Discussion
The process of developing the AR experiment was a creative one both in the
elaboration of the application concept and in the creation of the augmentations
(e.g. videos, 3D modeling or images), which were implemented by artists and
technicians.
The AR/MR technology allowed the mix of real and virtual worlds and brought
about an augmentation of both. The techniques were the combination, in the same
visualization, of the real environment and the virtual information, resulting in a new
reality, complemented by annotating the real world portion of it with visual and
textual information.
For the creative use of the AR technology potential, it is necessary to understand
the AR processes in order to select the most adequate one for the application
purpose. One of this is the tracking process. In our case, we decided to use location-
based tracking and 3D cloud point modeling of a real object. The 3D tracking is
an advanced method, which allows the AR applications to integrate naturally with
the real world and thus avoid using markers or reference images. Metaio's AR
technologies implement this 3D tracking of pre-modeled objects.
