....operators represent the lowest abstraction level. Compare to other hierarchical planning system, our approach achieves more computational efficiency by reducing the amount of search needed. It also eases the task of knowledge encoding. Similar approaches to hierarchical planning can be found in [6][7] As in [7] we have decided to use a distributed blackboard architecture, in which each blackboard structure (agent or specialist) is in charge of the plan design in a certain abstraction level. Therefore, a primitive operation in a blackboard of abstraction level i, corresponds to a native ....

....[14] State of the Art Dynamic 3D learning environments call for an approach to camera planning that can represent and draw inferences about the visual structure of information to be presented to users. A growing number of projects have addressed the fundamental problems of multimedia planning [2, 15, 16, 12, 25], automated illustration [22] and animated interface agents [23, 3, 19] Work has also begun on camera control, for which three approaches have been proposed. In the offline approach of ESPLANADE [11] and the batch version of DCCL [6] camera planning systems operate in batch mode and hence ....

....pedagogical agents with full scale realtime natural generation will yield important increases in communicative flexibility. Finally, developing techniques for marrying lifelike pedagogical agent technologies with 3D explanation generators [Karp and Feiner, 1993, Bares and Lester, 1997, Butz, 1997, Zhou and Feiner, 1997] may create a qualitatively better form of learning environment. We will be exploring these directions in our future work.

.... plan to select and partially order information for the presentation, taking into account the caregiver the briefing is intended for (nurse or physician) The media allocator allocates content to media, and finally, the media specific generators realize content in their own specific media (see (Zhou and Feiner, 1997) for details on the graphics generator) A media coordinator is responsible for ensuring that spoken output and animated graphics are temporally coordinated. Within this context, the speech generator receives as input a partially ordered conceptual representation of information to be ....
