Abstract

 

One of the most serious problems dealing with car safety is a driver’s attention decrease and fatigue which could lead to the micro-sleep. For development of a warning system, which could detect driver’s inability to safe driving, it is necessary to have a complex knowledge about the processes inside driver’s body and mind. From that reason it is needed to perform plenty of experiments. Our laboratory investigates in actual driver’s state mainly using the means of brain activity measurements (EEG analysis) and other additional biological signals. All those measurements (mainly the brain waves) are very sensitive to environmental influences. On the other hand it is necessary to put the experimenting person into the environment which is as close to reality as possible. Using of car simulation devices appears to be a good compromise. Car simulators are very adaptive because of using virtual testing roads, which could be reconstructed for different type of measurement. The creation of virtual sceneries is a relatively time-demanding task because it requires all the objects to be separately modeled in 3D-modeler. From that reason we developed several tools which partially automate the building of virtual roads and surroundings. The paper gives a complex view on the subject of creation of virtual scene fitting to the needs of micro-sleep measurements using EEG analysis.
