Abstract: In qualitative motion representation, frames of reference
play an important role as well in measuring of the motion
data as in representation and application of algorithms.
This paper discusses motion representation in egocentric
and allocentric frames of reference and begins with some
general considerations on motion representation through
qualitative distances and directions that apply to both
technical and biological systems. An approach that
involves numeric generalization of a numerically represented
motion track and subsequent transformation in a qualitative
representation has advantages for technical systems, though.
Last, algorithms for generalizing qualitatively represented
motion tracks in an egocentric and allocentric frame of
reference are presented.
