Description
The purpose of VISVIP is to visualize data generated by the WebVIP tool. WebVIP allows the UE to instrument a website so as to produce a log of activity when an experimental subject uses the site to accomplish some task. The log is essentially sequence of time-stamped URLs, indicating the user's path through the website.
Possible uses
- Help usability engineers cope with logging data from WebVIP - Apply 3D visualization to problem of understanding patterns of website usage.
Software characteristics
Handling
If a graph is highly interconnected, the UE can specify that the site be pictured as a tree emanating from a selected root node. VISVIP can also arrange the graph by treating pages as adjacent if they are connected by a userpath, rather than by the existence of a static link. The resulting display usually makes the structure of the path much simpler, albeit at the cost of complicating the display of the underlying website.
