Amount of Information Acquired by Reading Display Information Repeatedly

When a driver views the display device, there are two ways to read the information displayed: repeatedly diverting his attention to the display device for short periods of time or reading the information through, all at one time. The authors investigated differences in the amount of information retained for both of these reading methods by carrying out experiments indoors. This experiment showed that even when the amount of time that the subject was actually viewing the display was the same, the amount of data acquired by the subject from reading the display repeatedly was greater than the amount of information acquired by reading the display through at one time.
