THE STUDY OF ACCURACY OF AN OPERATOR’S PERCEPTION OF GEOMETRICAL OBJECT SIZES AND SHAPES IN THE VIRTUAL ENVIRONMENTS Ilya Tanryverdiev, Igor Petukhov, Luydmila Steshina, Ilya Steshin, Pavel Kurasov, Daniil Galkin Journal of Applied Engineering Science, 2024 This paper is devoted to the experimental comparison of accuracy of an operator's perception of geometrical object sizes and shapes between the different conditions of information perception in the virtual environments and from the electronic displays. The experiments were conducted using a psychophysiological test for the accuracy of perceiving geometrical object sizes and shapes by an operator in the virtual environments and in the conditions of information perception from an electronic display. As a common metric of the accuracy of perceiving geometrical object sizes and shapes, an operator was offered to visually determine the object center of gravity. No significant differences in the measurement results of both the accuracy of perceiving geometrical object sizes and shapes and speed of this process were found based on the different methods of displaying the visual information to an operator.
Research into the accuracy of complex sensorimotor responses of operators to joystick-run technological equipment Igor Petukhov, Luydmila Steshina, Ilya Tanryverdiev, Ilya Steshin, Pavel Kurasov, Danil Galkin 2024 25th International Arab Conference on Information Technology Acit 2024, 2024 This paper analyses the impact of visual information presentation methods on a human operator's control of remote technological objects, specifically focusing on the perception of information from electronic displays and the operator's immersion in a virtual environment, as it relates to the accuracy of joystick handle positioning. Experiments employed psychophysiological evaluations of accuracy and speed related to visual-motor tracking using joysticks. The findings revealed no discrepancies in the accuracy and speed of visual-motor tracking between groups participating in tests using information from electronic displays and those interacting with virtual environment. The paper provides recommendations on using virtual environments and displaying information on electronic screens for various operator tasks.
