What is a LiDAR scanner, the iPhone 12 Pro's rumored camera upgrade, anyway? – TechRadar

The iPhone 12‘s camera specs might still be up in the air, but there is one thing we are pretty sure about – the phone’s two ‘Pro’ versions are likely to come with a LiDAR scanner. That’s right, the same mysterious dot that first appeared on the iPad Pro 2020.

But what is a LiDAR scanner? A built-in lie detector? A more relaxed version of radar perhaps? As we’ll discover, LiDAR (or ‘Light Detection and Ranging’) does work in a similar way to radar, only it uses lasers to judge distances and depth. This is big news for augmented reality (AR) and, to a lesser extent, photography too.

The more interesting question, though, is what LiDAR will let us do on the iPhone 12. Using our experience of seeing the tech on the iPad Pro 2020, we’ll be exploring the kind of experiences LiDAR could open up on the new iPhones – and, ultimately, the Apple Glasses.

But first, a quick rewind to the tech’s origins, so you can sound smart during your next family Zoom meeting…

What is LiDAR?

The concept behind LiDAR has been around since the 1960s. In short, the tech lets you scan and map your environment by firing out laser beams, then timing how quickly they return. A bit like how bats ‘see’ with sound waves, only with lasers –which makes it even cooler than Batman’s Batarang.

Like most futuristic tech, it started life as a military tool on planes, before becoming better known as the system that allowed the Apollo 15 mission to map the surface of the moon.

More recently, LiDAR (also known as lidar) has been seen on self-driving cars, where it helps detect objects like cyclists and pedestrians. You might have also unwittingly come across the tech in your robot vacuum.

But it’s in the past couple of years that LiDAR’s possibilities have really opened up. With the systems getting smaller, cheaper and more accurate, they’ve started become viable additions to mobile devices that already have things like powerful processors and GPS – tablets and phones.

Of course, not all LiDAR systems are created equal. Until fairly recently, the most common types built 3D maps of their environments by physically sweeping around in a similar way to a radar dish.

This obviously won’t cut it on mobile devices, so newer LiDAR systems – including the 3D time-of-flight (ToF) sensors seen on many smartphones – are solid-state affairs with no moving parts. But what’s the difference between a time-of-flight sensor and the LiDAR ‘scanner’ that we’ll mostly likely see on the iPhone 12?

What’s different about Apple’s LiDAR scanner?

You might already be familiar with the time-of-flight (ToF) sensors seen on many Android phones – these help them sense scene depth and mimic the bokeh effects of larger cameras.

But the LiDAR system used in the iPad Pro 2020 – and, most likely, the two ‘Pro’ versions of the iPhone 12 – promises to go beyond this. That’s because it’s a LiDAR scanner, rather than the ‘scannerless’ systems seen on smartphones so far.

The latter use a single pulse of infra-red light to create their 3D maps, but a scanning LiDAR system fires a train of laser pulses at different parts of a scene over a short period of time. This brings two main benefits – an improved range of up to five meters and better object ‘occlusion’, which is the appearance of virtual objects disappearing behind real ones like trees.

Impressively, it’s a speedy process too, but that speed is only really possible with the latest mobile processors. As Apple stated at the iPad Pro 2020 launch, the LiDAR scanner’s data is crunched together with data from cameras and a motion sensor, then “enhanced by computer vision algorithms on the A12Z Bionic for a more detailed understanding of the scene”. In other words, there’s a lot going on to make it appear seamless.

But while the iPhone 12’s rumored A14 Bionic processor would offer good support for Apple’s LiDAR scanner, there’s plenty of room for improvement in the scanner itself too.

As a blog post from the developer of Halide camera app points out, right now the iPad Pro’s depth data just doesn’t offer the resolution needed for some applications, like detailed 3D scanning or even Portrait mode.

This means the iPad Pro’s LiDAR scanner is designed more for room-scale applications like games or shifting around AR furniture in IKEA’s Place app. It doesn’t currently let you 3D scan objects with greater accuracy than other techniques like photogrammetry, which instead combines high-resolution RGB photos taken from different vantage points.

Wouldn’t it be great if these LiDAR scanner meshes could be combined with the kind of resolution and textures seen by RGB cameras or Face ID? That’s the ideal, but we’re not quite there yet – and it’s unlikely that the iPhone 12 will immediately make that leap either.

So what exactly might you be able to do with a LiDAR scanner on the iPhone 12?

What might a LiDAR scanner let you do on the iPhone 12?

So now we know the iPad Pro’s LiDAR scanner works best at room-sized scales, what kind of things could it do on the iPhone 12? For the average person, the main two are AR gaming and AR shopping.

Apple has previewed a few LiDAR-specific applications that are conveniently coming “later this year” (most likely to tie in with the iPhone 12’s announcement) and one of the more interesting is the game Hot Lava.

