This is a short video demonstration of the iPhone X invisible face hack created by Japanese app developer Kazuya Noshiro using the phone's facial recognition and tracking capabilities. How does it work? Simple!:
According to Noshiro's tweets,the app was made on game development platform Unity, and uses a fixed camera position to shoot a background in order to create the illusion.
So it just uses a picture of the fixed background and replaces your recognized face (sans hair, and eyes and lips) with that background. I told you it was simple. "You still don't understand it,attain you?" Of course not, attain I look like some sort of egghead? "Well your head is kind of--" You wouldn't! Hit the jump for the video.
