VR does not need to know your coordinates as in visiting historic sites, that is more the task of AR (augmented reality). AR offers interactivity in a real world scenario as information can be superimposed on what you see in the real world. Imagine AR interactive quizzes in museums or while walking around historic sites. AR lends itself well to education and gamification. In the case of smart cities students can use AR to explore pollution/environmental issues in cities by superimposing live information dependent on the location and aspect of students. Where does your water come from? "Where can I see recycling points in my city?"
