Tracking-based branching of media content

An apparatus comprising:

• at least one output device for rendering media content including a plurality of virtual objects and a plurality of triggers, each of said plurality of triggers being associated with at least one virtual object of the plurality of virtual objects;
• a tracking device for tracking a plurality of users of the apparatus;
• and
• a controller configured to:
• continuously receive, from the tracking device, tracking data of the plurality of users;
• match the tracking data to the plurality of triggers;
• if the tracking data matches at least one trigger, branch the media content into a plurality of branches including a main branch and at least one auxiliary branch, each auxiliary branch associated with at least one user;
• for each matched trigger, automatically adjust the at least one virtual object associated with the matched trigger in the associated auxiliary branch;
• simultaneously present the plurality of branches of the media content to respective users of the plurality of users;
• and
• join the at least one auxiliary branch with the main branch.
