Abstract

A method and apparatus for associating components within a touch monitor comprising a monitor and a touchscreen which are interconnected with one another. A first data value is stored in a memory interconnected with the monitor, and a second data value is stored in the memory which is interconnected with the touchscreen. The first and second data values are used to identify a unique relationship between the monitor and the touchscreen. When the first and second data values are read and compared, it is determined whether the monitor and the touchscreen are associated with one another based on the first and second data values.

Claims

1. A method for associating components within a touch monitor, comprising:

storing a first data value in a memory, said memory being interconnected with a monitor; and

storing a second data value in said memory, said memory being interconnected with a touchscreen, said touchscreen and said monitor being interconnected with one another to form a touch monitor, said first and second data values identifying a unique relationship between said monitor and said touchscreen.

2. The method of claim 1, wherein said first and second data values represent one of a monitor identification number and a touchscreen identification number.

3. The method of claim 1, wherein said first and second data values represent calibration values for establishing a calibration relationship between graphic coordinates associated with said monitor and touch coordinates associated with said touchscreen.

4. The method of claim 1, further comprising:

establishing a spatial relationship between a first set of coordinates on said monitor and a second set of coordinates on said touchscreen; and

storing said spatial relationship in said memory.

5. The method of claim 1, wherein said memory includes physically separate first and second memories that are separately interconnected to said monitor and said touchscreen, respectively, said first and second memories storing said first and second data values, respectively.

6. The method of claim 1, further comprising:

reading said first and second data values with a computer interconnected with said monitor and said touchscreen;

comparing said first and second data values with said computer; and

determining when said monitor and said touchscreen are associated with one another based on said first and second data values.

7. The method of claim 1, further comprising:

selecting an updating process on a computer, said computer being interconnected with said monitor and said touchscreen;

reading and comparing said first and second data values with said updating process; and

associating said monitor and touchscreen with one another if said first and second data values are equivalent.

8. A method for automatically registering a touch monitor with an application, comprising:

connecting said touch monitor to a system computer running an application, said touch monitor including a touchscreen and a monitor;

reading a first data value from a controller module, said first data value uniquely identifying said touchscreen;

reading a second data value from said controller module, said second data value uniquely identifying said monitor;

comparing said first and second data values; and

determining whether said touchscreen and said monitor are associated with one another based on said first and second data values.

9. The method of claim 8, wherein said first and second data values represent identification data based on said monitor.

10. The method of claim 8, wherein said first and second data values are stored in extended display identification data (EDID) in separate first and second controllers, respectively, representing said controller module.

11. The method of claim 8, further comprising storing calibration data in EDID data in a first controller within said controller module, said calibration data defining a spatial relationship between said touchscreen and said monitor.

12. The method of claim 8, wherein said first and second data values being one of a monitor and a touchscreen serial number.

13. The method of claim 8, further comprising reading a third data value from one of first and second controllers within said controller module, said third data value defining a calibration relationship between said monitor and said touchscreen.

14. A touch sensitive apparatus for displaying data and accepting touch inputs, comprising:

a monitor having a display for displaying information;

a touchscreen for sensing touch events, said touchscreen being positioned proximate said display;

a first memory associated with said monitor, said first memory storing identification data; and

a second memory associated with said touchscreen, said second memory storing said identification data, said identification data being used to establish an association between said monitor and said touchscreen.

15. The apparatus of claim 14, wherein one of said first and second memories further comprising storing calibration data defining a spatial relationship between said touchscreen and said display.

16. The apparatus of claim 14, wherein said first and second memories storing EDID data, said identification data being stored as a subset of said EDID data.

17. The apparatus of claim 14, further comprising a computer for reading said identification data from said first and second memories, said computer identifying an association between said monitor and said touchscreen based on said identification data.

18. The apparatus of claim 14, further comprising a computer for reading data from said first and second memories, said data further comprising calibration data and said identification data, said computer identifying an association between said monitor and said touchscreen based on said identification data, said computer identifying a spatial relationship between said monitor and said touchscreen based on said calibration data.

19. The apparatus of claim 14, further comprising a computer for displaying a graphic having a first set of coordinates on said display, said computer accepting touch input having a second set of coordinates from said touchscreen, said computer determining a calibration value based on said first and second coordinates and saving said calibration value in one of said first and second memories.

20. The apparatus of claim 14, further comprising a second monitor having a second display for displaying data, said touchscreen being mounted proximate said second display, said second monitor having a second identification data, said second memory storing said second identification data, said second identification data being used to establish an association between said second monitor and said touchscreen, said second identification data being different with respect to said identification data.
