Real-time, large-depth holographic 3D head-up display: selected aspects

Abstract

Today’s state-of-the-art automotive head-up displays (HUD) possess single- or double layer focal planes that limit the observers’ eye focus to these planes when crucial information is shown. Other visual 3D cues such as motion parallax also suffer from this limitation. The resulting viewing experience contradicts the natural way of viewing during driving or interaction, when alerts and hints should appear at the correct projection depth where real objects of interest are located. Here we present a real-time holographic HUD with continuous depth that supports the intuitive and natural way of viewing and interacting with virtual environments outside and inside the car. We demonstrate full-color, 3D real-time encoding within a field-of-view of ${5}^\circ \times {3}^\circ$.
