Google has faced all the rumors about Pixel 4 and announce some of the next features.

Motion sense

One of these new features is Motion sense. Based on Soli, the project that Google started more than four years ago, Motion Sense will allow you to control the basic functions of Pixel 4, such as skipping songs, activating alarms and silencing phone calls just by moving your hands.

  

Motion Sense works with the help of a complex radar system located above the screen that can detect even the smallest movements.

At this time, the system is only limited to recognizing simple hand gestures, but it can be configured to do more complex things in the future. Google says, however, that Motion Sense will only be available in certain countries where Pixel is available.

Face unlock

The other important feature announced today for the Pixel 4 is the face unlock.

This it's not like facial recognition that we have in the devices of third-party Android manufacturers today, or what Android itself used to have incorporated at any given time. This system is closer to the system than Apple introduced with the iPhone X in terms of complexity and, most importantly, security.

While current Android facial recognition systems only take a picture of your face, Face unlock In Pixel 4 you will scan a 3D map of your face using a spot projector, an IR camera and a floodlight and then use that information to unlock it. This is significantly safer than just an image, since it is much less likely to be falsified.

The system is virtually identical to the way it works on iOS in terms of hardware and Google also says that Save facial data securely on your Titan M chip so that no one has access to it. The difference with the Face ID is in the implementation.

While iOS requires you to unlock after the Face ID finishes scanning your face, Face Unlock on the Pixel 4 will detect that your hand moves to the phone with the Soli radar chip and then turn on the Face's unlock hardware and, If it detects your face, it will unlock the phone as you pick it up, so you will have to go directly to the home screen or wherever you left your phone. The Google system also works in any orientation, even the other way around.

We're still not sure if Google will continue to include a fingerprint sensor on the device along with the face unlock or if you will follow the path of Apple and will abandon it completely. There isn't one on the back of the phone, but there could be one under the screen. However, if we had to bet, we would say that Google could go for everyone in the face unlock feature.

Google says the Pixel 4 will arrive later this year. There is still no concrete release date, but perhaps the time in the image above is a clue.
