Disclosed are various embodiments regarding a head-mounted device. According to an embodiment, a mount device comprises: a housing comprising a front surface, a rear surface that can be mounted on a head, and a side surface surrounding the front surface and the rear surface; a coupling portion can be disposed in housing, and can be configured to be coupled so as to slope an external electronic device at a designated angle with regard to the side surface; a prism comprising a first surface capable of facing, at the designated angle, at least a part of a display included in the external electronic device that can be coupled to the coupling portion, a second surface capable of changing (through total reflection) the direction of light that is incident from the display through the first surface, and a third surface capable of emitting the light, the direction of which has changed; a mirror arranged between at least a part of the side surface and the third surface; and a splitter arranged between the mirror and the third surface to be capable of transmitting at least a part of light emitted through the third surface and changing the direction of the light, which is transmitted and then reflected by the mirror, to a direction corresponding to the rear surface. Various other embodiments are possible.

A head-up display for a vehicle in which an assembly structure of a screen and a picture generation unit (PGU) is reinforced. The head-up display for a vehicle according to one embodiment includes a lower case embedded with a board assembly, and a screen connected to the lower case in a plurality of directions and snap-fit-coupled to the lower case by passing through the board assembly in at least one direction.

A head mounted display device and a head mounted display assembly are disclosed in some embodiments of the present disclosure. The head mounted display device comprises a display body and a sound transmission member. The display body is configured to display an image. The sound transmission member is connected to the display body, and is provided with a sound amplification cavity, a mounting groove communicated with the sound amplification cavity and a sound outlet hole. The mounting groove is configured to accommodate an earphone. The technical solution of the present disclosure can further reduce sound leakage and reduce noise interference to the surrounding environment.

Method for taking a test using a smartphone including placing the smartphone into connection with a device, placing the device on a head of a person with the smartphone in a position in which a display of the smartphone is visible to the person, coupling the smartphone to the device and displaying test questions on the display. Cheating is detected by, for example, monitoring presence of the device on the head of the person by periodically obtaining biometric data from the person and analyzing a change in the biometric data relative to previously obtained biometric data for the person, and when a change is present, stopping display of the test questions and generating and transmitting a communication to a test-providing institution derived from the change in biometric data.

An optical display, including a first waveguide having a first set of surfaces, an input grating, a fold grating, and an output grating; an image input image node assembly; and a prismatic relay optics is provided. The prismatic relay optics may be configured to be optomechanically connected to the waveguide and the input image node assembly. The optical display is may also be configured to operate alone or as integrated with a headpiece to be used as a HUD. The HUD may have a first and a second configuration wherein the waveguide is decoupled or coupled.

Aspects of the present invention relate to speaker assemblies for head worn computers, including speaker assemblies in a temple portion of a head-worn computer.

A system and method for detecting a condition of an augmented reality system and/or controlling an aspect of the augmented reality system.

A virtual or augmented reality headset is provided having a frame, a pair of virtual or augmented reality eyepieces, and an interpupillary distance adjustment mechanism. The frame includes opposing arm members and a bridge positioned intermediate the opposing arm members. The adjustment mechanism is coupled to the virtual or augmented reality eyepieces and operable to simultaneously move the eyepieces to adjust the interpupillary distance of the eyepieces.

In one example, an apparatus may include a frame that includes an optical component configured for use with a near-eye display that is part of a head-worn display system. The frame magnetically attaches to the head-worn display system, and when the frame is attached to the head-worn display system, the frame may align the optical component for use with the near-eye display. Various other methods, systems, and computer-readable media are also disclosed.

Aspects of the present invention relate to speaker assemblies for head worn computers, including speaker assemblies in a temple portion of a head-worn computer.
