We explore the feasibility of implementing stereo-pair 3D images with an eye-tracking-based light-field display and actual head-up display optics for automotive applications. We translate the driver’s eye position into the virtual eyebox plane via a “light-weight” equation to replace the actual optics with an effective lens model, and we implement a light-field-rendering algorithm using the model-processed eye-tracking data. Furthermore, our experimental results with a prototype closely match our ray-tracing simulations in terms of designed viewing conditions and low-crosstalk margin width. The prototype successfully delivers virtual images with a field of view of 10° ´ 5° and static crosstalk of <1.5％.
