  • Eyewear with integrated peripheral display
    Patent number: 11624925
    Abstract: Systems and methods for projecting each of a chronology of images as a sequence of images using a shifting element as part of a near-eye display system are provided for use in virtual reality, augmented reality, or mixed reality systems. In some example embodiments, a chronology of images is received by a peripheral sequencing system. The system divides each image into image portions and generates sequences of image portions to recreate the images based on arrangement data. The system then causes a high-speed display of each sequence of images such that they appear simultaneous to a viewer. In some embodiments, the projection is transmitted to a shifting optical element such as a rotating micromirror that propagates a display to a user. In some embodiments, the system further detects and corrects for image and environmental distortions.
