Color-Blindness Study: Color Discrimination on the TICCIT System.
Asay, Calvin S.; Schneider, Edward W.
The question studied whether the specific seven TICCIT system colors used within color coding schemes can be a source of confusion, or not seen at all, by the color-blind segment of target populations. Subjects were 11 color-blind and three normally sighted students at Brigham Young University. After a preliminary training exercise to acquaint the subjects with the TICCIT terminal, keyboard, and use of the systems's colors, subjects completed a color coding test which required them to match color coded responses with color stimuli. Students were then given a short questionnaire to assess color presentation preferences. A subject error in the test was defined as a color coding response different than the stimulus color given. Confusibility of the seven TICCIT system colors was determined by subject color coding errors tallied into a color combination matrix. Task and questionnaire results indicated confusion among color-blind subjects in green-yellow, white-cyan, and red-black color coding combinations, while normally sighted subjects had no real trouble with any of the combinations. In addition, color-blind students felt that color was desirable in instruction if used sparingly and logically. (CMV)
