Google’s Pixel 4 smartphone will have motion control and face unlock

Google’s Pixel 4 is coming out later this year, and it’s getting the long reveal treatment thanks to a decision this year from Google to go ahead and spill some of the beans early, rather than saving everything for one big final unveiling closer to availability. A new video posted by Google today about the forthcoming Pixel 4 (which likely won’t actually be available until fall) shows off some features new to this generation: Motion control and face unlock.

The new “Motion Sense” feature in the Pixel 4 will detect waves of your hand and translate them into software control, including skipping songs, snoozing alarms and quieting incoming phone call alerts, with more planned features to come, according to Google. It’s based on Soli, a radar-based fine motion detection technology that Google first revealed at its I/O annual developer conference in 2016. Soli can detect very fine movements, including fingers pinched together to mimic a watch-winding motion, and it got approval from the FCC in January, hinting it would finally be arriving in production devices this year.

Pixel 4 is the first shipping device to include Soli, and Google says it’ll be available in “select Pixel countries” at launch (probably due to similar approvals requirements wherever it rolls out to consumers).

Google also teased “Face unlock,” something it has supported in Android previously – but Google is doing it very differently than it has been handled on Android in the past with the Pixel 4. Once again, Soli is part of its implementation, turning on the face unlock sensors in the device as it detects your hand reaching to pick up the device. Google says this should mean that the phone will be unlocked by the time you’re ready to use it, since it does this all on the fly, and works from pretty much any authentication.

Face unlock will be supported for authorizing payments and logging into Android apps, as well, and all of the facial recognition processing done for face unlock will occur on the device – a privacy-oriented feature that’s similar to how Apple handles its own Face ID. In fact, Google will also be storing all the facial recognition data securely in its own dedicated on-device Titan M security chip, another move similar to Apple’s own approach.

Google made the Pixel 4 official and tweeted photos (or maybe photorealistic renders) of the new smartphone back in June, bucking the trend of keeping things unconfirmed until an official reveal closer to release. Based on this update, it seems likely we can expect to learn more about the new smartphone ahead of its availability, which is probably going to happen sometime around October based on past behavior.
