The aim of this study was to assess what drives gender-based differences in the experience
of cybersickness within virtual environments. In general, those who have studied …

The technology underlying night vision goggles (NVGs) enhances human ability to operate
in dark and low-light conditions. However, NVG-aided vision is limited relative to daylight …

Helmet-mounted displays (HMDs) have been in development since the 1960s. Now, almost
five decades later, the technology has improved significantly; HMDs have made some …

The Warfighter in the modern battlespace has a predetermined, but ever-changing, set of
tasks that must be performed. Performance on these tasks is affected strongly by the amount …

Under natural viewing conditions, the accommodation and vergence systems adjust the
focus and the binocular alignment of the eyes in response to changes in viewing distance …

A number of currently proposed helmet-mounted display (HMD) designs relocate image
intensification (I 2) tubes to the sides of the helmet. Such a design approach induces a visual …

Two separate experiments examined user performance and viewer discomfort during virtual
precision alignment tasks while viewing a stereoscopic 3D (S3D) display. In both …

A flight study was conducted to assess the impact of hyperstereopsis on helicopter handling
proficiency, workload and pilot acceptance. Three pilots with varying levels of night vision …

The modification of binocular cues in some stereoscopic-display designs potentially alters
apparent distances. Although further work is needed to completely clarify the determinants of …

Visually coupled systems such as helmet mounted displays are designed to improve aircrew
situational awareness by providing timely flight, targeting and other information overlaid on …
