Buxton, R. 2015 A scoping study for the design of a visual interface to convey complex critical infrastructure outage information. Lower Hutt, N.Z.: GNS Science. GNS Science report 2015/56 ii, 18 p.

Abstract: GNS Science has been undertaking research into interdependencies between critical infrastructure systems since 2010. Most of the model development work has concentrated on modelling techniques that allow the modellers to simulate infrastructure outages at a ''major component'' level. Previous prototypes have used conventional ''map style'' displays to represent the results of simulation runs. Whilst these portray the information for one critical network adequately, the map becomes visually confusing when several different critical infrastructure systems are needed to be displayed. This study aims to determine whether an alternative interface design could be utilised that could better convey the simulation outputs to the user. There are a number of interface design approaches that are encompassed in this prototype design. These include User Centred Design (UCD), Ecological Interface Design (EID) and Situational Awareness (SA). Initially it was thought a 3-D based interface would be a good path to take, however, this was quickly discarded on the basis of expected difficulties with possible user uptake. As a result, the proposed prototype composite visual interface has been developed. (auth)
