弹出窗口透明度对信息判读绩效影响研究

Objective To explore the effect of pop-up window transparency on synthetical judgment performance of both pop-up window(foreground) information and background information. Methods (1) First obtain the distribution of pop-up window transparency under following conditions by the method of adjustment: the visible critical point of foreground information, the clearest point of synthetical information, the visible critical point of background information. And then pick up corresponding transparency levels. (2) Carry out the experiment on the basis of the selected levels. Results Reaction time was significantly influenced by pop-up window transparency no matter it was red, blue or black window; while accuracy was significantly influenced by pop-up window transparency when it came to black window．Conclusion As for red, blue and black pop-up windows include green characters, the transparency to provide both foreground information and background information ranges from 7% to 66%; and the optimum transparency for synthetical information is 24%-35%, 25%-35% and 25%-37%.
