Abstract:	The classification of complex courses of motion and their 
		prediction, for example in cases where collision should 
		be prevented, are important properties for advanced 
		monitoring systems or mobil agents like robots, intelligent 
		vehicles etc.
 		By taking the human visual system as a model we want to 
		derive conclusions regarding the representation, processing
		and prediction of courses of motion. Therefore, 
		psychophysical experiments on the limits and
		capabilities of the visual system to deal with dynamic 
		information should provide evidence for the
		modeling of two different stages: a higher level, language 
		oriented stage and a lower level, perception orientated 
		stage. The higher level stage will be modeled by 
		a qualitative representation, whereas the perception 
		oriented stage will be specified by a spatio-temporal 
		memory model.
		A major point of our research interest concerns the possible
		interdependencies between these two modeling stages, 
		like relationship between the representational requirements
		on a short term memory range and qualitatively expressed 
		motion information.
