Google confirms the Pixel 4 supports face unlock and motion gestures

Google has just confirmed two new features of the Pixel 4 smartphone.

In a blog post and YouTube clip, Google revealed that the Pixel 4 will use a motion-sensing radar technology (Soli) to detect small motions around the phone.

When combined with unique software algorithms and advanced hardware sensor, the Pixel 4 are able to recognise gestures and detect when the user is nearby.

Soli will enable some Motion Sense features such as skipping songs, snoozing of alarms and silencing incoming calls with just a wave of your hand.

Motion Sense will be available in selected markets.

Similar to Face ID on the iPhone X series, the Pixel 4 will also have face unlocking technology powered by Soli, and will excel in some ways. For example, Soli will proactively turn on its face unlock sensors as the user reaches for the phone.

If the face unlock sensors and algorithms recognise the user, the phone will be unlocked while it is being picked up. It also works in almost any orientation, supports secure payments and app authentication.

Google claims that the face unlock uses facial recognition technology that is processed on the Pixel 4, and information captured from face unlock is never saved or shared with other Google services.

Also, the face data is stored securely in the Pixel's Titan M security chip.
