Virtual 3D design of work place with operating computers

The goal of investigation in this work was to perform a scientific 3D visualisation of work place and operator operating three computers. By inverse-kinematic, computer-based visualisation of a virtual 3D character in interaction with a digitized, really designed computer and environment the dimensions of operative elements in the process of operating the computer were determined. In addition, a biomechanical analysis of movements was carried out and dynamic anthropometric measures where calculated. By a 3D anthropometric analysis of movements the values of movement angles and the spine rotation of the worker, who is 170cm, 180cm and 190cm high in a sitting working position, were calculated. The results show that the movements of the spine as well as angles of the rotation of shoulders and elbows of all three operators are different and depend on their height. The operator moves when working so that the ratio between the body segments of the upper body part changes dynamically and the lower part is more static. The purpose is to keep biomechanical, more regular movements by applying skill. By better designing a work place and technical appliances energy consumption and operator fatigue would be reduced.
