Abstract

A control engine (12) downloaded by a server (1) to a student computer (2) instantiates panel objects (16) and multiple media objects (15) linked to each panel object (16). At any one time multiple media objects (15) operate simultaneously and in synchronism to generate multiple display and sound outputs for comprehensive learning output and student interaction. The media objects (15) operate autonomously, without even knowing their places in their respective hierarchies, thus allowing dynamic updates from the server (either server-driven or student-driven). Synchronization is achieved by the panel object activating the multiple relevant media objects for a panel and the media objects using time value attributes to control activation and termination times. The media objects access (84 )a stacking mechanism (82) in real time to determine a linked panel or media object to implement an operation in response to an event such as progression to a next panel. In addition to distributing objects in real time, the stacking mechanism (82) also dynamically modifies some objects by scripting or method invocation.

Claims

1. A method of operation of a computer-based learning system, the method comprising the steps of:

a student computer executing control engine code to instantiate a plurality of media objects in real time to launch a course, each media object having code and attributes for autonomously outputting content from a content source;

the control engine, in response to an event, activates a plurality of said media objects for simultaneous and synchronized operation to provide the plurality of content outputs together as a panel in a student interface; and

the control engine dynamically maintains relationships between the media objects according to real time updates from a server.

2. A method as claimed in claim 1, wherein the control engine instantiates a panel object for each panel.

3. A method as claimed in claim 2, wherein the panel object executes control engine code to activate the media objects for its panel.

4. A method as claimed in claim 2, wherein a media object responds to a real-time event by accessing a stack mechanism to determine its links to other media objects or the panel object.

5. A method as claimed in claim 4, wherein the stacking mechanism is dynamically updated in response to download of updates by the server.

6. A method as claimed in claim 5, wherein the update comprises a mark-up language file, and the student computer parses the mark-up language files to perform an update.

7. A method as claimed in claim 4, wherein each media object makes a request to the stacking mechanism using a generic method call.

8. A method as claimed in claim 7, wherein the stacking mechanism recognizes the calling media object by its identifier transmitted with the request.

9. A method as claimed in claim 8, wherein the stacking mechanism returns an object, and the requesting media object uses the returned object to perform an interactivity operation in synchronism with the other objects.

10. A method as claimed in claim 4, wherein the stacking mechanism stores media and panel objects associated with identifiers of linked objects.

11. A method as claimed in claim 4, wherein progression from one display panel to another display panel on the student computer is in response to an event generated by student input at a button controlled by a media object associated with a first panel object, said media object accesses the stacking mechanism to retrieve a second panel object, and the second panel object activates linked media objects to render panel visual displays and generate output sound.

12. A method as claimed in claim 11, wherein direction of a course is dynamically modified by on-the-fly modification of the stacking mechanism in response to an event raised by the student interface.

13. A method as claimed in claim 4, wherein the media objects automatically poll the stacking mechanism to determine relationships in real time.

14. A method a claimed in claim 4, wherein the stacking mechanism performs dynamic modification of media objects.

15. A method as claimed in claim 14, wherein the stacking mechanism comprises scripting objects, each of which is programmed to dynamically modify the code of a requesting media object, by modifying a primitive object and inserting it as a contained object in the requesting media object.

16. A method as claimed in claim 14, wherein the stacking mechanism performs method invocation on media objects stored in the stacking mechanism.

17. A method as claimed in claim 2, wherein the group of media objects linked with a panel object self-synchronize for co-ordinated output of content for a panel.

18. A method as claimed in claim 17, wherein each media object has as an attribute an activation time value counted from a base reference.

19. A method as claimed in claim 18, wherein each media object has a termination time value attribute counted from the activation time.

20. A method as claimed in claim 18, wherein the base reference time is time of linking of the media objects for a panel in response to an event.

21. A method as claimed in claim 1, wherein each media object comprises a plurality of groups of attributes, at least one of said groups including display screen positional and dimensional values, and time data.

22. A method as claimed in claim 1, wherein at least one media object contains a contained object.

23. A method as claimed in claim 22, wherein said media object has an attribute acting as a root for the contained object, followed by contained object attributes.

24. A method as claimed in claim 23, wherein said contained object attributes include synchronization time parameters, based on time references within a time range of time attributes of the containing object.

25. A method as claimed in claim 1, wherein the control engine launches a course by dynamically instantiating the media objects in response to an instantiation file received from the server.

26. A method as claimed in claim 25, wherein the instantiation file comprises mark-up language tags, including a root tag for each media object to be instantiated, each root tag being followed by parameter values, and the control engine parses the instantiation file to identify the root tags and use the parameters to apply the media object'"'"'s attributes.

27. A method as claimed in claim 1, wherein a media object generates interlude entertainment not directly related to learning content of a course.

28. A method as claimed in claim 27, wherein said media object includes a timer for self-activation at random intervals.

29. A method as claimed in claim 1, wherein a media object generates a video of a presenter presenting course content.

30. A method as claimed in claim 1, wherein a media object generates graphics and dynamic animations.

31. A method as claimed in claim 30, wherein the animations are synchronised with the presentation.

32. A method as claimed in claim 1, wherein a media object generates bullet points synchronised with a video presentation.

33. A method as claimed in claim 1, wherein a media object generates a summary of bullet points of a full chapter.

34. A method as claimed in claim 1, wherein a media object maintains a database of evaluation questions, and generates an evaluation set of questions for response by the student.

35. A method as claimed in claim 34, wherein the media object applies a time limit on each question.

36. A method as claimed in claim 1, wherein a media object generates simulations.

37. A method as claimed in claim 1, wherein a media object controls the level at which a simulation is generated according to student progress.

38. A computer based learning system for performing a method as claimed in claim 1.

39. A computer program product comprising software code for performing operations of a method of claim 1 when executing on one or more digital computers.
