    An IP based multimodal semi-synchronous rural telehealth service: Adding video messaging and conferencing to MuTI
    (Telkom, 2004) Vuza, Xolisa; Tucker, William David
    We intend adding video messaging and conferencing to Multimodal Telemedicine Intecommunicator (MuTI), a previous system that has already been in place in the target environment. This is to allow a semi-synchronous communication to occur over the Internet Protocol. Videoconferencing can be used to communicate synchronously and video messaging in a store and forward fashion can be used to communicate asynchronously. MuTI supports store and forward of still images, voicemail and text. The system also supports real time communication by means of audio. The aim of this research is to learn how to bridge the digital divide by building applications that are useful and relevant to the users we build for. We are developing this application together with the users of the application in an iterative fashion where we build the prototypes and show the users at each cycle. The feedback that we get from the users plays an important role in building a prototype for the next cycle. The software will be instrumented to provide statistics about the system usage. We are also going to get data from the users by using questionnaires and compare this data with the statistics about software usage to see how much the system has been used and which features in the system do the users like. We are using a rural South African context in conducting this research. We hope to bring about guidelines and recommendations on how to develop applications to bridge the digital divide in a developing world context.

    MUTI Telehealth
    (2007) Tucker, William David; Vuza, Xolisa; Chetty, Marshini; Blake, Edwin H.; Marsden, Gary; Pearson, Murray; Westerveld, Rudi
    For four years we have been iteratively evolving MUTI, a rural telehealth system, for hospitals and clinics in a remote rural part of the Eastern Cape in South Africa (Chetty, 2005; Chetty et al., 2003, 2004a; Maunder et al., 2006; Vuza, 2006; Vuza & Tucker, 2004). MUTI enables nurses and doctors to use a wireless Internet Protocol-based communication system to conduct patient referrals, request ambulance services, order supplies and generally keep in contact with one another. The primary community-oriented goal was to prevent unnecessary travel by sick patients from the clinic to the hospital, as transportation in these poverty-stricken and geographically dispersed areas is difficult and expensive for the local inhabitants. We hope that the system can enable nurses at the clinic to learn how to treat a wide range of problems locally by consulting with doctors that they normally do not meet or even speak with. We also hope that the system will lessen the workload for doctors at the hospital. As we expected, integrating new technologies into their everyday work lives is not straightforward or easy.

    Social and technical issues of IP-based multi-modal semi-synchronous communication: rural telehealth communication in South Africa
    (University of the Western Cape, 2005) Vuza, Xolisa; Tucker, William D.; Dept. of Computer Science; Faculty of Science
    Most rural areas of developing countries are faced with problems like shortage of doctors in hospitals, illiteracy and poor power supply. Because of these issues, Information and Communication Technology (ICT) is often sees as a useful solution for these areas. Unfortunately, the social environment is often ignored. This leads to inappropriate systems being developed for these areas. The aims of this thesis were firstly, to learn how a communication system can be built for a rural telehealth environment in a developing country, secondly to learn how users can be supported to use such a system.
