1. A method for generating audible feedback, the method comprising: (a) creating a computer-generated reconstruction of an overall volume, the computer-generated reconstruction identifying at least one feature of interest within the overall volume; (b) creating a computer-generated real-time image of the overall volume, the computer-generated real-time image further including at least one trackable point, the at least one trackable point movable in real-time with respect to the overall volume; (c) causing a computer to overlay the computer-generated real-time image and the computer-generated reconstruction with substantial spatial identity and substantial spatial fidelity; (d) causing the computer to track the at least one trackable point with substantial positional fidelity to the computer-generated real-time image; and (e) creating computer-generated audible feedback, the computer-generated audible feedback describing movement of the at least one trackable point with respect to the at least one feature of interest.
