Paper Abstract

This paper addresses the human component of the human-machine interface and the effects of operational stressors on the user as a system operator. Discussions will strive to link operational stress factors to perception, cognition, and human performance errors and their implications for the design of helmet-mounted displays (HMDs). While many operational stressors can be self-imposed (e.g., fatigue, medication use and smoking), this discussion will focus on environment-related (external) stressors. Generally these factors are characteristics of an environment that require unique countermeasure development versus being under the direct control of the user. These include altitude, noise, vibration, thermal extremes and ambient lighting. Thus, it becomes incumbent upon the HMD designers to be cognizant of these environmental stressors and understand how the Soldier will perform when exposed to these conditions.
