Abstract: Aspects of the present disclosure relate to headset virtual presence techniques. For example, a participant of a communication session may not have an associated video feed, for example as a result of a user preference to disable video communication or a lack of appropriate hardware. Accordingly, a virtual presence may be generated for such a non-video participant, such that the non-video participant may be represented within the communication session similar to video participants. The virtual presence may be controllable using a headset device, for example such that movements identified by the headset device cause the virtual presence to move. In some instances, user input may be received to control emotions conveyed by the virtual presence, for example specifying an emotion type and/or intensity.
