Problem of operator activity in modern realities

Introduction. The article provides a theoretical review of the areas of study of the problem of operator activity as a special kind of professional activity of a person. Substantiation of the importance of the human factor in providing optimal operator activity, principles that underlie the creation of effective, convenient and intuitive technologies for interaction in human-machine systems, obstacles in operator activity and basic stages of processing of textual information in the system "operator". The purpose of the article is to highlight the problems of operator activity in the context of relationships in the system "man-machine" in the modern realities of today. Research methodology. Methods of theoretical analysis, comparison, comparison, systematization and generalization have been applied. Scientific novelty. The article states that the problem of improving the operator's professional activity should be solved in two main directions: first, it is a further successful design of technical means and equipment, taking into account the psychophysiological characteristics of the person and its adaptive capabilities; Secondly, it is the organization and implementation of individual professional selection, as well as the oriented training of operators, which should be adapted to the performance of specific types of work, even in conditions of complex and dangerous professional activity. Conclusions. It is substantiated that the problem of improving the operator's professional activity should be solved comprehensively and based on the principles that underlie the creation of effective, convenient and intuitive technologies for interaction in human-machine systems; It is proved that the issue of professional reliability of a person performing operator activity is very relevant in their medical and social significance, because a fundamental feature of any complex system "man-machine" is not only the technical involvement of an educated person, but also the need to take into account personal components; It is clarified that the study of the obstacles of the operator, is developed mainly on the basis of the study of the peculiarities of the perception of information sensory signals by the operator and, usually, are visual and auditory signals. The likelihood of unmistakable performance of psychomotor actions in the processing of visual and auditory signals is determined by the nature of existing obstacles that accompany the professional activity of the operator. The high obstacle resistance of the operator's memory to the effects of passive external obstacles indicates its adaptive capabilities, provided there are foreign sensory stimuli; Attention to the main stages of processing of text information in the system "operator-display" in the context of the implementation of psychomotor actions of the operator, namely: sensory memory, decoding of information signals in the neocortex, formation on the basis of analytical and synthetic activity of the brain of psychomotor action, psychomotor, psychomotor, psychomotor. acceptor the result of conscious actions, forecasting opportunities to improve the efficiency of professional activity; It is shown that taking into account the modern realities of uncertainty and turbulence of particular importance "human factor" in providing optimal operator activity, which involves the formation in the person-operator of stress resistance and adaptability to work in conditions of increased danger.
