Abstract
The report is a review of the helmet mounted display (HMD) literature, and was undertaken in order to understand the main issues and concerns involved in designing HMD systems for dismounted soldiers. Because there is such a large amount of published research on HMDs, this report is not an exhaustive review; rather, it is a summary of the main areas of current importance for HMD research. The main questions addressed in the HMD literature and summarized in this review centre around several themes: - should we be using monocular, biocular, or binocular HMDs? - should we be using cathode ray tube (CRT) or liquid crystal display (LCD) image sources? - at what point should we sacrifice resolution for field of view (FOV); - can we use colour effectively in HMDs? - how can we best use symbology on an HMD? - how do the size and weight of an HMD effect the user's centre of gravity (COG)? - how is situational awareness (SA) effected by wearing an HMD? There are many design choices to be made when creating HMD systems, and an understanding of the most pertinent issues, as well as current technological limitations, is extremely important. Presently, there is no absolute answer to the question of which HMD configuration is definitely best. Rather, each system must be designed with specific tasks, objectives, and environments of use in mind.
