Study on event-related potential of information alarm in monitoring interface

Abstract

Conduct research on the problems caused by the improper design of alarm modes in the digital interface of monitoring system. Based on the behavior data and physiological data obtained by the event-related potential brain electrical experiment, compare the influences of the two alarm modes of interface elements size change and color change on the visual cognition of users, analyze the key elements that cause these reasons and lay the foundation for the improvement of alarm modes of monitoring interface. In the brain electrical components of color change and size change, N100, P200 and P300 are more obvious, and they are focused on the top region, the central left top region and the central right top region. As for the present of digital interface alarm information, in the present method with the same channel, participants is more sensitive to the color code change, although the activation degree of size change on human brain is higher. The data analysis and conclusion of this thesis can provide reference for the design of the digital interface alarm mode in the future, so as to effectively avoid the users’ misjudgment and omission on the interface information and improve the use efficiency of system in reality.
