Helmet-Mounted Display Computer Model and Research Visualization Tool

Abstract

As the Army increases its reliance upon helmet mounted displays (HMDs) or head-up displays (HUDs), it is paramount that displays are developed that meet the operational needs of the warfighter. During the development cycle, questions always arise concerning the operational requirements of the HMD. These include questions concerning luminance, contrast, color and resolution. To provide intelligent answers to these operational questions, a method has been devised to evaluate these issues. Integral to this method is a HMD simulation model. The model allows for contrast correct visualizations of see-through imagery. The imagery consists of symbology/situational maps overlaid over natural backgrounds. Using visual psychophysical procedures, observers judge the quality of the symbology for a range of luminance and background conditions. The simulated images were analyzed and statistical correlates were developed that could relate to the observer's ratings. Metrics were developed that could help predict the operational luminance requirements for HMD or HUD symbology.
