Abstract
Human perception tests have been performed by Night Vision Electronic Sensor Directorate (NVESD) addressing the process of searching an image with the intent of detecting a target of military importance. Experiments were performed using both real thermal imagery and synthetic imagery generated using 'Paint the Night' simulation. It was demonstrated that trained observers acquire targets much more quickly than previously expected. This insight was gained by changing the instructions the observers were given for the test. Rather than telling the observers that they were being timed, the observers were given a time limit, as short as 3 seconds. When time limited, the observers found targets quicker. Although false alarms per second increased with the shorter time limits, the ratio of false alarms to detected targets did not increase. A modification to the traditional NVESD search model has been developed and incorporated into Army war games and simulations.
