Exploring gesture based interaction and visualizations for supporting collaboration

Abstract: This thesis will introduce the concept of collaboratively using freehand gestures to interact with visualizations. It could be problematic to work with data and visualizations together with others in the traditional desktop setting because of the limited screen size and a single user input device. Therefore this thesis suggests a solution by integrating computer vision and gestures with interactive visualizations. This integration resulted in a prototype where multiple users can interact with the same visualizations simultaneously. The prototype was evaluated and tested on ten potential users. The results from the tests show that using gestures have potential to support collaboration while working with interactive visualizations. It also shows what components are needed in order to enable gestural interaction with visualizations.
