IUI

IUI has successfully established itself as a unique, interdisciplinary conference, at the intersection of Artificial Intelligence and Human-Computer Interaction. The Conference receives contributions from many traditional as well as hot topics in the field, ranging from Multimodal Interfaces and Recommender Systems, to Affective Computing and Brain-Computing Interfaces.

Because of this ever-increasing diversity of topics, this edition has seen further changes to our reviewing process. We have introduced a rebuttal phase for Long Papers, following a trend adopted by several high-quality conferences. The objective of the rebuttal is to ensure greater transparency and fairness, as the authors' responses should influence the discussion phase moderated by a Senior Program Committee (SPC) member.

In order to ensure that all topics were adequately covered over 200 reviewers have contributed to the selection of this year's program and we trust that this had a very positive impact on the relevance and quality of individual reviews.

We have retained the successful format of the conference with Long Papers, Short Papers and Demonstrations. In addition, we have addressed the issue of conversion of Long Papers into Short Papers by explicitly requesting authors' approval at submission time.

The accepted submissions cover a wide range of topics, including personalized information systems, intelligent user interaction for information search and browsing, affective computing, gesture-based systems, and multimodal user interfaces. Geographically, the accepted work also represents researchers and institutions in many countries across four continents, including China, Japan, Korea, Singapore, Canada, Netherlands, Ireland, France, Germany, Australia, New Zealand, United Kingdom, and the United States of America.

As always, the selection process has been the object of careful consideration and multiple discussions. We have asked the SPC moderators to formulate recommendations for acceptance and in the vast majority of cases it has been straightforward for us to endorse their choice. It is always down to the Program Chairs to make final decisions, sometimes difficult ones, on the total number of papers to be accepted. We have adopted a continuity policy from previous editions (around 22% for Long Papers), this year's overall acceptance rate achieves the right balance between selectivity and openness to innovative papers.

The conference program highlights two invited talks: Paul Sajda, from Columbia University and Kazuo Yano, from Hitachi's Advanced Research Laboratory.

This year's Conference will also feature five full-day and one half-day workshops, covering several hot topics in the area of IUI, with strong emphasis on semantics, social aspects and multimodality of interfaces, including:

• Social Recommender Systems

• Intelligent Visual Interfaces for Text Analysis

• Multimodal Interfaces for Automotive Applications

• Interoperability and Interaction on the Social and Semantic Web

• Eye Gaze in Intelligent Human Machine Interaction

• Semantic Models for Adaptive Interactive Systems

The demonstration program accepted fifteen regular submissions. We would like to thank Tyler Baldwin and Brian Romanowski for their help in organizing the demo session.
