The Power of Space and Time – how spatial and
temporal structures can replace computational effort
Christian Freksa
University of Bremen

Abstract
Spatial structures determine the ways we perceive our environment and
the ways we act in it in important ways. Spatial structures also deter-
mine the ways we think about our environment and how we solve spatial
problems abstractly. When we use graphics to visualize certain aspects
of spatial and non-spatial entities, we exploit the power of spatial struc-
tures to better understand important relationships. We also are able to
imagine spatial structures and to apply mental operations to them. Sim-
ilarly, the structure of time determines the course of events in cognitive
processing. In my talk I will present knowledge representation research
in spatial cognition. I will demonstrate the power of spatial structures in
comparison to formal descriptions that are conventionally used for spatial
problem solving in computer science. I suggest that spatial and temporal
structures can be exploited for the design of powerful spatial computers. I
will show that spatial computers can be particularly suitable and efficient
for spatio-temporal problem solving but may also be used for abstract
problem solving in non-spatial domains.

Short Biography
Christian Freksa holds the Chair of Cognitive Systems at the Faculty of
Mathematics and Informatics at the University of Bremen, Germany. His
research concerns representation and reasoning with incomplete, impre-
cise, lean, coarse, approximate, fuzzy, and conflicting knowledge about
physical environments. Particular emphasis is on qualitative spatial and
temporal reasoning. Freksa received a PhD in Artificial Intelligence from
UC Berkeley. He carried out research at the Max Planck Institute and
at the Technical University of Munich, at the International Computer
Science Institute in Berkeley, and at the University of Hamburg. In 2002
he initiated the International Spatial Cognition Quality Network and the
Spatial Cognition Research Center in Bremen and Freiburg that he has
been directing since 2003. Christian Freksa is a Fellow of the European
AI society ECCAI.
