Virtual reality can be extended to create a collaborative distributed environment over a physical network. Such an environment can only be established however, if both, virtual objects and the other users, can be see simultaneously in real-time. This requires a novel technique to overcome the contradicting requirements of darkness and light for image projection and video acquisition, respectively. In order to make an inexpensive and easy to build solution, a camera acquisition system and a stroboscopic light are added to the existing VR-system. Modifications are made to existing shutter glasses to handle simultaneous projection and video acquisition. In such a solution, the method of projection in the VR-system remains unmodified. The poster describes how to resolve the conflict between the darkness required for projection and sufficient lighting necessary for video acquisition.
