In today’s heavily technology-dependent society, blind and visually impaired people are becoming increasingly disadvantaged in terms of access to media, information, electronic commerce, communications and social networks. Not only are computers becoming more widely used in general, but their dependence on visual output is increasing, extending the technology further out of reach for those without sight. For example, blindness was less of an obstacle for programmers when command-line interfaces were more commonplace, but with the introduction of Graphical User Interfaces (GUIs) for both development and ﬁnal applications, many blind programmers were made redundant (Alexander, 1998; Siegfried et al., 2004). Not only are images, video and animation heavily entrenched in today’s interfaces, but the visual layout of the interfaces themselves hold important information which is inaccessible to sightless users with existing accessibility technology.
