SignSupport: A mobile app for the Deaf Community

Almost one million South Africans who are Deaf use South African Sign Language (SASL) as their primary means of communication, as many are unable to speak, read, or lip-read in any of the eleven official spoken or written languages. This diverse, multi-ethnic community is largely excluded from communication with the hearing majority. As a result, government services and public information — including healthcare — which are primarily delivered in the official languages, remain inaccessible to much of the Deaf community.

SignSupport is a mobile application designed to bridge this communication divide. It unlocks pre-recorded SASL videos stored on a mobile device, enabling Deaf and hearing people to exchange information in their preferred language. The app supports interaction with non-Deaf users in specific, limited communication contexts — such as pharmacy consultations and International Computer Driving Licence (ICDL) training.

The prototype has since been refined and adapted for use via a WhatsApp interface and further developed for diabetes self-management within the Deaf community. When pre-recorded content or limited interaction is insufficient, users can initiate a video call with a remote SASL interpreter for additional assistance.

Although the primary users of this technology are members of the Deaf community, the Department of Health and private healthcare providers may also find it valuable for delivering self-care guidance and other health-related information — and it can be readily adapted for such purposes.
