ABSTRACT:
A data display method and apparatus for use in a vehicle, e.g. for use by the pilot of an aircraft, wherein each eye (EL, ER) of the user (23) is presented with a virtual image at infinity of a respective one of two largely identical displays (31L, 31R). By arranging for corresponding elements (33) of the two displays representative of a controller in the vehicle at a position accessible to the user to have a transverse positional disparity the virtual images of the corresponding elements appear to the user to fuse together to form a single image (I2) in a plane of the controller at a finite distance from the user within the vehicle thereby to facilitate operation of the controller by the user. Other corresponding elements (41, 43, 45, 47, 49) of the two displays (31L, 31R) will normally have no such positional disparity so that their virtual images fuse to present an image (I1) at infinity as in known binocular head-up display (HUD) systems. An aircraft pilot using a binocular HUD system is presented with an image of a control panel (37) in the aircraft to facilitate operation of the panel while using the HUD system.
