Project aim is to develope a versatile training platform for safety eduation of personnel with the primary use in the construction industry. The training environment framework ensures the possibility that after certain adaptions the platform could be used in other sectors of economy. In order to provide such opportunities, it is necessary to create an easy to use VR training environment. The choice of technology is based on analysis of benefits and limits by application of different technologies (e.g., synthetic VR environment, replica or digital twin, specially adapted physical environment with a calibrated VR environment). The technology is available for commercialisation.
