Weight Reduction is a Key Enabler for Augmented and Mixed Reality Advances

Abstract

Ultra‐flat, low‐density, high‐refractive‐index glass wafers enable waveguide weight to be cut in half and drive the long‐awaited breakthrough of augmented reality.

Liquid Crystal Technologies for Augmented and Mixed Reality Displays

“…Non‐waveguide‐based AR displays encompass a variety of technologies, including bird‐bath optics, holographic displays, retinal projection, and pin mirror optical combiners 11 . Waveguide‐based AR displays employ either refractive waveguides, which use cascaded mirrors, 12 or diffractive waveguides, which use various diffraction gratings such as surface relief gratings (SRG), volume Bragg gratings (VBG), and PVG.…”

Augmented-Reality Presentation of Household Sounds for Deaf and Hard-of-Hearing People

“…However, it is also considered that the amount of information that can be presented is limited to the modal vibration alone, but such a system can be helpful for someone who is also visually impaired. Moreover, AR devices are becoming gradually lighter [69] and are expected to become increasingly convenient in the future. Furthermore, previous studies have pointed out that in sound visualization systems for DHH people, the type and arrangement of the display are very important [42], suggesting that it is important to place the information in an easily viewed position.…”
