Abstract: A method includes, while displaying a computer-generated object at a first position within an environment, obtaining extremity tracking data from an extremity tracker. The first position is outside of a drop region that is viewable using the display. The method includes moving the computer-generated object from the first position to a second position within the environment based on the extremity tracking data. The method includes, in response to determining that the second position satisfies a proximity threshold with respect to the drop region, detecting an input that is associated with a spatial region of the environment. The method includes moving the computer-generated object from the second position to a third position that is within the drop region, based on determining that the spatial region satisfies a focus criterion associated with the drop region.

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.

In some embodiments, an object can be reconfigured from an indirect manipulation mode into a direct manipulation mode by moving the object to a respective position in the three-dimensional environment in response to a respective gesture.

Abstract: Technology is described for (3D) space carving of a user environment based on movement through the user environment of one or more users wearing a near-eye display (NED) system. One or more sensors of the NED system provide sensor data from which a distance and direction of movement can be determined.

The positioning application can then determine positions of the input device based on the motion data and the images correlated with a map of the environment, and track a motion of the input device in the environment based on the determined positions of the input device.
