Paper Abstract

We have developed methodologies to study the usability of documents. This methodology has been applied to the study of the impact of visible security patterns in the usability of typical office documents. Two specific information retrieval tasks have been examined - the retrieval of text-based information from a written report and the retrieval of numerical information from tables and graphs. The methodology we have developed aims to minimize sources of uncontrolled variability in the measurements while simultaneously avoiding a systematic bias from learning effects and maintaining task equivalence across all documents. We believe the methodologies developed in this work may prove useful in future studies of document usability.
