Estimation of the Detection Performance of a Display.

Abstract

Signal detection performance is commonly described by Receiver Operating Characteristic (ROC) curves plotting the probability of signal detection (PD) versus the probability of false alarm (PFA) over a range of detection thresholds. This report describes a method for determining ROC curves for visual displays and presents results obtained from display evaluations. The visible displays discussed here will represent functions derived from a meaningless random noise waveform that has a particular controlled waveform added whenever a 'signal plus noise' message is to be displayed. The addition of signal will be detected by the change in visible patterns from a meaningless noise background to a significantly ordered pattern. The signal-to-noise ratios are the relative power in the signal and noise waveforms combined to create signal messages. (Author)
