Abstract: A display system conveys vehicle guidance information in the peripheral field of view of the user by the movement of ambient symbology that is not representational of either symbols or physical objects, and does not require any optics for the purpose of representing the display within the focal range of the eye. The ambient symbology is presented outside the central 30 degrees of the forward field of view of the user, and appeals to the ambient or peripheral mode of processing visual information, in contrast to previous displays which have been designed for focal modes of visual processing.
