This special issue on "Knowledge-based Environments and Services in Human-Computer Interaction" aims at presenting some novel environments and services and relevant challenging issues and proposed solutions that allow users to interact with computers more efficiently.As computer users are spreading and include people of all ages, backgrounds, professions, education levels, aims, profiles, preferences and personalities, human-computer interaction has to undertake the difficult task of user modeling, personalization, adaptivity, virtual reality, intelligent multimedia interaction and so on.The special issue focuses on both theoretical issues as well as applications of intelligent environments for human-computer interaction including challenges, open research issues, design methodologies, user interface development life cycle, empirical studies, multimedia/multimodal signal processing and evaluation.We have received a large number of submissions to the special issue.Each submitted paper was reviewed by at least two independent reviewers for novelty and clarity of the research reported in it.Additionally, as guest co-editors, we looked over all the manuscripts.For inclusion in the special issue, we have selected six papers from those submitted.The first two papers describe novel user modeling approaches in human-computer interaction environments.Specifically, the first paper, authored by Savvopoulos and Virvou, is on a "User Modelling Server for Adap-
