Abstract

A region having coded data thereon, a method of applying the coded data to the region and a system having a computer system and sensing device for interacting with the region are provided. At least some of the coded data has data indicative of a functional attribute of a part of the region and the coded data has a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions. Each mark has a minimum radius and a maximum radius, where the length of a mark'"'"'s minimum radius is greater than 40% of the length of that mark'"'"'s maximum radius.

Claims

1. A region having coded data thereon, at least some of the coded data including data indicative of a functional attribute of a part of the region and the coded data comprising a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions,

wherein each mark has a minimum radius and a maximum radius, the length of a mark'"'"'s minimum radius being greater than 40% of the length of that mark'"'"'s maximum radius.

2. The region according to claim 1, wherein each mark represents one of a plurality of coded values.

3. The region according to claim 2, wherein the coded value represented by a mark is at least partially determined by the position of the mark relative to the set of predetermined nominal mark positions.

4. The region according to claim 1, wherein the predetermined nominal mark positions are arranged relative to a plurality of nominal lines.

5. The region according to claim 4 wherein at least one pair of the lines are spaced apart from one another by a distance of less than 100 millimeters.

6. The region according to claim 1, wherein the marks have centers and wherein the relative spacing of the centers of at least one pair of adjacent marks is less than 12 millimeters.

7. The region according to claim 1, wherein any 10 millimeter diameter area of the coded data indicative of the functional attribute of a part of the region includes sufficient information to identify the functional attribute.

8. A method of coding a region including applying coded data to a least a part of the region, the coded data being indicative of a functional attribute of a part of the region and comprising a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions,

wherein each mark has a minimum radius and a maximum radius, the length of a mark'"'"'s minimum radius being greater than 40% of the length of that mark'"'"'s maximum radius.

9. The method according to claim 8, wherein each mark represents one of a plurality of coded values.

10. The method according to claim 9, wherein the coded value represented by a mark is at least partially determined by the position of the mark relative to the set of predetermined nominal mark positions.

11. The method according to claim 8, wherein the predetermined nominal mark positions are arranged relative to a plurality of nominal lines.

12. The method according to claim 11, wherein at least one pair of the lines are spaced apart from one another by a distance of less than 100 millimeters.

13. The method according to claim 8, wherein the marks have centers and wherein the relative spacing of the centers of at least one pair of adjacent marks is less than 12 millimeters.

14. The method according to claim 8, wherein any 10 millimeter diameter area of the coded data indicative of the functional attribute of a part of the region includes sufficient information to identify the functional attribute.

15. A system including:

computer system, and

a sensing device for use with a region having coded data thereon, the coded data comprising a plurality of substantially undifferentiated marks positioned relative to a set of predetermined nominal mark positions and at least some of the coded data including data indicative of a functional attribute of a part of the region, each mark having a minimum radius and a maximum radius, the length of a mark'"'"'s minimum radius being greater than 40% of the length of that mark'"'"'s maximum radius,

the sensing device for sensing coded data indicative of a functional attribute of a part of the region and for transmitting, to the computer system, said sensed data or data based at least partially on said sensed data,

wherein the computer system executes, or commences execution of, a function related to the functional attribute of the sensed data.

16. The system of claim 15, wherein the computer system verifies that the functional attribute is consistent with an expected attribute of the respective part of the region.

17. The system according to claim 15, wherein each mark represents one of a plurality of coded values.

18. The system according to claim 17, wherein the coded value represented by a mark is at least partially determined by the position of the mark relative to the set of predetermined nominal mark positions.

19. The system according to claim 15, wherein the predetermined nominal mark positions are arranged relative to a plurality of nominal lines.

20. The system according to claim 15, wherein any 10 millimeter diameter area of the coded data indicative of the functional attribute of a part of the region includes sufficient information to identify the functional attribute.
