Without waiting for the release, without even a leak, Google itself has officially announced some of the next features that will be available on the iPixel 4. Google’s phone will arrive soon and the company itself has also published an official image of the device a few weeks ago. Now, we do not only have more details, but we also have a video showing facial unlocking in action.
As Google has published in its official blog, the Pixel 4 (expected in October this year) will feature facial unlocking and face recognition instead of the fingerprint sensor. This new 3D recognition sensor will not only be used for the face, but it will also be used to detect hand gestures. In the video, we see for example how a hand gesture is used in the air to change songs in the music player.
Project Soli: 3D recognition and a facial unlocking
The technology that makes facial recognition and gesture detection possible are called Project Soli. Google has explained that they have been developing this technology for the past five years. A small radar sensor at the top of the screen detects the movements that are generated around it and combines them with “unique software algorithms” to recognize gestures and detect when the user is nearby. Pixel 4 is going to be the first device that uses this technology from Project Soli and does it with the help of Motion Sense, the function that allows you to change songs with gestures, silence calls and more.
This sensor will also be used to introduce facial unblocking in Pixels by 3D face scanning. Google indicates that unlike other manufacturers, its new technology will not require having the phone completely in front, but will be able to detect the face from very different angles. Neither is it affected by the orientation of the phone, for example, we can unlock the device with your face even if it faces down, as they have commented.
Hardware security, several rear cameras and more innovations of the Pixel 4
Another aspect that the brand has wanted to highlight is that of security, the Pixel 4 processes the information collected by local facial recognition. That is, the data is not sent to the Google cloud or to any of your servers to perform this task, unlike other more advanced tasks of its services. As we have seen in other products from Google, Pixel 4 will have the security chip and dedicated Titan M.
What the Pixel 4 says goodbye is from the notch, Google has preferred to include a thicker frame at the top and fill it with all kinds of sensors. In the image they have shown we see the following from left to right: infrared camera for facial unlocking, front camera, light sensor, audio port, Soli radar chip, dot projector for facial unlocking, another infrared camera for unlocking facial, face illuminator for facial unlocking.
Additionally, in the middle of last month, Google officially confirmed the appearance of the Pixel 4. In the image they showed us, we could see a square module with several rear cameras (two next to the proximity sensor and the flash). Google Pixels have always been characterized by trusting on a single lens and that the software is responsible for processing the images. Pixel 4 will say goodbye to this philosophy and will also include more lenses.
