Following its release of a pocket-sized handheld camera late last year, DJI – the Shenzhen-based tech company best known for its drones – has recently launched its first action camera, the Osmo Action. While the new camera is a latecomer to the game, it should compete well with similar products, such as the GoPro.

Design and Hardware.The Osmo Action doesn’t stray too far from conventional action camera design – it is small, rectangular-shaped and made of rugged composite material that combines plastic and rubber.
It is waterproof, shockproof and, at 124g, can be easily mounted on top of helmets, skateboards or bicycle handlebars.

There’s a 12-megapixel fisheye lens with a wide 145-degree field of vision. All of this is standard fare for action cameras and is neither better nor worse than GoPro’s Hero 7 Black in any meaningful way.

There is, however, one stand-out feature: in addition to the main screen on the backside of the camera, there is a secondary front-facing display, which has never been offered before on an action camera.

Having a front-facing screen improves shooting selfie videos significantly as it allows the user to see precisely what they’re recording. It makes so much sense in today’s selfie-centric vlogger generation that, in hindsight, it’s baffling why GoPro has never thought of this before.

The camera has three hardware buttons – power, shutter, and mode switch – and a responsive main screen that supports swiping and tapping. The bright, 2.3-inch main screen is large enough to let the user easily tweak shooting modes and settings.

The camera runs on a relatively small 1,300mAh battery, which offers about 90 minutes of recording time, but it is removable, and thus, interchangeable. The footage is stored on a micro-SD card, which is not included with the camera.

Software.The Osmo Action can connect to DJI’s Mimo app, available on both iOS and Android, and once linked; the camera can be controlled remotely with a mobile device. However, the device’s touch screen interface is so intuitive that most reviewers found little need to sync up the app.

The camera can capture videos at a wide range of resolutions, from 720p up to 4K/60fps. Shooting in lower resolution, such as 1080p, allows the camera to bump the framerate up to 240fps, ideal for capturing fast-moving moments.

Performance.Electronic image stabilization (EIS) is crucial for action cameras as they’re meant to shoot on the move, so it’s just as well DJI has years of experience writing EIS algorithms for its high-flying drone cameras.

The camera’s EIS mode is called “Rock Steady,” and it can be activated with a couple of taps. The reason DJI gives the option to toggle EIS on or off is that there are trade-offs.

Footage with “Rock Steady” on have a slightly smaller field of vision (digital cropping is essential for EIS) and dynamic range suffers due to lack of HDR (high dynamic range). You should turn the mode off to get the best video quality and colors if you’re shooting with the device in a stationary position, but anytime you’re moving, turn it on as the difference in fluidity and stability is drastic.

Conclusion.
At $380, the Osmo Action initially seemed expensive for someone who might not participate in extreme sports and who has tested fully capable smartphones for around that same price range.
​
Extreme sport participants who like to document their adventures used to have their options dominated by GoPros. At $349, DJI’s Osmo Action is offering a cheaper alternative to the GoPro’s Hero 7 Black at $420, and you get the front-facing second screen. Not surprisingly, GoPro has now reduced the price of the Hero 7 to $349! The Osmo Action may have just taken GoPro’s throne.

Cars will soon be able to recognize you by your eyes, skin, gait and even your heartbeat, enabling a host of personalized experiences but raising troubling privacy questions, as well.

Why it Matters. New biometric technologies being developed by automakers will authenticate your identity and help keep you safe by also monitoring your health and wellbeing. But unless carefully guarded, that personal data can also be easily exploited by cybercriminals.

What's Happening. Automakers and their suppliers are working on a variety of driver-identification technologies such as facial and iris scans, as well as voice and fingerprint tracking.

• They would enable a driver to start the engine without a key and the car would automatically adjust the seats, mirrors, climate and audio settings.
• The car could then also communicate with home automation systems, turning on lights or opening the garage, for example, and automatically pay for tolls, parking or gas.
• For autonomous vehicles and car-sharing apps, ID verification is important to ensure passengers get into the right vehicle and are who they say they are.

What's Next. Such ID features are coming in the next year or so, followed by a second wave of more advanced biometric technologies. Goode Intelligence says the market for automotive-related biometric content may reach nearly $1 billion by 2023.

