Human Centric AR&VR Display and Interface Technologies for Automobile

Abstract

& THE RECOGNITION OF Head Up Display (HUD) in the world is increasing as being adopted by the car manufacturers. With the development of advanced driving support systems and automatic driving technology, there are voices that “if these systems become widespread, HUD may not be necessary.” In response to these opinions, we consider that “the importance of HUD, which is the basis of human-machine interface (HMI).” In this special section, we focus on the HUD and automatic driving technologies as human centric technologies in addition to the mechanism and features of HUD that is the basis of HMI. The article “Requirements and System Aspects of AR-Head-Up Displays” by K. Blankenbach describes the requirements engineering for Augmented-Reality HUDs (AR-HUDs) and provides proposals to solve issues encountered in moving from conventional HUDs to AR-HUDs. The article “The Future of Holographic HeadUp Display,” by Philippe Coni et al., presented novel architecture using Holographic Optical Elements. This technology removes the need of complex optics, while offering a large field of view and a large eye-box, for a better user experience. The article “Mitigating Driver’s Distraction: Automotive Head-Up Display and Gesture Recognition System,” by R. Lagoo, et al., presented a novel HUD system which utilizes gesture recognition for direct manipulation of the visual interface. The HUD is evaluated in contrast to a typical Head-Down Display system by 20 users in a high-fidelity virtual reality (VR) driving simulator. The paper overall presents the system design challenges and user evaluation results. The article “Multi-Mirror Array Optics for Augmented Reality Devices in Automotive Applications,” by Tomoya Tsuruyama et al., presents novel optical AR system using multimirror array (MMA) optics for AR devices. MMA optics are compact optics used for constructing augmented reality devices. They prototype a wearable display with MMA optics. By using an MMA, they were able to make a wearable display that resembles conventional eyeglasses. They also used a Fresnel reflector to make a prototype wide field-of-view (FOV) combiner for HUDs. The article “Phase Only Holographic Head-Up Display without Zero-Order Diffraction Light for Automobiles,” by Yoshitomo Isomae et al., introduces a phase only holographic head up display without zero-order diffraction light for automobiles. Zero-order diffraction light degrades the quality of reconstructed images by overlapping with them. Hence, zero-order diffraction light Digital Object Identifier 10.1109/MCE.2019.2923900
