Apple is going bullish on lidar, a technology that’s brand-new to the iPhone 12 family, specifically to the iPhone 12 Pro and iPhone 12 Pro Max. (All four iPhone 12 variants, including the iPhone 12 Mini, are on sale now.) Peer closely at one of the new iPhone 12 Pro models, or the most recent iPad Pro, and you’ll see a little black dot near the camera lenses, about the same size as the flash. That’s the lidar sensor, and it’s a new type of depth-sensing that could make a difference in a number of interesting ways.

If Apple has its way, lidar is a term you’ll start hearing a lot now, so let’s break down what we know, what Apple is going to use it for and where the technology could go next. And if you’re curious what it does right now, I spent some hands-on time with the tech, too.

What does lidar mean?

Lidar stands for light detection and ranging, and has been around for a while. It uses lasers to ping off objects and return to the source of the laser, measuring distance by timing the travel, or flight, of the light pulse. 

How does lidar work to sense depth?

Lidar is a type of time-of-flight camera. Some other smartphones measure depth with a single light pulse, whereas a smartphone with this type of lidar tech sends waves of light pulses out in a spray of infrared dots and can measure each one with its sensor, creating a field of points that map out distances and can “mesh” the dimensions of a space and the objects in it. The light pulses are invisible to the human eye, but you could see them with a night vision camera.

Isn’t this like Face ID on the iPhone?

It is, but with longer range. The idea’s the same: Apple’s Face ID-enabling TrueDepth camera also shoots out an array of infrared lasers, but can only work up to a few feet away. The rear lidar sensors on the iPad Pro and iPhone 12 Pro work at a range of up to 5 meters.

Lidar’s already in a lot of other tech

Lidar is a tech that’s sprouting up everywhere. It’s used for self-driving cars, or assisted driving. It’s used for robotics and drones. Augmented reality headsets like the HoloLens 2 have similar tech, mapping out room spaces before layering 3D virtual objects into them. But it also has a pretty long history. 

Microsoft’s old depth-sensing Xbox accessory, the Kinect, was a camera that had infrared depth-scanning, too. In fact, PrimeSense, the company that helped make the Kinect tech, was acquired by Apple in 2013. Now, we have Apple’s face-scanning TrueDepth and rear lidar camera sensors.

The iPhone 12 Pro camera works better with lidar

Time-of-flight cameras on smartphones tend to be used to improve focus accuracy and speed, and the iPhone 12 Pro does the same. Apple promises better low-light focus, up to six times faster in low-light conditions. The lidar depth-sensing is also used to improve night portrait mode effects. So far, it makes an impact: read our review of the iPhone 12 Pro for more.

Better focus is a plus, and there’s also a chance the iPhone 12 Pro could add more 3D photo data to images, too. Although that element hasn’t been laid out yet, Apple’s front-facing, depth-sensing TrueDepth camera has been used in a similar way with apps, and third-party developers could dive in and develop some wild ideas. It’s already happening.

It also greatly enhances augmented reality

Lidar allows the iPhone 12 Pro to start AR apps a lot more quickly, and build a fast map of a room to add more detail. A lot of Apple’s AR updates in iOS 14 are taking advantage of lidar to hide virtual objects behind real ones (called occlusion), and place virtual objects within more complicated room mappings, like on a table or chair.

I’ve been testing it out on an Apple Arcade game, Hot Lava, which already uses lidar to scan a room and all its obstacles. I was able to place virtual objects on stairs, and have things hide behind real-life objects in the room. Expect a lot more AR apps that will start adding lidar support like this for richer experiences.

Snapchat’s next wave of lenses will start adopting depth-sensing using the iPhone 12 Pro’s lidar.

But there’s extra potential beyond that, with a longer tail. Many companies are dreaming of headsets that will blend virtual objects and real ones: AR glasses, being worked on by Facebook, Qualcomm, Snapchat, Microsoft, Magic Leap and most likely Apple and others, will rely on having advanced 3D maps of the world to layer virtual objects onto.

