The present invention relates to an electronic device. More particularly, the present invention relates to an electronic device used in virtual reality (VR), augmented reality (AR), mixed reality (MR), etc.

Disclosed herein is an electronic device which includes: a frame including at least one opening and worn on a human body of a user; a control unit fixed to the frame and generating an image; and a display unit fixed to the opening of the frame and showing the image to the user, in which the frame includes a front frame including the at least one opening and first and second side frames which extend in a first direction crossing the front frame at both ends of the front frame and are parallel to each other, and at least one of a first length of each of the first and second side frames and a first interval between the first side frame and the second side frame is adjustable.

This application discloses virtual reality (VR) glasses, and a lens barrel adjustment method and apparatus, and relates to the field of VR technologies. The VR glasses includes a glasses body and two lens barrels that are symmetrically disposed within the glasses body. Each of the two lens barrels includes a lens barrel body and a lens barrel kit. The lens barrel kit is provided with a first adjustment component. The lens barrel body is provided with a second adjustment component. The lens barrel kit and the lens barrel body are configured to perform relative movement through coordination of the first adjustment component and the second adjustment component.

A wearable device may include a head-mounted display (HMD) for rendering a three-dimensional (3D) virtual object which appears to be located in an ambient environment of a user of the display. The relative positions of the HMD and one or more eyes of the user may not be in desired positions to receive, or register, image information outputted by the HMD. For example, the HMD-to-eye alignment vary for different users and may change over time (e.g., as a given user moves around or as the HMD slips or otherwise becomes displaced). The wearable device may determine a relative position or alignment between the HMD and the user's eyes by determining whether features of the eye are at certain vertical positions relative to the HMD. Based on the relative positions, the wearable device may determine if it is properly fitted to the user, and provides feedback on the quality of the fit to the user, and may take actions to reduce or minimize effects of any misalignment.

An adjustable frame assembly for augmented reality eyewear. The frame assembly includes a face portion for supporting at least one waveguide that creates an eye box, a support rest for supporting the face portion on a user, and a coupling for adjusting the position of the face portion relative to the support rest. This enables movement of the waveguide eye box relative to the support rest to position the eye box in front of the wearer's eyes.

Systems and methods to aid a welder or welding student. A system may provide a real-world arc welding system or a virtual reality arc welding system along with a computerized eyewear device having a head-up display (HUD). The computerized eyewear device may be worn by a user under a conventional welding helmet as eye glasses are worn and may wirelessly communicate with a welding power source of a real-world arc welding system or a programmable processor-based subsystem of a virtual reality arc welding system.

A display device 1A includes: a frame 10 that includes a front portion 11 disposed in front of an observer 50, temple portions 12 extending from both ends of the front portion, and a pad portion 17, and is to be mounted on the head of the observer 50; and an image display device attached to the frame 10. The image display device includes: an image forming device 30; and an optical device 40 on which light emitted from the image forming device 30 is incident and from which the light is emitted toward the observer. One end portion 40A of the optical device is fixed to a temple portion side of the front portion 11. The other end portion 40B of the optical device is disposed on a pad portion side of the front portion 11. A light shielding member 60 that prevents external light from being incident on the other end portion 40B of the optical device from above the other end portion 40B of the optical device is attached to the pad portion side of the front portion 11.

A system to support communication and control in a welding environment is disclosed. In one embodiment the system includes an internet-of-things (IoT) technology platform configured to provide scalable, interoperable, and secure communication connections between a plurality of disparate devices within a welding environment. The system also includes a welding power source configured to communicate with the IoT technology platform. The system further includes a computerized eyewear device. The computerized eyewear device includes a control and communication circuitry configured to communicate with the welding power source via the IoT technology platform. The computerized eyewear device also includes a transparent display configured to display information received from the welding power source via the IoT technology platform while allowing a user to view a surrounding portion of the welding environment through the transparent display.

A computing device includes an interface configured to interface and communicate with augmented reality glasses associated with a user, a memory that stores operational instructions, and processing circuitry operably coupled to the interface and to the memory that is configured to execute the operational instructions to perform various operations. The computing device receives the information that is related to the position and/or movement of the augmented reality glasses with respect to the user from monitoring component(s) of the augmented reality glasses. The computing device processes that information to determine the position and/or the movement of the augmented reality glasses with respect to the user. The computing device transmits media to the reality display of the augmented reality glasses to be consumed by the user and modify at least a portion of the media based on the position and/or movement of the augmented reality glasses with respect to the user.

A nose pad structure suited for a head-mounted device is provided. The nose pad structure includes a first nose pad and a second nose pad. The first nose pad has a first fixing portion assembled to the head-mounted device and a first free portion. The second nose pad has a second fixing portion assembled to the head-mounted device and a second free portion being movably overlapped with the first free portion. When a user wears the head-mounted device, the first and the second nose pads cover and contact the user's nose, and an overlapping status of the first and the second free portions is adjusted according to the user's nose shape.

A wearable display device includes a first display device and a second display device configured to display images correspondingly to left and right eyes, a first flexible board extending from the first display device to the second display device and configured to transmit a signal, and a second flexible board disposed overlapping the first flexible board. The first flexible board includes a surface overlapping the second flexible board and an opposite surface from the surface overlapping the second flexible board, the opposite surface being shielded, and the second flexible board includes a surface overlapping the first flexible board and an opposite surface from the surface overlapping the first flexible board, the opposite surface being shielded.
