Virtual reality and its implementation in transport ergonomics

The experience of our environment is based on the information that reach us by means of our sensory organs, and which are subsequently processed in our brains. Digital interpretation implemented to mathematical models of the studied subjects brings us to the so-called virtual reality that allows us to replace some natural human senses, in this case the visual ones, by computer-generated information. The procedure is expanded to three-dimensional (3D) scanning i.e. searching of the special form of the observed subject/object, then digital recording of the space point cloud (pixels) which correspond to the item, then vectorisation of the form, rendering and finally animation. In this way, by watching the display, the impression of the virtual environment can be generated in the human perception. Moreover, in this way the human model can be realized in a characteristic way in such a virtual space. The implementation of this virtual reality, in accordance with the possibilities that it provides, has been the subject of very intensive research in the world, and in Croatia as well. The work presents some possibilities of applying virtual reality in the field of ergonomic analysis of the collision process of two vehicles.
