Abstract
The browsing of two dimensional images can be found in a large number of
applications. When the image to be viewed is much larger than the screen
available, a two dimensional browser has to be provided to allow users to
access all parts of the image. We show the diversity of tasks and systems
available and the need for 2D browser design guidelines. In the context
of a microscope image browser, we investigate one common technique
consisting of a global view of the whole image, coupled to a detailed,
magnified view of part of the image. In particular we look at the
benefits of providing an intermediate view when the detail-to-overview
ratio is high. An experiment showed that users performance significantly
degrades when no intermediate view is provided for a detail-to-overview
ratio over 20:1. Our experience is also a good example of a real world
application for which added features and added hardware need to be
justified.
