Исследование соответствия информационных процессов и зрения специалистов в системах с высокой профессиональной информативной нагрузкой

Abstract

In our age of high speeds, the human body receives a very heavy load on the organs of vision, thereby increasing the likelihood of deterioration in their work. As a result, people lose their vision, they distinguish simple and complex objects worse, spend more time recognizing signs, symbols, letters that they previously saw and distinguished much faster and easier. For most professions, this circumstance is not critical, but there are a number of areas of human activity where the visual factor is of paramount importance. First of all, this applies to the work on monitoring equipment that dispatchers, operators and controllers are associated with. Working under constant visual stress requires a high motor activity of the oculomotor system, visual acuity and high cognitive abilities. Thus, an important task is to identify and constantly monitor visual reflexes of dispatchers operating in conditions of high visual and information load. There are many different methods and means that are aimed at determining the acuity of a person's vision. But most of them are presented in the form of paper diagrams and pictures, which does not allow for a comprehensive assessment of the state of visual acuity. Thus, the aim of the study is to develop a technology for analyzing the correspondence of information processes and the operation of the visual system among specialists with a high professional information load. To determine information components of the operator's work cycle, the information field was represented in the form of a matrix of elements in which each element is assigned its own weight, which determines the importance of the information process located at a given point in the operator's information field. To accurately determine visual acuity, a test object and a corresponding table for visometry were selected. A study of the conformity between information processes and vision of specialists in systems with a high professional information load was carried out using the developed specialized software. The developed software is based on scaling and measuring the response time to changes in the position of the diagnostic test object. The software allows you to store and edit data, perform their statistical analysis and sorting. The program has several research modes, namely determining the location of a small circle of the optotype and reducing it, as well as recording the response time of the subject to changes in the position and size of the optotype. Thus, we get an accurate picture of the space-time abilities of the visual system of the dispatcher in accordance with information processes in his professional activity. The developed specialized software is synchronized with the matrix of importance of information processes, allows monitoring the state of the visual system of specialists with a high professional information load and creating an information space that is the most optimal and adapted to the visual apparatus of dispatchers and operators. Experimental studies of the developed technique were carried out. The developed method will significantly reduce the risk of errors and inaccuracies in the work of dispatchers and operators, which is of significant importance for the country's economy, since any error can affect a huge number of people and production processes. In addition, the software allows you to keep statistics of data and indicators and enter them into a single information base, which will facilitate the examination in the future and provide an opportunity to track the dynamics of pathologies. The results obtained during the study can be widely used in various areas of production with a high information load.
