Provided is a display apparatus including an image forming device configured to form an image, an optical system configured to provide an output image by combining light containing an outside landscape with the image formed by the image forming device, and a driving device configured to adjust a distance between the image forming device and the optical system, wherein the driving device includes a fixed frame, a movable frame which faces the fixed frame and is movable, an actuator configured to change a distance between the fixed frame and the movable frame, and a fixing member configured to fix the distance between the fixed frame and the movable frame, wherein the image forming device is fixed to the movable frame.

A system, method, and computer-readable medium are disclosed for performing adjustments on a virtual reality (VR) headset. A user preference is determined as to a clamping force and an interpupillary distance (IPD) as applied to the VR headset. The user preferences are stored in a unique user profile. Adjustments are performed on the VR headset as to clamping force and IPD.

A head-mounted augmented reality device (10) includes a pair of optical modules (12) for the right and left eyes of the user, each having a collimating display source (14) optically coupled to a light guide (16) for directing image illumination towards an eye of the user. A support structure (20) is supported by the head of the user. An optical bench (22) provides a first set of alignment features (26, 28, 32, 74) for aligning and affixing the right optical module and a second set of alignment features (26, 28, 32, 74) for aligning and affixing the left optical module. A suspension arrangement suspends the optical bench relative to the support structure. The optical bench (22) provides the sole mechanical connection between the pair of optical modules (12) and the support structure (20).

A display apparatus includes: a first lens barrel in a bottomed barrel shape and including, at the bottom, a first display that displays an image; a second lens barrel in a bottomed barrel shape and including, at the bottom, a second display that displays another image; a support member elongated in an arrangement direction of the first and second lens barrels, and supporting, by passing through the first and second lens barrels in the arrangement direction, at least one of the first and second lens barrels to allow the at least one lens barrel to move in the arrangement direction; and temple parts respectively connected to two ends of the support member in the arrangement direction. The first lens barrel includes first and second sound pickup devices, the second lens barrel includes third and fourth sound pickup devices, and the temple parts respectively include fifth and sixth sound pickup devices.

Apparatuses, methods, systems, and program products are disclosed for adjustable bone conduction speaker for head mounted display. An apparatus includes a sliding member couplable to a head mounted display (“HMD”) unit and comprising at least one bone conduction speaker, the sliding member adjustable along a first axis to position the bone conduction speaker along the first axis. An apparatus includes a protrusion member coupled to the sliding member and housing the at least one bone conduction speaker, the protrusion member adjustable along a second axis, substantially perpendicular to the first axis, to position the bone conduction speaker along the second axis.

A head-mounted device may have a head-mounted housing and optical components supported by the head-mounted housing. The optical components may include cameras, movable optical modules, and other components. Each optical module may include a display that displays an image and a lens that provides the image to a corresponding eye box. Optical self-mixing sensors may be included in the optical modules and other portions of the head-mounted device to measure changes in optical component position. In response to detecting a change in optical component position, actuators in the device may be adjusted to move the optical components or other action may be taken to compensate for the change.

A head-mounted display includes a display unit, a head support, a power storage device, and one or more receiving coils. The head support is coupled to the display unit and configured to engage a head of a user for supporting the display unit thereon. The power storage device is coupled to the display unit for storing power to be supplied to the display unit. The one or more receiving coils are coupled to the head support for inductively charging the power storage device.

A head-up display device includes a light source component, an image generating element and at least one sensor. The light source component includes at least one light source configured to emit light. The image generating element is configured to convert light emitted by the at least one light source into image light and output the same. The at least one sensor is located at a side of the image generating element close to the light source component. The sensor of the head-up display device has the potential to affect the image light. Also provided are a head-up display system including the head-up display device, and a transport device including the head-up display device or the head-up display system.
