Providing Access to Graphical User Interfaces: The Mercator Project

摘要

The purpose of this work was to enhance the existing Mercator research prototype to a commercial software system. The goal was to develop a commercial screen reader software system running on the Sun platform called UltraSonix. UltraSonix provides transparent access to X applications based on the Motif toolkit. Motif is the most common toolkit for building X applications; over 90 percent of X applications are built using Motif. UltraSonix allows transparent access of "off-the-shelf" Motif applications by blind users; no modifications to the applications are necessary to allow access.
