    "laughter" : { value, confidence },
    "excitement" : { value, confidence },
    "surprise" : { value, confidence }
   }
}

The valence field contains a value with a value from -1 (negative) to 1 (positive), with a confidence from 0 to 1. All other fields contain a value with its confidence, both ranging from 0 to 1.

PersonState ALMood::personStateFromPeoplePerception(unsigned int ID)

Get the emotional state of the user with the identifier ID from PeoplePerception through a PersonState struct.

Parameters:
Returns:
