A new U.S. Patent (No. 5,717,392) was granted to Martin Eldridge for an information delivery device entitled "Position Responsive, Hierarchically-Selectable Information Presentation System and Control Program”. A more commercially viable title is: "GPS Tour Guide". The following is a brief description of the functional attributes of the system.

The "GPS Tour Guide", as it has been conceived, is a device that would enable a user in transit (traveling along a highway, touring a city or national park, or even visiting a museum), to effortlessly access an array of prerecorded information, delivered in a narrative account, that would describe the sights and features of the user's locality in lesser or greater detail as the user travels.

Utilizing the high-resolution signal of the Global Positioning Satellites, or technologies of any coordinate generating system, the GPS Tour Guide responds to coordinate grids to activate its own delivery system.

The delivery system and information files are organized in a hierarchical scheme of stratified layers or levels, (a unique feature of GPS Tour Guide). And these levels of information are transmitted to the user in a sequence that is dependent on (and appropriate to) the duration of the user's position within a given sector.
