I propose to design and evaluate a hierarchical category browser interface for children. Previous tools for handling hierarchical data rely on text-based visualizations, lose or distort global context, and/or rely on complex abstractions, excluding children from using them. I will instead use graphic representations of hierarchical categories and animated query creation in an accessible, web-based environment to support conjunctive queries. I will evaluate this tool using iterative design and a study comparing it with a version without animated query creation.
