A total of 4,039individuals from academia,researchinstitutes, industry and governmental agencies from 67 countries submitted contributions, and 1,318 papers that were judged to be of high scientific quality were included in the program. These papers address the latest researchand development efforts and highlightthehumanaspectsofdesignanduseofcomputingsystems.Thepapers accepted for presentation thoroughly cover the entire field of human–computer interaction, addressing major advances in knowledge and effective use of com- puters in a variety of application areas. This volume, edited by Constantine Stephanidis, contains posters’ extended abstracts addressing the following major topics: • Design methods, techniques and knowledge • Usability and user experience • Cultural, cross-cultural and aesthetic issues in HCI • Cognitive and psychologicalissues in HCI • Inclusive design and accessibility • Social interaction and on-line communities • Work and collaboration • Access to information and knowledge The remaining volumes of the HCI International 2011 Proceedings are: • Volume 1, LNCS 6761, Human–Computer Interaction—Design and Devel- opment Approaches (Part I), edited by Julie A.
