Crawford, Robyn L., Toms, Mona L. and Wilson, Denise L. (1991): Effects of Display Luminance on the Recognition of Color Symbols on Similar Color Backgrounds. In: Proceedings of the Human Factors Society 35th Annual Meeting 1991. pp. 1466-1470.

“This study examined the effects of display luminance on the ability of human observers to recognize color symbols displayed against similar color backgrounds. The Signal Detection paradigm was utilized and subject sensitivity, as measured by d', was the primary measure of interest. The symbol colors were red, green, and blue. Background colors were .01 to .07 1976 CIE/UCS units distant from the symbol color. Luminance levels ranged from 11.85 cd/m{squared} to 127.25 cd/m{squared}. The symbols were presented on a cathode ray tube (CRT) under ambient lighting of two lux. Display luminance was found to affect subject sensitivity, d', as a function of symbol-background color combination. The results imply that display luminance for the presentation of blue symbology on bluish backgrounds is optimal at 19 cd/m{squared}. For the red and green symbol-background conditions, display luminance between 56 and 93 cd/m{squared} yields the best performance.”

Wilson, Denise L., Kuperman, Gilbert G., Crawford, Robyn L. and Perez, William A. (1988): Artificial Intelligence (AI) System Interface Attributes: Survey and Analyses. In: Proceedings of the Human Factors Society 32nd Annual Meeting 1988. pp. 1036-1040.

“This study represents a first phase in the design of a human factors tool for artificial intelligence (AI) system assessment. Desirable attributes of AI interfaces were identified as a result of a review of the literature. A questionnaire was developed where explicit definitions were presented for 17 selected attributes. Nineteen AI system developers rated the attributes under four different context conditions: (1) no context (i.e., general application); (2) a bomber crew system; (3) a command and control station; and (4) an intelligence analyst position. Examination of the ratings showed that attributes pertaining to tasks which impose a high level of time stress received the highest ratings of importance. The ratings data were subjected to Multidimensional Scaling (MDS) analyses where the following dimensions were determined: (1) tasks performed principally by the system versus tasks requiring system-human communication; and (2) system attributes that principally require algorithmic interpretation versus those that require a high level of AI capabilities.”
