Patent ID: 7719484

Claim:
A vehicle simulator for a human user for simulating a real vehicle having an actual head-up display that displays a real head up display image and has optical characteristics that limit viewing of the real head up display image from some points of view within the real vehicle, said simulator comprising: a tracking apparatus providing a time-dependent signal relatable to or representative of a position of an eye of the user; an image system forming a visual image viewable by the user, said image including a scene representing a simulated out-the-window view outside the vehicle and a simulated head-up display image simulating the real head up display image and superposed on said scene; said image system generating said simulated head-up display image using the signal provided by the tracking apparatus so that the simulated head-up display image displayed to the user is limited when the tracking apparatus signal indicates that the user is viewing the simulated head-up display from a point of view wherein the optical characteristics of the actual head-up display in the real vehicle limit viewing of the real head up display image thereof.
