Bob Gratz and I began writing about technology in the late 1970s. Later, he would go on to be an active administrator at Texas State University, serving as a chair, dean, academic vicepresident, and assistant to the president. I designed one of the first graduate classes about human communication technology in the early 1980s, and I have continued to research and write about a fascinating area.

This book is about how humans communicate, and it examines the latest research about enduring issues related to human communication technology. These issues range from the nature of human information processing to humans' sense of reality. At the center of all these issues is how humans construct communication, and, in so doing, construct themselves, alone and together, and construct the world they inhabit.
