TY - JOUR T1 - Browsing Unix Directories With Dynamic Queries: An Evaluation of Three Information Display Techniques JF - Technical Reports of the Computer Science Department Y1 - 1998 A1 - Liao,Holmes A1 - Osada,Masakazu A1 - Shneiderman, Ben KW - Technical Report AB - We designed, implemented, and evaluated an innovative concept fordynamic queries which involves the direct manipulation of small databases. Our domain was directories in a Unix file system. Dynamic queries allow users to formulate queries and explore the databases with graphical widgets, such as sliders and buttons, without requiring them to have any knowledge about the underlying structure of the database query languages, or command language syntax. Three interfaces for presenting directories were developed and tested with eighteen subjects in a within-subject design. The results of the formative evaluation yielded some useful guidelines for software designers. (Also cross-referenced as CAR-TR-605) UR - http://drum.lib.umd.edu/handle/1903/379 ER -
