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.

Abstract: A panoramic image system with parallax mitigation includes image sensors, a head tracker, a display, and a processor. Each image sensor is fixedly mounted a predetermined linear distance from a first reference axis and is disposed adjacent to at least one other image sensor and to point in a direction that is offset from its adjacent image sensor by a predetermined angle. The head tracker is configured to sense at least the angular position and movement direction of a viewer's head about a second reference axis and to supply an azimuth position signal representative thereof. The display is configured to selectively display images sensed by each of the image sensors. The processor is in operable communication with the image sensors, head tracker, and display. The processor is configured, based at least on the azimuth position signal, to command the display to display images sensed by only one image sensor.

Abstract: A method for displaying images on a head-mounted display (HMD) device that compensates for a user's vestibulo-ocular reflex (VOR) response. The displayed HMD image is compensated for predicted eye position such that the displayed image stays centered on the fovea of the eye, during transient eye movement caused by head motion, resulting in better display readability, discernment and cognitive processing.

Abstract: An augmented reality system is provided and a method for controlling an augmented reality system are provided. The augmented reality system, for example, may include, but is not limited to a display, a memory, and at least one processor communicatively coupled to the display and memory, the at least one processor configured to generate image data having a first resolution at a first rate, store the generated image data in the memory, and transfer a portion of the generated image data having a second resolution to the display from the memory at a second rate, wherein the second rate is faster than the first rate and the second resolution is smaller than the first resolution. This dual rate system then enables a head-tracked augmented reality system to be updated at the high rate, reducing latency based artifacts.

Abstract: 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.

Abstract: A system for tracking motion of an object comprises at least a first magnetic source configured to generate a static magnetic field, with the magnetic source fixed in a first coordinate frame, and a plurality of magnetic sensors configured to be located on the object and to detect the static magnetic field. The magnetic sensors are located in a second coordinate frame that is movable relative to the first coordinate frame. A processor is operative to receive magnetic field data from the magnetic sensors. A memory unit coupled to the processor stores a magnetic field model or a magnetic field database defined for the first coordinate frame, and a magnetic sensor measurement model with uncertainties defined for the second coordinate frame. The processor computes and outputs an estimated position and orientation of the object based on the magnetic field data and other information stored in the memory unit.

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.

Abstract: A vision system is provided for confirming continuously updated approach information from a global positioning system or an instrument landing system with that from an inertial navigation system. The approach information from the inertial navigation system is displayed when the global positioning system or the instrument landing system is unavailable or whose approach information is determined to be invalid.
