M.3.6 Abstract feedback loops around ‚Here and Now’
The figure visualizes the dynamic vision process around the point ‘here and now’: Expectations, stored knowledge about motion processes of objects, and feedback into the perception process are key. [Dickmanns 2007, p.17]
A diverse collection of
sensor data with different time delays and noise characteristics has to
be interpreted in a coherent manner taking knowledge about classes of
objects, their individual variations, and about own motion characteristics and
maneuvers performed into account. In humans, the extended presence is in the
order of a few seconds.
In
vertical direction the amount of internal representations for
a) processing of sensor
data exploiting background knowledge,
b) the generation and
testing of object hypotheses,
c) preparing and
implementing adequate actions,
d) computation of
expectations, and
e) the extraction of
new knowledge
is sketched qualitatively with a maximum
at the actual point in time.
„Understanding“ of motion requires knowledge about typical maneuvers of other agents and knowledge of situations when the maneuvers may be used to advantage.
