Abstract

A user-adaptive audio and/or video presentation system contains a background sub-system for presenting audio and/or video items, control for the background subsystem as regarding an actual selection sequence amongst the items according to a user preference pattern, and output means for physically presenting selected items to a user. Each item has a uniformly structured first set of static attribute data and associated second set of weight value data, and a third set of dynamic behaviour data. The dynamic behaviour of the items is collectively governed by behavioral and interactivity prescriptions, so that each respective item represents an autonomous agent. The control includes processing for under influence of the first and second sets of data and as governed by the prescriptions, updating weight and dynamic behaviour parameter data of each item versus other items for subsequently influencing the controlling.

Claims

1. A user-adaptive audio and/or video presentation system containing a background presentation sub-system for presenting audio and/or video items, control means for controlling said presentation sub-system as regarding an automatically generated selection sequence amongst said items according to a user preference pattern, and output means for physically presenting selected items to a user,

wherein each said item has a uniformly structured first set of static attribute data and associated second set of weight value data indicating relevance of the static attribute data, and also a third set of dynamic behaviour parameter data, and said items are with respect to their dynamic behaviour collectively governed by a set of behavioral and interactivity prescriptions, so that each respective item represents a respective autonomous agent, and said control means include processing means for under influence of said first and second sets of data and as governed by said prescriptions, updating said weights and dynamic behaviour parameter data of each item in question vis a vis other said items for subsequently influencing said controlling.

2. A system as claimed in claim 1, wherein said behaviour is metaphored as motion within a finite space of at least two dimensions.

3. A system as claimed in claim 1, and being arranged for forming among said items one or more temporary association clusters which forming is conditional to similar behaviour amongst the respective item agents in such cluster, and said presentation favours an item pertaining to a most recently accessed said cluster.

4. A system as claimed in claim 3, wherein associating to a cluster is subject to arising of a sense_-- item situation, followed by detected similarity in an observe_-- item situation.

5. A system as claimed in claim 1, wherein said updating is enabled for a particular said item independent of actual scheduling for presentation thereof.

6. A system as claimed in claim 1, and having user evaluation input means for selectively influencing said updating at least with respect to said weight value data for a particular item through an evaluatory physical input.

7. A system as claimed in claim 6, wherein said particular item is the item presented most recently.

8. A system as claimed in claim 6, wherein said influencing and updating is effective on a whole-cluster basis.

9. A system as claimed in claim 1, and having freeze means for blocking autonomy of said agents, and thus freezing said behaviour as dictated by said autonomy.

10. A system as claimed in claim 1, for use in a multimedia environment.

11. A system as claimed in claim 1, and allowing simultaneous access at a plurality of user stations.

12. A system as claimed in claim 1, wherein said presentation sub-system is a storage system for storing and accessing audio items which are distributed amongst a plurality of physical media instances that each allow collective storage of a plurality of such items.

13. A system as claimed in claim 1, wherein said presentation system is a storage system with write feasibility for accommodating storage of said dynamic parameter data or other calculated data after formation of the latter.

14. A method for user-adaptive audio and/or video presentation comprising the steps of:

selectively accessing a background presentation sub-system for presenting audio and/or video items according to a user preference pattern, and physically outputting selected items to a user,

wherein operating each such item as an autonomous agent on the basis of a uniformly structured first set of static attribute data and associated second set of weight value data indicating relevance of static attribute data, and also a third set of dynamic behaviour parameter data associated to the item, and furthermore through behavioral and interactivity prescriptions for governing their collective dynamic behaviour, and by under influence of said first and second sets of data and as governed by said prescriptions, updating said weights and dynamic behaviour parameter data of each item in question vis a vis other said items for subsequently influencing said controlling.
