Events in the cyberspace can be modeled as a spatiotemporal continuity populated by computing devices, communication channels, and multimodal interactions. Contemporary ubiquitous devices unleash the boundary of one-to-one human-computer interaction. E.g., it has become a de facto style of facilitating social events that participants use several distributed devices through multimodal interaction. How people access multimodal media in different context is an interesting yet challenging problem. Ubi-media Computing, as it is bravely defined, brings together technologies for location/context adaptation, inter-device interaction/reaction, and media/data communication. In line with the blooming technologies realizing the above concepts, this international conference looks at the state-of-the-art and original research issues to be published in the proceedings. New contributions include three perspectives: devices that realize ubiquitous computing, multimodal interactions between human and these ubiquitous devices, and the need of adaptive multimedia.
