Proceedings of the 18th Australia conference on Computer-Human Interaction: Design: Activities, Artefacts and Environments

The theme of the OZCHI 2006 conference in Sydney, Australia is design: activities, artifacts and environments. The program has been designed to approach this theme from both the research and practitioner worlds. Our keynote speakers, Genevieve Bell, Donna Maurer and William Gaver were selected to provide both academic and industry perspectives on this theme.This year's OZCHI conference received 70 long paper and 72 short paper submissions. From these submissions, 36 long and 36 short papers were selected to appear at the conference. All submitted long and short papers were subjected to double-blind peer review by an international reviewing committee. Long papers were reviewed by at least three peers. Short papers were reviewed by at least two peers. Industry case studies, panels, and workshop and tutorial proposals were reviewed by their respective track chairs.The OZCHI proceedings are a publication of CHISIG, and will also appear as part of the ACM (the Association for Computing Machinery) International Conference Proceedings Series. This means that the OZCHI 2006 Proceedings will be available internationally from the ACM digital library shortly after the conference (http://portal.acm.org/dl.cfm). As in previous years, OZCHI 2006 presents an award for the best long paper, the Gitte Lindgaard award, recognising the best written paper, in combination with the quality of the presentation and discussion at the conference. We are also pleased to offer a dedicated Industry stream, following the theme of the conference and running in a parallel for the first two days.
