This technology will be based on Soli, a motion radar located at the top of the device’s screen Google’s next smartphone, the Pixel 4, will have a gesture control system thanks to a motion sensor located at the top of the screen, which also activates the facial recognition sensor to unlock the terminal. This has been communicated by the Silicon Valley company through its official blog.
The gesture control in Pixel 4 will be based on Soli, a motion radar located at the top of the screen, which works together with an algorithm to detect small movements around the phone. This sensor will allow users to perform actions without having to touch the device, such as silencing calls or skipping songs, although, as they point out from Google, the capabilities will improve over time.
Soli also works on the facial recognition system to unlock the device. Specifically, and as they explain from the technological point of view, what it does is activate “proactively” the facial recognition sensors and, if these sensors and the accompanying algorithm identify the user, it unlocks the Pixel 4 “in a single movement”.
In turn, the information that Soli collects is processed on the device itself and “never saved or shared with other Google services”, similar to the management of facial recognition sensors. To ensure security, Google uses the Titan M chip to protect information at the hardware level.
This is not the first time that this type of technology is used in a smartphone. Samsung has been fooling around with that idea for some time, as the One Hand Operation + app recently demonstrates, which allows you to control Korean signature devices using gestures. There are also third-party applications, such as T Swipe Gestures, that allow you to use a smartphone without interacting with the screen.