A first-person adventure game for iOS and PC, Hot Lava will have a new ‘AR mode’ in late 2020 that draws on Apple’s LiDAR sensor to bring its molten rivers into your living room.

So far, the demo isn’t quite as impressive as we’d hoped – most of the objects that your character leaps around are in-game renders rather than your actual furniture, but there’s still time for it to develop.

Naturally, any mention of AR gaming brings to mind Pokemon Go, the only real smash hit for augmented reality so far. Interestingly, the game’s maker Niantic seems to be forging its own AR path, rather than relying on Apple’s tech. It recently announced a new ‘reality blending’ feature for Pokemon Go – which lets characters realistically hide behind real-world objects like trees – and revealed the acquisition of a 3D spatial mapping company called 6D.ai.

This shows that next-gen AR gaming won’t necessarily be tied to Apple’s LiDAR-based tech or ARKit platform, but the iPhone 12 should at least give you a ringside seat for watching the AR battle play out.

But what about non-gaming experiences for the LiDAR sensor? So far, the most polished seem to be based around interior design. For example, the IKEA Place app lets you move around virtual furniture in your living room, like you’re in a real-life version of The Sims.

But while the iPad Pro 2020’s improved AR placement and occlusion (or ability to hide virtual objects behind real ones) are helpful, it’s still not a scintillating new use for the LiDAR scanner.

Still, while the tech is currently more useful for CAD designers and healthcare professionals (if you have an iPad Pro, check out the impressive Complete Anatomy app), there is still plenty of room for creativity and surprises to appear in the next year.

As Halide’s proof-of-concept app Esper shows, the LiDAR sensor could help app developers invent new creative forms that go way beyond traditional photography and video.

In the meantime, it’s fair to say that the LiDAR scanner on the iPad Pro and possibly iPhone 12 will initially be there to wow developers rather than tech fans.

You’ll get the chance to test-drive the future on LiDAR-equipped devices – but the real leap should come when these sensors and apps arrive on the Apple Glasses.

Google has launched its next generation of Pixel phones, setting the stage for a head-to-head competition with Apple as both tech giants aim to integrate more advanced artificial intelligence (AI) features into their flagship devices. The unveiling took place near Google’s Mountain View headquarters, marking an early debut for the Pixel 9 lineup, which is designed to showcase the latest advancements in AI technology.

The Pixel 9 series, although a minor player in global smartphone sales, is a crucial platform for Google to demonstrate the cutting-edge capabilities of its Android operating system. With AI at the core of its strategy, Google is positioning the Pixel 9 phones as vessels for the transformative potential of AI, a trend that is expected to revolutionize the way people interact with technology.

Rick Osterloh, Google’s senior vice president overseeing the Pixel phones, emphasized the company’s commitment to AI, stating, “We are obsessed with the idea that AI can make life easier and more productive for people.” This echoes the narrative Apple is likely to push when it unveils its iPhone 16, which is also expected to feature advanced AI capabilities.

The Pixel 9 lineup will be the first to fully integrate Google’s Gemini AI technology, designed to enhance user experience through more natural, conversational interactions. The Gemini assistant, which features 10 different human-like voices, can perform a wide array of tasks, particularly if users allow access to their emails and documents.

In an on-stage demonstration, the Gemini assistant showcased its ability to generate creative ideas and even analyze images, although it did experience some hiccups when asked to identify a concert poster for singer Sabrina Carpenter.

To support these AI-driven features, Google has equipped the Pixel 9 with a special chip that enables many AI processes to be handled directly on the device. This not only improves performance but also enhances user privacy and security by reducing the need to send data to remote servers.

Google’s aggressive push into AI with the Pixel 9 comes as Apple prepares to unveil its iPhone 16, which is expected to feature its own AI advancements. However, Google’s decision to offer a one-year free subscription to its advanced Gemini Assistant, valued at $240, may pressure Apple to reconsider any plans to charge for its AI services.

The standard Pixel 9 will be priced at $800, a $100 increase from last year, while the Pixel 9 Pro will range between $1,000 and $1,100, depending on the model. Google also announced the next iteration of its foldable Pixel phone, priced at $1,800.

In addition to the new Pixel phones, Google also revealed updates to its Pixel Watch and wireless earbuds, directly challenging Apple’s dominance in the wearable tech market. These products, like the Pixel 9, are designed to integrate seamlessly with Google’s AI-driven ecosystem.

Google’s event took place against the backdrop of a significant legal challenge, with a judge recently ruling that its search engine constitutes an illegal monopoly. This ruling could lead to further court proceedings that may force Google to make significant changes to its business practices, potentially impacting its Android software or other key components of its $2 trillion empire.

Despite these legal hurdles, Google is pressing forward with its vision of an AI-powered future, using its latest devices to showcase what it believes will be the next big leap in technology. As the battle for AI supremacy heats up, consumers can expect both Google and Apple to push the boundaries of what their devices can do, making the choice between them more compelling than ever.
