Seminar Task 'Interaction design is an applied art'

After reading the interview with Dan Saffer on his experience through interaction design i completely agree with the statement that 'Interaction design is an applied art'
In my opinion you see the statement from his point of view, interaction design is an extension of original print graphic design. It's a new challenge and concept of how to advertise to consumers and a new platform to design on.
The more insight you get into his day to day life it takes a certain type of designer to recognise a customers needs and deliver the solution to these needs on such a scale that it will effect an audience to the biggest limits it can reach.
From studying graphic design at college, understanding a customers basic needs is more than creating basic information and sticking it on a platform. And i think that taking a lot of design digital is an amazing development that both designers and consumers can really make the most out of using. However you see the problems where too many people think just using the information they have and putting it somewhere where a lot of people can read it, will be enough, and that's where all basic concept of graphic design is lost. I think to deliver great advertisement on a national scale you do need a designer, not just with basic understanding of the platform they are working on, but with the understanding of how the brain works, what colours work and what keeps a customer coming back to a certain web page, just as a customer would return to a certain advertisement on the television or a magazine.
