Visualization, Interaction and Simulation Lab
Resumo
The Visualization, Interaction, and Simulation Laboratory (VISLab) at UFRGS is majorly concerned with data visualization and human-computer interaction research. Research on data visualization focuses on the development of information visualization techniques and their application to different domains. Studies on interaction emphasize non-conventional, 3D interaction and haptics in the context of virtual (VR) and augmented reality (AR) applications. We integrate these two areas into immersive analytics research and develop data visualization and novel interaction techniques based on VR and AR technologies. The main goal of our projects is to enhance the human with computers, extending the perception capabilities and improving the human power of action in a natural way. In this paper, we present our research focus and strategy to move towards that goal. We also briefly describe and illustrate some recent works developed in the lab.
