Abstract: The classic search paradigm was used to study the impact of icon visual features and number changes on the cognitive performance of icon layout. Experiments showed when the number of icons was 6, only the main effect of icon visual features was significant, the icon layout had no significant effect on the search speed, and the icon visual features were the main influencing factor of cognitive performance; when the number of icons was 15, only the main effect of icon layout was significant, and the search speed of horizontal arrangement was the fastest. When the number of icons was more than 10, the reaction time of horizontal arrangement was significantly lower than that of vertical arrangement, and there was no significant difference in the error rate between them; with the decrease of L○ 长度/S宽度 ratio of graphic panel, the average reaction time difference between the two was gradually reduced and tended to be the same. Research showed that the number of icons has a significant impact on the cognitive performance of icon layout and visual features.
