iPhone 12 Pro camera uses lidar. What that is and why it matters – CNET

The iPhone 12 Pro’s lidar sensor — the black circle at the bottom right of the camera unit — opens up AR possibilities.


Apple

The iPhone 12 and 12 Pro are on sale now, but one of the key differences between the Pro and non-Pro models this year is a depth-sensing technology. If you look closely at one of the new iPhone 12 Pros, or the most recent iPad Pro, you’ll see a little black dot near the camera lenses, about the same size as the flash. That’s a lidar sensor. Apple’s been bullish about lidar as a way of adding depth-sensing and new augmented reality features to its pro-end tablets and phones. It could help a lot with camera focus, too.

But why is Apple making a big deal about lidar and what will it be able to do if you buy the iPhone 12 Pro or iPhone 12 Pro Max? It’s a term that you’ll start hearing a lot right now, so let’s break down what we know, what Apple is going to use it for, and where the tech could go next.

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. Already on some other smartphones, they often measure depth with a single light pulse, whereas lidar 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.

The iPad Pro released in the spring also has lidar.

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.

Remember the Kinect?

The iPhone 12 Pro camera could work better with lidar

Time-of-flight cameras on smartphones tend to be used to improve focus accuracy and speed, and the iPhone 12 Pro will do the same. Apple promises better low-light focus: Apple says it’ll be up to 6x faster in low-light conditions. The lidar depth-sensing will also be used to improve night portrait mode effects.

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.

Snapchat’s already enabling AR lenses using the iPhone 12 Pro’s lidar.

It will also greatly enhance augmented reality

Lidar will allow 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.

But there’s an extra potential beyond that, with a longer tail. Many companies are dreaming of headsets that will blend virtual objects and real ones: These 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. 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 things 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.

Remember Google Tango? It had depth-sensing, too.

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 the much more advanced successor.

Here is how to prepare your online accounts for when you die

Published

 on

 

LONDON (AP) — Most people have accumulated a pile of data — selfies, emails, videos and more — on their social media and digital accounts over their lifetimes. What happens to it when we die?

It’s wise to draft a will spelling out who inherits your physical assets after you’re gone, but don’t forget to take care of your digital estate too. Friends and family might treasure files and posts you’ve left behind, but they could get lost in digital purgatory after you pass away unless you take some simple steps.

Here’s how you can prepare your digital life for your survivors:

Apple

The iPhone maker lets you nominate a “ legacy contact ” who can access your Apple account’s data after you die. The company says it’s a secure way to give trusted people access to photos, files and messages. To set it up you’ll need an Apple device with a fairly recent operating system — iPhones and iPads need iOS or iPadOS 15.2 and MacBooks needs macOS Monterey 12.1.

For iPhones, go to settings, tap Sign-in & Security and then Legacy Contact. You can name one or more people, and they don’t need an Apple ID or device.

You’ll have to share an access key with your contact. It can be a digital version sent electronically, or you can print a copy or save it as a screenshot or PDF.

Take note that there are some types of files you won’t be able to pass on — including digital rights-protected music, movies and passwords stored in Apple’s password manager. Legacy contacts can only access a deceased user’s account for three years before Apple deletes the account.

Google

Google takes a different approach with its Inactive Account Manager, which allows you to share your data with someone if it notices that you’ve stopped using your account.

When setting it up, you need to decide how long Google should wait — from three to 18 months — before considering your account inactive. Once that time is up, Google can notify up to 10 people.

You can write a message informing them you’ve stopped using the account, and, optionally, include a link to download your data. You can choose what types of data they can access — including emails, photos, calendar entries and YouTube videos.

There’s also an option to automatically delete your account after three months of inactivity, so your contacts will have to download any data before that deadline.

Facebook and Instagram

Some social media platforms can preserve accounts for people who have died so that friends and family can honor their memories.

When users of Facebook or Instagram die, parent company Meta says it can memorialize the account if it gets a “valid request” from a friend or family member. Requests can be submitted through an online form.

The social media company strongly recommends Facebook users add a legacy contact to look after their memorial accounts. Legacy contacts can do things like respond to new friend requests and update pinned posts, but they can’t read private messages or remove or alter previous posts. You can only choose one person, who also has to have a Facebook account.

You can also ask Facebook or Instagram to delete a deceased user’s account if you’re a close family member or an executor. You’ll need to send in documents like a death certificate.

TikTok

The video-sharing platform says that if a user has died, people can submit a request to memorialize the account through the settings menu. Go to the Report a Problem section, then Account and profile, then Manage account, where you can report a deceased user.

