Perceptual Limitations of Peripherally Displayed Colors on CRTs
Abstract
Cathode ray tubes are currently used in aircraft cockpits to relay important color coded information necessary for mission completion and pilot survival. Color CRTs presently used are as large as 6 inch x 6 inch, but are projected to increase in size until the all glass cockpit is achieved. As the display gets larger, peripheral vision may be relied upon even more heavily. Peripheral vision is also important in present situations involving more than one CRT display used in a row, and especially when the pilot is in a head-up mode. The research in this report dealt with a subject's ability to recognize in their peripheral vision the three primary colors, blue, green, and red, on a cathode ray tube (CRT) with all three guns adjusted to achieve equal luminance. Data for various subject psychological states (normal, stressed, and relaxed) was collected. Percent error (e.g., how many times red was perceived as green or blue) was recorded for each state and color. A second performance measure, visual field dimension (e.g., degrees off of fovea where the color of the circle was correctly perceived) along the x-axis, was also collected for each color and psychological state.
