The left panel shows the motion of the field and the stimulus relative to the retina. A retinal landmark is indicated by the white diamond. The right panel indicates how the field and stimulus are perceived to move as per the model in the supplementary discussion section. Settings: field: gain = 1, angle = 200; stimulus: gain = 2, angle = 160. In this simulation, the field and the stimulus are moving in different directions relative to each other, but both are close to a direction that is consistent with eye motion. The field has a rate of two and the stimulus has a rate of three times the eye motion. This corresponds to percepts reported for these stimulus parameters in earlier experiments not reported here.
