Design and Effects of Personal Visualizations

In an effort to determine what elements need to be considered when designing personal visualizations, this research study explores how users react to different personal visualization designs. The authors present three distinct personal visualization designs (Timeline, Spark, and Bouquet) for visualizing Facebook user data. In a scenario-based user study, they interview participants to evaluation each design´s utility, exploring the visualization of the users´ own data, comparing two personal visualizations, and analyzing a series of personal visualizations. The analysis of the recorded conversations suggests that the illustrative design was the most well-balanced with respect to relaying information, motivating data exploration, and providing personal insights to the users. The authors believe this study will help guide future developers regarding the design of personal visualizations.
