Cartesian model of thinking request certain norms difficult to apply in psychiatry. We consider much interesting to realize informatics programs aimed to defining clusters of pathology in a different manner than medical judgment. These clusters must be defined by experts (psychiatrists) familiar to the geographic area and the socio-cultural characteristics of it. In concordance with these conditions, the diagnosis must be viewed as a variable distance from the center of gravity area of cluster that defined certain disorder. Also, the course and prognostic must be consider as status modification vector during the serial investigations and the normal status is considered to have more typologies but in essence to represent a liberty of movement in behaviour's space with a correspondence between the input and output status from the psychic's system. The probe itself will represent a paraclinic measure to support the doctor's experience and to argument the diagnosis and to follow the treatment evolution.

The paper continue the workshop presented in Nice, last year, where we presented the automatic analysis of gait, voice, gestures, writing, etc.
