Psychegeography

From what I could understand from the article, Psychegeography is a type of map that is based on the emotions and behaviors of the individuals. Or maybe it's like an interactive map? I am sort of able to understand what exactly Psychegeography is but I am having a difficult time understanding how exactly it is used. I see that it is a type of map, but thats about it! The Wikipedia article isn't very helpful.
