A head-mounted display includes a varifocal actuation block and an optics block coupled to the varifocal actuation block. An anti-creep system located in the varifocal actuation block includes a plurality of anti-creep mechanisms that are configured to prevent bearing ball creep associated with bearing balls in the varifocal actuation block. The bearing balls are used to move a movable carriage that is coupled to a fixed carriage in the head-mounted display via the anti-creep mechanism. The anti-creep mechanisms prevent bearing ball creep associated with the bearing balls from occurring in the varifocal actuation block by limiting the movement in an angular direction of the bearing balls that are used to move the movable carriage in a first direction in the head-mounted display.

In a vehicle display device, a locking mechanism has a first support part that supports a first end of a display panel and a second support part located at a position relatively different from the first support part. The second support part has a pair of urging portions that urge the display panel in a support state, and a first receiving portion that receives a lower surface of a second end of the display panel. Each of the urging portions is formed curving in an S shape when viewed from the optical axis direction, and a distal end portion formed at an end opposite to the fixed end portion has a second receiving portion that protrudes from an abutting surface toward the display panel and interposes the second end of the display panel between the second receiving portion and the first receiving portion, in the support state.

Aspects of the present disclosure relate to modular expansion systems for use in head-worn computing systems. In an head-worn computer, an electrical connector is adapted to electrically connect with a modular expansion module, wherein the modular expansion module adds a capability to the head-worn computer and is removeably mounted to the head-worn computer, and a mount is adapted to physically secure the modular expansion module to the head-worn computer

An image generation unit includes a display panel, a first illumination system, and a second illumination system. The display panel has a first and a second imaging regions adjacently arranged and located on the same plane. The first illumination system provides a first light beam incident on the first imaging region at a first incident angle. The first imaging region converts the first light beam into a first image beam. The second illumination system provides a second light beam incident on the second imaging region at a second incident angle. The second imaging region converts the second light beam into a second image beam. The optical paths of the first light beam and the second light beam do not intersect with each other. The first image beam and the second image beam leave the display panel at different light exit angles.

A head-mounted display includes a display host, a head belt base, a first lateral head belt, a second lateral head belt, an auxiliary head belt, a knob, a first driving component and a second driving component. The head belt base is connected to the display host through the first and second lateral head belts and the auxiliary head belt. The knob is pivoted to the head belt base, and the knob is coupled to the first and second lateral head belts through the first driving component and is coupled to the auxiliary head belt through the second driving component. The knob synchronously drives the first and second driving components, to drive the first and second lateral head belts through the first driving component and drive the auxiliary head belt through the second driving component. Alternatively, the knob drives one of the first driving component and the second driving component.

A display device includes: a first closed-bottom lens tube including a first display part on the closed bottom for displaying a first image; a second closed-bottom lens tube including a second display part on the closed bottom for displaying a second image; an adjustment mechanism including a first rod that extends from the first lens tube and a second rod that extends from the second lens tube and is rotatably connected to the first rod; and an image outputter that outputs the first and second images to the first and second display parts, respectively. The image outputter, in accordance with the angle of rotation of the first and second rods of the adjustment mechanism, controls and outputs the first and second images to bring the horizontal directions thereof closer to the arrangement direction of the first and second lens tubes.

A packing structure including a first packing component, a second packing component, and two lenses is provided. The second packing component is adapted to be combined with the first packing component detachably, such that a containing space is formed between the first packing component and the second packing component. The containing space is adapted to contain an electronic device. The two lenses are disposed on the second packing component. An image displayed by a display surface of the electronic device is adapted to be transmitted to outside of the containing space through the two lenses, so as to form a virtual reality image.

A wearable electronic device is disclosed herein. The device includes a housing, a light output module disposed in the housing and configured to output an image, a speaker module disposed in the housing, the speaker module including a conductive plate and a coil surrounding the plate, a battery disposed in the housing, and a power transmission structure disposed in the housing, and configured to transmit power from the battery to the light output module, wherein at least a portion of the power transmission structure is disposed above the plate.

In on the general aspect, a camera rig can include a first tier of images sensors including a first plurality of image sensors where the first plurality of image sensors are arranged in a circular shape and oriented such that a field of view of each of the first plurality of image sensors has an axis perpendicular to a tangent of the circular shape. The camera rig can include a second tier of image sensors including a second plurality of image sensors where the second plurality of image sensors are oriented such that a field of view of each of the second plurality of image sensors has an axis non-parallel to the field of view of each of the first plurality of image sensors.

A system for augmented reality comprises a helmet and a container body within which a video unit is housed that comprises a device for acquiring images of a real scene and a display device for displaying at least the aforementioned images. A support body is, furthermore, provided configured to engage the container body to the helmet. The container body and the support body are provided with respective first and second engagement members configured to selectively and alternatively removably engage the container body to the support body in a first engagement position, in which the device for acquiring images is arranged to acquire images with a first predetermined field of view and the display device is positioned within the field of view of the user, and at least a second engagement position, in which the device for acquiring images is arranged to acquire images with a second predetermined field of view.
