Resumo


This dissertation investigates the use of Virtual Reality for the exploration of multidimensional data represented as 3D scatterplots. After an initial user study indicated that an immersive environment required less effort to find information and less navigation, but resulted in inefficient times and frequent user discomfort, we proposed and evaluated an alternative data exploration approach based on the use of physical movements, direct interaction with data at arms reach and a virtual reproduction of the analysts work desk. Through a second study, we demonstrate that this setup, named VirtualDesk, presents excellent results regarding user comfort, and performs equally or better in all tasks, while adding minimal or no time overhead and amplifying data exploration.
