Provided is a head-up display apparatus for a vehicle. The apparatus includes combiner assembly which includes a combiner exposed outside a dashboard or hidden inside the dashboard through a slot formed in the dashboard, a driver which provides a driving force to the combiner assembly, and a slot opening/closing device which opens or closes the slot by the driving force of the driver. The slot opening/closing device includes a door which opens or closes the slot, a lever-door link of which one end is connected to the door and which rotates about a first rotation axis, and a lever of which one end is connected to the lever-door link, which rotates about a second rotation axis, and to which the combiner assembly is slidably connected.

A system for characterizing a visor mounted to a helmet, the helmet having at least one projector for directing light to reflect off the visor to image to an eye position, is described. The system includes a mounting structure configured to mount an image detector to the helmet, the image detector arranged to detect an image at the eye position, and a controller. The controller is configured to provide a test pattern, receive a detected image from the image detector disposed at an eye position based on the test pattern, compare the detected image to the test pattern to determine a characterization error corresponding to a distortion of the detected image, determine a correction function to correct the distortion, and correct for the distortion based on the correction function.

A lens mechanism for a head-worn display device and a method of assembling the lens mechanism is disclosed. The lens mechanism includes a first housing disposed on a head-worn display device, wherein the first housing includes a first lens display, a first optic and a first optic holder configured to rigidly maintain the first lens display and the first optic, wherein the first optic holder includes an aperture configured to allow light waves to pass from the first lens display to the first optic. The lens mechanism includes a second optic holder that includes a second optic configured for vision correction, wherein the second optic is interchangeable and located over the first optic. The second optic holder is configured to removably dispose the second optic to the head-worn display device.

A head-mounted display includes a front having a display housing and a back having a rear housing. A first member extends between the front and the back and is adjustable via an actuation of a first rotatable actuator and a first cabling mechanism. A second member extends between the front and the back and is adjustable via an actuation of a second rotatable actuator and a second cabling mechanism. A third member extends between the front and the back and is adjustable via the actuation of the second rotatable actuator and a third cabling mechanism.

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.

A lens mechanism for a head-worn display device and a method of assembling the lens mechanism is disclosed. The lens mechanism includes a first housing disposed on a head-worn display device, wherein the first housing includes a first lens display, a first optic and a first optic holder configured to rigidly maintain the first lens display and the first optic, wherein the first optic holder includes an aperture configured to allow light waves to pass from the first lens display to the first optic. The lens mechanism includes a second optic holder that includes a second optic configured for vision correction, wherein the second optic is interchangeable and located over the first optic. The second optic holder is configured to removably dispose the second optic to the head-worn display device.

A head-mounted device may be provided with displays. The displays and lenses through which images on the displays are viewed may be mounted in optical modules. Positioners may be used to move the optical modules towards and away from each other to adjust the head-mounted device to accommodate different user interpupillary distances. To support and guide the optical modules, the optical modules may be slidably mounted to guide rails. The guide rails may be biased against the optical modules using biasing systems. By using the biasing systems, misalignment between the optical modules can be reduced. If desired, guide rail sensors may be used to monitor the positions of the guide rails. In some configurations, the optical modules may be mounted to the guide rails using kinematic mounting.

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.

A technique includes constructing a WCS (world coordinate system) as a three-dimensional, Cartesian coordinate system based at least in part on (i) a plurality of anchor points detected in a physical space around a device and (ii) a secondary source of information that assists in localizing objects in the physical space. The technique further includes providing the WCS to the device as a coordinate system in which to place holograms.
