TL;DR
Distortion oriented displays are proposed, which employ magnification lenses and fisheye view techniques, to show global context and local detail within a single window, providing both peripheral and detailed awareness of other participants’ actions.
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 propose distortion-oriented displays 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 prototypes are presented as examples of groupware distortion-oriented displays: the fisheye text viewer, the offset lens, and the head-up lens.

A study of shared editor use is discussed which suggests that awareness information provided and exploited passively through the shared workspace, allows users to move smoothly between close and loose collaboration, and to assign and coordinate work dynamically.

Workspace awareness for groupware

The results show that users of a direct-manipulation interface and a menu-based interface did not differ in the total amount of time used to perform a task, but there are significant interactions between task familiarity, instructions, and the type of interface, indicating that Norman's model may not hold under all conditions.
