images and sounds. Due to stereotaxis it is connected with a lot of mathematical calculations.
Sometimes there are calculations made in real time. In some cases the calculations are made before
the right screening.

Artificial environment can be similar to real world. Simulations which are handy for pilots or military
trainings are created as well as models of renovation, construction and medical works. Their virtual
scenario is created in difficult or even extreme and untypical conditions, but they are safe for our
health.

There are also mathematical models the world climate which are useful for the weather forecast.

An implied form between the virtual and real world is the Augmented Reality (AR) , introduced later
than the virtual reality. It is connected with enriching the real environment by the contents made by
computers which is completed mainly by graphical contents.

R. Azuma identifies RR as a system which connects the real and virtual world, interactive in the real
time, allowing the freedom of movements in three dimensions. Augmented Reality does not create
new, fully virtual three-dimensional world, but it completes real world (which does not change) with
new images or information (virtual surface) .

We deal with AR when we observe the surrounding world with a smartphone or a tablet but it has
graphical elements added.

In the basic version it means a possibility to watch a film, animation or sound with the help of a
suitable app and gadget (a tablet or a smartphone) after pointing a tag which releases multimedia
message. A tag – marker – it is a graphical material (graphics, picture, text or a different thing) which
activates multimedia message (film, animation, audio folder, slideshow).

Technology of Augmented Reality in an advanced version allows an interaction with digital image or a
3D object, for example a virtual person we touch on the screen and who reacts to our gestures,
answers our questions, etc.

How does AR work? A camera records a real image, then it passes it to an app (users can usually use
their own device having downloaded a special app). The app looks for programmed patterns in the
image (markers), then it adds extra graphical elements to the observed image, creating the AR which
is seen by the user.
The base of AR system performance is discovering and following chosen points (graphical markers,
natural objects such as buildings, objects or different identification points) I the real world in order to
put virtual objects on it. A camera follows the marker movements and a computer displays a 3D
object created in a real time with the use of any projection medium.
