature for cues is because nature has been through so much evolution to discover the simplest and most efficient methods,” Bharat Bhushan, a professor of Mechanical Engineering at Ohio State, told Digital Trends. “In this work what interested us was the way that mosquitoes bite, since they are able to do this for several minutes without us feeling a thing. We wanted to use this to see if we could develop a painless microneedle.”

So far, they haven’t actually developed a prototype of this needle. What they have done is to take a much closer look at the unique components that enable the mosquito to bite people without causing them discomfort. The mosquito uses a combination of four things. These include the use of a saliva-based numbing agent during biting, a serrated design for the “needle,” vibration during the piercing process, and a combination of soft and hard parts on the proboscis, the insect’s elongated sucking mouthpart. This combination allows the mosquito to pierce the skin with just one-third of the force required for an artificial needle, while the numbing agent takes care of the rest.

Based on the team’s research, Bhushan suggests that it would be possible to create a microneedle containing two needles. One of these would inject a numbing agent, while the second could be used for drawing blood or injecting a drug. This second needle would also bost a serrated edge like the mosquito’s fascicle, be flexible and softer on the tip and sides, and vibrate when inserted. He claims that the materials and technology to create such a needle already exists.

While this could prove to be more expensive than traditional needles, it may be useful for cases in which children or adults have a phobia around the use of needles. “It could also be in cases of drug delivery in patients, where the needle needs to be in for a long period of time,” Bhushan continued.

This isn’t the only pain-free needle project we’ve covered at Digital Trends. Researchers at the Massachusetts Institute of Technology are busy developing a new smart injection technology that promises a way to inject drugs without the needles by blasting them into your body at Mach 0.7. Still, we could do a lot worse than having competing projects designed to bring us pain-free injections, right?
