Google recently announced Apple’s FaceID like biometric face-unlock on the upcoming Google Pixel 4. This is not a simple camera-based face unlock as far as we know. It will be made possible using an array of complicated infra-red sensors and camera sensors so it will also work flawlessly at night. Now we have reason to believe that the upcoming Pixelbook 2 might also feature the same face unlock system.
Chrome Unboxed recently discovered mention of Face Detection in an update to the Chromium open-source project. Google Chrome and ChromeOS are based on the Chromium open-source project and ChromOS is what powers Chromebooks and the Pixelbook.
The support of this face unlock feature on older hardware is also expected. It is expected that older Chromebooks and Pixelbooks will support the new face unlock feature but using just simple camera sensors available in the devices. Since there is the lack of an infra-red sensor, using face unlock in poor lighting conditions would most likely not work. It is also being reported that on these older devices, you have to log in using your password when booting up, and the face unlock feature will only be available for the rest of that session. So you will have to enter your password each time you boot up your Chromebook.
Although there isn’t any solid evidence pointing out that the face-unlock features will be available on the upcoming Pixelbooks, these code commits clearly indicate that the feature is soon to be available.
FROMLIST: dts: arm64: mt8183: Add FD nodes
This patch adds nodes for Face Detection (FD) unit. FD is embedded in Mediatek SoCs and works with the co-processor to perform face detection on the input data and image and output detected face result.
Looking at the code commit above we can be somewhat certain that the ChromeOS will soon support face-unlock. Google also teased new ways of interacting with your phone without actually touching it in this Youtube video
