Difictive colour vision can impede information acquisition form redundantly colour-Coded video displays

摘要: Earlier findings showed that redundant colour coding decreased response times and reduced errors in carrying out various tasks required information acquisition from the video desplay of an electronic flight instrument system. The results this experiment observers with defective vision have slower higher error rates than normal for some their performance is similar to colour-normal observrers a monochrome display. Howerver, they were not disadvantaged when blue was used code thae target feature. Protanopes shown be especiall responding red ‘fail’ message.
