3 The Strengths of Our System
3.1 Generic System
Our system is as generic as possible. It relies upon a dynamic calibration process
with a localization module. Our system is easy to move from one site to another,
and it is so designed that it can at the same time be regarded as belonging to the
category of
fixed devices
for augmented reality applications for heritage valori-
sation purposes, but with the added value that its included dynamic functionali-
ties make it perfectly suitable to be
mobile or duplicated all over the world
, as
well as to other purposes in dedicated augmented reality contexts (touristic, etc.).
As a result, the telescope can be set up on every site around the world:
l'Arc de
Triomphe (Paris, France)
,
Liberty Island (New
-
York, USA)
,
El Corcovado (Rio de
Janeiro, Brazil)
… to move it around, we simply need to integrate the required aug-
mented reality information and to specify the calibration coordinates.
3.2 Open Software System
Our system includes a modular software architecture which not only allows for
further developments on the applications tested on it, but also a seamless adapta-
bility to numerous fields of application besides heritage valorisation. Furthermore,
considering the large number of existing and potential industrial software model-
lers, we chose to design the core of our software architecture for the highest porta-
bility and with a view to a straightforward interfacing to all kinds of 3D modellers:

Stereoscopic-Monoscopic Vision
We chose to avoid stereoscopic vision, on the simple reasoning that our device is
meant to appeal to the widest audience, especially children. Stereoscopic vision is
