For Apple, iPhone X is a revolutionary cellphone. Except the full screen design, the most revolutionary one is the Face ID. As the cellphone is not yet for sale, people are worrying about the face recognition, and start saying something bad.
Actually, Apple has already fully prepared for the worries of Face ID. They insist that people will worry about the new functions, and that the worries will be wiped out after they have experienced the new functions. The official also says that your face ID information is all stored in the cellphone itself, and it won’t be revealed to others.
It is worth noticing that the Face ID is rapid and accurate, which owes to the 3D lens. It is made by PrimeSense, who made the design of Kinect hardware in Micorsoft before Apple acquire it in 2013. Then you can regard the 3D lens and its face ID function as a new Kinect (they are both based on the infrared ray detection.)
Of course, different from the original Kinect, Apple’s face ID mainly depends on the lens and sensor to scan the face information and judge different scenes. Aplle also insist on the conference that the front lens and sensor will scan 30 thousand different point, and then form a complete dynamic 3D network of the user’ face. And this is also its strong point.
Apple is never the best inventor of technique but they indeed is the best combinatory for techniques. They will have proper new software as long as they have hardware. They are always good at this tiny creativity.
