Abstract: A coded tracking system includes an imaging device and a target object that includes a plurality of locators emitting light according to a first pattern. An image of the target object captured by the imaging device includes light received by the imaging device from a subset of the plurality of locators. A pattern controller is configured to determine a resolution value for an adjacent pair of light sources in the captured image. The resolution value is indicative of the pattern controller being able to resolve the adjacent pair of light sources as two separate sources. The pattern controller determines a second pattern for the locators based on the resolution value. The second pattern improves a likelihood that the pattern controller can resolve between individual light sources emitting light in the second pattern. The pattern controller instructs the target object for the locators to emit light according to the second pattern.

Abstract: A head-mounted display (HMD) divides an image into a high resolution (HR) inset portion at a first resolution, a peripheral portion, and a transitional portion. The peripheral portion is downsampled to a second resolution that is less than the first resolution. The transitional portion is blended such that there is a smooth change in resolution that corresponds to a change in resolution between a fovea region and a non-fovea region of a retina. An inset region is generated using the HR inset portion and the blended transitional portion, and a background region is generated using the downsampled peripheral portion. The inset region is provided to a HR inset display, and the background region is provided to a peripheral display. An optics block combines the displayed inset region with the displayed background region to generate composite content.
