MISREGISTRATION IN COLOR ADDITIVE DISPLAYS.
Abstract
The relationship between misregistration in color additive displays and viewer performance was studied. In the first experiment simple geometric forms were pre sented, one at a time, and the subject's response times were recorded. A progressive increase in reaction time was found from 65 per cent misregistration to 100 per cent misregistration. The second experiment was designed to be more generalizable to operational displays. Thirty-six alphanumeric symbols were presented simultaneously in seven colors with an additive color projector similar to those used in command and control systems. Using an accuracy-speed composite score as a performance measure, results similar to the first experiment were obtained. The results indicate that for ideal conditions misregistration should not exceed 65 per cent of stroke width. This is not to say, however, that misregistration up to 65 per cent can be tolerated without additional considerations. It is quite likely that for operational conditions, involving prolonged observation and stress, a more stringent criterion should be employed. (Author)
