It might be said that this book points in the direction of our society's current renewed emphasis on the human. In order to make dialogues that people will use, the systems designer should become aware of the user, who is not a machine but a human being, and become aware, too, of the user's particular needs, sensitivities, and psychological reactions to conversing with a computer. For as Martin states in his introduction, "the future growth of the computer industry and the acceptance of computer methods will depend largely on the successful establishment of effective man-machine communications."
