Cleotilde Gonzalez While waiting for the Visual Interaction Design (VID) meeting in C H I '94, I looked at the screen at the title: 'Visual Interaction Design', and wondered, ' W h y do we use the word interaction and not internee or dialogue?' The word interface is almost universally used, and everybody knows what an interface is. Dialogue may also be a good word, and it c o m m o n l y replaces the word interface in several publications. Interaction seemed intuitively a good word to describe what visual designers do, but what is the difference between interaction, interface, and dialogue? I thought about these concepts during Loretta Staples' presenta- its o f a system, determines where the system ends and where the environment starts, and it is the medium to c o m m u nicate from the environment to the system and from the system to the environment. As visual designers we should ask ourselves: do we design the m e d i u m to communicate or the actual communication process? T h e word dialogue is c o m m o n in h u m a n communication.
