From virtual reality to augmented reality
1.1 Virtual reality and virtual world
Virtual world (VW) is a world with artificial elements all generated by
computer according to virtual reality (VR) techniques. VW is made of virtual
entities that are programmed to stand as functionally equivalent to real ones.
VR turns out very effective to simulate environments uneasily accessible
in real world. It is low cost, risk free and safe, and it is capable of
implementing huge environments, as in astronomy, as well as very small
ones, as in the case of cellular systems. VW can simulate dangerous action
sceneries for flight, fire, contaminated areas and so on. VR allows us to face
and solve problems which are often without other solution and gives us the
chance of getting operation abilities or observing simulated behaviours.
New VWs could include abstract entities, such as logical elements,
reasoning, grammatical and syntactical forms, thus enabling us to face the
ambit of word and thought. It could include psycho-motor faculties and
define new interaction types up to new alternative communication forms.
VR can manage economic-financial values and turns out very useful
when it is difficult to guess how a share may behave in selected conditions.
It will be much easier to study a share trend in a virtual environment that
is specifically arranged to observe its interaction with other shares or to
formulate a new understandable model.
Dealing with art, VR can create virtual relationships between space and
music to manipulate sounds in space rather than in time, or it can manage
pictures and let us navigate into a hypothetical 3D projection.
