We now communiate on the web using webcams and youtubes. Imagine three or ten people from different locations are collaborating with each other. How can one aware the others' spatial location and social background? How can we understand their activities as a whole? Isn't it interesting to integrate geographic and a wide variety of context information with the video? Look at the prototype we created. It'll appear in IEEE Visualization Conference 2007.(http://vis.computer.org/vis2007/)
