An introduction to the Human-Computer Interaction Laboratory, also demonstrating a revised version of the FilmFinder, a visual information seeking environment for browsing films.
IVEE (Information Visualization & Exploration Environment) is a generic tool for the automatic creation of dynamic query applications. In our work for the Maryland Department of Juvenile Services, we use IVEE to explore a dataset of approximately 5000 juvenile case referrals. We demonstrate how IVEE can be used to find errors, compare workloads, and reason about display patterns. [ProjectDescription]
In our project for the Maryland Department of Juvenile Services we are developing new techniques to visualize youth records. By showing multiple time lines with selectable markers to retrieve detailed information, overviews are always available even for complex records. Zooming and filtering are possible and linked events can be highlighted. We show how this technique can be used to visualize medical patient record and personal histories. [Project Description]
The PDQ (for Pruning with Dynamic Queries) Tree-browser presents trees in two tightly-coupled node-link views: a detailed view and an overview. Users can use dynamic queries to filter nodes at each level of the tree. The dynamic query panels are user-customizable, i.e. users can select what node attributes to query on. Subtrees of unselected nodes are pruned out, leading to compact views of relevant nodes after a series of iterative refinements.
The National Library of Medicine is preparing an archive consisting of anatomical images of a male and a female subject, including MRI, CT and cryosection images. This collection of images will be available to a large community of users with varying backgrounds and expertise. We are exploring visual metaphors for browsing and querying anatomy databases. Our first prototypes include novel overview techniques for rapid exploration of volumetric data, and for browsing medical concepts and anatomical terms.[Project Description]
Careful design of the hypermedia documents used on the World Wide Web (WWW) is necessary for building an effective WWW site. Using the mixed media holdings of a small library as an example, several design guidelines, aimed at making a site more efficient for the user in the navigation / retrieval process, are presented.
We demonstrate a network monitoring prototype dealing with both physical network alarms (e.g. a node is down) and alarms generated by sensors installed in the business applications running on the network (inventory too low or too high, excessive number of orders, etc.). Our Enterprise Monitoring prototype provides tightly coupled filtered views of the networks current status and past history, timelines of alarm overviews and traditional textual details. Filtering attributes are modified interactively to deal with temporary needs or alarm overflows. [Project Description]
Interpretation of specifications is a difficult and error prone task. If a specification method is executable and graphical, the specification can be animated while the system is executed. Interaction Object Graphs (IOGs) are an executable, graphical specification method. IOGs are designed to specify user-interface widgets. This video explains IOGs and demonstrates their animation while the user operates the specified widget. Animation of graphical specifications has the potential to enhance specification utility by enhancing both debugging and communication.
WinSurfer is a directory maintenance tool running in MS Windows and using treemaps. Treemaps are a novel method for displaying hierarchical information using a 2-D space filling algorithm that partitions a rectangular region. WinSurfer lets you gracefully and rapidly examine your directory and invoke file actions.
