Abstract
Desktop conferencing systems are now moving away from strict view-sharing
and towards relaxed "what-you-see-is-what-I-see" (relaxed-WYSIWIS)
interfaces, where distributed participants in a real time session can
view different parts of a shared visual workspace. As with strict
view-sharing, people using relaxed-WYSIWIS require a sense of
workspace awareness -the up-to-the-minute knowledge about
another person's interactions with the shared workspace. The problem
is deciding how to provide a user with an appropriate level of
awareness of what other participants are doing when they are working in
different areas of the workspace. In this paper, we summarize requirements
for workspace awareness, identify problems with existing groupware
solutions, and propose as a replacement fisheye views that show
both global context and local detail within a single window. Within
groupware, these displays provide peripheral awareness of other participants
by showing their position and actions in the global context. As well,
detailed awareness is provided by assigning multiple focal points to
each participant, and by magnifying the area around everyone's work
to highlight all details of their interactions. Concepts are illustrated
in two groupware prototypes: a fisheye graph browser, and a fisheye
viewer for text documents.
