Abstract

A help demonstration player program is provided which accepts a set of commands in the form of a script input and generates simulated keystrokes and mouse events. The keystrokes and mouse events are provided to the application program which then operates as if the user had generated the keystrokes and mouse events. The sequence of keystrokes and mouse events directs the application software to perform a task one step at a time. Since the task starts with the user'"'"'s customized screen and detects and responds to the state of the user'"'"'s desktop through the demonstration, the resulting animated display is tailored to the user'"'"'s actual display, presenting much more meaningful and less confusing instructions to the user. The demonstration player creates sample data so that the user'"'"'s actual data is not corrupted during the playing of the explanatory sequence and user control over the keyboard and mouse is disabled to prevent the user from interfering with the demonstration. The text from conventional help screens may also be displayed on the screen during the demonstration in order to further assist the user.

Claims

a demonstration player stored in the memory and responsive to the demonstration commands for generating input commands reflective of the customized desktop of the application program and the display screen at the time of suspension;

means for applying the input commands to the application program as simulated user input commands to cause the application program to perform a help demonstration starting with the customized desktop as it is displayed at the time of suspension; and

a mechanism which resumes operation of the application program after the help demonstration ends.

2. Apparatus according to claim 1 wherein the list of demonstration commands comprises a script file.

3. Apparatus according to claim 1 wherein the demonstration player is responsive to the demonstration commands for communicating with the application program to determine the position on the display screen of a graphic image.

4. Apparatus according to claim 1 wherein the demonstration player is a software program running as a process separate from the application program.

5. Apparatus according to claim 1 wherein the memory has an address space within which the demonstration player runs and an address space within which the application program runs.

6. Apparatus according to claim 5 wherein the memory includes a global portion which is accessible by both the demonstration player and the application program and wherein the demonstration player communicates with the application program through the global memory portion.

7. Apparatus according to claim 1 further comprising error correcting code in the demonstration player which operates before the demonstration player generates input commands for changing the customized desktop of the application program and the display screen in order to prevent errors from occurring during the help demonstration.

8. Apparatus according to claim 1 further including a plurality of demonstration command lists and means responsive to a user command for selecting one of the demonstration command lists.

9. Apparatus according to claim 1 wherein the demonstration player includes means for preventing user commands from controlling the application program.

10. A method for use on a computer system having a display screen, a memory and user-controlled means for generating input commands, the method generating an animated help demonstration on the display screen for teaching a user to operate a feature of an application program, the method comprising the steps of:

A. storing a list of demonstration commands in the memory, the demonstration commands including position query commands and control commands;

B. suspending the operation of the application program;

C. using the position query commands to detect a customized desktop of the application program and the display screen at the time of suspension and to change the list of demonstration commands to accommodate the application program customized desktop;

D. applying the demonstration commands to a demonstration player to cause the demonstration player to generate input commands reflective of the customized desktop of the application program;

E. applying the input commands to the application program as simulated user input commands to cause the application program to perform a help demonstration; and

F. resuming operation of the application program after the help demonstration ends.

11. A method according to claim 10 wherein step A comprises the step of:

A1. storing a script file in the memory.

12. A method according to claim 10 wherein step C comprises the step of:

C1. applying a position query command to the demonstration player to cause the demonstration player to communicate with the application program to determine the position on the display screen of a graphic image.

13. A method according to claim 10 wherein step C comprises the step of:

C2. running a demonstration player software program as a process separate from the application program.

14. A method according to claim 13 wherein step C comprises the step of:

C3. running the demonstration player software program in a first address space in the memory; and

C4. running the application program in a second address space in the memory.

15. A method according to claim 14 wherein the memory includes a global portion which is accessible by both the demonstration player and the application program and wherein step D comprises the step of:

D1. causing the demonstration player to communicate with the application program through the global memory portion.

16. A method according to claim 10 wherein step D comprises the step of:

D2. changing the customized desktop of the application program and the display screen before applying the demonstration commands to the demonstration player in order to prevent errors from occurring during the help demonstration.

17. A method according to claim 10 wherein step A comprises the step of:

A2. storing a plurality of demonstration command lists in the memory; and

the method further comprises the step of;

G. selecting one of the demonstration command lists in response to a user command.

18. A method according to claim 10 further comprising the step of:

H. preventing user commands from controlling the application program.

19. Apparatus for use on a computer system having a displays screen with a plurality of graphic control images displayed thereon, a memory and user-controlled means for generating input commands, the apparatus generating an animated help demonstration on the display screen for teaching a user to operate a feature of an application program, the apparatus comprising:
