Mixed Reality Experience - A brief introduction to VR using a Virtual (TV) Studio [DE]

The production with the title "Mixed Reality Experience - A brief introduction to VR using a Virtual (TV) Studio" was part of the master course module "Interactive Virtual Studio" at the HS Düsseldorf, University of Applied Sciences and took place at the Studio from vr3 / Voss GmbH – TV Ateliers. The idea for the production was inspired by the interview and demonstration at the public TV program WDR Lokalzeit at 10.11.2016 with the title "Willkommen im Virtual Reality-Café". The goal was to use a virtual tv studio, enabling egocentric and exocentric views within the virtual environment. The set shows a part of the SteamVR application "The Lab", demonstrating interaction and navigation. A brief introduction to VR defined by imagination, immersion and interaction is given. The shown composition of real and virtual objects is called "Augmented Virtuality". The actors demonstrate the possibilities of interaction by playing with balloons and moving a cutting plane through a medical human scan. The camera tracking system Startracker (Mo-Sys) was used with the Tracking Hub (Vizrt) software using an OpenVR driver, enabling the production without modifying the VR application. The hardware keyer from Ultimatte was used for image processing such as removing the background and mixing. The question “How can the experience or use of a virtual environment be shown to a third party using a live stream or recording?” was the main focus.

Adapter for Vive Controller

 

Adapter für Vive Controller Advantages and Limitations of Immersive 3D Polygonal Mesh Modelling in Virtual Reality

For first experimental shots, an adapter was designed by Denis Herder and 3d printed. The model of the adapter can be used freely, but fits only for one version of the vive controller. The video clip for the master thesis Advantages and Limitations of Immersive 3D Polygonal Mesh Modelling in Virtual Reality from Philipp Ladwig was produced with a similar technique.
