Session 4
Victor L. Wallace · 1977
The following paragraph was distributed to participants in advance:We define "conversation" as a sequence of goal-directed interactions between man and machine. Ergonomics refers to the design of the working environment in which the "conversation" takes place. Ideally the design permits the man to focus on the intent and meaning of the (two-way) communication, thereby transcending the elemental output and input capabilities (Session 3). Unfortunately, the ideal is rarely achieved. This session will be concerned with the factors which promote the conversational quality of graphic interaction. We will seek to organize, exploit, and extend this knowledge for the benefit of designers--and ultimately users--of conversational graphic systems.
