NoViSim is a "driver-in-loop" system, meaning that the driver's inputs to the vehicle are monitored and used to calculate the vehicle parameters as it is "driven". Those parameters include, but are not limited to typical performance predictions values such as RPM, speed, load and crank angle. This values in turn are input to the sound, vibration and visual simulation modules. Each of those modules in real-time updates and synthesis the actual displays and outputs for sound, vibration and visual. The simulator currently includes a set of 5 separate modules for evaluations:
1.) Non-Interactive Jury Evaluation
2.) Quasi-Interactive Jury Evaluation
3.) Fully Interactive Evaluation
4.) Fully Interactive Evaluation, with compnent switching
5.) Fully Interactive Evaluation, with in-line filtering.

This modules enable the user - while driving the simulator car - to
- evaluate and rate sounds and vibration
- switch between different sound and vibration sets respresenting different cars on the fly
- switch individual components of one car on the fly (e.g switch between different exhaustion pipes
- on the fly apply filters to sound sets and components

NoViSim features a family of simulators which all share a common core technology, but differ in the type of car interface used and in the availabilty of advanced modules:
- desktop simulator
- mock-up simulator
- static vehicle simulator

The desktop simulator uses a gaming pad for driver input and does not require more than 1-2 PCs for operation. This solution is ideally suited for the engineers workplace. Using the desktop simulator the engineer can immediately test and evaluate the output from the NVH engineering process. While the desktop simulator mainly focusses on interactive engineering and pre-selection as well as preparation of evaluation experiments, the more advanced versions of the simulator enable you to run the experiments under increasingly realistic conditions, a crucial factor in making final decisions in the NVH design and engineering process.
