ABSTRACT:
REFERENCE TO RELATED APPLICATIONS
The present application is related to the copending application entitled “METHOD AND SYSTEM FOR FORMING A KEYWORD DATABASE FOR REFERENCING PHYSICAL LOCATIONS”, Ser. No. 09/586,206, and the copending application entitled “METHOD AND SYSTEM FOR USING KEYWORDS TO SPECIFY LOCATIONS FOR NAVIGATION- AND MAP-RELATED SERVICES”, Ser. No. 09/586,320, both filed on even date herewith, the entire disclosures of which are incorporated by reference herein.
BACKGROUND OF THE INVENTION
The present invention relates to systems that provide users with navigation-related or map-related features and services and more particularly the present invention relates to an innovation that facilitates the specification of physical locations when using systems that provide such features or services to users.
Various technologies have been developed that provide navigation-related and map-related services. For example, vehicle navigation systems can determine where a vehicle is located and also can provide directions to travel to a desired destination. Also, Internet sites are available that provide maps, directions for traveling to a desired destination from a specified starting point, and other map- or navigation-related services. Further, hand-held devices are available that can determine one's position and a map of one's surroundings.
Despite the various navigation-related and map-related technologies that exist, there continues to be room for improvement. One area in which there is room for improvement relates to designating a physical location when using a navigation-related or map-related device, service, or technology.
For example, when using a navigation system, Internet mapping service, or other system or service, a user often needs to specify a physical location. For example, to obtain route guidance for traveling to a destination, a user is required to specify a physical location as the desired destination. Conventional navigation systems, Internet mapping services, and the like, may provide a means by which a user can input a street, street address, cross street, or location name (e.g., O'Hare Airport) in order to specify a physical location. Although specifying a physical location in this manner works well, difficulties can occasionally arise. For example, addresses may be unknown or difficult to remember. Also, addresses can sometimes be awkward to input into a navigation system. Furthermore, relatively few locations have names by which they are known. Even further, not all points of interest may be included in the database used by the navigation system or mapping service.
Another consideration that relates to the use of address information to specify a physical location is that address information is not available for all regions. Accurate address information can be difficult to collect and maintain. Address schemes that exist in different countries, or even within the same country, are complex and inconsistent, making it difficult to create and use products for computer-assisted navigation- and map-related services. Even when address information is available, the information is not always up-to-date.
Accordingly, there is a need for a way to facilitate the specification of a physical location when obtaining navigation-related or map-related features from a computer-based system that provides such features.
SUMMARY OF THE INVENTION
To address these and other objectives, the present invention comprises an improved method and system for specifying physical locations when using applications run on navigation systems or other computer platforms that provide navigation- or map-related functions. When requesting a navigation- or map-related function from such an application, a user specifies a physical location using a keyword instead of specifying the physical location conventionally, such as by street address. A keyword database relates keywords to physical locations. The application uses the keyword database, or a copy thereof, to find data indicating the physical location associated with the keyword specified by the user. Preferably, physical locations are defined in the keyword database in terms of data in a corresponding geographic database. The application then performs the requested navigation- or map-related function using the data indicating the physical location associated with the keyword.
The keyword database is built using input from users. An on-line system is provided that users can access to associate keywords with physical locations. A user accessing the on-line system is presented with a map from which a physical location can be selected. A keyword, which may be selected by the user, is associated with the selected physical location. The keyword is stored in the keyword database along with data indicating the associated physical location.
