American hotels are equipped to allow a mother on a business<br />
trip to eat together with the husband and children at the<br />
house, making the co-presence through systems of video conferencing<br />
on a computer and with the possibility of ordering,<br />
through Internet, the same pizza in the same chain of home<br />
delivered pizzas. The orders will be sorted automatically in<br />
such as way that the pizzas are delivered in a synchronous<br />
manner and the whole family can eat together.<br />
Also interesting are the evolutions of the systems and technologies<br />
that allow one to enjoy visualisation on the move,<br />
from the best screens for the mobile phones to the systems<br />
of visualisation through glasses or screens based on reflections<br />
of light. The systems of visualisation that use the lenses<br />
of glasses are interesting, as they stimulate applications of<br />
mixed reality, that is to say those in which the vision of the<br />
real world is superimposed, when needed, artificial images (as<br />
already happens in training pilots of planes).<br />
Screens based on the reflection of light, such as those that<br />
use e-Ink technology, have the characteristics of sheets of<br />
paper. That is to say, they take advantage of the light present<br />
in the environment to make information visible. If we<br />
try to use a portable computer on the beach, we will discover<br />
that the screen is practically illegible: the competition<br />
with sun light is too uneven. On the other hand, if we take<br />
a notebook and try to read it in a dark room: there is not<br />
sufficient light “to see”.<br />
With e-Ink we have on the screen the same characteristics as<br />
a sheet of paper, with an additional advantage of having images<br />
in movement. These new “books” open interesting prospectives:<br />
we obviously think of a text book to teach English.<br />
After a page of grammar it becomes natural to open up a<br />
conversation with a point of the earth in which one can interact<br />
with those who speak English, jumping perhaps from<br />
New Delhi to Adelaide to realise how that simple “Hello” is<br />
transformed according to the place. To learn is transformed<br />
according to the places. To learn therefore becomes an involving<br />
adventure, because it signifies testing ourselves with the<br />
world, and not only with a teacher.<br />
IDENTIFICATION AND LOCALISATION TECHNOLOGIES<br />
Over the years a variety of technologies have been adopted<br />
to allow the localisation and identification of objects and<br />
persons, with motivations which go from the increase of<br />
efficiency to safety. The technology family, which goes under<br />
the name of RFID tag (Radio Frequency Identification),<br />
should crowd out, substituting them, the bar codes used in<br />
the majority of cases. Not only. It should also permit the application<br />
to other categories of objects, such as, for example,<br />
information.<br />
There also exist other technologies applicable in specific segments,<br />
for example, the labelling for fixed objects: in future<br />
it will be difficult to find an object that is not unequivocally<br />
identifiable.<br />
With the presence of a tag (label) in every object and the<br />
parallel presence of detectors of tags in a variety of devices,<br />
starting with mobile phones, an extremely interesting market<br />
is opened up, to which some attribute the name of Information<br />
Wrapping (Wrapped up with Information). In practice to each<br />
object that has a tag there corresponds an amount of information<br />
present on one or more sites, management by one<br />
or more organisations, which it is possible to access starting<br />
with the object itself.<br />
In Japan this technology is used to charge telephones with<br />
virtual money, leaning it upon an ATM machine and then<br />
using it, always in the same way, money, leaning the telephone<br />
on the cash machine at the desk of a supermarket.<br />
Another lot of technologies, important and very near that of<br />
identification, are that of localisation. Today we have systems<br />
of satellite localisation GPS (Global Positioning System), tracing<br />
through electronic boe that intercept special transpon-<br />
