We have been studying two-dimensional displays using afterimages caused by saccadic eye movement. We need to investigate the spatial and temporal characters of saccade-induced afterimages, to develop a design theory on these displays. However, there have been few studies on temporal characters. We, therefore, tried to determine how long afterimages induced by saccades persisted. Our results indicate that the duration of saccade-induced afterimages last as long as that of afterimages induced by a moving illuminant with the eyes fixed, although various perceptional features are suppressed around the time of the saccade. Our results also suggest that saccade-induced afterimages can be grouped with other visual stimuli after the shape of the afterimage is formed.
