Visualization is both something that we do for others and something that we do internally within our minds. The creative,
do-it-for-others sense of visualization is covered in this chapter under other topics such as visual representation:
How do we “visualize” ideas for transmission to others? Most of the how-do-we-visualize questions had been answered
to the general satisfaction of the field until new, computer- associated questions arose. Revived interest now expresses
itself in terms of screen design, icon design, figureground, and similar look-of-the-tube issues. Friedhoff (1989)
has commented that “visualization, because of the computer, is emerging as a distinctive new discipline” (p. 16).
