Not too long ago, the outcomes of a design process used to be in the form of a static medium. Today it is increasingly interactions – things that have a behavior. This not only fundamentally changes the design process, but also your life as a designer!
You are increasingly driving nonlinear processes, which are aiming towards a goal, that is not exactly defined at the beginning. The approach to this goal is very iterative through interactive sketches and by working with prototypes. Therefore you use new tools like vvvv and Arduino. And by working with prototypes, you’ll discover answers to questions that you haven’t even asked before.
