I would have to say that it currently is both augmenting and competing
in the sense that the screen has to be viewed at least to see where one
is at and going . I am very interested in solutions to this that
minimize that periodic disconnect (like a pda or eventually smart
eyewear so you don't even have to look down at all.
The other side of it is that there is an opportunity for a lot of play and
metaphor in the interface. We use a map that is accurate but is acually
many decades old (the buildings haven't changed ) and are interested in
eventually using multiple layers that can, at times, slip. Different
senses of place and mapping, interface and data, references to time and
usage with different ways of presenting information that could at times
slip in and out at certain locations.
We actually start the program and talk to the people at first , then let
them go. It is much more their experience and their ultimate authoring in
a barthean sense of their path sets a sequence that they form (as we
designed it to function).
We watch them as they walk away and return and have learned a lot from
that. We take drivers licenses as a deposit.
