Helmet-Mounted Area-of-Interest Display

This report describes the results of a design study for a helmet- mounted display (HMD) for use as an area of interest (AOI) for the Display for Advanced Research and Training (DART). The objective of the research was to investigate alternative optical approaches for building a helmet-mounted area of interest (HMAOI) for the DART and to recommend the optimal approach based on performance and cost tradeoffs. The experiment examined several system design problems: the design of an HMD eyepiece with minimal obtrusiveness, visual blending of the HMD imagery with the projected imagery, and timing and perspective issues relating to the computer-generated imagery presented by both the HMD and the projection display.
