In this paper, we describe a physical input device for the control of virtual cameras. The so called RoundTable has a round projection area where physical icons are used to stipulate the position of virtual cameras. With this scenario we propose a hybrid mixed reality environment for use by production personnel for real-time camera control during a live-broadcast. We present first results of using the RoundTable to support the managing of events in electronic arenas and compare them with traditional interfaces for camera control. We also comment on findings from a scenario in the field of sound mixing and sound composition.

Immersive projection technologies such as CAVE can generate a high presence virtual world. However, it is difficult for the user to experience the immersive virtual world in the real workplace, such as the design room or the conference room, because this type of display system requires a large space in order to install the screen. In this study, an invisible interface was developed for the immersive virtual world by integrating a transparent immersive projection display and cellular phone interface technologies. By using this system, the user in the real world can experience the high presence virtual world in an immersive environment. This system was applied to several fields of application, such as augmented reality and telecommunications.

Virtual reality offers completely new possibilities for collaborative work over distributed environments. To enable collaborative work, it is necessary that both, virtual objects as well as the other users, can be seen simultaneously in real-time. A novel technique is necessary to overcome the contradiction of darkness and light for image projection and video acquisition, respectively. A stroboscopic light and a camera system are added to the existing VR-system and a few modification are made to existing shutter glasses. In such a solution, the method of projection in the VR-system remains unmodified. This paper describes how to resolve this contradiction with the constraint to make as few changes as possible to existing VR-systems. Furthermore the timing of the different devices is discussed.

Over the last few years the number of industrial immersive projection technology (IPT) installations has grown rapidly. Most of these systems are powered by one or more SGI Onyx graphics computers with several independent graphics pipes and quite a few CPUs. Since these machines represents a big investment, many installations are designed to make use of the Onyx graphics power at different presentation areas and meeting rooms. In this paper we will introduce a new client/server approach for controlling such distributed IPT installations where multiple presentations and work sessions run simultaneously and where different users access the resources of the facility in parallel. We first discuss the necessity of multiple configurations of the IPT hardware for different kinds of presentations and applications. After this, we explain the special requirements for the control of distributed multi-user Reality Center s ( Reality Center is a trademark of SGI). We then present the client/server architecture of our new Reality Center management software (RCMS). Finally, we will give an outlook for possible future extensions of the software to meet individual requirements.
