Analysis and Modeling of the Negative Impact of Virtual Reality

During the use of virtual training complexes for the training of specialists in the engineering, chemical, mining industries, in the course of numerous studies, the negative impact of virtual reality on the physical state of a person is noted. These include various types of motion sickness, dizziness, nausea, disorientation in space. Therefore, an actual task is researching of causes and the degree of influence of negative factors using virtual reality technologies. To track negative effects, an algorithm for analyzing user's state has been developed, which allows collect data of person's state during the interacting with virtual reality. The algorithm allows fixing quantitative and qualitative metrics. Calculation of metrics is formalized in a mathematical model of process of the virtual reality influence on a person. Algorithm and model are tested on example of an exercise on moving simple virtual objects, data is obtained on a focus group of young specialists. Dynamics of changing quantitative and qualitative metrics is evaluated; it received an idea of degree of influence of negative effects on studying process.
