SYSTEM FOR ADJUSTING LOCATION IN AN IMMERSIVE VIRTUAL ENVIRONMENT

摘要

System (30) enabling selection, in an immersive virtual environment (11), comprising a 3D display system (17) able to display a graphical selection-enabling element in a region of a virtual control surface; a system (18) for locating and detecting the movements of the head of a user and of a pointing means (22) held by said user, said selection-enabling system (30) comprising an interface able to detect the position of the pointing means with respect to said virtual command surface, and its approach with a view to reaching a selection-enabling zone (33) of a selection-enabling graphical element (31), characterised in that the interface is able to modify the selection-enabling zone of the selection-enabling element (31) while keeping the display of said element (31) unchanged, when the position of impact of the pointing means (22) with the selecting-enabling element on the command surface differs from an actual position of the selection-enabling zone by an amount smaller than a threshold.
