One Framework of Automation Design Based on Operator Cognitive State Assessment

Abstract

The rapid developments of technology and science have made automation broadly applied in all aspects of human- machine systems. In reality automation does not merely supplant but changes human activities, and can impose new coordination demands on human operators. For the whole system security and reliability, proper design of automation systems is very essential. Based on a thorough analysis of automation effects on human- machine systems, especially on human operators, this paper presents one feasible framework of automation design guided by human-centered automation, with the expectation to prompt the design of human-machine systems and the cooperation between human and machine, especially automation systems, and further to enhance whole system security and reliability. Moreover, the analysis results may be of great benefit to the task allocation of human-machine interaction and the design of automation support systems in emergency situations. In reality, the function modes of the automation systems are mainly determined by their design. Based on a thorough analysis of automation effects on human-machine system, especially on human operators, this paper presents one feasible framework of automation design guided by human-centered automation, with the expectation to prompt the design of whole human-machine system and cooperation of human and machine, especially automation systems, and further to enhance whole system security and reliability. And this paper is organized as following. Firstly, automation effects on human-machine system, especially human operators, are explored in detail. Secondly, combined with human cognitive state assessment, one feasible framework of automation design in human-machine systems is presented, and its function mechanism is illustrated. Lastly, conclusions and recommends are given for the future research.
