Topics of interest include but are not limited to: Multimodal interaction processing Machine learning, pattern recognition and signal processing approaches for the analysis and modeling of multimodal interaction between people and among the different modalities within people; adaptation and multimodal input fusion and output generation, addressing any combination of: vision, gaze, audio, speech, smell/olfaction, taste, gestures, pen input, haptic and tangible, bio-signals such as brain, skin conductivity, etc. Interactive systems and applications Mobile and ubiquitous systems, automotive and navigation systems, human-robot and human-virtual agent interaction, virtual and augmented reality, education, authoring, entertainment, gaming, telepresence, assistive and prosthetic systems, brain-computer interfaces, universal access, healthcare, biometry, intelligent environments, meeting analysis and meeting spaces, indexing, retrieval and summarization, etc. Modeling human communication patterns The modalities and the applications named above lead to a need for multimodal models of human-human and human-machine communication, including verbal and nonverbal interaction, affordances of different modalities, multimodal discourse and dialogue modeling, modeling of culture as it pertains to multimodality, long-term multimodal interaction, multimodality in social and affective interaction, multimodal social signal processing. Data, evaluation and standards for multimodal interactive systems Design issues, principles and best practices and authoring techniques for human-machine interfaces using any combinations of input and/or output multiple modalities. Architectures; assessment techniques and methodologies; corpora; annotation and browsing of multimodal interactive data; W3C and other standards for multimodal interaction and interfaces, evaluation techniques for multimodal systems. Urban Interactions Interactions with the city, urban computation, smart cities, applications to promote energy conservation and healthy living, interactive public spaces, interactive artworks in the city, applications for inclusion in metropolitan areas, mobile applications for interacting with the city, crowdsourcing via urban interactions.
