Abstract

A method of processing a transaction comprising the steps of generating a position signal indicative of position of a touching of a touch screen having a transparent reference surface, displaying an image of the touching of the screen responsive to the position signal, and changing the image as a function of the difference between the position signal and a predetermined position value.

Claims

1. A transaction terminal comprising:

a touch screen having a transparent reference surface for generating a position signal indicative of position of a touching of the screen;

a display that is under the transparent reference surface that is responsive to an input signal which creates a image on the display; and

,

a controller for capturing position signals and generating the input signal, the input signal being a function of the captured position signals and a predetermined position value signal that is indicative of a predetermined position where a person is expected to sign on the display and generating an offset correction value to cause a displayed signature to migrate closer to the predetermined position,

wherein the image changes position on the display during the capture of the position signals.

2. A transaction terminal in accordance with claim 1, wherein the predetermined position value is a function of a nominal signature characteristic determined from a sample of signatures.

3. A transaction terminal in accordance with claim 2, wherein the sample of signatures is at least 10 signatures.

4. A transaction terminal in accordance with claim 2, wherein the function is a summation function.

5. A transaction terminal in accordance with claim 1, wherein the predetermined position value signal is a function of a position of a designated signature placement element.

6. A transaction terminal in accordance with claim 1, wherein there is an offset between a position signal and a corresponding part of the image on the display such that the offset correction value is determined by as a function of the predetermined position value adjusted by the maxima average peak and minima average peak of the generated position signals.

7. A transaction terminal in accordance with claim 1, wherein the image changes position iteratively as the signature is made.

8. A transaction terminal in accordance with claim 1, wherein the controller changes the position of the image incrementally.

9. A transaction terminal in accordance with claim 1, wherein the transaction terminal is a point of sale terminal.

10. A transaction terminal in accordance with claim 1, wherein the touching is performed with a stylus.

11. A method of processing a transaction comprising the steps of:

generating a position signal indicative of position of a touching of a touch screen having a transparent reference surface;

displaying an image of the touching of the screen responsive to a function of the position signal; and

,

capturing position signals and generating an input signal, the input signal being a function of the captured position signals and a position value signal indicative of a predetermined position where a person is expected to sign on the display and generating an offset correction value to cause a displayed signature to migrate closer to the predetermined position,

wherein the image changes position on the display during the capture of the position signals.

12. A method of processing a transaction in accordance with claim 11, wherein the predetermined position value is a function of a nominal signature range midpoint determined from a sample of signatures.

13. A transaction terminal in accordance with claim 12, wherein the sample of signatures is at least 10 signatures.

14. A transaction terminal in accordance with claim 11, wherein the predetermined position value is a function of a designated signature line.

15. A transaction terminal in accordance with claim 11, wherein the offset correction value is determined by as a function of the predetermined position value adjusted by the maxima average peak and minima average peak of the generated position signals.

16. A transaction terminal in accordance with claim 11, wherein the function is performed iteratively as the signature is made.

17. A transaction terminal in accordance with claim 11, wherein the controller changes the position of the image incrementally.

18. A transaction terminal in accordance with claim 11, wherein the transaction terminal is a point of sale terminal.

19. A transaction terminal in accordance with claim 11, wherein the touching is performed with a stylus.

20. A transaction terminal in accordance with claim 11, wherein the difference is a summation function.

21. A method of processing a transaction comprising the steps of:

activating a display to present an image on the display to assist a person to sign the display;

displaying a virtual signature placement element at a predetermined position where a person is expected to sign the display;

manually moving a stylus in a cursive manner corresponding to the writing of the person'"'"'s signature;

sensing a series of positions of the stylus and generating a series of corresponding position coordinates;

creating a digital record of the signature by storing the coordinates in memory;

causing the display to display an image of the signature concomitantly with movement of the stylus;

changing the position of the image of the signature as a function of the difference between the series of corresponding position coordinates and the predetermined position value during the capture of the signature.

22. A method in accordance with claim 21, wherein the predetermined position value is representative of average signature coordinates used by signatories.

23. A method in accordance with claim 21, wherein the predetermined position value is derived from the average coordinates for a characteristic of each particular customer name.

24. A method in accordance with claim 21, wherein the position of the image is changed incrementally.

25. A method in accordance with claim 21, wherein the position of the image is changed in two directions.

26. A transaction terminal comprising:

a touch screen having a transparent reference surface for generating a position signal indicative of position of a touching of the screen;

a display that is under the transparent reference surface that is responsive to an input signal which creates a image on the display; and

,

a controller for capturing position signals and generating the input signal, the input signal being a function of the captured position signals and a predetermined position signal where a person is expected to sign on the display and generating an offset correction value to cause a displayed signature to migrate closer to the predetermined position,

wherein the image changes position on the display during the capture of the position signals.

27. A method of processing a transaction comprising the steps of:

generating a position signal indicative of position of a touching of a touch screen having a transparent reference surface;

displaying an image of the touching of the screen responsive to a function of the position signal; and

,

capturing position signals and generating an input signal, the input signal being a function of the captured position value signals and a predetermined position value signal where a person is expected to sign on the display and generating an offset correction value to cause a displayed signature to migrate closer to the predetermined position,

wherein the image changes position on the display during the capture of the position signals.
