for the human perception to receive, e.g., when driving a car. Further, data can be
applied to the senses in such a way that even if we know that the human capability
in this specific sensing mode is not perfect, we overestimate the perceiving data
and miss important information, as when for example, driving in the dawn. There
is a consensus in the literature that, the human hearing frequency spectrum whose
performance generally decreases with, e.g., age and diseases. This quality is also
valid for the olfactory sensing, which normally changes with age. Obviously age
is one of a variety of important factors for exhibiting permanent decreased percep-
tion, which is also considered to be a major instant association, that excludes a well
representation in a population. These people will most likely not be on an equal
level of conditions in experiencing life. The emerging new advanced technology
that is constantly introduced to the market does not, however, provide a perfectly
adapted solution for each individual's specific discrepancies.
The virtual reality programs shown in computers, televisions or professional
movies do not, for example, consider the degree of astigmatism that parts of the
human population suffers from. The astigmatic error causes a feeling of seasick-
ness appearing when interacting with a virtual situation and the experience of vir-
tual beauty is therefore blown away. Vitale (2006), has conducted a study between
1999-2002 and presented that, refractive errors are common in the United States
population. The study reported that more than 110 million Americans could or do
achieve normal vision only with refractive correction. Obviously, there seems to
be a number of individuals, who like me, are not able to enjoy the activities that
can be found in computer simulators or three-dimensional movies.
The advanced technical systems for enjoyment that we experience today gen-
erally do not meet the expectations that a huge part of the population usually
require. One main explanatory reason may be that the system normally does not
interface with the requirements that our individual perceptual sensing system
exhibit. In this topic, there are also arguments provided that demonstrates different
specific based unique and independent thresholds of the perceptual performance
abilities, which make this perceptual capacity highly individual. To expand this
reasoning, the dog of the family has a completely different experience in sensitiv-
ity and perceptual thresholds. The family animal has obviously another opinion of
what is enjoyment in music or appetising odours in the environment than probably
the rest of the family.
The revealing conclusion drawn from this exposition is that we probably do
not comprehend the world in a similar way as other spices, or even between
individuals. The fact may be annoying that there could be another world there
outside, where animals experience another interpretation of the environment and
explore in a different manner than humans. Other spices may then experience a
more beautiful world than we ever can imagine by using other complex sensing
abilities. Some animals have during generations refined the perceptual process,
adapted and developed techniques to find an advanced and optimised perfor-
mance in order to improve their sensation capability. Since the prerequisite of
survival in the environment is crucial, then the condition and development phase
