ThisvolumecontainstheProceedingsofthe2ndInternationalSymposiumon Intelligent Interactive Multimedia Systems and Services (KES-IIMSS 2009) This second edition of the KES-IIMSS Symposium was organized by the Department of Information Technologies of University of Milan, Italy in c- junctionwithHanyangUniversity,KoreaandKESInternational. KES-IIMSS is a new series of international scienti?c symposia aimed at presenting novel research in the ?elds of intelligent multimedia systems relevant to the dev- opment of a new generation of interactive, user-centric services. The major theme underlying this year's symposium is the rapid integration of mul- media processing techniques within a new wave of user-centric services and processes. Indeed, pervasive computing has blurred the traditional disti- tion between conventional information technologies and multimedia proce- ing, making multimedia an integral part of a new generation of IT-based interactive systems. The aim of the KES-IIMSS symposium, following the general structure of KES events, is to provide an internationally respected forum for publishing high-quality results of scienti?c research while all- ing for timely dissemination of research breakthroughs and novel ideas via a number of autonomous special sessions and workshops on emerging - sues and topics identi? ed each year. IMSS 2009 co-located events include the International Workshop on Human-Computer Interaction in Knowled- based Environments, and three invited sessions respectively on Intelligent Systems for Healthcare, Design of Intelligent Environments for Supporting Human Interaction and Multimedia Techniques for Device and Ambient - telligence (MTDAI).
