This volume summarizes the works and new research results presented at the Sixth International Conference on Intelligent Interactive Multimedia Systems and Services (KES IIMSS2013) which took place in June 26-28, 2013 Sesimbra, Portugal. KES IIMSS is a well established international annual conference within the KES International series of conferences that focuses on research in the fields of intelligent interactive multimedia systems and services. The aim of the IIMSS conference is to provide an internationally respected forum for scientific research in the technologies and applications of intelligent interactive multimedia systems and services.

IIMSS2013 consisted of keynote talks, oral presentations, invited sessions and workshops, on the applications and theory of intelligent interactive multimedia systems and services and related areas. IIMSS2013 provided excellent opportunities for the presentation of interesting new research results and discussion about them, leading to knowledge transfer and generation of new ideas.

IIMSS2013 received many submissions of high quality. The submitted papers were reviewed by at least two reviewers. Not all submissions could be accommodated for presentation at the conference. Finally, 37 papers were accepted for presentation at the IIMSS2013 and inclusion in its Proceedings. We are very satisfied with the quality of the program and would like to thank the authors for choosing KES-IIMSS as the forum for presentation of their work. Also, we gratefully acknowledge the hard work of KES-IIMSS international program committee members and of the additional reviewers for taking the time to review the submitted papers rigorously and select the best among them for presentation at the conference and inclusion in its proceedings.

We are also grateful to the KES personnel for their wonderful work in maintaining the IIMSS2013 site. Finally, we would like to thank the IOS Press personnel for their wonderful job in producing this Proceedings.
