Abstract
The use of a camera system on weapons, in combination with a Helmet Mounted Display (HMD), that enables a soldier to observe, detect, and engage targets from behind cover without exposing their head or upper body to enemy fire, is being widely considered in many NATO soldier modernization programs. To better understand the effect of certain technology characteristics on target detection performance this study empirically investigated the effect of varying image field of view and image resolution (Experiment A), the use of digital image alteration to improve target saliency (Experiment B), and the use of digital magnification (Experiment C). Experiment A: The results of Experiment A indicated that regardless of resolution, participants spent less time searching for targets, participants were more confident in their performance, and were more successful at detecting targets with larger fields of view. Although participants tended to spend a longer amount of time with the higher resolution images, results from this experiment indicated that target detection performance was significantly higher at horizontal resolutions of 640 pixels and above. Experiment B: By manipulating the image luminance, colour curve, gray scale, contrast and gamma levels, surveillance scene images were digitally altered in Experiment B to investigate whether target detection performance could be enhanced by making the target more salient in the scene. Results from this experiment indicated that participan
