"Interactive designer: Generally speaking, all designers are interactive designers since users work with an interface with the object they make. However, an interactive designer focuses on not only the user interface, but also the human computer interaction, and may have a strong background in heuristics or psychology and cognitive science."
— Jason Tselentis, trying to define the interactive designer in “The Graphic Designer’s Electronic-Media Manual”.
