The influence of external cognitive load on the perception of information in the interface

The article considers the influence of external auditory cognitive load on the perception of visual information in the interface. The relevance of the topic is due to the need to improve the reliability of human-machine interaction in critical areas such as aviation. In an experiment involving 74 undergraduates using i-tracking, parameters of visual behavior were assessed during the performance of a visual task with parallel listening to text. It was found that cognitive load increased the time spent looking at elements when they were laterally arranged. The use of icons in the interface reduced the impact of load compared to text. The results emphasize the importance of interface structure for distraction tolerance and demonstrate the potential of i-tracking as a tool for assessing cognitive load.
