One of the most ambitious sources of (open) scholarship in the field of HCI and interaction design is today found at Interaction-Design.org. This site is filled with content from some of the most distinguished researchers and designers in the field. I just got an email from interaction-design.org about their newest addition to the encyclopedia. It is an article called Philosophy of Interaction and the Interactive User Experience. The article is written by Dag Svanaes and has substantial comments from Don Norman and Eva Hornecker. Svanaes is ambitious in his approach to reveal the philosophy of the field. This is highly recommendable even for those who might not agree with his analysis. We definitely need more texts like this in the field. Many more.
It is great that we do have interaction-design.org as a source of quality materials that is also free to anyone interested. The site also includes a great calendar of conferences and deadlines and bibliographies of many researchers in the field. Mads Soegaard who is the Editor-in-Chief for this endeavor is doing a great job.
