Abstract
Visual information overload is a serious problem for users of geographical information systems (GIS), or other applications with complex displays, where the requirements of access to both local detail and wider context conflict. This problem is compounded for users of real-time groupware applications by the need to maintain awareness information about other users and their actions. In this paper, we describe our use of fisheye views to assist with visual information overload management in GROUPARC, a lightweight real-time groupware application for browsing and annotating GIS data. 1 Introduction Our capacity for assimilating complex visual displays, such as GIS data, is limited. The phenomenon of visual information overload occurs when this capacity is exceeded, typically resulting in confusion, oversight and errors of interpretation. The ability to focus on regions of interest in detail, while retaining awareness of context, is necessary if users are to visualise and comprehe...
