Wearable near-eye displays for virtual and augmented reality (VR/AR) have seen enormous
growth in recent years. While researchers are exploiting a plethora of techniques to create …

The vergence-accommodation conflict (VAC) remains a major problem in head-mounted
displays for virtual and augmented reality (VR and AR). In this review, I discuss why this …

Holographic displays promise unprecedented capabilities for direct-view displays as well as
virtual and augmented reality applications. However, one of the biggest challenges for …

We present novel designs for virtual and augmented reality near-eye displays based on
phase-only holographic projection. Our approach is built on the principles of Fresnel …

Over the last few years, virtual reality (VR) has re-emerged as a technology that is now
feasible at low cost via inexpensive cellphone components. In particular, advances of high …

Lenses with tunable focal length play important roles in nature by hel** species avoid
predators and capture prey. Many practical devices mimic lens concept for imaging, sensing …

We propose near-eye light field displays that enable thin, lightweight head-mounted
displays (HMDs) capable of presenting nearly correct convergence, accommodation …

Conventional stereoscopic three-dimensional displays suffer from vergence-accommodation
conflict because the stimulus to accommodation is fixed by the display panel and viewing …

Compact varifocal lenses are essential to various imaging and vision technologies.
However, existing varifocal elements typically rely on mechanically actuated systems with …

Recent increased usage of stereo displays has been accompanied by public concern about
potential adverse effects associated with prolonged viewing of stereo imagery. There are …
