Abstract: In one implementation, a method includes: obtaining a first depth estimation characterizing a distance between the device and a surface in a real-world environment, wherein the first depth estimation is derived from image data including a representation of the surface; receiving, using the audio transceiver, an acoustic reflection of an acoustic wave, wherein the acoustic wave is transmitted in a known direction relative to the device; and determining a second depth estimation based on the acoustic reflection, wherein the second depth estimation characterizes the distance between the device and the surface in the real-world environment; and determining a confirmed depth estimation characterizing the distance between the device and the surface based on resolving any mismatch between the first depth estimation and the second depth estimation.

Abstract: An electronic device such as a head-mounted device may present extended reality content such as a representation of a three-dimensional environment. The representation of the three-dimensional environment may be changed between different viewing modes having different immersion levels in response to user input. The three-dimensional environment may represent a multiuser communication session. A multiuser communication session may be saved and subsequently viewed as a replay. There may be an interactive virtual object within the replay of the multiuser communication session. The pose of the interactive virtual object may be manipulated by a user while the replay is paused. Some multiuser communication sessions may be hierarchical multiuser communication sessions with a presenter and audience members. The presenter and audience members may receive generalized feedback based on the audience members during the presentation.
