Abstract : The underlying principle guiding the research is that in many display-interpretation tasks, the limiting factor is the short-term visual memory of the operator. Specifically, in the time interval when the display is off, the visual image of the display fades. It is shown that this fading may be combatted by increasing the display persistence and thereby shortening the off interval; by presentation of successive display fields; by perceptual speed-up of successive display fields; and by display aiding in the form of marked trails. Suggestions are made for the possibility of improvement of operational displays.
