Head-worn computers with eye-imaging systems include a camera system positioned in a head-worn computer, wherein the camera system is further positioned to capture eye-image light that originates as reflections from a user's eye, wherein the camera system is further positioned to capture eye-image light as a reflection from a partially reflective surface that is positioned in front of an image display in the head-worn computer, wherein image light, from the image display, is transmitted through the partially reflective surface. A processor is adapted to cause the camera system to capture the eye-image light. The processor is further adapted to cause a comparison of the captured eye-image light with a pre-stored eye image of a known user of the head-worn computer. In the event the comparison confirms the identity of the known user, the user is granted permission to view content to be presented in a display of the head-worn computer.

In some examples, a head-mounted device includes an image output device, and an optical element that is alternately moveable between a first position in which a first image output by the image output device is directed by the optical element towards a first location corresponding to a right eye position, and a second position in which a second image output by the image output device is directed by the optical element towards a second location corresponding to a left eye position.

A HMD includes a sensor for detecting an orientation of a main body, a display, and a field image display unit for displaying a first image in a predetermined first display region of the display and displaying a second image related to the first image in a second display region of the display on a screen of the display. The field image display unit determines the second display region on the screen of the display according to the orientation of the main body.

A system and method for rendering perspective adjusted views is provided. A registration code is generated for a mobile computing device and includes static and dynamic information about the mobile computing device. A representation of the registration code changes based on a change in the dynamic information of the mobile computing device. The registration code is provided to at least one other mobile computing device and registration of the other mobile computing device with the mobile computing device is performed upon receipt of the registration code by the other mobile computing device. A view of the mobile computing device and other mobile computing device is synchronized based on respective positions of the mobile computing device with respect to the other mobile computing device.

A head-mounted display device includes a see-though display providing both eyes of a user with a view of a physical object, a processor, and a non-volatile storage device holding instructions executable by the processor to: display an image that corresponds to the physical object to a first eye of the user at an offset to the physical object; display blocking light to a second eye of the user; in response to alignment user input, move a position of the image relative to the physical object; in response to completion user input, determine the inter-pupillary distance of the user; and calibrate the head-mounted display device based on the inter-pupillary distance.

A display device controlled via a smart phone (preferably using an TNC App) to display content selected by a requesting rider (e.g., code, symbol, the rider name, or a photo) in a clear and visible way to the waiting rider is a convenient method to identify the rider's designated vehicle instead of trying to search through model, color, and license plates of approaching vehicles as they enter a pickup area (e.g., airport designated area). The selected content is displayed on a display unit on the designated vehicle, and is transmitted to the display unit via a server associated with the designated vehicle using a secure protocol.

A processing system of a mobile device may determine the device's predicted viewport, which defines a portion of a real world environment that is expected to be visible to the device's user at a future time. The processing system may determine a set of extended reality anchors that are present in the real world environment, where each anchor stores a digital object that, when rendered by the device and presented to the user simultaneously with the real world environment, creates extended reality media. The processing system may remove a first subset anchors from the set, where locations of anchors in the first subset fall outside a threshold distance from the predicted viewport. The removing results in a second subset of anchors remaining in the set. The processing system may download a digital object from a second device, where the digital object is stored by an anchor of the second subset.

A system for updating continuous image alignment of separate cameras identifies a previous alignment matrix associated with a previous frame pair captured at one or more previous timepoints by a reference camera and a match camera. The previous alignment matrix is based on visual correspondences in the previous frame pair. The system also identifies a current matrix associated with a current frame pair captured at one or more current timepoints by the reference camera and the match camera. The current matrix is based on visual correspondences in the current frame pair. The system also identifies a difference value associated with the reference camera or the match camera relative to the one or more previous timepoints and the one or more current timepoints. The system also generates an updated alignment matrix by using the previous alignment matrix, the current matrix, and the difference value as inputs.

A head-up display for a vehicle includes: a display panel, a deflector having a plurality of microlenses, and an image generator. The image generator is configured to generate a plurality of primary elementary images which are multiplied by an optical multiplier into elementary images, which are in turn assigned in each case to a respective one of the plurality of microlenses.

A display control device for controlling a display position of a virtual image displayed and superimposed on a foreground in a vehicle (A), includes: an information acquisition unit for acquiring state information of the vehicle and extracting attitude change information and vibration information of the vehicle from the state information; a position correction unit for correcting a displacement of the display position of the virtual image with respect to the foreground caused by the attitude change of the vehicle, based on the attitude change information; a rough road determination unit for determining whether a road is a rough road, the road on which the vehicle is traveling or scheduled to travel, based on the vibration information; and a correction suppression unit for suppressing a correction control of the display position executed by the position correction unit and continuing to display the virtual image, based on a rough road determination.
