Abstract: The present work proposes the use of information visualization techniques allied to an Augmented Reality user interface to provide information that helps professionals to analyze spatially situated data where it was originally measured. This problem and the proposed solution may be adapted into different professional contexts. Three visualization use cases were designed, implemented and tested in different task contexts, namely classroom seat analysis, GPS route following and EMC data-extraction. Apart from visualizing the situated data, users were also able to interact with it to narrow down their search by switching the attributes being displayed, combining them together, applying filters, changing its formatting and extracting values from it. The proposed approaches were tested against each other in comparable 2D and 3D interactive visualizations of the same data in a series of usability and performance assessments with users to validate the solutions. The goal was to ultimately expose how AR can help users to perform better in different decision-making contexts. Our results exposed significant effects on many of the variables measured, such as accuracy, correctness, distance traveled and time taken.
