Head-mounted display (HMD) assessment for tracked vehicles

Providing the warfighter with Head or Helmet Mounted Displays (HMDs) while in tracked vehicles provides a means to visually maintain access to systems information while in a high vibration environment. The high vibration and unique environment of military tracked and turreted vehicles impact the ability to distinctly see certain information on an HMD, especially small font size or graphics and information that requires long fixation (staring), rather than a brief or peripheral glance. The military and commercial use of HMDs was compiled from market research, market trends, and user feedback. Lessons learned from previous military and commercial use of HMD products were derived to determine the feasibility of HMDs use in the high vibration and the unique environments of tracked vehicles. The results are summarized into factors that determine HMD features which must be specified for successful implementation.
