ILHAIRE was an FP7 project exploring the recognition of the affective nuances of laughter and how these are expressed multimodally.

Laughter is a complex, multi-modal phenomenon and important non-verbal affective communicative signal between humans. It is posited that such significance will persist on incorporating laughter into human-machine interaction and that future technologies capable of recognising and responding appropriately to the affective cues of non-verbal communications modalities such as laughter will provide enjoyable, powerful interaction styles. Increasing affective computing research effort focuses on how non-verbal cues such as body movement, facial and vocal expressions can be used in machine recognition of affect, but laughter body movement has not yet been examined.
