SUPPLEMENTARY NOTESThis paper was originally published in the 2006 Proceedings of the Human Factors and Ergonomics Society conference. ABSTRACTAs monocular head-mounted displays (HMDs) are introduced into existing flight simulators for training and mission rehearsal it will be important to determine whether binocular rivalry affects the visibility of HMD presented symbology or the out-the-window (OTW) flight simulator display imagery. In the present study, we examined whether rivalry suppression could be objectively measured under conditions that simulated a monocular HMD and OTW display, and whether voluntary attention and moving imagery influenced the strength of rivalry suppression. The results indicated that strength of suppression under these conditions was less than that found under classic dichoptic viewing conditions, and that attention had little influence on performance.

Binocular Rivalry and Head-Worn Displays

“…This difference in results between the Blake and Boothroyd (1985) study and the Winterbottom, Patterson, Covas, et al (2006) and studies is likely attributable to different methodologies.…”

“…In both studies, the binocularly viewed outdoor scene exerted a suppressive effect on the monocular imagery but not vice versa. Winterbottom, Patterson, Covas, et al (2006) also found that directed visual attention to either the outdoor scene or the HWD symbology did not alter the occurrence of the rivalry.…”

“…However, as we discussed previously, Winterbottom, Patterson, Covas, et al (2006) and Winterbottom, Patterson, Pierce, et al (2006) reported that binocular rivalry continues to exert some influence when monocularly viewed symbology is superimposed on an outdoor scene that is viewed binocularly. This difference in results between the Blake and Boothroyd (1985) study and the Winterbottom, Patterson, Covas, et al (2006) and studies is likely attributable to different methodologies.…”

“…Hakkinen (2004), for example, stated that the occurrence of rivalry with a monocular HWD results in an annoying and straining experience for the user. In military applications, binocular rivalry is suspected to contribute to the visual problems, noted previously, associated with the U.S. Army's Apache helicopter IHADSS (Behar et al, 1990) and to decrease the visibility of flight symbology in the U.S. Air Force JHMCS (Winterbottom, Patterson, Covas, Rogers, & Pierce, 2006;Winterbottom, Patterson, Pierce, & Taylor, 2006).…”

“…Using objective psychophysical procedures, Winterbottom, Patterson, Covas, et al (2006) and found that binocular rivalry was present during the viewing of a simulated semitransparent monocular HWD. These studies used flight database imagery (i.e., an outdoor scene) and simulated HWD symbology that were relevant to the training of U.S. Air Force pilots.…”
