The significant format by highlight validity interaction showed that there was little difference in response time to both current and reformatted displays when the highlight validity was applied however, under the non or invalid highlight conditions, search times were faster with reformatted displays. Responses to valid applications of highlight were significantly faster than responses to non or invalidly highlighted applications. A 2x2x3 within-subjects analysis of variance found that search times were faster for items in reformatted displays than for current displays. A study manipulating these variables was conducted using realistic, complex Space Shuttle information displays. Rudisill, Marianneĭisplay format and highlight validity were shown to affect visual display search performance however, these studies were conducted on small, artificial displays of alphanumeric stimuli. The results suggested that differences between highlight and object colors enhance perceived glossiness and that perceived glossiness does not depend on naturalness of color combination for highlights and objects.ĭisplay format, highlight validity, and highlight method: Their effects on search performanceĭonner, Kimberly A. Objects with some unnatural combinations of highlight and object colors were perceived to be as glossy as those with natural color combinations. Objects were perceived as glossier when the highlight color was different from the object color than when they were the same. Four colors were used for objects and highlights. The color coordinates of objects and highlights were varied while luminance of each pixel was unchanged. Ten participants rated glossiness of object images. The effect of highlight and object colors on perception of glossiness was examined. Difference between highlight and object colors enhances glossiness.
