Abstract:
1. Head-up apparatus for a vehicle for which a navigational path from a current location of the vehicle to a desired destination location of the vehicle has been computed, the head-up apparatus comprising at least one computer, and at least one virtual cable display device controllable by the at least one computer, the at least one virtual cable display device and the at least one computer being configured in such a way that when the at least one virtual cable display device is controlled by the at least one computer, there is displayed to an observer within the vehicle, volumetrically and with continuous depth, a virtual optical image that a) appears to the observer to be a three-dimensional cable that is higher than the head of the observer and appears to be extending away from the observer in three dimensions above at least one roadway along the computed navigational path, b) is displayed to the observer with an optic flow that is consistent with the optic flow of the landscape when the vehicle is moving, thereby causing the cable to appear to remain in a substantially stationary position above both straight and curved sections of the roadway even when the vehicle is moving along those straight and curved sections of the roadway, c) is displayed with at least the depth cue of stereoscopic disparity and the depth cue of motion parallax induced by head movements of the observer, and d) is displayed in such a way that in response to the vehicle being driven along roadways above which the cable appears to extend, the vehicle is caused to arrive at the destination location.
