In this talk a number of problems are considered which are related to the modelling of eye guidance under visual attention in a natural setting. First, from a brief and crude discussion of a variety of available models spelled in probabilistic terms, we show that current approaches in computational vision are hitherto far from achieving the goal of an active observer relying upon eye guidance to accomplish real-world tasks. Second, we argue that this challenging goal requires to embody, in a principled way, the problem of eye guidance within the action/perception loop, In particular we will consider the issue of how to design specific oculomotor priors (oculomotor tendencies, biases) and how this endevour can be accomplished in the framework of animal foraging models Eventually, to give some idea for future studies and directions in the field, we discuss the issue of facing the inextricable link tying up visual attention, emotion and executive control, in so far as recent neurobiological findings are weighed up.