• An alcohol detection system that could be available as early as next year would know whether a motorist is drunk by gathering a whiff of their ambient breath. The system is being developed by a public-private partnership.

• B-Secur is marketing its Heartkey technology that can identify a driver by the unique rhythm of their heartbeat, and measure their level of stress or fatigue or even detect early signs of a stroke or heart attack, CEO Alan Foreman tells Axios.

• Aerendir Mobile's sensors capture micro-vibrations – tiny muscle twitches from cells in the human nervous system – to identify individuals and monitor their well-being by creating a neurological signature that's akin to a million-character-long password, founder Martin Zizi tells Axios.

Yes, But. Just as facial recognition systems are sounding alarms about privacy and human rights, biometric technologies in vehicles raise privacy concerns, experts say.

• Biometric information can be particularly revealing and immutable, Lauren Smith, senior counsel for the Future of Privacy Forum, says. Unlike a password or account number, you can't change your biological makeup.
• Without federal laws on bioprivacy, carmakers need to abide by state data-protection laws, many of which require notice before biometric data is collected, and the ability to opt out.

• Carmakers that signed the Automotive Privacy Principles created a higher, opt-in threshold for biometric information, requiring consent before data can be used for marketing or shared with others.

If you’re lucky enough to get to travel abroad, you know it’s getting easier and easier to use our phones and other gadgets to translate for us. So why not do so in a way that makes sense to you? This little gadget seeking funds on Kickstarter looks right up my alley, offering quick transcription and recording – plus music playback, like an iPod Shuffle with superpowers.

The ONE Miniis not that complex of a device – a couple of microphones and a wireless board in tasteful packaging – but that combination allows for a lot of useful stuff to happen both offline and with its companion app.

You activate the device, and it starts recording and both translating and transcribing the audio via a cloud service as it goes (or later, if you choose). That right there is already super useful when you have meetings to transcribe, or you’re meeting one-on-one with someone who doesn’t speak English.

Recordings are kept on the phone because there is no memory onboard the device. There’s an option for a cloud service, but that probably won’t be necessary, considering the compact size of these audio files. If you’re paranoid about security, this probably isn’t your solution, but for everyday stuff, it should be just fine.

If you want to translate a conversation with someone whose language you don’t speak, you pick two of the 12 built-in languages in the app and then either pass the gadget back and forth or let it sit between you while you talk. The transcript will show on the phone, and the ONE Mini can speak the translation in its little robotic voice.

Right now, translation is only available online, but the company plans to offer offline translation for specific language pairs that have reliable two-way edge models, probably Mandarin-English and Korean-Japanese.
It has a headphone jack, too, which lets it act as a wireless playback device for the recordings or your music, or to take calls using the nice onboard mics. It’s lightweight and has a little clip, so it’s probably better than connecting directly to your phone in many cases.
​
There’s also a 24/7 interpreter line that charges two bucks a minute. Though most people won’t use the service, in an emergency, it could be pretty helpful to have a panic button that sends you directly to a person who speaks both the languages you’ve selected.
Right now you can buy a ONE Mini for $79. They’ve already passed their funding goal and are planning on shipping in June, so it shouldn’t be a long wait.

Flying cars do sound cool, but whether they’re a good idea is up for debate. Fortunately, they do seem to have some benefits, among them, improved efficiency – at least on long trips.

Air travel takes an enormous amount of energy since you have to lift something heavy into the air and keep it there for a good while. This is often faster but rarely more efficient than ground transportation, which lets gravity do the hard work.

Of course, once an aircraft gets up to altitude, it cruises at high speed with little friction to contend with, and whether you’re going 100 feet or 50 miles, you only have to take off once. So, University of Michigan researchers thought there might be a sweet spot where taking a flying car might actually save energy. It turns out there is – kind of. The team published their resultsrecently in Nature Communications.

The U of M engineers made an efficiency model for both ground transport and electric vertical take-off and landing (VTOL) aircraft, based on specs from aerospace companies working on them.

“Our model represents general trends in the VTOL space and uses parameters from multiple studies and aircraft designs to specify weight, lift-to-drag ratio, and battery-specific energy,” said study co-author Noah Furbush in a U-M news release.

They looked at how these various theoretical vehicles performed when taking multiple numbers of people different distances, comparing energy consumed.

