Faster performance means better understanding? User’s Performance and Attitude versus Understanding of Data in Interactive Information Visualization
Interactive information visualization (InfoVis) has become very popular and commonly seen in our everyday life. Studies on interaction in InfoVis have also been extended in many aspects: new interaction techniques, design principles and evaluation. However, very few researches mentioned people’s understanding of data in their interaction evaluation. This paper aims at confirming some typical evaluation measurements, namely task performance time and subjective attitude, and their relationship with the understanding of the visualized data.
We conducted an experiment involving two different interaction techniques (WIMP and non-WIMP) on a same InfoVis case with the same task. Through the experiment, people’s understanding of data, together with task performance time and subjective attitude were measured. The collected data showed a significant correlation in the WIMP interaction condition, where task performance time is positively correlated to the understanding of data. But since our results did not display any correlation between variables elsewhere, we suggest that it is better for future studies on interaction in InfoVis to include understanding of data as one of the evaluation measures.
