Research on the Brain Mechanism of Visual-Audio Interface Channel Modes Affecting User Cognition

In multi-channel design, the combination of visual-audio dual channels is the most widely used way. This article elaborated on the characteristics of visual and audio channel, clarified the complementary relationship between visual and audio channels, and analysed the combination methods of visual and audio channels. EEG/ERP technology was used to carry out experiments and some alarm information designs of a real-time monitoring software system were used as an example to compare the cognitive differences caused by the combination of visual and audio channels’ combination. Through the quantitative analysis of indicators such as reaction time, brain wave peak value, and latency, the interface information design and evaluation methods for visual-audio dual channels were developed.
