In 2005, DDO designed a sophisticated photo tagging and search interface for a consumer photography product. Our design included advanced concepts like hierarchical tags and Boolean operators, but still enabled users to tag and search their photos in intuitive ways. Users can search by entering text, clicking tag buttons, or a combination of both.

The top image shows a search operation via dragging tags into the search field—a revolutionary idea—in addition to traditional text entry, creating a simple Boolean operation. The image below shows the filtered results.
