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.

Abstract: Methods, systems, and devices for head wearable display devices are described. A device may capture a set of images over a set of orientations using a set of cameras positioned on an outward facing surface of the device. The set of images include a first subset of images captured by a first camera and a second subset of images captured by a second camera. The device may detect a set of facial features in each of the first subset of images and the second subset of images, and measure a set of inter-pupillary distances over the set of orientations based on the set of facial features in each of the first and second subset of images. The device may determine an inter-pupillary distance parameter based on aggregating the set of inter-pupillary distances over the set of orientations. The device may calibrate based on the inter-pupillary distance parameter.

Abstract: Systems, methods, and non-transitory media are provided for generating private 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; detecting a private region in the physical environment and a location of the private region relative to the pose of the XR device, the private region including an area estimated to be within a field of view (FOV) of a user of the XR device and out of a FOV of a person in the physical environment, a recording device in the physical environment, and/or an object in the physical environment; based on the pose of the XR device and the location of the private region, mapping a virtual private control interface to the private region; and rendering the virtual private control interface within the private region.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for operating a wearable display device. Certain aspects of the present disclosure provide a method for operating a wearable display device. The method includes determining a position of the wearable display device based on a motion sensor. The method includes rendering, by a graphics processing unit, an image based on the determined position. The method includes determining a first updated position of the wearable display device based on the motion sensor. The method includes warping, by a warp engine, a first portion of the rendered image based on the first updated position. The method includes displaying the warped first portion of the rendered image on a display of the wearable display device.

Abstract: A method for performing a remote procedure call between an application processor and a digital signal processor within a computing device. The computing device may compile interface description language data to generate stub software that executes on the application processor and skel software that executes on the digital signal processor. When an application executing on the application processor invokes a remote procedure call, the application processor may pack argument data within stack memory and transmit an interrupt to the digital signal processor, which may map the physical memory addresses of the argument data into local address space such that no copies of the argument data is made. The digital signal processor may execute skel software that unpacks the argument data and executes a service related to the remote procedure call.
