Perception proximale et distale \`{a} l'aide du dispositif de Lenay
  We present in this article experimental results obtained with the "dispositif de Lenay" : for a localization task (distal perception) and an orientation estimation task (proximal perception of the orientation of a cylinder in a plane). In this last experiment, a "virtual" version of the Lenay device was used. Results are here used to illustrate methodological and theoretical proposals for the study of cognitive and sensori-motor processes involved in perception.
