What is “Interaction Design” anyway?

The latest podcast from Lunar Design’s Icon-o-Cast is titled WHAT IS “INTERACTION DESIGN,” ANYWAY?

It’s kind of basic, but nevertheless it’s nice to hear it from a consultancy bureau. I feel it’s a good introduction on Interaction Design. Gretchen Anderson sounds a bit Swedish, but apparently she studied at Harvard and been working at Frog for some years, and she is now Director of Interaction Design at Lunar.
