Information search in interactive information visualization

Abstract This study explored the effectiveness of outbreak data dashboards in presenting relevant information during global health emergencies using mouse-tracking measures. Firstly, several problems in the visual design and information layout of the dashboard were identified by analyzing the path, mouse-movements and clicks made by users when using the dashboard. Secondly, suggestions on the process of how dashboards were used and their design were collected through user feedback and follow-up interviews during the experimental process. The results of the study provide insights into user-centered design solutions for visual dashboards, which can guide the design of similar epidemiological dashboards in the future.
