Visualisation of Large Networks in 3-D Space: Issues in Implementation and Experimental Evaluation

Yan Xiao Paul Milgram

Abstract Three dimensional visualisation has become a widespread scheme for helping users to access and manage large information network. In this report, various techniques for displaying depth information are reviewed, with an emphasis on stereoscopic displays. Input devices used to interact with a 3-D space are also examined. Issues in 3-D network visualisation are elicited from three viewpoints: psychological, task-related and implementational. Consideration of these issues leads to the design of a preliminary experimental programme for evaluating various network visu-alisation techniques.
