Automatic analysis of rapport

A system comprising:

• one or more processors;
• and
• a memory coupled to the one or more processors and comprising computer code which, when executed by the one or more processors, causes the one or more processors to:
• receive a data stream from a first participant;
• generate a stream of estimates of a degree to which a predetermined emotion or affective state corresponds to a classifier of a plurality of classifiers based on the data stream;
• detect one or more temporal signal patterns over time in the stream of estimates;
• receive a second data stream from a second participant;
• generate a second stream of estimates of a degree to which a predetermined emotion or affective state corresponds to a second classifier of a second plurality of classifiers based on the second data stream;
• detect one or more second temporal signal patterns over time in the second stream of estimates;
• correlate at least one of the one or more second temporal signal patterns with at least one of the one or more temporal signal patterns;
• and
• estimate an interaction quality of an interaction between the first participant and the second participant based on:
• the correlated second temporal signal patterns, the detected one or more temporal signal patterns, and the detected one or more second temporal signal patterns, wherein the estimate of the interaction quality comprises an estimate of a level of rapport between the first participant and the second participant.
