Abstract

A wireless portable device that includes a screen, a wireless antenna, transmitter and receiver for communicating over a wireless network with a remote server, a GPS antenna and receiver for receiving GPS signals from GPS satellites, a processor controlling communication over the wireless network and processing the GPS signals, memory storing a navigator application that utilizes the GPS signals and a client program. The client program includes a hypertext markup language (HTML) or scripting language interpreter that is configured to receive a file including hyperlinks from a server, render the file on the screen of the wireless portable device, recognize tags associated with a hyperlink, including either location information, geocode or both, and use the tags to initiate the navigator application.

Claims

1. A wireless portable device, comprising:

a screen;

a wireless transceiver for communicating over a wireless network with a remote server and receiving a file from the server;

a GPS receiver for receiving GPS signals from GPS satellites;

a processor connected to the wireless transceiver for controlling communication over the wireless network and connected to the GPS receiver;

memory storing software that renders the file on the screen and utilizes a tag embedded in the file along with location information based on the received GPS signals to provide navigation features.

2. The wireless portable device of claim 1, wherein the tag specifics a location.

3. The wireless portable device of claim 2, wherein the software provides a choice of routes to the location.

4. The wireless portable device of claim 2, wherein the software provides a route to the location.

5. The wireless portable device of claim 4, wherein the route is calculated by the processor.

6. The wireless portable device of claim 4, wherein the route is calculated by a GPS server located remotely from the device.

7. The wireless portable device of claim 6, wherein location information embedded in the tag and the device'"'"'s current location, as determined from the received GPS signals, are sent to the GPS server through the wireless transceiver and the route is received from the GPS server through the wireless transceiver.

8. The wireless portable device of claim 1, wherein the software is configured to recognize latitude and longitude information embedded in the tag, and further configured to use the latitude and longitude information to locate a point of interest.

9. The wireless portable device of claim 1, wherein the software is configured to recognize location information embedded in the tag, and, when a user clicks on a corresponding link, to perform on-demand geocoding in accordance with the embedded location information.

10. The wireless portable device of claim 9, wherein the software is configured to prompt the user in the event the embedded location information is ambiguous.

11. The wireless portable device of claim 10, wherein the software is configured to present a list of possible matches as options when prompting the user.

12. The wireless portable device of claim 1, wherein the page displayed on the screen includes a link associated with the tag and the software is configured to recognize location information embedded in the tag.

13. The wireless portable device of claim 12, wherein the software provides a route to a location specified in the tag when a user selects the link.

14. The wireless portable device of claim 12, wherein the software provides a choice of routes to a location specified in the tag when a user selects the link.

15. A wireless portable device, comprising:

a screen;

a wireless transceiver for communicating over a wireless network with a remote server and receiving a file from the server;

a GPS receiver for receiving GPS signals from GPS satellites;

a processor connected to the wireless transceiver for controlling communication over the wireless network and connected to the GPS receiver;

memory storing software that renders the file on the screen and utilizes a tag embedded in the file along with location information based on the received GPS signals to provide a route from a current location to a location specified by the tag.

16. The wireless portable device of claim 15, wherein the route is calculated by a GPS server located remotely from the device.

17. The wireless portable device of claim 15, wherein the page displayed on the screen includes a link associated with the tag and the software is configured to recognize location information embedded in the tag.

18. The wireless portable device of claim 15, wherein the software follows the route to the location specified by the tag by displaying the route on the screen and updating the displayed route as the device traverses the route.
