2006 Summary

• Several types of settings / corpora required– Human-Computer Interaction: GUI, ECA, robot– Human-Human: TV, Cartoon, Meetings,

Conversations, scenario based or not– Human modalities: hand gestures, audiovisual

speech, head, gaze, interpersonal distance– Top-down vs. bottom-up approaches– Evaluation & validation of annotation– Duration of videos data, Nb of video taped people– Media : audio, image, sensors

2006 Summary• Research questions

– Capturing semantics and pragmatics of modalities– Social behavior– Dynamics of individual vs. group behavior– Topic of attention, functional role– Turn management, sequencing, feedback – Interaction loops at multiple levels vs. high level dialogue– Level of embodiment (robot / ECA)– Temporal relations between modalities– Cultural & individual differences– Naturaleness of corpora– Mapping between different schemes– Complementarity between manual & automatic annotations– Emotion related states & mm behavior (expressivity)– Workshop on Emotional Corpora

(L. Devillers, J.C. Martin, E. Cowie, R. Cowie, A. Batliner)

2006 Summary

• Practical questions– Methodological steps

(basic functions vs. Full-fledged complexity)– Dissemination/availability of corpora

(Grenoble, Norway, …)– Cooperations

(e.g. meetings, multilinguality)

6

2006 Summary

• Cross disciplinary: linguists, computer sc., …• International projects: HUMAINE, Similar, AMI,

CHIL, CALO, ATR• Towards « standards »

– Abstract coding: gesture, facial expr., – Language

• W3C EMMA• Emotion EARL (cf WS Emotions)

– Tools : Anvil used a lot

• Decrease of participation ?

Next steps• Related meetings

– LREC 2008 / Interspeech / Intelligent Virtual Agents– Other Communities (e.g. expressive robotic)– IPRA07 : more theoretical incl. WS Multimodal pragmatics & corpus– ICMI07 : more technological, evaluation + application of mm corpora

• Topic of next Multimodal WS– From corpora to application / studying phenomena– Data driven models– Standardisation– Tools usability– Animated character as perceptual tools– Focused scheme vs exploratory scheme– Machine Learning (ex export from annotations to WEKA)– Manual and automatic annotations– Cooperation HH vs HCI

• Scientific maturity, Special issue of journal with open call
