Ergonomics Studies of Using Color and Flashing as Redundant Highlighting Codes in Graph Displays

The experiment was conducted to investigate the visual performance of using color and flashing as redundant highlighting codes in graph displays. Correct rate and reaction time were analyzed. The results were as follows: color or flashing as a kind of highlighting code, has a significant positive effect on the performance of visual search;color and flashing as redundant highlighting codes,no significant positive effect on the performance of visual search.
