Fisheye views are well-known visualisation techniques that provide a sense of global context as well as local detail. We have developed a prototype system that differs from traditional fisheye views in two ways. First, the user can create, edit, and move objects in the fisheye workspace. Second, our system is groupware, so several people can see and manipulate the data at the same time, using individual focal points. These differences raise usability questions concerning interactive fisheye views for groupware. These include a user's difficulty in maintaining layout fidelity as objects and focal points change, and the difficulty of showing where others are working and what they can see. INTRODUCTION Fisheye visualisations typically distort a two-dimensional space to provide the viewer with both a high-level overview of the data and fine detail around a particular location. Generally, fisheye views are look-only displays used at a single workstation: the user can move their focal poin...
