Absolutely any experience with VR or AR, whether for work or leisure, depends on a good interactive narrative. The virtual or mixed reality must (1) make sense to the user based on who they are (2) respond to the user in a way that makes sense, (3 guide him or her though some process, like adventuring, building, socializing, etc., and (4) leave the user with a valuable take-away.  This can be done with any interactive media, but VR and AR have particular advantages and limitations, makin them a genuinely new media. They are also different segments of the same continuum of immersive media; we will look at the big picture there. Attendees of the talk will come away with a basic framework for thinking about how to build VR and AR to engage, entertain, and get work done.
