FRAVE: Flexible virtual reality system

01.06.2011
Mobile virtual world

Product designers harness time-consuming procedures in prototype construction. Only then are they able to assess the results of their work in a comprehensive manner. In a three-dimensional model world, they are able to do so instantly and can experience how the product fits into its natural surroundings. Design alterations can be visualized immediately, saving time and cutting the costs associated with the development process.

Up to now, the so-called CAVE has been used. This consists of between three and six projection surfaces that create a walk-in space. Video projectors are used to visualize the calculations and applications in real time and in 3D. The nearly-closed space allows for intense immersion in virtual reality.

The FRAVE also offers this degree of so-called immersion. However, it is capable of even more: it can be used in a variety of ways thanks to its flexible, modular structure. "An engineer wants to enter the 3D world to be able to envisage the interior design of a vehicle. A researcher wants to visualize his or her measurement or simulation data, while a manager uses it as a presentation space," as Dr. Marcus Tönnis, scientist at the TU München Faculty of Informatics explains.

The FRAVE is made up of ten plasma screens with a screen diagonal of 65 inch which can be arranged in different ways. When they form a floor and an enclosure on three sides, the user is immersed deep in a virtual explorative world. The screens at the sides can be opened wide, with a tracking system on the screens automatically adapting the image display to the movement of the side sections. The side sections can even be disconnected from the system entirely. "In a meeting, I can simply push the screens up to the table to demonstrate a 3D view. In this way, the system comes to users and not the other way round," says Tönnis.

As the FRAVE consists of end user devices, it is significantly less expensive than the CAVE, an advantage that could promote more widespread use of Virtual Reality Systems. Another important benefit of the FRAVE is its a smaller footprint. Since the CAVE normally uses back projection, a lot of room is needed behind the projection surfaces. It requires at least 8 x 8 x 8 meters, while a space of 3 x 3 x 3 meters is sufficient for the FRAVE, thereby facilitating installation and relocation.

Researchers at the TUM Faculty of Informatics use the FRAVE to view simulation data. For example, the landscape of Saudi Arabia is displayed virtually as part of a project being run in collaboration with the King Abdullah University of Science and Technology (KAUST). Unlike existing virtual globes, like Google Earth, this system is able to show images above and below the earth's surface. As part of another joint research project, the FRAVE is being used to simulate CO2 separation and storage processes in order to optimize crude oil extraction.

Im Focus: A Challenging European Research Project to Develop New Tiny Microscopes

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.

To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
