Abstract: Examples are described of marking specified regions of stored image frame buffer data in an image frame buffer. An imaging system can read the specified regions of the image frame buffer to identify whether the marking has been overwritten or not. The imaging system can thus efficiently identify how much of the image frame buffer has been overwritten with data from a new image frame. Based on this, the imaging system can retrieve partial image frame data from the image frame buffer and can process the partial image frame data, for instance to composite the partial image frame data with virtual content and/or to perform distortion compensation. The processed partial image frame data can be uploaded to a display buffer and displayed by a display, either as-is or once more of the frame is captured and processed. The imaging system can also perform auto-exposure using the partial image frame data.

Abstract: Systems, methods, and non-transitory media are provided for generating obfuscated control interfaces for extended reality (XR) experiences. An example method can include determining a pose of an XR device within a mapped scene of a physical environment associated with the XR device; rendering a virtual control interface within the mapped scene according to a configuration including a first size, a first position relative to the pose of the XR device, a first ordering of input elements, and/or a first number of input elements; and adjusting the configuration of the virtual control interface based on a privacy characteristic of data associated with the virtual control interface and/or characteristics of the physical environment associated with the XR device, the adjusted configuration including a second size, a second ordering of input elements, a second number of input elements, and/or a second position relative to the pose of the XR device and/or first position.
