-The availability in 2021, on the pro-consumer market of standalone (un-tethered) Head Mounted Displays (HMDs) for Virtual Reality (VR) and Augmented Reality (AR) is an enabling technology in the field of cognitive psychology of the human visual system. It is of special interest in forensic sciences where one need to reconstruct the characteristics of an observed phenomena from a witness testimony.+Pierre Lagrange y fait référence à la fin à Inforespace de Décembre 1978, mais je pense qu'il fait référence au {{:simovni2:inforespace_hors_serie-no_03-1979.pdf|Inforespace Hors Série #3}} de Décembre 1979 avec l'article (à charge lourde) de Dominique Caudron p14-p38.
  
-This article tries to list the known issues to which investigators have been confronted +The paper trail shows Dominique Caudron was the first in France to build a practical device around 1974.
-; the new issues raised and which parameters are now measurable. We also list the expected practical limitations of the current state of the art.+
  
-Such HMDs allow for much easier measurement of some characteristics of the human visual systems. Some issues existing in more previous methods are circumvented, new issues arise. +Dans un article dans [[simovni2:caudron|OVNI Approche #22]] en 1980, Dominique Caudron décrit le Simovni.
