Judged Distance to Virtual Objects in the near Visual Field

Abstract

Errors in judged depth of nearby virtual objects presented via see-through, helmet mounted displays are examined as a function of monocular, biocular and stereoscopic viewing conditions, accommodative demand and subjects’ age. These errors are argued to be related to changes in binocular vergence. Suggestions for improved control of the judged distance to virtual objects and the cause of the judgment errors are briefly discussed.