As you might imagine, flying isn’t efficient for going a mile or two, since you use up all that energy getting to altitude and then have to come right back down. But at the 100-kilometer mark (about 62 miles) things look a little different.

For a 100 km trip, a single passenger in a flying car uses 35% less energy than a gas-powered vehicle, but still 28% more than an electric vehicle. The flying car is better than the gas one starting at around 40 km. But it never really catches up with the EVs for efficiency, though it gets close. 

To make it better, they had to adjust the numbers a bit, assuming that flying taxis would be more likely to operate at full capacity, with a pilot and three passengers, while ground vehicles were unlikely to have their average occupancy of 1.5 people change much. With that in mind, they found that a 100 km trip with three passengers barely beats the per-person efficiency of EVs.

That may seem like a bit of a thin victory, but keep in mind that the flying car would be making the trip in a quarter of the time, unaffected by traffic and other issues. Plus there’s the view.
​
It’s all theoretical right now, naturally, but studies like this one help companies looking to get into this business decide how their service will be organized and marketed. I think we’ll see these alternative forms of travel and sooner than many planners thought.

Travelers might finally be getting a break from the ever-frustrating airport security rules. Thanks to the introduction of new carry-on baggage scanners called CT (Computed Tomography), travelers won’t have to take electronics or liquids out of their bags. The TSA announced the rollout of this new technology, which would ultimately cut down on long security lines and make the airport experience much smoother.

The new machines can create 3D images of a bag’s contents and automatically detect and scan items you are currently required to remove. This includes electronic devices like laptops and even liquids. According to Bloomberg Government, 300 of these new machines have been ordered by the TSA so far, and they will begin to appear in airports this summer. Eventually, the goal is to replace all current X-ray machines with these new CT scanners. The TSA has been testing these machines since 2017, and once airport employees become comfortable operating the new equipment, shorter security lines are expected.
​               
The list of airports that will receive the new CT machines has not yet been released, though they are currently being used at the following airports:

• Hartsfield-Jackson Atlanta International Airport (ATL)
• Baltimore-Washington International Airport (BWI)
• Chicago O’Hare International Airport (ORD)
• Cincinnati/Northern Kentucky International Airport (CVG)
• Detroit Metropolitan Wayne County Airport (DTW)
• Houston Hobby Airport (HOU)
• Indianapolis International Airport (IND)
• John F. Kennedy International Airport (JFK)
• Logan International Airport (BOS)
• Los Angeles International Airport (LAX)
• Oakland International Airport (OAK)
• Phoenix Sky Harbor International Airport (PHX)
• St. Louis Lambert International Airport (STL)
• Washington-Dulles International Airport (IAD)

 

Volvo announced that it would use cameras installed inside its vehicles to monitor driver behavior and intervene if the driver appears to be drunk or distracted. It’s a risky move by an automaker, even one with a reputation for safety like Volvo, which could raise concerns among privacy advocates. 

Volvo’s in-car cameras will monitor eye movements to gauge driver distraction or intoxication. If a driver looks away for some time, such as at a smartphone, or fails to keep their hands on the steering wheel, a representative from Volvo’s on-call assistance centers will call them to check in. Drivers who aren’t watching the road, or even have their eyes closed, will be warned as well. If they don’t respond, the car will slow and also stop. The system will roll-out to all Volvo cars by early 2020. 

This follows Volvo’s recent announcement that it will be limiting the top speed on all of its vehicles to 180 km/h (112 mph) in a bid to reduce traffic fatalities. Volvo is framing these new policies as crucial components in its Vision 2020goal, in which no one is killed or seriously injured in a Volvo vehicle by 2020. Over the years, the company built its reputation on safety and quirky designs, and today’s announcement is meant to underline that.

“When it comes to safety, our aim is to avoid accidents altogether rather than limit the impact when an accident is imminent and unavoidable,” Henrik Green, senior vice president for research and development at Volvo Car Group, said in a statement. “In this case, cameras will monitor for behavior that may lead to serious injury or death.”

The use of in-car cameras to monitor drivers is not entirely unprecedented. Cadillac uses infrared cameras facing the driver to power its advanced driver assist system, Super Cruise. The camera tracks the driver’s eye movements, allowing for a “hands-free” driving experience. If the driver’s attention wanders, Super Cruise uses an escalating series of audible and vibrating alerts to ensure the driver keeps their eyes on the road.