Those 3D maps are being built now with special scanners and equipment, almost like the world-scanning version of those Google Maps cars. But there’s a possibility that people’s own devices could eventually help crowdsource that info, or add extra on-the-fly data. Again, AR headsets like Magic Leap and HoloLens already prescan your environment before layering things into it, and Apple’s lidar-equipped AR tech works the same way. In that sense, the iPhone 12 Pro and iPad Pro are like AR headsets without the headset part… and could pave the way for Apple to make its own glasses eventually.

3D scanning could be the killer app

Lidar can be used to mesh out 3D objects and rooms and layer photo imagery on top, a technique called photogrammetry. That could be the next wave of capture tech for practical uses like home improvement, or even social media and journalism. The ability to capture 3D data and share that info with others could open up these lidar-equipped phones and tablets to be 3D-content capture tools. Lidar could also be used without the camera element to acquire measurements for objects and spaces.

I’ve already tried a few early lidar-enabled 3D scanning apps on the iPhone 12 Pro with mixed success (3D Scanner App, Lidar Scanner and Record3D), but they can be used to scan objects or map out rooms with surprising speed. The 16-foot effective range of lidar’s scanning is enough to reach across most rooms in my house, but in bigger outdoor spaces it takes more moving around. Again, Apple’s front-facing TrueDepth camera already does similar things at closer range.

Apple isn’t the first to explore tech like this on a phone

Google had this same idea in mind when Project Tango — an early AR platform that was only on two phones — was created. The advanced camera array also had infrared sensors and could map out rooms, creating 3D scans and depth maps for AR and for measuring indoor spaces. Google’s Tango-equipped phones were short-lived, replaced by computer vision algorithms that have done estimated depth sensing on cameras without needing the same hardware. But Apple’s iPhone 12 Pro looks like a significantly more advanced successor, with possibilities for that lidar that extend into cars, AR headsets, and much more.

The Internet is Littered in ‘Educated Guesses’ Without the ‘Education’

Published

 on

Although no one likes a know-it-all, they dominate the Internet.

The Internet began as a vast repository of information. It quickly became a breeding ground for self-proclaimed experts seeking what most people desire: recognition and money.

Today, anyone with an Internet connection and some typing skills can position themselves, regardless of their education or experience, as a subject matter expert (SME). From relationship advice, career coaching, and health and nutrition tips to citizen journalists practicing pseudo-journalism, the Internet is awash with individuals—Internet talking heads—sharing their “insights,” which are, in large part, essentially educated guesses without the education or experience.

The Internet has become a 24/7/365 sitcom where armchair experts think they’re the star.

Not long ago, years, sometimes decades, of dedicated work and acquiring education in one’s field was once required to be recognized as an expert. The knowledge and opinions of doctors, scientists, historians, et al. were respected due to their education and experience. Today, a social media account and a knack for hyperbole are all it takes to present oneself as an “expert” to achieve Internet fame that can be monetized.

On the Internet, nearly every piece of content is self-serving in some way.

The line between actual expertise and self-professed knowledge has become blurry as an out-of-focus selfie. Inadvertently, social media platforms have created an informal degree program where likes and shares are equivalent to degrees. After reading selective articles, they’ve found via and watching some TikTok videos, a person can post a video claiming they’re an herbal medicine expert. Their new “knowledge,” which their followers will absorb, claims that Panda dung tea—one of the most expensive teas in the world and isn’t what its name implies—cures everything from hypertension to existential crisis. Meanwhile, registered dietitians are shaking their heads, wondering how to compete against all the misinformation their clients are exposed to.

More disturbing are individuals obsessed with evangelizing their beliefs or conspiracy theories. These people write in-depth blog posts, such as Elvis Is Alive and the Moon Landings Were Staged, with links to obscure YouTube videos, websites, social media accounts, and blogs. Regardless of your beliefs, someone or a group on the Internet shares them, thus confirming your beliefs.

Misinformation is the Internet’s currency used to get likes, shares, and engagement; thus, it often spreads like a cosmic joke. Consider the prevalence of clickbait headlines:

  • You Won’t Believe What Taylor Swift Says About Climate Change!
  • This Bedtime Drink Melts Belly Fat While You Sleep!
  • In One Week, I Turned $10 Into $1 Million!

