Navigating the Graphical User Interface (GUI) by the Visually Impaired Computer User

摘要

The use of modern computers by the visually handicapped has become more difficult over the past few years. In earlier systems the user interface was a simple character based environment. In those systems, simple devices like screen readers, braille output and speech synthesizers were effective. Current systems now run Graphical User Interfaces (GUIs) which have rendered these simple aids almost useless. What has become an enabling technology for the sighted computer user is rapidly becoming a disabling technology for the visually impaired.
