Paper Abstract

We have investigated whether reading is adversely affected by the flicker of VDTs. We use 60 Hz flicker for our low frequency because it is the standard used in most computer monitors, and 500 Hz for our upper boundary because it provides nearly constant presentation. Sixty hertz flicker results in 16.67 ms of dead time after every screen write. Therefore, there is no usable information at the fixation point for an average of 8.33 ms following a saccadic eye movement. We hypothesized that the visual system might have to wait for text to become available after each saccade, slowing reading speed. The 500 Hz condition allows 2 ms of dead time with an average wait of 1 ms.
