    Abstract: One embodiment provides a method comprising determining a spatial relationship between an augmented reality (AR) device and a camera-equipped device. The AR device is worn by a user. The camera-equipped device is positioned within proximity of the user. The method comprises determining, based on the spatial relationship, minimum and maximum boundaries of a user volume encompassing a head and one or more extremities of the user. The minimum and maximum boundaries represent a reduced depth range that is narrower than a full depth range of a camera frustum of the camera-equipped device. The method further comprises encoding, based on the minimum and maximum boundaries, a depth image frame captured via the camera-equipped device, and transmitting the encoded depth image frame over a remote network connection. A reconstructed 3D image based in part on the encoded depth image frame is rendered by a different AR device.

    Abstract: A method includes obtaining real-time video captured using one or more imaging sensors of an immersive headset. The method also includes processing the real-time video to identify one or more real-world objects and render the one or more real-world objects on at least one display of the immersive headset. The method further includes allowing a user of the immersive headset to select at least one of the one or more real-world objects or at least one spatial volume containing the at least one real-world object. The method still further includes displaying an extended reality view on the at least one display while overlaying, on the extended reality view, a representation of at least a portion of the at least one real-world object or the at least one spatial volume in one of multiple modes that each show the representation differently.
