It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

McClain, James E. (1989): Hue and Disparity Interactions in Advanced Stereoscopic Aircraft Displays. In: Proceedings of the Human Factors Society 33rd Annual Meeting 1989. pp. 1422-1426.

With the increased complexity of aircraft systems and their environment, 3-D stereoscopic system/control displays will offer great advantage over conventional two-dimensional (2-D) displays by presenting information more consistent with the pilot's 3-D perceptual experience and stereotypes. For such displays the interaction of Chromostereopsis (perceived depth created by hues) and stereopsis (depth effect created by disparity between the left and right visual fields of the observer) is important. The purpose of this research is to evaluate the interaction of chromostereopsis and artificially stimulated stereopsis on a stereoscopic CRT by determining the level of accuracy with which subjects can properly interpret the relative depth differences of adjacent symbols containing one of a combination of six levels of hue and seven stereoscopic disparities. This research demonstrated that hue, disparity, and the interaction of hue and disparity significantly influenced one's perception of depth on a stereoscopic monitor and that caution should be exercised by the stereoscopic 3-D display format designer when choosing hues to represent images located in close proximity on a stereoscopic display.

Zenyuh, John P., Reising, John M., McClain, James E., Barbato, Diana J. and Hartsock, David C. (1987): Advanced Head-Up Display (HUD) Symbology: Aiding Unusual Attitude Recovery. In: Proceedings of the Human Factors Society 31st Annual Meeting 1987. pp. 1067-1071.

The head-up displays (HUD's) of today's fighter aircraft present numerous symbology formats to the pilot which are essential for successful performance of a variety of flight tasks from navigation to weapons delivery. One common element in all of these formats is the pitch ladder, designed to provide the pilot with aircraft attitude even in the absence of external visual cues. Unlike the head down attitude director indicator (ADI), the HUD pitch ladder's intent is to aid the pilot in recovering from an unusual attitude while staying head-up. The purpose of this research was to compare the relative effectiveness of two changes to current pitch ladder symbology designed to enhance the pilot's ability to recover from unusual attitudes -- the use of angled pitch bars versus standard straight pitch bars and multicolor versus the standard monochromatic symbology. The results showed that, in extreme unusual attitudes, the use of both the angled pitch bars and color contributed to better flight performance. In the non-extreme attitudes however, where the horizon line is always visible, the standard symbology was sufficient for recovery.
