Abstract [en]

This  paper  describes  a  solution  for  the  calculation  of  the  correct  stereo  pairs  of  a  Mirror-Based  Augmented   Reality System (MBARS).To achieve augmentation half-silvered mirrors are applied due to their dual reflection characteristic that allow simultaneous seeing-through of real objects and the viewing of reflected virtual ones. This way it is possible to merge virtual content reflected by the mirror with real objects that the user can see through it. The virtual con-tent can be either generated by a monitor or a projector. In this paper we will only refer to the monitor-based systems. These systems are view dependent, meaning that depending upon the viewer’s position the reflected im-ages have to be recomputed. This is why a Head-Tracking System is needed to supply the current viewer’s posi-tion. Also we need to consider the main system components and there location, to correctly compute the stereo pairs. Furthermore we present how the result of the mathematical calculations can be used in combination with com-mands of the OpenGL API to achieve the desired transformations and to allow interactivity.
