This project continues the HCIL attack of the problem of browsing and retrieving information from very large databases. This work explores the use of tools such as dynamic queries and techniques for two-phase query formulation which allow the searcher to get a useful view of the overall scope and size of the potentially relevant data sets before plunging into highly specific queries. The National Library of Medicine Visible Human Project supported Chris North's work presented in The Visible Human Explorer . The Visible Human Explorer is a browser which contains 1880 male cross-sectional images, taken at every 1mm. A coronal-section image was digitally reconstructed directly from the Visible Human cross sections.
Users can download single images or ranges of images as needed.
Using various sliders users can explore a digital reconstruction of human anatomy. Other suggested uses for slider technology included browsing digital video, thereby allowing exploration of motion trends in video. Extending beyond this there is the potential for working with any type of sequential data patterns. Evaluation Tools Victor Basili of the Department of Computer Science chaired the third session of the day. This section of presentations focused on the tools used to evaluate both user interfaces and user satisfaction with the interfaces.
