Abstract

A method, apparatus and computer software for coding for tracks in a system is presented. At least one track of an object is determined on a detection display map, the track having an icon associated therewith. The icon is supplemented with a shape indicating additional information relating to attributes of the track, the shape providing perceptual visual awareness for an operator of said system. The shape includes an indicator of at least one of direction, velocity, path uncertainty, and a level of urgency of the track of the object.

First claim

What is claimed is:

1. A method of coding for tracks in a system, the method comprising: determining moving data for at least one track of a vehicle on a detection display map, the track having an icon associated therewith; supplementing the icon with a shape indicating additional information relating to attributes of the track, the shape including a fan having a plurality of arcs formed therein, any two of the arcs being spaced apart from one another by a distance that is based on at least one of the attributes of the track; and outputting the supplemented icon for presentation to an operator of the system, wherein the attributes include at least one of a path uncertainty or a level of urgency of the track.

2. The method of claim 1 wherein outputting the supplemented icon includes serially highlighting the plurality of arcs.

3. The method of claim 1 wherein a leading edge of the fan has a shape that distinguishes the icon from other icons.

4. The method of claim 3 wherein the leading edge comprises a plurality of saw tooth shapes.

5. The method of claim 1 wherein a size of the fan signifies a relative velocity of the vehicle.

6. The method of claim 1 wherein the distance is further based on a speed of the vehicle.

7. The method of claim 1 wherein a width of the fan shows a path uncertainty of the vehicle.

8. The method of claim 1 wherein a relative brightness of the icon indicates a level of urgency associated with the track.

9. A method for displaying tracks on a graphical user interface (GUI), the method comprising: displaying at least one track of a vehicle on the GUI, the track including moving data of the vehicle, and the track having an icon associated therewith; and displaying the icon with a shape indicating additional information relating to attributes of the track, the shape including a fan having a plurality of arcs formed therein, any two of the arcs being spaced apart from one another by a distance that is based on at least one of the attributes of the track, wherein the attributes include at least one of a path uncertainty or a level of urgency of the track.

10. The method of claim 9 wherein displaying the icon includes serially highlighting the plurality of arcs.

11. The method of claim 9 wherein the fan includes a leading edge having a shape that distinguishes the icon from other icons.

12. The method of claim 11 wherein the leading edge includes a plurality of saw tooth shapes.

13. The method of claim 9 wherein a size of the fan signifies a relative velocity of the vehicle.

14. The method of claim 9 wherein the distance is further based on a speed of the vehicle.

15. The method of claim 9 wherein a width of the fan is based on a path uncertainty of the vehicle.

16. The method of claim 9 wherein a relative brightness of the icon indicates a level of urgency associated with the track.

17. A non-transitory computer readable storage medium storing one or more processor-executable instructions, which when executed by at least one processor cause the at least one processor to perform the operations of: determining at least one track of a vehicle on a detection display map, the track including moving data of the vehicle, and the track having an icon associated therewith; and supplementing the icon with a shape indicating additional information relating to attributes of the track, the shape including a fan having a plurality of arcs formed therein, any two of the arcs being spaced apart from one another by a distance that is based on at least one of the attributes of the track, wherein the attributes include at least one of a path uncertainty or a level of urgency of the track.
