Google has just announced some features of its upcoming smartphone, the Pixel 4. The company made this announcement in a blog post, getting in front of all leaks. The Google Pixel 4 will come as the successor to the Pixel 3, not forgetting the Pixel 3 XL.
One of the features that Google announced is Motion Sense. This feature lets you control basic functions on your device just by waving your hands. The feature, which is based on Google’s Soli project, allows you to control functions such as skipping songs and snoozing alarms.
Motion Sense feature works by using a complex radar system placed above the display. This system works by detecting even the smallest of movements. Google has, however, stated that this feature will only be available in select countries where Pixel is available.
Asides from the Motion Sense feature, Google also announced the Face Unlock feature for the Pixel 4. This is reportedly not the usual facial recognition system that is found on third-party Android devices. It is actually closer to what Apple introduced with the iPhone X. This means that it will pretty much have better security than third-party Android devices.
Current Android facial recognition systems work by simply taking a picture of your face. However, the Pixel 4’s Face Unlock will work by scanning a 3D map of your face. It will achieve this by using a dot projector, IR camera, and flood illuminator. This makes it less likely for anyone to deceitfully bypass it.
Even though Google Pixel 4’s Face Unlock is similar to that of iOS, the implementation is quite different. With the aid of the Soli radar chip, the Pixel 4 will sense your hand moving towards the phone, and spring into action. If it detects your face, it will automatically unlock the phone as you are picking it up. What’s more, the Pixel 4’s Face Unlock will work in any orientation, including upside down.
We do not know if Google will still include a fingerprint sensor on the Pixel 4. It is not on the rear of the device, but it could just be under the display. However, Google may also decide to ditch the fingerprint sensor and go all-in with the Face Unlock.
Google has already revealed that the Pixel 4 will be coming later this year, but as at now, we do not know the specific date yet.
