Human Centric AR&VR Display and
Interface Technologies for Automobile

& 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
