This video is a simple and straight forward video, in which Bill Verplank explains what interaction design is all about (from the series of videos that accompanies Bill Moggridge’s book “Designing Interactions”). Given that we are often asked just what Interaction Design is and why it is so important, it is important to learn how to speak the language of what we do in a way that the client can understand. In order to do that you must learn to understand all you can about your client then you can help them understand why what we do is so valuable to them personally.