Titles that make outrageous claims are how the content creator gets reads and views, which generates revenue via affiliate marketing, product placement, and pay-per-click (PPC) ads. Clickbait headlines are how you end up watching a TikTok video by a purported nutrition expert adamantly asserting you can lose belly fat while you sleep by drinking, for 14 consecutive days, a concoction of raw eggs, cinnamon, and apple cider vinegar 15 minutes before going to bed.

Our constant search for answers that’ll explain our convoluted world and our desire for shortcuts to success is how Internet talking heads achieve influencer status. Because we tend to seek low-hanging fruits, we listen to those with little experience or knowledge of the topics they discuss yet are astute enough to know what most people want to hear.

There’s a trend, more disturbing than spreading misinformation, that needs to be called out: individuals who’ve never achieved significant wealth or traded stocks giving how-to-make-easy-money advice, the appeal of which is undeniable. Several people I know have lost substantial money by following the “advice” of Internet talking heads.

Anyone on social media claiming to have a foolproof money-making strategy is lying. They wouldn’t be peddling their money-making strategy if they could make easy money.

Successful people tend to be secretive.

Social media companies design their respective algorithms to serve their advertisers—their source of revenue—interest; hence, content from Internet talking heads appears most prominent in your feeds. When a video of a self-professed expert goes viral, likely because it pressed an emotional button, the more people see it, the more engagement it receives, such as likes, shares and comments, creating a cycle akin to a tornado.

Imagine scrolling through your TikTok feed and stumbling upon a “scientist” who claims they can predict the weather using only aluminum foil, copper wire, sea salt and baking soda. You chuckle, but you notice his video got over 7,000 likes, has been shared over 600 times and received over 400 comments. You think to yourself, “Maybe this guy is onto something.” What started as a quest to achieve Internet fame evolved into an Internet-wide belief that weather forecasting can be as easy as DIY crafts.

Since anyone can call themselves “an expert,” you must cultivate critical thinking skills to distinguish genuine expertise from self-professed experts’ self-promoting nonsense. While the absurdity of the Internet can be entertaining, misinformation has serious consequences. The next time you read a headline that sounds too good to be true, it’s probably an Internet talking head making an educated guess; without the education seeking Internet fame, they can monetize.

Tight deadlines on software projects can put safety at risk: survey

Published

 on

 

TORONTO – A new survey says a majority of software engineers and developers feel tight project deadlines can put safety at risk.

Seventy-five per cent of the 1,000 global workers who responded to the survey released Tuesday say pressure to deliver projects on time and on budget could be compromising critical aspects like safety.

The concern is even higher among engineers and developers in North America, with 77 per cent of those surveyed on the continent reporting the urgency of projects could be straining safety.

The study was conducted between July and September by research agency Coleman Parkes and commissioned by BlackBerry Ltd.’s QNX division, which builds connected-car technology.

The results reflect a timeless tug of war engineers and developers grapple with as they balance the need to meet project deadlines with regulations and safety checks that can slow down the process.

Finding that balance is an issue that developers of even the simplest appliances face because of advancements in technology, said John Wall, a senior vice-president at BlackBerry and head of QNX.

“The software is getting more complicated and there is more software whether it’s in a vehicle, robotics, a toaster, you name it… so being able to patch vulnerabilities, to prevent bad actors from doing malicious acts is becoming more and more important,” he said.

The medical, industrial and automotive industries have standardized safety measures and anything they produce undergoes rigorous testing, but that work doesn’t happen overnight. It has to be carried out from the start and then at every step of the development process.

“What makes safety and security difficult is it’s an ongoing thing,” Wall said. “It’s not something where you’ve done it, and you are finished.”

The Waterloo, Ont.-based business found 90 per cent of its survey respondents reported that organizations are prioritizing safety.

However, when asked about why safety may not be a priority for their organization, 46 per cent of those surveyed answered cost pressures and 35 per cent said a lack of resources.

That doesn’t surprise Wall. Delays have become rampant in the development of tech, and in some cases, stand to push back the launch of vehicle lines by two years, he said.

“We have to make sure that people don’t compromise on safety and security to be able to get products out quicker,” he said.

“What we don’t want to see is people cutting corners and creating unsafe situations.”

The survey also took a peek at security breaches, which have hit major companies like London Drugs, Indigo Books & Music, Giant Tiger and Ticketmaster in recent years.

About 40 per cent of the survey’s respondents said they have encountered a security breach in their employer’s operating system. Those breaches resulted in major impacts for 27 per cent of respondents, moderate impacts for 42 per cent and minor impacts for 27 per cent.

“There are vulnerabilities all the time and this is what makes the job very difficult because when you ship the software, presumably the software has no security vulnerabilities, but things get discovered after the fact,” Wall said.

Security issues, he added, have really come to the forefront of the problems developers face, so “really without security, you have no safety.”

Beware of scams during Amazon’s Prime Big Deal Days sales event: cybersecurity firm

Published

 on

 

As online shoppers hunt for bargains offered by Amazon during its annual fall sale this week, cybersecurity researchers are warning Canadians to beware of an influx of scammers posing as the tech giant.

In the 30 days leading up to Amazon’s Prime Big Deal Days, taking place Tuesday and Wednesday, there were more than 1,000 newly registered Amazon-related web domains, according to Check Point Software Technologies, a company that offers cybersecurity solutions.

The company said it deemed 88 per cent of those domains malicious or suspicious, suggesting they could have been set up by scammers to prey on vulnerable consumers. One in every 54 newly created Amazon-related domain included the phrase “Amazon Prime.”

“They’re almost indiscernible from the real Amazon domain,” said Robert Falzon, head of engineering at Check Point in Canada.

“With all these domains registered that look so similar, it’s tricking a lot of people. And that’s the whole intent here.”

Falzon said Check Point Research sees an uptick in attempted scams around big online shopping days throughout the year, including Prime Days.

Scams often come in the form of phishing emails, which are deceptive messages that appear to be from a reputable source in attempt to steal sensitive information.

In this case, he said scammers posing as Amazon commonly offer “outrageous” deals that appear to be associated with Prime Days, in order to trick recipients into clicking on a malicious link.

The cybersecurity firm said it has identified and blocked 100 unique Amazon Prime-themed scam emails targeting organizations and consumers over the past two weeks.

Scammers also target Prime members with unsolicited calls, claiming urgent account issues and requesting payment information.

“It’s like Christmas for them,” said Falzon.

“People expect there to be significant savings on Prime Day, so they’re not shocked that they see something of significant value. Usually, the old adage applies: If it seems too good to be true, it probably is.”

Amazon’s website lists a number of red flags that it recommends customers watch for to identify a potential impersonation scam.

Those include false urgency, requests for personal information, or indications that the sender prefers to complete the purchase outside of the Amazon website or mobile app.

Scammers may also request that customers exclusively pay with gift cards, a claim code or PIN. Any notifications about an order or delivery for an unexpected item should also raise alarm bells, the company says.

“During busy shopping moments, we tend to see a rise in impersonation scams reported by customers,” said Amazon spokeswoman Octavia Roufogalis in a statement.

“We will continue to invest in protecting consumers and educating the public on scam avoidance. We encourage consumers to report suspected scams to us so that we can protect their accounts and refer bad actors to law enforcement to help keep consumers safe.”

Falzon added that these scams are more successful than people might think.

As of June 30, the Canadian Anti-Fraud Centre said there had been $284 million lost to fraud so far this year, affecting 15,941 victims.

But Falzon said many incidents go unreported, as some Canadians who are targeted do not know how or where to flag a scam, or may choose not to out of embarrassment.

Check Point recommends Amazon customers take precautions while shopping on Prime Days, including by checking URLs carefully, creating strong passwords on their accounts, and avoiding personal information being shared such as their birthday or social security number.

The cybersecurity company said consumers should also look for “https” at the beginning of a website URL, which indicates a secure connection, and use credit cards rather than debit cards for online shopping, which offer better protection and less liability if stolen.
