Instead of cameras, smart home tech may soon use ultrasound to detect you

Elliptic Labs, the company that helped Xiaomi’s Mi Mix enjoy a nearly bezel-less display, is taking a stab at presence detection — technology it calls Inner Peace.

It’s a direct follow-up to last year’s Inner Beauty technology, which lets smartphone manufacturers remove the proximity sensor. The technology uses the smartphone’s speaker and microphone, as well as ultrasound, to identify the gesture of moving your phone up to your face. Removal of the sensor means more space inside the device — allowing for different designs like the Xiaomi Mi Mix.

Inner Peace is based off the same technology, and Elliptic Labs is aiming it primarily at Amazon’s Echo and the Google Home ecosystem. The software can be programmed to detect if a home’s occupants aren’t moving, or it can be set up notify users of possible intruders in their home.

What’s key is that smart home devices can switch off when they do not detect someone nearby — potentially saving users some money on energy costs. Inner Peace uses ultrasound to enable a “360-degree dome field of view,” and it has no line-of-sight needs. It works in the dark as well.

The company said it’s working with manufacturers to integrate Inner Peace into products, and we can expect to see the technology in Internet of Things products by 2018. It’s unclear if it requires any hardware to work, but it’s unlikely as Inner Beauty was all software.

The company is demonstrating the technology at Mobile World Congress 2017, and we’ll update this article when we get a closer look.

Apple users are being targeted by a familiar tech support scam
Apple users face a new wave of fake iPhone and iCloud security warnings
iPhone user

AI has made online scams harder to spot by making deepfakes, voice cloning, and fake messages more realistic. Even so, the old tech support scam is still catching victims. For years, fraudsters often posed as Microsoft support workers. Now, reports suggest many are shifting their attention to Apple users.

Consumers are reporting a rise in fake “Apple High Alert” messages that claim an iPhone, iCloud account, or Apple ID has been compromised. These messages are designed to make people panic and react quickly before they can stop to check whether the warning is real.

iOS 27 puts a much better dictation experience on your iPhone, and you must enable it
A better dictation system is already on your iPhone. Apple just didn't switch it on.
Electronics, Phone, Mobile Phone

If you have an iPhone 17 Pro, iPhone 17 Pro Max, or iPhone Air running iOS 27 beta, you have a meaningfully better dictation system on your device right now. 

However, Apple did not turn it on by default, and most users have no idea it is there.

I’ve tried nearly every iOS 27 feature, and these 3 are why I’m still excited about the update
Electronics, Mobile Phone, Phone

It's been a little over a week since Apple's WWDC keynote, and the iOS 27 beta is already out in the wild. While Apple spent plenty of time talking about its Gemini-powered Siri, the thing I was most excited about was getting the update onto my iPhone 16e and seeing what it was actually like to live with.

I've been using the beta every day since then, and one thing has become pretty clear: not every new feature lived up to the hype for me. Some felt more interesting during the announcement than they do in everyday use, while others simply haven't found a place in my routine. But a few features have been the complete opposite. They're the ones I've found myself returning to again and again without even thinking about it. After spending more than a week with iOS 27, these are the three features that have stood out the most — and the biggest reason I'm still excited about this update.
