Abstract: 

The multimodal featuring fusion for natural human-computer interaction 
involves complex intelligent architectures to face unexpected errors 
and mistakes made by users. These architectures should react to events 
that occur simultaneously with eventual redundancy from different input 
media. In this paper, intelligent agent based generic architectures for 
multimedia multimodal dialog protocols are proposed. Global agents are 
decomposed into relevant components. Each element is modeled separately 
using timed Colored Petri networks. The elementary models are then linked
together to obtain the full architecture. Hence, maintainability, 
understandability and the modification of the architecture are facilitated.
For validation purpose, the proposed multi-agent architectures are applied 
on a practical example.
