these objects could be drawn on a real image, producing an effect of immersion into
the newly created real-virtual environment.

Materiality: Textures and Colour
A final level of the fractal approach is represented by the visualization of the
attributes of the objects created through the recovered technologies. Besides the
shape, the objects' other characteristic, from the perspective of sensorial perception,
is their materiality, i.e., their texture and colours; consequently, the rhetoric aug-
mentation of the textures of a virtual object could create tactile sensations similar to
the ones generated by a real object (see Brogni et al.
2011
: 235ff).
This is the reason why the attributes of objects in the reconstructions of every
level of dwelling were emphasised, and data bases with the textures and colours of
the specific materials were made, to evoke the tactility and colours of the ancient
dwelt spaces. For example, for the prehistoric period, the database contains the
colours of the local dye plants, soils, ceramics, flints, woods, hemp, charcoal, wool,
and many other materials from the archaeological record and ethnographic sources,
together with the coloured textures of these materials.
Collages with JPG images extracted from these databases are overlapped on
the images of the interior of the wattle and daub prehistoric house when one
points the mobile phone to a coloured or textured surface. The IT application was
designed to identify these attributes of the objects. Here again the AR technology
