Abstract (en)

A visual display has a flicker frequency which is higher than a critical flicker fusion frequency for central vision so that, when viewed directly, no flicker is discernable. The flicker frequency is less than a critical flicker fusion frequency for peripheral vision so that flicker is at least subliminally apparent in the peripheral vision in order to attract attention to the display. A suitable flicker frequency for many purposes is 75 Hz. <IMAGE>
