Live Tuning of Virtual Environments: The VR-Tuner

Abstract

This paper describes a solution for the modification of virtual environment (VE) applications while being immersed in the application scenario inside of an immersive projection environment. We propose an infrastructure which enables developers to adjust object properties and change the structure of the scene graph and data flow between nodes using a tablet PC. The interface consists of a two dimensional graphical user interface (2D GUI) brought on a spacial aware touch screen computer, accompanied by a mixer console with motor faders. We discuss the usability of the combination of different interaction modalities for the task of tuning of VE applications.
