Abstract: Head-mounted displays (HMDs) are a potentially viable technology for presentation of the "out-the-window" (OTW) scene for Army aviation simulators. As part of an effort to evaluate their suitability for Army aviation, a preliminary assessment of three Kaiser ProView (Trademark) HMDs was conducted during a simulation exercise at the U.S. Army Aviation Test Bed, Fort Rucker, Alabama. The assessment evaluated the fit, retention, and visual display characteristics of the HMDs. The method used to assess the HMDs included aviator responses to a usability survey, statistical correlation of survey responses with head measurements obtained from each aviator, observation of aviator performance during their missions, and post-mission interviews. Most of the fit, retention, and visual display characteristics of the HMDs were judged to be acceptable by the Army aviators. Suitability of the HMDs would be improved by an increase in field of view and the use of lightweight electrical cables to minimize restriction of head movement and potential for pressure-induced hot spots.
