In this paper we present a framework for research into the development of an Active Observer. The components of such an observer are the low and intermediate visual processing modules. Some of these modules have been adapted from the community and some have been investigated in the GRASP laboratory, most notably modules for the understanding of surface reflections via color and multiple views and for the segmentation of three dimensional images into first or second order surfaces via superquadric/parametric volumetric models. However the key problem in Active Observer research is the control structure of its behavior based on the task and situation. This control structure is modeled by a formalism called Discrete Events Dynamic Systems (DEDS).
