    Improving usability and correctness of a mobile tool to help a Deaf person with pharmaceutical instruction
    (ACM, 2013) Motlhabi, Michael B.; Tucker, William David; Parker, Mariam B.; Glaser, Meryl
    The computing for development community knows how to build user interfaces using qualitative methods for text il- literate users, especially on mobile devices. However, lit- tle work has been done speci cally targeting Deaf users in developing regions who cannot access voice or text. This paper describes a multi-disciplinary collaboration towards iterative development of a mobile communication tool to support a Deaf person in understanding usage directions for medication dispensed at a pharmacy. We are improv- ing usability and correctness of the user interface. The tool translates medicine instruction given in English text to Sign Language videos, which are relayed to a Deaf user on a mo- bile phone. Communication between pharmacists and Deaf patients were studied to extract relevant exchanges between the two users. We incorporated the common elements of these dialogues to represent content in a veri able manner to ensure that the mobile tool relays the correct informa- tion to the Deaf user. Instructions are made available for a Deaf patient in signed language videos on a mobile device. A pharmacy setup was created to conduct trials of the tool with groups of end users, in order to collect usability data with recorded participant observation, questionnaires and focus group discussions. Subsequently, pre-recorded sign language videos, stored on a phone's memory card, were tested for correctness. Results of these two activities are presented and discussed in this paper.

    SignSupport: a limited communication domain mobile aid for a Deaf patient at the pharmacy
    (Telkom, 2013) Motlhabi, Michael B.; Glaser, Meryl; Tucker, William David
    This paper discusses a prototype for a communication aid on a mobile phone to support a Deaf1 person visiting a public hospital pharmacy. The aim is to prevent problems of non-compliance to treatment due to poor communication between a Deaf patient and a pharmacist. We studied the communication exchange between pharmacists and Deaf patients in a pharmacy setting in order to extract the most relevant content exchange between the two parties. A prototype was developed on a mobile phone and iteratively tested using role plays, questionnaires and focus groups with pharmacy students and Deaf participants. The prototype allows pharmacists to input text and make selections that provide detailed medical instructions in signed language to a Deaf patient. The prototype demonstrates the feasibility of encoding a limited communication flow on a mobile device, with carefully sequenced sign language videos that a Deaf patient can watch and understand in order to take medicine correctly.

    Usability and content verification of a mobile tool to help a deaf person with pharmaceutical instruction
    (University of Western Cape, 2014) Motlhabi, Michael B.; Tucker, William
    This thesis describes a multi-disciplinary collaboration towards iterative development of a mobile communication tool to support a Deaf person in understanding usage directions for medication dispensed at a pharmacy. We are improving usability and correctness of the user interface. The tool translates medicine instruction given in English text to South African Sign Language videos, which are relayed to a Deaf user on a mobile phone. Communication between pharmacists and Deaf patients were studied to extract relevant exchanges between the two users. We incorporated the common elements of these dialogues to represent content in a veri able manner to ensure that the mobile tool relays the correct information to the Deaf user. Instructions are made available for a Deaf patient in sign language videos on a mobile device. A pharmacy setup was created to conduct trials of the tool with groups of end users, in order to collect usability data with recorded participant observation, questionnaires and focus group discussions. Subsequently, pre-recorded sign language videos, stored on a phone's memory card, were tested for correctness. Lastly we discuss the results and implications of the study and provide a conclusion to our research.
