The problem of human machine dialog deals first with the misunderstanding problems: it is more important to build a system able to dialog, even with a partial understanding level, than to build one having a high understanding level, even including the user's goals, plans, beliefs and background knowledge. We consider that the task of a dialog module is to avoid breaking off of communications as much as possible through the use of a dialog strategy. To this purpose, we describe a model using two axes and a set of variables to build a graph allowing any dialog state to be situated m a metric space at any time. Due to the model, the system may control all dialog phases to avoid some critical zones or, as a last resort, be award of their proximities.
