Peripheral vision guidance display
 A display is disclosed for indicating in the peripheral vision of a viewer the deviation between the actual position of a target and a reference position such as an aiming point. Light sources are arranged around a common circle which is of a particular size such that when viewed from a particular distance, the viewer sees the display by peripheral vision. There are two sets of light sources, one of which indicates the azimuth and elevation deviations of the target from the aiming point and the other of which may be used to indicate range. The direction of azimuth and elevation deviation is indicated by flashing selected light sources around the circle and the magnitude of deviation is indicated by flashing those light sources at a flash rate indicative of the magnitude. Range is indicated by causing the second set of light sources around the circle to illuminate upon attainment by the target of a certain range.
