  • Publication number: 20240386678
    Abstract: A method for realigning components of image-projection systems for a head-wearable devices is described herein. The method includes, while an image is being presented to the user's first eye using a first image-projection system of a head-wearable device and the image is being presented to a user's second eye using a second image-projection system of the head-wearable device, selecting one or both of (i) a selected point in time at which to present a realignment pattern via the head-wearable device and (ii) a selected location within the image at which the realignment pattern should be presented. The method further includes, presenting, via the head-wearable device, the realignment pattern at one or both of the selected point in time and the selected location. The method further includes, modifying presentation characteristics for the first image-projection system or the second image-projection system based on the presenting of the realignment pattern.

  • Publication number: 20240329396
    Abstract: A display waveguide is configured to direct a first portion of display light to an eye along a first optical path. A disparity waveguide is configured to direct a second portion of the display light to a disparity sense circuit along a second optical path separated from the first optical path.

  • Patent number: 12013531
    Abstract: A near-eye optical assembly includes a display waveguide and an optical structure. The display waveguide is configured to receive display light and to direct the display light to an eye of a user. The optical structure includes an input coupler, an optical path, and an output coupler. The input coupler is disposed to receive a portion of the display light that propagates through the waveguide. The optical path directs the portion of the display light from the input coupler to an output coupler that is configured to provide the received portion of the display light to a disparity sense circuit.

  • Patent number: 11562529
    Abstract: A method includes generating a depth map of a real environment as seen from a viewpoint that comprises pixels having corresponding depth values of one or more physical objects. Based on the depth map a two-dimensional occlusion surface is generated representing at least a visible portion of the one or more physical objects that are located within a predetermined depth range defined relative to the viewpoint. The two-dimensional occlusion surface is posed in a three-dimensional coordinate system such that the two-dimensional occlusion surface is located at a predetermined distance from the viewpoint. The visibility of a virtual object is determined relative to the one or more physical objects by comparing a model of the virtual object with the two-dimensional occlusion surface, and an output image is generated based on the visibility of the virtual object.
