Previous research shows that participants exhibit impairments in spatial memory while experiencing various types of spatial disorientation (SD) in a laboratory environment. With regard to aviation-based SD, a pilot's ability to think his/her way out of a dangerous situation may be impaired when disoriented. The present study assessed the effects of SD on cognitive functioning during simulated flight. Thirty-six UH-60 aviators participated in the study. Participants were asked to perform ...
A number of currently proposed helmet-mounted display (HMD) designs relocate image intensification (I2) tubes to the sides of the helmet. Such a design approach induces a visual condition referred to as hyperstereo vision (or hyperstereopsis). This condition manifests itself to the user as an exaggerated sense of depth perception, causing near- to mid-range objects to appear closer than they actually are. Hyperstereopsis is potentially a major concern for helicopter operations ...
