Evaluation of Information Visualization Interaction Techniques Using Gestures and Widgets in 3D Environments

This paper presents the results of usability evaluation of an Information Visualization tool with touchless gestural commands. The tool has well-known visualizations tasks implemented in itself, allowing users to interact on a 3D scatterplot visualization technique. The chosen usability evaluation was the Think Aloud protocol, together with questionnaires conducted by an interviewer, both of them performed with five participants in a controlled environment.
