An augmented display system with dynamic see-through transmittance control is disclosed. The augmented display system includes: an augmented display screen; a tandem electrochromic (EC) filter disposed over the augmented display screen. The tandem EC filter includes a first window having a dominant first transmittance characteristic and a second window having a dominant second transmittance characteristic; and an augmented display transmittance controller configured to individually control the activation of the first window and the second window of the tandem EC filter, wherein the augmented display transmittance controller is configured to: determine from an ambient light sensor output the transmittance required from the first window and the second window for a selected augmented display luminance; and apply appropriate drive voltage waveforms to the first window and the second window to achieve the determined transmittance.

An optical tracker system is provided for tracking a location and orientation of a first object. The system includes a prediction module configured to determine a predicted location and orientation of the first object as a spatial prediction; a display module configured to generate display commands for a fiducial symbol based on the spatial prediction; a display unit configured to display the fiducial symbol based on the display commands; a camera unit configured to capture an image of the fiducial symbol displayed on the display device as a captured appearance; and a position determination module coupled to the camera unit and configured to receive the image from camera unit. The position determination module is configured to identify the fiducial symbol and determine the location and the orientation of the first object based on the captured appearance of the fiducial symbol.

NTE display systems and methods with optical trackers

A virtual window display includes: a plurality of collimated projector modules having contiguous exit pupils. Each collimated projector module includes: a display device configured to display a spatially modulated image along a flat or curved geometric image surface, and one or more optical lenses sharing a common curvature symmetry axis and configured to optically collimate light from the display device in the collimated projector module. The curvature symmetry axes of the plurality of collimated projector modules point in a plurality of angular directions and are substantially convergent along at least one axis at a finite distance from the plurality of collimated projectors. The total display FOV of the virtual window display is larger than the module FOV of each of the plurality of collimated projector modules.

A head-up display system and method are provided that suppress double images from a combiner by eliminating or reducing a reflection of a refracted image from the back surface of the combiner. The combiner contains a tilted axis polarizing structure that attenuates transmittance and subsequent reflection of a refracted polarized projector image but maintains high transmittance for the forward external scene imagery.

Apparatus and method for supressing double images on a combiner head-up display

A system and method of displaying a conformal-capable head-up display image is provided. Distortions caused by combiner curvature, for example, are removed by pre-distorting and projecting separate images for each eye. Shutter-based eyewear controls the visibility as the imagery is cycled, e.g., shuttered, between left and right eyes. The combined image generator, projector and eyewear system maintains minimal vergence errors, minimal dipvergence errors, acceptable average transmittance, and optionally, high conformality.

High transmittance eyewear for head-up displays

Provided is a compact display system and method for creating, with minimal volume, a focused, high quality, full color, large FOV virtual image characterized by eye-limited spatial resolution. The provided compact display (i) enables a flexible range of eye relief, and (ii) enables a large exit pupil.

System and method for a compact display

Information is presented on a touchscreen display. An available viewing surface area of the touchscreen is separated into a first zone and at least a second zone. The first zone is operable for presenting a critical portion of the information. The second zone is operable for receiving haptic user inputs. Usage of the first zone and the second zone are coordinated. The presentation of the critical information in the first separated zone, and/or a prompt related to at least one of the one or more haptic user inputs may be controlled based on the coordinated usage.

Interactive display

A hybrid projection display system that provides image quality superior to that of a traditional projection display system is provided. The provided hybrid projection display system flexibly supports arbitrary screen sizes and non-planar screen surfaces.

Methods and systems for operating a vehicular near-to-eye (NTE) display screen operable within an operational range limit are provided. An image is rendering on the NTE display screen within a predefined visibility range. The predefined visibility range is within the operational range limit. A luminance of at least a portion of the image is reduced in response to the NTE display screen being moved outside of the predefined visibility range and within the operational range limit.

A method for detecting and correcting drift associated with operation of a hybrid tracking system is provided. The method obtains a data signal from a first tracker subsystem having a first tracker latency time; for a defined window of time, the method captures snapshot input data for a second tracker subsystem having a second tracker latency time which is longer than the first tracker latency time; and captures synchronized data from the data signal which corresponds to the defined window of time; wherein the defined window of time comprises a time duration shorter than the second tracker latency time, to capture the snapshot input data. The method further determines a level of drift associated with operation of the first tracker subsystem; and adjusts operation of the first tracker subsystem according to the determined level of drift.

A system and method for optimizing image uniformity in a head-up display (HUD) are provided. An imaging subsystem is characterized in that if light of a first uniformity is propagated therethrough, an uncompensated image would be displayed to a user via uncompensated image light. The uncompensated image light has first and second portions with respective first and second values of a radiant property. A difference between the first and second values is a first amount. The light source is configured to emit source light of a second, predetermined uniformity through the imaging system such that a compensated image is displayed to the user via compensated image light. The first portion of the compensated image light has a third value of the radiant property, and the second portion of the compensated image light has a fourth value of the radiant property. A difference between the third and fourth values is less than the first amount.

A system and method are provided for leveraging emitted polarized electromagnetic radiation as a means to track relative orientation and position of an object with regard to another object. Six basic degrees of freedom including three angular and three translational are determined based on making multiple polarization-based measurements and then determining the corresponding geometry that would yield those measurements.

Polarized tracker system and method for tracking movement

A polarization plate is provided for use between a light source and a display panel, where the light source is configured to emit light having a plurality of planes of polarization and the display panel is configured to have a predetermined polarization axis. The plate includes a repolarization region and a prepolarization region. The repolarization region is configured to diffuse and to depolarize or rotate at least one plane of polarization of the light passing therethrough. The prepolarization region is disposed adjacent to and in contact with the repolarization region. The prepolarization region is configured to be substantially nonabsorbent, to allow passage of light having a plane of polarization that is substantially aligned with the predetermined polarization axis, and to prevent passage of light having a plane of polarization that is not substantially aligned with the predetermined polarization axis. In another embodiment, an interface is provided between the regions.
