Abstract
A navigation device displays major routes and direction indications without a specific destination requirement. Where several possible destinations are presented, the device displays information for a destination at or when nearing decision points for traveling to the destination. Direction indicators can be presented on top of an appropriately scaled map having routes displayed which are integral to the indicators and directions. A destination displayed may be selected to retrieve detailed driving instructions to that specific destination. In one embodiment, the navigation device displays direction indications to major destinations, entrances, exits, and other important facilities in a “highway sign” fashion at major decision points.
Claims134
A method, comprising the steps of:
- receiving information indicating an origin;
- determining a set of at least one general destination without receiving an indication of a specific destination;
- computing directional information between said origin and each general destination;
- and
- reporting said directional information.
One or more processor readable storage devices having processor readable code embodied on said processor readable storage devices, said processor readable code for programming a processor to perform a method comprising the steps of:
- receiving information indicating an origin;
- determining a set of at least one destination without receiving an indication of a specific destination;
- computing directional information between said origin and each destination;
- and
- reporting said directional information.
An apparatus for providing direction information, comprising:
- an origin locator configured to determine a location of an origin;
- a destination mechanism configured to determine a set of at least one destination without information regarding any specific destination;
- a directions finding device configured to compute directional information from said origin to each of said destinations;
- and
- a report mechanism configured to report the directional information computed.
A method, comprising the steps of:
- receiving information indicating a destination;
- determining a set of two or more possible origins without receiving an indication of a specific origin;
- computing directional information between said destination and each possible origin;
- and
- reporting said directional information.
