In today?s fast-paced world, it's increasingly difficult to understand and act promptly upon the content from the many available information streams. Temporal pooling addresses this problem by producing a visual summary of recent stream content. This summary is often in motion to incorporate newly arrived content. This article reviews the perception of motion and change blindness, offering several guidelines for the use of motion in visualization. It then describes TextPool, a tool for visualizing live text streams such as newswires, blogs, and closed captioning. TextPool?s temporal pooling summarization is a dynamic textual collage that clusters related terms. TextPool was tested with the content of several RSS newswire feeds, streaming 800 stories per day. TextPool handled this bandwidth well, producing useful summarizations of stream content.
