Google Pixel 4 to come with Soli-powered Motion Sense and face unlock

On: July 30, 2019

Google had previously confirmed the presence of a square camera module on the Pixel 4. Now the search engine giant has announced new features of the device ahead of its presumed October launch. Interestingly, they are also in line with our exclusive Pixel 4 XL leak posted earlier this month in partnership with OnLeaks. 

In a YouTube video and blog post, Google revealed that Pixel 4 will feature Face unlock technology which is similar to iPhone’s advanced face recognition. Most Android devices just use the selfie camera for face unlocking. The face unlock feature on the Pixel 4 will use multiple sensors to scan a 3D map of a user’s faces using a dot projector, IR camera and flood illuminator. Google says that the face unlock works in almost any orientation – even if you’re holding it upside down – and you can use it for secure payments and app authentication too. The company also confirmed that the biometric data will be securely stored in its Titan M chip. The images used for face unlock are never saved or shared with other Google services. 

Another feature Google confirmed is ‘Motion Sense’ based on Project Soli that was announced back in 2015. It uses radar technology to detect any hand or finger movements above the device. The ‘Motion Sense’ feature will let users control basic functions on Pixel 4 like skipping songs, snoozing alarms, and silencing phone calls just by waving your hands. Google says that these capabilities are just the start and the feature will evolve in the future. Motion Sense feature will be available in select countries where Pixel is available. 

Google’s blog post also reveals that the Soli radar chipset can sense your hand reaching for the phone and turn on the face unlock sensors. If it recognizes your face, the phone will open as you pick it up. The Youtube video shot against a pitch-dark backdrop implies that the device’s face unlock and Motion Sense features could work in complete darkness. 

From the newly confirmed features, it is likely that the Pixel 4 will come with a thick top bezel for accommodating various sensors. It’s unknown whether there will be an in-display fingerprint scanner or Google could ditch it for an advanced face recognition system. Pixel 4’s new features are expected to set it apart from its competitors. The concrete launch date of Pixel 4 is still not known at the moment. But We expect Google to announce more features leading up to the October event.
