VISVIP: 3D visualization of paths through web sites

VISVIP allows web site developers and usability engineers to visualize the paths taken through the site by the subjects of usability experiments. They can dynamically customize and simplify the graphical layout of the web site, and select which subjects' paths to view. An animated representation of progress along the path through the web site is also available. The third dimension of the 3D display is used to represent the time spent on each page visit. The graph layout provided by VISVIP can be governed by either the web site topology or the intrinsic structure of the subject's path.
