A helmet includes a protective shell, a monocular eyepiece and a mounting element. The monocular eyepiece displays an image signal to a wearer of the helmet. The eyepiece includes an electronic input configured to input the image signal and at least one mechanical connector. The mounting element is mechanically connected to the protective shell and to the monocular eyepiece, and is shaped to allow the monocular eyepiece to slide along the mounting element and to be secured in front of a wearer's right eye or left eye.

An apparatus including a light source, a first display, a first polarizing beam splitter having a first light input surface, a first light input transmission surface, a first display interface surface, and a first display projection surface, a second display, a second polarizing beam splitter having a second light input surface, a second display interface surface, and a second display projection surface, and a retarder that is positioned between the first light input transmission surface and the second light input surface is disclosed.

A head-mounted display device is provided, the head-mounted display device including: a display element; a light guide prism that includes an incident surface through which image light from the display element enters and that guides the image light to user's eyes; and a housing that contains the display element and the light guide prism; and support unit that fixes the housing to user's head. The light guide prism is partially covered by and contained in the housing. A portion of side surface of the light guide prism covered by the housing is formed with a first groove, and portion of side surface of the light guide prism exposed outside the housing is formed with a second groove. Depth of the first groove measured from the side surface is greater than that of the second groove.

Disclosed herein are systems, methods, and devices for implementing a mono-eye head-up display (HUD), being capable of producing content for only one eye of a viewer of a combiner of the HUD, the eye chosen being adjustable. The aspects disclosed herein accomplish this through disclosing structures and methods for implementing a backlighting portion of the HUD.

To provide a head-mounted display capable of finely adjusting a position of a display in a left-right direction. The present technology provides a head-mounted display including an optical plate that is arranged in front of an eyeball of a user and causes image display light to reach the eyeball. The optical plate is pivotable in a left-right direction about a center of the eyeball as a pivot center. The head-mounted display of the present technology may be a monocular type.

A head mount display includes a frame attached to a head of an observer, an image display unit that displays an image to be visually recognized by the observer, a fixing part that fixes the image display unit to the frame, an detection part that detects a signal according to a relative attitude of the image display unit with respect to the frame, and a control part that controls the image displayed by the image display unit based on the output signal of the detection part.

A head-mounted display device includes: an image-light generating unit for right eye that generates image light from image data for right eye and emits the image light; an image-light generating unit for left eye that generates image light from image data for left eye and the image light; a light guide units that guide the emitted image lights to the left and right eyes of the user; and a display control unit that transmits control signals for controlling the emission of the image lights respectively to the image-light generating unit for right eye and the image-light generating unit for left eye. The display control unit transitions, according to a condition set in advance, the head-mounted display device to a power saving state for causing one of the image-light generating unit for right eye and the image-light generating unit for left eye to stop the emission of the image light.

Various devices, arrangements and methods for managing communications using a head mounted display device are described. In one aspect, tracking data is generated at least in part by one or more sensors in a head mounted display (HMD) device. The tracking data indicates one or more facial movements of a user wearing the HMD device. A patch image is obtained based on the tracking data. The patch image is merged with a facial image. Various embodiments relate to the HMD device and other methods for generating and using the patch and facial images.
