This study focused on how assistive technologies (ATs) affect the ability-disability construct of adult-onset locomotor disabled individuals in the South African city of Johannesburg. Its main aim was to understand the socialized use of assistive technologies in adult-onset locomotor disabilities and to unravel how the socialized use of assistive technologies affect the users’ interpretations of the ability-disability construct; through the perceptions of the participants within a developing world context. Relatively, there have been few ATs studies in South Africa and they have excluded the ‘voice ‘of the disabled people. Ten conveniently sampled adult-onset locomotor disabled individuals participated. An interpretive technique in the form of semi structured one hour interviews was used for data collection. The descriptors of events for the thematic analysis were the patterns or themes in which participants were constructing the narratives of their lives. These patterns were formulated using Braun and Clarke (2006) six stages of identifying, analysing and reporting patterns within the data. Transcribed texts from the ten semi-structured interviews were subjected to thematic analysis based on how the participants perceived their assistive technologies. Four central themes emerged which centred on how people perceived their ability-disability; the social acceptability of ATs, accessibility factors and new trends in assistive technologies. The research findings indicate that most adult onset disabled individuals in a South African context tended to embrace the promises of technology centred on positive attributes such as: improved communication with others, increased mobility, physical safety, personal autonomy, control over one's body and life, independence, competence, confidence, the ability to engage in the workforce and participation in the wider community. Although such positive attributes seemed to reinforce perceived ability as the boundary between disabled bodies, technology was blurred. However, this perceived ability was found to be rather misleading since it was premised in the same medical and social discourse that ‘disabled’ individuals. T he participants’ narratives were constantly constructing and reconstructing the way they perceived themselves as able or disabled. The studies therefore recommend that, disability narratives on the perception of ATs should be viewed as fluid, complex and multi-layered.

In 1992, the Web was invented by Tim Berners-Lee and Robert Cailliau at the European Laboratory for Particle Physics (CERN) as an application over the Internet using TCP/IP protocol as stated in the World Wide Web Consortium (WC3). Accessing local IS to process data is no longer appropriate in the revolution of distributed processing. Web environments are heterogeneous and portable. First, the Web was developed for textual publishing purposes. However, in parallel the rapid advances of related technology and the incredible growth of ubiquitous data, the Web has evolved from a static medium for information sharing into an interactive multimedia platform that includes video, sound, animation, with dynamic links. In the light of these advancements, Web accessibility and associated problems (eg. People with deafness), represent a serious obstacle that prohibits people with special needs from accessing telecommunication systems. The Deaf Community’ is almost a closed community that has its own language (i.e. sign language), customs and traditions. There is little research around the world investigating direct machine translation of sign language. To avoid machine translation and associated problems, this thesis built on current Web technology to integrate Signage Information into the Web environment. As part of this integration, it made use of an ‘Intermediary Signage Object’ rather than intermediate transmission of video-based sign language. Finally, this thesis provides a Sign Language Annotation tool. It generates an XML document in order to process signage object content. The Graphical Usage Interface (GUI) contains a display window that plays customized sign language clips according to the sign viewers’ preferences. The Signage Tool extends IBM VideoAnnEx Tool to include sign language attributes and related data. In addition, it has been developed for different types of users involved with the deaf community (i.e. hearing impairment, hard of hearing, and sign language interpreters.) / Master of Science (Hons.)

Our research posits a context-sensitive, adaptable, assistive services and technology system (CAAST) that takes advantage of the advancements in mobile computing to provide barrier-free access to environmental information and devices. To inform our research we explore the following topics: the deficiencies associated with current assistive technologies; the advances in wireless sensor node technology; the interference and accuracy problems associated with wireless location detection; the coordination problems associated with service discovery; the management and coordination problems associated with decentralized sensor nodes; the separation of information and activities from the human interface; the efficiency and abstraction problems associated with interface description languages; and the adaptation of information and activities to meet the needs of those with disabilities. As a result of our research into these areas we devise an assistive technology, CAAST, that intends to be a comprehensive approach to universal access to information and activities for those with disabilities. / Department of Computer Science
