    Abstract: A method for configuring a digital light projector (DLP) of an augmented reality (AR) display device is described. A light source component of the DLP projector is configured to generate a single red-green-blue color sequence repetition per image frame. The AR display device identifies a color sequence of the light source component of the DLP projector and tracks a motion of the AR display device. The AR display device adjusts an operation of the DLP projector based on the single red-green-blue color sequence repetition, the color sequence of the light source component of the DLP projector, and the motion of the AR display device.

    Abstract: Disclosed are systems and methods for adaptively adjusting brightness of a wearable device projection system. The systems and methods perform operations comprising: causing projection elements of the AR wearable device to project an image; receiving a measure of ambient light from an ambient light sensor; adjusting one or more hardware parameters of the projection elements of the AR wearable device based on the measure of ambient light; modifying one or more color values of the image displayed by the projection elements of the AR wearable device based on the measure of ambient light; and projecting the image with the modified color values using the projection elements of the AR wearable device with the adjusted one or more hardware parameters.

    Abstract: A method performed on an augmented reality (AR) wearable device includes providing an over-the-air (OTA) update to all processors of a three-processor system, each processor of the three processor system having a respective current plurality of partitions and a respective last plurality of partitions. A communication error is detected between two or more processors of the three processor system after the OTA update. Respective active partitions are set for at least one of three processors to the last respective partition. The three processors are rebooted.

    Abstract: A content creation system for extended Reality (XR) systems. The content creation system receives motion data of an XR device and generates trajectory data of a trajectory within a 3D environment model of a real-world scene based on the motion data where the trajectory simulates the motion of the XR device within the real-world scene. The content creation system receives user interaction event data and generates simulated sensor data based on the trajectory data, the 3D environment model, and the user interaction event data. The content creation system generates simulated tracking data based on the simulated sensor data and determines simulated power consumption data and thermal condition data based on operation of the computer vision component while generating the simulated tracking data. The content creation system generates a display from a user's perspective of the 3D environment model along with the simulated power consumption and thermal data.

    Abstract: Camera pipeline exposure timestamp error determination methods and systems that detect latency in rolling shutter camera systems. The exposure timestamp error determination system includes a rolling shutter image sensor configured to capture an image and a processor. The processor determines timestamp error by capturing the image using the rolling shutter image sensor where the image includes a bar code encoded with a barcode timestamp. The processor then obtains a system exposure timestamp corresponding to capture of the image by the rolling shutter image sensor and the barcode timestamp by decoding the bar code. Pipeline exposure timestamp error is then determined for the rolling shutter camera system by comparing the obtained barcode timestamp to the system exposure timestamp.
