An Innovative Method for Presentation of Target Imagery to Human Observers in a Simulated Operational Environment

Abstract

Presenting observers with single frames of electronically gathered images of a scene denies the natural variability of signal and noise as they change across time. We discuss a methodology that preserves the temporal fluctuations of signal and noise: thus faithfully representing the images produced by fielded hardware for use as laboratory perception study stimuli. Camouflaged military targets imaged by a 1st Generation Forward Looking Infrared (FLIR) system, were presented to observers in a simulated operational environment. Analog FLIR imagery from a Tube-launched Optically tracked Wire-guided (TOW) sight was digitized and looped to create a dynamic presentation. A test bed was designed to present the images and collect human performance data on a single desktop computer. The performance measures were time to detection/identification and indication of the Visible Center of Mass of the targets. These data were scored using the Hit and Kill criteria from the appropriate military field manuals.
