However, previous research has shown that individual differences do matter when presenting visual content. Our experimental results demonstrate the ability to determine a user's extraversion in real time by analyzing their interactions with a data visualization found on many platforms, the node-link diagram. The results show that users with higher extraversion moused-over more nodes than those with lower extraversion, showing a distinct difference in behavior between user trait groups. I then discuss the results of the experiment, and the impact this finding has for user trait modeling.; Thesis (M.S.)--Tufts University, 2018.; Submitted to the Dept. of Computer Science.; Advisor: Remco Chang.; Committee: Remco Chang, Megan Monroe, and Zahar Prasov.; Keyword: Computer science. %[ 2022-10-12 %9 Text %~ Tufts Digital Library %W Institution
