Traduction de l’étape 14
Here's the phone in action. The first blinky dot you see is the proximity sensor trying to figure out if there's anything in front of the phone.
We click the power button and the IR projectors go to work. Notice that the 3D effect of the background is intermittent.
That's because the system only renders the 3D effect when it finds a face, it stops once it loses facial recognition. This helps the Fire Phone minimize its battery consumption.
