Navigational soundscaping

A method of presenting audio information to a user, comprising:

• determining a user location using a positioning system;
• retrieving from a memory hierarchically-organized information about a landmark based on the user location;
• and
• producing an auditory sound based on the hierarchically-organized information through one or more transducers, the auditory sound being produced so as to allow user perception of the location of the landmark relative to the user location.

An apparatus, comprising:

• means for determining a user location using a positioning system;
• means for retrieving hierarchically-organized information about a landmark based on the user location;
• and
• means for producing an auditory sound based on the hierarchically-organized information, the auditory sound being produced so as to allow user perception of the location of the landmark relative to the user location.

A computer-readable medium embodying a set of instructions executable by one or more processors, comprising:

• programming code for determining a user location using a positioning system;
• programming code for retrieving hierarchically-organized information about a landmark based on the user location;
• and
• programming code for producing an auditory sound based on the hierarchically-organized information, the auditory sound being produced so as to allow user perception of the location of the landmark relative to the user location.
