PERSUASIVE

We are delighted to welcome you to the beautiful campus of Claremont Colleges for PERSUASIVE 2009. We hope you will enjoy the location, the social program and the outstanding technical program that we have assembled for you.

This is the fourth year for the International Conference on Persuasive Technology. This community studies both the theory and practical applications of how computing technology can alter human behavior and attitudes. In a very short time, this new discipline has garnered attention from technologists, researchers and practitioners world-wide. That is evident from this year's technical program with many papers representing new ideas in design, healthy lifestyle, green technologies, social networking and mobile persuasive gaming solutions.

From the general Call for Papers, we received 66 paper submissions, 3 tutorial proposals and 3 panel proposals for a total of 72 submissions. Each paper and submission went through a double blind review process. Each paper received at least 2 reviews. The papers were reviewed by our technical program committee but we also had to enlist a number of additional reviewers. The program co-chairs met and carefully went through every review and finally selected 21 papers for full presentation. That makes it an acceptance rate of 31%. In addition to full papers, we accepted 15 excellent papers for presentation at the poster session. All papers and posters appear in their entirety in the conference proceedings.

This year we are pleased to inform you that ACM will publish the proceedings and make all papers available through their digital library. This will make it easy for researchers to search and access Persuasive 2009 papers.

Besides the papers and posters, the program includes two exciting keynote lectures, three distinguished lectures by leaders in our field, and three thought-provoking panels. On Sunday, April 26th, 2009, we have arranged two cutting-edge tutorials for which many have registered. We also would like to thank Prof. Matti Rossi for arranging the doctoral consortium.
