Visualising uncertainty in aircraft cockpits : Is icon degradation an appropriate visualisation form

Visualising uncertainty information has been a research area for the past decade or so, and this thesis contains the results of an experiment that examines whether prior research on icon degradation for showing uncertainty can be used in a simulated aircraft cockpit environment. Using icon degradati...

description Visualising uncertainty information has been a research area for the past decade or so, and this thesis contains the results of an experiment that examines whether prior research on icon degradation for showing uncertainty can be used in a simulated aircraft cockpit environment.

Two icon sets using icon degradation were taken from prior research, and one new icon set using shape change and colour change was created for comparison.
