Adjustable lens technology has the potential to improve Head Mounted Displays (HMDs)
through style and comfort by providing optical prescription correction and focussing …

We present a varifocal system for generating consistent accommodation cues and providing
prescription correction in Virtual Reality Head-Mounted Displays (VR HMDs). The proposed …

With recent developments in the manufacturing of freeform surfaces, Alvarez lenses have
recently surfaced as an attractive method to achieve large focal ranges rapidly while still …

The vergence-accommodation conflict is a fundamental cause of discomfort in today's Virtual
and Augmented Reality (VR/AR). We present a novel software platform and hardware for …

An accommodation-free displays, also known as Maxwellian displays, keep the displayed
image sharp regardless of the viewer's focal distance. However, they typically suffer from a …

Current head-mounted displays (HMDs) provide only a fixed lens focus. Viewers have to
decouple their accommodation and vergence responses when viewing stereoscopic images …

Alvarez lenses offer accurate and high-speed, dynamic tuning of optical power through a
lateral shifting of two lens elements, making them an appealing solution to eliminate the …

Since the recent slowdown in the smartphone market, studies for wearable devices are
briskly being carried out to find new markets, such as virtual reality devices. In this paper, a …

This chapter introduces design and principles of head mounted displays (HMDs), as well as
their state-of-the-art examples, for augmented reality (AR). Section 2 introduces a brief …

Developing head-mounted displays (HMDs) that offer uncompromised optical pathways to
both digital and physical worlds without encumbrance and discomfort confronts many grand …
