The face tracker tracks a single face in a scene and controls the position, scale and rotation of its children. It can also be used to drive a face mesh. You can have more than one face tracker in a scene.
You'd use a face tracker if you wanted to make another object move with or respond to a person's face. For example, if you inserted a 3D model of glasses, you'd need a face tracker to make sure that the glasses fit onto and moved with your face.
