ABSTRACT
As a social scientist trained both in psychology and anthropology, I was one of these “experiments.” I began to serve the design process in 1982. In the 1980s I played the role of the human factors practitioner, or “user advocate.” My role was to know the user and to translate that knowing into principles and prescriptions that the designers with whom I worked could understand and use. We called this the user-centered design process. As I learned ways to help make products and information systems more usable, I also studied the designers, especially the ways they visually communicated with each other.
