On the morning of August 8th, Beijing time, many iPhone X users said that they didn‘t want to use the original Touch ID after experiencing Face ID, and couldn‘t wait to have the Face ID function on other devices.
It is more likely that the new iPad Pro launched this year may be equipped with a Face ID. And a patent that was just awarded today shows that the same technology may appear on the Mac someday.
The first Apple patent application for facial recognition on the Mac was actually earlier than the iPhone X. It describes a very clever way to allow Macs to automatically log in to users, even in sleep mode, as long as the user is close to the computer, they can automatically log in.
“The patent describes how a Mac in sleep mode can scan the face using a camera on the computer. This may be a new feature of Power Nap. Under Power Nap, the sleeping computer can still perform some background processes but not Will consume too much power.
If the user’s Mac computer finds a human face, it will use facial recognition to wake up the computer. If the user’s authentication is passed, basically, the Mac can easily accomplish this task in sleep mode – just confirm whether it is within the camera range. A human face appears – then enters a higher power mode to perform partial facial recognition before completely waking up the machine. ”
Face detection is almost a matter of course in the patents that have just passed today.
“Another example is that the computer may apply a face detection algorithm in step 92 to detect the subject‘s facial depth map.”
Most of the face detection can be found in the previous Apple patent: using gestures to control the Mac. The inventor mentioned in the patent came from PrimeSense, a company that developed Microsoft Kinect sensors, which Apple acquired in 2013.
“Processing depth of field maps can segment and identify objects in the scene. Identifying humanoid shapes in the depth of field map (ie, structures that resemble human 3D shapes) and the changes between these shapes between scenes can be used as a way to control computer programs. .”
The patent is more extensive and seems to indicate that a wider range of body language (such as the head, torso, and arms) can be used to signal intent to the Mac. However, the focus of the patent is on the mechanism for creating depth of field maps, so there is not much clue as to how Apple will use this information.
