The Interaction-Design.org Foundation is a labour of love founded by Mads Soegaard in 2002, and in 2010, his wife, Rikke Dam, joined the project (and their exotic office on a semi-deserted island in Thailand). Apart from Rikke and Mads, hundreds of people have helped out and continue to do so.
They are on a mission to make free and open educational materials: There are so many great minds in the human-computer interaction and interaction design community and they want to empower these authors to reach all their interested readers around the world.
Their currently featured chapter (one out of nine) is an authoritative overview of Social Computing by Tom Erickson – veteran researcher at IBM Research Lab. It includes 9 HD videos filmed in Copenhagen and commentaries by renowned designers/researchers like Elizabeth Churchill from Yahoo! and Andrea Forte.
