The manually selected data obtained when testing food products may be
increased by experimental design. Computer programs are able to significantly
increase the possibilities of extracting useful information from the data. Initial data
from the experiment design is used to test the best possible experimental plans that
explain the trend of the experiments. It is, however, beyond the scope of this topic
to penetrate deeper into the fundamentals of experimental design. Further details
on this subject can be found for example in Esbensen (2000).

5.5 THE HUMAN IN THE LOOP OF FUSION

From the previous sections, we may draw a not too controversial conclusion that
in many cases the use of the human sensing organs is highly competitive in
sensory analysis. The human ability, in acting as a perception unit in a complex
measurement system including artificial sensor systems, is still in frequent appli-
cations convincingly competitive and in many cases an effective solution. The
human participation, as a sensing unit in a measurement loop, is in many situa-
tions of importance for the overall measurement system performance, especially
when humans contribute with highly complex and advanced qualitative input. In
even more involving activities, human capacity is normally highly directed in the
analysis and decision-making process, providing the human intelligence and sens-
ing capabilities. This argument is often needed in complex measurements.

5.6 APPLICATIONS

Applications, where the human is interacting in the system loop can be frequently
seen in daily activities. Specifically, three specific procedures can be mentioned as