Once an account has been memorialized, it will be labeled “Remembering.” No one will be able to log into the account, which prevents anyone from editing the profile or using the account to post new content or send messages.

X

It’s not possible to nominate a legacy contact on Elon Musk’s social media site. But family members or an authorized person can submit a request to deactivate a deceased user’s account.

Passwords

Besides the major online services, you’ll probably have dozens if not hundreds of other digital accounts that your survivors might need to access. You could just write all your login credentials down in a notebook and put it somewhere safe. But making a physical copy presents its own vulnerabilities. What if you lose track of it? What if someone finds it?

Instead, consider a password manager that has an emergency access feature. Password managers are digital vaults that you can use to store all your credentials. Some, like Keeper,Bitwarden and NordPass, allow users to nominate one or more trusted contacts who can access their keys in case of an emergency such as a death.

But there are a few catches: Those contacts also need to use the same password manager and you might have to pay for the service.

Google’s partnership with AI startup Anthropic faces a UK competition investigation

Published

 on

 

LONDON (AP) — Britain’s competition watchdog said Thursday it’s opening a formal investigation into Google’s partnership with artificial intelligence startup Anthropic.

The Competition and Markets Authority said it has “sufficient information” to launch an initial probe after it sought input earlier this year on whether the deal would stifle competition.

The CMA has until Dec. 19 to decide whether to approve the deal or escalate its investigation.

“Google is committed to building the most open and innovative AI ecosystem in the world,” the company said. “Anthropic is free to use multiple cloud providers and does, and we don’t demand exclusive tech rights.”

San Francisco-based Anthropic was founded in 2021 by siblings Dario and Daniela Amodei, who previously worked at ChatGPT maker OpenAI. The company has focused on increasing the safety and reliability of AI models. Google reportedly agreed last year to make a multibillion-dollar investment in Anthropic, which has a popular chatbot named Claude.

Anthropic said it’s cooperating with the regulator and will provide “the complete picture about Google’s investment and our commercial collaboration.”

“We are an independent company and none of our strategic partnerships or investor relationships diminish the independence of our corporate governance or our freedom to partner with others,” it said in a statement.

The U.K. regulator has been scrutinizing a raft of AI deals as investment money floods into the industry to capitalize on the artificial intelligence boom. Last month it cleared Anthropic’s $4 billion deal with Amazon and it has also signed off on Microsoft’s deals with two other AI startups, Inflection and Mistral.

Kuwait bans ‘Call of Duty: Black Ops 6’ video game, likely over it featuring Saddam Hussein in 1990s

Published

 on

 

DUBAI, United Arab Emirates (AP) — The tiny Mideast nation of Kuwait has banned the release of the video game “Call of Duty: Black Ops 6,” which features the late Iraqi dictator Saddam Hussein and is set in part in the 1990s Gulf War.

Kuwait has not publicly acknowledged banning the game, which is a tentpole product for the Microsoft-owned developer Activision and is set to be released on Friday worldwide. However, it comes as Kuwait still wrestles with the aftermath of the invasion and as video game makers more broadly deal with addressing historical and cultural issues in their work.

The video game, a first-person shooter, follows CIA operators fighting at times in the United States and also in the Middle East. Game-play trailers for the game show burning oilfields, a painful reminder for Kuwaitis who saw Iraqis set fire to the fields, causing vast ecological and economic damage. Iraqi troops damaged or set fire to over 700 wells.

There also are images of Saddam and Iraq’s old three-star flag in the footage released by developers ahead of the game’s launch. The game’s multiplayer section, a popular feature of the series, includes what appears to be a desert shootout in Kuwait called Scud after the Soviet missiles Saddam fired in the war. Another is called Babylon, after the ancient city in Iraq.

Activision acknowledged in a statement that the game “has not been approved for release in Kuwait,” but did not elaborate.

“All pre-orders in Kuwait will be cancelled and refunded to the original point of purchase,” the company said. “We remain hopeful that local authorities will reconsider, and allow players in Kuwait to enjoy this all-new experience in the Black Ops series.”

Kuwait’s Media Ministry did not respond to requests for comment from The Associated Press over the decision.

“Call of Duty,” which first began in 2003 as a first-person shooter set in World War II, has expanded into an empire worth billions of dollars now owned by Microsoft. But it also has been controversial as its gameplay entered the realm of geopolitics. China and Russia both banned chapters in the franchise. In 2009, an entry in the gaming franchise allowed players to take part in a militant attack at a Russian airport, killing civilians.

But there have been other games recently that won praise for their handling of the Mideast. Ubisoft’s “Assassin’s Creed: Mirage” published last year won praise for its portrayal of Baghdad during the Islamic Golden Age in the 9th century.
