1. A method comprising:
scanning a focused acoustic field through space from an acoustic source until the focused acoustic field impinges upon an element of a camera with sufficient amplitude to cause vibration of the camera to a detectable level; and
estimating a relative location of the camera to the acoustic source based on the vibration of the camera.
