Claim:
1. A method for multimodal human-machine interaction comprising: sensing a body posture of a participant using a camera; evaluating the body posture to determine a posture-based probability that certain modalities of communication will be presented by the participant based on the body posture, the posture-based probability being calculated using a processor in a multimedia device; wherein the modalities of communication comprise gestural and vocal; precluding, as input o the processor, a gestural modality of communication based on a determination that the calculated posture-based probability of the gestural modality of communication is below a predetermined level while receiving as input the vocal modality of communication; detecting control input presented via a modality of communication by the participant using a sensing device in the multimedia device; weighting the control input by the posture-based probability to determine a command to associate with the control input; and wherein calculating the posture-based probability of the gestural modality of communication is accomplished according to the following formula: where
