Imagine a person navigating on the trackball of a mouse - it would need full body control. In this article we describe the Virtual Balance, an input device for a responsive virtual environment. This device is driven by weight shift on a small platform and does neither require special training nor wearing uncomfortable equipment. The Virtual Balance aims at intuitive navigation through complex 3D space. It can be used to skate or fly like on a magic carpet through a virtual world. With shifts of body posture the navigator controls speed and direction of his/her movement in the model world, which is calculated from the changing pressure on three weight cells under the platform. Different fields of application are presented, showing scenarios already realized as well as a variety of possibilities for future use.

This paper presents an overview on and reports on early experiences of the European ACTS project AC089 called „Distributed Video Production (DVP)“ which started in late 1995. Central to DVP are distributed pilot applications for professional digital video production over ATM broadband networks (LAN and WAN). Distributed video production refers to situations where the cameras, recorders, switches, mixers and other equipment used in video production (or post-production) are located at several sites linked by high bandwidth network connections. The DVP project investigates requirements of broadcasters for several forms of distributed video production and runs a series of trials of distributed virtual studios, distributed rehearsals and remote video editing and retrieval. Together with North American partners a transatlantic broadband ATM link will be tested for distributed virtual reality simulations. This paper reports about two initial tests with a German public broadcaster and the German Telekom. DVP project partners are GMD and about 20 broadcasters, computer and video equipment manufacturers, and video production companies. More information can be obtained from http://viswiz.gmd.de/DVP
Distributed Video Production
(1996)
Video production is inherently distributed: Broadcasters are physically distributed over several sites and studios, they increasingly outsource video production and post-production to specialized studios or upcoming virtual studios. Thus there is an increasing demand for the enabling technology for distributed video production.
