Semiotics seems to contain some useful concepts for looking at how humans perceptually might be able to begin talking about and understanding the effects of augmented reality, or of “mixed realms” as I’m calling them: real spaces with virtual elements, or any other combination of virtual and computer-generated virtual stimulus. But now I’m getting ahead of myself:

In semiotics, denotation is the surface or literal meaning encoded to a signifier, and the definition most likely to appear in a dictionary.

From a more internet-tech perspective, we could look at the signifier as being like the URI (universal resource identifier) anchor.
