Systems and methods are described for sharing a user interface between users. The system transmits live video simultaneously to a plurality of users. Then, the system determines a subset of the plurality of users, such that the subset includes two users that have a predetermined relationship. Then, during playback of the video, the system detects an object in a frame of the video corresponding to preferences of the first user. In response, the system determines whether the second user is researching information related to the object during playback of the video. If the second user is researching such information, the system streams a mirror image of a user interface with which the second user is performing the researching to the first user.
