Abstract:
1. A computer implemented method for selecting a navigational waypoint for use, the method comprising: receiving a partially entered waypoint identifier identifying, in part, a navigational waypoint for use; searching for the navigational waypoint for use from amongst a plurality of waypoint identifiers using the partially entered waypoint identifier and a search criterion other than a criterion based on a pre-existing ordering of the plurality of waypoint identifiers; and completing the partially entered waypoint identifier based on results from the searching, the completed waypoint identifier forming a user-selectable navigational waypoint for use; wherein searching includes: (i) searching for the navigational waypoint for use using as the search criterion a geographical relationship between a location of each waypoint identifier of the plurality of waypoint identifiers and a reference location; and (ii) returning as the result of the searching, a first waypoint identifier, in an event the geographical relationship is that the distance between the location of the first waypoint identifier and the reference location is within a vicinity term, and returning at least a second waypoint identifier, in an event the geographical relationship is that the distance between the location of the second waypoint identifier and the reference location is within the vicinity term.
