<title>Helmet-mounted display human factor engineering design issues: past, present, and future</title>

Abstract

An often overlooked area ofhelmet-mounted display (HMD) design is that of good human factors engineering. Systems which pass bench testing with flying colors can often fmd less enthusiastic acceptance during fielding when good human factors engineering principles are not adhered to throughout the design process. This paper addresses lessons learned on the fielding ofthe AH-64 Apache Integrated Helmet and Display Sight System (IHADSS) and the Aviator's Night Vision Imaging System (ANVIS). These lessons are used to develop guidance for future HMDs in such diverse areas as: user adjustments, anthropometry, fit and comfort, manpower and personnel requirements, and equipment compatibility.

Perceptual Issues in the Use of Head-Mounted Visual Displays

“…One important technological advance in recent years has been the development of wearable headmounted visual displays (HMDs) for military and commercial applications (e.g., Frey & Page, 2001;Licina, Rash, Mora, & Ledford, 1999). An HMD presents symbolic or pictorial information to the eyes of a user by way of one or two miniature visual displays, such as an aiming reticle or full-color imagery (Havig, Grigsby, Heft, LaCreta, & Post, 2001), mounted on the head via a helmet or other kind of arrangement.…”
