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
\fIworkspace awareness\fR-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 propose \fIdistortion oriented displays\fR
as a novel way of providing this awareness. These displays, which employ
magnification lenses and fisheye view techniques, show global context and
local detail within a single window, providing both peripheral and detailed
awareness of other participants' actions. Three prototype inventions are
presented as examples of groupware distortion-oriented displays: the
fisheye text viewer, the offset lens, and the Ihead-up lens.
