Paper Abstract

The Integrated Helmet and Display Sighting System (IHADSS) helmet-mounted display (HMD) has been flown for over a quarter of a century on the U.S. Army's AH-64 Apache Attack Helicopter. The aircraft's successful deployment in both peacetime and combat has validated the original design concept for the IHADSS HMD. During its 1970s development phase, a number of design issues were identified as having the potential of introducing visual perception problems for aviators. These issues include monocular design, monochromatic imagery, reduced field-of-view (FOV), sensor spectrum, reduced resolution (effective visual acuity), and displaced visual input eye point. From their diverse perspectives, a panel of four experts - an HMD researcher, a cognitive psychologist, a flight surgeon, and a veteran AH-64 aviator - discuss the impact of the design issues on visual perception and related performance.
