person, Van den Stock (2007). The response may be a feeling of welcome, sus-
picion, attraction or disgust depending on the response received by the encoun-
tered body perception. The topic on body recognition indicates that that there is
an overwhelming direction towards face recognition in the literature. An emerg-
ing interest is to explain a person's stationary mode and in some sense also the
person's intent by identifying their behaviour. For example, security personnel
are trained to identify bodily behaviours and follow a set of cues that are incon-
sistent. The abnormal behaviour of a person acting strange by showing a ner-
vous, calm or moving in a certain pattern structure may create an increased and
suspicious interest from artificial, intelligent and distributed surveillance systems,
Valera (2005). These examples certainly illustrate the circumstances that by apply-
ing our intuitive understanding, as a measurement for a distinct identification of
body language, will simply not be enough. To establish a person's characteristic
body language, we need to explore more dimensions in order to identify a person's
behaviour, by identifying an abnormal body language.
The technical advances in camera supervision of travellers in airports, the in-
dividual behaviour pattern in a crowd or in specific areas has been of emerging
interest and systems have been developed, which have also been reported in the
literature, e.g., Valera (2005).

3.2.2.4 LACK OF PERCEPTUAL SENSES

In the daily life, we exhibit an extensive but still highly normal interplay with the
world around us, gather information about our surroundings and interact with it
