Metaphors for Nonvisual Computing

Abstract

Many of the systems in this book exemplify negotiating a technological barrier in order to provide access to a computer or other device. The necessity of providing access of any kind to existing devices has often outweighed the desire to design systems specifically for a small, although important, group of users. For example, computer access has been almost completely driven by the goal of overcoming more and more technological barriers. Currently, a significant problem in computer access is providing access to Graphical User Interfaces (GUIs) for computer users who are blind.
