This paper presents a description of telecommunications for Deaf people in South Africa by contrasting the situation in the developed world. We explain the main motivations for providing a locally appropriate solution. Research activity began with a community-based field trial of TTYs. The recommendations of the trial motivated an innovative approach to… (More)
In tightly circumscribed communication situations, an interactive system resident on a mobile device can assist Deaf people with their communication and information needs. The Deaf users considered here use South African Sign Language and information is conveyed by a collection of pre-recorded video clips and images. The system was designed and implemented… (More)
When undertaking a project in community-based co-design, students and their teachers must embrace uncertainty.
The computing for development community knows how to build user interfaces using qualitative methods for text illiterate users, especially on mobile devices. However, little work has been done specifically targeting Deaf users in developing regions who cannot access voice or text. This paper describes a multi-disciplinary collaboration towards iterative… (More)
Introduction The majority of the Deaf community in South Africa is marginalized from First World telecommunication solutions by a variety of factors. Fortunately, these detrimental factors provide opportunities to advance research methodology and technical solutions for Deaf Telephony. Without human-mediated telephonic relay between Deaf and hearing users… (More)
BACKGROUND Many cultural and linguistic Deaf people in South Africa face disparity when accessing health information because of social and language barriers. The number of certified South African Sign Language interpreters (SASLIs) is also insufficient to meet the demand of the Deaf population in the country.

This paper discusses a prototype of a learning aid on a mobile phone to support Deaf people learning computer literacy skills. The aim is to allow Deaf people to learn at their own pace which in turn reduces the dependence on a teacher to allow weaker learners be assisted. We studied the classroom dynamics and teaching methods to extract how lesson content… (More)
Recognition (ASR) utilities accessed via web services. To perform Action Research with the Deaf community in Cape Town, we invited a Deaf user (DU) to participate in a pilot study. We conducted three tests varying the input/output modalities of the hearing user (HU). The DU had a standard text in/text out Instant Messaging client. The HU client used the… (More)
