My colleague Chris Kueh reminds me regularly that wayfinding needs three things:
* The individual's perception of the world in the moment (what you can perceive
about the hospital)
* Idea of the world in the person's head (the kinds of ways the world fits
together including the layout of hospitals)
* Map representing some bits of the world near where you are (e.g. red lines
pointing to the vampire department - a map can also be a human telling us where
to go)
When the quality of one or more of these goes down, the others must be (or can
be) improved to make up.
Too often we have the tendency to focus on only one of them...
Cheers,
Terry
