The true depth camera is attached on the top of the screen and it is used for facial recognition. The true depth camera cosnett of the ambient light sensor, speaker, proximity sensor, flood illuminator. Infrared camera, microphone, front camera and dot projector. Once you look at your phone the IR camera and the dot projector work together to create a mathematical model of your face. It is then compared to the face Id that was stored on your devices. “The neuron engine of the Iphones or Ipad chips combines these two elements”(McElhearn & Long, 2022). If the models are able to match up, you are able to unlock your iphone. The ambient light allows you to unlock your phone during the night. The dot projector dispatches over 30,000 invisible dots onto your face. To set up your face id you will simply have to look at the camera and move your head slowly two times. Apple will then store your data to use for future uses.
