Brief description
To move through memories, the player must "calibrate your eyes", which requires you to position your head within a boxed area of the screen/webcam and blink slowly to make sure the camera registers the blinks. Then the player is prompted to blink and see if it's registered. Some memories will stop before you want them to because you blink. Other times, you have to keep your eyes closed to hear what's being said on the other side of a door.