As camera use increases in the name of safety, there’s a real chance they can be misused to invade privacy. At an event in Sweden, the company preemptively dismissed this criticism by likening it to early objection to seatbelt laws. 

A spokesperson for Volvo did not immediately respond to questions about the storage of video footage or whether law enforcement could have access to it. Automakers are already collecting lots of information from your car today, but mostly for vehicle analytics. 
​
GM has said that the camera in its Cadillac cars isn’t recording anything; it’s just a buffered video feed to make sure Super Cruise works as it should.

Drivers will soon have an extra set of eyes on the road, courtesy of Google.

Google’s navigation app, Google Maps, is starting to roll out speed limit and speed trap features. 

With the speed limit feature, drivers using Google Maps will be shown the posted speed limit of the road they’re driving on in the lower left side of the app. Speed traps are designated with a small camera icon and shown on the visible area of the map. The Maps app provides an audio warning for drivers when they are approaching a speed trap.

Users have had the ability to report speed traps in Google Maps since late last year. However, until now, the app wasn’t yet making the reported speed traps visible for users in maps. 

Google Maps users have long wondered when such features were going to make their debut on the service. Crowdsource-powered navigation app, Waze, grew in popularity for providing this sort of detailed information on the road. Google acquired Waze back in 2013 for around $1 billion. 

Now, nearly five and a half years later, some of the Waze features are finally making their way to Google Maps.

Several companies demonstrated C-V2X (cellular vehicle-to-everything)communications technology developed by Qualcomm at CES 2019. But Ford may be the most aggressive in bringing C-V2X to market. The Detroit automaker will add it to every new car and truck sold in the United States by 2022, Don Butler, executive director for Ford connected vehicle platform and product, wrote in a blog post.

C-V2X is the latest incarnation of so-called vehicle-to-everything (V2X), a communications technology that allows cars to “talk” to each other and infrastructure. The claimed advantage of this technology is that it can warn a driver of things beyond his or her line of sight. If a car is stopped at an intersection with poor visibility, it could, for example, pick up signals from other V2X-equipped cars or sensors mounted on nearby buildings to tell the driver if it’s okay to go.

Vehicles could also communicate with stoplights, telling drivers when a light is about to change. Audi already offers this in the form of its Traffic Light Information system. The system gives a countdown when a light is about to turn green, but it only works in a handful of cities (Audi also offers a built-in toll transponder that relies on V2X tech). Aptiv has placed sensors on traffic lights in Las Vegas to guide its self-driving cars, even when they’re onboard cameras don’t have a direct line of sight to the light.

Ford could take things even further, Butler wrote. C-V2X could be integrated with driver aids, like those in Ford’s recently introduced Co-Pilot360 suite. Or it could be added to self-driving cars. Emergency vehicles could be equipped with C-V2X transmitters, allowing cars to detect their presence and move out of the way.

The difference between the C-V2X tech embraced by Ford and previous systems is that it’s based on 5G. All other V2X systems to-date have used a competing setup called Dedicated Short-Range Communications (DSRC). But that means Ford will have to rely on the smooth rollout of 5G. Even the deployment of DSRC-based V2X vehicles and infrastructure has been slow, and DSRC is based on a more familiar technology derived from Wi-Fi.

“A conducive regulatory environment must be in place for C-V2X to be deployed, which is why we are working just as much with industry and government organizations to create such a technology-neutral environment,” Butler wrote in his blog post. He also told Bloombergthat he hopes other automakers will adopt C-V2X alongside Ford. He added that C-V2X is a simpler solution because telecom companies are already spending billions on 5G cell towers and antennas, while DSRC would require a separate government investment.
​
Despite the potential hurdles, Qualcomm expects C-V2X and other related technologies to become a significant part of its business. The company believes that, within five years, 75% of cars will have some form of connectivity. A critical mass of vehicles will be needed to realize the technology’s full benefit since cars that aren’t equipped with C-V2X or similar systems can’t communicate with each other. The more vehicles on the network, the more effective it is.

British scientists have developed a self-contained and tamper-proof "quantum compass" that doesn't rely on GPS signals to provide a highly accurate measure of where it is in the world.

