Abstract

Visualisation is becoming increasingly important for understanding information, such as investigative data (for example: computing, medical and crime scene evidence) and analysis (for example: network capability assessment, data file reconstruction and planning scenarios). Investigative data visualisation is used to reconstruct a scene or item and is used to assist the viewer (who may well be a member of the general public with little or no understanding of the subject matter) to understand what is being presented. Analysis visualisations, on the other hand, are usually developed to review data, information and assess competing scenario hypotheses for those who usually have an understanding of the subject matter. Visualisation represents information that has been digitally recorded (for example: pictures, video and sound), hand written and/or spoken data, to show what may have, could have, did happen or is believed to have happened. That is why visualising data is an important development in the analysis and investigation realms, as visualisation explores the accuracies, inconsistencies and discrepancies of the collected data and information. This paper introduces some of the various graphical techniques and technology used to display digital information in a courtroom. The advantages and disadvantages involved in the implementation of this technology are also discussed. This paper is part one of a two part series that aims to describe the use of, and provide guidelines for, the use of graphical displays in courtrooms.
