Abstract

In accordance with one embodiment, a navigation system includes a display device configured to detect user gestures, a data storage device including program instructions stored therein, a map stored within the data storage device, and a controller operatively coupled to the data storage device and the display device and configured to execute the program instructions to receive first user gesture data associated with a first portion of a first user gesture from the display device, generate a first predicted user gesture data based upon the stored map and the first user gesture data, and control the display device to render the first predicted user gesture data as the user is continuing the first user gesture.

Claims

1. A navigation system comprising:

a display device configured to detect user gestures;

a data storage device including program instructions stored therein;

a map stored within the data storage device; and

a controller operatively coupled to the data storage device and the display device and configured to execute the program instructions to;

receive first user gesture data associated with a first portion of a first user gesture from the display device;

generate a first predicted user gesture data based upon the stored map and the first user gesture data; and

control the display device to render the first predicted user gesture data as the user is continuing the first user gesture.

2. The navigation system of claim 1, wherein the display device is configured to detect tactile user gestures.

3. The navigation system of claim 1, wherein the controller is further configured to execute the program instructions to:

generate the first predicted user gesture data by associating the first portion of the first user gesture with a geographical feature.

4. The navigation system of claim 3, wherein the first predicted user gesture data conforms to the geographical feature.

5. The navigation system of claim 4, wherein the geographical feature comprises at least one roadway.

6. The navigation system of claim 4, wherein the geographical feature comprises a geographically identifiable area.

7. The navigation system of claim 1 wherein the controller is further configured to execute the program instructions to:

receive second user gesture data associated with a second portion of the first user gesture from the display device after controlling the display device to render the first predicted user gesture data as the user is continuing the first user gesture;

generate a second predicted user gesture data based upon the stored map, the first user gesture data, and the second user gesture data; and

control the display device to render the second predicted user gesture data as the user is continuing the first user gesture.

8. The navigation system of claim 1, wherein the controller is further configured to execute the program instructions to:

identify a plurality of points of interest associated with the rendered first predicted user gesture data;

control the display device to render data associated with the identified plurality of points of interest;

receive third user gesture data associated with a second user gesture from the display device;

associate the second user gesture with one of the identified plurality of points of interest; and

modify the rendered data associated with the identified plurality of points of interest to exclude any data associated with the one of the identified plurality of points of interest.

9. The navigation system of claim 1, wherein the controller is further configured to execute the program instructions to:

receive non-user gesture modality data; and

generate the first predicted user gesture data based upon the stored map, the first user gesture data, and the non-user gesture modality data.

10. The navigation system of claim 1, wherein the controller is further configured to execute the program instructions to:

select the rendered first predicted user gesture data based upon user input; and

modify the rendered first predicted user gesture data based upon user input.

11. A navigation system comprising:

a display device configured to detect user gestures;

a data storage device including program instructions stored therein;

a map stored within the data storage device; and

a controller operatively coupled to the data storage device and the display device and configured to execute the program instructions to;

receive first user gesture data associated with a first portion of a first user gesture from the display device;

generate first predicted user gesture data based upon the stored map and the first user gesture data, wherein the first predicted user gesture data conforms to a geographical feature of the map; and

control the display device to render the first predicted user gesture data.

12. The navigation system of claim 11, wherein the controller is further configured to execute the program instructions to:

control the display device to render the first predicted user gesture data as the user is continuing the first user gesture.

13. The navigation system of claim 11, wherein the display device is configured to detect tactile user gestures.

14. The navigation system of claim 11, wherein geographical feature comprises at least one roadway.

15. The navigation system of claim 11, wherein the geographical feature comprises a geographically identifiable area.

16. The navigation system of claim 11 wherein the controller is further configured to execute the program instructions to:

receive second user gesture data associated with a second portion of the first user gesture from the display device after controlling the display device to render the first predicted user gesture data;

generate a second predicted user gesture data based upon the stored map, the first user gesture data, and the second user gesture data; and

control the display device to render the second predicted user gesture data.

17. The navigation system of claim 16, wherein the controller is further configured to execute the program instructions to control the display device to render the second predicted user gesture data as the user is continuing the first user gesture.

18. The navigation system of claim 11, wherein the controller is further configured to execute the program instructions to:

identify a plurality of points of interest associated with the rendered first predicted user gesture data;

control the display device to render data associated with the identified plurality of points of interest;

receive third user gesture data associated with a second user gesture from the display device;

associate the second user gesture with one of the identified plurality of points of interest; and

modify the rendered data associated with the identified plurality of points of interest to exclude any data associated with the one of the identified plurality of points of interest.

19. The navigation system of claim 11, wherein the controller is further configured to execute the program instructions to:

receive non-user gesture modality data; and

generate the first predicted user gesture data based upon the stored map, the first user gesture data, and the non-user gesture modality data.

20. The navigation system of claim 11, wherein the controller is further configured to execute the program instructions to:

select the rendered first predicted user gesture data based upon user input; and

modify the rendered first predicted user gesture data based upon user input.
