Abstract: Examples are disclosed that relate to computing devices, head-mounted display devices and methods for remote collaborations. In one example a computing device receives receive a spatial mapping of a first three-dimensional environment and determines that a volumetric space in the spatial mapping satisfies at least one collaboration criterion. The collaboration criterion comprises a first object in the first three-dimensional environment and a second object in a second three-dimensional environment sharing a common semantic label. Based on determining that the volumetric space satisfies the collaboration criterion, a shared hologram is displayed by a first display device at the first object in the first environment and by a second display device at the second object in the second three-dimensional environment.

Abstract: Examples are disclosed that relate to computing devices, head-mounted display devices and methods for remote collaborations. In one example a computing device receives a first spatial mapping of a first environment and a second spatial mapping of a second environment. The computing device determines that a first volumetric space in the first environment and a second volumetric space in the second environment each satisfy at least one collaboration criterion. Based on this determination, an indication of the first volumetric space is displayed by a first display device in the first environment, and an indication of the second volumetric space is displayed by a second display device in the second environment.

Abstract: A method of and system for visualizing a sound source is disclosed. The method may include analyzing an audio signal received by a sound transducer to determine a positional direction of the sound source, determining whether the positional direction of the sound source falls outside a field of view of a user, and in response to determining that the positional direction of the sound source falls outside the field of view of the user, rendering on a display unit a visual representation of the sound source. The visual representation of the source is rendered on a virtual surface at a location within the field of view of the user, the location corresponding to at least one of a distance of the source from the user and a positional direction of the source with respect to the user.
