With a novel VR-based modeling tool virtual nerve cords are inserted into these anatomical
data sets. Functional anatomical systems are used to manage these data sets and provide an
interface for simulation algorithms. The most essential part of the simulation is the electric
impulse transmission through inhomogeneous soft tissue, which results in nerve stimulation
and motor response (i.e., muscle activation). In order to achieve this, path finding algorithms
have been adapted and rules of electrophysiology are employed.
Real-time Room-Acoustics for interactive and dynamic Virtual Environments
D. Rausch, T. Kuhlen
This project is a joint-research project with the Institute of Technical Acoustics (Prof. M.
Vorländer, and D. Schröder). It is funded by the German Research Foundation (DFG). The
focus of the project is the implementation of an immersive virtual environment with a
dynamic and real-time capable acoustic reproduction. The main features are the capability to
change the room-acoustic simulation parameters inside of a virtual environment. Thereby the
acoustic simulation accounts for advanced effects such as diffraction, transmission and
scattering in dynamic environments. The overall system is to enable novel applications, for
example interior architecture or training of emergency situations.
Subtasks of the project are the evaluation of the degree of immersion into a virtual scene by
the help of highly plausible auralizations in conjunction to the visual environment. The
system is based on developments of a preceding project also supported by the DFG where the
acoustic reproduction of dynamic spatialized sound sources with few loudspeakers was in
focus. Main work packages research on the ability for advanced manoeuvring in the virtual
environment with the help of acoustic stimuli, the real-time visualization of the acoustic
simulation inside of a virtual sound laboratory as well as the parallelization of the simulation
algorithms in order to enable real-time processing of the room acoustics simulation. Other
aspects cover the development of novel interaction technology for the modification of the
dynamic room setup.
VATSS - Virtual Air Traffic System Simulation
A. von Kapri, S. Pick, T. Kuhlen
In this work, which has originally been funded by the Interdisciplinary Pathfinder Projects
Initiative and which since recently converted into a Boost Fund Project, we collaborate with
the Institute of Aeronautics and Astronautics (ILR) and other RWTH working groups on the
development of a concept for an interdisciplinary simulation of the air traffic. The simulation
of different aspects of an air traffic system will be combined with a three-dimensional
visualization in the virtual environment of the CAVE.
