through our actions. The interaction between perception and action is complex
and of high performance. On the other hand, the perceptual information is the
basis for decision making and therefore sensitive for a proper reactive action abil-
ity. Perceptual deficits are often devastating in the overall performance and may
lead to the obvious deterioration in decisions and response action, which in the
long run also have an influence on the survival impact. An example concerning
manipulation of the haptic perception in virtual environments is presented in De
La Torre (2008).
We recall that the human sensing is among the last functions that abandon
us when there is a life-threatening situation and danger to the body. Even when
we are unconscious, the sensing abilities can be functioning. This quality may
be a heritage from the past, where the body focusses on vital organs when the
body is life threatened in a critical situation. Therefore the allot of sensing abilities,
regarded as vital function of the body's survival nature is convincing where the
perception abilities seems to be of high priority.
Medical tests have showed that if we close the perceptual sensation and pre-
vent most of the sensory inputs entering the organs, then we are lacking the es-
sential information to be able to act normally in the surrounding and in actual,
we cannot handle the normal situation in life. The person, after lacking essential
sensing input information, begins to fill in the information gaps by hallucinating.
This situation to deliberately get rid of a person's sensing abilities by outmanoeu-
vre perceptual organs has frequently been used, e.g., in prisons. The individual is
deprived of his contact with the environment and the world reference frame gets
fuzzy. This mode creates internal thoughts about “where am I, what is around me”
and when it is constantly dark, the individual may loose time reference. Then, if
the aim is to increase the confusion by adding external sensory information, e.g.,
sound, smell or light disturbances in close contact with the person, in order to cre-
ate illusions that can be related to earlier experiences or unpleasant situations. The
breaking down of a person's perceptual intimate, which may also be its fundamen-
tal relation to the surroundings, is considered of high internal security, that easily
can be affected by manipulation in forms of depriving a person by artificially af-
fecting their sensation and by tampering with their perception, Reynolds (2008).
The result might be devastating for the individual by affecting the interference of
the perceptual structure that may create long-term effects on the human mental
health.

3.2.2.5 INCREASED SENSORY PERCEPTION

The human sensory abilities are highly dynamic and complex. Perception is highly
effective and normally not performed in a static mode. The normal perception
when exploring our environment is that we move our sensory organs, head and
body at different distances in such a way that the sensory information is adjusted
to the present situation. The perception then has to follow a co-ordinated pattern,
e.g., looking at the person who talks, getting closer when listening to a person in
a buzzing environment, etc. The complex co-ordinating structure is redundant in
