-====== Introduction ======
-The availability in 2021, on the 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 observed phenomena from on a witness testimony.

-Such HMDs allow for much easier measurement of some characteristics of the human visual systems. Some issues existing in more basic methods are circumvented, new issues arise.
+----
-This article tries to list the known former issues, the new issues raised and which parameters are now measurable.
-===== Parameters Considered =====
+**biblio (in progress)**
-We are here specifically interested in the estimation of
-angular size
+===== SimOvni History =====
-angular height

-luminosity / brightness
+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.
-angular speed
+The paper trail shows Dominique Caudron was the first in France to build a practical device around 1974.
+Dans un article dans [[simovni2:caudron|OVNI Approche #22]] en 1980, Dominique Caudron décrit le Simovni. (Source : SCEAU / Archives OVNI)

-We already know that some parameters are very often highly mis estimated by witnesses. This includes the angular height, angular size, angular speeds, durations.
+=====Cognitive psychology=====
-These problems are known for over a century ((camille flammarion)),
-yet, we feel that there is currently a huge lack of characterization of the biaises in the reports.
-Some tentative studies were done, but with a lack of control and strict definition of the setup ((german study)).

-there is a risk of altering the response in a non detected way.
-For instance,

-  alteration by the looking though an eye piece
-  alteration by looking through a window, depending on the distance to the window
-  alteration by the use of an object held by hand for comparison.
-  alteration by being sitting or standing.
-  alteration by the emotions felt.
-  alteration by the visual context around the object observed
-  alteration by the location of the witness : inside, outside of a building.
-This can alter the estimations of
-  angular size
-  angular height
-  luminosity
-  angular speed
-New interesting developement :

That figure is the one of interest for our measurements of the brightness of the display. (@ 1000 lux from outside, you get 10^2.48 = 302 lux behind the visor, hence the 30%)
