1:15:08  Mandy's Question   


The catch phrase these days is ‘big data’ and this phrase is often accompanied by the assumption that it is matched with big industry and big science. However, as individuals we are becoming more aware that data is also impinging on our personal lives.

Since my overarching research goal has long been to design, develop, and evaluate interactive visualizations so that they support our everyday practices as we view, represent, manage, and interact with information, I am interested in this impact.

I still think that interaction is the key to exploration and manipulation capabilities that can make information comprehension viable. In this talk, I will start by showing examples of how a humancentered approach can improve visualization outcomes and then discuss how the currently shifting information climate is opening up new research opportunities, notably in personal visualization and visualization literacy.

I will discuss the interplay between small data and big data considering the potential for empowering ourselves in our everyday lives.
