The paper discusses three
visualization schemes Overview+Detail, Zooming and Focus+Context. The paper
gives detailed explanation of each category with example and figures. Further
the author refers to some empirical evaluation studies to compare the
effectiveness of each category. The authors infers few important points like, Overview+Detail
is better for understanding of text based documents whereas, focus+context
technique can provide better usability in terms of cosmetic effects.
Overview+Detail and zooming along with panning usually act as complementary.
The
author warns us that incorrectly implemented zooming techniques can be difficult
for user to understand and can hamper effectiveness of zooming. The article shows
how focus+context can be helpful for non-spatial representation. The working of
Mac OS X Dock is interesting read. The article also mentions cue based
techniques which can help to focus on information of interest. Overall I found
this article very useful and informative for visualization schemes.
