HCIL-91-13

This video explores the application of direct manipulation to information exploration. Specifically, it introduces the idea of a dynamic query, which empowers the user to search a database of information in the task domain while requiring minimal syntax or computer knowledge. Key features that separate a dynamic query from current information retreival systems are its direct manipulative nature, providing immediate search feedback with object interaction, and a harmonious display of the query and resul ts in a graphical environment appropriate for the task domain. Two different applications of dynamic queries are demonstrated: an education tool to explore the periodic table of elements and a hands-on system to help prospective home buyers find a home.
