An eyeball tracking method based on light field sensing is provided. Firstly, light intensity image data of plenoptic images of respective eyes and direction data of infrared light are captured by light field cameras in real time, depth information of the plenoptic images is obtained according to the light intensity image data and the direction data of the infrared light, models with curvature are formed according to the depth information, regions where the models are located are determined as eyeball image plane regions, and normal vectors of respective eyeball image plane regions and positions of the normal vectors relative to respective light field cameras are determined to determine fixation directions of both eyes to complete tracking

A diaphragm for performing image position correction of a virtual image projectable onto a windshield of a vehicle by a head-up display. A first positioning mark, a second positioning mark, and a calibration mark are attached to a disk of the diaphragm. The disk is transparent at least in the region of the first positioning mark, the second positioning mark, and the calibration mark, so that a first image including the first positioning mark and a first positioning pattern recorded directly through the disk and output on the vehicle side, a second image including the second positioning mark and a second positioning pattern output on the vehicle side, mirrored by a mirror of the diaphragm and recorded through the disk.

A system and method for detecting a condition of an augmented reality system and/or controlling an aspect of the augmented reality system.

A system and method. The system may include a head-up display (HUD). The HUD may include a positionable combiner optical element (COE) and a combiner alignment detector (CAD) configured to conform images displayed on the positionable COE with a view through the positionable COE. The CAD may include a mirror that moves with the positionable COE, an infrared (IR) emitter configured to emit IR pulses onto the mirror with a duty cycle of less than 1% such that an average time-based radiance of the IR pulses is compatible with a night vision imaging system (NVIS), and an IR detector configured to receive the IR pulses reflected off of the mirror.

A head-mounted display device including one or more position sensors and a processor. The processor may receive a rendered image of a current frame. The processor may receive position data from the one or more position sensors and determine an updated device pose based on the position data. The processor may apply a first spatial correction to color information in pixels of the rendered image at least in part by reprojecting the rendered image based on the updated device pose. The head-mounted display device may further include a display configured to apply a second spatial correction to the color information in the pixels of the rendered image at least in part by applying wobulation to the reprojected rendered image to thereby generate a sequence of wobulated pixel subframes for the current frame. The display may display the current frame by displaying the sequence of wobulated pixel subframes.

A method, medium and system for auto-aligning displays of a head/helmet mounted display. The method, medium and system may provide for an auto-alignment of components of a headband, headgear, or a helmet. The method, medium and system may provide for a first sensor mounted to the helmet of a user and configured to communicate and transfer align with a vehicle comprising an inertial navigation system (INS). The method, medium and system may provide for display comprising a second sensor configured to communicate with the first sensor and transfer align the second sensor with the first sensor based on the transfer alignment of the first sensor with the vehicle. The method, medium and system may provide for wherein the first sensor and the second sensor comprise an inertial measurement unit (IMU). Further, the method, medium and system may also provide for the aligning of two displays on the head/helmet relative to each other in real time.

A test fixture (10) for HUD windshields (12) wherein aspherical devices (26) compensate for complex curvatures and optical aberrations in a heads-up display surface (16) of the windshield. Tunable lenses cooperate with a movable test matrix to improve image resolution and enhance ghost image reduction.

The head-up display includes an imaging position changer configured to change a position of a virtual image between a far visual position far from an observer and a near visual position close to the observer. The imaging position changer inclines the virtual image at the far visual position by a second inclination angle with respect to a perpendicular plane to a reference light beam reaching a center of a viewpoint region in which a viewpoint of the observer is located, to move an upper end thereof in a forward direction of the moving object, and inclines the virtual image at the near visual position by a first inclination angle smaller than the second inclination angle with respect to the perpendicular plane to the reference light beam, to move the upper end in the forward direction of the moving object.
