In contrast to the advanced sensors systems of today, compared to the
simplicity of optical means to correct the eye lenses, we have nowadays gained
a technology development that are able to detect long distance behaviours. Cam-
era systems can visually be in a remote place at a distance from the body and the
substantially increase the perceptual performance of the eyes. This revolutionary
technique may not provide a general increased performance, but truly comple-
ments the human visual ability in its neighbourhood. In the following section, two
illustrative examples that demonstrate the value of complementing the human vi-
sual sensing system, will be given. The examples are taken from a general situation
where the human vision alone is not able to cope with effective perception ability.
When travelling faster than earlier generations before has adapted into its nat-
ural habitat as illustrated in Fig. 6.4, we simply cannot expect that our perception
will be able to cope with various situations, e.g., when driving a car at high speeds,
for example higher than 100 km/hour. The driver has to divide her driving atten-
tion between attention e.g., manoeuvring driving functions or comfort functions
as the music player. Further, in such situations there is a world outside the car that
the driver has to relate to and manage. The rate of environment situations change
frequently and is challenging, e.g., other traffic, lights, roads and lanes. The driv-
ing situation will indeed give rise to the view of the driver's capability and how
much information a human may cope with in high speeds when managing arising
and changing situations. If a person has to cope with the environment but when
two occational targets happen in parallell then each of them requires to be han-
dled with a separate response. Furthermore, if the two targets in the environment
are detected in a rapid succession, then the response for each, or both of them are
delayed because the brain is only able to initiate one action to each of them in a
