A little way-out for Google, but this time around the tech giant has been giving tough competition to the grapevine since it has taken upon itself to leak the features of its upcoming Google Pixel 4 smartphone.

Only last month Google leaked the render of the Google Pixel 4 depicting phone’s rear panel that showed off a dual-rear-camera set up in a square layout. Also, there was no fingerprint seen at the back, prompting all of us to believe that the device will have an in-display fingering sensor instead.

But now a second video teaser released by Google suggests that the Pixel 4 will be armed with a very-secure face unlock feature, though there is no hint if the handset will also have an in-display fingerprint scanner in tow.

But the most attention-grabbing feature in the teaser is the hands-free control for the device. Google is calling it Motion Sense technology which might make the touches and swipe redundant in getting our tasks done by the phone such as muting calls, snoozing alarms or skipping songs just by waving of our hand.

This will be possible because the Google Pixel 4 will come with a Soli based chip that makes use of the radar technology. Google has been developing the Soli project since 2014 while showcased it in 2015 at Google I/O event and now a miniature version of it is going to find a place in the Google Pixel 4 for the first time.

So how does the system works? Here it is. The Soli emits electromagnetic waves in a wide direction capturing even minor movements of hands of a user. Then with the help of optimized algorithms, it deciphers the command intended by each type of hands movement. Google says the Motion Sense will get even better with time by including a wide array of gesture recognitions.

Coming back to face unlock feature, Google says it is going to be the one of most secure face unlocks because the facial recognition is processed locally on the device and the image data is never shared with Google or any third parties.

The Pixel 4 will have a Titan M security chip integrated into it along with the Soli radar chip that will store image data without transferring it to the Google server. Even the Motion Sense data won’t be shared with Google.

So, Google is giving all due importance to user’s data privacy, not to mention the Google Pixel 4 will come with Android Q out-of-the-box as well which will add extra security and privacy features for sure.

However, it is not the first time we have been hearing about the Motion Sense-like technology, The LG G8 has “Air Motion” controllers for similar kind of purposes but its implementation was tacky so the idea never took off. Even the Face unlock is much like Apple’s Face ID in iPhones.

Nevertheless, Google being itself the leaker of these two features here we may presume that the company is pretty confident of their precise implementation. Google, so far, hasn’t spilled the beans as to when the Pixel 4 line will see the daylight but considering the past record of the company we may expect it to be dropping in October this year.
