    Mobile Communication Tools for a South African Deaf patient in a pharmacy context
    (IIMC International Information Management Corporation, 2012) Chininthorn, Prangnat; Glaser, Meryl; Freudenthal, Adinda; Tucker, William David
    This paper presents a case for iterative community-based co-design to facilitate the emergence of an innovative mobile system to address a potentially life-threatening scenario for Deaf people in South Africa. For Deaf people that communicate in South African Sign Language, miscommunication due to language barriers, under-education, under-employment and physiological deafness can lead to a potentially dangerous therapeutic outcome when Deaf people potentially misunderstand a pharmacist's instructions on how to take prescribed medicine. The design for a mobile communication aid to address this problem emerged from iterative cycles of action research performed with a local Deaf community that also involved pharmacists and a multi-disciplinary research team. Conventional user-centred design techniques were innovatively appropriated for the community-based co-design. The paper illustrates the community-based co-design process and points the way toward imminent implementation, as well as the potential application of the mobile solution to other scenarios in Deaf people's lives.

    Usability of an authoring tool for generalised scenario creation for signsupport
    (Telkom, 2015) Duma, Lindokuhle; Chininthorn, Prangnat; Glaser, Meryl; Tucker, William David
    This paper presents the usability testing results for an authoring tool that generalises scenario creation for a tool called SignSupport. SignSupport is a mobile communication tool for Deaf people that currently runs on an Android smartphone. The authoring tool is computer-based software that helps a domain expert, with little or no programming skills, design and populate a limited domain conversation scenario between a Deaf person and a hearing person, e.g., when a Deaf patient collects medication at a hospital pharmacy or when a Deaf learner is taking a computer literacy course. SignSupport provides instructions to the Deaf person in signed language videos on a mobile device. The authoring tool enables the creation and population of such scenarios on a computer for subsequent 'playback' on a mobile device. The output of this authoring tool is an XML script, alongside a repository of media files that can be used to render the SignSupport mobile app on any platform. Our concern now is to iteratively develop the user interface for the authoring tool, focusing on the domain experts who create the overall flow and content for a given scenario. The current authoring tool was evaluated for usability; for both pharmacy and ICDL course scenarios with purposive sampling. The findings suggest that the authoring tool can generalise SignSupport for multiple limited domain scenarios, mobile platforms and signed languages.
