Abstract:

Just as it is important to choose the proper knife when slicing-n-dicing vegetables, it is critical to prescribe a suitable user interface to support faceted filtering. Faceted filtering allows you to narrow down a large list of objects to a manageable size by applying flexible combinations of attribute filters in any order. Rather than forcing you down fixed paths within a website’s information architecture, faceted filtering allows you to multi-dimensionally slice-n-dice the information in a manner that best accommodates your specific needs. A user interface that optimally supports faceted filtering must expose its robust functionality in a way that expresses affordances, controls complexity, and follows existing standards that have been pre-established across the web.
