Abstract
The paper investigates the usability of Virtual Reality (VR) for the evaluation of technical installations in areas of particular natural interest, which is extremely relevant for the authors’ region. The consideration of VR for evaluating the harmony of installations and the landscapes is due to impossibility to use physical prototypes to the scope. An unchanged container and three designs to disguise it aesthetically have been tested in a VR-supported experiment involving 12 volunteers. All of them were requested to evaluate the alternatives and their experience with VR by means of user experience questionnaires. The results show that the experience with VR does not affect the indication of preferences and it is therefore claimed that VR can be used beneficially in these circumstances.
