An information processing device according to an embodiment of the present technology includes a user information acquisition unit, an object information acquisition unit, and an output control unit.The user information acquisition unit acquires information associated with a gaze position of a user while automatically playing back content from a sound source in a space where the user is present at a first control volume. The object information acquisition unit acquires position information associated with the sound source and position information associated with a first object of the user's gaze. When the user's gaze position moves from the first object toward the sound source, the output control unit performs a first output control so as to provide the user with the content at a second control volume different from the first control volume.
