Abstract
Entering an identifier to select a navigational waypoint requires “head-down” time, resulting in less time for operating a vehicle. Accordingly, a technique for selecting a navigational waypoint for use is provided. The present invention includes receiving a partially entered identifier identifying, in part, a navigational waypoint for use, searching for the navigational waypoint for use from amongst a plurality of identifiers using the partially entered identifier and a search criterion other than a criterion based on a pre-existing ordering of the plurality of identifiers, and completing the partially entered waypoint identifier based on results from the searching. The completed waypoint identifier forms a user-selectable navigational waypoint for use. The present invention uses as a search criterion a geographical relationship between a location of each identifier of the plurality and a reference location/area to reduce the number of user-entered characters needed to select a navigational waypoint, thereby reducing “head-down” time.
