As a community, human-computer information and
interface designers have tended to avoid use of
fisheyes, and multi-scale presentations with their
attendant distortion because of concern about how
this distortion may lead to confusion and
misinterpretation. On the other hand, for centuries,
hand-created information presentations have made
regular use of distortion to provide emphasis and
actually enhance readability. Is the lack of use in
computer presentations because thus far in our
computational uses of distortion we have failed to
provide adequate support that allows people to
comprehend the manner in which the information is
being presented? We describe a study about relative
difficulty in reading distortions that investigates the
effect of the use viewing cues such as the
cartographic grid and shading on people’s ability to
interpret distortions. We look at two interpretation
issues: whether people can locate the region of
magnification and whether people can read the
relative degree of magnification of these regions. We
present the findings of this study and a discussion of
its results.
