LensBar-visualization for browsing and filtering large lists of data

The author proposes a simple and powerful graphical interface tool called the LensBar for filtering and visualizing large lists of data. Browsing and querying are the most important tasks in retrieving information and LensBar integrates the two techniques into a simple scroll window with slider. While it looks familiar to users of conventional graphical interface tools, its filtering and zooming features offer sophisticated handling of large lists of textual data.
