TLDR
In this article, a head-mounted display apparatus includes an image display, a wearing device with which the image display device is worn on a head of an observer, and an attachment member attached to the wearing device.Abstract:
A head-mounted display apparatus includes an image display device, a wearing device with which the image display device is worn on a head of an observer, and an attachment member with which the image display device is attached to the wearing device. The attachment member is capable of adjusting a position of the image display device relative to the wearing device independently in a first direction and in a second direction, the first direction being defined by a virtual line connecting centers of eyes of the observer, the second direction being perpendicular to the first direction and extending vertically with respect to the observer.read more

Optical device, and virtual image display device
Hiroshi Mukawa,Katsuyuki Akutsu +1 more
TL;DR: In this article, a virtual image display device with an optical waveguide to guide, by internal total reflection, parallel pencil groups meeting a condition of internal total reflections was presented. But the authors did not specify the conditions of the external reflection.
Patent
Substrate-guided optical devices
TL;DR: In this article, an optical device, having a light-transmitting substrate (20) having at least two major surfaces parallel to each other and edges; a display light source; optical means for coupling light from the light source into the substrate by internal reflection, and at least one partially reflecting surface (22) located in the substrate which is non-parallel to the major surfaces of the substrate wherein the source emits light waves located in a given field-of-view, that the light waves are collimated, and wherein an angular resolution is defined for the optical device.
Patent
Head-mounted display
TL;DR: In this article, a head-mounted display includes an image presentation unit configured to present an image to the eye of a user, a control unit that plays content data and controls the image presentation, and a power supply management unit that cuts off the power supplied to the presentation unit in response to the detection unit detecting the segmentation point.
