Virtual Reality and its Implementation in Transport Ergonomics

The experience of our environment is based on the informationthat reach us by means of our sensory organs, andwhich are subsequently processed in our brains. Digital interpretationimplemented to mathematical models of the studiedsubjects brings us to the so-called virtual reality that allows us toreplace some natural human senses, in this case the visualones, by computer-generated infonnation. The procedure is expandedto three-dimensional (3D) scanning i. e. searching ofthe special form of the obse1ved subject/object, then digital recordingof the space point cloud (pixels) which correspond tothe item, then vectorisation of the fonn, rendering and finallyanimation. In this way, by watching the display, the impressionof the virtual environment can be generated in the human perception.Moreover, in this way the human model can be realizedin a characteristic way in such a virtual space. The implementationof this virtual reality, in accordance with the possibilitiesthat it provides, has been the subject of very intensive researchin the world, and in Croatia as well. The work presentssome possibilities of applying virtual reality in the field of ergonomicanalysis of the collision process of two vehicles.
