Abstract

A computer system for interactively inputting parameter values. The computer system with a screen, memory and a set of parameters, comprises an interactive input field each for each of said set of parameters, a set of information items each for each of said set of parameters, said set of information items being stored in the memory; and a set of virtual keys stored in the memory. On selecting a parameter displayed on the screen, an interactive input field associated with the selected parameter and a subset of virtual keys is displayed on the screen. The subset of virtual keys comprises only those keys that are relevant to changing a value of the selected parameter.

Claims

1. A computer system with a screen, memory and a set of parameters, said system comprising:

an interactive input field for at least one parameter of said set of parameters; and

a set of virtual keys stored in the memory,

wherein, on selecting said at least one parameter displayed on the screen, the interactive input field associated with the selected parameter and a subset of virtual keys is displayed on the screen, and

wherein the subset of virtual keys is created dynamically based on said selected parameter.

2. The computer system of claim 1, wherein the computer system is a palm-held computer.

3. The computer system of claim 1, wherein said subset of keys comprises only those keys that are relevant to changing a value of the selected parameter.

4. The computer system of claim 1, wherein the displayed subset of virtual keys does not overlay the displayed interactive input field.

5. The computer system of claim 1, further comprising a set of information items for said at least one parameter, said set of information items being stored in the memory, wherein the set of information items comprises parameter name, parameter type, and limit values for the parameter.

6. The computer system of claim 1, wherein said system further comprises an interactive input field each for each of said set of parameters and a set of information items each for each of said set of parameters.

7. The computer system of claim 5, wherein the set of information items further comprises help information associated with the parameter.

8. The computer system of claim 7, wherein the help information is a help information in a Windows 95®

format.

9. The computer system of claim 5, wherein an error message is displayed when a user enters a value for the parameter that is outside of the limit values for the parameter.

10. A computer system comprising a palm-held computer including a touch-sensitive screen and a memory, said memory comprising instructions, said instructions enabling the computer to enable a user to select a parameter by touching the touch-sensitive screen, said instructions further enabling the computer to display a subset of virtual keys that are dynamically created based on the parameter, and said subset of virtual keys being sufficient to change the value of the parameter.

11. The computer system of claim 10 wherein said instructions further enable the computer to monitor whether a value entered by the user is within a preset range of values for the selected parameter.

12. The computer system of claim 10 wherein said instructions further enable the computer to display help information for the selected parameter on indication by the user.

13. A method of inputting values for a parameter into a computer system comprising:

(a) selecting the displayed parameter on a screen;

(b) displaying a dialog including an interactive input field associated with the parameter on the screen;

(c) displaying a subset of virtual keys on the screen; and

(d) using the subset of virtual keys to input values for the parameter,

wherein the subset of virtual keys is created dynamically based on said selected parameter.

14. The method of claim 13 wherein the displayed subset of virtual keys does not overlay the interactive input field.

15. The method of claim 13 wherein the subset of virtual keys comprises only those keys that are relevant to changing the value of the parameter.

16. The method of claim 13 wherein the displayed parameter is associated with a set of information items comprising parameter name, parameter type and limit values for the parameter.

17. The method of claim 16 wherein the set of information items further comprises help information.

18. The method of claim 13 wherein an interactive input field each is associated with each of said set of parameters and a set of information items each is associated with each of said set of parameters.

19. The method of claim 13 further comprising

(e) displaying an error message on entry of a value outside the limit values for the parameter.

20. The method of claim 17 wherein the help information associated with the parameter is displayed using a Windows 95®

help format.

21. A computer program product, including a computer readable medium comprising instructions, said instructions comprising:

a selector code to enable a user to select a parameter displayed on a screen;

a dialog code to display a dialog associated with the parameter on the screen;

a keyboard code to display a subset of virtual keys on the screen; and

a data receiving code, to enable a user to input parameter values using the subset of virtual keys,

wherein, the subset of virtual keys is created dynamically based on the selected parameter.

22. The computer program product of claim 21, wherein the displayed subset of virtual keys does not overlay an interactive input field associated with the parameter.

23. The computer program product of claim 21, wherein said subset of virtual keys comprises only those keys that are relevant to changing the value of the parameter.

24. The computer program product of claim 21, further comprising an information code to store information associated with the parameter, said information comprises parameter name, parameter type and limit values of the parameter.

25. The computer program product of claim 24, wherein said information further comprises help information.

26. The computer program product of claim 24, further comprising an error message code to display an error message on entry of a value outside the limit values for the parameter.

27. The computer program product of claim 25, wherein the help information is displayed using a Windows 95®

format.
