I participated in the 5th Persuasive Technology conference in Copenhagen and at the end they announced that the next one (2011) will be in Ohio. I was trying to find the date to check if it overlaps with other HCI conferences that I want to attend, but couldn’t find this information anywhere on the internet. So I emailed Harri Oinas-Kukkonen and asked more information. He kindly forwarded me an email from the organizers, as follows:

The Sixth International Conference on Persuasive Technology will be held at Ohio State University (Columbus, OH, USA) from June 2-5th, 2011.

The 2011 Conference will build on themes from the earlier conferences. A special emphasis for the 2011 Conference will be Persuasive Technology: Enhancing Sustainability and Health.

Papers on research, theory, and methods from a wide range of disciplines are invited for submission to the conference. An interdisciplinary Doctoral Seminar, sponsored by the Association for Consumer Research and the Society for Consumer Psychology, will follow the conference. An overall goal of the conference program, conference activities, and subsequent publications will be the development and enhancement of global interdisciplinary connections. Selected papers from the conference may be published in special issues of high quality journal outlets.

Full length papers (preferred) or extended abstracts should be submitted […] by March 5th, 2011
Conference Co-chairs are Curtis P. Haugtvedt and David Ewoldsen

More details about the conference venue will be available on at Persuasive2011.org. Details regarding last year’s conference can be found at Persuasive2010.org.

He commented that this deadline is quite late (and I agree), less than 3 months before the conference itself, so it might be a provisional date.
