Modeling Human Performance with Environmental Stressors: A Case Study of the Effect of Vehicle Motion

Abstract

Human performance modeling tools are used to predict mission performance as a function of human performance. The U.S. Army Research Laboratory has developed a human performance modeling tool, the Improved Performance Research Integration Tool (IMPRINT), for investigation of the impact on a Soldier's performance when the Soldier subjected to environmental stressors such as heat and cold. IMPRINT has the capability to create user-defined stressors to study the stressors' effect on human performance and therefore system performance. This case study used data from literature to create a user-defined stressor in IMPRINT to predict the effect of riding in a moving vehicle on task time and performance. This capability can provide useful information to system designers.