The compass is a quantum accelerometer that is capable of measuring tiny shifts in supercooled atoms and so calculate how far and how fast the device has moved. Having a device like the quantum compass aboard a ship, the captain knows exactly where his ship is without having to rely on orbiting satellites.

The system has been designed by quantum physicistsat Imperial College, London – who developed a laser system for cooling atoms down and at photonics and quantum technology specialist firm M Squared– which developed another laser system to act as an “optical ruler.” Their work has been funded by the UK's Ministry of Defense.

Although GPS satellites are a modern marvel and are used by just about everyone to identify their precise location, the fact is the system is not perfect.

A phone's GPS is accurate to roughly 15 feet, although military GPS devices can be accurate to centimeters. Then there is the fact that tall buildings will often throw a signal off and signals can be impaired by any large, dense object.

But that's not why the Ministry of Defense is interested in a quantum compass: its concern is that the GPS system is vulnerable to attack or deliberate disruption. A GPS signal could be spoofed or blocked for instance. When you're thinking about nuclear submarines, it's usually best to consider the worst.

“Pirates are now sophisticated enough to cause disruptions to ships’ GPS systems and lure them to rocks or take over and board them,” said Graeme Malcolm, the CEO of M Squared.

“They can be an even bigger issue in areas of defense and security, where the resilience and security of cities and countries are impacted. This new device is an absolute reference that goes down to the atomic level.”

Accuracy. This is not the first time that accelerometers have been used for navigation, but the reality is that such systems are not sufficiently accurate, meaning that as time goes on the system becomes increasingly out of whack and requires recalibration.

Not so with the quantum compass, according to its makers. Lasers are used to supercool atoms, and then another laser is used to act as "optical ruler" measuring how far those atoms have moved. At extremely low temperatures, atoms behave in a ‘quantum’ way, acting like both matter and waves.

Here's how Dr. Joseph Cotter, from the Centre for Cold Matter at Imperial College, explained it: "When the atoms are ultra-cold, we have to use quantum mechanics to describe how they move, and this allows us to make what we call an atom interferometer."

As the atoms move, their wave properties are affected by the acceleration of the vehicle. The optical ruler can measure these minute changes very accurately and then with a few relatively simple equations it is possible to figure out exactly where you are.

Size. But this is not something you're going to find in your smartphone: the prototype system is about three-feet wide and high, and it is incredibly expensive.
​
Plus, it can currently only measure in one plane. The scientists say they will soon be able to take measurements in three planes – making it an entirely independent super compass that can tell you where exactly it is at any point.

Every election season, Uber and Lyft jockey for the position of the most civic-minded ride-hailing company by offering various promotions, like free and discounted rides to polling places. This year, both companies are trying something new. On November 6th, Uber will add a new button in its app that will help people find and book rides to their polling place. It’s an extra step that Uber says it hopes will help get out the vote. Lyft also promises something similar. 

Uber. The poll locator will be available to anyone who lives in the US, but it’s targeted at suburban or exurban voters who tend to live outside of walking distance of their polling location. There are a variety of websites where voters can go to find their polling information but pairing that with a transportation service could help bridge the gap between the intention to vote and going to the polls. 

Lyft. The San Francisco-based ride service is also aiming to help its customers find their polling location. The company said in a recent announcement that it would release a “product integration to help passengers find their polling location.” It didn’t, however, specify what that integration would look like.

Surveys indicate that voter enthusiasm is at an all-time high this year, but if history is any indicator, most eligible voters will stay home. Slightly more than one-third of eligible voters turned out across the country in the last midterm elections.

Uber is hoping it can make a small contribution to turnout. “Using our technology and resources, we can help make it easier for every Uber rider in the US to get to their polling place at the push of a button,” Uber CEO Dara Khosrowshahi said in a blog post.

The ride-hail company will also partner with two GOTV organizations, #VoteTogether and Democracy Works, to provide free rides to voters in specific communities. Uber will also help register riders and drivers to vote by sharing voter registration information through the app. An email went out to all Uber drivers this week encouraging them to visit one of Uber’s 125 Greenlight Hubs where they can register to vote. 
​
In August, Lyft saidit planned to give away 50 percent off promo codes with GOTV partners to encourage voter turnout. Neither Uber nor Lyft would say how many free and discounted rides they plan on distributing.
