Flexible, interactive, graphic user interface has choice possibilities for user projected by image projection on rear side of semi-transparent screen

摘要

The flexible, interactive, graphic user interface has choice possibilities for a user projected by image (2) projection on the rear side of a semi-transparent screen (3), combined with scrutiny of the position of a light reflection with increased luminous intensity, also on the rear side of the screen, occurring as the result of a finger (5) or indicator device on the front side of the screen.
