In this short video by Toscanalab Don Norman explains what is expected of a person wanting to become an interaction designer. As Norman puts it, there are four main areas of focus that one must become adept in to fulfill this ambition. A solid understanding of technology and its advantages and limitations in relation to both hardware and software are expected by industry but not without a high degree artistic insight also.
The third and fourth characteristics of an interaction designer Norman goes on to say are psychology and business. “A great interaction designer is actually an applied social scientist because what you are trying to do is interact with people and maybe change peoples understanding, peoples behavior . . . . you must understand what drives business, what causes customers to purchase things . . .”
