Some temporal characteristics of eye tracking.
The frequency of occurence and the latency of eye tracking determined by moving stimuli of different velocities (5, 10 and 15 degrees/s) and different durations (between 50 and 400 ms) were measured. The result was that eye movement can occur only if the duration of the stimulus exceeds a critical value. This value depends on the stimulus velocity. The difference between the latency of the movement and the critical duration of the stimulus however remains constant. This difference is interpreted as the time necessary for selecting and releasing the appropriate programme for eye movement.
