I would be very grateful if you could help me with an
AR-related issue. I am a Master student of Multimedia
at the Vrije Universiteit Amsterdam (with Gerrit van
der Veer as principal professor) doing my thesis about
the creation of a portable multimedia device for
visitors of a recently excavated archaeological site.
I am conducting this project at the University of
Lleida, Catalunya, Spain.
This device will have to be context-aware in order to
show relevant information and a 'virtual panorama', te
latter meaning that when the visitor takes his device
and puts it before him and looks around, he will see
how the site appeared in the selected period from his
current point of view.
What tracking method is best to deduce the device's
position and orientation? I have been thinking about
using ARToolkit, because of the free availability of
the software, low costs and the ease of installing it.
But my main question is: will this work in an outdoor
area with a diameter of about 20 m? It consists of
remains which are at maximum half a meter high. How
far can the fiducials be at maximum? Are there
alternative systems available which use natural
features instead of fiducials?
What about differential GPS? Anyone using it now can
tell me about the needed equipment, weight and cost?
I would be highly thankful for any advice, helpful
information or relevant links.

site, 'Els Vilars'):
