Abstract: Aspects of the present disclosure are directed to controlling a sending side of an augmented call based on a receiving user's gaze. Some implementations provide a hologram moderation system in which a receiving user's gaze can control how the system generates a representation of a sending user on a sending side. For example, some implementations can moderate the capture or generation of hologram data representing the sending user when the receiving user isn't focused on the hologram that results from the data. Such moderations can reduce power consumption, bandwidth, heat production, and/or processing power needed by the artificial reality system when the receiving user is not looking at the hologram of the sending user, such as when the sending user is in the receiving user's periphery or outside the receiving user's field-of-view.
