I just posted three videos of the recent Interaction09 conference on Core77:

Dan Saffer – Attention Awareness for Interaction Designers 2009
Dan Saffer calls out the Interaction Design community for allowing distracting topics to consume our attention, and for paying too little attention to “moonwalking bears,” the opportunities interaction designers can take advantage of in the near future.

Robert Fabricant – Behavior is our Medium
Robert Fabricant talks about Interaction Design as a practice beyond just computing technology. He gives examples of Interaction Design as far back as ancient history, all the way to a humanitarian project underway today. He shows that Interaction Design’s primary medium is behavior, extending far past the high technology world into the realm of human behavior and relationships.

John Thackara – Designing for Business as Unusual
John Thackara shows the ways in which business as we know it are about to change for good, and then identifies how interaction designers can take these challenges on as design problems.
