Marc<br /> <br /> == Short description ==<br /> Graphs with hundreds of vertices and edges are common in many application areas of computer science. Displaying all this information on a screen has the disadvantage of loosing the details. Alternatively, zooming into a part of the graph does show local details but loses the overall structure of the graph. Displaying two views – one view of the entire graph and one of a zoomed portion of it – has the advantage of seeing both local detail and global structure but the drawback of requiring extra screen space and forcing the viewer to mentally integrate the views.<br /> A fisheye view of a graph shows an area of interest quite large while the rest of the graph remains smaller and in less detail. The viewer can position the mouse to the area of interest of the graph and determine the focus point in that way. As the mouse is dragged, the focus changes and the display is updated smoothly in real time.<br /> The appearance of the fisheye view can be varied by changing the distortion factor of the lens. With the distance from the focus and a number, which is assigned to each vertex to represent its relative importance (a priori importance (API)) in the global structure, the visual worth for each vertex is computed.

<p>UE-InfoVis06-12: </p> <hr /> <div>[[Image:GutwinCarl.jpg]]<br /> <br /> '''Carl Gutwin''' is associate professor in the Department of Computer Science and the director of the Human Computer Interaction (HCI) lab at the ''University of Saskatchewan (Canada)''.<br /> <br /> His main research areas are Computer-Supported Cooperative Work, Information Visualization, and Information<br /> Retrieval. In particular, he's interested in ways that groupware systems can better support the fluid and natural interaction that is evident in face-to-face collaboration. In a recent project, he used the idea of workspace awareness - knowledge of where people are and what they are doing in a shared workspace - to improve the usability of a groupware application.<br /> <br /> [[Category:Persons]]<br /> == Publications ==<br /> <br /> A list of the publications of Carl Gutwin can be found here:<br /> *http://pirandello.usask.ca/publications/index.xml<br /> <br /> <br /> == External links ==<br /> <br /> *http://www.cs.usask.ca/faculty/gutwin/</div>
