  • Patent number: 9619018
    Abstract: In one example, a method for multimodal human-machine interaction includes sensing a body posture of a participant using a camera (605) and evaluating the body posture to determine a posture-based probability of communication modalities from the participant (610). The method further includes detecting control input through a communication modality from the participant to the multimedia device (615) and weighting the control input by the posture-based probability (620).
