Multiuser VR

The aim of the project is to develop a versatile co-location multiuser system, with which several users can dive into virtual worlds together in the same room. The system can be used for many different areas. As a multiplayer game in which the users feel even closer to their fellow players through increased physical presence. As a virtual film set to try out camera movements or interactions of actors without much effort. Or as an interactive experience that transports the user into a new dimension of immersion.

An iPad also serves as a window into the virtual world. The user can use this virtual camera to move through the room and in some cases even interact with the virtual world. The virtual world can also be placed on an interactive screen. This gives outsiders the opportunity to change the entire scene.

The co-location multiuser system can be used wherever the headsets can connect to a network thanks to the Mobile VR-Headsets. The system is developed by IA-Space staff members Chris Elvis Leisi and Oliver Sahli.

Home in the Distance

Home in the Distance is based on a short story, written by director and VFX artist Andreas Dahn when he was about 17 years old. In his residency at the Immersive Arts Space he made an animated short film and an interactive VR experience out of it, and applied unique methods of Virtual Production. In contrast to the traditional animation and VFX workflow, which is heavily based on storyboarding and previsualization, the conscious decision was made to leave out these steps, in order to find out if new technologies make it possible to create a more emotional and spontaneous film experience.  

Andreas Dahn first constructed the locations, his character and all other digital assets in 3D. With the help of Motion Capture technology he animated the complete story. And finally he shot the 2D film with a virtual camera that he operated in the 3D space with VR goggles. So, he literally shot the film in the virtual space. After the 2D film was finished, Andreas made an interactive VR experience based on the same 3D assets and the same story.

The character was sculpted by hand with dough and photogrammetry was used to create the virtual 3D model. Rigging was done with Human IK in Autodesk Maya. Students from the 3D Akademie Stuttgart helped to model the set and props. In addition, an actor`s performance was motion-captured with OptiTrack in the IASpace at the Zurich University of the Arts (ZHdK).

The camera work was done with a VR tool, developed by Mirko Lempert (Stockholm University ot the Arts) and Simon Alexandersson (Royal Institute of Technology, Stockholm) and rendered in realtime in Unity.

Together with visual artist Tobias Gremmler, choreographer Nadav Zelner and set designer Mariana Vieira Gruenig, students of the Contemporary Dance program at the Zurich University of the Arts explored the connection between real dancers and virtual characters in a modular stage design.

The prototype presentation took place during the REFRESH #2 conference on Thursday, September 26th.

# Keywords: Motion Capture, virtual characters, real-time performance, projection mapping, augmented reality.

TwinLab (Pilot, 2018)

For several years now, the ZHdK has maintained a lively exchange with cultural and educational institutions in Hong Kong. On the occasion of an official visit to the ZHdK from the head of government of Hong Kong, Chief Executive Carrie Lam in January 2018, temporary partner labs were set up in both cities. The goal was to promote interdisciplinarity within a framework of research and development into technology-supported arts.
The resulting TwinLab project is premised upon the availability of the same technical infrastructure at both locations. The cooperation can thus be based primarily on data exchange and be sustainable. Real-time transmissions allow for synchronous experiments and productions.

The first TwinLab project “The Hidden Formula – The Heavenly Palace” was developed in cooperation with the experimental theatre group Zuni Icosahedron which is based in Hong Kong and the two performances could be experienced simultaneously in both locations. The movements of the dancers were recorded at both locations using motion capture technology to create real-time visualizations in a video projection. Despite the geographical distance of over 9000 kilometres and a six-hour time difference, the motion data was transmitted in real time, thus enabling virtual interaction.

Based on Plato’s cave parable, the ZHdK performance “The Hidden Formula” explored mechanisms of suppression and restriction as well as the human will to be free. The piece was made in close dialogue with “The Heavenly Palace” by Zuni Icosahedron, which refers to the 16th century Chinese novel A Journey to the West.
The live performance of “The Hidden Formula” took place on 25 October at the ZHdK in Zurich and simultaneously at the Community Center in Hong Kong and was broadcast live in Zurich’s Bahnhofshalle as part of the Swiss Digital Day.

For data transmission, the TwinLab project relied on the findings and technological developments of the SNF research project “Telematic Performance”, which is housed at the Institute for Computer Music and Sound Technology (ICST), ZHdK.
