units in the proposed model. When operating in the run mode, the knowledge
base may be directive in the following situations, as for example:

- apriori information, important information already known.
- run time information, dynamic changes to achieve the goal.
- restrictions or limitations, arising in the measurement process.

The proposed interface approach is considered to be straightforward with a
minimum of built-in conflicts, as described above. This model approach as shown
in Fig. 5.8 can be refined as a modification of the basic structure according to the
previous picture, and illustrated in Fig. 5.9. The interfacing processes are defined
and human relation involved in the system has been considered.
The above perceptual model approach can be seen from different behavioural
perspectives and may be related to fields in biology, computer science or engineer-
ing when relating to the artificial perceptual sensor system perspective. The three
following angles of approach are concerned when providing the view of a percep-
tual model comprised in an artificial sensor system. This aspect of the model can
be illustrated in the following three perspectives:

a human-related perspective.

an artificial perceptual sensing systems.

•

a computational perspective.

The sub-processes of the perceptual model approach can also be related to a
technology point of view. The illustrative aspects are structured in general terms
and described in further detail below:
