I will call these categories information software, manipulation software, and communication software. A person uses information software to construct and manipulate a model that is internal to the mind—a mental representation of information. Thus, this paper will simply treat communication software as manipulation software and information software glued together, and mention it no further. We’ve seen how graphic design can improve software, but how can software improve graphic design? Information software design, then, is the design of context-sensitive information graphics.
