Study on Error-Cognition Mechanism of Task Interface in Complex Information System

With the rapid development of computer technology and information control theory, information systems become more complex and intelligent. Transportation hub monitoring system, nuclear power control system, environmental monitoring system, and other large systems have evolved from the traditional control mode to digital control mode. Because digital information interaction interfaces are characterized by the large quantity of information and complicated information relationships, operators may enter the complex cognition and lead to task failures and even serious system failures or major accidents due to operators’ slipping, misreading, misjudgment, late feedback, and other cognitive difficulties. It is urgent to obtain the rational design way of dynamic and digital information in the interaction interface. This paper aims to analyze interaction mechanism between error and cognition and explore the physiological reaction mechanism for error factors of information interaction interface during the visual cognition from the perspective of the cause of task failures, error factors. The project results can provide theoretical supports for the rational design of digital information interface and guarantee the full performance and accurate implementation of large systems.
