Welcome to the 6th International Conference on Ubiquitous Information Management and Communication (ICUIMC) 2012. This year the conference is held in Kuala Lumpur - Malaysia, a city dominated by the tallest skyscrapers in Southeast Asia and flushed with the proceeds of international trade and commerce. The ACM ICUIMC 2012 aims to provide a forum promoting new visionary approaches and interdisciplinary researches. The conference explores emerging interests and novel ideas in the area of information management, communication technologies and their implications for social interaction. This has also served as one of the most essential platforms for researchers and developers to exchange innovative ideas, information and significant research achievements; and provides a unique opportunity in which both technology and social science meet. Two main tracks for information processing management and communication will be held, covering both research and application works of information management, intelligent information processing, interaction management, networking/telecommunications, and social interaction. The conference includes two outstanding keynote speeches, 14 oral sessions, and three poster sessions. This year's program is extremely strong, and the review process was very competitive and rigorous. We received 456 submissions from many countries around the world. As a result of a careful review process, we selected 131 papers to be presented in the oral and poster sessions (28% acceptance rate). All of accepted papers not only provide novel ideas, new results, work in progress, and state-of-the-art techniques, but also stimulate future research activities in the area of information management and communication technologies.
